Hospital cluster size impacts service duplication, with larger clusters offering more rationalization opportunities. For-profit hospital systems may lead in optimizing services across their networks.
Area of Science:
- Health Services Research
- Healthcare Management
- Hospital Administration
Background:
- Most U.S. urban multihospital systems cluster member hospitals within the same market area.
- Hospital clustering is often justified by the potential to reduce service duplication among member facilities.
Purpose of the Study:
- To investigate how hospital cluster characteristics influence service duplication.
- To analyze service duplication within 339 hospital clusters in U.S. metropolitan statistical areas and adjacent counties in 2002.
Main Methods:
- Employed ordinary least squares regression analysis.
- Examined the relationship between 1998 cluster characteristics and 2002 duplicated services per member.
Main Results:
- Higher case mix index and broader bed size range correlated with increased service duplication.
- Greater number of members, for-profit ownership, and increased geographic dispersion were associated with lower service duplication.
Conclusions:
- Larger hospital clusters present greater potential for service rationalization.
- For-profit hospital clusters may be early adopters of rationalization strategies and warrant further study.
- Clusters with high case mix, limited geographic spread, and hub-and-spoke designs may face challenges in service reallocation.

Rural health centers are specialized care facilities in remote locations with very few medical personnel. The primary care providers who run the centers are mostly Registered Nurse Practitioners. Here, emergency treatment is provided to critically ill or injured patients before they are transferred to the closest hospital. Fortunately, due to advancement in technology, many rural healthcare facilities and professionals have easy access to diagnostic and treatment...
