Successful outcomes following neurorehabilitation in military traumatic brain injury patients in the United Kingdom

Consensus statement: An evidence-based review of exercise, rehabilitation, rest, and return to activity protocols for the treatment of concussion and mild traumatic brain injury

BACKGROUND

Early diagnosis and appropriate management of concussion/mild traumatic brain injury (mTBI) is critical for preventing poor outcomes and minimizing health care burden. Current clinical guidelines for concussion management focus mostly on diagnosis and return to cognitive and physical activity but provide limited guidance on the use of specific therapeutic interventions.

OBJECTIVE

To systematically review the available evidence on therapeutic interventions for concussion/mTBI and develop an evidence-based consensus statement on the use of these interventions in clinical practice.

LITERATURE SURVEY

A systematic literature search was performed first in 2018 and 2019, and again in 2022, to identify relevant original research on these interventions. A total of 6303 articles were retrieved through the systematic literature search and screened for inclusion. Eighty articles met inclusion criteria and were included in this review and consensus process.

METHODOLOGY

A multispecialty panel was convened to explore management of concussion/mTBI. Interventions evaluated included rest, exercise, rehabilitation, and return to activity (RTA) protocols. Studies were assessed for relevance and methodologic quality and were voted upon to develop an evidence-based consensus statement on the therapeutic appropriateness of these interventions for concussion/mTBI. A meta-analysis was not performed.

SYNTHESIS

There was sufficient evidence to recommend exercise as an appropriate therapy for adolescents with acute concussion/mTBI. In other age groups and for other therapeutic modalities, although some studies demonstrated benefits for some of the interventions, mixed results and study limitations prevented the panel from drawing firm conclusions on the efficacy of those interventions. The panel found evidence of detrimental effects from strict rest and high-intensity physical activity.

CONCLUSIONS

The panel recommended exercise as an appropriate therapy for acute concussion in adolescents. The evidence on other therapeutic interventions for concussion/mTBI remains limited to small randomized controlled trials and observational studies of moderate to low quality. The panel found no strong evidence to support or recommend against the other evaluated interventions but found most interventions to be safe when used judiciously and in consideration of individual patient needs. High-quality randomized studies with sufficient power are needed to evaluate the effects of rest, rehabilitation, and RTA protocols for the management of concussion/mTBI.

Predictors of Social Participation Outcome after Traumatic Brain Injury Differ According to Rehabilitation Pathways

Social participation (SP) is one of many objectives in the rehabilitation of patients with traumatic brain injury (TBI). Studies on predictors of SP specific to post-acute universally accessible specialized rehabilitation pathways following TBI are scarce. Our objectives were to: 1) characterize SP, as well as a set of pre-injury, injury-related, and post-injury variables in individuals participating in inpatient-outpatient or outpatient rehabilitation pathways within a universally accessible and organized trauma continuum of care; and 2) examine the ability of pre-injury, injury-related, and post-injury variables in predicting SP outcome after TBI according to rehabilitation path. Participants (N = 372) were adults admitted to an inpatient-outpatient rehabilitation pathway or an outpatient rehabilitation pathway after sustaining a TBI between 2016 and 2020, and for whom Mayo-Portland Adaptability Intentory-4 (MPAI-4) outcomes were prospectively obtained at the start and end of rehabilitation. Additional data was collected from medical files. For both rehabilitation pathways, predicted SP outcome was MPAI-4 Participation score at discharge from outpatient rehabilitation. Multiple regression models investigated the predictive value of each variable for SP outcome, separately for each care pathway. Main findings show that for the inpatient-outpatient sample, three variables (education years, MPAI-4 Ability and Adjustment scores at rehabilitation intake) significantly predicted SP outcome, with the regression model accounting for 49% of the variance. For the outpatient sample, five variables (pre-morbid hypertension and mental health diagnosis, total indirect rehabilitation hours received, MPAI-4 Abilities and Adjustment scores at rehabilitation intake) significantly predicted SP outcome, with the regression model accounting for 47% of the variance. In conclusion, different pre-morbid and post-injury variables are involved in predicting SP, depending on the rehabilitation path followed. The predictive value of those variables could help clinicians identify patients more likely of showing poorer SP at discharge and who may require additional or different interventions.

Review of neurological rehabilitation for Multiple Sclerosis in the British Military

Multiple sclerosis (MS) is a progressive neurological disorder, classically presenting in working age adults, including those in the Armed Forces. The Defence Medical Rehabilitation Centre (DMRC) Stanford Hall offers vocationally focused neurorehabilitation services for service personnel (SP) with MS, with the goal to minimise disability, maximise independence and remain able to work.This paper has two aims. First, it briefly provides a clinical update of MS, focusing on pathology, presentation, diagnosis and management. Finally, it will describe the role of DMRC and data from the last decade in the management of MS.Our findings suggest not all SP with MS are being referred to DMRC, and some of those who do have significant delays, potentially impacting on patient support, symptom management and occupational outcomes. It is hoped that this paper will improve awareness and recognition of MS for Armed Forces personnel.

Validation of the Mayo-Portland Adaptability Inventory-4 (MPAI-4) and reference norms in a French-Canadian population with traumatic brain injury receiving rehabilitation

PURPOSE

Validate the factor structure and establish internal consistency reliability of the French-Canadian version of the Mayo-Portland Adaptability Inventory (MPAI-4), using a Canadian sample of adults with traumatic brain injury (TBI) receiving post-acute rehabilitation services.

MATERIALS AND METHODS

Psychometric analysis of French-Canadian MPAI-4 data from TBI adults (N = 1012) who received rehabilitation interventions and for whom a first French-Canadian MPAI-4 measure was completed between 2016 and 2020.

RESULTS

Exploratory factor analysis was used to evaluate the factor structure of the French-Canadian MPAI-4. The final and best solution revealed three factors, which accounted for 48.68% of the variance. Using Cronbach's alpha, all subscales showed good internal consistency (all 0.70 ≤ α ≤ 0.89). Reference norms for the TBI sample are provided, as well as descriptive raw data according to sex, age, TBI severity and rehabilitation setting.

CONCLUSIONS

The French-Canadian MPAI-4 factor structure is validated. The three factors extracted are similar to the three subscales of the original MPAI-4. The questionnaire shows good psychometric properties and represents a suitable tool for TBI adults receiving rehabilitation services in a French-Canadian context. The provided reference norms will also help guide the clinical use of the MPAI-4 in French-Canadian TBI populations.Implications for rehabilitationThe MPAI-4 questionnaire measures functional abilities, global outcome and community integration following traumatic brain injury (TBI).The questionnaire can be used in inpatient, outpatient and vocational rehabilitation settings to assess TBI patients' progress and outcomes, plan interventions and evaluate the effect of rehabilitation.The French-Canadian version of the MPAI-4 is validated and suitable to be used in French-Canadian post-acute TBI rehabilitation settings.

Study protocol for a prospective, longitudinal cohort study investigating the medical and psychosocial outcomes of UK combat casualties from the Afghanistan war: the ADVANCE Study

INTRODUCTION

The Afghanistan war (2003-2014) was a unique period in military medicine. Many service personnel survived injuries of a severity that would have been fatal at any other time in history; the long-term health outcomes of such injuries are unknown. The ArmeD SerVices TrAuma and RehabilitatioN OutComE (ADVANCE) study aims to determine the long-term effects on both medical and psychosocial health of servicemen surviving this severe combat related trauma.

METHODS AND ANALYSIS

ADVANCE is a prospective cohort study. 1200 Afghanistan-deployed male UK military personnel and veterans will be recruited and will be studied at 0, 3, 6, 10, 15 and 20 years. Half are personnel who sustained combat trauma; a comparison group of the same size has been frequency matched based on deployment to Afghanistan, age, sex, service, rank and role. Participants undergo a series of physical health tests and questionnaires through which information is collected on cardiovascular disease (CVD), CVD risk factors, musculoskeletal disease, mental health, functional and social outcomes, quality of life, employment and mortality.

ETHICS AND DISSEMINATION

The ADVANCE Study has approval from the Ministry of Defence Research Ethics Committee (protocol no:357/PPE/12) agreed 15 January 2013. Its results will be disseminated through manuscripts in clinical/academic journals and presentations at professional conferences, and through participant and stakeholder communications.

TRIAL REGISTRATION NUMBER

The ADVANCE Study is registered at ISRCTN ID: ISRCTN57285353.

The Stanford Hall consensus statement for post-COVID-19 rehabilitation

The highly infectious and pathogenic novel coronavirus (CoV), severe acute respiratory syndrome (SARS)-CoV-2, has emerged causing a global pandemic. Although COVID-19 predominantly affects the respiratory system, evidence indicates a multisystem disease which is frequently severe and often results in death. Long-term sequelae of COVID-19 are unknown, but evidence from previous CoV outbreaks demonstrates impaired pulmonary and physical function, reduced quality of life and emotional distress. Many COVID-19 survivors who require critical care may develop psychological, physical and cognitive impairments. There is a clear need for guidance on the rehabilitation of COVID-19 survivors. This consensus statement was developed by an expert panel in the fields of rehabilitation, sport and exercise medicine (SEM), rheumatology, psychiatry, general practice, psychology and specialist pain, working at the Defence Medical Rehabilitation Centre, Stanford Hall, UK. Seven teams appraised evidence for the following domains relating to COVID-19 rehabilitation requirements: pulmonary, cardiac, SEM, psychological, musculoskeletal, neurorehabilitation and general medical. A chair combined recommendations generated within teams. A writing committee prepared the consensus statement in accordance with the appraisal of guidelines research and evaluation criteria, grading all recommendations with levels of evidence. Authors scored their level of agreement with each recommendation on a scale of 0-10. Substantial agreement (range 7.5-10) was reached for 36 recommendations following a chaired agreement meeting that was attended by all authors. This consensus statement provides an overarching framework assimilating evidence and likely requirements of multidisciplinary rehabilitation post COVID-19 illness, for a target population of active individuals, including military personnel and athletes.

Non-battle injury among repatriated UK armed forces since cessation of combat operations: a prospective observational study

Aim

To describe the mechanisms, burden of injury, inpatient management and rehabilitation requirements of wounded military personnel at the UK Role 4 (R4) facility within the first 12 months following cessation of combat operations in Afghanistan.

Methods

All aeromedical evacuations were recorded prospectively between October 2014 and October 2015. Demographic, logistical and clinical data were derived manually from referring medical unit and patient movement requests in addition to host nation and R4 medical records.

Results

Ninety-five patients were repatriated to R4 following traumatic injury: 98.9% (n=94) were male, and median age was 27 years (IQR 25–36 years). The most common mechanisms of injury (MOIs) were sports 26.3% (n=25), falls <2 m 11.6% (n=11) and road traffic collisions 9.8% (n=9). The most common anatomical regions of injury were isolated lower limb 24.1% (n=22), isolated hand 20.0% (n=19) and polytrauma 14.7% (n=14). Median Injury Severity Score was 4 (IQR 4–9), mean 8 (range 1–41). Eleven patients (11.6%) were discharged to rehabilitation units, of whom 7 (63.6%) required neurorehabilitation.

Conclusion

Although service personnel sustain civilian-type injuries, the specific rehabilitation goals and shift in the acute rehabilitation requirements for military personnel must be considered in the absence of enduring combat operations. It is notable that permanent medical downgrading secondary to trauma still occurs outside of warfare. The colocation of civilian major trauma services and R4 has ensured a mutually beneficial partnership that contributes to institutional memory and improves the coordination of patient pathways. The importance of relevant resource allocation, training, support and logistical considerations remain, even during the current scale of military activity overseas.

The Mayo Portland Adaptability Inventory-4 outcome measure is superior to UK FIM+FAM in a British military population

OBJECTIVE

The aim of this study was to identify the most appropriate rehabilitation outcome measure for use in a young adult population with acquired brain injury.

METHODS

A 2-year prospective study of patients admitted to a UK military neuro-rehabilitation unit with acquired brain injury to compare the appropriateness of the Functional Independence Measure/Functional Assessment Measure (FIM+FAM) vs the Mayo-Portland Adaptability Inventory Version 4 (MPAI-4) in assessing outcomes. Patients were assessed at admission, discharge and at 4-month follow-up using FIM+FAM and MPAI-4.

RESULTS

The FIM+FAM total motor score showed a marked ceiling affect, 42% of patients scored the maximum on admission rising to 80% at discharge. The MPAI-4 did not show significant ceiling effects. The other sub-scales of FIM+FAM and MPAI-4 were generally comparable, no more than 17% achieved ceiling at follow-up.

CONCLUSIONS

This is the first comparative study of FIM+FAM and MPAI-4 in a young adult military population following acquired brain injury. All patients showed improvements in both outcome measures following intensive inpatient rehabilitation. However, the MPAI-4 did not show ceiling effects in motor scores. This measure was, therefore, found to be more appropriate in the cohort.

Access to post-discharge inpatient care after lower limb trauma

BACKGROUND

Most hospitals in the United States are required to provide emergency care to all patients, regardless of insurance status. However, uninsured patients might be unable to access non-acute services, such as post-discharge inpatient care (PDIC). This could result in prolonged acute hospitalization. We tested the hypothesis that insurance status would be independently associated with both PDIC and length of stay (LOS).

METHODS

An observational study was undertaken using the California State Inpatient Database (2007-2011), which captures 98% of patients admitted to hospital in California. All patients with a diagnosis of orthopedic lower limb trauma were identified using International Classification of Diseases, 9th Revision, Clinical Modification codes 820-828. Multivariable logistic and generalized linear regression models were used to adjust odds of PDIC and LOS for patient and hospital characteristics.

RESULTS

There were 278,573 patients with orthopedic lower limb injuries, 160,828 (57.7%) of which received PDIC. Uninsured patients had lower odds of PDIC (adjusted odds ratio 0.20, 95% confidence interval 0.17-0.24) and significantly longer hospital LOS (predicted mean difference 1.06 [95% confidence interval 0.78-1.34] d) than those with private insurance.

CONCLUSIONS

Lack of health insurance is associated with reduced access to PDIC and prolonged hospital LOS. This potential barrier to hospital discharge could reduce the number of trauma beds available for acutely injured patients.
