Abstract

Although poor control of hypertension is a problem worldwide, most published studies of adherence to antihypertensive medications have involved only white subjects. This study examined levels of and factors associated with short-term adherence to beta-blocker therapy among a representative sample of ethnic Chinese patients with hypertension from a large territory in Hong Kong. Data for all hypertensive patients aged > or = 18 years who received a prescription for a beta-blocker at a visit to any public primary care clinic in the New Territory East cluster of Hong Kong and made at least 1 subsequent visit for a refill of this prescription between January 2004 and June 2007 were obtained from a validated clinical database generalizable to the Chinese population. The proportion of patients who were adherent to beta-blocker therapy was measured based on the medication possession ratio (MPR), calculated over 2 consecutive visits. Good adherence was defined as an MPR > or = 80%. Factors potentially associated with adherence to beta-blockers were investigated using multivariable logistic regression analysis, with adjustment for age, sex, payment status, service type, district of residence, visit type, and number of comorbidities.
