Abstract
IntroductionAchieving hypertension control is beneficial regardless of age. Fixed-combination pills have the potential of increasing adherence to treatment, improving the benefit/risk ratio, and simplifying therapy, with resulting convenience especially in the elderly.AimWe examined real-world antihypertensive treatment adherence and hypertension control rates in a cohort of Italian elderly individuals, enrolled in a prospective, pragmatic awareness-raising campaign on blood pressure (BP).Methods13196 treated hypertensive elderly (mean age 73.2±7.5 years, 55.5% women) were recruited through opportunistic sampling, answered a brief questionnaire on antihypertensive therapy, and were followed-up for 6 months, when BP was measured as per routine care. Controlled hypertension was defined as BP < 140/90 mmHg. Real-world treatment adherence and hypertension control rates were evaluated at 6 months according to different treatment patterns (fixed-dose versus free combinations), using Yates correction for continuity to assess likelihood estimates for differences between treatments.Results10551 participants (80%) were on a single-pill therapy and 3445 were on a fixed combination therapy of two (24.8%) or three (1.3%) drugs. Individuals on a fixed combination therapy were more adherent to treatment than the counterparts (p < 0.001). Full adherence increased with the number of drugs/pill among single-pill users (47.5%, 68.5%, and 100% with 1, 2, or 3 drugs/pill; p < 0.001). Hypertension control rates were 70% and 65.2% (p = 0.001) according to fixed or free combinations of two drugs and 71% and 63.9% (p = 0.321) for fixed or free combinations of three drugs.ConclusionsReal-world data suggest that simplified treatment strategies and use of fixed combinations improve adherence to antihypertensive therapy and BP control in the elderly.
