Because hip fracture incidence rises with ageand the elderly population will increase dramatically in the coming decadeswe can expect continued growth in the annual number of hip fractures.Objective: To compare the hip fracture incidence and mortality rates with those of Western countries. To identify the risk factors that associated with mortality after hip fracture.Materials and Methods: Hip fracture patients admitted to Chung Shan Medical &Dental College Hospital during the period of 1992-1996 were collected using discharge data. Variables of interest included demography, principal injuriesdiagnoses, E-code, year, type of fracture, type of operation, time between fracture and operation, number of comorbid diagoses.Results: Hip fracture rate (per 1000 first admissins) increasd for males from3.8 for ages 60-64 to 53.1 for ages 85 and over and for females from 9.4 forages 60-64 to 86.7 for ages 85 and over. The proportion of patients who died were 5.4%, 6.4% and 7.1% within one, three, and 12 months after hip fracture were respectively. Factors associated with one year mortality were elder inage, external cause due to falls, extracapusular fracture type, no peration, and 3 and more comorbid diagnoses remain statistically significantly, with relative odds (RO) of dying for those with 3 and more comorbid diagnosesveresus those with 2 and less were 6.8 with 95% confidence interval (CI) 1.8-16.4. The RO of dying among patients with comorbid diagnoses of cardiovascular diseases were 4.7 (95% cI 1.4-16.3). Conclusions: The resultsof the study suggest that the prevention of hip fracture in elderly populationand careful treatment of multiple comorbid patients after hip fracture remain an important challenge to clinicians. key words: Hip fracture, mortality
