Intrauterine growth restriction (IUGR)?

Background

• Significant complication of pregnancy globally• Significant implications for maternal, infant,

child and later health• Most cases occur in pregnancies with no risk

factors• Single most important component of stillbirth

statistics• Routine growth screening strategies failing

Recent reports

• Under-diagnosed complication of pregnancy

• Inadequate monitoring of growth

• Failure to recognise IUGR

• Failure to act on IUGR

Study aims

• Describe current practice

• Explore experience and preferred clinical practice

• Identify potential barriers, training or practice needs

Methodology

• Mixed methods approach

• Ethical approval and Health & Social Care Trust indemnification

• Study population

Setting

Phase 1: • Semi-structured interviews• a regional maternity unit in Northern Ireland

Phase 2:• Survey• All maternity units in Northern Ireland

Sample selection

• Midwives:providing antenatal care

• Obstetricians:working in obstetrics &

gynaecology

Contact made through Heads of Midwifery and Clinical Directors

Phase 1

• Semi-structured face-to-face interviews

• Transcribed verbatim

• Content analysis

Results: response data

Phase 1:11 midwives5 obstetricians

Working in large regional maternity unit in NI

Results (part 1)

Themes emerging for detection of IUGR include:

• confidence and accuracy in detection of IUGR

• consistency and continuity

• skills/training

Results (part 1)

Themes emerging for management of IUGR include

• referral

• further assessment and decision-making

• suggested strategies for detection and

management of IUGR

Sample selection

Phase 2:767 midwives208 obstetricians

Providing antenatal care in all maternity units (n= 10) throughout Northern Ireland (NI)

Survey

Main components:• Demographics• Current practice• Experience• Preferred clinical practice• Identify potential barriers, training or practice

needs

Results: response data

Phase 2:198 midwives66 obstetricians

Conclusions

• Variance in tools used to assess fetal growth and wellbeing

• Variance in agreement how sensitive these tools are in detecting IUGR

• Variance in level of confidence in using these tools

• Training considered very important in terms of successful implementation of these tools

Conclusions (2)

• Less than 60% confident in their clinical skills to detect and manage IUGR

• Room for improvement with regards identification and management of babies at risk

• Evidence suggests many consequences of IUGR could be prevented by improved detection, appropriate surveillance and timely intervention

Challenge to identify those babies at risk

Implications for practice

• findings challenge current practice amongst midwives and obstetricians in the detection and management of IUGR

• highlights the importance of the multidisciplinary team in ensuring optimal care for these women and their babies
