Area of Science:

• Medical Science
• Transitional Care Research
• Patient Outcomes

Background:

• Patients undergoing biliary drainage face a high risk of hospital readmission.
• Transitional care programs aim to improve post-discharge outcomes for high-risk patient populations.

Purpose of the Study:

• To evaluate a Chronic Care Model (CCM)-based transitional care program for patients requiring biliary drainage.
• To assess the program's impact on 90-day readmission and complication rates.
• To identify predictors of readmission using patient-reported metrics and machine learning models.

Main Methods:

• A prospective, two-center randomized controlled trial involving 300 patients undergoing biliary drainage.
• Comparison between an intervention group (CCM-based transitional care) and a control group (usual care).
• Analysis of primary outcomes (90-day readmission, complications) and secondary outcomes (discharge readiness, self-care, quality of life).
• Development of predictive models using logistic regression and Support Vector Machine (SVM).

Main Results:

• The intervention group showed significantly lower 90-day readmission rates (16.3% vs. 37.1%) and complication rates (12.1% vs. 26.5%).
• Intervention patients reported significantly higher scores for discharge readiness, self-care behavior, and quality of life.
• Patient-reported scores predicted lower readmission risk, and the SVM model demonstrated high accuracy in predicting readmission risk (AUC: 0.93).

Conclusions:

• A structured CCM-based transitional care program is effective in reducing readmissions and complications for patients with biliary drainage.
• The program promotes prolonged community-based stability.
• Patient-reported metrics, when integrated into an SVM model, can accurately predict readmission risk, enabling targeted interventions.
