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

Tackling persistent neurological symptoms in patients following acute COVID-19 infection: an update of the literature

INTRODUCTION

The COVID-19 pandemic has taught myriad lessons and left several questions we are yet to comprehend. Initially, the scientific community was concerned with the management of acute disease and immunization. Once the peak of the pandemic receded, it became clear that a proportion of patients were far from fully recovered. Researchers started to recognize those persisting symptoms as a new entity termed 'Long COVID,' where neurological symptoms are evident and have a major impact on quality of life.

AREAS COVERED

The main purpose of this narrative review is to analyze and synthesize the current literature regarding Long COVID, its relation to the nervous system, and to explore the evidence on treatments for persistent neurological symptoms. The most common reported and observed neurologic manifestations include fatigue, cognitive impairment, pain, polyneuropathy, and neuropsychiatric disorders. A variety of pharmacologic and non-pharmacologic therapies have been evaluated and yielded mixed results. Many of them focused on immunomodulation and none currently have U.S. FDA approval.

EXPERT OPINION

Challenges remain in terms of clinical characterization and prognosis of Long COVID, besides understanding its pathophysiology. Standardization of biomarkers and diagnostic criteria will allow the use of common nomenclature and data elements in the design of future clinical studies.

Impact of post-COVID symptoms on activity and participation of women and men

Post-COVID syndrome is affecting many organ systems and arises as a major public health problem with millions of cases worldwide. The primary aim of this study is the analysis of health problems, activity limitations and participation restrictions (ALPR) of participants with post-COVID symptoms and the investigation of correlations between these elements to derive statements about the rehabilitation need, also depending on sex. A retrospective cohort study was performed to collect longitudinal data from January 2022 to January 2023 using the Covid-19 Rehabilitation Needs Questionnaire (RehabNeQ). Patients completed the questionnaire at the Department of Rehabilitation- and Sports Medicine at Hannover Medical School. The 1st assessment included 307 study participants, of whom 54 showed up for the 2nd, 7 for the 3rd and one for the 4th assessment. Study participants with post-COVID symptoms also experience ALPR. The results show no significant difference in symptom intensity in women and men, but in intensity of ALPR. We found many correlations of varying degrees between various factors with ALPR. We found frequent correlations between fatigue and several ALPR. While these correlations apply to both sexes, we also found different correlations in women and men, indicating the different rehabilitation need of women and men.

Patient Experiences Navigating Care Coordination For Long COVID: A Qualitative Study

BACKGROUND

Little is known about how to best evaluate, diagnose, and treat long COVID, which presents challenges for patients as they seek care.

OBJECTIVE

Understand experiences of patients as they navigate care for long COVID.

DESIGN

Qualitative study involving interviews with patients about topics related to seeking and receiving care for long COVID.

PARTICIPANTS

Eligible patients were at least 18 years of age, spoke English, self-identified as functioning well prior to COVID infection, and reported long COVID symptoms continued to impact their lives at 3 months or more after a COVID infection.

APPROACH

Patients were recruited from a post-COVID recovery clinic at an academic medical center from August to September 2022. Interviews were audio-recorded, transcribed, and analyzed using thematic analysis.

KEY RESULTS

Participants (n=21) reported experiences related to elements of care coordination: access to care, evaluation, treatment, and ongoing care concerns. Some patients noted access to care was facilitated by having providers that listened to and validated their symptoms; other patients reported feeling their access to care was hindered by providers who did not believe or understand their symptoms. Patients reported confusion around how to communicate their symptoms when being evaluated for long COVID, and they expressed frustration with receiving test results that were normal or diagnoses that were not directly attributed to long COVID. Patients acknowledged that clinicians are still learning how to treat long COVID, and they voiced appreciation for providers who are willing to try new treatment approaches. Patients expressed ongoing care concerns, including feeling there is nothing more that can be done, and questioned long-term impacts on their aging and life expectancy.

CONCLUSIONS

Our findings shed light on challenges faced by patients with long COVID as they seek care. Healthcare systems and providers should consider these challenges when developing strategies to improve care coordination for patients with long COVID.

Practical Recommendations for Exercise Training in Patients with Long COVID with or without Post-exertional Malaise: A Best Practice Proposal

People with long COVID may suffer from a wide range of ongoing symptoms including fatigue, exertional dyspnea, reduced exercise performance, and others. In particular, impaired exercise performance is a condition that can be recovered in many people through an individualized physical exercise training program. However, clinical experience has shown that the presence of post-exertional malaise (PEM) is a significant barrier to physical exercise training in people with long COVID. Currently, there is no guideline or consensus available on how to apply exercise training in this cohort. Therefore, we conducted a literature review in the PubMed library using the following search terms: "COVID", "post-COVID", "long COVID" and "exercise" searching for studies from January 2020 to January 2024. Data from 46 trials were included. Exercise training regimes were very heterogeneous and none of these studies reported on the management of PEM in the context of an exercise training program. Based on the feedback from an additional survey that was answered by 14 international experts in the field of exercise training in long COVID, combined with the authors´ own extensive practical experience, a best practice proposal for exercise training recommendations has been developed. This proposal differentiates exercise procedures according to the presence of no, mild/moderate or severe PEM in people with long COVID. These recommendations may guide allied healthcare professionals worldwide in initiating and adjusting exercise training programs for people with long COVID, stratified according to the presence and severity of PEM.

Evidence-based rehabilitation medicine: definition, foundation, practice and development

To determine the definition, foundation, practice, and development of evidence-based rehabilitation medicine (EBRM) and point out the development direction for EBRM. Retrieve the database of PubMed, Cochrane Library, Embase, China national knowledge infrastructure (CNKI), Wanfang, and China science and technology journal database (CSTJ). The search was conducted from the establishment of the database to June 2023. The key words are "rehabilitation medicine and evidence based" in Chinese and English. After reading the abstract or full text of the literature, a summary analysis is conducted to determine the definition, foundation, practice, and development of EBRM. A total of 127 articles were included. The development of 14 sub majors in EBRM are not balanced, evidence-based musculoskeletal rehabilitation medicine (EBMRM) (31 articles, mainly focuses on osteoarthritis, osteoporosis and musculoskeletal pain), evidence-based neurorehabilitation medicine (EBNM) (34 articles, mainly concentrated in stroke, traumatic brain injury and spinal cord injury) and evidence-based education rehabilitation medicine (EBEDRM) (17 articles, mainly focuses on educational methodology), evidence-based nursing rehabilitation medicine (EBNRM) (2 articles), evidence-based engineering rehabilitation medicine (EBENRM) (7 articles), evidence-based traditional Chinese rehabilitation medicine (EBTCRM) (3 articles), evidence-based internal rehabilitation medicine (EBIRM) (11 articles), evidence-based intensive care rehabilitation medicine (EBICRM) (4 articles), evidence-based oncology rehabilitation medicine (EBORM) (6 articles), evidence-based physical therapy medicine (EBPTM) (3 articles), evidence-based cardiopulmonary rehabilitation medicine (EBCRM) (6 articles), evidence-based speech therapy medicine (EBSTM)/evidence-based occupation therapy medicine (EBOTM)/evidence-based geriatric rehabilitation medicine (EBGRM) (1 article). The EBMRM, EBNM and EBEDRM are relatively well developed. The development of EBNRM, EBENRM, EBTCRM, EBIRM, EBICRM, EBGRM, EBORM, EBCRM, EBPTM, EBSTM and EBOTM is relatively slow, indicating these eleven fields should be pay more attention in future.

Do implementation interventions improve evidence-based care in acute stroke settings? A Cochrane Review summary with commentary

BACKGROUND

Evidence on acute stroke management is continuously growing. Stroke units are often associated with better access to high-level evidence-based practices, but even there, recommendations can be inconsistently delivered to patients with stroke. Implementation interventions are strategies designed to improve the application of evidence-based care.

OBJECTIVE

To provide a commentary on the Cochrane Review by Lynch et al. on the effects of implementation interventions on adherence to evidence-based recommendations by health professionals working in acute stroke units.

METHODS

A systematic search was performed in CENTRAL, MEDLINE, Embase, and other databases. The search was also performed in grey literature databases, trial registries, systematic reviews and primary studies, as well as in the reference list of identified studies.

RESULTS

The review included seven cluster-randomized trials (with 42,489 participants). Studies compared the implementation of strategies composed of different parts (multifaceted) to no intervention, or a multifaceted strategy vs another intervention. These strategies were aimed at changing and improving the delivery of care in the hospital. It included health professional participants, such as nurses, physicians and allied health professionals. The authors concluded that there was uncertainty whether implementation strategies compared with no intervention have any effect on patients receiving evidence-based care during their stroke unit admission. Implementation interventions compared to no intervention probably have little or no effect on the risk of patients dying or being disabled or dependent, and probably do not change patients' hospital length of stay.

CONCLUSION

Due to the very low certainty of evidence, there is uncertainty whether a multifaceted implementation intervention, compared to no intervention, can improve adherence to evidence-based recommendations in acute stroke settings.

Dyspnea: a map of Cochrane evidence relevant to rehabilitation for people with post COVID-19 condition

INTRODUCTION

Rehabilitation focuses on impairments, activity limitations and participation restrictions being informed by the underlying health condition. In the current absence of direct "evidence on" rehabilitation interventions for people with post COVID-19 condition (PCC), we can search and synthesize the indirect "evidence relevant to" coming from interventions effective on the symptoms of PCC in other health conditions. The World Health Organization (WHO) required this information to inform expert teams and provide specific recommendations in their Guidelines. With this overview of reviews with mapping we aimed to synthesize in a map the Cochrane evidence relevant to rehabilitation for dyspnea due to PCC.

EVIDENCE ACQUISITION

We searched the last five years' Cochrane Systematic Review (CSRs) using the terms "dyspnea" and its synonyms in the Cochrane Library. We extracted and summarized all the available evidence using a map. We grouped the included CSRs for health conditions and interventions, indicating the effect and the quality of evidence.

EVIDENCE SYNTHESIS

We found 371 CSRs published between 2016 and 2021 and included 15 in this overview. We found eight studies on chronic obstructive pulmonary disease, two on cancer, and one for bronchiectasis, chronic respiratory disease, cystic fibrosis, idiopathic pulmonary fibrosis and interstitial lung disease. Effective interventions included pulmonary rehabilitation, also in combination with exercise training, non-invasive ventilation, upper limb training and multicomponent integrated interventions, with very low- to moderate-quality evidence.

CONCLUSIONS

These results are the first step of indirect evidence to generate helpful hypotheses for clinical practice and future research on dyspnea in adults with PCC. They served as the basis for one recommendation on treatments for dyspnea as a PCC symptom published in the current WHO Guidelines for clinical practice.

Dysphagia, dysphonia and olfactory disease: a map of Cochrane evidence relevant to rehabilitation for people with post COVID-19 condition

INTRODUCTION

Currently, no evidence exists on specific treatments for post COVID-19 condition (PCC). However, rehabilitation interventions that proved effective for similar symptoms in other health conditions could be applied to people with PCC. With this overview of systematic reviews with mapping, we aimed to describe the Cochrane evidence on rehabilitation interventions proposed for dysphagia, dysphonia and olfactory dysfunction in different health conditions that can be relevant for PCC.

EVIDENCE ACQUISITION

We searched the last five years' Cochrane Systematic Review (CSRs) using the terms "dysphagia," "swallowing disorder," "dysphonia," "voice disorder," "olfactory dysfunction," "smell changes" and "rehabilitation" in the Cochrane Library. We extracted and summarized the available evidence using a map. We grouped the included CSRs for health conditions and interventions, indicating the effect and the quality of evidence.

EVIDENCE SYNTHESIS

We found 170 CSRs published between 2016 and 2021 and 1 was included. It provided data on dysphagia in acute and subacute stroke. Interventions included were acupuncture, neuromuscular electrical stimulation, transcranial magnetic stimulation and behavioral interventions, and swallowing therapy, with very low- to moderate-quality evidence. We did not find any CSR on dysphonia and olfactory disease.

CONCLUSIONS

These results are the first step of indirect evidence able to generate helpful hypotheses for clinical practice and future research. They served as the basis for the three recommendations on treatments for these PCC symptoms published in the current WHO Guidelines for clinical practice.

We extracted and summarized the available evidence using a map. We grouped the included CSRs for health conditions and interventions, indicating the effect and the quality of evidence.

EVIDENCE SYNTHESIS

Out of 1397 CSRs published between 2016 and 2021, we included 32 for fatigue and 4 for exercise intolerance. They provided data from 13 health conditions, with cancer (11 studies), chronic obstructive pulmonary disease (7 studies), fibromyalgia (4 studies), and cystic fibrosis (3 studies) being the most studied. Effective interventions for fatigue included exercise training and physical activities, telerehabilitation and multicomponent and educational interventions. Effective interventions for exercise intolerance included combined aerobic/anaerobic training and integrated disease rehabilitation management. The overall quality of evidence was low to very low and moderate in very few cases. We did not identify CSRs that specifically addressed post-exertional malaise or orthostatic intolerance.

CONCLUSIONS

These results are the first step of indirect evidence able to generate helpful hypotheses for clinical practice and future research. They served as the basis for the three recommendations on treatments for these PCC symptoms published in the current WHO Guidelines for clinical practice.

Arthralgia: a map of Cochrane evidence relevant to rehabilitation for people with post COVID-19 condition

INTRODUCTION

Rehabilitation focuses on impairments, activity limitations and participation restrictions being informed by the underlying health condition. In the current absence of direct "evidence on" rehabilitation interventions for people with post COVID-19 condition (PCC), we can search and synthesize the indirect "evidence relevant to" coming from interventions effective on the symptoms of PCC in other health conditions. The World Health Organization (WHO) required this information to inform expert teams and provide specific recommendations in its Guidelines. With this overview of reviews with mapping we aimed to synthesize the Cochrane evidence relevant to rehabilitation for arthralgia due to PCC in a map.

EVIDENCE ACQUISITION

We searched the last five years' Cochrane Systematic Review (CSRs) using the terms "arthralgia," "joint pain," and "rehabilitation" and their synonyms in the Cochrane Library. We extracted and summarized all the available evidence using a map. We grouped the included CSRs for health conditions and interventions, indicating the effect and the quality of evidence.

EVIDENCE SYNTHESIS

We found 200 CSRs published between 2016 and 2021, and included 11 in this overview. They provided data from 7 health conditions, with osteoarthritis (5 studies) being the most studied. Effective rehabilitation interventions included exercise training, transcranial magnetic stimulation, different types of electrical stimulation and Tai chi. The overall quality of evidence was mainly low to very low, and moderate in a few cases.

CONCLUSIONS

These results provided the requested information to the WHO and served as the basis for one recommendation on treatments for arthralgia due to PCC in the current Guidelines for clinical practice. These results should be interpreted as a first step of indirect evidence able to generate helpful hypotheses for future research.

Cognitive impairment, anxiety and depression: a map of Cochrane evidence relevant to rehabilitation for people with post COVID-19 condition

INTRODUCTION

Currently, no evidence exists on specific treatments for post COVID-19 condition (PCC). However, rehabilitation interventions that are effective for similar symptoms in other health conditions could be applied to people with PCC. With this overview of systematic reviews with mapping, we aimed to describe the Cochrane evidence on rehabilitation interventions proposed for cognitive impairment, anxiety and depression in different health conditions that can be relevant for PCC.

EVIDENCE ACQUISITION

We searched the last five years' Cochrane Systematic Review (CSRs) using the terms "cognitive impairment," "depressive disorder," "anxiety disorder," their synonyms and variants, and "rehabilitation" in the Cochrane Library. We extracted and summarized the available evidence using a map. We grouped the included CSRs for health conditions and interventions, indicating the effect and the quality of evidence.

EVIDENCE SYNTHESIS

We found 3596 CSRs published between 2016 and 2021, and we included 17 on cognitive impairment and 37 on anxiety and depression. For cognitive impairment, we found 7 CSRs on participants with stroke, 3 with cancer, 2 with Parkinson's disease, and one each for five other health conditions. Each intervention improved a different domain, and included exercises, cognitive and attention-specific training, and computerized cognition-based training (from very low to high-quality evidence). For anxiety and depression, we found 10 CSRs including participants with cancer, 8 with stroke, 3 with chronic obstructive pulmonary disease, and 2 or 1 each in 11 other health conditions. Exercise training, physical activity and yoga resulted effective in several pathologies (very low- to moderate-quality evidence). In specific diseases, we found effective acupuncture, animal-assisted therapy, aromatherapy, educational programs, home-based multidimensional survivorship programs, manual acupressure massage, memory rehabilitation, non-invasive brain stimulation, pulmonary rehabilitation, and telerehabilitation (very low- to moderate-quality evidence).

CONCLUSIONS

These results are the first step of indirect evidence able to generate helpful hypotheses for clinical practice and future research. They served as the basis for the three recommendations on treatments for these PCC symptoms published in the current WHO Guidelines for clinical practice.
