IntroductionHypertensive disorders of pregnancy (HDPs) are a leading cause of maternal mortality and morbidity globally but could be mitigated through accurate and timely blood pressure (BP) monitoring. Self-monitoring of blood pressure (SMBP) in pregnancy is an emerging approach for the management of HDPs but mainly studied from the perspectives of pregnant women, in high-income contexts, or tertiary care. This qualitative study explored health workers' perspectives on SMBP by pregnant women, including through using a smartphone application, within primary healthcare settings of Lombok, Indonesia.MethodsWe conducted focus group discussions (FGDs) and in-depth interviews (IDIs) with community health workers, community-based midwives, facility-based midwives from primary healthcare centres, obstetrician/gynaecologists and health system managers (including heads of facilities, midwife supervisor and District Health Office administrators). Themes were grouped according to the normalisation process theory, which includes (1) coherence/understanding of the intervention, (2) cognitive participation/perceived value and (3) collective action/how the intervention will affect processes and organisational practices.ResultsWe recruited 68 participants across 8 FGDs and 26 IDIs. SMBP was perceived to improve timeliness of care and detection of high BP, but health workers expressed concerns about women's ability to accurately self-monitor, reliability and affordability of BP devices, and accountability and management of SMBP results. Embedding SMBP into routine antenatal care counselling, collaboration with family members, clarification on liability implications and protocols on SMBP follow-up actions, and use of digital communication channels were cited as potential ways to facilitate uptake of SMBP.ConclusionFor SMBP to be valued by health workers and effectively integrated into the health system as a strategy for addressing HDPs, it needs to be accompanied by clear clinical and data management protocols, referral mechanisms, reassurance on the accuracy and trust in the self-monitored measurements and demonstration of timeliness in the provision of follow-up care for pregnant women.
