JOURNAL CLUB PRESENTER-KARAN MIT TAL DATE-27/10/23 MODERATOR-DR.KALPA PANDYA CONTENTS INTRODUCTION AIM/PURPOSE METHODS RESULTS DISCUSSION INTRODUCTION Prophylactic antibiotics are routinely prescribed for patients with facial fractures. Risk(adverse reaction, resistance) vs benefit(reducing infectious complications) ratio must be assessed before giving antibiotics. When surveying doctors - 66% of respondents prescribe antibiotics sometimes or always for nonoperative facial fractures, while 34% responded that they never prescribe antibiotics in this scenario. It has been found that prescribing antibiotics is the default treatment of choice among surgeons in non-operative facial fractures. However recent studies have questioned the efficacy of this clinical practice. CRITICALLY ILL PATIENTS WITH FACIAL FRACTURES RISK FOR THE DEVELOPMENT OF SINUSITIS. MAXILLARY SINUSITIS VENTILATOR-ASSOCIATED PNEUMONIA (VAP) MORBIDITY AND MORTALITY IN ICU SETTINGS While recent literature suggests antibiotics are not needed in patients with nonoperative facial fractures involving sinuses, the existing studies do not focus on critically injured patients who are known to be at higher risk for sinusitis and VAP which could be exacerbated by their facial fracture. PURPOSE To determine if antibiotics reduce the rate of infectious complications in critically injured patients who have blunt midfacial trauma treated nonoperatively Hypothesis- Rate of infectious complications that arose from facial fractures with sinus involvement was similar in patients who received antibiotics and in those who did not STUDY DESIGN Retrospective cohort study Study population-Patients who were admitted to the Trauma ICU at University Medical Center in New Orleans with midfacial fractures sustained from nonpenetrating trauma between August 13, 2012, and July 30, 2020 INCLUSION CRITERIA CRITICALLY ILL ON ADMISSIONICU ADMISSION EXCLUSION CRITERIA ONLY MANDIBLE AND OR TEMPORAL BONE FRACTURE AGE > 18 YEAR UNDERWENT OPERATIVE MANAGEMENT FACIAL FRACTURE INCLUDING FRONTAL,MAXILLARY OR ETHMOID SINUS NON-OPERATIVE MANAGEMENT DIED WITHIN 5 DAYS OF ADMISSION VARIABLES Primary predictor variable- Antibiotic administered or not--------considered to have been treated with antibiotics if they received at least 2 doses of antibiotics within that 7-day period Primary outcome variable - Development of one or more of the following complications: sinusitis, soft tissue infection at the fracture site, or any type of pneumonia, including ventilator associated pneumonia Secondary outcome variables - Development of each specific complication, such as ventilator-associated pneumonia, any other form of pneumonia, or Clostridioides difficile infection Other variables recorded - Age, gender, race, Glasgow Coma Scale (GCS) on arrival, Injury Severity Score, the presence of lacerations or foreign bodies around the fracture site, packed red blood cell (pRBC) transfusion (measured in number of units administered), and hospital length of stay (in days) RESULTS 307 patients met the inclusion criteria. Mean age - 40.6 years and 85.0% of patients were men. Facial lacerations were noted in 34.5%. Of the 307 patients, 229 (74.6%) were administered antibiotics. Patients were more likely to receive antibiotics if they had a higher Injury Severity Score , facial lacerations , increased pRBC transfusions , and a longer hospital length of stay Complications developed in 13.6% of patients. These complications included: sinusitis (0.3%), ventilator-associated pneumonia (7.5%), and other pneumonia types (5.9%). C difficile colitis developed in 2 patients (0.6%) in this cohort. There were no soft tissue infections overlying the fractures in the study population. Patients with complications were more likely to have a lower GCS on arrival (P < .001), a higher Injury Severity Score (P < .001), received more units of pRBCs (P < .001), and a longer hospital stay (P < .001) Antibiotic administration was not associated with the development of complications. The complication rate was 13.1% in patients who received antibiotics was and 15.4% in those who did not AFTER ADJUSTING FOR RACE, PRESENCE OF LACERATIONS AND FOREIGN BODIES, AND GCS, ANTIBIOTIC ADMINISTRATION WAS STILL NOT STATISTICALLY SIGNIFICANTLY ASSOCIATED WITH COMPLICATIONS FURTHERMORE, NONE OF THE SECONDARY OUTCOMES VARIABLES (SINUSITIS, VAP, OTHER PNEUMONIA TYPES, AND C DIFFICILE INFECTION) WERE ASSOCIATED WITH ANTIBIOTIC ADMINISTRATION DISCUSSION The authors hypothesized that treatment with antibiotics would not reduce the rate of infectious complications. The results of this study support their hypothesis that antibiotics for nonoperative facial fractures do not reduce the rate of infectious complications. The rate of sinusitis was exceedingly low (0.3%). Pneumonias, which were postulated to be linked to sinusitis and facial fractures, occurred at no different rates regardless of antibiotic use in either the adjusted or unadjusted analysis. In the study population, facial fractures do not appear to be a significant risk factor for sinusitis regardless of antibiotic administration. Additionally, C difficile colitis occurred at a rate of about 0.9% in the antibiotic group in this study There were a number of variables measured which were correlated with both the predictor, antibiotic use, and the outcome, complications. These variables, length of stay, GCS, Injury Severity Score, and total blood infusions are all markers for severity of trauma. More severely injured patients were more likely to have complications and receive antibiotics related to one of their injuries. In the adjusted analysis, only GCS was retained in the model, likely because of its relatively high correlation to the other variables but better correlation with infectious complications The findings of this study are in agreement with that of Malekpour et al, which also showed no benefit from antibiotics for nonoperative fractures with sinus involvement, though they did not examine critically injured patients specifically. Their study also found no incidence of soft tissue infections, but did not evaluate sinusitis or pneumonia. C difficile colitis was again found only in the antibiotic group, but not with sufficient prevalence to reach statistical significance. Zosa et al came to similar conclusions when they evaluated the use of prophylactic antibiotics in critically ill patients with facial fractures. Their study compared patients receiving less than 24 hours of antibiotics to patients that received longer than 24 hours of antibiotics. They found no significant difference in the rate of head and neck infections between groups in patients with nonoperative facial fractures. Unlike this study, theirs included penetrating trauma and mandible fractures. Pessino et al, zygomaticomaxillary complex fractures, orbital fractures, and zygomatic arch fractures managed nonoperatively without antibiotics in a large case series showed not a single incident of soft tissue infection or sinusitis. Their results are consistent with the present study, although they did not include critically injured patients. Esce et al, for nonoperative orbital fractures, there were no infectious complications in either an antibiotic group or a group that did not receive antibiotics In summary, regardless of fracture type or population, nonoperative midfacial fractures that develop infections are exceedingly rare. Though the present study is the first to examine critically injured patients and to measure pneumonia rates, the findings mirror the previously published data that examined this question specifically The results of the present study support the hypothesis that intervening prophylactically with antibiotics for facial fractures does not change the risk of sinusitis or feared infectious sequelae of sinusitis in the intubated patient, such as VAP MERITS AND DEMERITS MERIT • Sample Size • Multiple variables • Critically injured patients DEMERIT • Retrospective study • Systemic co-morbids • Type/Extent of fracture • Subjective bias • Reproducibility THANKYOU
