Residency spiral concussion curriculum design.

BACKGROUND: Resident-focused concussion curricula that measure learner behaviours are currently unavailable. We sought to fill this gap by developing and iteratively implementing a Spiral Integrated Concussion Curriculum (SICC). APPROACH: Programme elements of the concussion curriculum include academic half-days (AHDs) and three half-day clinics for first- and second-year family medicine residents. Our SICC utilises social cognitive learning principles, the constructivism paradigm and utilisation-focused evaluation. EVALUATION: A mixed-method evaluation with a pre-/post-test design and interviews was utilised. Surveys and knowledge tests were used to measure knowledge and confidence pre-AHD and 6 months post-AHD. Interviews at 6 months explored programme perception and behaviour change. Of the 141 programme attendees, 114 (80%) participated in the pre-intervention knowledge test and 33 completed the pre- and post-AHD test. Immediate pre-/post-testing demonstrated statistically significant improvement in knowledge (p = 0.042). At 6 months post-AHD, residents in Cycle 1 (n = 5) had a knowledge decrease of 3.33% (p > 0.05). Residents in Cycle 2 (n = 7) had a knowledge increase of 11.6% (p > 0.05). Both cycles of residents had an increase in confidence (Cycle 1: 65.0% [p = 0.025]; Cycle 2: 62.8% [p = 0.0014]). Residents (5 out of 6) reported positive behavioural changes at 6 months. Valued programme elements included concussion diagnosis and management, the self-study guide resource and the organised structure. IMPLICATIONS: The SICC enriched these residents' learning and fostered sustained knowledge improvement and behavioural change at 6 months post-intervention. This approach may provide a workable design for future competency-based curriculum development.

The Toronto Concussion Study: a prospective investigation of characteristics in a cohort of adults from the general population seeking care following acute concussion, 2016-2020.

Purpose: There is limited research regarding the characteristics of those from the general population who seek care following acute concussion. Methods: To address this gap, a large cohort of 473 adults diagnosed with an acute concussion (female participants = 287; male participants = 186) was followed using objective measures prospectively over 16 weeks beginning at a mean of 5.1 days post-injury. Results: Falls were the most common mechanism of injury (MOI) (n = 137, 29.0%), followed by sports-related recreation (n = 119, 25.2%). Male participants were more likely to be injured playing recreational sports or in a violence-related incident; female participants were more likely to be injured by falling. Post-traumatic amnesia (PTA) was reported by 80 participants (16.9 %), and loss of consciousness (LOC) was reported by 110 (23.3%). In total, 54 participants (11.4%) reported both PTA and LOC. Male participants had significantly higher rates of PTA and LOC after their injury compared to their female counterparts. Higher initial symptom burden was associated with a longer duration of recovery for both male and female participants. Female participants had more symptoms and higher severity of symptoms at presentation compared to male participants. Female participants were identified to have a longer recovery duration, with a mean survival time of 6.50 weeks compared to 5.45 weeks in male participants (p < 0.0001). A relatively high proportion of female and male participants in this study reported premorbid diagnoses of depression and anxiety compared to general population characteristics. Conclusion: Although premorbid diagnoses of depression and/or anxiety were associated with higher symptom burden at the initial visit, the duration of symptoms was not directly associated with a pre-injury history of psychological/psychiatric disturbance. This cohort of adults, from the general population, seeking care for their acute concussion attained clinical and functional recovery over a period of 4-12 weeks.

Psychosocial Factors Associated with Prolonged Length of Stay in Acquired Brain Injury Rehabilitation: A Retrospective Cohort Study.

OBJECTIVE: In a climate of rising healthcare costs and increasing pressure to reduce inpatient length of stay, hospitals must balance their role as care providers with that as resource stewards. There is a need to understand what factors are associated with patients staying beyond rehabilitation length of stay targets. The aim of this study was to determine psychosocial patient factors that are identifiable on admission that influence length of stay targets in acquired brain injury rehabilitation. METHODS: A retrospective case series of 167 inpatients with acquired brain injury was conducted at an urban, academic rehabilitation hospital. A total of 29 factors were used for data analysis. Logistic and multiple linear regression analysis was utilized to determine if any patient factors were associated with patients exceeding their length of stay targets. RESULTS: Premorbid communal living status (e.g. group home) was associated with an odds ratio of 14.67 of exceeding length of stay target. Patients who did not drive prior to their admission had an odds ratio of 2.63 of exceeding their length of stay target. CONCLUSION: Premorbid communal living and premorbid non-driving status are predictors of patients with acquired brain injuries exceeding target rehabilitation length of stay. These findings may help acquired brain injury rehabilitation programmes plan for the needs of and advocate for patients.

Revisiting the ICHD-3 criteria for headache attributed to mild traumatic injury to the head: Insights from the Toronto Concussion Study Analysis of Acute Headaches Following Concussion.

BACKGROUND: There is limited prospective data on the prevalence, timing of onset, and characteristics of acute headache following concussion/mild traumatic brain injury. METHODS: Adults diagnosed with concussion (arising from injuries not related to work or motor vehicle accidents) were recruited from emergency departments and seen within one week post injury wherein they completed questionnaires assessing demographic variables, pre-injury headache history, post-injury headache history, and the Sport Concussion Assessment Tool (SCAT-3) symptom checklist, the Sleep and Concussion Questionnaire (SCQ) and mood/anxiety on the Brief Symptom Inventory (BSI). RESULTS: A total of 302 participants (59% female) were enrolled (mean age 33.6 years) and almost all (92%) endorsed post-traumatic headache (PTH) with 94% endorsing headache onset within 24 hours of injury. Headache location was not correlated with site of injury. Most participants (84%) experienced daily headache. Headache quality was pressure/squeezing in 69% and throbbing/pulsing type in 22%. Associated symptoms included: photophobia (74%), phonophobia (72%) and nausea (55%). SCAT-3 symptom scores, Brief Symptom Inventory and Sleep and Concussion Questionnaire scores were significantly higher in those endorsing acute PTH. No significant differences were found in week 1 acute PTH by sex, history of migraine, pre-injury headache frequency, anxiety, or depression, nor presence/absence of post-traumatic amnesia and self-reported loss of consciousness. CONCLUSIONS: This study highlights the very high incidence of acute PTH following concussion, the timing of onset and characteristics of acute PTH, the associated psychological and sleep disturbances and notes that the current ICHD-3 criteria for headaches attributed to mild traumatic injury to the head are reasonable, the interval between injury and headache onset should not be extended beyond seven days and could, potentially, be shorted to allow for greater diagnostic precision.

Stroke Recovery During the COVID-19 Pandemic: A Position Paper on Recommendations for Rehabilitation.

Health care delivery shifted and adapted with the COVID-19 pandemic caused by the novel severe acute respiratory syndrome coronavirus 2. Stroke care was negatively affected across the care continuum and may lead to poor community living outcomes in those who survived a stroke during the ongoing pandemic. For instance, delays in seeking care, changes in length of stays, and shifts in discharge patterns were observed during the pandemic. Those seeking care were younger and had more severe neurologic effects from stroke. Increased strain was placed on caregivers and public health efforts, and community-wide lockdowns, albeit necessary to reduce the spread of COVID-19, had detrimental effects on treatment and recommendations to support community living outcomes. The American Congress of Rehabilitation Medicine Stroke Interdisciplinary Special Interest Group Health and Wellness Task Force convened to (1) discuss international experiences in stroke care and rehabilitation and (2) review recently published literature on stroke care and outcomes during the pandemic. Based on the findings in the literature, the task force proposes recommendations and interdisciplinary approaches at the (1) institutional and societal level; (2) health care delivery level; and (3) individual and interpersonal level spanning across the care continuum and into the community.

The incidence and nature of adverse events in rehabilitation inpatients with acquired brain injuries.

BACKGROUND: Patient safety is important in all healthcare settings. Few studies have examined the state of patient safety in rehabilitation and none have examined patient safety in the setting of acquired brain injury (ABI) rehabilitation. OBJECTIVES: To determine the incidence, most common types, and severities of adverse events among inpatients undergoing ABI rehabilitation. DESIGN: Retrospective case series descriptive study. SETTING: The inpatient ABI rehabilitation program at an academic, tertiary rehabilitation hospital in Canada. PARTICIPANTS: One hundred eight consecutive inpatients with acquired brain injuries. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Patient charts and incident reports from the hospital's voluntary reporting system were reviewed by three board-certified physiatrists to determine the incidence, type, severity and preventability of adverse events. Adverse events were identified and classified for severity and type using the World Health Organization (WHO) International Classification for Patient Safety. Preventability was rated on a six-point Likert scale. RESULTS: During the study period, the incidence of adverse events was 17.42 ± 3.86 per 1000 patient days. Adverse events affected 52.8% of patients. Most adverse events identified were mild in severity (81.6%) and the rest were of moderate severity. The two most common types of adverse events were (1) patient incidents (50%) such as falls, pressure ulcers and skin tears and (2) patient behaviors such as missing patient, assault, or sexual behaviors (14.5%). Of the 76 adverse events identified in the study, 44.8% were preventable. The hospital's voluntary reporting system did not capture 57.9% of the adverse events identified. CONCLUSIONS: Future efforts to improve patient safety in ABI rehabilitation should focus on reducing falls, skin injuries and behaviors, and removing barriers to voluntary incident reporting. Detection of adverse events through chart reviews provides a more complete understanding of patient safety risks in ABI rehab than relying on incident reporting alone.

Can Sport Concussion Assessment Tool (SCAT) Symptom Scores Be Converted to Rivermead Post-concussion Symptoms Questionnaire (RPQ) Scores and Vice Versa? Findings From the Toronto Concussion Study.

Background: The Rivermead Post-Concussion Symptoms Questionnaire (RPQ) and the Sports Concussion Assessment Tool (SCAT) are widely used self-report tools assessing the type, number, and severity of concussion symptoms. There are overlapping symptoms and domains, though they are scored differently. The SCAT consists of 22 questions with a 7-point Likert scale for a total possible score 132. The RPQ has 16 questions and a 5-point Likert scale for a total of 64 possible points. Being able to convert between the two scores would facilitate comparison of results in the concussion literature. Objectives: To develop equations to convert scores on the SCAT to the RPQ and vice versa. Methods: Adults (17-85 years) diagnosed with a concussion at a referring emergency department were seen in the Hull-Ellis Concussion and Research Clinic, a rapid access concussion clinic at Toronto Rehab-University Health Network (UHN) Toronto Canada, within 7 days of injury. The RPQ and SCAT symptom checklists as well as demographic questionnaires were administered to all participants at Weeks 1, 2, 3, 4, 5, 6, 7, 8, 12, 16. Results: 215 participants had 1,168 matched RPQ and SCAT assessments. Total scores of the RPQ and the SCAT had a rho = 0.91 (p < 0.001); correlations were lower for sub-scores of specific symptom domains (range 0.74-0.87, p < 0.001 for all domain comparisons). An equation was derived to calculate SCAT scores using the number and severity of symptoms on the RPQ. Estimated scores were within 3 points of the observed total score on the SCAT. A second equation was derived to calculate the RPQ from the proportion weighted total score of the SCAT. This equation estimated corresponding scores within 3 points of the observed score on the RPQ. Conclusions: The RPQ and SCAT symptom checklists total scores are highly correlated and can be used to estimate the total score on the corresponding assessment. The symptom subdomains are also strongly correlated between the 2 scales however not as strongly correlated as the total score. The equations will enable researchers and clinicians to quickly convert between the scales and to directly compare concussion research findings.

Sleep disturbance and length of stay in the setting of acquired brain injury rehabilitation.

OBJECTIVE: The objective of this study was to investigate the impact and prevalence of sleep-wake disturbances among adult patients admitted for inpatient acquired brain injury rehabilitation. METHOD: This was a retrospective cohort study involving all adults admitted for inpatient ABI neurocognitive rehabilitation at UHN-Toronto Rehabilitation Institute over a 12-month period (n = 165). The primary endpoint of the study was the comparison of functional independent measure efficiency and hospital length of stay between patients reporting sleep disturbance (e.g. increased sleep latency, obstructive sleep apnea [OSA], sleep maintenance insomnia) versus those with normal sleep. RESULTS: We found that more than half (58.2%) of patients experienced sleep disturbance based on a combination of self-report and clinical documentation. The most common sleep disturbance was increased sleep onset latency (28.5%), followed by mixed sleep onset/maintenance insomnia (14.5%) and obstructive sleep apnea (8.5%). Notably, OSA was associated with longer length of hospital stay and reduced functional independence measure (FIM) efficiency in the cognitive domain after accounting for age and number of medical comorbidities. IMPLICATIONS: The results of this investigation underscore the importance of screening patients with brain injury for sleep disturbances due to its high prevalence and impact on rehabilitation efficiency.

Prediction of risk of prolonged post-concussion symptoms: Derivation and validation of the TRICORDRR (Toronto Rehabilitation Institute Concussion Outcome Determination and Rehab Recommendations) score.

BACKGROUND: Approximately 10% to 20% of people with concussion experience prolonged post-concussion symptoms (PPCS). There is limited information identifying risk factors for PPCS in adult populations. This study aimed to derive a risk score for PPCS by determining which demographic factors, premorbid health conditions, and healthcare utilization patterns are associated with need for prolonged concussion care among a large cohort of adults with concussion. METHODS AND FINDINGS: Data from a cohort study (Ontario Concussion Cohort study, 2008 to 2016; n = 1,330,336) including all adults with a concussion diagnosis by either primary care physician (ICD-9 code 850) or in emergency department (ICD-10 code S06) and 2 years of healthcare tracking postinjury (2008 to 2014, n = 587,057) were used in a retrospective analysis. Approximately 42.4% of the cohort was female, and adults between 18 and 30 years was the largest age group (31.0%). PPCS was defined as 2 or more specialist visits for concussion-related symptoms more than 6 months after injury index date. Approximately 13% (73,122) of the cohort had PPCS. Total cohort was divided into Derivation (2009 to 2013, n = 417,335) and Validation cohorts (2009 and 2014, n = 169,722) based upon injury index year. Variables selected a priori such as psychiatric disorders, migraines, sleep disorders, demographic factors, and pre-injury healthcare patterns were entered into multivariable logistic regression and CART modeling in the Derivation Cohort to calculate PPCS estimates and forward selection logistic regression model in the Validation Cohort. Variables with the highest probability of PPCS derived in the Derivation Cohort were: Age >61 years ([Formula: see text] = 0.54), bipolar disorder ([Formula: see text] = 0.52), high pre-injury primary care visits per year ([Formula: see text] = 0.46), personality disorders ([Formula: see text] = 0.45), and anxiety and depression ([Formula: see text] = 0.33). The area under the curve (AUC) was 0.79 for the derivation model, 0.79 for bootstrap internal validation of the Derivation Cohort, and 0.64 for the Validation model. A limitation of this study was ability to track healthcare usage only to healthcare providers that submit to Ontario Health Insurance Plan (OHIP); thus, some patients seeking treatment for prolonged symptoms may not be captured in this analysis. CONCLUSIONS: In this study, we observed that premorbid psychiatric conditions, pre-injury health system usage, and older age were associated with increased risk of a prolonged recovery from concussion. This risk score allows clinicians to calculate an individual's risk of requiring treatment more than 6 months post-concussion.

Effect of topical anesthetics on needle insertion pain during botulinum toxin type A injections for limb spasticity.

OBJECTIVE: To compare pain perception using 3 anesthetics (eutectic mixture of local anesthetics [EMLA], vapocoolant spray, and ice) compared with a control (no anesthetic) during botulinum toxin type A (BTX-A) injections for lower limb spasticity. DESIGN: A placebo-controlled, single-blinded study where each study patient served as their own control. SETTING: Spasticity clinic. PARTICIPANTS: Subjects (N=30) with ankle spasticity who visited the clinic for BTX-A injections in the gastrocnemius muscle were consecutively sampled. INTERVENTION: The gastrocnemius muscle was divided into 4 quadrants and 1 of the 3 different anesthetic agents was applied to each quadrant with 1 quadrant using no anesthetic, control. MAIN OUTCOME MEASURES: Numerical Rating Scale (NRS) and the Wong-Baker FACES scale. RESULTS: Pain perception using the NRS and FACES scale was significantly lower using ice and EMLA compared with control and spray conditions (P<.05). Pain perception using EMLA and ice was similar. These results indicate that patients experience minimal to moderate pain during BTX-A injections. CONCLUSIONS: Pain relief offered by EMLA and ice was comparable, suggesting that ice is a more convenient option because of brief application time (compared with EMLA). Spray may have made the patients more sensitive to pain and alternative approaches for using vapocoolant should be considered.

Cardiomyopathy presenting as severe fatigue in a person with chronic spinal cord injury.

BACKGROUND/OBJECTIVE: To describe a case of fatigue associated with cardiomyopathy in a man with spinal cord injury. STUDY DESIGN: Case report. SUBJECT: An obese 35-year-old man with long-term ASIA A L2 paraplegia, accompanied by a 2-year history of progressive severe fatigue. METHODS: Physical examination showed obesity, hypertension, tachycardia, and pitting edema. An echocardiogram showed a 20% ejection fraction, severe dilation, and global hypokinesis in the left ventricle and mild to moderate mitral regurgitation. RESULTS: Symptoms improved after treatment with furosemide, warfarin, ramipril, and continuous positive airway pressure for obstructive sleep apnea. CONCLUSION: Severe progressive fatigue in a patient with chronic SCI may signal cardiomyopathy. Diagnostic studies may be warranted in patients with progressive fatigue.
