This study aims to contextualize, implement, and evaluate the feasibility, fidelity, and acceptability and effectiveness of: 1) postpartum remote blood pressure monitoring, 2) patient education, 3) development of a standardized postpartum follow-up protocol, and 4) provision of free and/or subsidized antihypertensive medications for patients with HDP in University of Abuja, Murtala Muhammad Specialist Hospital, National Hospital, Abuja and Aminu Kano Teaching Hospital all in Nigeria. These components collectively make up a contextualized postpartum BP monitoring program called the HDP Implementation Bundle. The long-term objective is to implement a contextualized and acceptable evidence-based postpartum home BP monitoring program with supporting services and components, at 4 tertiary care institutions in Nigeria, to improve postpartum BP control in patients with HDP using a multilevel approach.
