Addition of Occupational Therapy to an Interdisciplinary Concussion Clinic Improves Identification of Functional Impairments

Role of Occupational Therapy Cognitive Assessment in Mild Traumatic Brain Injury: Is Universal Consultation Required?

INTRODUCTION

Mild traumatic brain injury (mTBI) or concussion is prevalent among trauma patients, but symptoms vary. Assessing discharge safety is not standardized. At our institution, occupational therapy (OT) performs cognitive assessments for mTBI to determine discharge readiness, potentially increasing resource utilization. We aimed to describe characteristics and outcomes in mTBI trauma patients and hypothesized that OT consultation was associated with increased length of stay (LOS).

METHODS

This is a retrospective study at a level 1 trauma center over 17 mo. All patients with mTBI, without significant concomitant injuries, were included. We collected data regarding OT assessment, LOS, mechanism of injury, Glasgow coma score, injury severity score (ISS), concussion symptoms, and patient disposition. Statistical analysis was performed, and significance was determined when P < 0.05.

RESULTS

Two hundred thirty three patients were included. Median LOS was 1 d and ISS 5. Ninety percent were discharged home. The most common presenting symptom was loss of consciousness (85%). No symptoms were associated with differences in LOS or discharge disposition (P > 0.05). OT consult (n = 114, 49%) was associated with longer LOS and higher ISS (P < 0.01). Representation with concussive symptoms, discharge disposition, mechanism of injury, and patient demographics were no different regardless of OT consultation (P > 0.05).

CONCLUSIONS

mTBI is common and assessment for discharge safety is not standardized. OT cognitive assessment was associated with longer LOS and higher injury severity. Despite institutional culture, OT consultation was variable and not associated with improved concussion-related outcomes. Our data suggest that OT is not required for mTBI discharge readiness assessment. To improve resource utilization, more selective OT consultation should be considered. Further prospective data are needed to identify which patients would most benefit.

Advances in Neurorehabilitation: Strategies and Outcomes for Traumatic Brain Injury Recovery

Traumatic brain injury (TBI) consists of an external physical force that causes brain function impairment or pathology and globally affects 50 million people each year, with a cost of 400 billion US dollars. Clinical presentation of TBI can occur in many forms, and patients usually require prolonged hospital care and lifelong rehabilitation, which leads to an impact on the quality of life. For this narrative review, no particular method was used to extract data. With the aid of health descriptors and Medical Subject Heading (MeSH) terms, a search was thoroughly conducted in databases such as PubMed and Google Scholar. After the application of exclusion and inclusion criteria, a total of 146 articles were effectively used for this review. Results indicate that rehabilitation after TBI happens through neuroplasticity, which combines neural regeneration and functional reorganization. The role of technology, including artificial intelligence, virtual reality, robotics, computer interface, and neuromodulation, is to impact rehabilitation and life quality improvement significantly. Pharmacological intervention, however, did not result in any benefit when compared to standard care and still needs further research. It is possible to conclude that, given the high and diverse degree of disability associated with TBI, rehabilitation interventions should be precocious and tailored according to the individual's needs in order to achieve the best possible results. An interdisciplinary patient-centered care health team and well-oriented family members should be involved in every stage. Lastly, strategies must be adequate, well-planned, and communicated to patients and caregivers to attain higher functional outcomes.

Surveying the Landscape of Persistent Concussive Symptoms in Adults Through an Occupational Lens

IMPORTANCE

Little is known about how and to what extent persistent concussive symptoms affect occupational performance in adults.

OBJECTIVE

To evaluate the impact of persistent postconcussive symptoms on occupational performance.

DESIGN

A cross-sectional study design was used in which the occupational performance needs of adults with persistent concussion symptoms were identified by a trained occupational therapist via semistructured interview.

SETTING

University research space.

PARTICIPANTS

Adults ages 18 to 60 yr experiencing persistent concussion symptoms.

OUTCOMES AND MEASURES

Occupational performance was evaluated using the Canadian Occupational Performance Measure. Data were then categorized by two researchers using the Occupational Therapy Practice Framework: Domain and Process (4th ed.).

RESULTS

The most commonly affected occupational performance areas included education and work, social participation, and performance of instrumental activities of daily living.

CONCLUSIONS AND RELEVANCE

Aligning with prior knowledge of the impact of psychosocial difficulties and higher order cognitive deficits on daily life, performance of complex occupations is heavily affected in adults with persistent concussive symptoms. Plain-Language Summary: The functional impact of symptoms that adults experience postconcussion becomes apparent as they return to their life occupations. The results of this study showed that adults with persistent concussive symptoms more commonly experienced occupational challenges with participation in education, social activities, and the performance of instrumental activities of daily living, with subtle, important variations in symptoms across adults. Detailed, client-centered evaluation of occupational performance changes postconcussion is an area of potential growth for occupational therapy practice and research.

Unmet Need for Outpatient Occupational Therapy Services Among Veterans With Mild Traumatic Brain Injury in the Veterans Health Administration: The Role of Facility Characteristics

OBJECTIVE

To investigate whether participation restrictions, an indicator of need for occupational therapy (OT), was associated with outpatient OT utilization in the Veterans Health Administration (VHA) among Veterans with mild traumatic brain injury (mTBI), and whether this relation differs by facility characteristics.

DESIGN

In a secondary analysis of national VHA data, we used modified Poisson regression to model OT utilization (yes/no) as a function of participation restrictions (Mayo-Portland Adaptability Inventory Participation Index [M2PI]), facility characteristics, and covariates. Facility characteristics included complexity, geographic region, and self-reported access to specialty care. Covariates included prior OT utilization, sociodemographic factors, injury characteristics, and spatial access (eg, drive time). Interactions estimated whether the relation between participation restrictions and OT utilization differed across facility characteristics.

SETTING

Outpatient setting in the VHA.

PARTICIPANTS

8684 Veterans with a clinician-confirmed mTBI who received outpatient VHA care between 2012 and 2020 (N=8684).

INTERVENTIONS

None.

MAIN OUTCOME MEASURE(S)

OT utilization was measured within a year of M2PI administration using VHA administrative data.

RESULTS

Many Veterans who did not receive OT reported participation limitations, indicating unmet need for OT (eg, 67% with leisure restrictions). Participation restrictions were associated with increased likelihood of receiving OT (risk ratio [RR]=1.01; 95% confidence interval [CI]=1.006-1.019), suggesting a tendency for Veterans' OT-related needs to be satisfied. However, interactions indicated that this was not the case among Veterans receiving care in lower complexity facilities, and those in the South. Veterans with longer drive times were less likely to receive OT (RR=0.82; 95% CI=0.744-0.904).

CONCLUSIONS

Participation restrictions were associated with OT utilization, yet many Veterans with mTBI who may have benefited did not receive such care. Specific barriers to accessing OT (eg, OT practitioner supply) should be investigated. Novel care models can ensure access to OT services among Veterans seeking care at less-resourced and/or geographically distant VHA facilities.

Examining the interdisciplinary approach for treatment of persistent post-concussion symptoms in adults: a systematic review

BACKGROUND

The objective of this review is to examine the evidence for the interdisciplinary approach in treatment of persistent post-concussion symptoms in adults.

METHODS

This systematic literature search was undertaken according to the Preferred Reporting Items for Systematic and Meta-Analysis (PRISMA) guidelines. Five electronic databases were searched: CINAHL, Informit, ProQuest, PubMed and Scopus. After screening and quality assessment, the review included six studies published in English and peer-reviewed journals, between 2011 and 2021 to return contemporary evidence.

RESULTS

The results revealed that there was significant variation between measures used and the timing of the pre- and post-treatment assessment. The studies found an interdisciplinary approach to be beneficial, however, the challenges of inherent heterogeneity, lack of clarity for definitions and diagnosis, and mixed results were apparent. The interdisciplinary interventions applied in all identified studies were found to reduce post-concussion symptoms across the symptom subtypes: headache/migraine, vestibular, cognitive, ocular motor and anxiety/mood.

CONCLUSIONS

The results demonstrated evidence for a reduction in persistent post-concussion symptoms following interdisciplinary intervention. This evidence will inform health services, clinicians, sports administrators and researchers with regard to concussion clinic and rehabilitation team design and service delivery.

Occupational Therapy Practice Guidelines for Adults With Traumatic Brain Injury

IMPORTANCE

Occupational therapy practitioners are uniquely qualified to address the occupational needs of people with traumatic brain injury (TBI) and their caregivers to maximize participation, health, and well-being.

OBJECTIVE

These Practice Guidelines are informed by systematic reviews of the effectiveness of interventions that address impairments and skills to improve the occupational performance of people with TBI, as well as interventions for caregivers of people with TBI. The purpose of these guidelines is to summarize the current evidence available to assist clinicians' clinical decision-making in providing interventions for people with TBI and their caregivers.

METHOD

We reviewed six systematic reviews and synthesized the results into clinical recommendations to be used in occupational therapy clinical practice.

RESULTS

Sixty-two articles served as the basis for the clinical recommendations.

CONCLUSIONS AND RECOMMENDATIONS

Strong to moderate evidence supports multimodal sensory stimulation, unimodal auditory stimulation, physical activity, virtual reality, cognitive interventions, vision therapy, goal-focused interventions, individual and group training and education, and caregiver supports. Occupational therapy practitioners should incorporate these interventions into individual and group sessions to maximize recovery and promote occupational participation. Additional interventions are also available, based on emerging evidence and expert opinion, including prevention approaches, complexity of injury, and the use of occupation-based performance assessments. What This Article Adds: These Practice Guidelines provide a summary of evidence in clinical recommendations tables supporting occupational therapy interventions that address impairments resulting from and skills to improve occupational performance after TBI. The guidelines also include case study examples and evidence graphics for practitioners to use to support clinical reasoning when selecting interventions that address the goals of the person with TBI and their caregiver's needs.

Double Vision and Light Sensitivity Symptoms are Associated With Return-to-School Timing After Pediatric Concussion

OBJECTIVE

To determine the association between academic time loss postconcussion and vision symptoms/impairments among pediatric patients.

DESIGN

Cross-sectional.

SETTING

Sports medicine clinic.

PATIENTS

Pediatric patients seen for care in a sports medicine clinic between the ages 6 and 18 years (n = 212; mean age = 14.3, SD = 2.4 years; 48% female) were evaluated within 21 days of concussion (mean = 9.8, SD = 5.7 days).

INDEPENDENT VARIABLE

Patients were grouped based on academic time loss (missed >5 days vs ≤5 days of school) at their initial postconcussion evaluation.

OUTCOME MEASURES

Patients rated concussion symptoms using the Health and Behavior Inventory (HBI) and underwent near point of convergence (NPC) testing. We compared groups on specific HBI symptom ratings of dizziness, blurry vision, seeing double, and light sensitivity, as well as NPC break and recovery point distances.

RESULTS

Two hundred twelve patients were included; n = 36 (17%) who reported missing >5 days of school. After adjusting for time since injury, parental education level, mechanism of injury, and preinjury anxiety, patients who reported missing >5 days of school had higher ratings of double vision (β = 0.27; 95% confidence interval [CI], 0.01-0.53; P = 0.04) and light sensitivity (β = 0.506; 95% CI, 0.061-0.951; P = 0.02), but not dizziness (β = 0.390; 95% CI, -0.047 to 0.827; P = 0.08) or blurry vision (β = 0.026; 95% CI, -0.352 to 0.404; P = 0.89).

CONCLUSION

Missing >5 days of school was associated with worse double vision and light sensitivity symptoms. Given the importance of vision in learning, assessing postconcussion vision symptoms may facilitate a successful return to school. Clinicians should assess a wide spectrum of vision-specific symptoms to ensure appropriate support during the return-to-school process.

Revised Dual Task Screen is a Valid Measure of Dual Task Performance: Developing a Motor and Cognitive Dual Task Measure with Healthy Female Athletes

Multitasking measures, such as dual task assessments, are particularly useful in detecting subtle deficits that can influence occupational performance after injuries, like sports-related concussion (SRC). In past work, our research team developed and revised a dual task assessment, the Dual Task Screen (DTS). Here, we evaluated nineteen healthy athletes using the revised DTS to address two specific research objectives. First, to replicate pilot study findings and demonstrate that the revised DTS is sensitive to dual task motor costs (i.e. poorer motor performance under dual task conditions, compared to single task conditions). Second, to evaluate if the revised DTS is sensitive to dual task cognitive costs (i.e. poorer cognitive performance under dual task conditions, compared to single task conditions). We confirmed that the revised DTS was sensitive to both dual task motor and cognitive costs; thus it is a valid measure of dual task performance. These positive findings support its prospective, future use by occupational therapists to evaluate multitasking performance after injuries, like SRC, or other injuries and illnesses that elicit deficits affecting optimal occupational performance.

Current Use and Future Considerations for Concussion Telemedicine Healthcare in Canada

OBJECTIVE

To examine the use of telemedicine among Canadian concussion providers and clinics before and after the COVID-19 pandemic onset and identify barriers and facilitators for future use.

METHODS

Ninety-nine concussion clinics and healthcare providers across Canada that offered one or more clinical concussion-related service were identified using standardized online searches and approached to complete a cross-sectional online survey.

RESULTS

Thirty clinics or providers completed the survey and two completed subsections of the survey (response rate of 32.3%). Only 28.1% of respondents indicated that they used telemedicine to provide care prior to the COVID-19 pandemic. Providers most commonly using telemedicine prior to the pandemic were occupational therapists and physicians, while the most commonly used services were in-person videoconferencing and eConsultation. Most respondents (87%) indicated their clinic's use of telemedicine changed following the onset of the COVID-19 pandemic including new use of in-person video-conferencing, telephone calls, and eConsultation. Ninety-three percent indicated that they would consider using telemedicine to provide care to their concussion patients once the pandemic was over. Barriers needed to be overcome to facilitate use or greater use of telemedicine-based services were the inability to conduct a complete physical examination, lack of appropriate reimbursement, lack of start-up, and maintenance funding and medico-legal risk.

CONCLUSION

Telemedicine was used by a minority of Canadian concussion clinics and providers prior to the COVID-19 pandemic but was rapidly adopted by many facilities. This study provides important insight into the factors that must be considered to optimize use of telemedicine in concussion care in the future.

Return-to-Activity: Exploration of Occupational Therapy in Outpatient Adult Concussion Rehabilitation

Literature is sparse related to how occupational therapy advances symptom management and role-activity resumption after concussion. We aim to describe the occupational therapy process of evaluation and intervention for adults with a history of concussion(s) and persisting symptoms. The qualitative descriptive study used focus groups of expert occupational therapy practitioners across practice settings. Content analysis with a deductive strategy, open coding, and an unconstrained matrix was used to determine the process portion of a logic model outlining how expert practitioners framed their approach to rehabilitation. Thirteen expert occupational therapy practitioners informed the development of a logic model describing the occupational therapy process linking resources to activities of evaluation and intervention enabling people to return to their everyday life roles at their highest capacity. This study yields a description of how occupational therapy practitioners, across practice settings, aid individuals in returning to everyday activities and life roles after concussion(s).

Tele-Active Rehabilitation for Youth With Concussion: Evidence-Based and Theory-Informed Intervention Development

BACKGROUND

Active rehabilitation involving subsymptom threshold exercise combined with education and support promotes recovery in youth with concussion but is typically delivered in person, which may limit accessibility for families because of a lack of services in their communities or logistical challenges to attending in-person sessions.

OBJECTIVE

This paper describes the evidence-based and theory-informed development of the Tele-Active Rehabilitation (Tele-AR) intervention for pediatric concussion, which was specifically designed for remote service delivery.

METHODS

The intervention was designed by clinician-researchers with experience in pediatric concussion rehabilitation following the Medical Research Council guidance for developing complex interventions. Development involved a critical review of the literature to identify existing evidence, the expansion of the theoretical basis for active rehabilitation, and the modeling of the intervention process and outcomes.

RESULTS

Tele-AR is a 6-week home exercise and education and support program facilitated through weekly videoconferencing appointments with a clinician. Exercise consists of low- to moderate-intensity subsymptom threshold aerobic activity and coordination drills that are individualized to participant needs and interests (prescribed for 3 days per week). Education includes the evidence-supported Concussion & You self-management program, which covers topics related to energy management, nutrition, hydration, sleep hygiene, and return to activity. Elements of self-determination theory are incorporated to support motivation and engagement. We present a logic model describing predicted intervention effects using a biopsychosocial conceptualization of outcomes after concussion.

CONCLUSIONS

The Tele-AR intervention may help to increase access to care that improves recovery and promotes a timely return to activity in youth with concussion. Future research is needed to evaluate the feasibility and efficacy of this approach.

Healthcare utilization and costs associated with persistent post-concussive symptoms

OBJECTIVE

To describe the healthcare utilization and costs associated with the interdisciplinary treatment of pediatric persistent post-concussive symptoms (PPCS).

METHODS

A retrospective chart review was conducted with 461 youth referred by community physicians to an interdisciplinary pediatric PPCS outpatient clinic in Ontario, Canada. Healthcare utilization parameters included accessibility, continuity, comprehensiveness, and service productivity. Direct healthcare costs included those incurred by physicians and other interdisciplinary services. Indirect costs per client included travel to the clinic and caregiver productivity loss. Data analyses were completed using descriptive statistics.

RESULTS

The median age of clients was 15 years (range = 3 to 18). The median wait time for an initial PPCS clinic physician consultation was 71 days, and less than 2 months for other interdisciplinary services. Eighty-two percent of clients were referred to at least one other service after an initial physician consultation. Occupational therapy received the highest proportion of referrals (79%). Total median direct costs per client were approximately $915, with a final accumulated cost of $532 623 for all clients. Caregiver productivity loss was approximately $387 per family.

CONCLUSIONS

Our findings suggest that interdisciplinary PPCS care represents an accessible, comprehensive and cost-saving healthcare model from the client and societal perspectives.

Risk Factors Associated With the Prescription of Opioids Among Service Members Following a First Mild Traumatic Brain Injury

OBJECTIVE

To evaluate factors impacting opioid receipt among active-duty service members (SMs) following a first mild traumatic brain injury (mTBI).

SETTING

Active-duty SMs receiving care within the Military Health System.

PARTICIPANTS

In total, 14 757 SMs who have sustained an initial mTBI, as documented within electronic health records (EHRs), between 2016 and 2017.

DESIGN

A retrospective analysis of EHR metadata.

MAIN MEASURES

Multivariable logistic regression assessed factors impacting opioid receipt and initiation. Factors include demographics, military characteristics, and preexisting clinical conditions, including prior opioid prescription.

RESULTS

Of the sample population, 33.4% (n = 4927) were prescribed opioids after their initial mTBI, of which, 60.6% (n = 2985) received opioids for the first time following injury. Significant risk factors associated with the increased probability of opioid receipt included age, gender, and preexisting behavioral health and musculoskeletal conditions. Military characteristics also exhibited changes in the probability of opioid receipt, both among initiation and new prescription. No changes were observed among race, nor among those with preexisting headaches or migraines.

CONCLUSION

Despite concerns about the negative impact on recovery, the prescribing of opioids is common in this population of active-duty SMs first diagnosed with an mTBI. As several demographic and preexisting health conditions are factors in the receipt of opioids post-mTBI, the entire medical history of these patients should be considered prior to prescription. Understanding these factors may further inform policy for opioid use in the Military Health System.

Models for Treating Post-traumatic Headache

PURPOSE OF REVIEW

To discuss the treatment of post-traumatic headache (PTH) and how to choose pharmacotherapy based upon known pathophysiology.

RECENT FINDINGS

Preclinical models of traumatic brain injury are finally revealing some of the mechanisms of PTH, including the significant role that inflammatory neuropeptides like calcitonin gene-related peptide (CGRP) play in the initiation and persistence of symptoms. To effectively treat post-traumatic headache (PTH), one needs to understand the pathophysiology behind the initiation and persistence of symptoms. Recent animal models are starting to elucidate these mechanisms, but effective treatment will also likely rely on the identification of patients who are most at risk for persistent PTH. Trials of early, targeted therapy for at-risk patients will be needed to validate these hypotheses. Additionally, high powered clinical trials are lacking in the field of persistent PTH for medications that are known to be effective in primary headache disorders. Effective treatment for persistent PTH also requires understanding how headache interacts with the complex nature of persistent post-concussion symptoms, as this disease often necessitates a multi-disciplinary approach. Regardless, with the knowledge gained by new PTH models cited in this paper, and an increasing availability of novel headache medications, more effective treatment models are on the horizon.
