Abstract

BACKGROUND AND PURPOSE: This systematic review examines the effectiveness of motivational interviewing (MI) on medication adherence for preventing recurrent stroke and transient ischemic attack (TIA).

METHODS: MEDLINE (via PubMed), CINAHL, PsycINFO, CENTRAL, and ClinicalTrials.gov were searched from inception to 12 June 2023. Randomized controlled trials comparing MI with usual care or interventions without MI in participants with any stroke type were identified and summarized descriptively. Primary outcome was medication adherence. Secondary outcomes were quality of life (QoL) and different clinical outcomes. We assessed risk of bias with RoB 2 (revised Cochrane risk-of-bias tool) and intervention complexity with the iCAT_SR (intervention Complexity Assessment Tool for Systematic Reviews).

RESULTS: We screened 691 records for eligibility and included four studies published in five articles. The studies included a total of 2751 participants, and three were multicentric. Three studies had a high risk of bias, and interventions varied in complexity. Two studies found significantly improved medication adherence, one at 9 (96.9% vs. 88.2%, risk ratio = 1.098, 95% confidence interval = 1.03-1.17) and one at 12 months (97.0% vs. 95.0%, p = 0.026), but not at other time points, whereas two other studies reported no significant changes. No significant differences were found in QoL or clinical outcomes.

CONCLUSIONS: Evidence on MI appears inconclusive for improving medication adherence for recurrent stroke and TIA prevention, with no benefits on QoL and clinical outcomes. There is a need for robustly designed studies and process evaluations of MI as a complex intervention for people with stroke.
