Delay in Surgical Débridement of Open Tibia Fractures: An Analysis of National Practice Trends

Abstract

BACKGROUND: Débridement and irrigation (D&I) of open tibia fractures less than 6 hours from the time of injury has been promoted as orthopaedic dogma despite limited evidence. The goal of this study was to determine the duration between emergency room presentation and D&I in open tibia fractures and to examine factors associated with delay in treatment. METHODS: The National Trauma Data Bank Version 3.0 identified 6099 blunt trauma patients with open tibia fractures. Time was calculated from emergency room arrival to first D&I. Risk factors associated with delay in treatment greater than 6 hours and greater than 24 hours were then calculated using univariate and multivariate statistical methods. RESULTS: Median time to D&I was 4.9 hours. Forty-two percent of patients with open tibia fractures experienced a delay in treatment of greater than 6 hours and 24% of patients experienced a delay to treatment of greater than 24 hours. Risk factors associated with greater than 6- and 24-hour delay on univariate and multivariate logistic regression were age, head or thoracic injury with Abbreviated Injury Score greater than 2, and presentation between 6 pm and 2 am. Level I and university hospitals carry a greater risk of delay that was independent of injury severity in multivariate analysis. CONCLUSIONS: A significant percentage of patients with open tibia fractures undergo their first surgical intervention of D&I greater than 6 hours after presentation to the emergency room. Patients with delayed D&I have more severe injuries, are treated at university or Level I centers, and present later in the day.
