No single national data source provides a complete picture of U.S. health systems, but AHRQ’s Comparative Health System Performance (CHSP) initiative provides an early model of how data from different sources can be combined to support policy research, a new study found. The CHSP initiative was developed to explore how health care delivery systems promote evidence-based practices and patient-centered outcomes research in delivering care. The new study, published in eGEMS, analyzed five national data sources that describe systems’ members (e.g., hospitals, physicians) and relationships among them (e.g., hospital ownership of physician groups). Researchers concluded that CHSP provides a model for combining data from different sources despite variations in content, linkages across data sources and collection methods. Access the abstract.
