We aimed at describing the epidemiology of femur fracture in elderly hospitalized for femur fracture in Lazio (Italy), and evaluating the association between patient's and hospital characteristics on in-hospital mortality. We conducted a population- and hospital-based study (Lazio region: 5.233.233 inhabitants) among people 65+ years aged.
Source of data: regional hospital register 2002-2003; ICD-9-CM codes for patients' selection 820 e 821. Direct standardization (rate x 1000) and logistic regression analysis (OR, 95% CI) were performed. Overall hospitalization rate in elderly was 7.5%o (10.l%o females vs. 3.9%0 males). 12.033 patients with femur fractures were enrolled in the study period; 21,6% were not treated surgically: in comparison with those who underwent surgery, they were males, residents out of Rome, older and with worst health status. In-hospital mortality rate was 7,97%. In-hospital mortality determinants were: male gender (OR=0.56), older age (85+, OR=3.30), living out of Rome (OR=0.50), comorbidities (Charlson 'index 3: OR=4.44), "others and unspecified parts of femur" as site of fracture (OR=1.84), admission to a private hospital (OR=O. 79) and a surgical treatment (OR=0.20). In conclusion, this study showed the effect of selected individual characteristics on in hospital mortality and suggested a role of early surgical treatment and access to private sector. Regional hospital information systems represent useful tools to address epidemiological impact of hip fracture and its health care resources utilization.
