The objective of this study was to assess the cost effectiveness of alternative treatment algorithms for the management of isolated mandibular fractures. This is an institutional review board-approved retrospective study consisting of a chart review of 25 patients who underwent operative repair of an isolated mandible fracture between July 1, 1999, and June 30, 2000. Patients were stratified into two groups: patients who were immediately admitted to the hospital from the emergency department (ED) versus patients who were discharged from the ED and who returned for elective scheduled operative repair. Patients' total hospital charges were compared on the basis of operating room (OR) time, operative materials, and hospital charges. Seventeen of the study patients were directly admitted from the ED, and eight underwent elective scheduled operative repair. Of the patients directly admitted from the ED, the mean age was 34.9 years (range, 19-57 years), and the study population consisted of 16 men and 1 woman. This group had a mean OR time of 161 minutes, a mean OR time charge of $1,978.66, a mean OR supply charge of 1,049.43 US dollars, a mean hospital floor charge of 5,041.02 US dollars, and an average hospital stay of 2.82 days. The treatment group of patients undergoing scheduled operative repair (n = 8) had a mean age of 30.3 years (range, 19-49 years), and all were men. This second treatment group had a mean OR time of 167.1 minutes, a mean OR time charge of 2,162.03 US dollars, a mean OR supply charge of 871.00 US dollars, a mean hospital floor charge of 2,759.38 US dollars, and a mean hospital stay of 0.88 days. Comparison of the two study groups demonstrated operative charges were made on the basis of time and materials and were shown to have no statistically significant difference (p = 0.753 and p = 0.289, respectively). Comparison of hospital charges revealed that patients admitted directly from the ED had a mean charge 2,276.70 US dollars higher (p = 0.019) and stayed 1.95 days longer in the hospital than patients discharged from the emergency department who returned for elective scheduled repair. There were two complications in the study patients; both occurred in the group admitted directly from the emergency room. The results of this study indicate that the most cost-effective management of an isolated mandibular fracture is initial evaluation in the ED with elective interval operative repair. This management protocol is, of course, only applicable if the patient is clinically stable and has no other injuries or comorbidities necessitating in-hospital observation.
