Toward an Empirical Classification of Hospitals in Multihospital Systems

A Taxonomy of Accountable Care Organizations for Policy and Practice

“…The primary analytic steps in taxonomical work have been identified in prior work (Alexander, Anderson, and Lewis ; Ketchen and Shook ; Bazzoli et al. ) and consist of the following three stages: Cluster analysis to formulate groupings based on several ACO characteristics that are similar among grouped observations; Pairwise comparisons to determine which characteristics are similar or dissimilar across clusters; Discriminant analysis to validate the cluster solutions, using discriminant functions to determine rates of correct classifications. …”

Organizational Ecology and Health Services Research: New Answers for Old and New Questions

“…The areas of taxonomies and classification systems have experienced significant recent interest in health services organization research as new corporate forms and multiunit systems have emerged in the past decade (Fottler et al 1982;Alexander, Anderson, and Lewis 1985;Lewis and Alexander 1986). These forms represent serious managerial and analytical challenges to a field which had seen considerable form stability and had shown little interest in classification of enterprises beyond principal services, ownership, size, and, more recently, case-mix complexity.…”

“…While some significant exploratory empirical work has been done (Fennell 1980;Rundall and McClain 1982;Alexander, Anderson, and Lewis 1985; Lewis and Alexander 1986), these studies cannot be construed as representing comprehensive efforts to adopt an ecological view. In general, they may lack the conceptual framework or context within health services research to appreciate fully their actual or potential significance.…”

Acquisition of Small Rural Hospitals by Multihospital Systems*

“…Further diversity can be found among MHSs (Alexander, Anderson and Lewis, 1985;Studnicki, 1979). They may be sponsored by a Catholic order or some other church, publicly controlled, nonprofit or for-profit.…”
