RESUMO
The lowering number of physiotherapists c/o surgery departments of Orthopaedic Institute Gaetano Pini of Milan, required the application of a new organizational model based on the centralization of government activities, in order to optimize employment of staff. A programming and reporting tool was developed throught a database. The collected data (from January to December 2013) related to the reported physiotherapists activities were analysed and matched to operating theater's activities in order to find the correlation value. The results are lined up the hypothesis stated in the planning phase of the organizational model's project (in absence of hystorical referral). Correlation between Physiotherapists and Operation Theather's activities was good (r=0.59), giving us a reliable predictional model. This study has some limitations mostly related to the resistence expressed by employees in the change management.
