Background Mild traumatic brain injury (TBI) is associated with substantial costs due to over-triage of patients to computed tomography (CT) scanning, despite validated decision rules. Serum biomarker S100B has shown promise for safely omitting CT scans but the economic impact from clinical use has never been reported. In 2007, S100B was adapted into the existing Scandinavian management guidelines in Halmstad, Sweden, in an attempt to reduce CT scans and save costs. Methods Consecutive adult patients with mild TBI (GCS 14-15, loss of consciousness and/or amnesia), managed with the aid of S100B, were prospectively included in this study. Patients were followed up after 3 months with a standardized questionnaire. Theoretical and actual cost differences were calculated. Results Seven hundred twenty-six patients were included and 29 (4.7 %) showed traumatic abnormalities on CT. No further significant intracranial complications were discovered on follow-up. Two hundred twenty-nine patients (27 %) had normal S100B levels and 497 patients (73 %) showed elevated S100B levels. Over-triage occurred in 73 patients (32 %) and under-triage occurred in 39 patients (7 %). No significant intracranial complications were missed. The introduction of S100B could save 71 € per patient if guidelines were strictly followed. As compliance to the guidelines was not perfect, the actual cost saving was 39 € per patient. Conclusion Adding S100B to existing guidelines for mild TBI seems to reduce CT usage and costs, especially if guideline compliance could be increased.

Many studies have focused on the long-term impact of concussions in professional sports, but few have investigated short-term effects. This study examines concussion effects on individual players in the National Hockey League (NHL) by assessing career length, performance, and salary. Contracts, transactions, injury reports, and performance statistics from 2008–17 were obtained from the official NHL online publication. Players who sustained a concussion were compared with the 2008–17 non-concussed player pool. Career length was analyzed using Kaplan-Meier survival curves and stratification of player age, experience, and longevity. Player performance and salary changes were evaluated between the years before versus after concussion. Performance and salary changes were compared against non-concussed NHL athletes before/after their career midpoints. Of the 2194 eligible NHL players in the 9-year period, 309 sustained 399 concussions resulting in injury protocol. The probability of playing a full NHL season post-concussion was significantly decreased compared with the non-concussed pool (p < 0.05), specifically 65.0% versus 81.2% at 1 year into a player's career, 49.8% versus 67.4% at 2 years, and 14.6% versus 43.7% at 5 years. Performance was reduced at all non-goalie positions post-concussion (p < 0.05). Players scored 2.5 points/year less following a concussion. The total annualized financial impact from salary reductions after 1 concussion was $57.0 million, with a decrease of $292,000 per year in contract value per athlete. This retrospective study demonstrates that NHL concussions resulting in injury protocol activation lead to shorter career lengths, earnings reductions, and decreased performance when compared with non-concussed controls.

Examination of trends in Veterans Health Administration (VHA) healthcare utilization and costs among veterans with mild traumatic brain injury (mTBI) is needed to inform policy, resource allocation, and treatment planning. The objective of this study was to assess the patterns of VHA healthcare utilization and costs in the 3 years following TBI screening among veterans with mTBI, compared with veterans without TBI. A retrospective cohort study of veterans who underwent TBI screening in fiscal year 2010 was conducted. We used VHA healthcare utilization and associated costs by categories of care to compare veterans diagnosed with mTBI (n = 7318) with those who screened negative (n = 75,294) and those who screened positive but had TBI ruled out (n = 3324). Utilization and costs were greatest in year 1, dropped in year 2, and then leveled off. mTBI diagnosis was associated with high rates of utilization. Each year, healthcare costs for those with mTBI were two to three times higher than for those who screened negative, and 20–25% higher than for those who screened positive but had TBI ruled out. A significant proportion of healthcare use and costs for veterans with mTBI were associated with mental health service utilization. The relatively high rate of VHA utilization and costs associated with mTBI over time demonstrates the importance of long-term planning to meet these veterans' needs. Identifying and engaging patients with mTBI in effective mental health treatments should be considered a critical component of treatment planning.

•Repeat imaging has limited utility in low-risk, mild traumatic brain injury patients.•No patient with low-risk, mild traumatic brain injury had neurosurgical intervention.•Performing serial neurological examinations may be a safe, cost-effective alternative.•Transferring low-risk, mild traumatic brain injury patients may be unnecessary. Intracranial hemorrhage (ICH) is frequently found on computed tomography (CT) after mild traumatic brain injury (mTBI) prompting transfer to centers with neurosurgical coverage and repeat imaging to confirm hemorrhage stability. Studies suggest routine repeat imaging has little utility in patients with minimal ICH, no anticoagulant/antiplatelet use, and no neurological decline. Additionally, it is unclear which mTBI patients benefit from transfer for neurosurgery consultation. The authors sought to assess the clinical utility and cost effectiveness of routine repeat head CTs and transfer to tertiary centers in patients with low-risk, mTBI. Retrospective evaluation of patients receiving a neurosurgical consultation for TBI during a 4-year period was performed at a level 1 trauma center. Patients were stratified according to risk for neurosurgical intervention based on their initial clinical evaluation and head CT. Only patients with low-risk, mTBI were included. Of 531 patients, 119 met inclusion criteria. Eighty-eight (74.0 %) received two or more CTs. Direct cost of repeat imaging was $273,374. Thirty-seven (31.1 %) were transferred to our facility from hospitals without neurosurgical coverage, costing $61,384. No patient had neurosurgical intervention or mTBI-related in-hospital mortality despite enlarging ICH on repeat CT in three patients. Two patients had mTBI related 30-day readmission for seizure without ICH expansion. Routine repeat head CT or transfer of low-risk, mTBI patients to a tertiary center did not result in neurosurgical intervention. Serial neurological examinations may be a safe, cost-effective alternative to repeat imaging for select mTBI patients. A large prospective analysis is warranted for further evaluation.

Background/aim The risk of injury among Pee Wee (ages 11–12 years) ice hockey players in leagues that allow body checking is threefold greater than in leagues that do not allow body checking. We estimated the cost–effectiveness of a no body checking policy versus a policy that allows body checking in Pee Wee ice hockey. Methods Cost–effectiveness analysis alongside a prospective cohort study during the 2007–2008 season, including players in Quebec (n=1046), where policy did not allow body checking, and in Alberta (n=1108), where body checking was allowed. Injury incidence rates (injuries/1000 player-hours) and incidence proportions (injuries/100 players), adjusted for cluster using Poisson regression, allowed for standardised comparisons and meaningful translation to community stakeholders. Based on Alberta fee schedules, direct healthcare costs (physician visits, imaging, procedures) were adjusted for cluster using bootstrapping. We examined uncertainty in our estimates using cost–effectiveness planes. Results Associated with significantly higher injury rates, healthcare costs where policy allowed body checking were over 2.5 times higher than where policy disallowed body checking ($C473/1000 player-hours (95% CI $C358 to $C603) vs $C184/1000 player-hours (95% CI $C120 to $C257)). The difference in costs between provinces was $C289/1000 player-hours (95% CI $C153 to $C432). Projecting results onto Alberta Pee Wee players registered in the 2011–2012 season, an estimated 1273 injuries and $C213 280 in healthcare costs would be avoided during just one season with the policy change. Conclusion Our study suggests that a policy disallowing body checking in Pee Wee ice hockey is cost-saving (associated with fewer injuries and lower costs) compared to a policy allowing body checking. As we did not account for long-term outcomes, our results underestimate the economic impact of these injuries.

Abstract Objectives This paper provides an overview of the epidemiology of sport-related concussion and associated costs in New Zealand requiring medical treatment from 2001 to 2011 in seven sports codes. Design A retrospective review of injury entitlement claims by seven sports from 2001 to 2011. Methods Data were analyzed by sporting code, age, ethnicity, gender and year of competition for total and moderate-to-severe (MSC) Accident Compensation Corporation (ACC) claims and costs. Results A total of 20,902 claims costing $NZD 16,546,026 were recorded over the study period of which 1330 (6.4%) were MSC claims. The mean yearly number and costs of MSC claims were 133 ± 36 and $1,303,942 ± 378,949. Rugby union had the highest number of MSC claims per year (38; 95% CI 36–41 per 1000 MSC claims). New Zealand Māori recorded the highest total ($6,000,759) and mean cost ($21,120) per MSC claim. Conclusions Although MSC injury claims were only 6.4% of total claims, they accounted for 79.1% of total costs indicating that although the majority of sport-related concussions may be minor in severity, the related economic costs associated with more serious sport-related concussion can be high. The finding that rugby union recorded the most MSC claims in the current study was not unexpected. Of concern is that rugby league recorded a low number of MSC claims but the highest mean cost per claim. Due to the high mean cost per concussion, and the high total and mean cost for New Zealand Māori, further investigation is warranted.

Objectives:To describe patient and hospital characteristics associated with hospitalisation for a diagnosis of non-fatal sport-related concussion, and to determine factors associated with these hospitalisations.Methods:Children aged 5–18 years with a primary diagnosis of a sport-related concussion in the Nationwide Inpatient Sample (2000–2004) were identified. Length of stay and hospital charges for sport-related concussions were documented. Logistic regression was used to assess the association of patient or hospital characteristics with hospitalisations for sport-related concussion.Results:Between 2000 and 2004, a total of 755 non-fatal paediatric sport-related hospitalisations for concussion were identified. Nationwide, this represents 3712 hospitalisations and over US$29 million total hospital charges, with nearly US$6 million in total hospital charges per year. Over half (52.3%) of patients with concussion experienced loss of consciousness. Over 80% of the patients hospitalised for concussion received no procedures during their average 1.1 day (median 0.8 day) of hospital stay. Older age, but not gender, was associated with increased odds of sport-related hospitalisations for concussion. Non-teaching hospitals or hospitals in rural areas had significantly greater odds of admitting sport-related concussions versus other sport-related traumatic brain injuries compared with teaching or urban hospitals.Conclusions:Management of paediatric sport-related concussions varied, depending on the patient and the hospital. Better guidelines are needed for the identification and management of sport-related concussions. Standardised procedures for hospitals treating concussive injuries may also be warranted.
