Multivariate analysis for risk of complication after femur fracture repair using binary logistic regression
| Adjusted OR for complications (95% CI) | P value | |
| Sex (female) | 0.76 (0.39 to 1.49) | 0.42 |
| Age (per year increase) | 1.04 (1.01 to 1.07) | 0.003 |
| Elixhauser score >2 | 3.45 (1.75 to 6.80) | <0.001 |
| Fixation performed >24 hours after trauma center admission | 2.08 (1.1 to 4.1) | 0.04 |
| Transfer time (per hour increase) | 0.94 (0.80 to 1.09) | 0.41 |
When including patients’ age, sex, presence of more than 2 comorbidities on the Elixhauser score, and time to fixation greater than 24 hours, we found that age, comorbidities, and delayed repair of fracture were independent risk factors for complications. Transfer time was not associated with increased risk of complications in this model.
