Absolute Event Rate: 41.8% vs 28.1%
Self-report questionnaires are feasible for detecting non-adherence to antihypertensives in community pharmacies, though in-person interviews may underestimate non-adherence compared to mailed surveys.
Ude et al. (2012) conducted a cross-sectional in Hypertension (n=677). Short form (SF) mailed questionnaire vs. Long form (LF) pharmacist interview was evaluated on Self-reported adherence problems. A mailed short-form questionnaire detected adherence problems in 41.8% of patients taking antihypertensives, compared to 28.1% detected by a long-form pharmacist interview.
