Abstract
Timing of mandibular fracture repair has long been debated. The purpose of the present study was to assess the incidence of postoperative inflammatory complications (POICs) following open repair of mandibular fractures managed non-urgently in the outpatient setting versus urgently in the inpatient setting. The authors utilized the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database to enroll a sample of patients with mandibular fractures who underwent open repair. The primary independent variable was treatment protocol: outpatient (elective) versus inpatient (urgent/non-elective). The primary dependent variable was POIC (yes/no). Descriptive, bivariate, and multiple logistic regression statistics were utilized to evaluate the relationship between treatment protocol and POICs. The study cohort was comprised of 1,848 subjects with 1,134 outpatients and 714 inpatients. The incidence of POICs was 6.53% for the outpatient group compared to 8.96% for the inpatient group, with no significant difference between groups (P= .052). However, subjects treated as inpatients were 1.51 times more likely to experience any complication (P=.008) due to an increase in non-POICs (P=.028), in particular urinary tract infections (P=.035). After adjusting for age, hypertension requiring medical treatment, and smoking, classification as ASA II (P=.046, OR=2.21, 95% CI 1.01 to 4.83), ASA III (P=.020, OR=2.88, 95% CI 1.18 to 7.02), diabetes (P=0.004, OR=3.11, 95% CI 1.43 to 6.74), and preoperative hematocrit (P=0.010, OR=0.950, 95% CI 0.913 to 0.988) were independent predictors of POICs. Length of stay was 0.83 ± 2.61 days compared to 2.36 ± 3.63 days for the outpatient and inpatient groups, respectively (P ≤ .001). There was no significant difference in POICs between patients treated as outpatients versus inpatients, though outpatients had fewer non-POICs and a shorter length of hospital stay.
