Factors Associated With Loss to Follow Up After Temporal Bone Fracture.

Introduction: Inpatient and outpatient evaluation is important for management of temporal bone trauma due to the possible otologic complications that can result. However, there is limited literature on follow up rates following temporal bone fracture. This study aimed to determine the proportion of patients lost to follow up after sustaining temporal bone fractures and identify factors associated with loss to follow up.

Methods: Retrospective review of adult patients who sustained temporal bone fractures at a level I trauma center from January 1, 2019 to January 1, 2024 was completed (IRB H-44161). The primary outcome included prevalence of patient loss to follow up. Secondary variables included initial radiographic and exam findings, otologic complications, and demographic characteristics. Patients who were seen in follow up and lost to follow up were compared, and odds of loss to follow up was calculated.

Results: Sixty-nine patients met inclusion criteria for this study, of which 30 patients (43.5%) were lost to follow up. Patients who were White had a significantly lower odds of loss to follow up than those who were not White (OR = 0.2506 (95% CI: 0.0706, 0.8067, P = .0024). While need for acute management was not significantly different between the groups, a significantly lower proportion of patients who were intubated on presentation (P = .0091), had abnormal otoscopic exam (P = .0211), and had otologic complications (P = .0056) were lost to follow up.

Conclusion: Almost half of patients who sustained temporal bone fractures, including a significantly higher odds of minority race/ethnicity patients, were lost to follow up.
