Mental Health Hospital Readmission Risk Index from a Spanish Hospital Study

A 2026 study by Yaiza García-Illanes developed a 30-day readmission risk index using 196 admission episodes from the Mental Health Hospitalization Unit of the Hospital Regional Universitario de Málaga. The dataset likely contains patient variables used in a retrospective case–control design, resulting in a predictive model with an AUC of 0.764. The exploratory study is published under a CC-BY-4.0 license.

Use Cases

• Training a readmission risk classifier based on identified predictive variables like previous admissions and personality disorder.
• Benchmarking new predictive models against the reported optimism-corrected AUC of 0.727.
• Analyzing the relationship between social risk factors and hospital readmission outcomes.
• Developing post-discharge planning tools using risk scores derived from variables like emergency service use and aggressive behavior.

Strengths

• Model performance is quantitatively reported with an AUC of 0.764 and internal validation metrics.
• The study design is clearly described as a retrospective case–control study with 98 cases and 98 controls.
• Specific predictive variables, such as previous hospital admissions and marital status, are identified.

Limitations

• Row count and column-level documentation are unknown, limiting suitability assessment.
• The dataset is very small at 220.6 KB, indicating limited scope.
• The exploratory nature of the study, as noted in the description, suggests results should be used cautiously.
