Objective  To investigate the application effectiveness of discharge preparation services based on the information-motivation-behavior (IMB) model on patients undergoing metabolic and bariatric surgery (MBS).

Methods  Patients who underwent MBS in April 2022 at the Obesity and Metabolic Disease Surgery Center in Zhongnan Hospital of Wuhan University were selected as the control group, and patients who underwent MBS in September 2022 were selected as the observation group. The control group received the conventional perioperative management model for patients undergoing MBS, while the observation group received the discharge preparation services based on the IMB model. The discharge readiness and discharge guidance quality scores, the awareness rate of MBS postoperative knowledge and the effect of rapid rehabilitation of the two groups of patients were compared.

Results  A total of 98 patients were included, including 52 in the observation group and 46 in the control group. After the intervention, compared with the control group, the observation group demonstrated higher scores in discharge readiness and discharge guidance quality, improved awareness of postoperative knowledge, shorter hospital stays, earlier postoperative ambulation initiation, and faster return of bowel function, along with lower 1-month unplanned readmission rates, and the differences were statistically significant (P<0.05).

Conclusion  The use of discharge preparation service baseds on IMB model can significantly improve the awareness rate of patients’ weight loss professional knowledge after MBS, improve the patient’s discharge preparation and discharge guidance quality, accelerate the postoperative rehabilitation of patients, reduce the unplanned readmission rate of patients. The intervention model has certain application value in clinical practice.
