Regional supply of medical resources and systemic overuse of health care among Medicare beneficiaries.
The goal of this study was to explore health care system factors associated with regional variation in overuse of resources, as measured by the Johns Hopkins Overuse Index (JHOI). Medicare fee-for-service claims data from beneficiaries age 65 was used to calculate the JHOI for 306 hospital referral regions in the U.S. Regions with a higher density of primary care physicians had a lower JHOI, which indicates less systemic overuse. Regional characteristics associated with higher JHOI included the number of acute care hospital beds per 1000 residents and number of hospital-based anesthesiologists, pathologists, and radiologists. The authors conclude that regional variations in health care resources are associated with the level of systemic overuse of health care, and that the role of primary care doctors in reducing overuse deserves further attention.

Effects of a 1-time nurse-led telephone call after pediatric discharge: the H2O II randomized clinical trial.
The purpose of this study was to determine whether a single nurse-led telephone call after pediatric discharge decreased the 30-day reutilization rate for urgent care services and enhanced overall transition success. The investigators concluded that although postdischarge nurse contact did not decrease the reutilization rate of postdischarge urgent health care services, the method showed promise to bolster postdischarge education.

Trends in health care utilization for asthma exacerbations among diverse populations with asthma in the United States.
This article discusses trends in asthma hospitalization and outpatient visit rates from 2004 to 2010. The rates for all populations included in this study went down during the time period, in particular the population from the Tennessee Medicaid program (49%). Other populations used in the study included subjects 4 to 50 years enrolled in the US Department of Defense Military Health System (MHS), and 3 large integrated health delivery systems (IHCDS) of the Population Based Effectiveness in Asthma and Lung Diseases (PEAL) Network. The 3 PEAL health plans included Harvard Pilgrim Health Care, Kaiser Permanente Georgia, and Kaiser Permanent Northern California. A total of 473,524 subjects in those 3 study populations were identified. These downward trends are encouraging but need to continue, particularly in diverse populations.
