Antenatal care (ANC) is a vital opportunity to provide integrated high-quality services that are essential for detection and case management of preventable causes of maternal morbidity and mortality. Hypertensive disorders of pregnancy (HDP), including pre-eclampsia and eclampsia, are a leading cause of maternal morbidity and mortality worldwide, yet can be prevented through early detection of blood pressure (BP) and timely evidence-based case management. Current approaches for checking BP are mediated by: i) access to functional and calibrated BP cuff and stethoscope, ii) health workers’ skills in performing BP measurement correctly, iii) ability to interpret readings and refer when necessary, and iv) diligence to manage clients throughout pregnancy. Partners WHO, Ona Kenya, and Biospectal will integrate and test, with partners in Tanzania (Ifakara Health Institute) and Indonesia (Summit Institute of Development), a cuffless smartphone BP measurement software (Biospectal OptiBP) within a robust digital longitudinal health record and decision-support system (OpenSRP software) that aligned with WHO ANC guidelines. This innovation facilitates accurate assessment and timely management of HDP, and improves correct action rates. OptiBP leverages smartphones existing hardware, disrupting traditional BP cuffs; embedding this software with OpenSRP facilitates decision-support, strengthens continuity of care, and drives effective use of clinical data for improving ANC quality. If successful at scale, the innovation could benefit ~215 million women annually who become pregnant globally, and has the potential to reach ~1.5 billion hypertensives who are at risk for noncommunicable diseases.
