Leveraging Diverse Data Sources to Identify and Describe U.S. Health Care Delivery Systems
- No single national data source provides a complete picture of US health care delivery systems and their component hospitals, physician practices and physicians.
- Combining various sources can help compensate for each source’s limitations, and when information overlaps across sources, it can be used for validation
- Being able to examine linkages among system components gives researchers flexibility to tailor the definition of systems according to the objectives of their analysis
- The CHSP initiative recently released an inaugural Compendium of US Health Care Systems, which provides an early model of how such data can be used to identify systems in a way that can be updated or repeated over time and linked to other data sources to support analysis of how different types of organizations delivery health care.
