WASHINGTON, DC—Two Center for Studying Health System Change (HSC) studies—one on the development of hospital-physician portals to share patient data electronically, and the other examining the role of community health centers in improving access to care for minorities—were published today in the November/December edition of Health Affairs.

Hospital-Physician Portals: The Role of Competition in Driving Clinical Data Exchange by Joy M. Grossman, Ph.D, HSC senior researcher; Thomas S. Bodenheimer, M.D., HSC senior consulting researcher; and Kelly McKenzie, HSC health research analyst

Recent policy efforts to encourage the use of health information technology are emphasizing development of community-wide health information exchanges to share clinical data across patient care settings. Based on findings from HSC’s 2005 site visits to 12 nationally representative communities, the study found that most large hospitals have or are developing physician portals to provide admitting physicians with remote access to patient records, but there is little data sharing among unaffiliated organizations. Competition among hospitals for physicians is a key factor driving adoption of these proprietary systems. In contrast, provider and health plan competition and adversarial relationships between providers and plans are viewed as major barriers to community-wide clinical data sharing.

The 12 nationally representative communities are Boston; Cleveland; Greenville, S.C.; Indianapolis; Lansing, Mich.; Little Rock, Ark.; Miami; northern New Jersey; Orange County, Calif.; Phoenix; Seattle; and Syracuse, N.Y. HSC has been tracking changes in these markets for the past 10 years.

Would Safety-Net Expansions Offset Reduced Access Resulting from Lost Insurance Coverage? Race/Ethnicity Differences by Jack Hadley, Ph.D., HSC senior fellow and principal research associate at the Urban Institute; Peter Cunningham, Ph.D, HSC senior fellow; and J. Lee Hargraves, research associate professor at the University of Massachusetts Medical School in Worcester

This study simulated whether increased community health center (CHC) funding under the Bush administration narrowed racial/ethnic gaps in access to care among low-income people. Expanded CHC funding resulted in small increases in access to care, more so for minorities than for whites. Spanish-speaking Hispanics had the largest improvements in access in the simulation. However, minorities experienced bigger drops in insurance coverage. The net result was no improvements in the access measures for Spanish-speaking Hispanics and slight decreases in access for whites, English-speaking Hispanics and African Americans. Access gaps either remained the same or worsened slightly for English-speaking Hispanics and African Americans relative to whites.

The Center for Studying Health System Change is a nonpartisan policy research organization committed to providing objective and timely research on the nation’s changing health system to help inform policy makers and contribute to better health care policy. HSC, based in Washington, D.C., is funded principally by The Robert Wood Johnson Foundation and is affiliated with Mathematica Policy Research, Inc.
