Data including demographic characteristics, mechanism of injury, type of presentation (e.g., primary or transfer), treatment plan, and time to intervention were recorded.</p><p><strong>Objective: </strong>Mandibular fractures are common traumatic injuries. Because these injuries are managed by surgical specialists, these patients are often emergently transferred to tertiary care hospitals. This study aims to assess the benefits of emergent transfer in this patient group.</p><p><strong>Methods: </strong>Variables were summarized using descriptive statistics. The relationship with initial disposition was assessed via tests of association, including Student's <i>t</i>-test, Fisher's exact test, or chi-square tests. Significance was set to <i>p</i> values less than 0.05. Multivariate regression analysis was conducted to determine predictors of presentation to outside hospital followed by transfer to our institution.</p><p><strong>Results: </strong>Records from 406 patients with isolated mandibular fractures were evaluated. 145 (36%) were transferred from an outside hospital specifically for specialty evaluation.

However, when isolated mandible fractures were evaluated, only one patient required intervention in the ED. Patients with grossly open fractures and pediatric patients were more frequently admitted specifically for operative management. This practice of acute interfacility transfer represents an unnecessary cost to our health system as isolated mandible fractures can be managed on an outpatient basis. We suggest that pediatric patients and patients with open fractures be transferred for urgent evaluation and management, whereas most patients would be appropriate for outpatient evaluation.</p>","PeriodicalId":50460,"journal":{"name":"Exploration Geophysics","volume":"6 1","pages":"40-46"},"PeriodicalIF":0.9,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10874203/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81149402","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
