Abstract
OBJECTIVES
Hypertension is a leading cause of death and disease burden followed by dyslipidemia. Their asymptomatic nature leads to low adherence and persistence to treatments. A systematic literature review (SLR) investigated the impact of single-pill-combinations (SPC) compared to free-equivalent combination (FEC) on adherence, persistence, clinical outcomes, healthcare resource utilization (HCRU), and patient-reported outcomes, in patients with hypertension, dyslipidemia, or both.
METHODS
MEDLINE, MEDLINE-IN-PROCESS, Embase, and Cochrane were searched from inception until 11 May 2021, for studies comparing SPC against FEC in patients with hypertension and/or dyslipidemia. Patient characteristics, study design, therapies, measures of adherence or persistence, clinical outcomes, and follow-up were extracted.
RESULTS
Among 52 studies identified in the SLR, 27 (n = 346,030 patients) were included in the meta-analysis. SPCs were associated with significantly improved adherence compared with FEC, as assessed through medication-possession-ratio ≥80% (odds ratio (OR) 0.42, p < 0.01) and proportion of days covered ≥80% (OR 0.45, p < 0.01). SPC also improved persistence (OR 0.44, p < 0.01) and systolic blood pressure (SBP) reduction (mean difference -1.50, p < 0.01) compared with the FEC.
CONCLUSIONS
SPC use resulted in significantly improved adherence, persistence, and SBP levels compared with FEC in patients with hypertension. The findings support SPC use in reducing the burden of hypertension and dyslipidemia.
