Leveraging Diverse Data Sources to Identify and Describe U.S. Health Care Delivery Systems

Leveraging Diverse Data Sources to Identify and Describe U.S. Health Care Delivery Systems

Combining Data From Various Sources Provides Model for Examining U.S. Health Systems

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.

Abstract

Health care delivery systems are a growing presence in the U.S., yet research is hindered by the lack of universally agreed-upon criteria to denote formal systems. A clearer understanding of how to leverage real-world data sources to empirically identify systems is a necessary first step to such policy-relevant research. We draw from our experience in the Agency for Healthcare Research and Quality’s Comparative Health System Performance (CHSP) initiative to assess available data sources to identify and describe systems, including system members (for example, hospitals and physicians) and relationships among the members (for example, hospital ownership of physician groups). We highlight five national data sources that either explicitly track system membership or detail system relationships: (1) American Hospital Association annual survey of hospitals; (2) Healthcare Relational Services Databases; (3) SK&A Healthcare Databases; (4) Provider Enrollment, Chain, and Ownership System; and (5) Internal Revenue Service 990 forms. Each data source has strengths and limitations for identifying and describing systems due to their varied content, linkages across data sources, and data collection methods. In addition, although no single national data source provides a complete picture of U.S. systems and their members, the CHSP initiative will create an early model of how such data can be combined to compensate for their individual limitations. Identifying systems in a way that can be repeated over time and linked to a host of other data sources will support analysis of how different types of organizations deliver health care and, ultimately, comparison of their performance.
