Abstract
BACKGROUND
Prevalence of hypertension in Africa is rising but it remains underdiagnosed and poorly controlled. In Kenya, only 22% of individuals known to have hypertension were on treatment, and only 51.7% were controlled. This study will assess screening outcomes, retention and blood pressure (BP) control of a hypertension programme in Kenya.

DESIGN
This was a retrospective cohort study using data routinely collected between 2015 and 2018. All patients aged >18 years screened and treated in the programme were included.

RESULTS
Of 663,028 screening encounters, 70.4% were female; the median age was 34 years. Overall, 19% of the study population, mainly males and older persons, had high BP higher rates. Of 66,981 patients started on treatment, the majority were females (71.2%); the median age was 55 years. Only 12% of patients were reported as having been retained after 12 months, and 48.6% of patients on treatment 10.5-13.5 months after enrolment had controlled BP. Older age and treatment at primary care level were associated with better retention and females had better BP control.

CONCLUSIONS
The programme screened primarily females and younger individuals at lower risk. Retention was poor and close to half of patients retained had controlled BP. Hypertension programmes should target high-risk individuals, decentralise treatment, incorporate retention strategies and improve longitudinal data management.
