Pharmaco-economic issues in the treatment of severe osteoporosis.

INTRODUCTION: clinical guidelines recommend to identify and treat people at high risk of fracture. METHODS: we have carried out a simulation concerning pharmaco-economic issues in the treatment of severe osteoporosis and particularly those people with previous femoral fragility fractures, assuming that only 13.1% of hip fractured patients had started a proper antifracture therapy, as shown by the analysis of the Tuscany regional database. RESULTS: Annual costs sustained by the Italian healthcare system for treating hip fractured patients all over Italy have been estimated to range from 2 560 000 in year 2000 to 3 291 750 in year 2005, representing only 0,3% of the overall costs sustained because of hip fractures in Italy. CONCLUSIONS: Sixty percent of the pharmacological costs can be considered as ineffective from a therapeutic point of view because patients were assuming their drugs only for 6 months. There is a need for specific codification of osteoporotic fragility fractures at hospital admissions and for implementing regional strategies aimed to reduce hip re-fractures by increasing the number of patients on treatment and incrementing adherence to treatment.
