To systematically analyze the intervention effect of continuing care on the health status of patients with metabolic and bariatric surgery (MBS), in order to provide a reference basis for clinical nursing staff to formulate relevant interventions.

In accordance with the PRISMA-ScR reporting guidelines, a comprehensive and systematic search was conducted in Embase, CINAHL Plus, PubMed, Web of Science, Cochrane Library, CNKI, Wanfang, VIP and CBM databases. The retrieval time was from inception of the database to May 1, 2025. Relevant studies were screened, summarized, analyzed, and reported according to the inclusion and exclusion criteria.

A total of 19 studies were included. The process of continuing care intervention could be summarized into six steps, including the establishment of a continuing care management team, establishment of health records and formulation of nursing plans, establishment of a communication platform for weight loss among doctors, nurses and patients in continuous nursing, standardization and visualization of health education, psychological care and regular follow-up visits. The outcome indicators mainly involved weight loss effects (BMI, body weight, waist circumference, hip circumference, blood pressure), quality of life, changes in blood glucose, psychological status (anxiety, depression), nursing satisfaction, dietary behavior control and compliance.

The content and form of continuing care intervention for MBS patients are diverse. It plays a positive role in maintaining the weight loss effect of MBS patients, improving the physical and mental health, and enhancing the quality of life. However, there is significant heterogeneity in the outcome indicators and their measure tools, and the follow-up time has not been clearly unified. In the future, the standardized process suitable for MBS patients should be explored and further verified, so as to provide evidence-based basis for clinical practice applications.
