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.

Objective:
Rapid automatized naming (RAN) assesses pre-literacy and could be useful for assessing the effects of HIV infection on the development of literacy. Many children with HIV live in sub-Saharan Africa, but the RAN has not been well-studied there. Cultural differences in when children learn color names and in how they prioritize between accuracy and speed can affect RAN results. Typically, RAN and other cognitive functions (e.g., general intelligence, processing speed, working memory, attention) are strongly related. Our goal is to examine how RAN performance relates to neurocognitive function in sub-Saharan Africa and whether RAN performance could reveal the effect of HIV on pre-literacy. The current study examines the relationship between RAN performance and cognitive variables in both children living with HIV (CLWH) and healthy controls in Tanzania.
Participants and Methods:486 children (ages 3-8) were administered RAN Color and Object tasks as part of a larger longitudinal study in Dar es Salaam, Tanzania. All participants were also administered the Leiter International Performance Scale - 3rd Edition (Leiter-3), a test of nonverbal intelligence and general cognitive function. Binomial logistic regression examined the likelihood of completing a RAN task and included age, Leiter-3 composite standard scores, and HIV status. Multiple linear regression using the same predictors assessed factors associated with RAN completion time in children who completed the tests. SES and education were not included in the model specifications because they were not correlated with any RAN measures.
Results:Only 40% of children could complete the RAN Color task, while 88% completed the Object task. Logistic regression models showed that age (p<0.001), Leiter-3 Nonverbal IQ (p<0.01), and Processing Speed (p<0.001) composite scores were all unique predictors of whether children would complete the RAN Color task. Age (p <0.001) and Nonverbal IQ (p<0.001) were predictors of completing of the RAN Object task. Of those who could complete the RAN Color task, multiple linear regression demonstrated that age (p<0.01), Leiter-3 Nonverbal IQ (p=0.01) and Processing Speed (p=0.001) composites predicted completion time, with the model accounting for 25% of the variance. For the RAN Object task, multiple linear regression indicated age (p<0.001), Leiter-3 Processing Speed (p=0.01) and Nonverbal Memory (p=0.01) composites, and living with HIV (p=0.01), predicted completion time, with the model accounting for 42% of the variance.
Conclusions:Completion rates for RAN Color and Object tasks were low but improved with age. Consistent with brain maturation, increasing age and processing speed improved completion time, regardless of the RAN task. General cognitive ability predicted RAN Color performance, and Nonverbal Memory (encompassing attention, working memory, and retrieval) and HIV status additionally predicted RAN Object performance. Results extend research indicating RAN is distinct yet multifactorial, relying on various neurocognitive functions working together. Additionally, the relationship of HIV to RAN Object performance implies an overlap between the neurocognitive functions inherent in RAN and the neurocognitive weaknesses often reported in CLWH. These findings suggest cognitive vulnerabilities in CLWH may extend to literacy skills in sub-Saharan Africa, which requires further study.

Objective:
When neuropsychologists serve as consultants to schools, concussion management programs are associated with fewer referrals, faster cognitive recovery, and reduced incidence of protracted recovery compared to programs with physician consultants. However, accessing neuropsychological services can be challenging due to geographical and financial barriers. Particularly in rural areas, travel associated with post-concussion management can represent as a significant financial and time burden. Increasing accessibility to neuropsychologists has the potential to address these concerns, while also providing quality care to more
individuals. The current study aims to assess the cost-effectiveness and clinical outcomes of a remote, neuropsychologist-led consultation model of concussion management. We hypothesized that this remote model would save patients both money and time, while also improving patient outcomes.
Participants and Methods:604 high school concussion cases occurring between May 2019 and May 2022 were reviewed; 571 were included in the current analysis. The sample was 51% male with a mean age of 15.8 years (SD=1.32). All students took ImPACT tests following suspected concussions, with tests administered at the school by certified athletic trainers or nurses. Test results were electronically reviewed by the consulting neuropsychologist. Interpretations and recommendations were then sent via email to the school official. Cognitive recovery, defined as the days from the injury to the final ImPACT test, and incidence of repeat concussions, or concussions occurring within 3 months of a previous concussion, were used as indicators of patient outcomes. Financial burden was determined by calculating the round-trip distance in miles from the patient’s school to the neuropsychologist’s medical center, then multiplying this number by the 2022 standard mileage reimbursement rate of $0.63/mile to determine the travel cost for a single consultation.
Results:The sample consisted of 571 individual concussion cases and 1,285 total ImPACT tests. An average of 2.25 tests were administered for each concussion case (SD=0.90), with an average of 18.47 days to the final test (SD=16.59). 8 concussions (1.4% of total concussions) occurred within 3 months of a previous injury. The distance from schools to the closest available neuropsychologist ranged from 2.4 to 102 miles. The remote nature of the consultation model allowed for patients to avoid up to 204 miles, or up to 4.5 hours, of driving for each consultation. Thus, patients saved anywhere from $3.00 to $127.50 in travel costs per consultation.
Conclusions:The remote nature of this consultation model yielded a similar cognitive recovery time to previous literature, indicating that it may be as effective as in-person consultation. Repeat concussions represented less than 1.5% of concussion cases, indicating that care was successful enough to prevent second concussions in the majority of the sample. The remote nature of the model also saved patients time (up to 4.5 hours of driving) and money (up to $127.50 in travel costs). Thus, a remote consultation model has the potential to increase access to first-rate concussion care in rural settings, while also being cost- and time-effective for patients.
