Breadth and exclusivity of hospital and physician networks in US insurance markets.
The goal of this study was to quantify network breadth and overlap among primary care physician (PCP), cardiology, and general acute care hospital networks for employer-based (large group and small group), individually purchased (marketplace), Medicare Advantage (MA), and Medicaid managed care (MMC) plans. The main outcomes measured were percentage of in-network physicians and/or hospitals within a 60-minute drive from a hypothetical patient in a given zip code (breadth), and the number of physicians and/or hospitals within each network that overlapped with other insurers' networks, expressed as a percentage of the total possible number of shared connections (exclusivity). Networks were categorized by network breadth size and analyzed by insurance type, state, and insurance, physician, and/or hospital market concentration level, as measured by the Hirschman-Herfindahl index. Markets with concentrated primary care and insurance markets had the broadest and least exclusive primary care networks among large-group commercial plans. Markets with the least concentration had the narrowest and most exclusive networks. Rising levels of insurer and market concentration were associated with broader and less exclusive healthcare networks. The authors suggest that this means that patients could switch to a lower-cost, narrow network plan without losing-in-network coverage to their PCP.

AHRQ series on improving translation of evidence: progress and promise in supporting learning health systems.
The authors discuss the articles in the AHRQ EPC series published in this journal over the past six months. They state that satisfaction, care, and costs would all improve if health care delivery were as efficient and effective as possible given current knowledge. They conclude that millions of health decisions must be made by clinicians, patients, and health care systems, and they believe better decisions will be made with evidence.
