  "summary_plain": "WHO's HEARTS technical package is a set of modules for managing high blood pressure and other cardiovascular risk in primary health care. WHO lists six modules and an implementation guide: healthy-lifestyle counselling, evidence-based treatment protocols, access to essential medicines and technology, risk-based cardiovascular disease management, team-based care and systems for monitoring. WHO says a detailed, standardized treatment protocol is a critical first step in a large-scale hypertension programme. In a matched-pair trial in rural Bangladesh, clinics using the package had lower blood pressure and better control at 6 months than usual-care clinics.",
  "summary_technical": "The WHO publication page dates the package 27 December 2016 (76 pages, ISBN 9789241511377). WHO's 2023 Global report on hypertension says the package was launched in 2018 as the core technical package of the Global Hearts Initiative. The two dates are given as the sources state them and are not reconciled. This record did not read the module PDFs; the module list comes from the WHO publication page and the 2023 report. The one evaluation recorded is a quasi-experimental trial, not a randomized one.",

      "statement": "A matched-pair cluster quasi-experimental trial in 14 Upazila Health Complexes (primary healthcare facilities) in rural Bangladesh compared 7 clinics implementing the WHO HEARTS technical package with 7 matched clinics continuing usual hypertension care. It enrolled 3935 patients (mean age 52.3 years, 70.5% female) with uncontrolled hypertension (blood pressure of 140/90 mm Hg or higher regardless of treatment history): 1950 from the HEARTS clinics and 1985 from the usual care clinics. At 6 months, 95.5% of participants completed follow-up. Compared with usual care, the intervention lowered systolic blood pressure (-23.7 mm Hg against -20.0 mm Hg; net difference -3.7 mm Hg, 95% CI -5.1 to -2.2) and diastolic blood pressure (-10.2 mm Hg against -8.3 mm Hg; net difference -1.9 mm Hg, 95% CI -2.7 to -1.1), and improved hypertension control (62.0% against 49.7%; net difference 12.3%, 95% CI 9.0 to 16.8). The rate of missed clinic visits was lower in the intervention group (8.8% against 39.3%, p<0.001).",

The primary outcome was systolic blood pressure at 6 months, measured at the patient's home. Severe flooding affected both groups towards the end of follow-up, and follow-up was extended by 2 months where needed. The intervention group was more affected: more of its patients reported the flood prevented them from attending 1 or more clinic visits (30% against 8%) and from getting a medication refill (27% against 9%). The paper planned a sample of 2100 and kept enrolling after reaching it. The registry's primary completion date (2021-12-31) is earlier than the 6-month follow-up the paper describes; the two are not reconciled here. The result is for rural primary care clinics in one country.",
