Controlled trial of a Preterm Labor Detection program: efficacy and costs

Area of Science:

• Obstetrics and Gynecology
• Maternal-Fetal Medicine
• Public Health

Background:

• Preterm birth remains a significant challenge in maternal-fetal medicine.
• Patient education and frequent clinical evaluations are proposed strategies to reduce preterm births.
• The effectiveness of targeted preterm labor detection programs requires further investigation.

Purpose of the Study:

• To evaluate the efficacy of a comprehensive patient education and weekly clinical evaluation program for detecting and managing preterm labor.
• To assess the impact of a Preterm Labor Detection Clinic on gestational age at delivery, birth weight, and preterm birth rates.

Main Methods:

• A prospective study involving 943 indigent, inner-city women over 3.5 years.
• Utilized the Papiernik-Creasy scoring system to identify high-risk pregnancies.
• Randomized high-risk women to a Preterm Labor Detection Clinic or standard care; low-risk women served as controls.

Main Results:

• No significant differences in mean gestational age, mean birth weight, or preterm birth rates between the high-risk intervention and control groups.
• Outpatient clinic utilization and charges significantly increased for the intervention group.
• High rates of premature rupture of membranes (PROM) and fetal death were observed across all study groups.

Conclusions:

• The intensive outpatient preterm labor detection program did not effectively reduce preterm births or improve key neonatal outcomes.
• The program's failure may be linked to a low incidence of women presenting with advanced cervical dilation in preterm labor.
• Further research is needed to identify more effective strategies for preventing preterm birth and its complications, such as PROM and fetal death.
