A Decision Aid to Help Patients Make Informed Choices Between the Laparoscopic Gastric Bypass or Sleeve Gastrectomy

In the Netherlands, patients can often choose between the laparoscopic Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) as primary bariatric surgery. Yet, patients confronted with medical options may experience decisional conflict when their stakes are high and outcomes uncertain. This study aimed to assess if a decision aid helps patients make informed choices between two bariatric procedures by lowering the level of decisional conflict.

This study was a single-center comparative cohort of patients who accessed a web-based decision aid (intervention group) and those who did not use the decision aid (control group) to help choose between two bariatric procedures additional to the standard provided care. The primary outcome was the level of decisional conflict in these patients using the decisional conflict scale (DCS). Secondary outcomes were patient satisfaction with the provided information (BODY-QTM-satisfaction with information), preference of involvement in procedure selection, level of shared decision-making (SDM-Q-9 questionnaire), and patient knowledge.

The level of decisional conflict assessed with the decisional conflict scale (DCS) showed a significantly lower mean total DCS of 25.5 ± 11.5 for the intervention group vs. 29.1 ± 12.4 in the control group (p = 0.022). Both groups did not significantly differ in satisfaction regarding provided information, involvement in the selection procedure, shared decision-making, and patient knowledge.

The results suggest that the additional use of a decision aid significantly lowers the level of decisional conflict in patients awaiting bariatric surgery. However, the added value should be further investigated.
