Using short-stay trim points to identify potential CMG design improvements

The cost distribution of short-stay cases, and the extent to which this cost distribution differs from that of typical cases, will be reviewed. The clinical and demographic profiles of cases identified as short stay will, as well, be appraised. Correlation of short-stay cases with specific clinical attributes may indicate that the CMG is a candidate for redesign (e.g., a split or redefinition). The incidence of short-stay cases by hospital, and stratum of hospitals, will be assessed to determine whether short-stay cases affect some hospitals differently. A correlation of short-stay cases with certain hospitals may suggest variations in practice patterns.
