Abstract Introduction Inpatient falls are associated with serious and life–threatening injuries in 4-6% of cases1. This includes Intracranial Injury (ICI). Imaging of the Head is required to detect and manage patients with head injury2; however there are no specific guidelines to facilitate utilisation of Head CT after Inpatient Falls. Objective The goal of this study is to review the utilisation of Head CT to determine rates of intracranial injury (ICI) following inpatient falls. Methodology This is a retrospective study of all patients admitted to the Medical Department, HKL in year 2017 who sustained an inpatient fall. The data was obtained from the database of the Falls Team HKL and review of medical notes. Results 152 patients, with an average age of (61.65±15.51) years were included in this study. Of these 94 (61.8%) were male, 85 (55.9%) were ≥ 65 years. 45 (29.6%) patients had a Head CT after inpatient fall. Median time to request for Head CT was 130 (IQR 30–582.50) minutes from the time of fall. Head CT was more likely in patients with Direct impact to head during fall (Adj.OR;4.71(95%CI 1.39 – 15.85). Fifty-seven (37.5%) patients sustained Direct impact to head during fall, however only 32/57(71.1%) had a Head CT as inpatient. Patients who had Direct impact to head during fall, were more likely to develop Giddiness (Adj.OR;5.96(95%CI 1.94-18.30) and Hematoma (Adj.OR;6.186(95%CI 1.59 – 24.03) after fall. Intracranial injury (ICI) was identified in 5/45 (11.1%) patients who underwent a Head CT. Patients with (ICI) had an average age of (74.00 ±7.906) years. All 5 patients were reviewed by the Neurosurgical team. Of these, 1/5 (20%) patient died during hospitalisation and 1/5 (20%) patient was discharged in a terminally ill condition. Conclusion Intracranial injury (ICI) was identified in 5/45 (11.1%) patients who underwent a Head CT and they were more likely to be ≥ 65years. Head CT was more likely in patients with Direct impact to head, headache, hematoma and confusion after inpatient fall.
