Abstract

Objective: Ultrasound is widely regarded as an important adjunct to antenatal care (ANC) to guide practice and reduce perinatal mortality. We assessed the impact of ANC ultrasound use at health centers in resource-limited countries.
Design: Cluster randomized trial.
Settings: Clusters within five countries (Democratic Republic of Congo, Guatemala, Kenya, Pakistan and Zambia).
Methods: Clusters were randomized to standard ANC or standard care plus two ultrasounds and referral for complications. The study trained providers in intervention clusters to perform basic obstetric ultrasounds.
Main Outcome Measures: The primary outcome was a composite of maternal mortality, maternal near-miss mortality, stillbirth, and neonatal mortality.
Results: During the 24-month trial, 28 intervention and 28 control clusters had 24,263 and 23,160 births, respectively; 78% in the intervention clusters received at least one study ultrasound; 60% received two. The prevalence of conditions noted including twins, placenta previa and abnormal lie were within expected ranges. 9% were referred for an ultrasound-diagnosed condition and 71% attended the referral. The ANC (RR 1·0 95% CI 1·00, 1·01) and hospital delivery rates for complicated pregnancies (RR 1·03 95% CI 0·89, 1·20) did not differ between intervention and control clusters nor did the composite outcome (RR 1·09 95% CI 0·97, 1·23) or its individual components.
Conclusions: Despite availability of ultrasound at ANC in the intervention clusters, neither ANC nor hospital delivery for complicated pregnancies increased. The composite outcome as well as the individual components were not reduced. This article is protected by copyright. All rights reserved.
