This cross-sectional study extracted out-patient department (OPD) national, regional, and district-level aggregated surveillance data on hypertension from District Health Information System (DHIS2). These data are obtained from monthly outpatient report Health management information system (HMIS) forms. The study population was adults ≥ 18 years with hypertension from 2016 to 2021. Data were cleaned and analyzed using MS Excel and Epi Info. Logistic regression was used to assess trends of hypertension from January 2016 to December 2021. We described the spatial distribution of hypertension by region.
