Background: Approximately 80% of multihospital system member hospitals in U.S. urban areas are clustered with other same-system member hospitals located in the same market area.

Since the 1990s, rapid consolidation in the hospital sector has resulted in the vast majority of hospitals joining systems that already had a considerable presence within their markets. We refer to these important local and regional systems as "clusters." To determine whether hospital clusters have taken measurable steps aimed at improving the quality of care-specifically, by concentrating low-volume, high-complexity services within selected "lead" facilities-this study examined within-cluster concentrations of high-risk cases for seven surgical procedures.

This represents periods before and after the VHA in 1995 reconfigured provider units into 21 regionalized delivery systems and engaged in other important system innovations. Productivity is measured using the Malmquist Index approach (a longitudinal version of the data envelopment analysis [DEA]).

Background: The literature points to possible efficiencies in local-hospital-system performance, but little is known about the internal dynamics that might contribute to this. Study of the service arrangements that nearby same-system hospitals have with one another should provide clues into how system efficiencies might be attained.
Purposes: The purpose of this research was to better understand the financial and operational effects of service sharing and receiving arrangements among nearby hospitals belonging to the same systems.

Background: The rapid increase in the number of hospitals becoming members of multihospital systems in recent decades has led to the formation of local and regional clusters that have the potential to function as regional systems, a model long advocated as a policy strategy for improving health system performance.
Purpose: This study addresses both cluster efficiency and the hierarchical configuration with which hospitals are grouped into clusters.
Methodology/approach: This study uses 2004 data from the American Hospital Association Annual Survey multihospital system designations updated to 2005.
Background: Hospital administrators face challenging decisions about whether to maintain, cut, or add services in response to changes in consumer demand or managed-care pressures. The challenge is heightened for services that are also offered by other hospitals in the local community.
Purposes: This study provides evidence on the financial effects of providing services that are also provided by other hospitals in the same county.
Objective: To assess a widely recognized multihospital system taxonomy.
Data Sources: The original taxonomy was based on American Hospital Association (AHA) Annual Survey Data for the years 1994 and 1995 and a reexamined version, on 1998 AHA data.
Study Design: We assess the appropriateness of using data designed to capture local hospital/system interrelationships to develop a taxonomy of multihospital systems.
In past years, many SHAs formed in local urban markets to better compete for managed care contracts. In response to 1990s forces, these SHAs appear to have adapted product, production, and selling orientations to their markets, aimed at large institutional purchasers of health care. However, health care markets have evolved differently than anticipated.
