Abstract

The development of techniques for the measurement of hospital output is one of the primary issues facing health service researchers. Scales must be developed which can be used to categorize patients in such a way that homogeneity within patient groups and heterogeneity between patient groups, with respect to the nature of their illness, is maximized. Such a categorization scheme, which must allow for the assessment of the severity of illness can then be used for studies of hospital utilization and costs; development of equitable reimbursement mechanisms for hospitals; and for clinical trails designed to test the efficacy of different treatment modalities.
