Risk factors for inpatient hospital admission following isolated orbital floor fractures.

Orbital floor fractures are common injuries seen in the emergency department (ED). In this study, the National Trauma Data Bank (NTDB, 2016-2017) was used to identify patients presenting with isolated orbital floor trauma. Patient-specific factors were analyzed to determine associations with management. The sample comprised 912 patients; 285 (31.3%) of these patients were discharged from the ED, 541 (59.3%) were admitted to the hospital but did not undergo an operation, and 86 (9.4%) underwent operative treatment. Pediatric patients and older patients (<18 years and>55 years) were more likely to be admitted than those aged 18-55 years, and pediatric patients were more likely to undergo an urgent operative intervention than those in the other age groups (all P < 0.001). Patients with alcohol use disorder (P = 0.002) and hypertension (P = 0.004) had increased odds of admission. Private and Medicare insurance patients were more likely to be admitted, and self-pay patients less likely (P < 0.001). Older age and Medicaid payor status showed increased odds of a greater hospital length of stay. Biological sex, race/ethnicity, functionally dependent health status, myocardial infarction, steroid use, and substance use disorder were not associated with discharge disposition. There are non-injury related, patient-specific factors that may influence the management of orbital floor fractures.
