Proxy case mix measures for nursing homes.
Nursing home case mix measures are needed for the same purposes that spurred the intensive development of case mix measures for hospitals: management and planning decisions, organizational performance research, and reimbursement policy analysis. This paper develops and validates a pair of complementary measures that are simple to compute, are easy to interpret, and use generally available data. They are not, however, definitive. A secondary purpose of this paper is thus to galvanize the development of data bases that will give rise to superior case mix measures for nursing homes.
