BRITISH COLUMBIA PERINATAL HEALTH PROGRAM – PERINATAL DATABASE REGISTRY ANNUAL REPORT 2007 1
The 2007 Annual Report includes perinatal data from fivefiscal years (April 1 to March 31) 2002/2003, 2003/2004,2004/2005, 2005/2006 and 2006/2007. The data provide evi-dence regarding issues pertaining to the care, treatmentand outcomes of mothers and newborns in British Columbia.BC residents who delivered out of province are not capturedin this report. Refer to page 43 Appendix 1 for definitions ofterms used throughout this report.
Some of the key highlights from this report are:
MothersClose to half (46.6%) of the women delivering in BC in 2006/2007were first time mothers.
The average age of women at the time of delivery continues toincrease: in 2006/2007, women were, on average, 30.4 yearsold at the time of delivery. Women having their first babywere, on average, 28.7 years old in 2006/2007, while womenhaving twins or multiples were, on average, 32.5 years old.
Fertility rates are slowly increasing for women in their 30’s,while for other age groups, the fertility rates are stabilizing orslowly declining.
Less than 4% of births in the province are to teenage women.In the Northern Health Authority (HA), however, close to 10%of births are to teenage women. In the last fiscal year, the pro-portion of births to teenage women in the Northern HAincreased 32% (from 7.1% to 9.4%).
Slightly more than 10% of all pregnant women in BC smokedduring their current pregnancy. In the last fiscal year, rates ofsmoking in pregnancy increased in every HA except theVancouver Coastal HA.
The majority of women delivering in BC are of normal weightpre-pregnancy. Rates of pre-pregnancy overweight and obesityare slowing increasing in BC, and together represent approxi-mately 32% of all delivering women with known pre-pregnancyBody Mass Index (BMI). Unknown BMI continues to be an issue:approximately one-third of delivered mothers in BC do not havesufficient information recorded to calculate pre-pregnancy BMI.
Labour & DeliveryApproximately 1 in 5 women had their labour induced in2006/2007. Women delivering in the Interior Health Authorityhad their labour induced more often in 2006/2007 than in anyof the previous four fiscal years. The Provincial HealthServices Authority continues to have the lowest inductionrates in the province (excluding births at home attended byregistered midwives).
The most common method of fetal surveillance in labour is acombination of intermittent auscultation and electronic fetal
monitoring, although rates of (exclusive) intermittent auscul-tation are slowly increasing across the province and rates of(exclusive) electronic fetal monitoring are slowly decreasing.
Less than 15% of women had an episiotomy during vaginaldelivery in the last fiscal year. There is variation throughoutthe province, with the highest rates of episiotomy in theFraser HA at 17%.
Only 60% of women in BC in 2006/2007 had a spontaneous vagi-nal delivery. The next most common method of delivery wasemergent caesarean section (approximately 20%), followed byelective caesarean delivery (slightly more than 11%) and oper-ative vaginal delivery (slightly fewer than 11%). Rates of cae-sarean section delivery continue to increase, while operativeand spontaneous vaginal deliveries continue to decrease.
NewbornsThe number of all births (singletons, twins and multiples) inBC increased from 40,407 in 2002/2003 to 42,198 in 2006/2007.Approximately 3% of births were twins or multiples. TheNortheast Health Service Delivery Area (HSDA) experiencedthe largest increase in the number of singleton births in thelast fiscal year (12.4% increase), while the Northern InteriorHSDA had the largest decrease in the last fiscal year (-3.9%).
The average birth weight for term singletons in BC was 3460grams in 2006/2007 (decreased from 3482 in 2002/2003). Themajority of both term and preterm singletons are average-for-gestational age. Fewer than 10% of term and preterm single-tons are small-for-gestational age.
Just under half of singleton births in BC were delivered byobstetricians, followed closely by family physicians (41.6% in2006/2007). The remaining births were delivered by registeredmidwives (close to 6%) and nurses (less than 3%). Close to10% of births in hospitals within the Vancouver Island HealthAuthority were delivered by registered midwives.
The majority of singletons born in BC received exclusivebreast milk and approximately 5% were formula fed (receivedno breast milk) during the birth admission.
PostpartumPostpartum lengths of stay continue to decrease across BC,after both vaginal and caesarean section delivery. The major-ity of women stay fewer than two days after a vaginal deliveryor fewer than four days after a caesarean delivery.
In 2006/2007, less than 3% of women having caesarean deliv-ery and 2% of women having vaginal delivery were readmittedto hospital (inpatient or same-day surgery) within 42 days ofdelivery for reasons other than routine follow-up. These rateshave increased slightly from the previous year.
HIGHLIGHTS AND EXECUTIVE SUMMARY
The Ministry of Health and the British Columbia MedicalAssociation (BCMA) initiated the British ColumbiaReproductive Care Program (BCRCP) in June 1988. A small, butdedicated group of individuals committed to ensuring thatinformation on perinatal health was made available to a wideaudience of professionals and planners, founded the BritishColumbia Perinatal Database Registry (BCPDR) in 1993.Notably, these individuals included Dr. Sidney Effer, Dr. WilliamJ. Ehman, Dr. Margaret Pendray, Mr. Peter Hayles and Dr. AlanThomson with the support of the BC Ministry of Health. TheBCRCP became part of the Provincial Health Services Authority(PHSA) in 2001 when the government of British Columbia intro-duced five geographically based health authorities and oneprovincial health service authority. In 2007, a new organiza-tional structure – the BC Perinatal Health Program (BCPHP) –was created to coordinate both the BCRCP and the ProvincialSpecialized Perinatal Services (PSPS). The BCPHP continues towork towards optimizing neonatal, maternal and fetal health inthe province through educational support to care providers,outcome analysis and multidisciplinary perinatal guidelines.
The BCPHP is overseen by a Provincial Perinatal AdvisoryCommittee and has representation from the Ministry of HealthServices (MOHS), the Provincial Health Services Authority(PHSA), Children’s and Women’s Health Centre of BC, HealthAuthorities, health care providers and academic organizations.
One of the mandates of the BCPHP is “the collection andanalysis of data to evaluate perinatal outcomes, careprocesses and resources via a province-wide computerizeddatabase”. This mandate led to the development of the BritishColumbia Perinatal Database Registry (BCPDR), with itsstated mission to collect, maintain, analyze and disseminatecomprehensive, province-wide perinatal data for the pur-poses of monitoring and improving perinatal care. Rollout ofthe Registry began in 1994, with collection of data from asmall number of hospital sites. Participation increased everyyear, resulting in full provincial data collection commencingApril 1, 2000. The BCPDR is a relational database containingover 300 fields, and now with complete provincial data, is avaluable source of perinatal information.
Data CollectionThe BCPDR consists of data collected from obstetrical facilitiesas well as births occurring at home attended by BC RegisteredMidwives with records for over 400,000 births currently in theprovincial database.
BC women who deliver in Alberta or in hospitals out of provinceare not captured in the BC Perinatal Database Registry.Therefore data from high outflow communities borderingAlberta will be under-reported.
The perinatal data presented in this report are collected fromfacilities throughout the province and imported into the cen-tral BC Perinatal Database Registry. Data from the CanadianInstitute for Health Information (CIHI) and matched files fromthe British Columbia Vital Statistics Agency complement thedata elements. Mortality data normally reported in the BCPDRAnnual Report consists of singleton pregnancy deaths identi-fied by the BCPDR supplemented by deaths identified by VitalStatistics records, in order to provide complete mortality datafor babies up to one year of age. Due to unavailability of cur-rent mortality information, this section has not been includedin the Annual Report 2007. Please refer to the Annual Report2006 for mortality information.

The 2007 BCPDR Annual Report describes the current state ofperinatal health in British Columbia (BC). In the 2007 AnnualReport, there are five years of data to monitor trends for theselected indicators. The Reports Development Committee haschosen these indicators because they are clinically relevantand lend themselves to analysis that may inform changes inpolicy or care delivery. It must be remembered that thisreport is only one source of data to monitor trends and guidepolicy and clinical practice.
Definitions for terms used throughout the report can be foundin Appendix 1.
Methodological Issues:The 2007 Annual Report includes perinatal data from five fiscalyears (April 1 to March 31) 2002/2003, 2003/2004, 2004/2005,2005/2006 and 2006/2007. Where possible, data for all fiscalyears are reported. Section I includes all deliveries and births,while Sections II and III include only singleton deliveries andbirths. Late terminations are excluded from the entire report.
The data presented in this report are categorized according toeither place of delivery (i.e. where the birth occurs) or placeof residence (i.e. where the mother lives). Data limitations ormethodological issues concerning the data source are notedin the text that accompanies each indicator.
For the purposes of this report, the data contain only linkedmothers and newborns for each fiscal year (<0.02% not
reported). The linked mother-newborn is attributed to the healthcare facility reporting the delivery episode. The year in whichthe linked mother-newborn is contained is dependent on whenthe last individual is discharged (mother or baby). For example:
• if a woman gives birth March 28, 2003 and is dischargedMarch 31, 2003 and the newborn is also discharged March31, 2003, then their information is contained in the2002/2003 fiscal year data.
• if a woman gives birth March 28, 2003 and is dischargedMarch 31, 2003 and the newborn is discharged April 4, 2003,then the data for both mother and newborn will be con-tained in the fiscal year 2003/2004 data set, not the2002/2003 data set.
The updated data for fiscal years 2002/2003, 2003/2004,2004/2005 and 2005/2006 have been incorporated in the 2007Annual Report. Slight differences may, therefore, be notedfrom previous BCPDR Annual Reports and it is advisable thatreaders follow trends based on the current data rather thancompare tables from earlier publications of the annual report.

distribution of these births between singleton and multiplebirths is illustrated in Table 2. Of the births in 2006/2007,51.5% were male; in 2002/2003, 51.4% were male.
BirthsIn 2006/2007, 42,198 babies were born in British Columbia,an increase from 2002/2003 when 40,407 babies were born.This increasing trend in the number of births, along with the
Birth WeightIn 2006/2007, the average birth weight of newborns in BC was3460 grams for term singletons and 2800 grams for term twinsor multiples. Average birth weights have decreased slightlyfrom 2002/2003, when the average birth weight was 3482 gramsfor singletons and 2830 grams for twins or multiples.
ParityOf women delivering in BC in 2006/2007, 46.6% were first-time mothers, an increase from 2002/2003, when 44.9% werenulliparous.
Maternal AgeThe average age of mothers in British Columbia in 2006/2007at the time of delivery was 30.4 years, an increase from2002/2003, when the average age was 30.1 years. The averageage of first-time mothers in BC increased from 28.6 years in2002/2003 to 28.7 years in 2006/2007. The average age ofmothers delivering twins or multiples increased from 31.5years in 2002/2003 to 32.5 years in 2006/2007.
Across Canada the proportion of live births to mothers over theage of 30 has been increasing. In 1991, 34.1% of babies in Canadawere born to mothers over the age of 30; by 2000, this propor-tion had increased to 41.9% [1]. Data from BC Vital Statisticsshows that the proportion of live births to mothers over the ageof 35 in British Columbia has more than doubled over the pasteighteen years, from 8.1% in 1986 to 21.5% in 2005 [2].

Care Provider Delivering Baby by Place of Delivery for Health Service Delivery Areas, Health Authorities and Province, 2002/2003 to 2006/2007 (Refer to Data Table 4A – APPENDIX 10)
The care provider delivering baby indicator identifies the onehealth care provider present at delivery who physically deliv-ers the baby. This person may or may not be the primary careprovider during the hospital admission. He or she may alsodiffer from the care provider who completes the Notice ofBirth for submission to the Vital Statistics Agency. For thisreport, the care provider delivering the baby was analyzed byplace of delivery and includes only singleton deliveries. SeeAppendix 1 for an explanation of care provider deliveringbaby categories.
The 2007 National Physician Survey (NPS) shows that while61.1% of family physicians provide some form of maternitycare in pregnancy, only 11.1% provide intrapartum care [3]. Ofthose family physicians providing intrapartum care, 55.9%attend 50 or fewer births per year [3]. While increases in deliv-eries by registered midwives may help to explain this decline,the sustained increase in deliveries by obstetricians may alsobe a contributing factor. With an aging workforce (the averageage of physicians responding to the 2007 NPS was 50.1 years[3]), human resources planning in maternity care will becomeincreasingly more important. Many health planners and pro-fessional organizations, including the Society of Obstetriciansand Gynaecologists of Canada [4], are developing healthhuman resource strategies to plan for anticipated shortages.
Over the past five years, there have been slight increases inBC in the proportion of deliveries by obstetricians (49.9% in2006/2007 compared to 48.2% in 2002/2003) and a largerdecrease in the proportion of deliveries by family physicians(41.6% in 2006/2007 compared to 44.3% in 2002/2003), whichhave been largely offset by an increase in the proportion ofdeliveries by registered midwives (5.8% in 2006/2007 com-pared to 3.7% in 2002/2003).
In the past five fiscal years, there has been a large increase insingleton deliveries by obstetricians in the Interior HealthAuthority (32.3% to 37.3%), Vancouver Coastal HealthAuthority (51.5% to 57.0%) and Vancouver Island HealthAuthority (44.7% to 48.5%). During the same period, deliver-ies by obstetricians within the Provincial Health ServicesAuthority (PHSA) have decreased slightly, from 69.7% to67.6%, although this health authority still has the highest pro-portion of deliveries by obstetricians than any other healthauthority or health service delivery area in BC. KootenayBoundary Health Service Delivery Area (HSDA) had the low-est proportion of deliveries by obstetricians in 2006/2007 at18.8%; in 2002/2003, 36.9% of deliveries in this HSDA were byobstetricians.
Deliveries by registered midwives (at home or in hospital)in BC continue to increase. In 2002/2003, 3.7% of singletondeliveries were by midwives; in 2006/2007, this proportionincreased to 5.8%. This represents a 56.8% increase since2000/2001, when midwives delivered 2.7% of singletons inBC [5]. In 2006/2007, the largest proportion of hospitaldeliveries by midwives were in the North Vancouver IslandHSDA (increased from 10.1% to 16.0% over the past five fiscalyears) and within the Kootenay Boundary HSDA (increasedfrom 6.8% to 13.6%).
Although hospital deliveries by nurses continue to decreaseprovincially (2.8% in 2006/2007), in the Fraser Health Authority,nurses delivered more than midwives. For example, in2006/2007, nurses delivered 4.5% of singletons in the FraserHealth Authority (606 newborns), compared to 2.7% deliveredby midwives (363 newborns).
As many data sources, both nationally and provincially, can-not measure the involvement of every care provider type inthe care of the patient or referral patterns from antenatal careto admission for delivery, the prevalence and influence ofthese care providers may be underreported.

12 BRITISH COLUMBIA PERINATAL HEALTH PROGRAM – PERINATAL DATABASE REGISTRY ANNUAL REPORT 2007(Only singleton deliveries and births included)
Teen Birth Rate by Place of Residence for Health Service Delivery Areas, Health Authorities and Province, 2002/2003 to 2006/2007 (Refer to Data Table 5A – APPENDIX 10)
The teen birth rate is defined as the number of deliveries tomothers 19 years of age or younger at the time of delivery, ata given place and time and expressed as a proportion of thetotal number of mothers, of any age, who deliver during thesame time and at the same place. For this report, teen birthrate was analyzed by place of residence and includes only sin-gleton deliveries.
Despite an overall decrease in the proportion of births toteens over the past five years, the proportion of singletonbirths to mothers aged 19 and younger (at the time of deliv-ery) increased from 3.3% in 2005/2006 to 3.6% in 2006/2007. Inthe years prior to 2006/2007, the proportion of all teen birthsin BC decreased from 4.0% in 2002/2003 to 3.6% in 2006/2007.The largest increase in teen births over the last five fiscalyears was in the Northern Health Authority (NHA), where theproportion of births to mothers between the ages of 18 and 19years increased from 5.4% in 2002/2003 to 6.8% in 2006/2007.
In the younger subset of teenaged mothers (<–17 years), theproportion of births decreased from 1.3% in 2002/2003 to1.1% in 2006/2007. The NHA, however, has a large proportionof births in this group. Specifically, in the Northwest HealthService Delivery Area (HSDA) 3.8% of deliveries in 2006/2007
were to women in this younger age group. Conversely, only0.3% of deliveries to residents of Richmond HSDA were towomen <–17 years of age in 2006/2007. In fact, the NorthwestHSDA has the largest proportion of births to teens (11.5% in2006/2007), followed by the Northeast HSDA with 9.3% andthe Northern Interior HSDA with 8.3%.
As teenage mothers have been associated, in the literature,with health indicators such as smoking and repeat pregnancyand their births have been associated with outcomes such aslow birth weight, spontaneous vaginal delivery rates, andpreterm delivery [6-8], further analysis was completed. In BCin 2006/2007, the prevalence of smoking in pregnancy was34.0% in teenage mothers compared to 9.8% in non-teenagemothers [9]. Of the teens who delivered in BC in 2006/2007,11.5% were parity >– 1 [9], consistent with 2005/2006 at 11.1%[10]. The average birth weight of term singletons born toteenage mothers in BC in 2006/2007 was 3475.1 grams com-pared to 3491.8 grams in non-teenage mothers [9]. Pretermbirth rates among teenaged mothers in BC in 2006/2007, were10.1%, compared to 8.1% in non-teenaged mothers [9]. Ratesof spontaneous vaginal delivery of singletons for teenagemothers were 71.0% in BC in 2006/2007 compared to 59.5% ofnon-teenaged mothers [9].

14 BRITISH COLUMBIA PERINATAL HEALTH PROGRAM – PERINATAL DATABASE REGISTRY ANNUAL REPORT 2007(Only singleton deliveries and births included)
SECTION II
Maternal Smoking Rate by Place of Residence for Health Service Delivery Areas, Health Authorities and Province, 2002/2003 to 2006/2007 (Refer to Data Table 6A – APPENDIX 10)
The maternal smoking rate is defined as the number of preg-nant women who were reported to have smoked at any timein the current pregnancy expressed as a proportion of thetotal number of pregnant women at a given time and place.For this report, maternal smoking rates are reported by placeof residence and include only singleton deliveries.
Smoking in pregnancy and exposure to second hand smokeduring pregnancy has been associated with specific adverseoutcomes in the fetus and newborn as well as increased riskof pregnancy related complications. Increased risk of pretermbirths, stillbirths, low birthweight, and placental abruptionare a few of these adverse outcomes [11]. Although manywomen attempt to quit smoking after learning of her preg-nancy, these women may cycle through cessation attemptsand relapses throughout pregnancy, making it difficult tomonitor these fluctuations [12]. The longer a pregnant womansmokes during pregnancy, the greater the risk to her fetus. Ithas been shown, however, that cessation of smoking at anytime during pregnancy is beneficial [13]. Women who smokein pregnancy, therefore, should be encouraged to quit smok-ing at the start of her pregnancy as well as throughout thepregnancy and have access to adequate and appropriatesmoking cessation material.
The BC government announced the ActNow BC initiative in2005 to be achieved by 2010. For pregnant women, this initia-tive encourages healthy choices during pregnancy includinghealthy eating, increased physical activity, reduction intobacco use, reduction in overweight and obesity andincreased awareness of fetal alcohol spectrum disorder [ActNow BC – Welcome].
There are large differences in the rates of smoking in preg-nancy in BC. While the provincial prevalence of smoking inpregnancy has been relatively stable for the past five fiscalyears (10.7% in 2006/2007), rates are persistently high in cer-tain parts of the province. Specifically, the Northern HealthAuthority (NHA) had the highest smoking in pregnancy ratesin the province for the last five fiscal years, with a rate of18.7% in 2006/2007, followed by the IHA at 16.4% and theVIHA at 16.2%. Conversely, rates of smoking in pregnancy inthe Vancouver Coastal Health Authority have remained thelowest in the province for the last five years, at 5.2% in2002/2003 and 4.0% in 2006/2007.
The highest rates of smoking in pregnancy in any HealthService Delivery Area in BC in 2006/2007 was in the NorthernInterior, where approximately 1 in 5 women smoked in thecurrent pregnancy (20.6%). Richmond Health ServiceDelivery Area had the lowest rate of smoking in pregnancy in2006/2007, at 3.0%. While smoking in pregnancy rates are gen-erally decreasing across the province, the majority of theHealth Service Delivery Areas within the Vancouver IslandHealth Authority and the Northern Health Authority haveseen increasing rates from 2002/2003 to 2006/2007.

16 BRITISH COLUMBIA PERINATAL HEALTH PROGRAM – PERINATAL DATABASE REGISTRY ANNUAL REPORT 2007(Only singleton deliveries and births included)
SECTION II
Induction of Labour Rate by Place of Delivery for Health Service Delivery Areas, Health Authorities and Province, 2002/2003 to 2006/2007 (Refer to Data Table 7A – APPENDIX 10)
The induction of labour rate is defined as the number of moth-ers whose labour is artificially initiated by medical (oxytocinand/or prostaglandin) or surgical (artificial rupture of mem-branes) means prior to the onset of spontaneous labour,expressed as a proportion of the total number of motherswho delivered at the same time and place. For this report,labour induction rates are reported by place of delivery andinclude only singleton deliveries. See Appendix 1 for the BCPerinatal Database Registry definition of induction used inthis report.
Approximately 1 in 5 pregnant women in British Columbia hadlabour induced by artificial (medical or surgical) means in2006/2007. As a method of initiation of labour, in addition tospontaneous labour or caesarean section before labour com-mences, inducing labour is an option that can be undertakenfor a number of reasons. These include post-term pregnancy,maternal conditions (such as gestational diabetes or hyper-tension), pre-labour rupture of membranes, evidence of fetalcompromise, fetal death, or other logistical or geographicalconstraints. In fact, in 2006/2007 the most common primaryindication for induction of labour in singleton pregnancieswas post-term pregnancy (36.7% of all inductions); this hasremained the most common primary indication for inductionsince 2000/2001 [14].
Although labour induction can be beneficial in certain situa-tions, it is also associated with a number of risks to bothmother and baby. Current BCPHP Guidelines recommend thatinduction of labour should only be undertaken after dis-cussing the known risks with the mother and her partner andthat elective induction of labour without clearly identifiedmedical or clinical indication should be avoided [15].
Induction of labour has been associated with many conditionsincluding increased risk of caesarean delivery, longer labour,fetal compromise and uterine hyperstimulation [16]. The sig-nificance of these risk factors and the potential success (orfailure) of labour induction can vary with such factors as thecondition of the cervix, maternal age, parity, maternal bodymass index and timing of induction (e.g. pre-term vs. post-term induction) [17, 18]. Induction should only occur afterconsideration for these factors, accurate assessment of gesta-tional age, and after analysis of risks of continuing the preg-nancy without induction. Labour induction in pregnantwomen with a history of previous caesarean section shouldbe cautiously considered, as the risk of uterine rupture asso-ciated with labour induction in this subset of women, whileremote, has severe consequences [19].
In BC, labour induction rates have been stable for the past fivefiscal years, at 21.5% in 2002/2003 and 21.2% in 2006/2007,and a low of 20.0% in 2004/2005. The PHSA, followed by theNorthern Health Authority had the lowest labour inductionrate in 2006/2007, at 16.4% and 19.9% respectively, excludinghome births. The Interior Health Authority had the highestlabour induction rate, at 24.5%.
Pregnant women delivering in the Fraser North and KootenayBoundary Health Service Delivery Areas (HSDA) had thehighest rates of labour induction in 2006/2007, at 26.7%, withdeliveries occurring in the East Kootenay HSDA followingclosely behind at 24.7%. Births at home consistently havethe lowest rates of labour induction; among facility-baseddeliveries, those occurring in Northern Interior had the low-est rates of labour induction in 2006/2007, at 18.1%. SouthVancouver Island has shown the largest decrease in induc-tion rates from 27.5% in 2002/2003 to 22.5% in 2006/2007,while all the Health Service Delivery Areas in the InteriorHealth Authority continue to show a trend of increasinglabour induction rates.

SECTION II
Fetal Surveillance During Labour by Place of Delivery for Health Service Delivery Areas, Health Authorities and Province, 2004/2005 to 2006/2007(Refer to Data Table 8A – APPENDIX 10)
Fetal surveillance during labour is defined as the number ofmothers receiving electronic fetal monitoring, intermittentauscultation, a combination of electronic fetal monitoring andintermittent auscultation, or no fetal surveillance duringlabour, expressed as a proportion of the total number ofmothers who laboured and delivered at the same time andplace. Prior to 2004/2005, reporting of fetal surveillance dur-ing labour was limited to describing whether the mother hadelectronic monitoring during labour or not. Intermittent aus-cultation was not collected in the BCPDR until 2004/2005. Forthis report, fetal surveillance during labour was analyzed byplace of delivery and includes only singleton deliveries.
A recently (2007) revised guideline, jointly developed by theBCPHP and the Society of Obstetricians and Gynaecologists ofCanada, recommends intermittent auscultation in labour forhealthy term women in spontaneous labour in the absence ofrisk factors for adverse perinatal outcome, as opposed to elec-tronic fetal monitoring [20]. Many studies and meta-analyseshave shown that electronic fetal monitoring should be used inlow-risk pregnancies only if adverse risk factors develop orintermittent auscultation becomes non-reassuring [21, 22].
In British Columbia, use of intermittent auscultation duringlabour increased, from 18.8% in 2004/2005 to 22.8% in2006/2007, while the use of electronic fetal monitoring inlabour decreased, from 31.5% in 2004/2005 to 26.6% in2006/2007. In BC, almost 6% of women are not monitored inlabour. Vancouver Island Health Authority had the highestrate of intermittent auscultation (27.2%) and the lowest rateof electronic fetal monitoring (19.0%), while 47.0% of womenin labour had a mix of electronic fetal monitoring and inter-mittent auscultation (2006/2007). The highest rate of elec-tronic fetal monitoring in 2006/2007 was in the NorthernHealth Authority, at 38.6%, although this was a dramaticdecrease from 52.2% in 2005/2006. Deliveries occurring athome have consistently had the highest rates of intermittentauscultation (93.0% in 2004/2005 and 93.7% in 2006/2007).
North Vancouver Island Health Service Delivery Area (HSDA)had the highest rate of intermittent auscultation in 2006/2007,excluding home births at 37.5%, followed closely by EastKootenay HSDA at 36.7%. While the Northern Interior HSDAand the Northeast HSDA had the highest rates of exclusiveelectronic fetal monitoring in 2006/2007 at 44.4% and 41.1%respectively, these HSDAs both demonstrated declines inrates since 2004/2005. Simultaneously, the Northeast HSDAincreased its intermittent auscultation rate from 3.2% in2005/2006 to 23.3% in 2006/2007.

20 BRITISH COLUMBIA PERINATAL HEALTH PROGRAM – PERINATAL DATABASE REGISTRY ANNUAL REPORT 2007(Only singleton deliveries and births included)
SECTION II
Episiotomy Rate by Place of Delivery for Health Service Delivery Areas, Health Authorities and Province, 2002/2003 to 2006/2007(Refer to Data Table 9A – APPENDIX 10)
The episiotomy rate is defined as the number of mothers hav-ing an episiotomy during vaginal delivery expressed as a pro-portion of the total mothers delivering vaginally during thesame time and within the same place. For this report, epi-siotomy rates were analyzed by place of delivery and includeonly singleton deliveries.
The Society of Obstetricians and Gynaecologists of Canada rec-ommends that episiotomy is not necessary for an assisted vagi-nal birth [23]. A systematic review by Hartmann et al in 2005also concluded that there were no improved outcomes from epi-siotomy, and that in some circumstances, the use of episiotomymay increase morbidity [24]. Despite this evidence andalthough the use of episiotomy has decreased substantiallyover the last twenty years, it persists in many countries, withvariation among regions, hospitals and care providers [25-27].
Across British Columbia, rates of episiotomy in vaginal deliv-eries have stabilized in the past two fiscal years, reaching alow of 14.1% in 2006/2007. The Fraser Health Authority (FHA),Provincial Health Services Authority (PHSA), and theVancouver Coastal Health Authority (VCHA) had slightlyhigher episiotomy rates than the provincial average in
2006/2007, at 17.5%, 16.0% and 15.0% respectively. Over thepast five fiscal years, the PHSA has had the largest drop inrates, from a high of 23.6% in 2002/2003 to 16.0% in 2006/2007.Conversely, the Interior Health Authority has had the moststable episiotomy rates in the past five fiscal years, with a rateof 11.4% in 2002/2003 (the lowest in the province that year,excluding home births), and 10.3% in 2006/2007 (the lowestrate in the province that fiscal year, excluding home births).Home births have had a slight increase in episiotomy rates inthe last fiscal year, increasing to a high of 1.4% in 2006/2007.
The highest episiotomy rate in 2006/2007 in any of the HealthService Delivery Areas in BC was in Fraser South and Richmond,where 21.5% and 21.4%, respectively, of women delivering vagi-nally had an episiotomy. Women with the lowest likelihood ofepisiotomy in vaginal delivery in 2006/2007, excluding homebirths, delivered in Kootenay Boundary (6.2%). Although thereis a wide range of rates across the province, all Health ServiceDelivery Areas have had a decrease in episiotomy in vaginaldelivery rates from 2002/2003 to 2006/2007, except theOkanagan Health Service Delivery Area, where there was avery slight increase in rates, from 12.6% in 2002/2003 to 13.7%in 2006/2007.

22 BRITISH COLUMBIA PERINATAL HEALTH PROGRAM – PERINATAL DATABASE REGISTRY ANNUAL REPORT 2007(Only singleton deliveries and births included)
SECTION II
Postpartum Length of Stay (Vaginal Deliveries) by Place of Delivery for Health Service Delivery Areas, Health Authorities and Province, 2002/2003 to 2006/2007(Refer to Data Table 10A – APPENDIX 10)
Postpartum length of stay is defined as the amount of time, inhours, from delivery of the infant to maternal discharge fromthe hospital. For this report, postpartum lengths of stay weregrouped into time ranges and the number of mothers in eachrange was expressed as a proportion of the total number ofwomen delivering. Postpartum length of stay was analyzed byplace of delivery and reported separately for vaginal and forcaesarean deliveries. As mothers who deliver at home are notdischarged from care in the same manner as mothers whodeliver in a hospital, only deliveries occurring in hospitalswere included in the length of stay analysis. In addition,lengths of stay for maternal transfers to other facilities afterdelivery were not included in this analysis.
The duration of postpartum length of stay in hospital aftervaginal delivery continues to decline in British Columbia.Provincially, in 2006/2007, 72.5% of mothers having a vaginaldelivery of a singleton stayed in hospital less than 48 hourspost-delivery. In 2002/2003, 66.9% of mothers having a vaginaldelivery of a singleton stayed in hospital less than 48 hoursand in 2000/2001, this percentage was 61.9% [14].
While the proportion of mothers staying in hospital for lessthan 48 hours post-delivery continues to increase across theprovince, Fraser Health Authority continues to have the largestproportion of mothers with the shortest postpartum length-of-stay. In 2006/2007, 82.0% of women delivering within the FraserHealth Authority left within two days of delivering, comparedto 66.0% of women delivering in Vancouver Island HealthAuthority (VIHA). The VIHA and the Interior Health Authorityhad the largest proportion of women who remained in hospitalfor at least 72 hours (3 days) after vaginal delivery of a single-ton in 2006/2007 (11.2% and 12.2% respectively). Variationamong Health Service Delivery Areas (HSDAs) in BC showsthat 30.0% of women who delivered in Kootenay Boundarystayed between two and three days in hospital postpartum(2006/2007), compared to only 9.8% of women who deliveredin the Fraser South HSDA.

Postpartum Length of Stay (Caesarean Section Deliveries) by Place of Delivery for Health Service Delivery Areas, Health Authorities and Province, 2002/2003 to 2006/2007(Refer to Data Table 11A – APPENDIX 10)
Postpartum length of stay is defined as the amount of time, inhours, from delivery of the infant to maternal discharge fromthe hospital. For this report, postpartum lengths of stay weregrouped into time ranges and the number of mothers in eachrange was expressed as a proportion of the total number ofwomen delivering. Postpartum length of stay was analyzed byplace of delivery and reported separately for vaginal and forcaesarean deliveries. Only deliveries occurring in hospitalswere included in the length of stay analysis. In addition,lengths of stay for maternal transfers to other facilities afterdelivery were not included in this analysis.
The proportion of mothers staying in hospital after caesareansection for longer than 96 hours is decreasing provincially. In2006/2007, only 13.7% of mothers stayed longer than 96 hoursafter delivering by caesarean section. In 2002/2003, 19.9% ofmothers had a postpartum length of stay of at least 96 hours(4 days) post-caesarean section.
Vancouver Island Health Authority had the largest proportionof mothers staying greater than 96 hours post-caesarean sec-tion compared to other Health Authorities in 2006/2007, at19.9%. This is a decrease from 2002/2003, where 29.6% ofmothers delivering within VIHA stayed in hospital at least 96hours post-caesarean. Conversely, women who had a cae-sarean section in facilities within the Fraser Health Authorityhave the lowest likelihood of staying longer than 96 hourspostpartum. In 2006/2007, only 7.0% of women did so, which isa decline from 10.5% in 2002/2003. With the lowest caesareansection rate in the province in 2006/2007 at 22.8%, KootenayBoundary Health Service Delivery Area (HSDA) has the highestproportion of mothers who stay longer than 96 hours post-cae-sarean section, at 46.9%.

SECTION II
Pre-pregnancy Body Mass Index (BMI) by Place of Residence for Health Service Delivery Areas,Health Authorities and Province, 2002/2003 to 2006/2007(Refer to Data Table 12A – APPENDIX 10)
Pre-pregnancy body mass index (BMI) is defined as the ratioof a woman’s weight to height, as measured pre-pregnancy, orup to 12 weeks gestation. It is calculated using the formula:BMI = weight (kg)/height (m)2. For this report BMI was calcu-lated and grouped according to the classification schemedescribed below. Body mass index was reported by place ofresidence and includes only singleton deliveries.
The association between pre-pregnancy overweight andobesity and adverse outcomes such as caesarean section,macrosomia, gestational hypertension, pre-eclampsia, andgestational diabetes are well documented in the literature[28-31]. As well, women who are underweight pre-pregnancymay also have increased risk for low birth weight newborns[29]. In 2006/2007, singletons born to women in BC who were
Throughout BC, residents of Health Authorities demonstratedifferent patterns of pre-pregnancy BMI categories. For exam-ple, residents of the Northern Health Authority have higherlevels of pre-pregnancy obesity than other health authorities.As well, these pre-pregnancy obesity rates have increased,from 17.3% in 2002/2003 to 20.0% in 2006/2007. Pre-pregnancyobesity rates have increased in the Interior Health Authority(from 12.4% to 14.0%), the Vancouver Coastal Health Authority(from 5.3% to 5.7%), and the Fraser Health Authority (from11.2% to 12.3%). Vancouver Coastal Health Authority is theonly health authority in BC whose rates of pre-pregnancyunderweight (8.8% in 2006/2007) are higher than its rates ofpre-pregnancy obesity (5.7% in 2006/2007).
Table 12 Health Risk Classification According to Body Mass Index (BMI) [47]
Classification BMI Category (kg/m2) Description
Underweight < 18.5 Increased risk
Normal Weight 18.5 - 24.9 Least risk
Overweight 25.0 - 29.9 Increased risk
Obese >– 30.0 High to extremely high risk

Source: Health Canada. Canadian Guidelines for Body Weight Classification in Adults. Ottawa: Minister of Public Works and Government Services Canada; 2003
Of concern are the high rates of unclassified pre-pregnancyBMI, indicating that one or both of the maternal pre-pregnancyweight and height fields are incomplete on the maternalrecord. In BC in 2006/2007, approximately one-third (32.2%) ofrecords were incomplete in this category. Across the province,rates of unclassified pre-pregnancy BMI in 2006/2007 vary from26.9% in the Vancouver Island Health Authority to 50.9% in theNorthern Health Authority. The difference is more dramatic byHealth Service Delivery Area, from lows of 6.2% in SouthVancouver Island and 16.2% in Fraser South to highs of 56.4%in Fraser East and 68.6% in the Northwest. With the additionof the pre-pregnant BMI field to the recently revised AntenatalRecord Part 1 in BC, it is hoped that the heightened awarenessof the importance of these fields will result in more completeand accurate documentation of these elements to monitor pre-pregnancy BMI.
obese pre-pregnancy (as defined in Table 12, below) had anaverage birth weight of 3661 grams, while singletons born tonormal weight women had an average birth weight of 3457grams, and for underweight mothers, 3279 grams [9].
The majority of women in BC are normal weight (as defined inTable 12, below) pre-pregnancy. In 2002/2003, 62.7% of womenwith known i pre-pregnancy BMI were normal weight, and in2006/2007, this proportion dropped slightly to 61.6%. Rates ofunderweight pre-pregnancy BMI are also decreasing in BC,with a decline from 7.3% in 2002/2003 to 6.5% in 2006/2007.Pre-pregnancy obesity on the other hand, is increasingslightly, and taken together, pre-pregnancy overweight andobesity have increased from 30.0% of all singleton pregnan-cies in 2002/2003 to 31.8% in 2006/2007.
i ‘Known’ denotes the presence of a recorded pre-pregnancy weight and height on the maternal record. Women with one or both of these values missing weregrouped into the ‘unclassified’ BMI category

SECTION II
Maternal Postpartum Readmission to Hospital by Place of Delivery for Health Service Delivery Areas, Health Authorities and Province, 2002/2003 to 2005/2006(Refer to Data Table 13A – APPENDIX 10)
Postpartum readmission to hospital is defined as any motherwho is readmitted to hospital, as an inpatient or surgical daycare patient, within 42 days of delivery. Readmissions for rou-tine follow-up care have been excluded. For this report, post-partum readmission was analyzed by hospital of delivery,although the readmission could be to any facility in BC (notnecessarily the same as the delivery facility), and includesonly singleton deliveries.
Rates of postpartum readmission to hospital have increasedslightly in the province of BC, after both caesarean sectionand vaginal deliveries. For vaginal deliveries, rates of readmis-sion have increased from 1.5% of all deliveries in 2002/2003 to2.0% in 2005/2006, while readmission after caesarean sectiondelivery have increased from 2.1% in 2002/2003 to 2.7% in2005/2006. All Health Authorities in BC have had an increasein postpartum readmission rates, for both vaginal and cae-sarean deliveries since 2002/2003. Although most HealthAuthorities have higher rates of postpartum readmission
following caesarean delivery, the Northern Health Authorityhad a higher postpartum readmission rate following vaginaldelivery than caesarean delivery (2.8% compared to 2.2%) in2005/2006. Rates of postpartum readmission following birthsat home are the lowest in the province along with theRichmond Health Service Delivery Area (HSDA) (both at 1.0%of all deliveries in 2005/2006).
The highest rates of postpartum readmission in 2005/2006were following caesarean delivery in the Thompson-Cariboo-Shuswap HSDA and North Vancouver Island HSDA, where4.3% of mothers delivering were readmitted postpartum.Readmission rates following vaginal delivery were highest in2005/2006 in the Northeast and Central Vancouver IslandHSDAs (both at 2.9%), followed closely by the NorthwestHSDA (2.8%) and Fraser East HSDA (2.8%). More detailedanalysis of the reasons for readmission will be possible withthe collection of postpartum readmission data in the newversion of the BC Perinatal Database beginning with April2008 discharges.

30 BRITISH COLUMBIA PERINATAL HEALTH PROGRAM – PERINATAL DATABASE REGISTRY ANNUAL REPORT 2007(Only singleton deliveries and births included)
SECTION II
Method of Delivery Rate (Vaginal vs. Caesarean Section) by Place of Delivery for Health Service Delivery Areas, Health Authorities and Province, 2002/2003 to 2006/2007(Refer to Data Tables 14A and 15A – APPENDIX 10)
The method of delivery is defined as the type of delivery (spon-taneous vaginal, assisted vaginal or caesarean section) themother had. For this report, method of delivery was analyzedby place of delivery and includes only singleton deliveries.
In 2005/2006, the caesarean section rate in British Columbia(BC) for all births (singletons, twins and multiples) reached anational high of 30.4%, higher than the Canadian rate of 26.3%and surpassing every other province and/or territory inCanada to have the highest rate [32]. Caesarean delivery isassociated with specific maternal health risks, such as hem-orrhage, puerperal infection, anesthetic complications, andemergency hysterectomy [33, 34], as well as risk in subse-quent pregnancies that include higher incidence of placentaprevia, placenta accreta, abdominal adhesions, and repeatcaesarean sections [35-37]. Infant and neonatal health risksassociated with caesarean section have been found to behigher than for those infants delivered vaginally and includehigher respiratory morbidity rates, neonatal intensive careadmission rates, and neonatal mortality [38-41]. Despite theserisks, caesarean delivery rates continue to rise. Concurrentwith these increases are concerns over loss of skill set to per-form instrumental vaginal delivery, lowering thresholds tomake the decision to perform caesarean section, and the effectof obstetricians increasing their role in primary care of preg-nant women. As well, changing maternal demographics, suchas increasing maternal age and pre-pregnancy weight havealso been associated with changes in caesarean section rate[42]. Despite a perception that many women are requestingcaesarean section without medical indication, this trend hasyet to be substantiated in the scientific literature.
In 2006/2007, (Table 14) the Northern Health Authority contin-ued to have the lowest caesarean section rate in the province,at 26.5%. In fact, the Northern Health Authority is the onlyHealth Authority with a caesarean section rate that has notincreased since 2002/2003. Vancouver Island Health Authorityhad the highest caesarean section rate in 2006/2007 at 31.5%.
Vancouver Coastal Health Authority (VCHA) had the highestelective caesarean section rate in 2006/2007, (Table 15) at13.0% of all deliveries, an increase from 9.9% in 2002/2003. In2006/2007, Vancouver Island Health Authority had the highestemergent caesarean section rate in the province, at 21.3% of alldeliveries. All of the Health Authorities, except for VancouverCoastal Health Authority, have had increases in emergent cae-sarean section rates over the last five fiscal years.
Rates of operative vaginal deliveries (Table 15) have beenconsistently the lowest within the Vancouver Island HealthAuthority for the past five years. In contrast, the Fraser HealthAuthority and the Provincial Health Services Authority (PHSA)had the two highest rates of operative vaginal delivery in2006/2007, at 12.7% and 13.3% respectively. In fact, in 2006/2007,these two health authorities (FHA and PHSA) were the only twohealth authorities whose operative vaginal delivery rates werehigher than their elective caesarean section rates.
In February 2008, BCPHP released the findings of the CaesareanBirth Task Force, which culminated the work of 18 months ofexamination of trends and discussion of recommendations forthe province with an aim to optimize caesarean delivery ratesand identify factors that have contributed to the rise in cae-sarean section rates. In January 2008 a Caesarean ConsensusConference was held to discuss collaboration at the local,regional and provincial level to optimize caesarean birth.The final report of the Caesarean Birth Task Force, whichincludes the consensus statement from the CaesareanConsensus Conference, can be accessed at the BCPHP web-site: http://www.bcphp.ca/

34 BRITISH COLUMBIA PERINATAL HEALTH PROGRAM – PERINATAL DATABASE REGISTRY ANNUAL REPORT 2007(Only singleton deliveries and births included)
Newborn Feeding by Place of Delivery for Health Service Delivery Areas, Health Authorities and Province, 2004/2005 to 2006/2007 (Refer to Data Table 16A – APPENDIX 10)
Newborn feeding is defined as the number of singleton live-born infants breastfed, either exclusively or supplementedwith breast milk substitutes (formula) during the birth admis-sion, expressed as a proportion of all singleton live borninfants. See Appendix 1 for the BCPDR categorizations of new-born feeding. As this field captures data that reflects activityduring the hospital admission, newborn feeding for birthsthat occur at home were not included in the analysis.
Breastfeeding has been demonstrated to be the most benefi-cial method to provide optimum nutritional and emotionalhealth benefits to newborns and infants, and has been shownto contribute to positive health outcomes into childhood aswell. These benefits include a reduction in the incidence ofmany conditions in the newborn, including diarrhea, otitismedia, and respiratory tract infections, with additional litera-ture associating breastfeeding with a reduction in the inci-dence of asthma and allergies in childhood [43-45]. Benefits tothe mother include reduced risk of ovarian and uterine cancer,more rapid uterine involution, weight loss post-pregnancy, anda protective effect on maternal bone mineral density [45]. TheWorld Health Organization advocates the promotion of exclu-sive breastfeeding, with complementary feeding supplementa-tion for up to two years of age and beyond [44]. In 1991, theWHO/UNICEF developed a world-wide initiative, the 10 Stepsfor Baby Friendly Hospitals as a way of supporting and recog-nizing facilities providing the best practices in the protection,promotion and support of breastfeeding [44]. To date, BritishColumbia has one hospital, GR Baker Memorial Hospital inQuesnel that has achieved Baby-Friendly designation.Promotion and support of exclusive breastfeeding should beframed in the context of these benefits, while recognizing thatbarriers to breastfeeding may still exist (e.g. hospital policies,maternal education about how to breastfeed, lack of continu-ous support from family members or other support groups,separation at birth/delayed contact after birth due to NICUadmission or caesarean section, etc.) [48].
Beginning with April 1, 2004 discharges, the BCPDR began col-lecting data on newborn feeding during the birth admissionbased on the Breastfeeding Committee for Canada (BCC) def-initions, which have also been adopted by the CanadianPerinatal Program Coalition Committee as the definitionsused by Perinatal Programs [46]. Because of this, reporting ofthis field can only begin with 2004/2005 data and may reflecta transition period as the new definitions are adoptedthroughout the province. The effects of the change in this def-inition as well as continued efforts from Health Authoritiesthroughout BC to achieve ‘Baby-Friendly’ designation are justbeginning to be reflected in this data indicator.
In 2006/2007 in BC, 69.2% of newborns were reported to beexclusively breastfed during the birth admission, a slightdecrease from 2004/2005 when the exclusive breastfeedingrate was 69.5%. Breast milk substitute (formula) feeding dur-ing the birth admission accounted for only 4.8% of singletonsdeliveries in 2006/2007, a decrease from 5.6% in 2004/2005.Throughout the province, the majority of singleton newbornswere reported to receive exclusive breast milk during thebirth admission, with some differences between HealthAuthorities. Vancouver Island Health Authority reported thehighest rates of exclusive breastfeeding at 79.1% in 2006/2007,while the Provincial Health Services Authority reported thelowest rate in 2006/2007 at 60.5%. Breast milk substitute(formula) feeding rates were reported the highest in theNorthern Health Authority in 2006/2007, with 8.2% of single-ton newborns receiving only formula (no breast milk) dur-ing the birth admission. This is a decline from 2004/2005,when the rate was 10.2%.

SECTION III
Changes in Birth Rate by Place of Residence for Health Service Delivery Areas, Health Authorities and Province, 2000/2001 to 2006/2007
The birth rate change is defined as the change in the numberof singleton births by fiscal year and expressed as a percent-age increase or decrease. For this report, birth rate changesare analyzed two different ways: the overall birth rate changecompares the change in number of births over seven fiscalyears (2000/2001 to 2006/2007), while the remaining reportedbirth rates compare each fiscal year to the previous one. Onlysingleton deliveries of live births and stillbirths were included,and were analyzed by place of residence.
The number of singleton births in the province of BritishColumbia has increased from 39,412 to 40,878 [9], a +3.7%increase over the past seven fiscal years. Analysis of changesin overall birth rate, comparing 2000/2001 to 2006/2007,shows disparity throughout the province with VancouverIsland Health Authority showing the largest increase in over-all birth rate at +6.8%, followed closely by the Fraser HealthAuthority with +6.4%, and the Northern Health Authorityshowing a decrease of -2.6% (Figure 15).
Fluctuations in birth rates exist from year to year as well(Table 17). For example, in the last fiscal year (2006/2007 com-pared to 2005/2006), BC had a +3.0% increase in birth rate. Inaddition, every Health Authority except for the NorthernHealth Authority and the Vancouver Island Health Authorityhad an increase in birth rate in the last fiscal year. Interior
Health Authority had the largest increase in birth rate in thelast year when compared to other Health Authorities at +5.0%.The Northern Health Authority had an increase in birth ratefrom 2004/2005 to 2005/2006 (+1.2%) and from 2005/2006 to2006/2007 (+0.8%). However, this increase was the smallestincrease in the province.
The Northeast Health Service Delivery Area experienced thelargest increase in birth rate in the last fiscal year at +12.4%(871 singleton births in 2005/2006 and 979 singleton births in2006/2007). Other HSDAs also experienced large increases inthe last fiscal year, such as East Kootenay (+8.8%), Okanagan(+7.1%), and Fraser East (+4.7%). Health Service DeliveryAreas that have had decreases in the last fiscal year includethe Northern Interior (-3.9%), the Northwest (-2.3%),Kootenay Boundary (-1.9%), and the South Vancouver IslandHSDA (-0.6%).
This analysis provides a preliminary examination of the birthrate changes in the province of BC. Further analysis of thedata would be beneficial to determine factors contributingto the disproportionate birth rate changes within the HAsand HSDAs.

Birth weight by gestational age groups were created by cate-gorizing the gender and gestational age according to birthweight percentiles. (Based on Appendix 4 and 5 birth weightand gestational age charts developed by BC Vital StatisticsAgency using 1981-2000 population as a standard). Newbornswere categorized as small-for-gestational age if they wereunder the 10th percentile for their gender and gestational age,large-for-gestational age if they were greater than the 90th per-centile, and average-for-gestational age if they were betweenthe 10th and 90th percentiles. Rates of these birth weight bygestational age groups were analyzed by place of residencefor both term and pre-term newborns and includes only sin-gleton deliveries.
Term (at least 37 completed weeks or 259 days gestation) sin-gletons born in British Columbia (BC) are increasingly average-for-gestational-age (80.8% in 2006/2007). Small-for-gestationalage in term newborns dropped slightly in the last fiscal year,from 7.0% to 6.8% of all term newborns. Similarly, large-for-ges-tational age in term singletons decreased, from 13.3% in2002/2003 to 12.4% in 2006/2007. The highest proportion oflarge-for-gestational-age term newborns was in VancouverIsland Health Authority at 15.6% in 2006/2007, followed closelyby the Northern Health Authority at 15.2%. The largest propor-tion of small-for-gestational-age term newborns in 2006/2007was in the Fraser Health Authority at 7.3%.
Over the last five fiscal years, a number of Health ServiceDelivery Areas (HSDA) in BC have seen an increase in the pro-portion of small-for-gestational-age term newborns. TheNortheast, Fraser East, Fraser North, and Thompson-Cariboo-Shuswap all have had slight increases in small-for-gestationalterm newborns while Kootenay Boundary had the largestincrease in BC, from 5.6% in 2002/2003 to 8.3% in 2006/2007.Conversely, the largest increase in large-for-gestational termnewborns was in the Coastal HSDA, where the rate increasedfrom 13.3% in 2002/2003 to 14.4% in 2006/2007.
Approximately 10% of preterm (less than 37 completed weeksor 259 days gestation) singletons born in BC are small-for-ges-tational age (9.4% in 2006/2007), while 13.4% of singletonpreterms in 2006/2007 are large-for-gestational-age. By HealthAuthority, the largest proportion of small-for-gestational agepreterms were in the Fraser Health Authority, increasing from9.7% in 2002/2003 to 11.6% in 2006/2007. Both the FraserHealth Authority and the Interior Health Authority have seenincreases in the proportion of small-for-gestational-agepreterms over the last five fiscal years. Large-for-gestational-age preterms were most prevalent in 2006/2007 in theNorthern Health Authority (17.4%), followed closely by theVancouver Island Health Authority (17.2%).
In 2006/2007, the Northwest Health Service Delivery Area(HSDA) had the highest proportion of large-for-gestational-agepreterms at 20.3%, although the North Vancouver IslandHSDA and the Central Vancouver Island HSDA followedclosely, with 18.7% and 18.5%, respectively. Small-for-gesta-tional-age preterms were most common in 2006/2007 in theFraser South HSDA (12.3%) and Vancouver HSDA (11.7%).

APPENDICES AND REFERENCES
AgeAge on date of event/age at last birth date preceding the event.
Age-Specific Fertility RateThe number of live births per 1,000 women in a specificage group.
AntepartumOccurring before birth.
BC Unspecified (Place of Residence)The postal code is unknown but it is known that the person isa resident of BC.
Birth weightFirst weight of the fetus or newborn obtained after birth, ex-pressed in grams. Low birth weight (LBW) birth weight is lessthan 2,500 grams. Very low birth weight (VLBW) – birthweight is less than 1,500 grams. (Excludes newborns withweight between 0-300 grams).
Care Provider for DeliveryPerson who provides the actual, hands-on care for the deliv-ery of the baby. The categories are: OB/GYN – includes obste-tricians (or fellow) and obstetrical residents; Family physician– includes general practitioners, and family practice resi-dents; Midwife – includes BC registered midwife and midwifetrainee; Nurse – includes nurses; Other/Unknown – includessurgeons, family members, ambulance attendants, medicalstudent intern (MSI), if there was no one in attendance or ifthere was no documentation.
Count of casesThe most basic measure is a simple count of cases or condi-tions of interest and is often expressed as a variable. Such fig-ures are important for strategic planning in health caresystems, especially in terms of resource allocation. Counts ofcases provide an idea of the number of people who will requirea specific treatment, intervention or service. The definition ofa variable is any attribute, phenomenon or event that can havedifferent values but is expressed as a single data element:• Yes, no, not applicable• A number (e.g., age)
Caesarean Section (C/Section) Method of DeliveryA delivery involving the surgical incision of the abdomen anduterine walls.
Electronic Fetal Monitoring (EFM)Mother received external or internal electronic fetal heart moni-toring during 1st or 2nd stage of labour. May include patients withelectronic fetal monitoring during latent phase of labour. Motherswho do not go into labour are classified as “Not Applicable”.
EpisiotomyA surgical incision into the perineum and vagina at the time ofbirth. If it is unknown if mother received an episiotomy, thiscase would be included in the category “No”.
FrequencyNumber of events or cases in a category.
Gestational AgeThe number of completed weeks a fetus has developed sincethe beginning of the pregnancy (gestation).
SGA – Small for Gestational AgeTerm used to describe babies who are born weighingless than the usual amount for the number of weeksof pregnancy. SGA babies have birth weights belowthe 10th percentile of a population specific weightversus gestational age plot.
AGA – Average for Gestational AgeTerm used to describe babies who are born withinthe normal range of weight for that gestational age.AGA babies have birth weights between the 10th and90th percentile of a population specific weight ver-sus gestational age plot.
LGA – Large for Gestational AgeTerm used to describe babies born weighing morethan the usual amount for the number of weeks ofpregnancy. LGA babies have birth weights greaterthan the 90th percentile of a population specificweight versus gestational age plot.

APPENDICES AND REFERENCES
Health Authority (HA)/Health Service Delivery Areas(HSDA) – DeliveryRefers to the Health Authority or Health Service Delivery Areain which the patient delivered. The BC Ministry of Health hasdefined six macro level administrative boundaries calledhealth authorities, which govern the manner in which healthcare services are delivered within the province of BC. HealthAuthorities are further divided into sixteen Health ServiceDelivery areas. HSDAs are micro level geographic boundaries.There may be more than one institution in a HA or HSDA.
Health Authority (HA)/ Health Service Delivery Areas(HSDA) – ResidenceRefers to the Health Authority or Health Service Delivery Areain which the patient resided at the time of delivery. Statisticsrelating to the client’s residence are determined via theTranslation Master File (TMF). The TMF file is a comprehen-sive demographic mapping file, which consists of valid BCpostal codes and their associated Health Service DeliveryAreas (HSDA) and Health Authorities (HA). The geographicarea to which a postal code belongs seldom changes overtime but in cases where the postal code has changed, appro-priate amendments have been made to reflect that postalcode’s associated HSDA for that particular year.
Home BirthBirth that occurred at home and mother was not admitted toan inpatient facility within 24 hours of the birth. The primarycare provider was a BC registered midwife.
Induction of LabourPatient who received instrumental or pharmacological assis-tance to promote labour, prior to the onset of first stage oflabour. A patient may be induced by any of the following meth-ods: artificial rupture of membranes (ARM), oxytocin,prostaglandin or other methodology. A failed medical inductionis classified as an induction. Induction is categorized as “un-known” if it is unknown how the patient’s labour was initiated.
Inductions performed prior to a delivery admission (e.g., asan antepartum admission or an outpatient visit) that have re-sulted in labour with subsequent admission are also classifiedas an induction.
Intermittent AuscultationA systematic method of listening to fetal heart tones with anacoustical device (fetascope) or hand-held ultrasound (dop-tone), paying attention to rate, rhyrthm and variability for atleast one full minute, most usually following a uterine con-traction (UC), and timing with a watch or clock with a sweepsecond hand.
Intrapartum (IP)The period between the onset of the first stage of labour andthe delivery of the placenta.
Late TerminationThe medical termination of a pregnancy beyond 20 weeks ofgestation. Gestation is measured in weeks and estimated fromthe first day of the last normal menstrual period.
Live BirthThe complete expulsion or extraction from the mother, irrespec-tive of the duration of the pregnancy, of a fetus in which there isbreathing, beating of the heart, pulsation of the umbilical cordor unmistakable movement of voluntary muscle, whether or notthe umbilical cord has been cut or the placenta is attached.
Maternal SmokingThere is documentation that the patient smoked during thecurrent pregnancy. If a patient smoked at any time duringpregnancy, even if she quit during the pregnancy, she is cate-gorized as a smoker in the current pregnancy.
Method of DeliveryVaginal
The complete separation of an infant from thematernal body via the vaginal canal.
Operative vaginal deliveryA vaginal delivery involving forceps or vacuum tofacilitate delivery of the fetus; includes vaginalbreech deliveries.
Caesarean sectionA delivery involving the surgical incision of theabdomen and uterine walls.

APPENDICES AND REFERENCES
Postpartum LOS – Vaginal/ Caesarean SectionLength of hospital stay calculated from delivery date/time todischarge date/time of mother, stratified into vaginal and cae-sarean births. This category excludes those who delivered athome with a BC registered midwife in attendance.
Preterm BirthLive birth after 20 and before 37 weeks completed weeks ofgestation.
ProportionA proportion is a measure of the number of persons having aspecific condition or intervention at a designated time. It isdefined as the number of existing cases divided by total pop-ulation from which those arose. It is reported as a percent, forexample, the percent of women giving birth in a specifichealth region, of all women in the region.
Rate“A rate is a measure of the frequency of occurrence of aphenomenon. In epidemiology, demography and vital sta-tistics, a rate is an expression of the frequency with whichan event occurs in a defined population; the use of ratesrather than raw numbers is essential for comparison of ex-perience between populations at different times, differentplaces or among different classes of persons. The compo-nents of a rate are the numerator, the denominator, thespecified time in which events occur and usually a multipli-er, a power of 10, which converts the rate from an awkwardfraction to a decimal or whole number”. (A Dictionary ofEpidemiology, 3rd Edition. John M. Last, Oxford UniversityPress, 1995)
StillbirthThe complete expulsion or extraction from the maternal bodyafter at least 20 weeks of gestation or after attaining a weightof at least 500 grams of a fetus in which at birth, there is nobreathing, beating heart, pulsation of the umbilical cord orunmistakable movement of voluntary muscle.
Term BirthLive birth after 37 completed weeks (or 259 days) of gestation.
Multiple reports can be accessed and various methods can beused to obtain BCPDR data in order to conduct analysis onperinatal processes and outcomes in British Columbia:
• Hospital Reports – these are hospital-specific, pre-pro-grammed reports, which can be run at all locations wherethe database is installed. Other participating sites, wherethe database is not installed, may obtain their specific hos-pital reports from the BCPDR central office.
• Ad hoc Reports – the database can be used to answer spe-cific requests through user-defined queries. These queriescan be developed and run at the hospital installation sitesor at the BCPDR central office.
• BC Facility Comparison Reports – these reports are creat-ed annually and allow the individual facility to compare andbenchmark selected maternal and newborn events and out-comes with provincial and similar sized sites.
• Perinatal Database Reporting Tool – The PerinatalReporting Tool is an interactive CD, which has been designedto allow health care providers, administrators and data ana-lysts access to summarized data sets extracted from the BCPerinatal Database Registry and is updated yearly. The PRTcan be used for analysis of population based and compara-tive reporting between institutions, Health Authorities andagainst provincial totals for some of the most commonand/or important practices and health outcomes related toperinatal care.
• Specific Requests for Data – clients, health care profes-sionals, researchers etc., may request specific data via theweb at <http://www.bcrcp.ca>. See Appendix 9.
