Secondary data review was conducted. Participants included Inpatient diagnosed primary hypertensive patients 18 years and above across 14 regions of Namibia. The data source was District Health Information System 2 from which hypertension data from 2011 -2019 was extracted. Descriptive statistics, crude and age and sex standardized incidence rates (per 10,000 persons) within the primary clusters were calculated using   Stata version 15 and WinBUGS version 1.4.3. Models were fitted using Bayesian inference via Markov Chain Monte Carlo simulation methods with flat priors from overall incidence to estimate the incidence rates expressed as means.
