The contribution of open extremity fractures to infection in multiply injured patients.

Abstract

We sought to determine whether a contaminated open fracture was a reliable component for calculating the Outcome Predictive Score in patients with multiple injuries. We studied 41 patients whose primary source of contamination was open extremity fractures. Only one of the 41 patients developed osteomyelitis. The rate of infection from an open fracture is minimal in the multiply injured patient. Inclusion of patients with open fractures in studies that assess the likelihood of infection and the value of anti-infective agents incorrectly identified patients for clinical trials and results in an overestimation of survival based on the Outcome Predictive Score. These findings suggest that open fractures should be excluded as an entry criterion in future clinical trials.
