Association Between Follow-Up Visit Timing After A Concussion and Subsequent Care Seeking in Children and Youth: A Population-Based Study in British Columbia.

To assess the relationship between follow-up visit timing and occurrence of the first subsequent health care seeking visit. The province of British Columbia, Canada. A total of 21029 children and youth who were diagnosed with an initial concussion from January 1, 2016, to December 31, 2017. These data were obtained from Population Data BC. A retrospective, descriptive correlational study. Follow-up timing was measured categorically as timely (4weeks), delayed (1-3months), or no follow-up; the occurrence of a subsequent health care visit beyond 3months postinjury was measured up to 12months at 3-month intervals (ie, 4-6, 7-9, and 10-12months). These variables were measured using diagnostic codes for concussion, post-concussion syndrome, and the 17 concussion symptoms. After controlling for sociodemographic characteristics, having a delayed follow-up, relative to timely follow-up, was associated with higher odds of a subsequent health care seeking visit at 4 to 6months (odds ratio [OR]=2.68; confidence interval [CI], 2.08-3.47), 7 to 9months (OR=1.71; CI, 1.21-2.40), and 10 to 12months (OR=1.67; CI, 1.13-2.48). In contrast to having a delayed follow-up, having no follow-up, relative to timely follow-up, was associated with not having a subsequent health care seeking visit at 4 to 6months (OR=0.57; CI, 0.48-0.67) and 7 to 9months (OR=0.79; CI, 0.66-0.96), respectively. Follow-up visit timing after a concussion in children and youth is associated with subsequent health care seeking. Greater efforts are needed to investigate the importance of initial follow-up visit timing, as they may play an integral role in injury prevention and symptom management following injury.

Concussion Characteristics in Adults With ADHD Seen in a Specialty Concussion Clinic.

Concussions are a prevalent health concern, affecting millions of individuals in the United States yearly. Concussion symptomology overlaps with other conditions making diagnosis and management particularly challenging, particularly among individuals with ADHD. ADHD is a neurodevelopmental disorder that affects a significant portion of the adult population. To enhance our understanding of symptom resolution and identify factors that could influence concussion care management, the purpose of the current study was to examine the recovery trajectory of adults diagnosed with both ADHD and concussion compared to the trajectory of adults who have experienced a concussion but do not have an ADHD diagnosis. The study included a retrospective chart review of patients treated for concussion at a concussion specialty clinic. The findings of the study revealed no significant differences in history of concussion or recovery time between patients with and without ADHD. It was observed that patients with ADHD had a higher prevalence of anxiety, depression, and other mental health conditions. The findings of the current study underscore the need for additional research to guide the care of patients diagnosed with both ADHD and concussion.

Concussion Assessment and Management Self-efficacy Among Irish Clinicians.

This study explored concussion assessment and management self-efficacy and practices of allied healthcare professionals in Ireland. (1) Self-efficacy levels and practices vary across different concussion assessment and management skills, (2) the ability to practice skills impacts self-efficacy most. Cross-sectional. Level 3. Survey of allied healthcare professionals (285 responders), investigating (1) demographics, (2) concussion assessment (immediate and office) and management (postconcussion advice and management/rehabilitation) self-efficacy levels and practices, and (3) factors affecting self-efficacy. Levels of self-efficacy among clinicians were 64.5 ± 26.6 (immediate assessment) and 56.6 ± 25.4 (postconcussion advice) (highest scores: concussion symptom checklist [80 ± 28.4], physical rest advice [80.1 ± 27.8]; lowest: Child Sport Concussion Assessment Tool [44.6 ± 41.2] and nutrition advice [34.1 ± 33.7]). Overall levels of self-efficacy among Certified Athletic Therapists and Chartered Physiotherapists were 51.5 ± 20.1 (assessment) and 62.1 ± 20.9 (management) (highest scores: history/clinical evaluation nonspecific to concussion [86.6 ± 16.2], physical rest advice [86.3 ± 20]; lowest: paper/pencil neuropsychological test [16.7 ± 28.6], advice on medication use [39.2 ± 35]). A strong positive correlation was observed between clinician self-efficacy and frequency of use of overall (r = 0.795; P < 0.01) and immediate (r = 0.728; P < 0.01) assessment, advice (r = 0.805; P < 0.01), and management (r = 0.812; P < 0.01) skills. Factors with greatest positive impact on clinician self-efficacy were the ability to practice skills during clinical placement (3.3 ± 0.9) and remaining emotionally (3.3 ± 0.8) and physically (3.3 ± 0.8) calm while practicing. Clinicians in Ireland had moderate self-efficacy in concussion care. Those who used concussion-relevant skills frequently in practice displayed higher self-efficacy for those skills. Concussion-related self-efficacy can be enhanced through practice in a clinical environment and through experiencing composure while practicing.

Concussion Care Seeking Among Active-Duty Military Service Members

Concussion Care Seeking Among Active-Duty Military Service Members

Is Access to Optimal Concussion Care for Pediatric Athletes Limited by Geography?

To evaluate access to optimal concussion care based on a pediatric patients' geography; the hypothesis is that differential access across the Unites States exists. Employed a novel strategy using internet searches to find local care, mimicking what families might do in different parts of the country. Virtual internet searches. Not applicable. Various metropolitan and rural geographic regions within each state in the United States. Evaluate access (defined as distance to clinic and ability to see pediatric patients) and optimal care (defined as self-referral process and presence of multidisciplinary care). Search strategy yielded 490 results. Overall ∼60% were within 50 miles of searched locations with significant differences in access based on rural versus metropolitan areas ( P < 0.0001); in rural areas, only ∼22% of results were within 50 miles. Only about one-third of the results (n = 157) saw pediatric patient with no differences between regions. There was significant regional and geographic variation for optimal care regarding both self-referral processes and access to multidisciplinary care. A diverse group of specialists was represented in search results for concussion care. Nationwide, there is an overall lack of access to multidisciplinary concussion care for pediatric patients. Additionally, those in rural communities face more limitations related to access to facilities with increased distances from closest clinic sites.

A - 15 Incorporating the Child Opportunity Index and Area Deprivation Index in Sport Concussion Research

Abstract Purpose Social determinants of health, including socioeconomic status (SES) and neighborhood characteristics, are underrepresented in concussion research. We examined two measures of neighborhood advantage and opportunity among patients accessing a multidisciplinary sports concussion clinic in Greater Boston. Method We collected the Child Opportunity Index (COI) and Area Deprivation Index (ADI) state decile scores and national percentile ranks for all new patients who presented to our clinic in 2023. The COI is an index of neighborhood conditions that may impact childhood development (e.g., education quality, SES, access to healthy food) with ratings from Very Low to Very High. The ADI characterizes an area’s socioeconomic conditions (e.g., income, housing quality, employment, education), with higher scores representing more disadvantage. Results There were 247 new patients who visited the clinic (Mage = 17.5, SDage = 5.2, 47.8% Girls/Women, 81.4% White, 4.0% Black, 6.5% Asian, 4.9% Hispanic). The majority lived in an area with a High or Very High state COI (74%) and High or Very High national COI (88%). The median ADI state decile was 2.00 (IQR = 1.00–4.00) and the median national percentile was 10.00 (IQR = 5.00–18.00) (representing the highest 10% of advantage). The state deciles for the two measures were correlated (Spearman rho = 0.64), but not redundant. Conclusions The COI and ADI are important, accessible measures of SES that can be included in future studies. Patients from low SES were greatly underrepresented in the clinic compared to the population of our metropolitan area. Patients were predominantly from higher SES, consistent with prior studies suggesting socioeconomic disparities accessing specialty concussion care.

Optimizing Concussion Care Seeking: Using Machine Learning to Predict Delayed Concussion Reporting.

Early medical attention after concussion may minimize symptom duration and burden; however, many concussions are undiagnosed or have a delay in diagnosis after injury. Many concussion symptoms (eg, headache, dizziness) are not visible, meaning that early identification is often contingent on individuals reporting their injury to medical staff. A fundamental understanding of the types and levels of factors that explain when concussions are reported can help identify promising directions for intervention. To identify individual and institutional factors that predict immediate (vs delayed) injury reporting. Case-control study; Level of evidence, 3. This study was a secondary analysis of data from the Concussion Assessment, Research and Education (CARE) Consortium study. The sample included 3213 collegiate athletes and military service academy cadets who were diagnosed with a concussion during the study period. Participants were from 27 civilian institutions and 3 military institutions in the United States. Machine learning techniques were used to build models predicting who would report an injury immediately after a concussive event (measured by an athletic trainer denoting the injury as being reported "immediately" or "at a delay"), including both individual athlete/cadet and institutional characteristics. In the sample as a whole, combining individual factors enabled prediction of reporting immediacy, with mean accuracies between 55.8% and 62.6%, depending on classifier type and sample subset; adding institutional factors improved reporting prediction accuracies by 1 to 6 percentage points. At the individual level, injury-related altered mental status and loss of consciousness were most predictive of immediate reporting, which may be the result of observable signs leading to the injury report being externally mediated. At the institutional level, important attributes included athletic department annual revenue and ratio of athletes to athletic trainers. Further study is needed on the pathways through which institutional decisions about resource allocation, including decisions about sports medicine staffing, may contribute to reporting immediacy. More broadly, the relatively low accuracy of the machine learning models tested suggests the importance of continued expansion in how reporting is understood and facilitated.

More Than Skin Deep: Patient-Provider Racial and Ethnic Concordance and Discordance in Collegiate Athletics and Concussion Management.

There is strong evidence that racial and ethnic disparities exist in multiple arenas of health and wellness. The causes of racial and ethnic differences in health care are multidimensional; one factor that may affect injury/illness communication, interactions, and outcomes is patient-provider racial and ethnic concordance. At present, it is unclear what role patient-provider racial and ethnic concordance and discordance plays in facilitating concussion care for collegiate athletes. To investigate the presence of athlete-athletic trainer (AT) racial and ethnic concordance and discordance among diagnosed concussion cases and examine if racial and ethnic concordance and discordance influences time (in days) until diagnosis, symptom resolution, or return-to-sport clinical milestones in collegiate athletes. Retrospective cohort study. Collegiate athletics. A total of 694 concussion cases (38.6% [n = 268] sustained by women, 61.4% [n = 426] sustained by men) that occurred within the 2015-2016 through 2019-2020 sport seasons at 9 institutions. The number of days from the date of injury to diagnosis, symptom resolution, and return to sport and from the date of diagnosis to symptom resolution and return to sport. Overall, 68.4% (n = 475) of concussion cases had patient-provider racial and ethnic concordance, and 31.6% (n = 219) were discordant. All concordant pairs included a White athlete and White AT. Time to diagnosis differed between the concordant and discordant groups (median [interquartile range] = 1 [0-2] versus 0 [0-1], respectively) only in the model adjusted for sex, sport type, and availability of an AT (odds ratio [95% CI] = 1.46 [1.07-1.85]). There were no other group differences. One-third of concussion cases had athlete-AT racial and ethnic discordance. Although this group was diagnosed with a concussion 1 day sooner than the concordant group, no differences were observed for any concussion recovery milestones. These findings suggest that patient-provider racial and ethnic concordance may play a minor role in concussion recognition or reporting but not necessarily in the management and recovery thereafter.

Measurement Properties of the Activities-Specific Balance Confidence Scale in Adults From the General Population With Concussion: A Report From the Toronto Concussion Study

ObjectiveThe aim of this study was to establish the internal consistency and construct validity of the Activities-specific Balance Confidence (ABC) Scale and ABC-6 in adults from the general population with concussion. DesignProspective analysis. SettingOutpatient concussion care clinic. ParticipantsAdults from the general population with concussion referred to a concussion care clinic within 7 days of injury (N=511). InterventionsNot applicable. Main Outcome MeasuresBalance confidence was assessed with the Activities-specific Balance Confidence (ABC) Scale and the ABC-6. Concussion symptoms were characterized using the Sport Concussion Assessment Tool version 5 (SCAT5) symptom checklist. Instrumented measures of balance and gait included center of pressure velocity and double support time, respectively. Balance was also assessed using the mBESS. ResultsThe ABC and ABC-6 were strongly correlated (ρ=0.980, P<.001). Cronbach α for ABC and ABC-6 was 0.966 and 0.940, respectively. Factor analysis verified the existence of 2 components of the ABC, 1 including all items of the ABC-6 as well as 3 additional items. ABC and ABC-6 were moderately significantly correlated with SCAT5 symptom number, severity, and symptom domain (ρ=−0.350 to −0.604). However, correlations between ABC and ABC-6 with instrumented measures of balance and gait were not statistically significant, except for double support time during dual-task gait with ABC-6 (ρ=−0.218). ConclusionsIn community-dwelling adults with concussion, the ABC and ABC-6 have good internal consistency. Convergent validity is stronger for symptom endorsement measures within SCAT5 domains, which has a similar construct (subjectivity) to balance confidence. Both the ABC and ABC-6 are valid measures of balance self-efficacy in adults from the general population with concussion. The ABC-6 may be a useful tool for characterizing the effect of concussion on perceptions of the ability to perform functional tasks that challenge balance and mobility.

Framing racial disparities within sports related concussion (SRC): an ecological framework for understanding biases and disparities in concussion care for black athletes

Privilege and marginalization associated with racial background have been posited as contributors to why Black athletes face disparities within their care, treatment, and recovery from sport-related concussion (SRC). However, empirical findings have limited exploration on how disparate outcomes have emerged, and the interaction with systems of biases, power and disenfranchisement. To understand concussion care disparities, a qualitative content analysis was conducted in three phases: [I] identifying salient literature on racial differences for Black athletes with SRC (N = 29), [II] qualitative analysis of literature to determine salient topics, themes and patterns within the literature, and [III] constructing a novel ecological-systems framework that encapsulates the ‘why’ and ‘how’ related to psychosocial and sociocultural experiences of power, access, and biases for Black athletes. The content analysis yielded two patterns, where concussion care decisions are influenced by (1) biased, unconscious beliefs that posit Black athletes as uniquely invincible to injury and pain, and (2) inadequate access to concussion knowledge and resources, which both moderate SRC injury risk, diagnosis, recovery and outcomes. Ultimately, our novel framework provides a clear thread on how historical, macro-level policy and perceptions can impact micro-level clinical care and decision-making for Black athletes with SRC.

Association between days for concussion recovery and initial specialty clinic evaluation within 48 hours

BackgroundResearchers have highlighted the importance of early access to concussion care within one week of injury in reducing recovery times. However, a persisting question for concussion researchers is “just how early is important?” The purpose of this study was to examine differences in recovery time as predicted by the number of days elapsed since injury (DSI) to initial evaluation among patients who had access to a specialty concussion clinic within seven days. We hypothesized that DSI group membership, even within seven days, would significantly predict risk of protracted recovery (i.e., beyond 21 days).MethodsIn this archival study, retrospective data were gathered from electronic medical records between September 2020 to March 2022. Records of participants between ages 12–18, those diagnosed with a sports-related concussion based on initial clinic visit diagnosis by a medical provider and those who established care within seven days of injury at a large pediatric specialty concussion clinic were examined. Participants were divided into three DSI groups (patients seen in < 48 h: “acute”, patients seen between 49 h < and < 96 h: “sub-acute”, and patients seen between 97 < and < 168 h: “post-acute”). A general linear model was constructed to examine relationships between relevant concussion factors (e.g., Post Concussion Scale Score, neurodevelopmental history, psychiatric history, concussion history, migraine history, overall VOMS change score, cognitive testing, sex, age, race, and ethnicity) that were either significant in the preliminary analysis or in clinical judgement and recovery time. Adjusted odds ratios (OR) were derived from a binary logistic regression model, in which recovery time was normal (≤ 21 recovery days) or protracted (> 21 recovery days).ResultsA total of 856 participants were eligible. Adolescents in the acute group (M = 15.12, SD = 8.04) had shorter recovery times in days compared to those in the sub-acute (M = 17.98, SD = 10.18) and post-acute (M = 21.12, SD = 10.12; F = 26.00, p < .001) groups. Further, participants in the acute (OR = 4.16) and sub-acute (OR = 1.37) groups who accessed specialty concussion clinics within 48 h were 4 times more likely to have a normal recovery and recovered approximately 6 days faster than the post-acute care group.ConclusionsEarlier concussion care access predicted recovery times and was associated with lower risk for protracted recovery.

Resident perceptions of learning challenges in concussion care education

Background: Resident-focused curricula that support competency acquisition in concussion care are currently lacking. We sought to fill this gap by developing and evaluating Spiral Integrated Curricula (SIC) using the cognitive constructivism paradigm and the Utilization-Focused Evaluation (UFE) framework. The evidence-based curricula consisted of academic half-days (AHDs) and clinics for first- and second-year family medicine residents. Our first pilot evaluation had quantitatively demonstrated effectiveness and acceptability but identified ongoing challenges. Here we aimed to better describe how concussion learning is experienced from the learners’ perspective to understand why learning challenges occurred. Methods: A qualitative interpretative cohort study was utilized to explore resident perceptions of concussion learning challenges. Participants completed six monthly longitudinal case logs to reflect on their concussion experience. Semi-structured interviews were conducted. Results: Residents' beliefs and perceptions of their roles influenced their learning organization and approaches. Challenges were related to knowledge gaps in both declarative knowledge and knowledge interconnections. Through reflection, residents identified their concussion competency acquisition gaps, leading to transformative learning. Conclusion: This Spiral Integrated Design created vigorous processes to interrogate “concussion” competency gaps. We discussed resident mindsets and factors that hindered “concussion” learning and potentially unintentional negative impacts on the continuity of patient care. Future studies could explore how to leverage humanistic adaptive expertise, cross-disciplines for curriculum development, and evaluation to overcome the hidden curriculum and to promote integrated education and patient care.

Optimizing Concussion Care Seeking: Connecting Care-Seeking Behaviors and Neurophysiological States Through Blood Biomarkers

Background: Timely and appropriate medical care after concussion presents a difficult public health problem. Concussion identification and treatment rely heavily on self-report, but more than half of concussions go unreported or are reported after a delay. If incomplete self-report increases exposure to harm, blood biomarkers may objectively indicate this neurobiological dysfunction. Purpose/Hypothesis: The purpose of this study was to compare postconcussion biomarker levels between individuals with different previous concussion diagnosis statuses and care-seeking statuses. It was hypothesized that individuals with undiagnosed concussions and poorer care seeking would show altered biomarker profiles. Study Design: Cohort study; Level of evidence, 3. Methods: Blood samples were collected from 287 military academy cadets and collegiate athletes diagnosed with concussion in the Advanced Research Core of the Concussion Assessment, Research and Education Consortium. The authors extracted each participant’s self-reported previous concussion diagnosis status (no history, all diagnosed, ≥1 undiagnosed) and whether they had delayed or immediate symptom onset, symptom reporting, and removal from activity after the incident concussion. The authors compared the following blood biomarkers associated with neural injury between previous concussion diagnosis status groups and care-seeking groups: glial fibrillary acidic protein, ubiquitin c-terminal hydrolase-L1 (UCH-L1), neurofilament light chain (NF-L), and tau protein, captured at baseline, 24 to 48 hours, asymptomatic, and 7 days after unrestricted return to activity using tests of parallel profiles. Results: The undiagnosed previous concussion group (n = 21) had higher levels of NF-L at 24- to 48-hour and asymptomatic time points relative to all diagnosed (n = 72) or no previous concussion (n = 194) groups. For those with delayed removal from activity (n = 127), UCH-L1 was lower at 7 days after return to activity than that for athletes immediately removed from activity (n = 131). No other biomarker differences were observed. Conclusion: Individuals with previous undiagnosed concussions or delayed removal from activity showed some different biomarker levels after concussion and after clinical recovery, despite a lack of baseline differences. This may indicate that poorer care seeking can create neurobiological differences in the concussed brain.

Concussion Care in Teenage Athletes.

Concussion is a form of traumatic brain injury that occurs commonly in pediatric patients. One group at higher risk for concussion is adolescent and teenage athletes. Athletes may sustain one or more concussions throughout their athletic careers, and these injuries may lead to significant morbidities for children. Although most concussion symptoms will resolve in less than 1 month, there is a subset of patients for whom symptoms may persist. Given the increased interest in preventing long-term sequelae related to concussion, legislation has been passed across the United States that aims to identify concussion promptly and remove participants from play after an injury has occurred. Care and treatment for concussion is evolving, with newer recommendations stating that complete or extreme rest may be unnecessary during the recovery period. Pediatricians and those who interact with young athletes should be aware of the guidelines surrounding return-to-play and return-to-learn in their geographic area of practice. [Pediatr Ann. 2024;53(2):e39-e41.].

CONNECTing Concussion Care with Research Across Ontario.

Common data elements (CDEs) for concussion, as established by international bodies, are not being widely used in Ontario, resulting in significant variability in the data being assessed and collected across clinics. CDEs support standardization of care as well as large-scale data sharing for high impact research. A collaborative network - Concussion Ontario Network: Neuroinformatics to Enhance Clinical care and Translation (CONNECT) - comprised of health care professionals, researchers, members from advocacy groups, and patients was formed to establish and implement CDEs for concussion care and research. While the seeds have been planted and initial effectiveness demonstrated, future challenges exist.

Concussion-Related Decision-Making by Certified Athletic Trainers: Implications for Concussion Prevention and Care.

Concussions are a common sport-related injury that require appropriate initial care. Athletic trainers, often a primary source of healthcare for student-athletes, are key individuals involved in initial concussion diagnostic and management decisions. Challenges exist within the athletic environment that may hinder the consistency, efficacy, and/or effectiveness of concussion-related decision-making by athletic trainers, thereby impacting secondary concussion prevention and patient health. The purpose of this study was to identify factors that impact the intentions of athletic trainers to make appropriate concussion-related decisions under various circumstances. Overall, 1029 participants completed a survey examining educational precursors (quantity and quality of healthcare communication educational focus), demographic precursors (age, gender, educational degree, and employment setting), theory-based mediators (attitudes, perceived norms, and personal agency), and external mediators (knowledge, salience, and communication/collaboration practices) on appropriate concussion-related decision-making intentions. Data were analyzed using a two-step structural equation modeling approach. Quality of healthcare communication educational focus indirectly impacted appropriate concussion-related decision-making intentions via perceived behavioral control and communication/collaboration practices. Additionally, several factors impacted intentions to make appropriate concussion-related decisions directly including employment setting, self-efficacy, and general attitudes towards decision-making and concussions. Concussion prevention is aided by the initial and appropriate action taken by a healthcare professional to reduce immediate consequences; however, this action may be influenced by stakeholder relationships. These influential factors of decision-making may place athletes at further injury risk and negatively impact overall athlete health. As such, a sound theoretical framework incorporating the complexity of factors that may influence decision-making is needed.

Effectiveness of treatment for concussion-related convergence insufficiency: The CONCUSS study protocol for a randomized clinical trial.

To describe CONCUSS, a randomized clinical trial (RCT) designed to compare the following: the effectiveness of immediate office-based vergence/accommodative therapy with movement (OBVAM) to delayed OBVAM as treatments for concussion-related convergence insufficiency (CONC-CI) to understand the impact of time (watchful waiting), the effect of OBVAM dosage (12 versus 16 therapy sessions), and to investigate the underlying neuro-mechanisms of OBVAM on CONC-CI participants. CONCUSS is an RCT indexed on https://clinicaltrials.gov/study/NCT05262361 enrolling 100 participants aged 11-25 years with medically diagnosed concussion, persistent post-concussive symptoms 4-24 weeks post-injury, and symptomatic convergence insufficiency. Participants will receive standard concussion care and will be randomized to either immediate OBVAM or delayed (by six weeks) OBVAM. At the Outcome 1 examination (week 7), clinical assessments of success as determined by changes in the near point of convergence (NPC), positive fusional vergence (PFV), and symptoms will be compared between the two treatment groups. After the Outcome 1 visit, those in the delayed group receive 16 visits of OBVAM, while those in the immediate OBVAM group receive four more therapy visits. Outcome 2 assessment will be used to compare both groups after participants receive 16 sessions of OBVAM. The primary measure is the between-group differences of the composite change in the NPC and PFV at the Outcome 1 visit. Secondary outcome measures include individual clinical measures, objective eye-tracking parameters, and functional brain imaging. Major features of the study design include formal definitions of conditions and outcomes, standardized diagnostic and treatment protocols, a delayed treatment arm, masked outcome examinations, and the incorporation of objective eye movement recording and brain imaging as outcome measures. CONCUSS will establish best practices in the clinical care of CONC-CI. The objective eye movement and brain imaging, correlated with the clinical signs and symptoms, will determine the neuro-mechanisms of OBVAM on CONC-CI.

Factors Influencing Length of Care in Physical Therapy After Pediatric and Adolescent Concussion.

Social determinants of health including insurance type, income, race, and ethnicity have been shown to influence the utilization of physical therapy and recovery after an orthopedic injury. The influence of social determinants of health on the utilization of physical therapy and recovery from concussion is not well understood. Prospective observational registry study in a specialty concussion program. Patients diagnosed with a concussion using the Postconcussion Symptom Inventory and the visio-vestibular examination (VVE) who were also referred to physical therapy were included. The main outcomes of interest were the number of days from referral to initial physical therapy evaluation and the number of physical therapy visits completed. Information related to patients' age, race, ethnicity, sex, insurance type, and Child Opportunity Index was extracted from the registry. Multivariate and univariate regressions were used to assess the associations of each sociodemographic characteristic with the outcomes. A total of 341 patients diagnosed with concussion between January 2017 and December 2023 met inclusion criteria. The average age was 14.77, and 64% were female. Patients' age, race, ethnicity, insurance type, and Child Opportunity Index were not associated with days to evaluation or length of care in physical therapy. Higher PCSI scores in children under 12years (coefficient: 0.17, 95% CI,0.06-0.29) and female sex (coefficient: 1.2, 95% CI, 0.26-2.1) were associated with a longer course of care in physical therapy. Patients with an abnormal VVE score had on average 2.1 more physical therapy visits than those with a normal VVE score (coefficient: 2.1, 95% CI, 0.73-3.5). Higher PCSI scores in children, female sex, and higher VVE scores in general predicted a longer course of care in physical therapy. Implementation of a clinical care pathway for concussion care using the PCSI and the VVE may be one strategy to help mitigate systemic factors that might otherwise negatively influence access to physical therapy.

Evaluating the Association Between Sociodemographic and Health Variables With Baseline Concussion Testing in Young Athletes

Background: Baseline concussion testing can be helpful to perform when providing concussion care for young athletes. To appropriately interpret these data, it is important to understand how certain factors may affect concussion testing. Purpose: To examine the relationship of sociodemographic and health variables with baseline concussion testing in young athletes. Study Design: Cross-sectional study; Level of evidence, 3. Methods: High school and middle school athletes competing in sports or positions at high risk for concussion (football, soccer, ice hockey, wrestling, lacrosse, and pitchers/catchers in baseball/softball) during the 2020-2021 or 2021-2022 academic years completed annual baseline concussion testing and were included in the study. Baseline data included self-reported demographic and medical information, a graded symptom checklist, the Standardized Assessment of Concussion, and the King-Devick test. A validated measure, HOUSES (HOUsing-based index of SocioEconomic Status), was used to determine participants’ socioeconomic status (SES) by linking personal address information to publicly available property data. Multivariable linear regression models were fit to analyze the relationship of concussion baseline testing to sociodemographic and health variables. Results: Among the eligible 2747 athletes (mean age, 15.4 ± 1.5 years; 73.6% male), the mean Standardized Assessment of Concussion score was 26.7 ± 2.0 and the mean best King-Devick test time was 50.3 ± 10.1 seconds. Higher baseline symptom severity scores were related to lower SES ( P = .002). A lower (ie, poorer) mean Standardized Assessment of Concussion score was significantly associated with the following in the multivariable model: male sex ( P &lt; .001), younger age ( P &lt; .001), Black/African American race ( P = .029), Hispanic ethnicity ( P = .016), previous diagnosis of learning disorder or attention-deficit hyperactivity disorder ( P &lt; .001), and lower SES ( P = .003). A higher (ie, poorer) mean King-Devick test time was related to younger age, previous diagnosis of a learning disorder or attention-deficit hyperactivity disorder, and lower SES (all P &lt; .001). Conclusion: Baseline concussion testing was found to be associated with certain sociodemographic variables and underlying health conditions in high school and middle school athletes.

70 Neuropsychological Consulting in Concussion Management: Remote Models Increase Access to Care

Objective:Neuropsychological assessment is the cornerstone of concussion management, and the nature of its delivery can vary widely. While literature concerning post-concussion care typically revolves around in-person evaluation, the proliferation of computerized neuropsychological tests (CNTs) has allowed for some distance between concussion patients and the neuropsychologist. In the wake of a global pandemic, several papers describing the use of telehealth for concussion care have emerged; however, the small samples found in these studies may suggest that access to care remains an issue. Additionally, telehealth may not be a sustainable fee-for-service approach as CMS aims to curtail telehealth reimbursement for behavioral health clinicians. The objective of the present study is to describe a remote neuropsychological consultation model of concussion management and evaluate its productivity and impact in a rural setting.Participants and Methods:In this model, a neuropsychologist based at an academic medical center in the northeastern United States consulted to middle school, high school, and collegiate concussion management programs. Students typically were administered baseline ImPACT tests prior to participation in sports, and all students in the current sample completed post-injury ImPACT tests as part of return to play protocols. The neuropsychologist read test results through the test’s online portal, then communicated interpretation and recommendations via email or phone to the school’s representative (e.g., athletic trainer, athletic director, or school nurse). 837 unique concussions were recorded between 2019 and 2022. After removing abnormal cases (e.g., COVID-19 school closures, extended college breaks, non-concussions, and non-return to play decisions), 790 unique concussions (51.4% male) were included for analysis, with a mean age of 16.84 years (SD=2.17). Descriptive statistics were used to characterize the sample.Results:Across 790 unique concussions, 7 were middle school, 571 were high school, and 212 were college students. 1,750 total postinjury ImPACT tests were administered over the three-year period. Per concussion, an average of 2.22 (SD=0.90) tests were used. Average time to the last ImPACT given was 18.47 days (SD=16.59), with a median of 15 days. Ten concussions (1.27% of total concussions) occurred within 3 months of a previous injury. The distance between schools and the medical center ranged from 2.4 to 102 miles (M=60.29; SD=34.34).Conclusions:The current study suggests that there is value in a remote model of neuropsychological consultation for concussion management. While telehealth offers a promising method of evaluation for concussion, it may be inaccessible and present reimbursement challenges. The remote consultation model described here increases access to care by eliminating in-person visits, which decreases demand for physical space at medical centers and increases access to rural populations with seemingly no negative effect on care. This consultation model also allows neuropsychologists working in concussion management more flexibility, potentially increasing the volume of cases they can assess. This program evaluation suggests remote models have merit, but replication studies in different regions of the country are needed.
