Healthcare Providers are having to make quicker, riskier decisions in a competitive and regulated environment. Leaders often make these decisions with the advice of management consultants; however, top management generally lacks adequate internal support to rigorously evaluate strategic interventions or consultant recommendations and to learn from industry-wide best practices. In fact, healthcare providers generally underinvest in management support, both in evaluating best practices within the organization and in learning from past strategic interventions. The creation of evidence-based management cooperatives might be a means to change this trend.

The financing of asthma care is the third topic of the National Asthma Education and Prevention Program Task Force Report on the Cost Effectiveness, Quality of Care, and Financing of Asthma Care. This working group explored the effects of financing on access to services, treatment of asthma, and potential health outcomes. Over the course of a year, the working group collected and analyzed information pertaining to the various types of public and private health care financing mechanisms, including both insurance-based and non-insurance-based issues. The group examined the published literature and gathered information from four public hearings conducted across the nation. The result of this synthesis of information on health care financing and asthma care is a set of 12 recommendations that seek to improve the financing of asthma care.

Disparities in health outcomes for low-income populations as documented by rates of preventable hospital admission remains large in the United States, even with the moderate expansion of Medicaid and efforts at the state and local levels to improve primary care services that began in the mid-1980s. These differences in outcome for rich and poor are not an isolated phenomenon of a few old and decaying Northeast urban centers but are documented in a broad range of urban areas. Much smaller differences are found in urban areas in Ontario, where universal coverage may help to reduce barriers to care.

OBJECTIVE: To examine whether the higher hospital admission rates for chronic medical conditions such as asthma, hypertension, congestive heart failure, chronic obstructive pulmonary disease, and diabetes in low-income communities resulted from community differences in access to care, prevalence of the diseases, propensity to seek care, or physician admitting style. DESIGN: Analysis of California hospital discharge data. We calculated the hospitalization rates for these five chronic conditions for the 250 ZIP code clusters that define urban California. We performed a random-digit telephone survey among adults residing in a random sample of 41 of these urban ZIP code clusters stratified by admission rates and a mailed survey of generalist and emergency physicians who practiced in the same 41 areas. SETTING: Community based. PARTICIPANTS: A total of 6674 English- and Spanish-speaking adults aged 18 through 64 years residing in the 41 areas were asked about their access to care, their chronic medical conditions, and their propensity to seek health care. Physician admitting style was measured with written clinical vignettes among 723 generalist and emergency physicians practicing in the same communities. MAIN OUTCOME MEASURES: We compared respondents' reports of access to medical care in an area with the area's cumulative admission rate for these five chronic conditions. We then tested whether access to medical care remained independently associated with preventable hospitalization rates after controlling for the prevalence of the conditions, health care seeking, and physician practice style. RESULTS: Access to care was inversely associated with the hospitalization rates for the five chronic medical conditions (R2 = 0.50; P < .001). In a multivariate analysis that included a measure of access, the prevalence of conditions, health care seeking, and physician practice style to predict cumulative hospitalization rates for chronic medical conditions, both self-rated access to care (P < .002) and the prevalence of the conditions (P < .03) remained independent predictors. CONCLUSION: Communities where people perceive poor access to medical care have higher rates of hospitalization for chronic diseases. Improving access to care is more likely than changing patients' propensity to seek health care or eliminating variation in physician practice style to reduce hospitalization rates for chronic conditions.

This DataWatch examines the potential impact of socioeconomic differences on rates of hospitalization, based on patterns of hospital use in New York City in 1988. The research suggests that lack of timely and effective outpatient care may lead to higher hospitalization rates in low-income areas. For certain conditions identified as ambulatory care sensitive, hospitalization rates were higher in low-income areas than they were in higher-income areas where appropriate outpatient care was more readily available. Further study is needed to determine the relative impact of various economic, structural, and cultural factors that affect access to care.
