Effectiveness of patient decision aids in patients with advanced kidney disease: a meta-analysis based on randomized controlled trials

Purpose To systematically evaluate the decision effectiveness of patient decision aids (PtDAs) on the decision-making effect of patients with advanced chronic kidney disease. Method Two authors independently searched ten electronic databases [Web of science, PubMed, the Cochrane Library, Embase, CINAHL, EBSCO, CBM, CNKI, WanFang DATA and Vip database], to include randomized controlled trials of interventions through PtDAs in patients with advanced chronic kidney disease published from the inception of the database until April 2024. Two authors conducted a comprehensive quality evaluation (Cochrane 5.1.0) before independently extracting and analyzing the data with RevMan 5.2. Results The study included 11 randomized controlled trials with a total of 1613 patients. According to the results, PtDAs can improve the decision knowledge [ SMD = 0.53, 95% CI (0.26, 0.80), P = 0.0002] and decision preparation [ SMD = 2.34, 95% CI (2.04, 2.65), P
