Abstract
Background Therapeutic inertia (TI), failure to intensify antihypertensive medication when blood pressure (BP) is above goal, remains prevalent in hypertension management. The degree to which self‐reported antihypertensive adherence is associated with TI with intensive BP goals remains unclear. Methods and Results Cross‐sectional analysis was performed of the 12‐month visit of participants in the intensive arm of SPRINT (Systolic Blood Pressure Intervention Trial), which randomized adults to intensive (120 mm Hg at the 12‐month visit (mean age, 69.6 years; 35.2% female, 28.8% non‐Hispanic Black), TI occurred in 50.8% of participants. Participants with low adherence (versus high) were younger and more likely to be non‐Hispanic Black or smokers. The prevalence of TI among patients with low, medium, and high adherence was 45.0%, 53.5%, and 50.4%, respectively. After adjustment, neither low nor medium adherence (versus high) were associated with TI (PR, 1.11 [95% CI, 0.87–1.42]; PR, 1.08 [95% CI, 0.84–1.38], respectively). Conclusions Although clinician uncertainty about adherence is often cited as a reason for why antihypertensive intensification is withheld when above BP goals, we observed no evidence of an association between self‐reported adherence and TI.
