“…Worryingly, only 23.1% (81/351) of our identified cohort with a confirmed mTBI diagnosis (ie, meeting the WHO criteria) had an accurate mTBI diagnosis documented in the medical records (ie, written diagnosis of ‘concussion’, ‘mTBI’). The proportion of accurate diagnoses was much lower than reported in two previous prospective studies conducted in Canada6 and the USA,7 respectively, being ≥50%. While using a retrospective design could account for these differences, global challenges certainly exist in the acute identication of ‘minor’ TBI events.…”

“…Little information exists, however, about the accuracy of mTBI identification in emergency settings. Two studies, conducted in three Canadian EDs6 and two EDs in the USA,7 found that up to 50% of patients sustaining mTBI received an inaccurate ED diagnosis. Poor identification likely impacts clinical management of these patients.…”

“…Although the patients were typically asked about LOC, other symptoms typical of concussion such as confusion were not assessed. In a Canadian prospective ED study of 250 adults, 16% were not diagnosed with concussion despite meeting criteria 14 . In a retrospective Australian ED study of 351 adults, only 23.1% with confirmed mTBI had this diagnosis clearly recorded in the medical notes 15 .…”

“…The number of TBIs may have been underestimated by using ICD codes to identify TBIs, as a Canadian study reported that one in six patients with concussion signs and symptoms were misdiagnosed in emergency departments. 78 Additionally, TBIs may have been underestimated by counting diagnoses given within a 30-day period as one TBI. This was done because physicians were required to record a diagnosis each time they saw a patient.…”
