title: [An epidemiological evaluation of proximal femur fracture on a population living in the area of the Florence Local Health Trust].
abstract: Proximal femur fracture is a relevant issue of public health due to its high prevalence in elderly people and high social costs. We performed an epidemiological description of the event based on the data derived from the hospital discharge reports over a 5-year period, from 1997 to 2001, referred to a mean population of 796,990 persons. During this period, the disease incidence rate, estimated on hospital admissions, is high (higher than national average), although rather constant over years: average values are 777.92/100,000 in the >65 age group, 2627.08/100,000 in the >85 age group, and 1264.25/100,000 in the 80-84 age class. Incidence rate shows an exponential increase with age starting from the age of 50 and in the elderly age classes women exhibit around twofold values. Besides, the mean length of hospitalization is higher in the elderly age classes. Regarding 4 selected kinds of surgical intervention we made and verified the hypothesis of a correlation between length of stay in hospital before the intervention and two outcome indicators: length of stay in hospital after the intervention (data fail to confirm our hypothesis) and in-hospital mortality (data confirm our hypothesis: mean length of stay in hospital before the intervention is significantly higher in the group of dead patients than in the group of home discharged patients).
