title: Pelvic Fracture and Risk Factors for Mortality: A Population-Based Study in Taiwan.
abstract: OBJECTIVE
  To study the incidence, demographics, distribution of fracture sites, associated injuries, and risk factors for the outcomes of pelvic fracture on a population basis.
  
  
  METHODS
  An annual claim dataset from 2001 to 2003 was retrieved from the Bureau of National Health Insurance (BNHI) trauma database with any International Classification of Diseases, 9th revision, Clinical Modification (ICD-9-CM) coded as pelvic fracture. Statistical analyses were conducted to discover the association between variables such as age, gender, month of injury, injury mechanisms, associated injuries, and outcome.
  
  
  RESULTS
  Pelvic fracture was diagnosed in 10,109 patients (4,693 males, 46.4%) and 384 patients (3.8%) died. The incidence was 14.97/100,000 person-years. The mean length of stay was 9.3 days (females, 8.8 days; males, 9.9 days; p < 0.01) and the average cost per patient was US$1,475. Both were affected by age, gender, and hospital accreditation level and ownership. There were more female cases in the age groups over 44 years old. Head injury (excluding concussion), associated chest and abdominal injuries, open pelvic fracture, and the transfusion of more than four units of blood significantly increased the risk of mortality.
  
  
  CONCLUSIONS
  The incidence rate of pelvic fracture was higher in females over 44 years of age, but the average medical resource use was higher in males. Associated injuries were stronger positive factors for the risk of mortality than gender, fracture sites, injury mechanisms, and the characteristics of the treating hospitals.
