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.

Rehabilitation definition for research purposes. A global stakeholders' initiative by Cochrane Rehabilitation

Since its foundation, Cochrane Rehabilitation has faced challenges with rehabilitation definitions because existing definitions did not indicate what rehabilitation includes and what it excludes. We aimed to develop a comprehensive and shared rehabilitation definition for research purposes to: 1) support the conduct of primary studies and systematic reviews, and 2) identify relevant systematic reviews for knowledge translation purposes. We performed a multimodal study including seven preliminary research and discussion papers, four Consensus Meetings and three Delphi rounds with 80 rehabilitation stakeholders. The Delphi Study aimed to obtain agreement, refine and complete the items composing the definition and meanings of rehabilitation. These stakeholders covered 5 continents, representing 11 global and continental rehabilitation organizations, 11 scientific journals, 4 Cochrane Networks and 3 Cochrane Groups, and included invited experts, and representatives of low middle-income countries (LMICs) and consumers. We had a 70% to 82.5% response rate to the three Delphi rounds, during which participants responded to all items (100%) and provided relevant comments (range 5.5-50% per item). This participation led to several refinements to the rehabilitation definition through three preliminary versions, and the final items reached an agreement between 88.9% and 100%. We structured the definition using the PICO (Population, Intervention, Comparison, Outcome) framework. We concluded that "In a health care context," rehabilitation is defined as a "multimodal, person-centered, collaborative process" (Intervention-general), including interventions targeting a person's "capacity (by addressing body structures, functions, and activities/participation) and/or contextual factors related to performance" (Intervention-specific) with the goal of "optimizing" the "functioning" (Outcome) of "persons with health conditions currently experiencing disability or likely to experience disability, or persons with disability" (Population). Rehabilitation requires that all the items of the definition are satisfied. We defined a "rehabilitation intervention" as "any intervention provided within the rehabilitation process." We developed a rehabilitation definition for research purposes achieving a broad agreement with global stakeholders. This definition provides explicit criteria to define rehabilitation. Using the proposed definition will improve rehabilitation research by standardizing the description of interventions. Our definition may require revision in the future, as further research enhances understanding and communication of the essence and complexity of rehabilitation.

Rehabilitation Research in Denmark Between 2001 and 2020: A Scoping Review

The demand for rehabilitation has increased, and evidence is rapidly growing; however, a rehabilitative health strategy receives less attention than treatment. Knowledge of what is being researched, who are the target groups and who contributes to rehabilitation research is deficient. We did not find any reviews mapping rehabilitation research regarding the research questions. The objective was to identify and synthesize existing scientific evidence on rehabilitation research published by Danish institutions between 2001 and 2021. The research questions to be explored were: Among which study groups has rehabilitation research been published?. Which types of studies on rehabilitation have been published?. Which institutions have been involved in rehabilitation research?

Methods

The process was guided according to the Joanna Briggs Institute's (JBI's) scoping review methodology. Four databases were searched. All types of peer-reviewed studies on any target group and rehabilitation setting, with any affiliation to a Danish institution, were eligible to be included. Studies referring to population and the type of design were categorized. Institutions were counted as Danish first authorship.

Results

The search revealed 3,100 studies, and following screening 1,779 were included. A total of 24 broad study groups were identified, mostly diagnosis-based health conditions. Musculoskeletal, cancer, and cardiac had 342, 228, and 174 studies, respectively. A total of 1,545 had a Danish first authorship, most of the Danish publications came from hospitals (56.6%) and universities (28.4%). The publication trend showed an almost linear development, with a 10-15% increase during the period.

Conclusion

Following screening 1,779 studies were included involving 24 broad study groups. Most categories were diagnosis-based; musculoskeletal, cancer, and cardiac health conditions encompassed most studies. All study designs were represented, and 1/10 were secondary studies. The majority (87%) of studies had a Danish first authorship. The majority of first affiliations were among hospitals followed by universities. A few municipalities were presented although they are yet to have research responsibility. Publication trends showed an increase primarily from 2013.

Why we need an internationally shared rehabilitation definition for clinical research purposes

PURPOSE

Responding to a recent editorial arguing against defining rehabilitation, we discuss the reasons for developing a classification of rehabilitation for research purposes, its philosophical background and some of the possible risks.

WHY DEFINE

Science requires the definition and classification of phenomena to allow replication of experiments and studies, and to allow interpretation and use of the findings. As understanding increases, the definitions can be refined. Defining rehabilitation does run the risk of excluding some interventions or practices that are either considered rehabilitation (perhaps wrongly) or are rehabilitation interventions; when identified, these errors in definition can be remedied. Defining rehabilitation for research purposes should not inhibit but could (possibly) orient research.

RISK OF NOT

Without a definition, rehabilitation will remain in a permanent limbo. Experts will (apparently) know what it is, while others are left guessing or failing to comprehend or recognise it. This uncertainty may reassure some people, because all possible interventions are included; we argue that it downgrades the understanding of our field because interventions that are not rehabilitation are, nonetheless, called rehabilitation. In an era of international collaboration, and of undertaking systematic reviews with metanalysis, we need a shared definition.

CONCLUSION

Terminology is often controversial, but definition enables progress in understanding such that terms themselves can evolve over time.

Defining rehabilitation: An exploration of why it is attempted, and why it will always fail

The problem:

Over 187 definitions of rehabilitation exist, none widely agreed or used. Why?

The word:

Words represent a core concept, with a penumbra of associated meanings. A word means what is agreed among those who use it. The precise meaning will vary between different groups. Words evolve, the meaning changing with use. Other words may capture some of the concepts or meanings.

A definition:

A definition is used to control the unstable, nebulous meaning of a word. It delineates, creating a boundary. A non-binary spectrum of meaning is transformed into binary categories: rehabilitation, or not rehabilitation. In clinical terms, it is a diagnostic test to identify rehabilitation. There are many different reasons for categorising something as rehabilitation. Each will need its own definition.

Categorisation:

The ability of a definition to distinguish cases accurately must be validated by comparison with ‘the truth’. If there were an external ‘true’ test to identify rehabilitation, a definition would not be needed. As with most concepts, the only truth is agreement by people familiar with the required distinction. Any definition will generate misclassification. People familiar with the required distinction will also need to resolve mis-categorisation.

Description:

An alternative is a ‘descriptive definition’, listing features over several domains which must be present. This fails logically. Rehabilitation is an emergent concept, more than the sum of its parts.

Conclusion:

A useful definition cannot be achieved because no definition will cover all needs, and a specific definition for a purpose will misclassify some cases.

Cochrane Rehabilitation: 2020 annual report

During its fourth year of existence, Cochrane Rehabilitation went on to promote evidence-informed health decision-making in rehabilitation. In 2020, the outbreak of the COVID-19 pandemic has made it necessary to alter priorities. In these challenging times, Cochrane Rehabilitation has firstly changed its internal organisation and established a new relevant project in line with pandemic needs: the REH-COVER (Rehabilitation - COVID-19 evidence-based response) action. The aim was to focus on the timely collection, review and dissemination of summarised and synthesised evidence relating to COVID-19 and rehabilitation. Cochrane Rehabilitation REH-COVER action has included in 2020 five main initiatives: 1) rapid living systematic reviews on rehabilitation and COVID-19; 2) interactive living evidence map on rehabilitation and COVID-19; 3) definition of the research topics on "rehabilitation and COVID-19" in collaboration with the World Health Organization (WHO) rehabilitation programme; 4) Cochrane Library special collection on Coronavirus (COVID-19) rehabilitation; and 5) collaboration with COVID-END for the topics "rehabilitation" and "disability." Furthermore, we are still carrying on five different special projects: Be4rehab; RCTRACK; definition of rehabilitation for research purposes; ebook project; and a prioritization exercise for Cochrane Reviews production. The Review Working Area continued to identify and "tag" the rehabilitation-relevant reviews published in the Cochrane library; the Publication Working Area went on to publish Cochrane Corners, working more closely with the Cochrane Review Groups (CRGs) and Cochrane Networks, particularly with Cochrane Musculoskeletal, Oral, Skin and Sensory Network; the Education Working Area, the most damaged in 2020, tried to continue performing educational activities such as workshops in different online meetings; the Methodology Working Area organized the third and fourth Cochrane Rehabilitation Methodological (CRM) meetings respectively in Milan and Orlando; the Communication Working Area spread rehabilitation evidences through different channels and translated the contents in different languages.

Toward a new definition of rehabilitation for research purposes: a comparative analysis of current definitions

There is a need for a common, shared definition of rehabilitation to conduct systematic reviews and identify relevant systematic reviews for knowledge translation purposes, which is an important task of Cochrane Rehabilitation. The present paper aimed to introduce and compare existing health-related definitions of rehabilitation and to propose core aspects that should characterize a new and workable definition of rehabilitation that is able to serve both as the basis for internal communication and identity work and for external communication. We have conducted a PubMed literature search on current definitions that have been published since the launch of WHO's ICF in 2001. Definitions were analyzed by framing questions to which the definitions provide answers. Nine definitions were included in the analysis. Rehabilitation has been defined as a process, as a set or bundle of interventions, and as a health strategy. The main beneficiaries were mainly related to the presence of disability, however, no specific means or interventions in rehabilitation could be identified. The definitions provided varying answers to the questions "by whom…," "where…," and "when…" and additionally identified certain conditions for rehabilitation. The present analysis can serve as a valuable source of information for developing a Cochrane Rehabilitation definition of rehabilitation.
