[Practice of home blood pressure monitoring in a population of hypertensive patients in subsaharan Africa]

Abstract

Aim: To investigate home blood pressure monitoring (HBPM) practice among treated hypertensive patients in a subsaharan Africa setting.

Patients and methods: Cross-sectional observational study over a five-month period from April 30 to September 30, 2019. The survey was carried out among treated hypertensive patients aged at least 18-years-old, received in outpatient consultations department at the Abidjan Heart Institute during the study period. We assessed the rate of patients performing HBPM, and compared characteristics and rate of blood pressure control between patients according to the realization of HBPM.

Results: Three hundred hypertensive patients (mean age 59.2±12.0 years, sex ratio 1.4) were included. Of these, 68.3% reported to have information about HBPM. In 42.3% of cases, patients had an electronic blood pressure device at home, the majority of which were devices with arm cuffs (65.3%). The study showed that 40.3% of the patients had received education on hBPSM, most commonly provided by practitioners (71.9%). Among our population study, 36.3% performed HBPM, of whom only 13.8% according to the 3-day standardised protocol. In multivariate analysis, HBPM appeared to be an independent factor associated with better blood pressure control.

Conclusion: HBPM is rarely used by patients with hypertension in our practice. Most of the patients do not receive education about HBPM and adequate training in order to perform it routinely.
