Abstract

Aims: This study aims to identify the interventions used to improve adherence in patients receiving statins for primary prevention of cardiovascular disease and to determine the effectiveness of these interventions. Methods and results: This systematic review and meta-analysis was conducted according to PRISMA guidelines. The protocol was registered with PROSPERO (CRD42024587573). Search was performed in MEDLINE (PubMed), SCOPUS, EMBASE, and CINAHL for studies published between January 2000 and May 2024. Thirty-four studies with five intervention strategies met the eligibility criteria, of which 18 were non-cluster randomized controlled trials (ncRCTs), 10 were cluster RCTs (cRCTs), and 6 were non-randomized studies of interventions (NRSI). The intervention strategies were multifaceted, education-based, behaviour change/monitoring, regimen modification, and incentive-based. Meta-analysis showed that the pooled risk ratio (RR), relative to control, for ncRCTs was 1.12 (95% CI: 1.00–1.25); for cRCTs, it was 1.50 (95% CI: 0.97–2.31); and for NRSIs, it was 1.37 (95% CI: 0.95–1.98), with point estimates in favour of the intervention arms. High heterogeneity was observed across studies, with I2 > 91%. Subgroup analysis suggested that relative to controls, there was a potential benefit of digital components in both ncRCTs (RR = 1.08, 95% CI: 1.03–1.12) and cRCTs (RR = 1.30, 95% CI: 1.07–1.59) and education-based (RR = 1.05, 95% CI: 1.02–1.09) and/or multifaceted interventions (RR = 1.11, 95% CI: 1.07–1.16) in ncRCTs. The interventions were effective in lowering LDL cholesterol but were not as effective in lowering total cholesterol. Conclusion: The study found heterogeneous evidence with limited certainty suggesting a potential modest improvement in statin adherence with interventions, where the effect sizes were small.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
