Abstract

Objective To determine the prevalence of uncontrolled blood pressure and its associated factors in hypertensive patients. Method This study collected the data of hypertensive patients attending medication refill clinic and general clinic with diagnostic codes I10-I15 the electronic database of a 500 bed general hospital from February 1, 2018 to January 31, 2020. Factors hypothesized to have an association with uncontrolled blood pressure included socio-demographic factors, health and medications factors. Result A total of 7,849 patients participated in the study, with 94 in medication refill clinic and 7,755 in general clinical. The prevalence of uncontrolled blood pressure 79.40%. 73.40% of those in medication refill clinic and 79.5% of those in  general clinical could not control their blood pressure. From the data on blood pressure measured from February 1, 2018 to January 31, 2020, four factors were significantly associated with uncontrolled blood pressure. Male, a larger body mass index (BMI), and the higher number of antihypertensive medications were associated with an increased risk of uncontrolled blood pressure. Having cardiovascular disease as comorbidities was associated with a decreased risk of uncontrolled blood pressure. Conclusion: Male patients, those with BMI greater than 18.4 kg/m2, and those receiving more than one antihypertensive medicine should be carefully scrutinized before referring them to medication refill clinic because these groups of patients are at risk of uncontrolled blood pressure.
