A systematic review and meta-analysis searched observational studies and limited trial data on open fracture care, assessing whether initial debridement timing is associated with subsequent infection. Across 84 studies, later debridement showed higher surgical site infection risk, with clear critical thresholds at 12 and 24 hours, especially for high-grade fractures.","COPYRIGHT 􀀁 2020 BY THE JOURNAL OF BONE AND JOINT SURGERY, INCORPORATED  \nA commentary by Patrick C.

Coles, MD, Anthony Bozzo, MD, MSc, Andrew Furey, MD, Ross Leighton, MD,  \nand the GOLIATH Investigators*  \nInvestigation performed at McMaster University, Hamilton, Ontario, Canada  \nBackground: Open fractures are one of the leading causes of disability worldwide. The threshold time to debridement that reduces the infection rate is unclear.  \nMethods: We searched all available databases to identify observational studies and randomized trials related to open fracture care. We then conducted an extensive meta-analysis of the observational studies, using raw and adjusted estimates, to determine if there was an association between the timing of initial debridement and infection.  \nResults: We identified 84 studies (18,239 patients) for the primary analysis. In unadjusted analyses comparing various“late” time thresholds for debridement versus “early” thresholds, there was an association between timing of debridement and surgical site infection (odds ratio [OR] = 1.29, 95% confidence interval [CI] = 1. 11 to 1 .49, p \u003C 0 .001, I2 = 30%, 84 studies, n = 18,239) . For debridement performed between 12 and 24 hours versus earlier than 12 hours, the OR was higher in tibial fractures (OR = 1.37, 95% CI = 1.00 to 1 .87, p = 0.05, I2 = 19%, 12 studies, n = 2,065), and even more so in Gustilo type-IIIB tibial fractures (OR = 1.46, 95% CI = 1. 13 to 1 .89, p = 0.004, I2 = 23%, 12 studies, n = 1,255) . An analysis of Gustilo type-III fractures showed a progressive increase in the risk of infection with time. Critical time thresholds included 12 hours (OR = 1.51, 95% CI = 1.28 to 1 . 78, p \u003C 0 .001, I2 = 0%, 16 studies, n = 3,502) and 24 hours (OR = 2. 17, 95% CI = 1. 73 to 2 . 72, p \u003C 0 .001, I2 = 0%, 29 studies, n = 5,214) .  \nConclusions: High-grade open fractures demonstrated an increased risk of infection with progressive delay to debridement. Level of Evidence: Prognostic Level IV. See Instruction for Authors for a complete description of the levels of evidence.  \nAn epidemic rise in the number of open fractures is  \noccurring worldwide, particularly in low and middle  \nincome countries (LMICs) 1-4. Because of their health and economic impact, open fractures were recognized by the Lancet Commission on Global Surgery in 2015 as 1 of the top 3 surgical priorities, known as the “bellwether procedures.”5-7 Approximately 6 billion people have limited access to these procedures, leading to 1.2 million potentially preventable complications each year that could be reduced with better access to surgery8-16.  \nThe treatment of open fractures involves removal of contamination, excision of devitalized tissue, and irrigation of the wound in an attempt to reduce the risk of subsequent infection. Investigating time to surgical debridement of open fractures as an independent risk factor in the etiology of infection is challenging17-27. Current reports and systematic reviews have pooled all open fracture types, leading to a potential confounding effect on reported estimates28-30. It is possible that the most severe fractures with the worst prognosis are debrided earlier, and less severe injuries are debrided later, leading to  \n*The GOLIATH Investigators are listed in a Note
