Can elderly patients over 60 years of age achieve high compliance with an antihypertensive treatment regimen?
Elderly patients, including those over 80 years of age, can achieve and maintain high levels of compliance (80-90%) with antihypertensive medications over a 1-year period.
Assessing the compliance of people over 60 years of age and older with an antihypertensive treatment regimen was a major objective of the Systolic Hypertension in the Elderly Program (SHEP) pilot study. The study randomized 551 men and women over the age of 60 (mean age = 72 years) to a stepped care treatment that included chlorthalidone or placebo in a double-blind trial. Three measures of compliance to treatment protocol--pill count, self-report, and a urine chlorthalidone assay--all indicated high levels of compliance in 80 to 90% of participants at 3 months and 1 year after randomization. Pill-taking compliance was similar in the active and placebo groups, although the rate of discontinuance from study medications at 1 year was higher in the placebo than in the active group. Compliance was high in all age categories, including those over age 80. These data suggest that elderly patients can achieve high levels of compliance with antihypertensive medications.
