Toward an empirical classification of hospitals in multihospital systems.
Inconsistency and lack of utility in multihospital systems research is often attributable to misspecification of the unit of analysis and lack of generalizability of research findings. The typical, system-level focus takes an "organizations are all alike" approach that masks potentially important variation among constituent hospitals in systems. This article develops and validates a multivariate, empirical typology of hospitals affiliated with multihospital systems. The objective of the typology is to identify prevalent types of system hospitals that share similar organizational and operational characteristics. Three hundred and sixty-six hospitals affiliated with secular, not-for-profit multihospital systems were subjected to cluster analysis within and across affiliation categories (owned, leased, and contract managed). Findings indicate that the population of hospitals in not-for-profit systems is organizationally heterogeneous but that distinct groupings of hospitals, based largely on size and affiliation status, occur within this population. Homogeneous groupings of hospitals were tested for differences in governance and performance characteristics. Although these clusters differ only slightly in their governance characteristics, they do manifest several differences in performance characteristics. Implications and applications of these findings are discussed.
