Rehabilitation and COVID-19: a rapid living systematic review by Cochrane Rehabilitation Field updated as of December 31st, 2020 and synthesis of the scientific literature of 2020

Update to the PRISMA guidelines for network meta-analyses and scoping reviews and development of guidelines for rapid reviews: a scoping review protocol

OBJECTIVE

The objective of this scoping review is to develop a list of items for potential inclusion in the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) reporting guidelines for network meta-analysis (NMA), scoping reviews (ScRs), and rapid reviews (RRs).

INTRODUCTION

The PRISMA extensions for NMA and ScRs were published in 2015 and 2018. However, since then, their methodologies and innovations, including automation, have evolved. There is no reporting guideline for RRs. In 2020, an updated PRISMA statement was published, reflecting advances in the conduct and reporting of systematic reviews. These advances are not yet incorporated into these PRISMA extensions. We will update our previous methods for scoping reviews to inform the update of PRISMA-NMA and PRISMA-ScR as well as the development of the PRISMA-RR reporting guidelines.

INCLUSION CRITERIA

This review will include any study design evaluating the completeness of reporting, offering reporting guidance, or assessing methods relevant to NMA, ScRs, or RRs. Editorial guidelines and tutorials that describe items related to reporting completeness will also be eligible.

METHODS

We will follow the JBI guidance for scoping reviews. For each PRISMA extension, we will i) search multiple electronic databases from inception to present, ii) search for unpublished studies, and iii) scan the reference lists of included studies. There will be no language limitations. Screening and data extraction will be conducted by 2 researchers independently. A third researcher will resolve discrepancies. We will conduct frequency analyses of the identified items. The final list of items will be considered for potential inclusion in the relevant PRISMA reporting guidelines.

Effect of a 4-Week Telerehabilitation Program for People With Post-COVID Syndrome on Physical Function and Symptoms: Protocol for a Randomized Controlled Trial

OBJECTIVE

COVID-19 has led to significant morbidity and mortality globally. Post-COVID sequelae can persist beyond the acute and subacute phases of infection, often termed post-COVID syndrome (PCS). There is limited evidence on the appropriate rehabilitation for people with PCS. The aim of this study is to evaluate the effect on exercise capacity, symptoms, cognition, anxiety, depression, health-related quality of life, and fatigue of a 4-week, twice-weekly supervised pulmonary telerehabilitation program compared with usual medical care for people with PCS with persistent respiratory symptoms.

METHODS

The study will be a multi-site randomized controlled trial with assessor blinding. Participants with confirmed previous COVID-19 infection and persistent respiratory symptoms who attend a post-COVID respiratory clinic will be randomized 1:1 to either an intervention group of 4 weeks, twice-weekly pulmonary telerehabilitation or a control group of usual medical care. Participants in the control group will be invited to cross-over into the intervention group after the week 4 assessment. Primary outcome: exercise capacity measured by the 1-minute sit-to-stand test. Secondary outcomes: 5 repetition sit-to-stand test; Montreal Cognitive Assessment; COVID-19 Yorkshire Rehabilitation Scale; Chronic Obstructive Pulmonary Disease Assessment Test; 36-Item Short-Form Health Survey; Hospital Anxiety and Depression Scale; Fatigue Severity Scale; and the Kessler Psychological Distress Scale. Outcomes will be collected at baseline, after 4-weeks intervention or control period, after intervention in the cross-over group, and at 12-month follow-up.

IMPACT

Research into effective rehabilitation programs is crucial given the substantial morbidity associated with PCS and the lack of long-term data for COVID-19 recovery. A short-duration pulmonary telerehabilitation program, if effective compared with usual care, could inform practice guidelines and direct future clinical trials for the benefit of individuals with persistent respiratory symptoms post-COVID.

Impact of COVID-19 critical illness on functional status, fatigue symptoms, and health-related quality of life one-year after hospital discharge: a systematic review and meta-analysis

PURPOSE

To estimate the prevalence and severity of impairments in functional status, fatigue, and health-related quality of life (HRQoL) among critical COVID-19 survivors one-year after hospital discharge.

METHODS

A systematic review was conducted following PRISMA statement and registered in PROSPERO (CRD42021258356), with searches in eight databases. Observational studies were selected. The prevalence meta-analysis of abnormalities was performed using random-effects models. Risk of bias was evaluated using the National Heart, Lung, and Blood Institute tool.

RESULTS

Twenty studies were included, with data collected between 12 and 13.5 months after hospital discharge and a total of 1828 participants. Of these, 71% were men, and 77.7% were intubated in the intensive care unit (ICU). Impairments and sequelae were identified in varying prevalence and degrees, with greater impact on functional capacity and physical components of fatigue and HRQoL. The prevalence of abnormalities of 32.3% [95% CI 23.9; 41.9] found in the meta-analysis is substantially high. Most studies were classified as having fair and poor quality.

CONCLUSION

Critical COVID-19 survivors experience impairments in functional status, fatigue, and HRQoL to varying degrees one-year after hospital discharge, particularly among patients who stayed in the ICU and on MV for a prolonged period.

Prevalence of Unmet Rehabilitation Needs Among Canadians Living With Long-term Conditions or Disabilities During the First Wave of the COVID-19 Pandemic

OBJECTIVE

We aimed to describe the prevalence of unmet rehabilitation needs among a sample of Canadians living with long-term conditions or disabilities during the first wave of the COVID-19 pandemic.

DESIGN

Cross-sectional survey.

SETTING

Individuals residing in Canada during the first wave of the COVID-19 pandemic.

PARTICIPANTS

Eligible participants were Canadians living with long-term conditions or disabilities, 15 years or older living in 1 of the 10 provinces or 3 territories (n=13,487).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURE

We defined unmet rehabilitation needs as those who reported needing rehabilitation (ie, physiotherapy/massage therapy/chiropractic, speech, or occupational therapy, counseling services, support groups) but did not receive it because of the COVID-19 pandemic. We calculated the national, age, gender, and province/territory-specific prevalence and 95% confidence interval of unmet rehabilitation needs.

RESULTS

During the first wave of the pandemic, the prevalence of unmet rehabilitation needs among Canadians with long-term conditions or disabilities was 49.3% (95% confidence interval [CI]; 48.3, 50.3]). The age-specific prevalence was higher among individuals 15-49 years old (55.6%; 95% CI [54.2, 57.1]) than those 50 years and older (46.0%; 95% CI [44.5, 47.4]). Females (53.7%; 95% CI [52.6, 54.9]) had higher unmet needs than males (44.1%; 95% CI [42.3, 45.9]). Unmet rehabilitation needs varied across provinces and territories.

CONCLUSIONS

In this sample, almost 50% of Canadians living with long-term conditions or disabilities had unmet rehabilitation needs during the first wave of the COVID-19 pandemic. This suggests that a significant gap between the needs for and delivery of rehabilitation care existed during the early phase of the pandemic.

Efficacy of rehabilitation treatments in improving functioning in patients with fibromyalgia: A systematic review and meta-analysis of randomized controlled trials

BACKGROUND

Fibromyalgia is a debilitating condition marked by persistent pain and reduced functionality. Various therapeutic methods have been suggested to alleviate symptoms in individuals with fibromyalgia, yet the impact of diverse rehabilitation strategies remains unclear.

OBJECTIVE

This systematic review and meta-analysis aimed at assessing the efficacy of rehabilitation interventions in improving functioning in fibromyalgia patients.

METHODS

We conducted a comprehensive literature search of multiple international databases (PubMed, Scopus, and Web of Science) from their inception until November 22nd, 2023. We identified 23 randomized controlled trials (RCTs) assessing multiple rehabilitation strategies. The primary outcome was the Fibromyalgia Impact Questionnaire (FIQ). Study quality was assessed using the Cochrane Risk-of-Bias Tool for Randomized Trials (RoB 2). The study protocol was registered in PROSPERO (CRD42020197666).

RESULTS

Our meta-analysis rehabilitation interventions significantly reduce FIQ scores (MD =-11.74, 95% CI: -16.88 to -6.59, p< 0.0001). Notably, the subgroup analysis showed that different rehabilitation modalities seem to induce different therapeutic responses.

CONCLUSIONS

Rehabilitation strategies hold promise in addressing the functional impairments and improving the overall well-being of individuals with fibromyalgia. The study underscores the need for further research to determine the optimal rehabilitation approach and its potential impact on the multilevel disability characterizing patients with fibromyalgia.

Rehabilitation and COVID-19: systematic review by Cochrane Rehabilitation

INTRODUCTION

Until the last update in February 2022, the Cochrane Rehabilitation COVID-19 Evidence-based Response (REH-COVER) action identified an increasing volume of evidence for the rehabilitation management of COVID-19. Therefore, our aim was to identify the best available evidence on the effectiveness of interventions for rehabilitation for COVID-19-related limitations of functioning of rehabilitation interest in adults with COVID-19 or post COVID-19 condition (PCC).

EVIDENCE ACQUISITION

We ran the searches on February 17th, 2023, in the following databases: PubMed, EMBASE, CENTRAL, CINHAL, and the Cochrane COVID-19 Study Register, applying a publication date restriction to retrieve only papers published in 2022. To retrieve papers published before 2022, we screened the reference lists of previous publications included in the REH-COVER action, covering papers from early 2020 to the end of 2022. This current review includes only randomised controlled trials and concludes the rapid living systematic reviews of the Cochrane Rehabilitation REH-COVER action. The risk of bias and certainty of evidence were evaluated in all studies using the Cochrane Risk of Bias tool and GRADE, respectively. We conducted a narrative synthesis of the evidence. PROSPERO registration number: CRD42022374244.

EVIDENCE SYNTHESIS

After duplicate removal, we identified 18,950 individual records and 53 RCTs met the inclusion criteria. Our findings suggest that the effect of breathing and strengthening exercise programs on dyspnea and physical exercise capacity compared to no treatment in non-severe COVID-19 patients is uncertain. Multicomponent telerehabilitation may slightly increase physical exercise capacity compared to educational intervention in adults with PCC. There is, however, uncertainty about its effect on lung function and physical exercise capacity when compared to no treatment. Finally, the effect of inspiratory muscle training on maximal inspiratory pressure compared to no treatment in adults with PCC is uncertain.

CONCLUSIONS

Interventions that are part of comprehensive pulmonary rehabilitation approaches may benefit dyspnea and exercise tolerance in adults with COVID-19 and PCC. The available evidence has several methodological limitations that limit the certainty of evidence and the clinical relevance of findings. Therefore, we cannot provide robust suggestions for practice. While high-quality RCTs are being conducted, clinicians should consider using high-quality evidence from other pulmonary conditions to rehabilitate patients with COVID-19 or PCC using context-specific interventions.

Evidence-based position paper on physical and rehabilitation medicine professional practice for persons with COVID-19, including post COVID-19 condition: the European PRM position (UEMS PRM Section)

Although multiple factors still pose challenges to inpatient/outpatient rehabilitation for survivors of COVID-19, rehabilitation plays a key role for this patient population. This study aimed to improve Physical and Rehabilitation Medicine (PRM) physician's professional practice for persons with COVID-19-related functioning limitations, to promote functional recovery and reduce activity limitations and/or participation restrictions. A systematic review of the scientific literature was performed from December 2019 to August 2022, followed by production of recommendations through 5 Delphi rounds, by consensus among the delegates of all European countries represented in the Union of European Medical Specialists PRM Section. The systematic literature review is reported together with thirty-two recommendations resulting from the Delphi procedure. The PRM physician's role for persons with COVID-19-related limitations of functioning is to develop, foster, and monitor the implementation of an individual rehabilitation project tailored to the patient's age, previous medical and functional status, current comorbidities and complications, activity limitations and participation restrictions and personal and environmental factors. This is done by applying the concept of a multi-specialty integrated service model with multi-professional/interdisciplinary teams, providing care at all stages of COVID-19 illness. This evidence-based position paper represents the official position of the European Union through the UEMS PRM Section.

Multidisciplinary inpatient rehabilitation for older adults with COVID-19: a systematic review and meta-analysis of clinical and process outcomes

BACKGROUND

Older adults are at increased risk for disease severity and poorer prognosis following COVID-19 infection. The aim of this systematic review and meta-analysis is to explore the impact of multidisciplinary rehabilitation in the acute or post-acute hospital setting for older adults with COVID-19.

METHODS

The Cochrane library, EMBASE, Cinahl and Medline (via EBSCO), PubMed, and Web of Science were systematically searched in June 2022 and a repeat search was completed in March 2023. Screening, data extraction and quality appraisal were conducted independently by two reviewers. Studies reporting outcomes for older adults following multidisciplinary rehabilitation (provided by two or more Health and Social Care Professionals) were included. Both observational and experimental study designs were included. The primary outcome was functional ability. Secondary outcomes included discharge disposition, acute hospital and rehabilitation unit length of stay, mortality, primary and secondary healthcare utilisation, and long-term effects of COVID-19.

RESULTS

Twelve studies met the inclusion criteria, comprising a total of 570 older adults. Where reported, older adults stayed in the acute hospital for a mean of 18 days (95%CI, 13.35- 23.13 days) and in rehabilitation units for 19 days (95%CI, 15.88-21.79 days). There was a significant improvement in functional ability among older adults with COVID-19 who received multidisciplinary rehabilitation (REM, SMD = 1.46, 95% CI 0.94 to 1.98). The proportion of older adults who were discharged directly home following rehabilitation ranged from 62 to 97%. Two studies reported a 2% inpatient mortality rate of older persons during rehabilitative care. No study followed up patients after the point of discharge and no study reported on long term effects of COVID-19.

CONCLUSIONS

Multidisciplinary rehabilitation may result in improved functional outcomes on discharge from rehabilitation units/centres for older adults with COVID-19. Findings also highlight the need for further research into the long-term effect of rehabilitation for older adults following COVID-19. Future research should comprehensively describe multidisciplinary rehabilitation in terms of disciplines involved and the intervention provided.

[Evidence map on post-acute COVID-19 sequelae and rehabilitation: Update as of July 2022Mapa de evidencia sobre las secuelas y la rehabilitación tras la COVID-19 aguda: versión actualizada en julio del 2022]

Objective

To update the evidence map on the effects of interventions for post-acute COVID-19 rehabilitation.

Method

The search scope was defined according to the population (patients with symptomatic COVID-19 and post-acute COVID sequelae), the context (interventions for rehabilitation), and the type of study (systematic reviews, rapid reviews, scoping reviews or overviews of reviews). Following a search in PubMed and the Virtual Health Library, two independent authors selected the articles for review. The map was updated on July 27, 2022, using the same procedures employed in the initial review.

Results

The initial evidence map included 22 studies (four systematic reviews, four rapid reviews, four reviews of case reports, one scoping review, and nine systematic review protocols). In the present update, an additional 10 studies were included. The analysis revealed four groups of interventions (multimodal, therapeutic, complementary, and pharmacological) and seven groups of outcomes (pathological conditions, diseases/respiratory disorders, pain, physiological and metabolic markers, mental health/quality of life, sensory function, and mortality), totaling 166 associations between interventions and outcomes. The highest number of associations was observed for complementary therapies (n = 94). Among the outcomes, the highest number of associations was observed for physiological and metabolic markers, pathological conditions, and mental health/quality of life (44, 41, and 35 associations respectively).

Conclusions

The map update involved the analysis of 69 associations, most notably exercise (isolated, multicomponent, or multimodal intervention), with 23 positive and four potentially positive effects) and pharmacologic and complementary therapies for sensorial functions (15 associations). The high number of systematic review protocols indicates that the literature is still incipient.

The predictive role of fatigue and neuropsychological components on functional outcomes in COVID-19 after a multidisciplinary rehabilitation program

OBJECTIVE

To verify the impact of altered cognitive functioning and higher levels of mental fatigue, both reported after coronavirus disease 2019 (COVID-19), on rehabilitation treatment outcomes.

METHODS

In this real-practice retrospective pre-post intervention cohort study, cognitive functioning, measured through standardized neuropsychological measures, and individual levels of fatigue, depression and anxiety symptoms, were evaluated at admission to a rehabilitation program in individuals who had been hospitalized for COVID-19. The rehabilitation program effectiveness was measured through the Functional Independence Measure.

RESULTS

Among the patient sample (n = 66), 87.88% reported experiencing high levels of fatigue at admission, while 16.67% reported depressive symptoms, and 22.73% reported anxiety symptoms. After rehabilitation, the sample displayed a significant decrease in the level of disability, in both the motor and cognitive subscales. Neuropsychological and psychological functioning did not play a predictive role. The 45 patients who received mechanical ventilation during intensive care, representing 68.18% of the sample, benefited more from rehabilitation treatment.

CONCLUSIONS

The results support the importance of an early rehabilitation program after COVID-19 infection, independent of the initial neuropsychological and psychological functioning. Respiratory assistance may represent a crucial factor for short-term neuropsychological disease after-effects. Future studies on the long-term neuropsychological effect of COVID-19 infection on individual levels of disability are necessary.

Psychological and Cognitive Functioning Among Patients Receiving Outpatient Rehabilitation for Post-COVID Sequelae: An Observational Study

OBJECTIVES

To describe the characteristics of individuals receiving outpatient rehabilitation for post-acute sequelae of SARS-CoV-2 infection (PASC). Further, to examine factors associated with variation in their psychological and cognitive functioning and health-related quality of life.

DESIGN

Observational study.

SETTING

Outpatient COVID-19 recovery clinic at a large, tertiary, urban health system in the US.

PARTICIPANTS

COVID-19 survivors with persistent sequelae (N=324).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Multivariable logistic and linear regression models were used to examine factors associated with COVID survivors' experience of severe anxiety, severe depression, post-traumatic stress disorder (PTSD), cognitive impairment, and self-reported health-related quality of life.

RESULTS

About 38% of survivors seeking care for their persistent COVID symptoms suffered from severe anxiety, 31.8% from severe depression, 43% experiencing moderate to severe PTSD symptomology, and 17.5% had cognitive impairment. Their health-related quality of life was substantially lower than that of the general population (-26%) and of persons with other chronic conditions. Poor and African American/Black individuals experienced worse psychological and cognitive sequelae after COVID19 infection, even after controlling for age, sex, initial severity of the acute infection, and time since diagnosis.

CONCLUSIONS

Evidence of consistent disparities in outcomes by the patients' race and socioeconomic status, even among those with access to post-acute COVID rehabilitation care, are concerning and have significant implications for PASC policy and program development.

Validity, inter-rater reliability, and feasibility of the Chelsea Physical Assessment Tool for assessing physical function in post-acute COVID-19 patients: A cross-sectional study

BACKGROUND

Various tools have been created to measure physical function during intensive care unit (ICU) stay and after ICU discharge, but those have not been validated in coronavirus 2019 (COVID-19) patients. There is a need for a reliable, valid and feasible tool to define the rehabilitation needs of post-ICU COVID-19 patients entering the acute wards and then rehabilitation clinics.

OBJECTIVE

This study aims to investigate the validity, inter-rater reliability and feasibility of Chelsea Physical Assessment Tool (CPAx) in assessing the functional status of COVID-19 patients after discharge from the ICU.

METHODS

Demographic and clinical characteristics of the patients were recorded. Patients were evaluated using the modified Medical Research Council (MRC) dyspnea scale, Functional Oral Intake Scale, Glasgow Coma Scale, CPAx, Barthel Index, Katz Index and MRC sum score, measurements of grip strength obtained by dynamometer, the 5 time sit-to-stand test and 30 seconds and sit-to-stand test. CPAx and the other functional assessment tools were administered to 16 patients within 48 hours following ICU discharge. For inter-rater reliability, another physiatrist independently re-assessed the patients. MRC sum score, Barthel and Katz indexes were used to assess construct validity of CPAx. The discriminative validity of CPAx was determined by its ability to differentiate between patients with and without ICU acquired muscle weakness based on MRC sum score. The intra-class correlation coefficients (ICC) were calculated to determine inter-rater reliability for total scores of the functional assessment tools. Cohen's Kappa (κ) coefficient and weighed Kappa (κw) were calculated to determine inter-rater reliability of individual CPAx items. Ceiling and flooring effects were calculated by percentage frequency of lowest or highest possible score achieved. The number and percentages of the patients who were able to complete each tool were calculated to assess feasibility.

RESULTS

The CPAx score was strongly correlated with MRC sum score (rho: 0.83), Barthel Index (rho: 0.87) and Katz Index (rho: 0.89) (p< 0.001) showing construct validity. Area under the ROC curve demonstrated that cut off score for CPAx was ⩽ 12 to discriminate patients with MRC sum score < 48, with a sensitivity and a specificity of 100% and 63%, respectively (AUC = 0.859, p< 0.001). ICC was high for CPAx, MRC sum score, Barthel and Katz indexes, Glasgow Coma Scale, and hand grip strength measurement, with the highest value observed for CPAx (ICC, 0.96; 95% confidence interval (CI), 0.71-0.98). κ and κw analysis showed good to excellent inter-rater reliability for individual CPAx items. No floor or ceiling effect was observed at CPAx while floor effect was observed at Barthel Index scores (25%) and Katz Index scores (37.5%). All patients could be evaluated using CPAx while less were physically able to complete the 5 time sit-to-stand, 30 seconds sit-to-stand tests (n= 4) and MRC sum score (n= 14).

CONCLUSION

CPAx is a valid, reliable, and feasible tool to assess the physical functional state in COVID-19 patients following discharge from the ICU.

Cochrane "evidence relevant to" rehabilitation of people with post COVID-19 condition. What it is and how it has been mapped to inform the development of the World Health Organization recommendations

Cochrane Rehabilitation developed a series of actions to provide the global rehabilitation community with the best available evidence to respond to the COVID-19 pandemic. These initiatives constituted the REH-COVER (Rehabilitation COVID-19 evidence-based response) action. In March 2020, the first initiative started in agreement with the European Journal of Physical and Rehabilitation Medicine (EJPRM): the rapid systematic review of all papers relevant to COVID-19 rehabilitation to inform rehabilitation health professionals rapidly. Currently, we are facing the long-term consequences of COVID-19, initially called "long Covid" and now named post COVID-19 condition (PCC), which led to the request by the WHO Rehabilitation Programme for evidence synthesis to support the development of specific recommendations. Cochrane Rehabilitation provided the best available evidence from the REH-COVER rapid living systematic review results, a systematic scoping review on the models of care and a summary of "evidence relevant to" the rehabilitation for adults with PCC. Based on this evidence, expert groups developed the 16 recommendations for the rehabilitation of adults with PCC recently published in Chapter 24 of the WHO "Clinical management of COVID-19 living guideline." This paper aims to introduce the Special Section of EJPRM reporting the work performed by Cochrane Rehabilitation to produce a summary of the existing "evidence relevant to" the rehabilitation of adults with PCC. The paper reports the methodology (overview of systematic reviews with mapping) and introduces the concept of "evidence relevant to" rehabilitation.

Cardiopulmonary disease as sequelae of long-term COVID-19: Current perspectives and challenges

COVID-19 infection primarily targets the lungs, which in severe cases progresses to cytokine storm, acute respiratory distress syndrome, multiorgan dysfunction, and shock. Survivors are now presenting evidence of cardiopulmonary sequelae such as persistent right ventricular dysfunction, chronic thrombosis, lung fibrosis, and pulmonary hypertension. This review will summarize the current knowledge on long-term cardiopulmonary sequelae of COVID-19 and provide a framework for approaching the diagnosis and management of these entities. We will also identify research priorities to address areas of uncertainty and improve the quality of care provided to these patients.

Osteosarcopenia in Patients with Chronic Obstructive Pulmonary Diseases: Which Pathophysiologic Implications for Rehabilitation?

Chronic obstructive pulmonary disease (COPD) is a burdensome condition affecting a growing number of people worldwide, frequently related to major comorbidities and functional impairment. In these patients, several factors might have a role in promoting both bone and muscle loss, including systemic inflammation, corticosteroid therapies, sedentary behaviours, deconditioning, malnutrition, smoking habits, and alcohol consumption. On the other hand, bone and muscle tissues share several linkages from functional, embryological, and biochemical points of view. Osteosarcopenia has been recently defined by the coexistence of osteoporosis and sarcopenia, but the precise mechanisms underpinning osteosarcopenia in patients with COPD are still unknown. In this scenario, a deeper understanding of the molecular basis of osteosarcopenia might guide clinicians in a personalized approach integrating skeletal muscle health with the pulmonary rehabilitation framework in COPD. Taken together, our results summarized the currently available evidence about the multilevel interactions between osteosarcopenia and COPD to pave the way for a comprehensive approach targeting the most common risk factors of these pathological conditions. Further studies are needed to clarify the role of modern clinical strategies and telemedicine solutions to optimize healthcare delivery in patients with COPD, including osteopenia, osteoporosis, and sarcopenia screening in these subjects.

Risk factors and preventive interventions for post Covid-19 condition: systematic review

This systematic review examined pre-existing and clinical risk factors for post Covid-19 condition (≥12 weeks after onset), and interventions during acute and post-acute phases of illness that could potentially prevent post Covid-19 condition. The review focuses on studies collecting data during the early phases of the pandemic and prior to the emergence of variants of concern and widespread vaccination. We searched bibliographic databases and grey literature. Two investigators independently reviewed abstracts and full-text articles, and data extraction and risk of bias assessments were verified. Meta-analysis was performed when suitable and we assessed the certainty of evidence using GRADE. We included 31 studies. We found small-to-moderate associations (e.g. adjusted odds ratios 1.5 to <2.0) between female sex and higher non-recovery, fatigue, and dyspnea (moderate certainty). Severe or critical acute-phase Covid-19 severity (versus not) has probably (moderate certainty) a large association (adjusted ratio ≥2.0) with increased cognitive impairment, a small-to-moderate association with more non-recovery, and a little-to-no association with dyspnea. There may be (low certainty) large associations between hospitalization and increased non-recovery, increased dyspnea, and reduced return to work. Other outcomes had low certainty of small-to-moderate or little-to-no association or very low certainty. Several potential preventive interventions were examined, but effects are very uncertain. Guidelines in relation to surveillance, screening, and other services such as access to sickness and disability benefits, might need to focus on females and those with previously severe Covid-19 illness. Continuous assessment of emerging evidence, especially on whether different variants and vaccination impact outcomes, will be important. PROSPERO registration: CRD42021270354.

The prevention of falls in patients with Parkinson's disease with in-home monitoring using a wearable system: a pilot study protocol

BACKGROUND

Parkinson's disease (PD) is a chronic, progressive neurodegenerative condition that gradually worsens motor function and leads to postural instability and, eventually, falls. Several factors may influence the frequency of future falls, such as slowness, freezing of gait, loss of balance, and mobility problems, cognitive impairments, and the number of previous falls. The TED bracelet is an advanced technological wearable device able to predict falls.

AIMS

This principal aim is to investigate the feasibility of a full-scale research project that uses the TED bracelet to identify whether individuals with PD are at risk of falling.

METHODS

This study will involve a pilot prospective observational study design; the subjects will include 26 patients suffering from mild PD and 26 others with no PD and no gait problems. Data will be collected from the TED bracelet and then compared to a paper-based fall diary. The enrolled participants will have a scheduled outpatient evaluation to collect both clinical and instrumental data as well as biological samples.

DISCUSSION

This pilot study could then be implemented in a larger form to further evaluate the effectiveness of the TED device. Finally, it will help further develop gait monitoring systems for people with Parkinson's disease and other neurodegenerative diseases that can affect physical function and mobility, such as dementia and Alzheimer's.

CONCLUSIONS

Preventing falls and their complications could lead to major advancements in the quality of home care for patients with PD, which would significantly impact the quality of life of both these patients and their caregivers.

Functioning issues in inpatients affected by COVID-19-related moderate pulmonary impairment: a real-practice observational study

OBJECTIVE

To investigate the correlations between clinical, functional, and radiological outcomes in inpatients with coronavirus disease 2019 (COVID-19).

METHODS

In this observational study, we recruited inpatients affected by moderate COVID-19 disease. The clinical evaluation comprised the Cumulative Illness Rating Scale (CIRS), numerical rating scale (NRS), modified Rankin scale (mRS), and the modified Borg dyspnea scale (mBDS). Respiratory involvement was assessed with computed tomography (CT) and graded with a CT-severity score (CT-SS). We retrospectively assessed functioning using the International Classification of Functioning, Disability and Health (ICF) codes of the Clinical Functioning Information Tool (ClinFIT) COVID-19 in the acute phase. Correlation analysis was performed 1) between clinical, instrumental, and functional parameters and 2) between ICF categories.

RESULTS

The data showed statistically significant moderate correlations between CT-SS and the following categories: b152 "emotional functions" and b440 "respiratory functions".

CONCLUSION

This is the first study to use the ICF framework in people with a moderate form of COVID-19 in the acute phase. Considering the correlations between some ICF categories and radiological findings, our results support the use of the ClinFIT COVID-19 for a comprehensive assessment of COVID-19 patients.

Telerehabilitation proposal of mind-body technique for physical and psychological outcomes in patients with fibromyalgia

Fibromyalgia (FM) syndrome is characterized by the close correlation of chronic widespread pain and other non-pain related symptoms. Aim of this study was to investigate whether telerehabilitation that provides physical and psychological support services of the mind-body techniques can affect the clinical profile and pain relief of FM patients. The study included twenty-eight female FM patients, mean aged 56.61 ± 8.56 years. All patients underwent a rehabilitation treatment (8 sessions, 1/week, 1 h/each) through Zoom platform, with the following principles of rehabilitation treatment: Anchoring to a positive emotion; listen and perceive your “own” body; conscious breathing; improve interoceptive awareness; relax. All patients then underwent clinical assessment of the physical distress and fear of movement for the Numeric Rating Scale (NRS); the Fatigue Assessment Scale (FAS); the Fear Avoidance Belief Questionnaire (FABQ); with measures of physical and mental disability for the Fibromyalgia Impact Questionnaire (FIQ); the 12-Items Short Form Survey; the Resilience Scale for Adults and the Coping Strategies Questionnaire-Revised. The evaluations were performed at T0 (baseline), T1 (after 8 weeks of treatment), and T2 (after 1 month of follow-up). The main finding was that telerehabilitation reduced physical and mental distress, fear, and disability (p < 0.001). Resilience and coping ability were less affected by the rehabilitative treatment. Our attempt of mind-body technique telerehabilitation has shown good results in the improvement of painful symptoms and quality of life for the FM patients but showed fewer positive impacts for the resilience and coping abilities aspects.

The Use of Modern Technologies in Post-COVID-19 Cardiopulmonary Rehabilitation

Managing cardiopulmonary rehabilitation in patients with COVID-19 remains a global challenge due to the facets of this virus. The technologies used in the rehabilitation of post-COVID-19 patients fail to keep pace with the global epidemiological developments. The purpose of this article is to review the medical technologies used in post-COVID-19 cardiopulmonary rehabilitation and the innovations that have allowed us to adapt and care for our patients. The pandemic highlighted the need for seismic changes in diagnostic and rehabilitation paradigms. We discuss advances in telemedicine and telemedicine-based rehabilitation, remote patient monitoring and emerging technologies used in cardiopulmonary rehabilitation. The rapid adoption of modern technologies in the practice of post-COVID-19 cardiopulmonary rehabilitation is promising and can improve patients’ access to complex rehabilitation programs with outstanding results.

ESCMID rapid guidelines for assessment and management of long COVID

SCOPE

The aim of these guidelines is to provide evidence-based recommendations for the assessment and management of individuals with persistent symptoms after acute COVID-19 infection and to provide a definition for this entity, termed 'long COVID'.

METHODS

We performed a search of the literature on studies addressing epidemiology, symptoms, assessment, and treatment of long COVID. The recommendations were grouped by these headings and by organ systems for assessment and treatment. An expert opinion definition of long COVID is provided. Symptoms were reviewed by a search of the available literature. For assessment recommendations, we aimed to perform a diagnostic meta-analysis, but no studies provided relevant results. For treatment recommendations we performed a systematic review of the literature in accordance with the PRISMA statement. We aimed to evaluate patient-related outcomes, including quality of life, return to baseline physical activity, and return to work. Quality assessment of studies included in the systematic review is provided according to study design.

RECOMMENDATIONS

Evidence was insufficient to provide any recommendation other than conditional guidance. The panel recommends considering routine blood tests, chest imaging, and pulmonary functions tests for patients with persistent respiratory symptoms at 3 months. Other tests should be performed mainly to exclude other conditions according to symptoms. For management, no evidence-based recommendations could be provided. Physical and respiratory rehabilitation should be considered. On the basis of limited evidence, the panel suggests designing high-quality prospective clinical studies/trials, including a control group, to further evaluate the assessment and management of individuals with persistent symptoms of COVID-19.

Differences in clinical features and mortality in very old unvaccinated patients (≥ 80 years) hospitalized with COVID-19 during the first and successive waves from the multicenter SEMI-COVID-19 Registry (Spain)

BACKGROUND

Old age is one of the most important risk factors for severe COVID-19. Few studies have analyzed changes in the clinical characteristics and prognosis of COVID-19 among older adults before the availability of vaccines. This work analyzes differences in clinical features and mortality in unvaccinated very old adults during the first and successive COVID-19 waves in Spain.

METHODS

This nationwide, multicenter, retrospective cohort study analyzes unvaccinated patients ≥ 80 years hospitalized for COVID-19 in 150 Spanish hospitals (SEMI-COVID-19 Registry). Patients were classified according to whether they were admitted in the first wave (March 1-June 30, 2020) or successive waves (July 1-December 31, 2020). The endpoint was all-cause in-hospital mortality, expressed as the case fatality rate (CFR).

RESULTS

Of the 21,461 patients hospitalized with COVID-19, 5,953 (27.7%) were ≥ 80 years (mean age [IQR]: 85.6 [82.3-89.2] years). Of them, 4,545 (76.3%) were admitted during the first wave and 1,408 (23.7%) during successive waves. Patients hospitalized in successive waves were older, had a greater Charlson Comorbidity Index and dependency, less cough and fever, and met fewer severity criteria at admission (qSOFA index, PO2/FiO2 ratio, inflammatory parameters). Significant differences were observed in treatments used in the first (greater use of antimalarials, lopinavir, and macrolides) and successive waves (greater use of corticosteroids, tocilizumab and remdesivir). In-hospital complications, especially acute respiratory distress syndrome and pneumonia, were less frequent in patients hospitalized in successive waves, except for heart failure. The CFR was significantly higher in the first wave (44.1% vs. 33.3%; -10.8%; p < 0.001) and was higher among patients ≥ 95 years (54.4% vs. 38.5%; -15.9%; p < 0.001). After adjustments to the model, the probability of death was 33% lower in successive waves (OR: 0.67; 95% CI: 0.57-0.79).

CONCLUSIONS

Mortality declined significantly between the first and successive waves in very old unvaccinated patients hospitalized with COVID-19 in Spain. This decline could be explained by a greater availability of hospital resources and more effective treatments as the pandemic progressed, although other factors such as changes in SARS-CoV-2 virulence cannot be ruled out.

Predictors of Post-Acute Sequelae of COVID-19 Development and Rehabilitation: A Retrospective Study

Objective

To examine the frequency of postacute sequelae of SARS-CoV-2 (PASC) and the factors associated with rehabilitation utilization in a large adult population with PASC.

Design

Retrospective study.

Setting

Midwest hospital health system.

Participants

19,792 patients with COVID-19 from March 10, 2020, to January 17, 2021.

Intervention

Not applicable.

Main Outcome Measures

Descriptive analyses were conducted across the entire cohort along with an adult subgroup analysis. A logistic regression was performed to assess factors associated with PASC development and rehabilitation utilization.

Results

In an analysis of 19,792 patients, the frequency of PASC was 42.8% in the adult population. Patients with PASC compared with those without had a higher utilization of rehabilitation services (8.6% vs 3.8%, P<.001). Risk factors for rehabilitation utilization in patients with PASC included younger age (odds ratio [OR], 0.99; 95% confidence interval [CI], 0.98-1.00; P=.01). In addition to several comorbidities and demographics factors, risk factors for rehabilitation utilization solely in the inpatient population included male sex (OR, 1.24; 95% CI, 1.02-1.50; P=.03) with patients on angiotensin-converting-enzyme inhibitors or angiotensin-receptor blockers 3 months prior to COVID-19 infections having a decreased risk of needing rehabilitation (OR, 0.80; 95% CI, 0.64-0.99; P=.04).

Conclusions

Patients with PASC had higher rehabilitation utilization. We identified several clinical and demographic factors associated with the development of PASC and rehabilitation utilization.

Functional assessment and rehabilitation protocol in acute patients affected by SARS-CoV-2 infection hospitalized in the Intensive Care Unit and in the Medical Care Unit

BACKGROUND

Coronavirus disease (COVID-19) is characterized by different clinical pictures that may require prolonged hospitalization and produce disabilities challenging the recovery of previous independence.

AIM

The aim is to evaluate the impact of an early assisted rehabilitation program on the functional status of an acutely hospitalized population affected by COVID-19.

DESIGN

Single-institution retrospective longitudinal study.

SETTING

Inpatient intensive care units (ICU) and medical care units (MCU).

POPULATION

Acute COVID-19 patients.

METHODS

General information was collected; age-adjusted Charlson Comorbidity Index was used for comorbidities. Duration of hospital stay, the length of stay in ICU and/or MCU, the length of the rehabilitative treatment, and the destination at the discharge were collected. Evaluation was performed when patients were clinically stable (T0), and at hospital discharge (T1); for subjects enrolled in ICU functional status was assessed at the time of transfer to the MCU. Muscle strength of the four limbs was measured with the Medical Research Council (MRC) sum-score. Functional status was assessed using the 3-item Barthel Index (BI-3) and the General Physical Mobility Score (GPMS). Early assisted-tailored rehabilitation protocol was applied in ICU and in MCU: the aims were the maintenance (or recovery) of the range of motion and of the strength and the recovery of sitting/standing position and gait.

RESULTS

We evaluated 116 patients (mean age 65, SD 11) (65% male), 68 in ICU (mean age 60, SD 10), 48 in MCU (mean age 73, SD 9). At discharge, BI-3 and GPMS significantly improved in both ICU (P<0.001) and MCU (P<0.001) subgroups of patients. MRC sum-score significantly improved in ICU patients (P<0.001). Patients hospitalized in ICU had a significantly longer hospital stay. At discharge, patients admitted to the ICU reach a functional state that is close to that of patients admitted to the MCU.

CONCLUSIONS

The results suggest that an early assisted rehabilitation program may be helpful in improving the short-term functional status of an acutely hospitalized population affected by COVID-19, with discharge at home of 48% CLINICAL REHABILITATION IMPACT: this study focuses on a functional assessment method to be used to identify the rehabilitation needs and verify the results of an early rehabilitation protocol applied to the acute COVID-19 patient admitted to ICU and MCU.

A Telerehabilitation Approach to Chronic Facial Paralysis in the COVID-19 Pandemic Scenario: What Role for Electromyography Assessment?

There is a lack of data on patient and diagnostic factors for prognostication of complete recovery in patients with peripheral facial palsy. Thus, the aim of this study was to evaluate the role of a telerehabilitave enhancement through the description of a case report with the use of short-wave diathermy and neuromuscular electrical stimulation combined to facial proprioceptive neuromuscular facilitation (PNF) rehabilitation in unrecovered facial palsy, in a COVID-19 pandemic scenario describing a paradigmatic telerehabilitation report. A 43-year-old woman underwent a facial rehabilitation plan consisting of a synergistic treatment with facial PNF rehabilitation, short-wave diathermy, and neuromuscular electrical stimulation (12 sessions lasting 45 min, three sessions/week for 4 weeks). Concerning the surface electromyography evaluation of frontal and orbicularis oris muscles, the calculated ratio between amplitude of the palsy side and normal side showed an improvement in terms of movement symmetry. At the end of the outpatient treatment, a daily telerehabilitation protocol with video and teleconsultation was provided, showing a further improvement in the functioning of a woman suffering from unresolved facial paralysis. Therefore, an adequate telerehabilitation follow-up seems to play a fundamental role in the management of patients with facial palsy.

Long COVID Through a Public Health Lens: An Umbrella Review

Objectives: To synthesize existing evidence on prevalence as well as clinical and socio-economic aspects of Long COVID. Methods: An umbrella review of reviews and a targeted evidence synthesis of their primary studies, including searches in four electronic databases, reference lists of included reviews, as well as related article lists of relevant publications. Results: Synthesis included 23 reviews and 102 primary studies. Prevalence estimates ranged from 7.5% to 41% in non-hospitalized adults, 2.3%-53% in mixed adult samples, 37.6% in hospitalized adults, and 2%-3.5% in primarily non-hospitalized children. Preliminary evidence suggests that female sex, age, comorbidities, the severity of acute disease, and obesity are associated with Long COVID. Almost 50% of primary studies reported some degree of Long COVID-related social and family-life impairment, long absence periods off work, adjusted workloads, and loss of employment. Conclusion: Long COVID will likely have a substantial public health impact. Current evidence is still heterogeneous and incomplete. To fully understand Long COVID, well-designed prospective studies with representative samples will be essential.

Rehabilitation of COVID-19 patients with respiratory failure and critical illness disease in Slovenia: an observational study

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection often causes pneumonia and respiratory failure that may lead to postintensive care syndrome, including critical illness neuropathy (CIN) and critical illness myopathy (CIM). The data on the rehabilitation outcomes of post-novel coronavirus disease (COVID) patients with CIN and CIM following respiratory failure and mechanical ventilation are still limited. To address this, we enrolled in our prospective observational study a sample of 50 consecutive COVID-19 patients admitted to our facility between 2 November 2020 and 3 May 2021 with electrophysiologically confirmed or clinically suspected diagnosis of CIN/CIM. The functional abilities were assessed at admission and discharge with the Functional Independence Measure (FIM), The Canadian Occupational Performance Measure, 10-metre walk test, 6-min walk test and the de Morton Mobility Index. The gain in motor FIM and the length of stay were used as an index of rehabilitation efficiency. Nutritional status was also assessed using anthropometric measurements and bioelectrical Impedance analysis. Psychologic evaluation was performed at admission only. At admission, functional limitations and severe malnutrition were present in all patients with psychologic problems in about one third. At discharge (42 ± 16 days later), clinically important and statistically significant improvements were found in all outcome measures, which was also noted by the patients. The gain in motor FIM was larger with the longer length of stay up to 2 months and plateaued thereafter. We conclude that post-COVID-19 patients who develop CIN/CIM following respiratory failure can improve functional and nutritional status during inpatient rehabilitation.

Neuromuscular Impairment of Knee Stabilizer Muscles in a COVID-19 Cluster of Female Volleyball Players: Which Role for Rehabilitation in the Post-COVID-19 Return-to-Play?

COVID-19 athletes reported persistent and residual symptoms many weeks after initial infection, including cough, fatigue, and neuromuscular disorders. Poor neuromuscular control may cause inefficient movement strategies increasing anterior cruciate ligament load. This is particularly relevant in female athletes, who show a 3-time higher risk than male counterparts. Aim is to evaluate the impairment in thigh muscles activation, body composition, and physical performance after COVID-19 in volleyball athletes. We recruited a cohort of female professional players from the same team. We assessed the pre-activation time of Rectus Femoris (RF), Vastus Medialis (VM), Medial Hamstring (MH), and Lateral Hamstring (LH) before (T0) and after (T1) COVID-19 infection, bioelectrical impedance analysis (BIA), and jump tests. We included 12 athletes with COVID-19 infection diagnosis in January 2021. At T1 we found a significant (p < 0.05) delay (ms) of the activation time of RF (426 ± 188 vs. 152 ± 106); VM (363 ± 192 vs. 140 ± 96); BF (229 ± 60 vs. 150 ± 63); MH (231 ± 88 vs. 203 ± 89), and a significant reduction of body composition at BIA. The neuromotor imbalance of the knee stabilizer muscle in female athletes after COVID-19 infection determines a deficit of knee stabilization. Physicians should consider neuromuscular and metabolic sequelae to identify athletes at higher risk of injury and set up specific neuromuscular rehabilitation protocols.

Psychological Distress and Work Environment Perception by Physical Therapists from Southern Italy during COVID-19 Pandemic: The C.A.L.A.B.R.I.A Study

The psychosocial impact of the work environment during the COVID-19 pandemic on health professionals is a growing issue. The present study examined specific psychosocial work environment indicators during the COVID-19 pandemic, through a multiple regression model of a self-administered cross-sectional online survey in a cohort of physical therapists from a region of Southern Italy from March 2020 to May 2021. The questionnaire contained items on work and healthcare issues related to COVID-19. Eighty physical therapists (29 male and 51 female), mean age 32.5 ± 10.1 years, were involved in this survey. The multiple regression analysis showed that "management activity" was significantly correlated to "therapist frustration" during the COVID-19 pandemic (ΔR2 = 0.16; p < 0.03). Findings of this study underline the importance of a healthy psychosocial work environment to enhance job satisfaction of all health professionals and to avoid role conflict and burnout syndrome during the COVID-19 pandemic.

Case Report: Rehabilitation After Platelet-Rich Growth Factors' Intra-Articular Injections for Knee Osteoarthritis: Two Case Reports of a Home-Based Protocol

Knee osteoarthritis (KOA) is a chronic progressive disease that can cause pain, functional impairment, and ultimately disability. A novel and promising therapeutic approach to KOA is the so-called regenerative medicine, a set of procedures designed to harness tissue regenerative capacity and optimize functional recovery. Increasing evidence points out that platelet-rich plasma (PRP) intra-articular injections can decrease pain and improve functional abilities in KOA patients. In the present case reports, we analyze two patients who were treated with PRP injections coupled with a posttreatment home-based rehabilitation program. The two patients were selected to represent two different populations: patient 1 was an 85-year-old with severe impairment of functional abilities, while patient 2 was a younger (59 years old) and more active patient. The protocol consisted in a series of exercise to be performed at home, during the five days following PRP injection for two consecutive weeks (10 days in total). The exercises were designed to reduce the inflammation after the injection, enhance the proprioceptive control of the treated lower limb, and strengthen hip and knee flexors and extensors, mainly by isometric work. Results were evaluated at two time points: before and 2 months after the first PRP injection. The outcomes considered were as follows: visual analog scale for pain, EuroQol 5 dimensions questionnaire, Tegner Activity Scale for functioning, and Knee Injury and Osteoarthritis Outcome Score (KOOS). Both patients did not report any side effects from the treatment. Improvement in patient 1 was drastic at the two months follow-up as far as pain and functional abilities are concerned. Patient 2’s improvement was less evident, probably due to the higher starting point in both pain and functionality. Overall, the developed program seemed safe and was tolerated by the patients analyzed in the study, who performed it with good compliance.

Effectiveness of a Three-Week Inpatient Pulmonary Rehabilitation Program for Patients after COVID-19: A Prospective Observational Study

For COVID-19 patients who remain symptomatic after the acute phase, pulmonary rehabilitation (PR) is recommended. However, only a few studies have investigated the effectiveness of PR, especially considering the duration between the acute phase of COVID-19 and the onset of rehabilitation, as well as the initial severity. This prospective observational study evaluated the efficacy of PR in patients after COVID-19. A total of 120 still-symptomatic patients referred for PR after overcoming acute COVID-19 were asked to participate, of whom 108 (mean age 55.6 ± 10.1 years, 45.4% female) consented. The patients were assigned to three groups according to the time of referral and initial disease severity (severe acute; severe after interval; mild after interval). The primary outcome was dyspnea. Secondary outcomes included other respiratory disease symptoms, physical capacity, lung function, fatigue, quality of life (QoL), depression, and anxiety. Furthermore, patients rated the overall effectiveness of PR and their subjective change in health status. At the end of PR, we detected improvements with large effect sizes in exertional dyspnea, physical capacity, QoL, fatigue, and depression in the overall group. Other parameters changed with small to medium effect sizes. PR was effective after acute COVID-19 in all three groups analyzed.

Longitudinal observational study of boxing therapy in Parkinson's disease, including adverse impacts of the COVID-19 lockdown

BACKGROUND

Parkinson's Disease (PD) is a highly prevalent neurodegenerative disease whose incidence is increasing with an aging population. One of the most serious manifestations of PD is gait instability, leading to falls and subsequent complications that can be debilitating, even fatal. Boxing therapy (BT) uses gait and balance exercises to improve ambulation in people with PD, though its efficacy has not yet been fully proven.

METHODS

In the current longitudinal observational study, 98 participants with idiopathic PD underwent twice-weekly BT sessions. Primary outcome was self-reported falls per month; secondary outcomes were quantitative and semi-quantitative gait and balance performance evaluations. Statistical methods included segmented generalized estimating equation with an independent correlation structure, binomial distribution, and log link.

RESULTS

The average number of self-reported falls per month per participant decreased by 87%, from 0.86 ± 3.58 prior to BT, to 0.11 ± 0.26 during BT. During the lockdown imposed by COVID-19, this increased to 0.26 ± 0.48 falls per month. Females and those > 65 years old reported the greatest increase in falls during the lockdown period. Post-lockdown resumption of BT resulted in another decline in falls, to 0.14 ± 0.33. Quantitative performance metrics, including standing from a seated position and standing on one leg, largely mirrored the pattern of falls pre-and post-lockdown.

CONCLUSIONS

BT may be an effective option for many PD patients.

Occupational Therapy in Postacute Care for Survivors of COVID-19: Research Gaps We Need to Fill

This column discusses issues in the delivery of postacute care (PAC) rehabilitation services for coronavirus disease 2019 (COVID-19) survivors and gaps in the current research. Occupational therapy practitioners must not only better understand factors that influence the type of PAC rehabilitation a COVID-19 survivor will receive but also comprehend how wide variations in delivery of PAC occupational therapy have affected important outcomes for survivors. The COVID-19 Rehabilitation Research Framework, developed by Cochrane Rehabilitation and the World Health Organization Rehabilitation Program, offers a guide for occupational therapy research priorities that may fill two important gaps: (1) the need for high-quality PAC rehabilitation studies and (2) the need for research on activity and participation assessments and outcomes for COVID-19 survivors. Using electronic health records and other data sources, occupational therapy practitioners and researchers can help build the evidence base to support and guide PAC rehabilitation for survivors of COVID-19 and, perhaps, future pandemics.

Rehabilitation needs and mortality associated with the Covid-19 pandemic: a population-based study of all hospitalised and home-healthcare individuals in a Swedish healthcare region

BACKGROUND

This first report of the Linköping Covid-19 Study (LinCoS) aimed at determination of Covid-19-associated mortality, impairments, activity and participation limitations denoting rehabilitation needs four months after discharge from hospital.

METHODS

An ambidirectional population-based cohort study including all confirmed Covid-19 cases admitted to hospital during 1/03-31/05 and those living in home healthcare settings identified through a regional registry and evaluated through medical records, including WHO Clinical Progression Scale (CPS). All patients discharged from hospital were followed-up by structured telephone interview at 4 months post-discharge. Respondents indicated any new or aggravated persisting problems in any of 25 body functions and 12 activity/participation items and rated them for impact on daily life.

FINDINGS

Out of 734 hospitalised patients, 149 were excluded, 125 died, and 460 were alive at 4-month follow-up of whom 433 (94.1%) were interviewed. In total, 40% reported impairments and activity/participation limitations affecting daily life and warranted further multi-professional rehabilitation assessment, predominantly those with severe disease and a considerable proportion of those with moderate disease. Cognitive and affective impairments were equally common in all groups and were reported by 20-40% of cases. Limb weakness was reported by 31%, with CPS 7-9 being four times more likely to report this problem as compared to CPS 4-5. 26% of those working or studying reported difficulties returning to these activities, this being 3.5 times more likely in CPS 7-9 as compared to CPS 4-5. 25% reported problems walking >1 km, with CPS 7-9 over three times more likely to report this as compared to the other two sub-groups. 90-day mortality rate of Covid-19 associated deaths was 15.1%.

INTERPRETATION

Most rehabilitation needs after Covid-19 involved higher cerebral dysfunction both in patients with moderate and severe disease. This should be considered when designing services aiming at minimizing long-term disability.

Physical and Mental Fatigue in Subjects Recovered from COVID-19 Infection: A Case-Control Study

PURPOSE

Much effort has been directed toward studying COVID-19 symptoms; however, the post-COVID-19 phase remains mysterious. The aim of this work was to conduct a clinical and neurophysiological evaluation of physical and mental fatigue in COVID-19 long-haulers and to study whether markers of COVID-19 severity are able to predict the likelihood of developing postinfectious fatigue syndrome (PIFS) in such patients.

PATIENTS AND METHODS

This case-control study was conducted on 46 COVID-19 long-haulers who met the criteria for PIFS and 46 recovered COVID-19 subjects without any residuals. Clinical assessment of fatigue was done using a fatigue questionnaire. Repetitive nerve stimulation and single-fiber electromyography were done after excluding neuropathy and myopathy.

RESULTS

The median value for physical fatigue was 4 (IQR 2-7), while that for mental fatigue was 2 (IQR 0-3). Each day's increase in the period of COVID-19 illness increased the odds of PIFS in COVID-19 long-haulers 1.104-fold, and each unit increase in ferritin increased the odds of PIFS 1.006-fold. A significant decrement in at least one muscle was observed in 50% of patients. Patients with PIFS had significantly higher mean consecutive difference (MCD) in the extensor digitorum communis than the control group. There were statistically significant positive correlations between MCD values and physical, mental, and total fatigue scores.

CONCLUSION

Higher ferritin levels and prolonged COVID-19 infection were independent predictors of PIFS in COVID-19 long-haulers. There was electrophysiological evidence of abnormalities in the peripheral portion of the motor unit in COVID-19 long-haulers with PIFS.
