Vibrio vulnificus can cause local wound infection, gastroenteritis, or septicemia. Case Presentation: In this case, an 86-year-old male was accidentally stabbed in the middle of his right thumb while cleaning whitewater fish and came to the emergency department with high fever and painful swelling of the right hand. Physical examination revealed hemorrhagic bullae in the right hand. Emergency surgery and bacterial culture were performed. Because of timely antibiotic use and surgical treatment, the patient eventually recovered and was discharged from the hospital. Conclusions: This case suggests that the possibility of Vibrio vulnificus should be considered in cases of severe infection of the extremities, even without a history of seafood consumption or seawater exposure. Early recognition, rational choice of antibiotic agents, and timely wound debridement can substantially improve the prognosis of patients and reduce mortality.","PeriodicalId":22109,"journal":{"name":"Surgical infections","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140712260","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compliance rates vary worldwide from 15% to 84.3%, with studies in Turkey not exceeding 35%. The aim of this multicenter study was to determine the rate of appropriate antibiotic class, timing, and duration as well as discharge prescriptions in Turkey. Thus, we aimed to determine the rate of full compliance with SAP procedures in our country Patients and Methods: This multicenter, prospective, observational, descriptive study was conducted in 47 hospitals from 28 provinces in seven different regions of Turkey. Patients over 18 years of age in all surgical units between June 6, 2022, and June 10, 2022, were included in the study. Results: Of the 7,978 patients included in the study, 332 were excluded from further analyses because of pre-existing infection, and SAP compliance analyses were performed on the remaining 7,646 cases. The antibiotic most commonly used for SAP was cefazolin (n = 4,701; 61.5%), followed by third-generation cephalosporins (n = 596; 7.8%). The most common time to start SAP was within 30 minutes before surgery (n = 2,252; 32.5%), followed by 30 to 60 minutes before surgery (n = 1,638; 23.6%). Surgical antimicrobial prophylaxis duration was <24 hours in 3,516 (50.7%) patients and prolonged until discharge in 1,505 (21.7%) patients. Finally, the actual proportion of patients compliant with SAP was 19% (n = 1,452) after omitting 4,458 (58.3%) patients who were prescribed oral antibiotic agents at discharge as part of a prolonged SAP. Conclusions: Surgical antimicrobial prophylaxis compliance rates are still very low in Turkey. Prolonged duration of SAP and especially high rate of antibiotic prescription at discharge are the main reasons for non-compliance with SAP.","PeriodicalId":22109,"journal":{"name":"Surgical infections","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140765402","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Demographic features, predisposing factors, clinical outcomes, and antibiotic agent costs were analyzed.
