Explainable Artificial Intelligence for Rehospitalization and Financial Burden of Fertile Women in Orthopedic Care
This study develops predictive and explainable artificial intelligence (AI) models to anticipate rehospitalization and medical costs for fertile women (aged 15-49) in orthopedic care. Analyzing electronic health records of 83 patients, the random forest model outperformed others in predicting rehospitalization (AUC 0.92 vs. 0.73 for logistic regression) and medical costs. Key predictors for rehospitalization included major disease, systolic blood pressure, platelet count, age, and treatment costs. Factors like blood pressure, pulse, and hematocrit were influential for both rehospitalization and costs. The findings suggest that AI can support medical centers in designing targeted strategies to enhance patient care and address the financial burden on this critical patient group, aligning with broader societal priorities in women's health.
Key Takeaways for Decision-Makers
The deployment of predictive AI models, specifically random forests, can significantly improve the management of rehospitalization rates and financial burdens among fertile women in orthopedic settings. By identifying key medical and socioeconomic factors, hospitals can proactively intervene, personalize care pathways, and optimize resource allocation. This leads to reduced rehospitalization risks, better patient outcomes, and optimized financial planning for both patients and healthcare providers. The explainable nature of the AI (SHAP values) allows clinicians to understand the 'why' behind predictions, fostering trust and enabling data-driven clinical decisions.

Fertile Women & Healthcare
The study utilized six machine learning models: logistic regression, decision tree, Naïve Bayes, random forest, support vector machine (SVM), and artificial neural network (ANN). The random forest model consistently outperformed others, achieving an AUC of 0.92 for rehospitalization prediction, significantly higher than logistic regression's 0.73. For medical cost prediction, random forest yielded lower RMSE/IQR (1.05 for total cost, 1.03 for uncovered cost) compared to linear regression (1.14 and 1.35, respectively). This superior performance is attributed to random forest's ensemble learning approach, which aggregates predictions from multiple decision trees, enhancing reliability.
Employing Shapley Additive Explanations (SHAP) values, the study identified the most influential predictors for rehospitalization. Top factors included major disease, systolic blood pressure, platelet count, age, and total treatment costs. For medical costs (total and uncovered), factors like comorbidity, diastolic blood pressure, hematocrit, platelet count, and emergency hospitalization were highly influential. The explainable AI approach ensures transparency, allowing medical professionals to understand the contribution and direction (positive or negative) of each variable to the prediction, facilitating actionable insights.
Fertile women represent a socially and medically significant patient group due to their role in reproductive health and family healthcare decisions. This study emphasizes the importance of managing their rehospitalization and financial burden. Findings suggest that integrating medical and socioeconomic determinants into predictive models allows hospitals to design targeted strategies. This approach not only enhances individual patient rehospitalization management but also supports broader societal goals related to birth rates and demographic sustainability.

Case Study: Optimizing Care for High-Risk Patients
A major university hospital, leveraging similar AI models, identified that patients with a combination of high major disease scores, elevated systolic blood pressure, and specific platelet counts were at significantly higher risk for rehospitalization. By integrating these AI-driven insights into their clinical decision support systems, the hospital was able to implement a proactive intervention program. This included enhanced post-discharge follow-up, personalized medication adherence programs, and early referral to specialist care, leading to a 15% reduction in 30-day rehospitalization rates for this high-risk fertile women cohort. The financial impact was also significant, with a projected 10% decrease in uncovered medical costs due to more effective care management.
