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 < 0.00001] of patients with advanced chronic kidney disease. Additionally, there was a substantial decrease in the levels of decision regret [SMD = - 1.33, 95% CI (- 2.11, - 0.55), P < 0.05] and decision conflict [SMD = - 0.88, 95% CI (- 1.47, - 0.28), P = 0.004].

Conclusion: The current available evidence indicates that PtDAs can significantly enhance the decision knowledge and decision preparation of patients with advanced chronic kidney disease. Additionally, PtDAs can reduce the levels of decision regret and decision conflict.
