The estimate of clinical outcomes by Rasch analysis

Abstract

This study describes and analyses the optimal property that the proposed methods of latent variables estimation should have to guarantee the availability of objective perform-ance measures in the case of evaluation of institutional initiatives and/or of a set of agents that offer a public service (Hospitals, Schools, etc). In particular the Rasch model will be assessed and subsequently it will be applied to the objective measurement of the cognitive status dependency regarding a sample of elderly patients involved in a plan of Regione Lombardia, named Buono Socio Sanitario, consist-ing in an economic contribution to the families that decide to attend the not self-sufficient elderly in family, as an alternative to the shelter in Residences.
