Assessment of Prophylactic Antibiotic Coverage in Culture-positive Traumatic Open Fractures.

Guidelines provide varying recommendations for the prophylactic antimicrobial treatment of open fractures. This single-center, retrospective cohort study was conducted to determine how well an institutional prophylactic antibiotic protocol covered pathogens associated with open fractures. The authors included adult trauma patients with one or more open fractures and a positive culture from the site of the open fracture, and compared outcomes between patients who were covered by prophylactic antibiotics with patients not covered by prophylactic antibiotics. Of 957 patients evaluated, 75 were included, with 40 patients (53%) covered by the prophylactic antibiotics received. Multidrug-resistant pathogens were isolated in 23 (58%) patients covered versus 26 (74%) patients not covered (p = 0.128). The median time to positive culture was less in patients not covered by initial antibiotics compared with those who were covered (30.2 vs. 102.1 days; p = 0.003). Over half of the patients developed cultures with pathogens that were covered by their initial antibiotic prophylaxis. (Journal of Surgical Orthopaedic Advances 33(2):084-087, 2024).

Pneumococcal Vaccination Rates and Associated Meningitis Events in Patients With Acute Cerebrospinal Fluid Leak.

OBJECTIVE: To characterize the institutional utilization of pneumococcal vaccination during an index hospital admission for acute cerebrospinal fluid (CSF) leakage and associated infectious and clinical outcomes. METHODS: This retrospective cohort study included patients hospitalized and treated for an acute CSF leak from January 2017 to June 2022. The primary outcome evaluated the incidence of pneumococcal vaccination during the index admission in patients without prior vaccination. Secondary outcomes evaluated the incidence of meningitis, time from CSF leak identification to meningitis, and mortality within 1 year of the index admission. RESULTS: A total of 94 patients were included. Nineteen (20.2%) patients received pneumococcal vaccination prior to admission. Of the 75 patients without prior vaccination, 4 (5.3%) patients received vaccination during the admission. Meningitis occurred in 5/94 (5.3%) patients and occurred 4-24 days from CSF leak identification. Mortality was observed in 9/94 (9.6%) patients. None of the meningitis cases were attributed to culture-positive findings of pneumococcal disease. CONCLUSIONS: The results of this study demonstrate an overall low institutional utilization of pneumococcal vaccination in patients with an acute CSF leak. Infectious and clinical outcomes reflected comparable to previous reported literature. Further evaluation into the risk-benefit relationship of vaccination omission is warranted in this patient population.
