A community-based obstetric ultrasound service

Area of Science:

• Obstetrics and Gynecology
• Medical Imaging
• Public Health

Background:

• Antenatal care in socioeconomically deprived areas presents unique challenges.
• Access to advanced diagnostic tools like ultrasound can be limited.
• Evaluating the impact of basic ultrasound services is crucial for resource allocation.

Purpose of the Study:

• To assess the effect of a community-based ultrasound dating service on obstetric care.
• To determine if a basic ultrasound service influences antenatal visit frequency and fetal surveillance referrals.
• To investigate the impact on perceived preterm labor, ruptured membranes, and post-term deliveries.

Main Methods:

• A prospective trial involving 3009 women in two South African Midwife Obstetric Units.
• One unit offered a basic ultrasound service by student ultrasonographers; the control unit had limited ultrasound availability.
• Primary outcomes included antenatal visits and referrals for fetal surveillance.

Main Results:

• Ultrasonography did not alter pregnancy outcomes but reduced perceived preterm labor/ruptured membranes (12.0% vs. 16.7%).
• Post-term deliveries were also reduced (8.1% vs. 10.8%).
• Referrals for fetal surveillance significantly decreased in the study group (15.9% vs. 29.6%).

Conclusions:

• A community-based basic ultrasound service effectively reduced referrals for fetal surveillance and delivery.
• This model demonstrates the value of accessible ultrasound in improving obstetric service efficiency.
• Basic ultrasound services can positively impact resource utilization in underserved areas.
