RESUMO
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).

BACKGROUND: Remdesivir and sotrovimab both have clinical trial data in the outpatient setting demonstrating reduction in the risk of hospitalizations and emergency department (ED) visits related to COVID-19. OBJECTIVES: To evaluate the effectiveness of remdesivir in comparison with sotrovimab and matched high-risk control patients in preventing COVID-19-related hospitalizations and ED visits during the Omicron B.1.1.529 surge. PATIENTS AND METHODS: This retrospective cohort study included outpatients positive for SARS-CoV-2, with non-severe symptoms for ≤7â days and deemed high-risk for severe COVID-19 by an internal scoring matrix. Patients who received remdesivir or sotrovimab from 27/12/2021 to 04/02/2022 were included (nâ=â82 and nâ=â88, respectively). These were compared with a control cohort of high-risk COVID-19 outpatients who did not receive therapy (nâ=â90). The primary outcome was a composite of 29â day COVID-19-related hospitalizations and/or ED visits. Pre-specified secondary outcomes included components of the primary endpoint, 29â day all-cause mortality and serious adverse drug events. RESULTS: Patients treated with remdesivir were significantly less likely to be hospitalized or visit the ED within 29â days from symptom onset (11% versus 23.3%; ORâ=â0.41, 95% CIâ=â0.17-0.95). Patients receiving sotrovimab were also less likely to be hospitalized or visit the ED (8% versus 23.3%; ORâ=â0.28, 95% CIâ=â0.11-0.71). There was no difference in the incidence of hospitalizations/ED visits between sotrovimab and remdesivir. CONCLUSIONS: Our highest-risk outpatients with Omicron-related COVID-19 who received early sotrovimab or remdesivir had significantly lower likelihoods of a hospitalization and/or ED visit.
