Purpose:
A shared decision-making (SDM) process centered on the patient perspective may increase understanding and treatment satisfaction. This study aimed to investigate whether SDM would increase the acceptance of bariatric/metabolic surgeries, change treatment decisions, and affect 1-year results.
Materials And Methods:
This retrospective analysis enrolled 315 consecutive patients with a body mass index between 32.5 and 50 kg/m2 and aged 20-65 years who underwent consultation for a primary bariatric/metabolic procedure within 2 years before (pre-SDM) or after (post-SDM) SDM program implementation to assist in the decision to undergo Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG) surgery. Consent rate, procedure choice, weight loss, comorbidity remission, etc., were compared between periods and procedures. Statistical tests were two-sided, with p < 0.05 considered significant.
Results:
More eligible patients underwent metabolic/bariatric procedures post-SDM than pre-SDM (115/159 [72%] vs. 106/156 [68%]; p = 0.395), and a stronger preference for RYGB post-SDM was observed (71% vs. 62%; p = 0.153). Significantly more patients with diabetes (28 [34.1%] vs. 5 [15.2%]; p = 0.041) chose RYGB over SG post-SDM. Patients who underwent RYGB had a higher diabetes remission rate both pre-SDM (70.0% vs. 58.3%; p = 0.571) and post-SDM (76.2% vs. 66.7%; p = 0.712) than those who underwent SG. While 1-year weight loss was similar between procedures, adherence to nutritional supplementation did not appear to be broadly enhanced post-SDM.
Conclusion:
SDM influenced procedure selection toward RYGB, which was more popular than SG among patients with diabetes. Higher diabetes remission was achieved with RYGB, although the results of other effects deserve further study.
