Appendix G
Health System Cluster Code Descriptions

Recent research using existing theory and AHA Annual Survey data identified a reliable set of five distinct groups of health systems that share common strategic/structural features.  This new identification system was developed jointly by the American Hospital Association’s Health Research and Educational Trust and Health Forum, and the University of California-Berkeley. For further information on the development of the taxonomy please see: Bazzoli, GJ; Shortell, SM; Dubbs, N; Chan,C; and Kralovec, P; “A Taxonomy of Health Networks and Systems: Bringing Order Out of Chaos” Health Services Research,  February; 1999.  A health system is assigned to one of five categories based on how much they differentiate and centralize their hospital services, physician arrangements, and provider-based insurance products. Differentiation refers to the number of different products or services that the organization offers. Centralization refers to whether decision-making and service delivery emanates from the system level more so than individual hospitals.  

Code	Label	Description	
1	Centralized Health System	A delivery system in which the system centrally organizes individual hospital service delivery, physician arrangements, and insurance product development.  The number of different products/services that are offered across the system is moderate.	
2	Centralized Physician/Insurance Health System	A delivery system with highly centralized physician arrangements and insurance product development.  Within this group, hospital services are relatively decentralized with individual hospitals having discretion over the array of services they offer.  The number of different products/services that are offered across the system is moderate.	
3	Moderately Centralized Health System	A delivery system that is distinguished by the presence of both centralized and decentralized activity for hospital services, physician arrangements, and insurance product development.  For example, a system within this group may have centralized care of expensive, high technology services, such as open heart surgery, but allows individual hospitals to provide an array of other health services based on local needs.  The number of different products/services that are offered across the system is moderate.	
4	Decentralized Health System	A delivery system with a high degree of decentralization of hospital services, physician arrangements, and insurance product development.   Within this group, systems may lack an overarching structure for coordination.  Service and product differentiation is high, which may explain why centralization is hard to achieve.  In this group, the system may simply serve a role in sharing information and providing administrative support to highly developed local delivery systems centered around hospitals.	
5	Independent Hospital System	A delivery system with limited differentiation; hospital services, physician arrangements, and insurance product development.  These systems are largely horizontal affiliations of autonomous hospitals.	
blank		Sufficient data from the 1998 Annual Survey were not available to determine a cluster assignment.

Additional Explanation of Codes and Fields

Estimation Codes
Code	Description	
0	The value was reported by the hospital	
1	The value was estimated since no value was reported by the hospitals	
2	The value has been expanded, since the reported value is associated with a reporting period of less than 1 full year	

•	If the hospital did not respond to the survey (RESP=2), the following fields were obtained from previously reported data.
AHA ID	Hospital Name	Bed Size code	
Control/Ownership	CEO Name	Length of Stay code	
Primary Service code	Address	CMSA code	
Number of Bassinets	City	MSA code	
Total Beds	State	County code	
Membership Type	ZIP code	City Rank	
Long term/Short term flag	Area code	MSA Size	
Control Code – Membership	Telephone number	All accreditation and affiliation flags 	
Service Code - Membership	Community Hospital Flag (CHC)	(MAPP1 through MAPP17)	

•	All fields with corresponding estimation fields have been estimated or expanded.  Other fields, such as facilities and services were left blank.
•	If the separate units code (SUNITS) is 2, all short-term and long-term data fields are blank.

Modified FIPS County Code
County codes generally are odd numbers assigned to an alphabetical listing of the counties within a state.  Baltimore City is included in Baltimore County, St Louis City is included in St Louis County, and the independent cities in Virginia are each included in the contiguous counties.  Kalawao County, Hawaii is included in Maui County.  The four Alaska Judicial Divisions were used as counties.

Long term/Short  term Flag (LOS)
If a separate long-term unit is reported and long-term admissions are greater than one-half of total admissions, then LOS is 2; otherwise LOS is 1.  If a separate long-term unit is not reported and the ratio of inpatient days to admissions is 30 or more, then LOS is 2; otherwise LOS is 1.
