Abstract
OBJECTIVE: Oral anticoagulant (OAC) prescription for stroke prevention in atrial fibrillation (AF) patients frequently does not follow current guidelines, with underuse in patients at high risk of stroke and substantial overuse in those at low risk. This review aims to systematically evaluate the effectiveness of interventions to improve appropriate OAC prescription in eligible AF patients for stroke prevention. METHODS: Systematic review of controlled and uncontrolled studies published up to July 2017 with interventions designed to improve appropriate OAC prescription for stroke prevention in eligible AF patients (according to risk assessment tool or guidelines). Categorization of intervention types was pre-specified. The main outcome was change in proportion of eligible AF patients prescribed OACs for stroke prevention. RESULTS: Twenty studies conducted in 392 settings were included (cluster randomized controlled trials, controlled trials and uncontrolled before-after designs; n = 29,868 patients at baseline). Fifteen studies reported significant improvements in appropriate prescription of OACs in AF patients. All interventions with a persuasive element (8/8); all studies targeting health care professional (HCP) education or guideline/protocol implementation (7/7); and all medical care programs (4/4) achieved significant increases in appropriate OAC prescription. Computerized decision support interventions (3/5) and reviews of prescribing (2/4) were less likely to report significant improvements in appropriate OAC prescription. CONCLUSION: Interventions designed to improve appropriate prescription of OACs in eligible AF patients for stroke prevention can be effective. Successful approaches include education of HCPs; implementation of local guidelines; interdisciplinary medical care programs educating both HCPs and patients and persuasive interventions utilizing peer-group experts.
