Objective: A handheld device using near-infrared technology (Infrascanner) has shown good accuracy for detection of traumatic intracranial haemorrhages in adults. This study aims to determine the feasibility of use of Infrascanner in children with minor head injury (MHI) in the Emergency Department (ED). Secondary aim was to assess its potential usefulness to reduce CT scan rate. Methods: Prospective pilot study conducted in two pediatric EDs, including children at high or intermediate risk for clinically important traumatic brain injury (ciTBI) according to the adapted PECARN rule in use. Completion of Infrascanner measurements and time to completion were recorded. Decision on CT scan and CT scan reporting were performed independently and blinded to Infrascanner results. Results: Completion of the Infrascanner measurement was successfully achieved in 103 (94%) of 110 patients enrolled, after a mean of 4.4 ± 2.9 minutes. A CT scan was performed in 18 (17.5%) children. Only one had an intracranial haemorrhage, that was correctly identified by the Infrascanner. The exploratory analysis showed a specificity of 93% (95%CI, 86.5-96.6) and a negative predictive value of 100% (95%CI, 81.6-100) for ciTBI. The use of Infrascanner would have led to avoid 10 CT scan, reducing the CT scan rate by 58.8%. Conclusions: Infrascanner seems an easy-to-use tool for children presenting to the ED following a MHI, given the high completion rate and short time to completion. Our preliminary results suggest that Infrascanner is worthy of further investigation as a potential tool to decrease the CTscan rate in children with MHI.

Abstract

Objective: A handheld device using near-infrared technology (Infrascanner) has shown good accuracy for detection of traumatic intracranial haemorrhages in adults. This study aims to determine the feasibility of use of Infrascanner in children with minor head injury (MHI) in the Emergency Department (ED). Secondary aim was to assess its potential usefulness to reduce CT scan rate. Methods: Prospective pilot study conducted in two pediatric EDs, including children at high or intermediate risk for clinically important traumatic brain injury (ciTBI) according to the adapted PECARN rule in use. Completion of Infrascanner measurements and time to completion were recorded. Decision on CT scan and CT scan reporting were performed independently and blinded to Infrascanner results. Results: Completion of the Infrascanner measurement was successfully achieved in 103 (94%) of 110 patients enrolled, after a mean of 4.4 ± 2.9 minutes. A CT scan was performed in 18 (17.5%) children. Only one had an intracranial haemorrhage, that was correctly identified by the Infrascanner. The exploratory analysis showed a specificity of 93% (95%CI, 86.5-96.6) and a negative predictive value of 100% (95%CI, 81.6-100) for ciTBI. The use of Infrascanner would have led to avoid 10 CT scan, reducing the CT scan rate by 58.8%. Conclusions: Infrascanner seems an easy-to-use tool for children presenting to the ED following a MHI, given the high completion rate and short time to completion. Our preliminary results suggest that Infrascanner is worthy of further investigation as a potential tool to decrease the CTscan rate in children with MHI.
