To address this gap, the present study developed and evaluated the feasibility and preliminary effectiveness of a structured intervention termed the \u201cFive-Discipline, Four-Phase, Three-Support\u201d closed-loop weight management model (5\u20134-3 Model). In this single-arm pre-post study conducted among psychiatric inpatients at Taizhou Second People\u2019s Hospital. We evaluated the model across multiple domains, including weight reduction and maintenance, patient-centered health outcomes, and healthcare team competency.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      A single-arm pre-post study was conducted from November 2024 to April 2025. Psychiatric inpatients with a body mass index (BMI)\u202f\u2265\u202f24\u202fkg\/m\n                      <jats:sup>2<\/jats:sup>\n                      were enrolled. The core intervention was the implementation of the 5\u20134-3 Model, a multidisciplinary closed-loop management system led by teams from psychiatry, nursing, clinical nutrition, rehabilitation medicine, and clinical pharmacy. The intervention comprised inpatient care (with a length of stay ranging from 1 to 6\u202fmonths) and a 3-month post-discharge follow-up. Weight at 3-month follow-up was primarily obtained via patient self-report, introducing potential reporting bias. Outcome measures included changes in body weight, BMI, and metabolic indices (extracted from hospital records), patients\u2019 weight management knowledge (assessed via a self-administered questionnaire), and staff awareness of weight management protocols and completeness of weight-related data recording. Data were analyzed using paired-sample t-tests.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      All 139 enrolled patients completed the 3-month follow-up assessment. Significant reductions were observed in body weight (mean change from admission to 3-month follow-up: \u22122.95\u202fkg; 95% CI -3.51 to \u22122.38;\n                      <jats:italic>p<\/jats:italic>\n                      \u202f&amp;lt;\u202f0.001) and BMI (mean change: \u22121.10\u202fkg\/m\n                      <jats:sup>2<\/jats:sup>\n                      ; 95% CI -1.28 to \u22120.92;\n                      <jats:italic>p<\/jats:italic>\n                      &amp;lt;\u202f0.001). Patients weight management knowledge scores increased from 27.82 to 53.45% (\n                      <jats:italic>p<\/jats:italic>\n                      &amp;lt;\u202f0.001).

However, causal attribution is limited by the uncontrolled single-arm design, and these findings should be considered preliminary.
