Head home: implementation during COVID-19 pandemic.

BACKGROUND: Recent research suggests that between 20% and 50% of paediatric head injuries attending our emergency department (ED) could be safely discharged soon after triage, without the need for medical review, using a 'Head Injury Discharge At Triage' tool (HIDAT). We sought to implement this into clinical practice. METHODS: Paediatric ED triage staff underwent competency-based assessments for HIDAT with all head injury presentations 1 May to 31 October 2020 included in analysis. We determined which patients were discharged using the tool, which underwent CT of the brain and whether there was a clinically important traumatic brain injury or representation to the ED. RESULTS: Of the 1429 patients screened; 610 (43%) screened negative with 250 (18%) discharged by nursing staff. Of the entire cohort, 32 CTs were performed for head injury concerns (6 abnormal) with 1 CT performed in the HIDAT negative group (normal). Of those discharged using HIDAT, four reattended, two with vomiting (no imaging or admission) and two with minor scalp wound infections. Two patients who screened negative declined discharge under the policy with later medical discharge (no imaging or admission). Paediatric ED attendances were 29% lower than in 2018. CONCLUSION: We have successfully implemented HIDAT into local clinical practice. The number discharged (18%) is lower than originally described; this is likely multifactorial. The relationship between COVID-19 and paediatric ED attendances is unclear but decreased attendances suggest those for whom the tool was originally designed are not attending ED and may be accessing other medical/non-medical resources.

Head home: a prospective cohort study of a nurse-led paediatric head injury clinical decision tool at a district general hospital.

OBJECTIVES: To assess if a nurse-led application of a paediatric head injury clinical decision tool would be safe compared with current practice. METHODS: All paediatric (<17 years) patients with head injuries presenting to Frimley Park Emergency Department (ED), England from 1 May to 31 October 2018 were prospectively screened by a nurse using a mandated electronic 'Head Injury Discharge At Triage' questionnaire (HIDATq). We determined which patients underwent CT of brain and whether there was a clinically important intracranial injury or re-presentation to the ED. The negative predictive value of the screening tool was assessed. We determined what proportion of patients could have been sent home from triage using this tool. RESULTS: Of the 1739 patients screened, 61 had CTs performed due to head injury (six abnormal) with a CT rate of 3.5% and 2% re-presentations. Of the entire cohort, 1052 screened negative. 1 CT occurred in this group showing no abnormalities. Of those screened negative, 349 (33%)/1052 had 'no other injuries' and 543 (52%)/1052 had 'abrasions or lacerations'. HIDATq's negative predictive value for CT was 99.9% (95% CI 99.4% to 99.9%) and 100% (95% CI 99.0% to 100%) for intracranial injury. The positive predictive value of the tool was low. Five patients screened negative and re-presented within 72 hours but did not require CT imaging. CONCLUSION: A negative HIDATq appears safe in our ED. Potentially 20% (349/1739) of all patients with head injuries presenting to our department could be discharged by nurses at triage with adequate safety netting advice. This increases to 50% (543/1739), if patients with lacerations or abrasions were given advice and discharged at triage. A large multicentre study is required to validate the tool.
