1. Tracking Disease Outbreaks: Hospitalization data can help identify and monitor the spread of infectious diseases, such as influenza or COVID-19, by analyzing trends in hospital admissions. 2. Evaluating Healthcare Interventions: By comparing hospitalization rates before and after the implementation of a healthcare intervention, researchers can assess its effectiveness. 3. Health Services Research: Researchers use hospitalization data to study healthcare utilization patterns, identify gaps in services, and optimize healthcare delivery. 4. Chronic Disease Management: Hospitalization data is crucial for understanding the impact of chronic diseases like diabetes and heart disease on the healthcare system and for improving management strategies.
