“…As a result, calculations were required to convert some study data to the standardised method for injury reporting to enable pooled analysis to be conducted. The mean costs per concussion injury have been reported in several studies [52][53][54][55][56]. Only two of these studies have specifically reported on the associated costs of women participants [52,53] but these were from two different reporting periods and had a wide variance in mean costs per concussion injury.…”

Background The extent of concussion injury in the rugby codes for women is unclear. Objective Our aim was to review all published studies reporting concussion injuries from match and training participation in rugby codes and report the pooled data estimates for rugby league and union concussion injury epidemiology. Methods We conducted a systematic literature analysis of concussion in rugby league and rugby union for published studies from January 1990 to July 2021. Data from 16 studies meeting the inclusion criteria were extracted for women’s concussion injuries and were subsequently pooled. Costs from Accident Compensation Corporation (ACC) data were attributed to the results to provide cost estimates. Results The pooled analysis match injury incidence of women’s concussion was higher for rugby league (10.3 per 1000 match hours) than rugby 15 s (2.8 per 1000 match hours) or rugby 7 s (8.9 per 1000 match hours). There was a fourfold difference in the pooled incidence of concussion in women’s rugby league (risk ratio [RR] 4.53, 95% confidence interval [CI] 1.8–11.3]; p = 0.0001) when compared with rugby 15 s. There was also a ninefold higher risk of a concussion during match participation compared with training participation for women’s rugby 15 s (RR 9.3, 95% CI 1.29–66.78; p = 0.0070). The total estimated costs for the concussions reported were NZ$1,235,101. For rugby 7 s, the pooled concussive injury burden was 33.2 days. Conclusions Our pooled analysis clarified the extent of concussion injury and the possible associated costs at several levels of the game for women’s rugby codes. The pooled mean days lost because of concussions was 33 days. As this was considerably longer than the 7- to 10-day expected timeframe outlined in the Concussion in Sport Consensus statement, these guidelines need to be updated to include sex-specific differences.

“…In Australasia, incidence rates range from 99.1 per 100 000 7 to 790 per 100 000 person years 6 . The Accident and Compensation Corporation recorded 97 955 claims for TBI over a 4‐year period costing NZ$1 450 643 667 11 with the lifetime cost of a single TBI in NZ estimated to be NZ$10 708 12 . Early recognition of TBI in the ED is called for in order to provide timely treatment.…”

Objective: There is limited research from Australasian EDs describing the demographic make-up, injury severity and impact of alcohol in patients requiring computed tomography (CT) for suspected traumatic brain injury (TBI). The present study aims to review the frequency and presenting patterns of patients who consume alcohol prior to presenting with suspected TBI. Methods: Retrospective observational study of patients referred for head CT to exclude TBI from a major referral centre and regional ED in New Zealand, between 1 September 2018 and 31 August 2019. Comparison groups were defined as 'alcohol involved' or 'no alcohol involved'. Results: 97/425 (22.8% [95% CI 18.3-27.4]) of included TBI presentations involved alcohol. 73/97 (75.3% [95% CI 58.6-93.5]) were male and 41/97 (42.3% [95% CI 29.3-55.2]) were aged 18-30 years. The alcohol group were more likely to report assault as the injury mechanism (19.6% [95% CI 10.8-28.4] vs 5.2% [95% CI 2.7-7.7], P < 0.05) and have Glasgow Coma Scale scores reflecting more moderate (13.5% [95% CI 5.9-21.1] vs 3.5% [95% CI 1.5-5.6]) and severe (5.6% [95% CI 0.7-10.5] vs 3.2% [95% CI 1.2-5.2] TBI.Presentation times post-injury were delayed compared to the no alcohol group (3.4 h [interquartile range 1.9-14.8] vs 2.8 h [interquartile range 1.8-6.6], P < 0.05). Conclusion:One quarter of patients with suspected TBI had consumed alcohol prior to their injury. Predominantly, those affected were young males who reported higher rates of assault; however, alcohol use was recorded in all age groups and sex. Alcohol-affected patients presented later, potentially delaying time to diagnosis. The present study supports the call for public health interventions that aim to reduce alcohol misuse.

“…Mild traumatic brain injuries (mTBIs) sustained during sport or physical activity represent an estimated 20–25% of all traumatic brain injuries [ 1 , 2 ]. mTBI is commonly described as an invisible injury because structural abnormalities are not detected post-mTBI using standard neuroimaging techniques [ 3 , 4 ].…”

Objectives To evaluate the clinical utility of tactile somatosensory assessments to assist clinicians in diagnosing sport-related mild traumatic brain injury (SR-mTBI), classifying recovery trajectory based on performance at initial clinical assessment, and determining if neurophysiological recovery coincided with clinical recovery. Research Design Prospective cohort study with normative controls. Methods At admission (n = 79) and discharge (n = 45/79), SR-mTBI patients completed the SCAT-5 symptom scale, along with the following three components from the Cortical Metrics Brain Gauge somatosensory assessment (BG-SA): temporal order judgement (TOJ), TOJ with confounding condition (TOJc), and duration discrimination (DUR). To assist SR-mTBI diagnosis on admission, BG-SA performance was used in logistic regression to discriminate cases belonging to the SR-mTBI sample or a healthy reference sample (pooled BG-SA data for healthy participants in previous studies). Decision trees evaluated how accurately BG-SA performance classified SR-mTBI recovery trajectories. Results BG-SA TOJ, TOJc, and DUR poorly discriminated between cases belonging to the SR-mTBI sample or a healthy reference sample (0.54–0.70 AUC, 47.46–64.71 PPV, 48.48–61.11 NPV). The BG-SA evaluated did not accurately classify SR-mTBI recovery trajectories (> 14-day resolution 48%, ≤14–day resolution 54%, lost to referral/follow-up 45%). Mann-Whitney U tests revealed differences in BG-SA TOJc performance between SR-mTBI participants and the healthy reference sample at initial clinical assessment and at clinical recovery (p < 0.05). Conclusions BG-SA TOJ, TOJc, and DUR appear to have limited clinical utility to assist clinicians with diagnosing SR-mTBI or predicting recovery trajectories under ecologically valid conditions. Neurophysiological abnormalities persisted beyond clinical recovery given abnormal BG-SA TOJc performance observed when SR-mTBI patients achieved clinical recovery.
