Summary

The National Study of Physician Organizations was designed to improve understanding of evidence-based care management processes (CMPs) as they relate to physician organizations (POs), that is, independent practice associations (IPAs) and medical groups. This survey, the third NSPO survey of IPAs and medical groups (NSPO2), examined over 2000 physician organizations of all sizes. As in prior surveys, NSPO3 collected demographic information about the following practices and assesses: (1) use of clinical information technology; (2) use of care management processes to improve the quality of care for four chronic conditions (asthma, congestive heart failure, depression, and diabetes); (3) provision of clinical preventive services and health promotion; (4) exposure to external performance incentives such as pay for performance and public reporting; (5) payer mix, forms of compensation from health plans, and forms of compensation paid by the practice to its physicians; (6) organizational culture. In addition, NSPO3 asked about participation or intended participation in Accountable Care Organizations (ACOs).

Study Purpose

To provide healthcare organizations and researchers with important data on the management of four major chronic illnesses: asthma, coronary heart disease, depression, and diabetes.

Study Design

NSPO3 is a cross-sectional national survey of U.S. medical groups of all sizes.

Sample

The practices were sampled from the IMS Healthcare Organization Services database as of May, 2011. Organizations with a significant proportion of primary care providers (family physicians, general internists, and general practitioners), cardiologists, endocrinologists and/or pulmonologists were eligible for this study. Practices with 20 or fewer physicians were eligible if at least 40% were in the focal specialties, and practices with more than 20 physicians were eligible if at least 30% were in the focal specialties. Academic faculty practices and practices associated with federal hospitals were excluded.

Weight

Two types of weights are provided, sampling ("FWT") and longitudinal ("LWT") weights. The sampling weights should be applied for cross-sectional NSPO3 analysis. Longitudinal weights should be applied if conducting over-time analysis with NSPO2 and/or NSMPP respondents.
