Supplemental Perioperative Oxygen to Reduce Surgical Site Infection After High Energy Fracture Surgery

Primary Objective To compare the proportion of surgical site infections within 6 months in patients treated with Supplemental Perioperative Oxygen compared to those treated without Supplemental Perioperative Oxygen. Secondary Objectives To compare species and antibacterial sensitivities of the bacteria in the patients who develop surgical site infections in study patients treated with Supplemental Perioperative Oxygen compared to those treated without Supplemental Perioperative Oxygen. To validate the previously developed risk prediction model for the development of surgical site infections after fracture surgery To measure and compare resource utilization and cost associated with surgical site infection in study patients treated with Supplemental Perioperative Oxygen compared to those treated without Supplemental Perioperative Oxygen. Primary Aim: To compare the proportion of surgical site infections within 6 months in patients treated with Supplemental Perioperative Oxygen compared to those treated without Supplemental Perioperative Oxygen. Hypothesis 1: The proportion of surgical site infections will be lower for patients treated with Supplemental Perioperative Oxygen. Secondary Aim #1: Compare bacterial species and antimicrobial susceptibilities in the patients who develop surgical site infections in study patients treated with Supplemental Perioperative Oxygen compared to those treated without Supplemental Perioperative Oxygen. Hypothesis 2: In the patients who develop infections, the bacterial species and antimicrobial susceptibility profiles of those treated with Supplemental Perioperative Oxygen will be similar to those treated without Supplemental Perioperative Oxygen. Secondary Aim #2: To validate the previously developed risk prediction model for the development of surgical site infections after fracture surgery. Hypothesis 3: The previously developed RIOTS score will be highly predictive of infection risk. Secondary Aim #3: Measure and compare resource utilization and cost associated with surgical site infection in study patients treated with Supplemental Perioperative Oxygen compared to those treated without Supplemental Perioperative Oxygen. Hypothesis 4: Supplemental Perioperative Oxygen will be associated with lower resource utilization and cost.
