Expanding Integrated Physiatric Care: A Method to Building Capacity in Physical Medicine and Rehabilitation.

ABSTRACT: Siloed and episodic care delivery is often not equitable, high-quality, or sustainable. Transitioning from separate care settings, with potentially divergent care models, to an integrated care model is not always straightforward. Some experiences in expanding collaborative care between physiatrists and other healthcare providers for a variety of patient populations and care settings within a university physical medicine and rehabilitation (PM&R) division are shared as a means to inspire the uptake of care integration initiatives more broadly within the specialty. After an initial survey of care integration across multiple clinical sites, the university division: highlighted successful integrated care models; discussed integrated care models at every divisional retreat; reached out to clinicians in other specialties to collaboratively explore expansion; developed a "one-pager" on what physiatrists do; and invited collaborative specialists from integrated clinics to PM&R national and/or international meetings. Since 2019, divisional activity in integrated care has grown and evolved substantially. Future work will focus on: further expansion of integrated clinical care; scholarly evaluation of integrated care models; expansion of academic activity resulting from integration; and advocacy to healthcare providers, hospital administrators, and health system funders about the potential value of care integration in improving rehabilitation outcomes.

Venous Thromboembolism Prevention in Rehabilitation: a Review and Practice Suggestions.

ABSTRACT: Venous thromboembolism (VTE) is a frequent complication of acute hospital care, and this extends to in-patient rehabilitation. The timely use of appropriate thromboprophylaxis in patients who are at risk is a strong, evidence-based patient safety priority that has reduced clinically important VTE, associated mortality and costs of care. While there has been extensive research on optimal approaches to VTE prophylaxis in acute care, there is a paucity of high-quality evidence specific to patients in the rehabilitation setting, and there are no clinical practice guidelines that make recommendations for (or against) thromboprophylaxis across the broad spectrum of rehabilitation patients. Herein, we provide an evidence-informed review of the topic with practice suggestions. We conducted a series of literature searches to assess the risks of VTE and its prevention related to in-patient rehabilitation as well as in major rehabilitation subgroups. Mobilization alone does not eliminate the risk of VTE after another thrombotic insult. Low molecular weight heparins (LMWHs) and direct oral anticoagulants (DOACs) are the principal current modalities of thromboprophylaxis. Based on the literature, we make suggestions for VTE prevention and include an approach for consideration by rehabilitation units that can be aligned with local practice.

Piriformis syndrome.

Piriformis syndrome is a condition that is proposed to result from compression of the sciatic nerve, either in whole or in part, in the deep gluteal space by the piriformis muscle. The prevalence of piriformis syndrome depends upon the diagnostic criteria being used and the population studied but is estimated by some to be 5%-6% in all cases of low back, buttock, and leg pain and up to 17% of patients with chronic low back pain. While the sciatic nerve may pierce the piriformis muscle in about 16% of healthy individuals, this frequency is no different in those with the syndrome; thus, the relationship to this anatomic finding is unclear. The most common symptoms are buttock pain, external tenderness over the greater sciatic notch, and aggravation of the pain through sitting. Many clinical signs are reported for piriformis syndrome, but the sensitivity and specificity are unclear, in part because of the lack of a uniformly accepted case definition. In the majority of cases in the literature, it appears that the diagnosis is more ascribed to a myofascial condition rather than a focal neuropathy. Electrodiagnostic studies can be useful to exclude other causes of symptoms, but there is no well-accepted test to confirm the presence of piriformis syndrome. Ultrasound imaging may show thickening of the piriformis muscle, but further research is required to confirm that this is correlated with the clinical diagnosis. Magnetic resonance imaging and neurography may hold promise in the future, but there are not yet sufficient data to support adopting these methods as a standard diagnostic tool. The initial treatment of piriformis syndrome is typically conservative management with the general rehabilitation principles similar to other soft tissue musculoskeletal conditions. Local anesthetic, botulinum toxin, and/or corticosteroid injections have been reported by some to be beneficial for diagnostic or treatment purposes. Surgical interventions have also been used with variable success.

Serial electrodiagnostic testing: Utility and indications in adult neurological disorders.

Although existing guidelines address electrodiagnostic (EDX) testing in identifying neuromuscular conditions, guidance regarding the uses and limitations of serial (or repeat) EDX testing is limited. By assessing neurophysiological change longitudinally across time, serial electrodiagnosis can clarify a diagnosis and potentially provide valuable prognostic information. This monograph presents four broad indications for serial electrodiagnosis in adult peripheral neurological disorders. First, where clinical change has raised suspicion for a new or ongoing lesion, EDX reassessment for spatial spread of abnormality, involvement of previously normal muscle or nerve, and/or evolving pathophysiology can clarify a diagnosis. Second, where diagnosis of a progressive neuromuscular condition is uncertain, electrophysiological data from a second time point can confirm or refute suspicion. Third, to establish prognosis after a static nerve injury, a repeat study can assess the presence and extent of reinnervation. Finally, faced with a limited initial study (as when complicated by patient or environmental factors), a repeat EDX study can supplement missing or limited data to provide needed clarity. Repeat EDX studies carry certain limitations, however, such as with prognostication in the setting of remote or chronic lesions, sensory predominant fascicular injury, or mild axonal injury. Nevertheless, serial electrodiagnosis remains a valuable and underused tool in the diagnostic and prognostic evaluation of neuromuscular conditions.

Electrodiagnostic reporting preferences of referring physicians: An exploratory survey.

INTRODUCTION/AIMS: Electrodiagnostic (EDX) studies play a crucial role in the evaluation of patients with peripheral nervous system disorders. Accurate and succinct communication of test results is critical to patient safety and clinical decision-making. The objective of this study was to explore EDX reporting preferences of referring physicians to improve quality of communication and patient care. METHODS: An online survey was developed, and a purposive sampling strategy was used to recruit physicians in the authors' professional networks. Quantitative and qualitative survey data underwent frequency and thematic analyses, respectively. RESULTS: There were 40 respondents, including: 21 non-surgical specialists, 12 surgical specialists, and 7 family physicians. Sections rated as most critical were diagnostic impression (97%) and summary/interpretation (72%). Only 18% reported numeric data as critical to their needs, preferring this data to be formatted as bullet points or tables without nerve conduction study waveforms. Regarding the format of the data summary and diagnostic impression sections, the majority of respondents preferred bullet points rather than paragraphs. DISCUSSION: The results of this exploratory survey suggest that physicians who refer patients for EDX studies prefer reports that emphasize the interpretation of EDX data and a clear diagnostic impression, particularly in bullet point format. This project highlights important preferences and how they compare to recommended reporting guidelines, which may help improve communication and ultimately patient care. Future efforts should explore larger sample sizes with all key stakeholders in the EDX process to better understand reporting styles and preferences with greater nuance and context.

Motor Unit Number Index of the Upper Trapezius: A Meta-Analysis and Cross-sectional Study of Its Reliability.

Motor unit number index of the upper trapezius (MUNIX-Trapezius) is a candidate biomarker for bulbar lower motor neuron function; however, reliability data is incomplete. To assess MUNIX-Trapezius reliability in controls, we conducted a systematic review, a cross-sectional study (n = 20), and a meta-analysis. We demonstrated a high inter- and intra-rater intraclass correlation (0.86 and 0.94, respectively), indicating that MUNIX-Trapezius is reliable with between-study variability moderated by age and MUNIX technique. With further validation, this measure can serve as a disease monitoring and response biomarker of bulbar function in the therapeutic development for amyotrophic lateral sclerosis.

Provocative changes in nerve conductions: Fact or fiction?

At times electrodiagnostic medical consultants (EMCs) are asked to perform studies in both a neutral position, and then again after the patient is in a provocative position that exacerbates symptoms, to assess for measurable electrophysiologic changes. While this approach might seem initially appealing, particularly when standard studies are not effective at diagnosis, empiric studies in several conditions have been unimpressive. Studies in median neuropathy at the wrist, thoracic outlet syndrome, piriformis syndrome, and radial tunnel syndrome have failed to demonstrate reproducible changes in nerve conduction studies in positions that exacerbate symptoms. Furthermore, there is lack of a plausible pathophysiologic mechanism for producing both measurable and rapidly reversible electrophysiologic changes after just a few minutes, or less, of compression. Axon loss and demyelination would not be rapidly reversible, and positional changes of 2 min or less (the durations generally studied) would be insufficient to produce measurable nerve ischemia. Last, we have gained a greater appreciation for how much nerves move within limbs with changes in joint position; this movement can lead to misleading changes in nerve conduction studies. It is thus appropriate to conclude that testing nerve conduction in provocative or symptomatic positions adds no value to electrodiagnostic testing.

Comparison of electrodiagnostic findings in acute traumatic versus chronic non-traumatic ulnar neuropathy at the elbow.

INTRODUCTION/AIMS: A common concept is that traumatic nerve injuries are more likely axonal, and that compressive neuropathies are more likely demyelinating. The purpose of this study was to compare traumatic versus non-traumatic ulnar neuropathy at the elbow (UNE) to look for electrodiagnostic differences between the two groups. METHODS: A retrospective 3 year review of UNE patients at two academic health science centers was conducted. Patients were grouped into acute traumatic UNE versus chronic non-traumatic UNE based on clinical history. Electrodiagnostic measurements were compared between the two groups. RESULTS: There were 50 subjects with acute traumatic UNE and 41 with chronic non-traumatic UNE. Mean age and sex distribution were similar but those with traumatic UNE had a 7 month duration of symptoms, while those with chronic UNE had 29 month duration (p < .001). All electrodiagnostic measurements were similar between the two groups including compound muscle action potential amplitudes, motor conduction velocities, frequency of conduction block, sensory nerve studies, and needle electromyography. DISCUSSION: We did not find a difference between the two groups. One should not make inferences regarding acuity or etiology based on electrodiagnostic features alone.

Training factors that influence electrodiagnostic medicine knowledge.

INTRODUCTION/AIMS: Self-assessment examinations (SAEs) help trainees assess their progress in education. SAEs also provide feedback to training programs as to how factors in training influence examination performance. This study's goal was to examine the relationship between the number of months of training in electrodiagnostic (EDx) medicine, the number of EDx studies during training, and scores on the American Association of Neuromuscular and Electrodiagnostic Medicine SAE. METHODS: This was a retrospective study of the 2023 AANEM-SAE results. In addition to the examination score, participants were asked approximately how many EDx studies they performed in training and how many months of training they had completed. Analysis included correlation of the examination scores with months of training as well as number of EDx studies. In addition, a multivariate linear regression model was developed. RESULTS: A total of 756 participants completed the proctored examination in May 2023. Examination score was moderately and positively correlated with the number of months of training (Pearson r = .5; p < .001) as well as the number of EDx studies during training (Pearson r = .55; p < .001). Scores steadily improved with additional months of training, but leveled off after 300-400 EDx studies. Regression analysis indicated that higher numbers of EDx studies were correlated with a higher examination score even after accounting for the number of months of study. DISCUSSION: We believe that a greater number of months of training is associated with better performance on the AANEM-SAE and that greatest improvement in examination performance occurs during the first 300-400 EDx studies.

Patients, Caregivers, and Healthcare Providers' Experiences with COVID Care and Recovery across the Care Continuum: A Qualitative Study.

Introduction: During the COVID-19 pandemic, discharge timelines were accelerated and patients were moved across the continuum of care, from acute to post-acute care, to relieve the strain in health system capacity. This study aimed to investigate the COVID-19 care pathway from the perspective of patients, caregivers, and healthcare providers to understand their experiences with care and recovery within and across care settings. Methods: A qualitative descriptive study. Patients and their families from an inpatient COVID-19 unit and healthcare providers from an acute or rehabilitation COVID-19 unit were interviewed. Results: A total of 27 participants were interviewed. Three major themes were identified: 1) The perceived quality and pace of COVID-19 care improved from acute care to inpatient rehabilitation; 2) Care transitions were especially distressing; and 3) Recovery from COVID-19 stagnated in the community. Conclusion: Inpatient rehabilitation was viewed as higher quality due to the slower paced care. Care transitions were distressing for stakeholders and enhanced integration between acute and rehabilitation care were suggested to improve patient handover. A lack of rehabilitation access led to recovery stagnating for patients discharged to the community. Telerehab may improve the transition to home and ensure access to adequate rehabilitation and support in the community.

Characteristics and healthcare utilization of COVID-19 rehabilitation patients during the first and second waves of the pandemic in Toronto, Canada.

The objective of this study is to describe the healthcare utilization, and clinical and sociodemographic features of a cohort of 74 coronavirus disease 2019 (COVID-19) patients admitted to a tertiary rehabilitation hospital in Toronto, Canada. A retrospective chart review was performed using 74 charts from patients admitted to a COVID-19 rehabilitation unit between 11 April 2020 and 30 April 2021. Measures of central tendency, SDs, interquartile ranges, frequencies, and proportions were calculated to analyze clinical and sociodemographic data. A total of 74 patients were included in this study, including 33 males and 41 females. The mean age was 72.8 years, with Wave 1 patients being younger than Wave 2 patients. Sixty-six percent of total patients experienced hypertension. Mean functional independence measure score across both waves was 78 at admission and 100 at discharge. Mean length of stay was 14.6 days in Wave 1 and 18.8 days in Wave 2. This study represents some of the first data on the characteristics and outcomes of COVID-19 patients admitted to inpatient rehabilitation in Toronto, Canada across the initial waves of the COVID-19 pandemic.

Psychosocial group therapy interventions for patients with physical disabilities: A scoping review of implementation considerations.

OBJECTIVE: Group therapy is an intervention that that has been well-studied in patients with medical illness and shown to optimize patients' wellbeing and mental health resource utilization. However, its implementation and effectiveness have not been adequately studied in those with physical disabilities. This review addresses current gaps by synthesizing the literature to examine implementation considerations in the use of psychosocial group therapy for anxiety and depression in individuals with physical disabilities. METHOD: This review adhered to Arksey and O'Malley's methodological framework and the Preferred Reporting Items for Systematic Reviews and Meta-analyses extension for Scoping Reviews Checklist. Studies were identified through MEDLINE, EMBASE, PSYCINFO, and CINAHL. Included studies were qualitative, quantitative, or mixed methods research on participants with a physical disability, and undergoing psychosocial group therapy to address anxiety/depression. RESULTS: Fifty-five studies were included in the review. The most common physical disabilities were multiple sclerosis (n = 31) and Parkinson's disease (n = 13). Group Cognitive Behavioral Therapy was the most commonly used intervention, facilitated by individuals with formal mental health training. A majority of therapy sessions included cohorts of up to 10 patients, and occurred weekly. Almost half of the studies (n = 27) reported high adherence rates (80%-99%), and a large proportion found group therapy led to improvements in their samples on a range of outcomes. CONCLUSION: Group therapies to address anxiety and depression are diverse, widely used, effective, and well-adhered to. This review may help practitioners develop, implement, and evaluate group programming for individuals with physical disabilities to address anxiety and depression.

An overview of the rehabilitation and psychiatric diagnoses of patients referred to a psychiatry consult liaison service at an inpatient rehabilitation hospital.

BACKGROUND: Patients presenting for inpatient rehabilitation following injury or illness are commonly affected by comorbid psychiatric illness. Currently, little is known about the utilization of a psychiatry consult service in an inpatient rehabilitation hospital. OBJECTIVE: To identify which rehabilitation patient populations most frequently received psychiatric consultation and recognize the most common psychiatric comorbidities after the implementation of a psychiatry consult liaison (PCL) service. DESIGN: A retrospective observational study in the form of a chart review examining the utilization patterns of a psychiatric consultation liaison service in the inpatient rehabilitation setting. Chart review was performed to extract patient demographics (age and sex), rehabilitation diagnosis, cause of rehabilitation diagnosis (intentional, accident, self-inflicted, or disease), reason for referral to psychiatry, and psychiatric diagnosis on initial consultation. Statistical software was used for statistical analysis to answer the pre-specified research questions. SETTING: A 178 bed, free-standing, academic rehabilitation hospital located in an urban Canadian center. PATIENTS: Any patient admitted to the inpatient rehabilitation hospital who received a psychiatric consultation between September 2016 and December 2019 was eligible for inclusion. RESULTS: A total of 1016 charts were reviewed in the initial chart review and  1008 were included. The most common rehabilitation diagnoses that were associated with a psychiatric consult were (% admissions receiving consultation): amputations (38%); burns (35%), neurologic disorder (28%), deconditioning (14%), and musculoskeletal injury (7%). Although 20% of patients did not meet criteria for a psychiatric diagnosis, most common psychiatric diagnoses included mood disorder, adjustment disorder, neurocognitive disorder, and delirium. CONCLUSION: There are significant perceived needs for psychiatric services in the inpatient rehabilitation setting. Although some patient groups such as patients with amputations, burns, and trauma may exhibit the highest utilization, the service supports mental health needs from many patient groups.
