Effect of USAID-funded obstetric ultrasound service interventions on maternal and perinatal health outcomes at primary healthcare facilities in Ethiopia: a propensity score matching analysis.

The findings show a consistent increase in maternal health service use because of the introduction of obstetric ultrasound services at the primary health centre level. Furthermore, early detection of complications and following referral for specialty care were found to be high. The consistent rise in maternal health service use indicators calls for additional trial to test the effect of obstetric ultrasound service in other locations of the country. Furthermore, evaluating the predictive values, sensitivity and specificity of the obstetric ultrasound service is important.
