Abstract: Objective: To evaluate the effects of the Shared Decision Making intervention on outcomes of patients with diabetes. Methods: Databases including PubMed, Embase, the Cochrane Library, Web of Science, CNKI, WanFang Data, VIP Data and CBM were comprehensively searched for randomized controlled trials on the effects of the Shared Decision Making intervention on outcomes of patients with diabetes from July 2, 2011 to July 2, 2021. There were 2 researchers independently screened the articles, evaluated the quality and extracted data of the included studies. The Meta-analysis was performed with RevMan 5. 3 software. Results: A total of 14 articles and 2325 diabetes patients were included. The Shared Decision Making intervention could alleviate the decisional conflict of patients with diabetes (P=0.0007), improve their decision self-efficacy (P=0.0002), improve their medication compliance (P=0.03) and reduce their BMI (P=0.01). The intervention could reduce HbA1c level in 3 months (P=0.001), however, it did not change the HbA1c level of patients in 6 months (P=0.23) or 24 months (P=0.27). Conclusion: The Shared Decision Making intervention can improve decision-making quality in patients with diabetes, improve their medication compliance, and reduce their HbA1c values in 3 months. It is suggested that more studies can be conducted to further investigate the effects of the Shared Decision Making intervention on outcomes of patients with diabetes in the future.
