Objective To conduct a systematic review of randomised trials of patient decision aids in improving decision making and outcomes.
Design We included randomised trials of interventions providing structured, detailed, and specific information on treatment or screening options and outcomes to aid decision making.
Two reviewers independently screened and extracted data on several evaluation criteria.
Results were pooled by using weighted mean differences and relative risks.
Results 17 studies met the inclusion criteria.
Compared with the controls, decision aids produced higher knowledge scores (weighted mean difference=19/100,95% confidence interval 14 to 25) ; lower decisional conflict scores (weighted mean difference=-0.3/5, - 0.4 to - 0.1) ; more active patient participation in decision making (relative risk=2.27,95% confidence interval 1.3 to 4) ; and no differences in anxiety, satisfaction with decisions (weighted mean difference=0.6/100, - 3 to 4), or satisfaction with the decision making process (2/100, - 3 to 7).
Decision aids had a variable effect on decisions.
When complex decision aids were compared with simpler versions, they were better at reducing decisional conflict, improved knowledge marginally, but did not affect satisfaction.
Conclusions Decision aids improve knowledge, reduce decisional conflict, and stimulate patients to be more active in decision making without increasing their anxiety. (...)
