Since Sept. 11, 2001, communities have responded to the federal call to enhance health care surge capacity—the space, supplies, staffing and management structure to care for many injured or ill people during a terrorist attack, natural disaster or infectious disease pandemic. Communities with varied experience handling emergencies are building broad surge capacity, including transportation, communication, hospital care and handling mass fatalities, according to a new study by the Center for Studying Health System Change (HSC).

Objective. Examine Medicare's local contractors' claim payment rules, focusing on how technology affects the balancing of competing demands to respond to local medical markets (rule heterogeneity) with concerns about national consistency in payment rules (rule homogeneity).

Data Sources. Local medical review policies (LMRPs) posted in policy sets by contractor organizations on the Centers for Medicare and Medicaid Services (CMS) website and a survey of Contractor Medical Directors.

The researchers assessed impacts of the Medicare Prospective Payment System (PPS) during its first two years of operation (1984-85) on 467 hospitals using data from the Commission on Professional and Hospital Activities and from the American Hospital Association. Medicare discharges as a per cent of total discharges remained constant between 1983 and 1985, but the per cent of uninsured patients increased, especially at large public hospitals. The number of Medicare and total discharges per hospital declined.

This study applies meta-analytic methods to conduct a quantitative review of the empirical literature on hospital ownership since 1990. We examine four financial outcomes across 40 studies: cost, revenue, profit margin, and efficiency. We find that variation in the magnitudes of ownership effects can be explained by a study's research focus and methodology. Studies using empirical methods that control for few confounding factors tend to find larger differences between for-profit and not-for-profit hospitals than studies that control for a wider range of confounding factors.

Many large U.S. companies have transformed their procurement of health benefits in the 1990s by combining the principles of managed competition with other business tactics to create a business-savvy hybrid of the private sector's own design, often referred to as "value purchasing." Until recently, few policymakers or health care observers believed that large firms would be a force in health system reform.

OBJECTIVE: To test the hypothesis that variation in reported access to health care is positively related to the level of social capital present in a community. DATA SOURCES: The 1996 Household Survey of the Community Tracking Study, drawn from 22 metropolitan statistical areas across the United States (n = 19,672).

The Medicare Modernization Act of 2003 created several new types of private insurance plans within Medicare, starting in 2006. Some of these plan types previously did not exist in the commercial market and there was great uncertainty about their prospects. In this paper, we show that statistical models and historical data from the Medicare Current Beneficiary Survey can be used to predict the experience of new plan types with reasonable accuracy. This lays the foundation for the analysis of program modifications currently under consideration.

This paper estimates a model of commercial HMO premiums based on Nash's axiomatic approach to bargaining between HMOs and employers. The bargaining models incorporate variables that measure the 'power' of the parties to affect the division of potential gains from a contract. It is found that an increase in the number of competing HMOs increases the employer's bargaining power and leads to lower premiums, especially for for-profit HMOs.
