[Evolution of functional autonomy in geriatric medium-term care units: a reliable performance indicator?].

The objective of this study was to compare the evolution of the level of functional dependence of patients between the time of their hospital admission and release following treatment received in the geriatric medium-term care units, in order to propose this variable as a clinical performance indicator for this type of service. The differential score of physical dependence observed was determined for each hospital stay, and the adjusted significant functional improvement rate (SFI) was calculated for every unit. This adjusted SFI rate was then compared to the overall rate of all of the units combined. The overall SFI rates were 23% in 2004. Seven of the 49 units studied present an adjusted rate significantly inferior to the average rate of the total number of units combined. This study constitutes one of the first performance analyses in the medium-term sector, and the adjusted SFI rate seems to be a pertinent and reliable indicator within this framework.
