ABSTRACT
Effect of health education on anxiety of adult patient under going craniotomy.
Craniotomy is an elective neuro surgical procedure.Majority of people
have fear about surgery,post operative complication and out come. Many
studies have shown that pre operative health education reduce post operative
anxiety. Objectives of the study was to find out (1) effect of health education on
anxiety of adult patient undergoing craniotomy and (2) relationship between
anxity and selected variables such as age , sex , level of education , occupation,
and income. The study was conducted in Neuro surgical ICU and Neuro
surgical ward in SCTIMST ,Trivandrum. Sampling technique was alternate
sampling. The sample size was 34. Patients were randomly assigned to
Intervention (patients those seeking health education) and Control group (not
seeking health education). In this study the investigator used standardized
Malayalam version of Speilberger's State Trait Anxiety Inventory , for
assessing the anxiety. Two group pre test and post test design was used.
Individual health education using a self prepared pamphlet was given after
initial assessment. Major finding of the study was patients in the Intervention
group the State anxiety level was reduced both in male and female after surgery
compared than control group.The results support the existing knowledge that
pre operative health education reduces post operative anxiety.

INTRODUCTION
1.1 . INTRODUCTION
Craniotomy is the surgical opemng of the skull to gam access to
intracranial structures. This procedure is done to remove a space- occupying
abnormality such as tumor, cyst or vascular malformation. This procedure may
also be needed on an emergency basis to evacuate a hematoma ,relive
intracranial pressure and reverse a herniation syndrome. In this procedure, a
skull incision is made, the bone flap is elevated , dura is opened , and the tumor
is subjected to biopsy or resection. (Hickey, 2003).
Craniotomy is indicated for the diagnosis or treatment of intracranial
lesions demonstrated by neuroradiology , where there is adequate clinical .
indication with modem diagnostic facilities, truly exploratory procedures will
rarely be needed.
Contra - indication may be the nature of lesion, the speed of progression
symptoms and also the patients age and fitness. The few absolute
Page 13
contraindications include overwhelming infections or abnormalities of blood
coagulation. Poor neurological condition of the patient need to be a
contraindication, since surgical treatment of an intracranial mass will usually be
required before improvement can occur.
1.2. Background of the study
There are many reasons for performing a craniotomy. It may be done as
an emergency following a head injury or brain hemorrhage. This is to remove
blood clots, which are pressing on the brain. As a planned procedure , a
craniotomy may be essential to remove a tumor or to clip an aneurysm. All
operations carry some risks. Proper assessment of the postoperative status of the
patients requires an awareness of the patient's symptoms, so that a comparison
may be made between the pre operative and postoperative conditions. In case of
craniotomy the complications occurs intra -operatively, during the immediate
and late postoperative period. The complications after craniotomy includes
increased intra cranial pressure, vasospasm, cerebral infraction, hydrocephalus,
pneumonia, pulmonary embolism, diabetic insipidus, syndrome of inappropriate
anti diuretic hormone (SIADH) , wound infectios meningitis , seizure, cranial
nerve damage and functional disability. The late post operative complications
includes wound infections, seizure, meningitis, and functional disabilities . Most
2
Page 14
of the patients are very much anxious due to complications. So reduction of pre
operative anxiety is widely accepted as part of nursing care. (Johnson 1971).
SCTIMST is one of the major center in India where craniotomy is done
successfully. More than 100 cases were done in a month.
Johnson (1971) suggested that accurate pre operative information builds
accurate expectation of surgery which will infact reduce emotional arousal
during surgery. Anxiety is one of the most common emotions seen in health
care setting. Care of anxious client is one of the grater challenges as nurses.
Anxiety is a universal experience and an unavoidable aspect of everyone
life. Mainly anxiety is three types that are mild, moderate, and severe. The
responsibility for giving pre operative information o reduce anxiety is
recognized as a necessary and ongoing responsibility of the nurse as a source of
emotional support ( Oakely 1984)
Anxiety is one of the maJor problem in psychology and result in
considerable functional impairment. State and trait anxiety is one of the most
common features of anxiety. State anxiety refers to emotional reaction
characterized by subjective conscious feeling . of tension, apprehension,
nervousness and worry. In contrast , Trait anxiety deals with individual
difference in the dangerous, and in the frequency that state anxiety is
experienced. Statistics very widely but most agree that anxiety disorders are
3
Page 15
more common in women than in men. Medical illness and invasive procedure
are often associated with anxiety.
The most common used psychometric self-report inventory is probably
Speilberger's State Trait Anxiety Inventory (STAI - Speilberger's eta1.,1970
).State and Trait anxiety are analogus in certain respect to kinetic and potential
energy. People who differ in trait anxiety will show corresponding difference in
state anxiety depending on the extent to which each of them perceives a specific
situation as psychologically dangerous or threatening and this is greatly
influenced by each individual's past experienced.
1.3. Need and significance of study
Patients who are admitted for craniotomy are found to be more anxious
about the outcome of surgery . These patients also fear about the complications
and are in high emotional stress before surgery. The patient's anxiety level is an
indication of post operative problem . Pre operative anxiety increase the chance
of post operative pain, analgesic consumption, and hospital stay and recovery.
In this situation pre operative teaching plays an important role in
relieving anxiety and reducing anxiety related complications. The patients ask
too many questions about surgery, ICU staying, complications follow up
recovery etc. Hence the investigator felt the need to conduct the study about the
effectiveness of preoperative teaching on anxiety.

REVIEW OF LITERATURE
Review of literature is an important aspect of any research project from
beginning to end. It gives character insight in to the problem and helps in
selecting methodology, developing and also analyzing data. With these in view
an intensive review of literature has been done.
The review of literature relevant to this study IS presented m the
following section.
2.1 Studies for reducing anxiety by pre operative education.
2.2 Studies on craniotomy.
2.1 Studies for reducing anxiety by pre operative education.
Andrews et al;(l999) investigated the impact of treatment information
package on patients being monitored for possible surgical treatment for
temporal lobe Epilepsy.! 00 patients were randomly assigned to eighter a high or
low information preparation condition. Level of anxiety were tested soon after
admission. by using the Hospital Anxiety and Depression Scale (HADS). The
State -Trait Anxiety Inventory(STAI),and a newly devised questionnaire to
assess specific concern and anxieties of epilepsy patients presenting for
monitoring and surgery. Patients assigned to the high- information condition
8
Page 20
were exposed to an intervention package ,which included v1ewmg a video
depicting two separate interviews with patients who had undergone surgery as
vvell as an information package ,which described the various tests that the
patient would undergo in the course of the monitoring procedure . Patients
assigned to the low - information group were given information that the hospital
provided to all patients in there care. All subjects were then retested on anxiety
levels a few days later. Those in the high - information group showed a
significant in anxiety and depression levels compared with those in low
information group.
Sjoling et al; (2003) observed that specific information given prior to
surgery can help patients obtain better pain relief after total knee
arthroplasty(TKE). Objectives were to study the impact of pre- operative
information on state and trait anxiety,satisfaction with pain management and
satisfaction with nursing care. The study was an intervention study with two
group of equal size (n=30) . The intervention group was given specific
information , while control group received routine information. Pain
assessments were made pre operatively and first three post operative days using
Visual Analogue Scale(VAS). The result of this study suggested that
information influenced the experience of pain after surgery and related
psychological factors. The post operative pain declined more rapidly for
9
Page 21
patients in the treatment group, the degree of pre operative state anxiety was
lower and they were more satisfied with the post operative pain management.
Asilioglu and Celik ;(2004) the purpose of this experimental study was to
evaluate the effect of pre operative teaching method on anxiety levels of the
patients. This study consisted of 100 patients having open cardiac surgery.Of
1 00 patients 50 were interventional group and remaining 50 were in the control
group. The patients in the interventional group were given a planned teaching
according to the patient education booklet. Patients in the control group were
informed about only pre and post operative routine, by the purpose . of
comparing anxiety level of the patients in the interventional group and control
group. Anxiety of both group were measured on the 3rd day after the operation
by using Self Evaluating questionnaire for state and trait anxiety inventory
scale. The mean post operative state and trait anxiety score in the control group
was slightly higher than the mean ofthe patients in the intervention group.
Deyirmenjian et al ; (2006) assessed the impact of pre operative patients
education on anxiety and recovery of patients undergoing open heart surgery.
This quasi- experimental study the patients were randomly assigned to a
experimental (n=57) on a control group (n=53) group. The patients in the
experimental group received special education and the control group followed
the routine hospital protocol. Anxiety was assessed using the Beck Anxiety
Inventory Scale (BAIS).Borderline statistical significance was noted for the
10
Page 22
experimental group in terms of pre operative and post operative anxiety. It is
also reported that the experimental group had a shorter time from awaking to
extubation.
Vanzurren et al ; (2006) studied the potential beneficial effect of an
information brochure on patients undergoing a gastrointestinal endoscopy for
the first time. Patients were randomly assigned to an experimental group
receiving the brochure at least 1st day before the gastroscopy (n=4 7) , or control
group not receiving the brochure (n=48) . The result showed that all
experimental sujects , those receiving the brochure experienced less anxiety
before the gastroscopy and after wards they reported grater satisfaction. Low
bunters (those not seeking information) as compared to high blunters showed
extra reduced anxiety after reading the brochure. High moitores (those seeking
information) receiving the brochure showed reduced anxiety during the
gastroscopy as compared to low monitores.
Nemi-Murola et al ; (2007) studied about patients often suffer from
inadequate treatment of post operative pain. The purpose of this study was to
survey the factors affecting patients · satisfaction with post operative pain
management . A questionnaire with 41 items given on the 3rd postoperative day
to 102 patients undergoing major orthopedic or vascular surgery. Intensity of
pain was assessed using a 10-cm visual analogue scale (VAS) and given
analgesics were recorded. Nurse (n=74) working on the ward received a
11
Page 23
questionnaire concernmg attitudes towards management of pam. The
questionnaire were returned by 75.5% of the patients and 86.3% of the nurses.
28% of the patients agreed having hard pain during the day of operation and
39.3% during the 1st post operative night. 80% of the patients were satisfied
with pain management their satisfaction correlated significantly with received
the pre operative information. Pre operative interview is very important tool to
receive and give information concerning post operative pain management.
Beapupre et al ; (2004) observed that the effectiveness of a pre operative
exercise\ education program following primary total knee arthroplasty (TKE) .
I 31 subjects were randomized to either the control (n=66) or treatment (n=65)
group 6weeks before TKE surgery. Patients in the treatment group underwent a
4 week exercise \educational program before surgery. All subjects were
assessed 6 weeks pre operatively (before the exercise \education intervention)
immediately pre operatively (after the exercise \education! intervention) ,and
3,6andl2 months after surgery utilizing the western Ontario McMaster
osteoarthritis Index. Subjects were similar in demographic characteristics and
all measures at the baseline assessment.
Davis et al ; (1994) to examine the effects of coping style and type of
preparatory informational treatment on cardiac catheterization patient anxiety.
Pre test - post test randomized control group design. 145 adult patients (107
men and 38 women) scheduled for their first cardiac catheterization. Age range
12
Page 24
was from 34 to 78 yrs. Patients randomly assigned to monitoring (information
seeking) or blunting (information avoiding ) . Subject's coping style was
assessed by mans of Miller's Behavioral Style Scale. Subjects anxiety was
assessed by means of Speilberger's A-Trait and A-State Inventory.Sbjects
anxiety was assessed before and after intervention (timel&time2) and before
and after catheterization (time3& time4) . Monitors who received the procedural
--sensory modeling video treatment and blunters who received the procedural
modeling video treatment reported significant reductions in A-State anxiety .At
time 4 monitors and blunters in each of the treatment group reported a
significant decrease in A-State anxiety. Female monitors and blunters reported
significantly higher A-State anxiety level than male .
Blay and Donoghue (2005) observed the objectives of randomized
controlled study were to determine if pre admission patients education affects
post- operative pain levels , domiciliary self care capacity and patient recall
following a laproscopic cholecystectomy (LC) .Sampling is 93 elective
Lcpatients. Participents were randomized to receive the standard pre admission
program (SP) or an individualized , education intervention (EI). A pre -
operative questionnaire was administered in the pre admission clinic to
determine participants' knowledge of LC and post operative management.
Telephone follow-up and postoperative questionnaire were conducted
approximately 14 days post discharge. EI participants experienced lower pain
13
Page 25
levels and significantly grater recall of provided information . However no
significant difference were found between the control and intervention group for
domiciliary self-care. Pre education intervention helps reduce post operative
pain levels following LC and significantly increases patients' knowledge of self
care and complication mnagement.
Lilja et al ; (2003) evaluate the effects of extended pre operative
information , given by anesthetic nurses, on pre operative stress in patients
operated on for breast cancer or total hip replacement (THR) .46 consecutive
patients scheduled for surgery for breast cancer and 55 for THR , were
randomized in to two groups which were given different modes of pre operative
information . Patients in the controlled group were informed about pre and post
operative routine by ward nurse . Patients in the intervention group were given
extend formalized information by an anesthetic nurse . Wilcoxon rank sum test
was used to show relations between variables . There were no significant
differences between the intervention group and control group for patients with
breast cancer or for the patient with THR . Breast cancer patients in the
intervention group were significantly more anxious than THR patients in the
intervention group (p<O.Ol). Breast cancer patients in the intervention group
showed the highest anxiety scores on the Hospital Anxiety and Depression
Scale (HADS) on the day of surgery . This information may reflect an increased
level of anxiety due to the extend information given pre operatively . The
14
Page 26
information may have negative effect on breast cancer patients , resulting in an
increased state of anxiety.
2.2 Studies on Craniotomy.
Brackmann et al ; (2007) conducted a to evaluate the long-term facial
function of patients after translabyrinthine vestibular schwannoma [VS] surgery
and identify factors that influence these outcomes. A retrospective review was
performed that included 580 consecutive patients who underwent
translabyrinthine craniotomy for removal of VS. A total of 512 patients who
underwent primary microsurgical treatment of sporadic unilateral VS met
inclusion criteria. Patient and tumor characteristics as well as perioperative
complications are described. Perioperative and long-term facial function were
evaluated in 392 patients who had at least 1-year follow-up. Complication rates
after translabyrinthine craniotomy for VS are low. Patients with smaller tumors
have significantly better postoperative facial function than those with larger
tumors. Excellent long-term facial function can be expected in the majority of
patients who undergo microsurgical removal of VS via the translabyrinthine
approach. Alternative treatment strategies may need to be developed for the
treatment ofVS > 3.5 em in orderto maximize postoperative facial function.
Kourbeti et al ; (2007) conducted a retrospective cohort study to
determine the incidence, bacteriological features, and risk factors for
postcraniotomy meningitis. Patients older than 18 years who underwent
15
Page 27
nonstereotactic craniotomies between January 1996 and March 2000 and who
survived for more than 7 days were included. Operations for placement of burr
holes and shunts were excluded. Records of the first 30 postoperative days were
abstracted. Host factors, types of craniotomy, and pre- and postoperative
variables were evaluated as risk factors for meningitis. Among 453 patients,
there were 25 cases of meningitis. Eight out of 12 culture-positive cases were ·
the result of gram-positive cocci. 420 (92%) patients received antibiotic
prophylaxis, most commonly a first-generation cephalosporin. In multivariate
analysis, the risk of meningitis was increased by surgery that entered a sinus ,
and increases in the number of days of external ventricular drainage and
intracranial pressure monitoring. Access of upper airway bacteria to the surgical
wound, host factors as expressed by the American Society of Anesthesiologists
score, and duration of device-related postoperative communication of the
cerebrospinal fluid and the environment are major risk factors for postoperative
meningitis after craniotomy.
Curry et al ; (2005) conducted a study was to determine the risk of
adverse outcomes after contemporary surgical treatment of meningiomas in the
US and trends in patient outcomes and patterns of care. The study were
performed a retrospective cohort study by using the Nationwide Inpatient
Sample covering the period of 1988 to 2000. Multivariate regression models
with disposition end points of death and hospital discharge were used to test
16
Page 28
patient, surgeon, and hospital characteristics, including volume of care, as
outcome predictors. Multivariate analyses revealed that larger-volume centers
had lower mortality rates for patients who underwent craniotomy for
meningioma. Adverse discharge disposition was also less likely at high-, and a
significantly less frequent adverse discharge disposition. In-hospital mortality
rates decreased 61%, from 4.5% in 1988 to 1.8% in 2000. Reductions in the
mortality rates were largest at high-volume centers (a 72% reduction in the
relative mortality rate at largest-volume-quintile centers, compared with a 6%
increase in the relative mortality rate at lowest-volume-quintile centers). The
number of US hospitals where craniotomies were performed for meningiomas
increased slightly. The mortality and adverse hospital discharge disposition
rates were lower when meningioma surgery was performed by high-volume
providers.
Mark Bernstein ; (200 1) observed that routinely performed awake
craniotomy for intra-axial brain tumors with low complication rate and low
resource utilization. A pilot study was initiated to assess the feasibility of
performing craniotomy for tumor resection as an outpatient procedure. A
rigorous protocol was developed and adhered to, based around the patient's
arrival at hospital at 6:00 am, undergoing image-guided awake craniotomy with
cortical mapping, and being discharged by 6:00 p.m. During the 48 month
period from December 1996 to December 2000, 245 awake craniotomies were
17
Page 29
performed and of those, 46 patients were entered into the outpatient craniotomy
protocol. Pathology in the 46 intent-to-treat group was: 21 metastasis, 19
glioma, and six miscellaneous. Four patients required conversion to inpatients
and one patient was readmitted later the same evening due to headache. Thus
41146 patients successfully completed the protocol (89%). There were five
complications in the 46 intent-to-treat group (10.9%). Outpatient craniotomy for
brain tumor is a feasible option which appears safe and effective for selected
patients, the procedure may be psychologically less traumatic to patients than
standard craniotomy for brain tumor.

3.3 Settings:
The study was conducted in the Neuro surgical ICU and Neuro surgical
ward at SCTIMST; Trivandrum. The rationale for selecting this hospital was
that this is one of the superspeciality hospital in India doing craniotomy. In this
hospital on an average, 100 craniotomy cases are done every month on a regular
basis. More over, the investigator was familiar with this hospital.
3.4 Sample and sampling technique:
Alternate sampling technique was used for selecting the sample. All the
patients who met the inclusion criteria were selected. The total duration of the
study period was September- October 2008.
3.5 Inclusion criteria :
• Both male and female patients undergone craniotomy.
• Those patients who are co operative, conscious and oriented.
• Those patients who know Malayalam.
3.6 Exclusion criteria :
Children below the age of 18 yrs.
3. 7 Development of tool
An extensive review and study of literature helped in preparing a health
education pamphlet and it was scrutinized and approved by experts in Sree
20
Page 32
Chitra Thirunal Institute Of Medical Science and Technology. In this study the
investigator used standardized Malayalam version of Speilberger's State Trait
Anxiety Inventory of assessing pre operative anxiety and to assess post
operative anxiety which contain 36 questions.
3.8. Description on tool :
The tool used in present study consists of the following parts:
Part -1
This part contains demographic data including age, sex, education, occupation
and income.
Part -11
It consists of Speilberger' s State Trait Anxiety Inventory which is popular
instrument for measuring anxiety. It has been. used previously in many
researches to assess emotional reaction to surgical procedure. This inventory
. consists of 36 self reporting items and has two parts. The State anxiety and Trait
anxiety.
Part -111
Patients were randomly assigned to experimental and intervention group.
After assessing the anxiety level, health education was given to the intervention .
group. The health education pamphlet contains details about the disease
condition,Surgery, need for surgery and ICU stay.

3.7 Pilot study :
Pilot study was conducted from September 15th to 25th, 2008. The aim of
the study was to assess the effect of health education on anxiety of adult patients
undergoing craniotomy. The study was conducted among five patients, both
male and female between the age group of 18 to 60 yrs. The tool used is State
Trait Anxiety Inventory (STAI) with 36 questions. The questions were asked in
Malayalam. Total time period required was 30 minutes for a patient. Pilot study
reveled that post test anxiety score was lower than pre test anxiety. After
making necessary correction in the scoring part of the tool the main study was
conducted.
3.8 Data collection :
For data collection formal permission was obtained from the authorities. Period
of data collection from September 2008 to October 2008. Data was collected
from patients in the Neurosurgical ward and Neurosurgical ICU.
The investigator first introduced herself and explained need and purpose study
to the patients. After getting consent from the patients, anxiety level of the
patients was assessed with the help of Speilberger's State Trait Anxiety
Inventory. After this health education was given to patients in the intervention
group by using self-preparing health education pamphlet. The patients were also
given the opportunities to clear their doubts. In case of experimental group
22
Page 34
health education is not received. On the 1st post operative day, both groups
(Intervention and control group) anxiety were assessed by using the same
structured anxiety scale, to find out the effectiveness of health education in
reducing the anxiety level .
3.9 Plan of analysis :
A plan of data analysis was developed by the investigator after the pilot
study. A master sheet was prepared with the score obtained in the STAI.
(Descriptive statistics is used to analyses the data).
3.10 Summary :
This chapter deals with research approach, the study design, setting of the
study, sample and sampling technique, development of tool, data collection
and plan of analyze.

CHAPTER IV
Analyse and interpretation of data
This chapter presents the analysis and interpretation of data collected
from 34 patients who underwent craniotomy at SCTIMST , Trivandrum.
Analysis is a process of organizing and synthesizing in such a way that project
elicit meaning from collected data. The aim of the research study was to assess
pre operative anxiety of patients undergoing craniotomy and to assess the effect
of pre operative teaching on the anxiety level of patients undergoing
craniotomy.
Interpretation refers to the process of making sense of the results and of
examining the implication of the findings with in a broder content.
The data were coded , entered in Microsoft excel and analysed using epi info
version 3.2 .
The finding of the study were arranged and analyzed under the following

SUMMARY , CONCLUSION , DISCUSSION AND RECOMENDATION
A brief account of the study is given in this chapter which cover objectives,
findings of the study, and possible application of the result. Recommendations
for future research and suggestions for improving the present study are also
presented.
5.1 . Summary
The study was conducted with the objectives to assess pre- operative
anxiety before health teaching and and to assess post - operative anxiety. The
structured State-Trait Anxiety Inventory was for collecting data from 34
samples.
A review of related literature helped the investigator to get a clear
concept about the project topic undertaken , as well as to develop tools,
methodology of the study and decide the plan for data analysis.
A standardized Speilberger's State Trait Inventory was used for assessing
the anxiety level of the patients with a standardized questionnaire , health
education on surgery, ICU stay, complication and outcome was given.
35
Page 47
The study was conducted in SCTIMST , Trivandrum ,during the period
of Sep - Oct 2008. The sample comprised of 34 patients, both males and
females. Between the age group of 18 -75 years. Tool used for data collection
patients demographic data, Speilberger's State Trait Anxiety Inventory. State
anxiety scale consisted of 18 questions and Trait anxiety scale consisted of 18
questions.
5.2. The major findings of the study
The study results showed that there was a statistically significant
reduction in the mean post state craniotomy anxiety of the samples .
5.3. Limitation
1. Study was limited to the SCTIMST ,Trivandrum
2. Study was conducted in a single group of patients admitted for craniotomy.
3. The study was conducted only among patients who could read Malayalam.
5.4 . Discussion
Assessment of anxiety level of patients who undergoing craniotomy is
very impmiant , because these patients are anxious about surgery, ICU stay ,
complication, outcome etc.
According to Andrewes et al ; (1999) Asilioglu and Celik (2004)
VanZuuren et al ; (2006) Nemi-Murola et al ;(2007) pre operatively patients had
36
Page 48
higher level of anxiety than post operatively. The findings of the present study
is comparable to these results. The present study showed that health education
seemed to decrease the anxiety level post operatively
5.5. Recommendations
The following recommendations are made on the basis of present study.
• Similar study can be reported by increasing the sample size.
• True experimental study to assess the effectiveness of pre operative
teaching on anxiety level of patients before and after surgery can done.
5.6 . Conclusion
Based on the findings of the study , the following conclusion were drawn.
With this limited number of patients it is not possible to generalize
findings.
There is need for study studies involving more number ofpatients
validate the findings.
