Background and Objective: In Bangladesh, 21% of all adults aged >=18 years have hypertension but among hypertensives, only 14.1% have blood pressure (BP) controlled (<140/90 mmHg) .1 To improve hypertension control and prevent cardiovascular disease, the Non-Communicable Disease Control Program under the Ministry of Health & Family Welfare launched the Bangladesh Hypertension Control Initiative (BHCI) with technical support from the National Heart Foundation of Bangladesh and Resolve to Save Lives. Method: The BHCI gradually implemented the World Health Organization (WHO) HEARTS standardized hypertension control package in 172 sub-district facilities (35% of all sub-district facilities) & 10 district-level facilities in 23 districts from 2018 to 2024. BHCI facilities implemented a simple, evidence-based, step-by-step, and drug & dose-specific hypertension treatment protocol, a reliable supply of protocol medicines free of charge to patients, team-based care including non-physician members, and the Simple digital hypertension management app to collect real-time data and facilitate patient and program monitoring over time. A continuous quality improvement initiated in 2020 focused on lowering missed visit rate and raising blood pressure control. Missed visit rate was the proportion of all enrolled patients failing to attend a scheduled clinic visit in the prior three months; BP control was proportion with BP <140/90 mmHg at their last visit in the prior three months. Results: From March 2019 to February 2024, the BHCI had enrolled 364,038 hypertensive patients in treatment (Figure). Facility-based BP control increased from 37% in July 2020 when the quality improvement program started to 57% by April 2024. Missed visits decreased from 53% in July 2020 to 29% by April 2024. Conclusion: BHCI is on track for national scale-up in Bangladesh and can serve as a model for WHO-HEARTS hypertension control programs in other LMIC countries. Reference: 1.
