Geospatial, Clinical, and Social Determinants of Hospital Readmissions

Area of Science:

• Healthcare Management
• Clinical Epidemiology
• Health Services Research

Background:

• Unnecessary hospital readmissions negatively impact patient well-being, healthcare quality, efficiency, and costs.
• Identifying patients at high risk for readmission is essential for targeted intervention strategies.

Purpose of the Study:

• To identify patient characteristics associated with a higher risk of 90-day hospital readmission.
• To inform the development of interventions aimed at reducing hospital readmissions.

Main Methods:

• Retrospective cohort study analyzing electronic health records of 42,330 adult patients.
• Comparison of geospatial, social demographic, and clinical characteristics between readmitted and non-readmitted patients.
• Logistic regression analysis to determine significant risk factors for readmission.

Main Results:

• The overall 90-day readmission rate was 14.9%.
• Patients with severe conditions, especially those with a short length of stay during their initial admission, showed significantly higher odds of readmission.
• Patients with Medicare coverage who were younger than 65 years also presented significantly higher odds of a 90-day readmission.

Conclusions:

• Severe conditions and specific demographic factors (younger Medicare beneficiaries) are significant predictors of hospital readmissions.
• Findings highlight specific high-risk patient groups for future readmission reduction interventions.
• Targeted interventions focusing on these identified groups could improve healthcare efficiency and reduce patient burden.
