Perinatal mortality rates in isolated general practitioner maternity units.

Area of Science:

• Obstetrics and Gynecology
• Perinatal Health
• Public Health

Background:

• Perinatal mortality rates vary significantly based on the intended place of delivery.
• Understanding these variations is crucial for improving maternal and infant outcomes.

Purpose of the Study:

• To determine the perinatal mortality rate in a rural health district.
• To analyze these rates based on the intended place of delivery for normally formed singleton babies weighing ≥2500g.

Main Methods:

• Retrospective analysis of 14,415 deliveries in Bath health district.
• Data collected via monthly returns from maternity units, including live births, stillbirths, and infant deaths within 7 days.
• Intended place of delivery confirmed at monthly perinatal mortality meetings.

Main Results:

• Perinatal mortality rates: 2.8/1000 (consultant unit), 4.8/1000 (isolated GP units), 0/1000 (integrated GP unit).
• Asphyxia-related deaths were more common in isolated GP units (1.5/1000) than consultant units (0.6/1000).
• Parity did not significantly influence perinatal mortality rates across different units.

Conclusions:

• Higher perinatal mortality in isolated GP units is linked to antenatal and intrapartum care deficiencies.
• The integrated GP unit demonstrated positive outcomes, possibly due to shared staff with the consultant unit.
• Recommendations include enhanced training for general practitioners and improved consultant supervision of antenatal care in isolated units.
