Time of Brain Imaging In Patients With An Acute Traumatic Intracranial Haemorrhage

Abstract

Background We observed variation in timing of CT brain imaging in patients presenting with a history of trauma. The objective of this audit was to determine adherence to local ED CT Head Criteria in patients with a confirmed traumatic ICH. Methods Retrospective point prevalence audit of patients with a confirmed intracranial haemorrhage over a five-month period using our neurotrauma work-stream data. Exploration of CT timing between Criteria A (within 60 minutes) and Criteria B (within 8 hours). Characteristics reviewed included Gender, Age, Time of presentation to ED, Day of Arrival, GCS on presentation, Mechanism of Injury and Time of CT completion. Results 68 patients over the five-month period had a confirmed ICH: 48 male, 20 female. The median age was 62 years (range 17-97). Falls of less than 2 metres were the most frequent cause of injury (n=44, 65%), with 60% of these occurring in patients aged over 65 years of age. 67% (n=31) of patients meeting Criteria A did not have a CT Brain completed within 60 minutes. 14% (n=3) of patients meeting Criteria B did not have a CT Brain completed within 8 hours. Of patients meeting criteria who did not have a timely CT, 11 patients presented out of hours. Patients aged less than 65 years of age were less likely to meet target CT timing; 71% (n=24). Conclusion This audit highlights that only 33% of patients meeting Criteria A had brain imaging within one hour. Older adults were more likely to meet target CT timing than younger adults. Lack of ED access to radiology out of hours was deemed to be the main barrier to meeting target CT timing. We are working alongside our radiology department to secure no discussion trauma CT scans in ED out of hours. We plan to re-audit following the implementation of this change.
