Systematic Reviews and Clinical Trials in Rehabilitation: Comprehensive Analyses of Publication Trends

Occupational Therapy Research Publications From 2001 to 2020 in PubMed: Trends and Comparative Analysis with Physiotherapy and Rehabilitation

A limited understanding of trends in occupational therapy (OT) research publications exists. This study aimed to evaluate trends in OT research publications, in PubMed (2001-2020), compared to physiotherapy and rehabilitation. A method of secondary analysis of publication trends in the PubMed database was used. Medical subject headings for OT, physiotherapy, and rehabilitation were combined with search filters (e.g., population age, study design, and OT practice area). Linear regressions were computed to analyze changes in yearly growth. OT research publications increased by 5.86 per year and comprised less than 2.5% of rehabilitation research publications yearly. Knowledge synthesis was the predominant OT study design (2.94% yearly increase; p < .001). Intellectual/cognitive conditions and emergent practice areas in OT research publications increased over time (both p = .007). OT research publications were relatively evenly distributed across population age. OT research publications are increasing over time but lag relative to physiotherapy and rehabilitation broadly. Our findings may inform future OT research priorities.

Global research publications on cardiovascular and pulmonary rehabilitation and their alignment with population rehabilitation needs: An ecological study

PURPOSE

Towards informing health research policy and planning, this article evaluates the relationship of the research publications in cardiac rehabilitation (CR) and pulmonary rehabilitation (PR) with the rehabilitation needs arising from cardiovascular diseases (except stroke) and chronic respiratory diseases, over time (1990-2017).

METHODS

Ecological study using a secondary analysis and linear regressions of public domain data to associate two datasets of population-level data: (1) research publications for CR and PR (data from the PubMed database); and (2) global need for CR and PR (data from the Global Burden of Disease study).

RESULTS

The percentage of both CR and PR publications (among total rehabilitation research) significantly decreased from 1990 to 2017 (both: p < 0.01). PR needs and research publications were aligned: around 5% of total rehabilitation needs and rehabilitation research. For CR needs (around 2%, but significantly increasing since 1990), we found a greater portion of CR research publications (6.5% or over). Finally, we found an inverse association among the percentage of CR research publications and CR needs (b = -6.08; r2  = 0.37, p = 0.001).

CONCLUSION

The portion of CR and PR research (among total rehabilitation research) is declining over time. Yearly percentage of CR publications were greater than those of PR but for lower level of rehabilitation need, but the disparate trend was significantly decreasing over time. Population rehabilitation needs and their alignment with research volume must be one factor in the design of population-centred, equitable health research priorities.

Evolution of the thematic structure and main producers of physical therapy interventions research: A bibliometric analysis (1986 to 2017)

BACKGROUND

Bibliometric studies are used to analyse and map scientific areas, and study the scientific output and impact of institutes and countries.

OBJECTIVES

Describe the thematic structure and evolution of the field of physical therapy interventions using articles indexed in Physiotherapy Evidence Database (PEDro). Also, identify and compare the main producers (countries, institutions) over time (research output, citation impact).

METHODS

Eligible articles were those indexed in PEDro (1986-2017) and matched to Web of Science. VOSviewer software, bibliometric text mining, and visualisation techniques were used to evaluate the thematic structure of the included articles. We collected data about authors' country and institutional affiliation, and calculated bibliometric indicators (production, citation impact).

RESULTS

A total of 29 090 articles were analysed. Eight topics were identified: "neurological rehabilitation"; "methods"; "exercise for prevention and rehabilitation of lifestyle diseases"; "assessment and treatment of musculoskeletal pain"; "physical activity", "health promotion and behaviour change"; "respiratory physical therapy"; "hospital, primary care and health economics"; "cancer and complementary therapies". The most productive countries were United States, United Kingdom, Australia, and Canada. The most impactful countries were United States, France, Finland, and Canada. The most productive institutions were University of Sydney, VU University of Amsterdam, University of Queensland, and University of Toronto.

CONCLUSIONS

The thematic structure of physical therapy interventions has evolved over time with "neurological rehabilitation", "methods", "exercise related to lifestyle diseases", and "physical activity" becoming increasingly important. Main producers of this research were traditionally located in North America and Europe but now include countries like China and Brazil.

Global health workforce research: Comparative analyses of the scientific publication trends in PubMed

AIM

To analyse the amount of Human Resources for Health (HRH) research publication trends [1990-2019], compared to the broader health policy, systems, and services research (HPSSR).

METHODS

PubMed and its indexation system with Medical Subject Headings (MeSH) are used for this time-trend study. Searches combine MeSH terms for research publications and HPSSR or HRH subjects, except education. Sub-group searches are conducted on: funding support, and high- versus low- and middle-income countries (HICs vs. LMICs). Linear regressions are used for the analysis.

RESULTS

HRH research publications rose exponentially (r²  = 0.94; p < 0.001) from 129 yearly publications in 1990, to 867 in 2018. Yet, HRH research publications had a logarithmic decrease (p < 0.001) in percentage of broader HPSSR publications, from 2.5% to 1.5% [1990-2018]. Funding support increased significantly and linearly (p < 0.001 r²  = 0.88), up to 44% in 2018. The percentage of HRH research publications addressing LMICs grew linearly (p < 0.001; r²  = 0.75), up to 23% in 2018.

CONCLUSION

HRH research publications in the PubMed database increased especially in the more recent years but did not outpace (in earlier times was outpaced) by the growth of HPSSR publications overall. Yearly, HICs still accounted for more than three-quarters of HRH research. These findings can inform global and health research policies.

Espí-López G. Bibliometric analysis of productivity and keyword trends of articles on physical therapy and aging (1990-2014)

Introduction

The increase in population longevity has led the subject of ageing to take an important role in research and innovation policies. Considerable efforts have been made worldwide to promote research on physiotherapy and ageing. Therefore, applying bibliometric measures can be useful to identify emerging and innovative scientific indicators. This study identifies productivity and topic trends in physiotherapy in ageing and the main publishing authors, institutions, and countries.

Methods

A bibliometric analysis was applied in original articles published on the Science Citation Index Expanded of Web of Science Core Collection (1990–2014). Bibliometric indicators were obtained by using specific bibliometric software. Pearsons’ correlation coefficient (r) was applied for correlations; statistical significance was considered for <i>p</i> < 0.01.

Results

Overall, 2237 original articles were included. Topic trends show an initial focus on illness and evolve towards the study of prevention. Authors and institutions increased productivity and citation. The most productive country was the United States, and there was a significant correlation between productivity and gross domestic product (<i>p</i> < 0.01). No statistically significant relationship was observed between productivity and the countries’ aged population.

Conclusions

Productivity increased, with a greater scientific interest in prevention. The published research was mainly related to wealthy and developed countries.

Publication Trends in Physical Medicine and Rehabilitation in Japan from 2001 to 2019

Objectives

The aim of this study was to examine, using PubMed, the number of articles in the field of physical medicine and rehabilitation medicine originating in Japan, especially those containing high-quality scientific evidence (randomized controlled trials [RCTs], systematic reviews, meta-analyses) and those published in high impact factor journals.

Methods

We searched the PubMed database to identify articles, RCTs, systematic reviews, and meta-analyses from Japan covering physical medicine and rehabilitation published between 2001 and 2019; we then calculated the proportion of articles from Japan. Additionally, using Journal Citation Reports, we selected the top ten highest impact factor journals on "Rehabilitation" each year between 2001 and 2019. For each year, we searched PubMed for the total number of articles in these top ten journals and for articles originating in Japan. The Cochran-Armitage test was used to evaluate the change in the proportion of publications from Japan over time.

Results

The proportion of articles on physical medicine and rehabilitation originating in Japan increased from 2001 to 2019 (P<0.0001). An increase in the percentages of systematic reviews (P=0.046) and meta-analyses (P=0.0013) originating in Japan and a decrease in the percentage of original articles published in the top ten highest impact factor journals were demonstrated (P=0.002). However, there was no change in the percentage of RCTs from Japan over time (P=0.055).

Conclusions

Our findings suggest that the proportion of articles from Japan containing high-quality scientific evidence is increasing. However, there is a need to expand the support system for research while considering the quality of research.

Scoping review of the person-centered literature in adult physical rehabilitation

PURPOSE

To describe the amount, range, and key characteristics (e.g., publication years, methods, topics) of the person-centered rehabilitation literature in adults with physical impairments.

METHOD

Following the published scoping review protocol, papers were identified through: three major databases, snowball searches and expert consultation. Two independent reviewers have identified English-language papers on adult person-centered rehabilitation according to six pre-defined inclusion categories - theoretical, quantitative and qualitive research papers are included; and then have extracted their key characteristics (e.g., aims, methods, participants). Descriptive statistics, regression and content analyses were used to synthesize the results.

RESULTS

Of 5912 deduplicated records initially screened, 170 papers were included: 136 empirical, including 13 systematic reviews. Empirical papers had data from 15264 clients and 4098 providers, in total. Yearly publications grew significantly from 2009 to 2018 (r2 = 0.71; b = 1.98: p < 0.01). Publications were unevenly distributed by countries (e.g., United States' publications per population was 44 times lower than New Zealand's). Most papers focused in more than one profession, setting-type or health conditions. Finally, many empirical papers (n = 67) studied implementation of person-centered rehabilitation approaches, including its effect.

CONCLUSION

This scoping review synthesizes key characteristics and publication trends in the person-centered rehabilitation literature on adults with physical impairments, a growing but unchartered territory thus far. This large and diverse body of literature can ground further person-centered rehabilitation practices and research, including toward building a transdisciplinary, trans-service model of person-centered rehabilitation.Implications for rehabilitationThe person-centered rehabilitation literature on adults with physical impairments, especially the empirical one, has been growing significantly over time, despite inequitably distributed per countries.Rehabilitation stakeholders, including practitioners, have a growing amount of literature in which they can rely for the operationalization and implementation of person-centered rehabilitation approaches into routine practice.Based on our work, person-centered rehabilitation emerges as a practice requirement that cuts across professional and other rehabilitation silos.

Representation in rehabilitation research of adults with traumatic brain injury and depression: A scoping review

Objective: To determine how well comorbid depression is described, defined, and measured in the rehabilitation literature that pertains to TBI and depression.Method: Scoping review of the rehabilitation sciences literature. Six databases were searched (to October 17, 2018) using the three core concepts of TBI, depression, and rehabilitation, as was for gray literature. Two independent reviewers reviewed documents for eligibility.Results: 3737 records were reviewed and 137 documents were analyzed. Primary studies (n = 126) were most prevalent and of quantitative descriptive design (n = 102). The number of participants with TBI and comorbid depression could only be determined for 81/126 (64%) of primary studies, in which they are the minority (median of 30% of sample). Depression reporting was heterogeneous and individuals with TBI and depression were not analyzed as a subgroup in most studies (n = 68, 55%). Depression self-report instruments are commonly used (14 instruments used in 111 studies). Few studies (n = 14, 19%) have participant samples with discrete severity levels of TBI and depression.Conclusions: Better participant representation and reporting of TBI and depression variables are needed to enhance comparability across studies and improve rehabilitation outcomes.

Mapping the occupational therapy workforce research worldwide: Study protocol for a scoping review

BACKGROUND

Human Resources for Health (HRH) research informs the development of evidence-based, population-centered HRH policies and practices. Occupational therapists are key human resources for meeting the health, rehabilitation, and occupational needs of the population worldwide. Yet, the global status of the occupational therapy workforce research remains unchartered.

OBJECTIVES

This study protocol depicts the methods to map out and synthesize the occupational therapy workforce research worldwide.

METHODS

Six scientific-literature databases and key international institutional websites will be systematically searched, complemented by snowballing searches and recommendations from key global, regional, or national representatives of the World Federation of Occupational Therapists. Two independent reviewers will screen titles-and-abstracts and then full-texts against the eligibility criteria, e.g., 10 categories of workforce research. Educational research, non-empirical papers, and papers (or their summaries) not available in English, Spanish or Portuguese are excluded. Data extraction (e.g., methods, geographies, aims, key findings) will be conducted by one author and fully verified by another. The extracted data will be computed as well as subject to content analysis to provide quantitative map of the literature and of the contents addressed, e.g., per inclusion category.

CONCLUSION

The results of this review can inform wide consultation processes and strategic, concerted local and global developments of the occupational therapy workforce.

Paramedical students' perceptions of research: a survey

BACKGROUND

There is a general perception that research is underdeveloped in rehabilitation professions. However, a PubMed search found that the growth in publications in the rehabilitation field was twice that of the general medical field. Despite this growth, another study focusing on Europe found that the proportion of articles reporting on clinical research in the rehabilitation field remained low (less than 40% of articles). This could be due to lack of teaching about research in rehabilitation schools or the late introduction of such courses.

AIMS

Describe the students' perceptions of research: their desire to conduct research, the usefulness of research and research competence.

METHODS

Questionnaire survey targeting all French paramedical students (speech therapy, occupational therapy, psychomotricity, audiometry, physiotherapy, orthoptics) in their final year of study in 2018-2019.

RESULTS

Overall, 791 students completed the full survey representing a response rate of 36.3% of the students contacted. Only 34.3% of rehabilitation students were willing to conduct research despite finding it useful (98.6%). The main barrier was the preference for their core operational work (cited 444 times, representing 17.6% of citations). There was a significant relation between perceived competence and the attractiveness of research: 84% of the students not interested in research felt they were not competent to conduct research but this figure dropped to 57.6% amongst the students interested in research (OR 4.0; 95% CI 2.9-5.6). Using a multivariate analysis, we confirmed that the main incentive was feeling competent, as well as past contact with research and supervisors who promoted research work.

CONCLUSION

Students have little contact with research during their internships, low perceived competence and, consequently, little desire to conduct research.

Scoping Review on Rehabilitation Scoping Reviews

OBJECTIVE

To examine the extent, scope, and methodological quality of rehabilitation scoping reviews.

DATA SOURCES

A comprehensive list of scoping reviews conducted in the broader health field (inception to July 2014), with a further update of that list (up to February 2017) using similar methods, including searching 9 electronic databases.

STUDY SELECTION

Articles were included if they were scoping reviews within rehabilitation. Established review methods were used including (1) a PubMed filter detecting rehabilitation content and (2) title-and-abstract screening by 2 independent reviewers applied sequentially to articles from the existing list of scoping reviews and to the updated search results. Full-text articles were reviewed by 1 reviewer, with discrepancies resolved by another after pilot screening with > 80% agreement. Remaining discrepancies were resolved by external experts.

DATA EXTRACTION

Two independent reviewers used piloted and standardized data extraction forms.

DATA SYNTHESIS

We screened 1823 records, including 992 full texts, to identify 251 rehabilitation-related scoping reviews. Rehabilitation scoping reviews had an exponential yearly increase since 2008 (r2=0.89; P<.01). The literature addressed diverse topics (eg, spread over 43 condition groupings); 43% were published in Canada. Examples of methodological limitations included: 39% of reviews did not cite the use of a methodological framework, 96% did not include the appropriate flow diagram, 8% did not report eligibility criteria, and 57% did not report data extraction details.

CONCLUSIONS

The increasing popularity of scoping reviews in rehabilitation has not been met by high standards in methodological quality. To increase the value of rehabilitation scoping reviews, rehabilitation stakeholders need to use existing methodological standards for the conduct, reporting, and appraisal of scoping reviews.

Evolving Trends in Physiotherapy Research Publications between 1995 and 2015

Purpose: The aim of this study was to comparatively analyze evolving trends in physiotherapy (PT) research publications (excluding case reports and epidemiological and qualitative studies) between 1995 and 2015, inclusively in terms of research design, funding support, age groups, and health conditions. Method: This was an observational study using PubMed-indexed data. Combinations of medical subject headings identified yearly research publications for PT and comparator fields: human-based health and physical rehabilitation. Yearly publications data were extracted, relative percentages were computed, and linear or exponential regressions examined the yearly growth in the proportion of research publications over these 2 decades. Results: As a percentage of human-based health research publications, PT research publications grew exponentially: from 0.54% in 1995 to 2.37% in 2015 (r² = 0.97; p < 0.01). As a percentage of physical rehabilitation research publications, PT research grew from 38.2% in 1995 to 58.7% in 2015 (r² = 0.89; p < 0.01). Randomized controlled trials (RCTs) resulted in the majority of PT research publications (from 45.1% in 1995 to 59.4% in 2015; r² = 0.79; p < 0.01). Rates of declared funding increased (from 29.7% in 1995 to 57% in 2015; r² = 0.83; p < 0.01), but the comparator fields had similar growth. The percentage of PT research publications remained stable for most health conditions and age groups, decreased for those aged 0-18 years (p = 0.012) and for cardiovascular and pulmonary conditions (both p < 0.01), and increased for neoplasms (p < 0.01). Conclusions: PT research publications have become more prevalent among health and physical rehabilitation research publications; the majority of publications report on RCTs.

Development of the Rehabilitation Health Policy, Systems, and Services Research field: Quantitative Analyses of Publications over Time (1990-2017) and across Country Type

BACKGROUND

Health policy, systems and services research (HPSSR) is increasingly needed to enable better access to, and value of, rehabilitation services worldwide. We aim to quantify the growth of Rehabilitation HPSSR publications since 1990, compared to that of overall rehabilitation research and overall HPSSR.

METHODS

Quantitative, comparative analysis of publication trends using the PubMed database and its indexation system. Comprehensive search filters, based on Medical Subject Headings (MeSH), were built and calibrated to locate research articles with content on HPSSR and rehabilitation of physical impairments. Additional filters were used for locating research publications declaring funding support, publications in rehabilitation journals, and finally publications focused on high-income (HICs) or low- and middle-income countries (LMICs). The same approach was used for retrieving data on comparator fields-overall HPSSR and overall rehabilitation research. Linear regressions, with ANOVA, were used for analyzing yearly publication growths over the 28-year time frame.

RESULTS

Rehabilitation HPSSR publications in PubMed have grown significantly from 1990 to 2017 in the percentage of all rehabilitation research (from 11% to 18%) and all HPSSR (from 2.8% to 3.9%; both p < 0.001). The rate of Rehabilitation HPSSR published in rehabilitation journals did not change significantly over time (p = 0.47). The rates of publications with declared funding support increased significantly, but such growth did not differ significantly from that of the comparator fields. Finally, LMICs accounted for 9.3% of the country-focused rehabilitation HPSSR since 1990, but this percentage value increased significantly (p < 0.001) from 6% in 1990 to 13% in 2017.

CONCLUSION

Rehabilitation HPSSR publications, i.e., those indexed in PubMed with related MeSH terms, have grown in both absolute and relative values. Rehabilitation HPSSR publications focused on LMICs also grew significantly since 1990, but still remained a tiny portion of the Rehabilitation HPSSR publications with country-specific MeSH terms.

Impact of economic recessions on healthcare workers and their crises' responses: study protocol for a systematic review of the qualitative and quantitative evidence for the development of an evidence-based conceptual framework

INTRODUCTION

During economic recessions, health professionals face reduced income and labour opportunities, hard conditions often exacerbated by governments' policy responses to crises. Growing evidence points to non-negligible effects on national health workforces and health systems-decrease in motivation, burnout, migration-arising from the combination of crisis-related factors. However, no theoretical conceptualisation currently exists framing the impacts recessions have on human resources for health (HRH), or on their reactions.

METHODS AND ANALYSIS

This paper lays out a protocol for a systematic review of the existing qualitative, quantitative and mixed-method evidence on the economic recessions and HRH; results from the review will be used to develop a conceptual framework linking existing theories on recessions, austerity measures, health systems and population health, with a view of informing future health policies. Eight relevant databases within the health, health systems, multidisciplinary and economic literature will be searched, complemented by secondary searches and experts' input. Eligible studies will present primary quantitative or qualitative evidence on HRH impacts, or original secondary analyses. We will cover the 1970-2019 period-the modern age of global economic recessions-and full texts in English, Spanish, Italian, French, Portuguese or Greek. Two reviewers will independently assess, perform data extraction and conduct quality appraisal of the texts identified. A 'best-fit' framework synthesis will be applied to summarise the findings, using an a priori, theoretically driven framework. That preliminary framework was built by the research team to inform the searches, and will be appraised by external experts.

ETHICS AND DISSEMINATION

In addition to peer-reviewed publications, the new framework will be presented in global health systems research conferences and inform regional policy dialogue workshops in Latin America on economic recessions and health systems.

Rehabilitation in Africa

In Africa, rehabilitation services are insufficient and marred with inadequate political commitments and collaborations of stakeholders. Infrastructures and expertise for rehabilitation are scarce and poorly coordinated. Community-based rehabilitation programs are fragmented and fractured and lack working partnership with rehabilitation services in health care systems. Locally responsive policy frameworks, service delivery models, and health governance practices are prerequisites for meeting rehabilitation needs of the ever-increasing number of persons with chronic disabling conditions. Concerted global efforts are required for equitable and accessible coordinated continuum of rehabilitation care at various levels of health services and the community in most Sub-Saharan African countries.

Global Need for Physical Rehabilitation: Systematic Analysis from the Global Burden of Disease Study 2017

Background: To inform global health policies and resources planning, this paper analyzes evolving trends in physical rehabilitation needs, using data on Years Lived with Disability (YLDs) from the Global Burden of Disease Study (GBD) 2017. Methods: Secondary analysis of how YLDs from conditions likely benefiting from physical rehabilitation have evolved from 1990 to 2017, for the world and across countries of varying income levels. Linear regression analyses were used. Results: A 66.2% growth was found in estimated YLD Counts germane to physical rehabilitation: a significant and linear growth of more than 5.1 billion YLDs per year (99% CI: 4.8–5.4; r² = 0.99). Low-income countries more than doubled (111.5% growth) their YLD Counts likely benefiting from physical rehabilitation since 1990. YLD Rates per 100,000 people and the percentage of YLDs likley benefiting from physical rehabilitation also grew significantly over time, across locations (all p > 0.05). Finally, only in high-income countries did Age-standardized YLD Rates significantly decrease (p < 0.01; r² = 0.86). Conclusions: Physical rehabilitation needs have been growing significantly in absolute, per-capita and in percentage of total YLDs. This growth was found globally and across countries of varying income level. In absolute terms, growths were higher in lower income countries, wherein rehabilitation is under-resourced, thereby highlighting important unmet needs.

Overview of reviews of standardised occupation-based instruments for use in occupational therapy practice

INTRODUCTION

Using standardised instruments is one approach to support evidence-based practice. Referring to systematic reviews is an option to identify suitable instruments. However, with an abundance of systematic reviews available, therapists are challenged to identify an appropriate instrument to use. Therefore, this overview of reviews aimed to summarise relevant systematic review findings about standardised occupation-based instruments relevant for occupational therapy practice.

METHODS

An overview of reviews was conducted. A systematic search was performed on four databases up to March 2018. Included systematic reviews were analysed for quality using A MeaSurement Tool to Assess systematic Reviews (AMSTAR).

RESULTS

A total of 2187 articles were identified after removing duplicates. Ultimately, 58 systematic reviews were identified that yielded 641 instruments. From those, 45 instruments were selected for appraisal as they met the inclusion criteria of being developed mainly by occupational therapists and were recommended in the summarised findings from the systematic reviews. The instruments were classified according to the following occupation domains: (i) multidimensional, (ii) activities of daily living, (iii) productivity, (iv) social, (v) sleep/rest, (vi) sexuality and (vii) spirituality. No systematic review was identified that specifically focussed on occupations related to school/education, leisure and play.

DISCUSSION

Certain occupation domains such as activities of daily living, social and sleep/rest received high attention amongst researchers. There is a need for systematic reviews of instruments to measure education/school, play and leisure. Limited numbers of instruments were developed by occupational therapists outside the occupation domain of activities of daily living, and in areas of practice other than children and older people. Nevertheless, this overview can give some guidance for occupational therapists in selecting a suitable occupational therapy instrument for practice.

Key Characteristics of Rehabilitation Quality Improvement Publications: Scoping Review From 2010 to 2016

OBJECTIVE

To characterize the peer-reviewed quality improvement (QI) literature in rehabilitation.

DATA SOURCES

Five electronic databases were searched for English-language articles from 2010 to 2016. Keywords for QI and safety management were searched for in combination with keywords for rehabilitation content and journals. Secondary searches (eg, references-list scanning) were also performed.

STUDY SELECTION

Two reviewers independently selected articles using working definitions of rehabilitation and QI study types; of 1016 references, 112 full texts were assessed for eligibility.

DATA EXTRACTION

Reported study characteristics including study focus, study setting, use of inferential statistics, stated limitations, and use of improvement cycles and theoretical models were extracted by 1 reviewer, with a second reviewer consulted whenever inferences or interpretation were involved.

DATA SYNTHESIS

Fifty-nine empirical rehabilitation QI studies were found: 43 reporting on local QI activities, 7 reporting on QI effectiveness research, 8 reporting on QI facilitators or barriers, and 1 systematic review of a specific topic. The number of publications had significant yearly growth between 2010 and 2016 (P=.03). Among the 43 reports on local QI activities, 23.3% did not explicitly report any study limitations; 39.5% did not used inferential statistics to measure the QI impact; 95.3% did not cite/mention the appropriate reporting guidelines; only 18.6% reported multiple QI cycles; just over 50% reported using a model to guide the QI activity; and only 7% reported the use of a particular theoretical model. Study sites and focuses were diverse; however, nearly a third (30.2%) examined early mobilization in intensive care units.

CONCLUSIONS

The number of empirical, peer-reviewed rehabilitation QI publications is growing but remains a tiny fraction of rehabilitation research publications. Rehabilitation QI studies could be strengthened by greater use of extant models and theory to guide the QI work, consistent reporting of study limitations, and use of inferential statistics.

Publication trends of study protocols in rehabilitation

INTRODUCTION

Growing evidence points for the need to publish study protocols in the health field. The aim of this paper was to observe whether the growing interest in publishing study protocols in the broader health field has been translated into increased publications of rehabilitation study protocols.

EVIDENCE ACQUISITION

PubMed was searched with appropriate combinations of Medical Subject Headings up to December 2014. The effective presence of study protocols was manually screened. Regression models analyzed the yearly growth of publications. Two-sample Z-tests analyzed whether the proportion of systematic reviews (SRs) and randomized controlled trials (RCTs) among study protocols differed from that of the same designs for the broader rehabilitation research.

EVIDENCE SYNTHESIS

Up to December 2014, 746 publications of rehabilitation study protocols were identified, with an exponential growth since 2005 (r2=0.981; P<0.001). RCT protocols were the most common among rehabilitation study protocols (83%), while RCTs were significantly more prevalent among study protocols than among the broader rehabilitation research (83% vs. 35.8%; P<0.001). For SRs, the picture was reversed: significantly less common among study protocols (2.8% vs. 9.3%; P<0.001). Funding was more often reported by rehabilitation study protocols than the broader rehabilitation research (90% vs. 53.1%; P<0.001). Rehabilitation journals published a significantly lower share of rehabilitation study protocols than they did for the broader rehabilitation research (1.8% vs.16.7%; P<0.001).

CONCLUSIONS

Identifying the reasons for these discrepancies and reverting unwarranted disparities (e.g. low rate of publication for rehabilitation SR protocols) are likely new avenues for rehabilitation research and its publication. SRs, particularly those aggregating RCT results, are considered the best standard of evidence to guide rehabilitation clinical practice; however, that standard can be improved in rigor and/or transparency if the publications of rehabilitation SRs protocols become more common.

Study protocol for a scoping review on rehabilitation scoping reviews

INTRODUCTION

Scoping reviews are increasingly popular in rehabilitation. However, significant variability in scoping review conduct and reporting currently exists, limiting potential for the methodology to advance rehabilitation research, practice and policy. Our aim is to conduct a scoping review of rehabilitation scoping reviews in order to examine the current volume, yearly distribution, proportion, scope and methodological practices involved in the conduct of scoping reviews in rehabilitation. Key areas of methodological improvement will be described. Methods and analysis: We will undertake the review using the Arksey and O'Malley scoping review methodology. Our search will involve two phases. The first will combine a previously conducted scoping review of scoping reviews (not distinct to rehabilitation, with data current to July 2014) together with a rehabilitation keyword search in PubMed. Articles found in the first phase search will undergo a full text review. The second phase will include an update of the previously conducted scoping review of scoping reviews (July 2014 to current). This update will include the search of nine electronic databases, followed by title and abstract screening as well as a full text review. All screening and extraction will be performed independently by two authors. Articles will be included if they are scoping reviews within the field of rehabilitation. A consultation exercise with key targets will inform plans to improve rehabilitation scoping reviews. Ethics and dissemination: Ethics will be required for the consultation phase of our scoping review. Dissemination will include peer-reviewed publication and conferences in rehabilitation-specific contexts.

Data Sharing and Data Registries in Physical Medicine and Rehabilitation

The field of physical medicine & rehabilitation (PM&R), along with all the disciplines it encompasses, has evolved rapidly in the past 50 years. The number of controlled trials, systematic reviews, and meta-analyses in PM&R increased 5-fold from 1998 to 2013. In recent years, professional, private, and governmental institutions have identified the need to track function and functional status across providers and settings of care and on a larger scale. Because function and functional status are key aspects of PM&R, access to and sharing of reliable data will have an important impact on clinical practice. We reviewed the current landscape of PM&R databases and data repositories, the clinical applicability and practice implications of data sharing, and challenges and future directions. We included articles that (1) addressed any aspect of function, disability, or participation; (2) focused on recovery or maintenance of any function; and (3) used data repositories or research databases. We identified 398 articles that cited 244 data sources. The data sources included 66 data repositories and 179 research databases. We categorized the data sources based on their purposes and uses, geographic distribution, and other characteristics. This study collates the range of databases, data repositories, and data-sharing mechanisms that have been used in PM&R internationally. In recent years, these data sources have provided significant information for the field, especially at the population-health level.

Human resources for health (and rehabilitation): Six Rehab-Workforce Challenges for the century

BACKGROUND

People with disabilities face challenges accessing basic rehabilitation health care. In 2006, the United Nations Convention on the Rights of Persons with Disabilities (CRPD) outlined the global necessity to meet the rehabilitation needs of people with disabilities, but this goal is often challenged by the undersupply and inequitable distribution of rehabilitation workers. While the aggregate study and monitoring of the physical rehabilitation workforce has been mostly ignored by researchers or policy-makers, this paper aims to present the 'challenges and opportunities' for guiding further long-term research and policies on developing the relatively neglected, highly heterogeneous physical rehabilitation workforce.

METHODS

The challenges were identified through a two-phased investigation. Phase 1: critical review of the rehabilitation workforce literature, organized by the availability, accessibility, acceptability and quality (AAAQ) framework. Phase 2: integrate reviewed data into a SWOT framework to identify the strengths and opportunities to be maximized and the weaknesses and threats to be overcome.

RESULTS

The critical review and SWOT analysis have identified the following global situation: (i) needs-based shortages and lack of access to rehabilitation workers, particularly in lower income countries and in rural/remote areas; (ii) deficiencies in the data sources and monitoring structures; and (iii) few exemplary innovations, of both national and international scope, that may help reduce supply-side shortages in underserved areas.

DISCUSSION

Based on the results, we have prioritized the following 'Six Rehab-Workforce Challenges': (1) monitoring supply requirements: accounting for rehabilitation needs and demand; (2) supply data sources: the need for structural improvements; (3) ensuring the study of a whole rehabilitation workforce (i.e. not focused on single professions), including across service levels; (4) staffing underserved locations: the rising of education, attractiveness and tele-service; (5) adapt policy options to different contexts (e.g. rural vs urban), even within a country; and (6) develop international solutions, within an interdependent world.

CONCLUSIONS

Concrete examples of feasible local, global and research action toward meeting the Six Rehab-Workforce Challenges are provided. Altogether, these may help advance a policy and research agenda for ensuring that an adequate rehabilitation workforce can meet the current and future rehabilitation health needs.
