Measurement Properties and Minimal Important Change of the World Health Organization Disability Assessment Schedule 2.0 in Persons With Low Back Pain: A Systematic Review.

OBJECTIVE: To determine the measurement properties and minimal important change (MIC) of the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) short (12 questions) and full (36 questions) versions in persons with nonspecific low back pain (LBP). DATA SOURCES: MEDLINE, Embase, Cumulative Index to Nursing and Allied Health Literature, APA PsycInfo, and Cochrane Central Register of Controlled Trials (inception to May 2021). STUDY SELECTION: Eligible studies assessed measurement properties or MIC of WHODAS 2.0 in persons with LBP. DATA EXTRACTION: Paired reviewers screened articles, extracted data, and assessed risk of bias using Consensus-Based Standards for Selection of Health Measurement Instruments (COSMIN) and COSMIN-Outcome Measures in Rheumatology checklists. DATA SYNTHESIS: We descriptively synthesized results stratified by measurement property and LBP duration (subacute: 6 weeks to 3 months; chronic: ≥3 months). RESULTS: We screened 297 citations and included 14 studies (reported in 15 articles). Methodological quality of studies was very good for internal consistency and varied between very good and doubtful for construct validity, doubtful for responsiveness, and adequate for all other properties assessed. Evidence suggests that WHODAS 2.0 full version has adequate content validity (2 studies); WHODAS 2.0 short and full versions have adequate structural validity (3 studies), but construct validity is indeterminate (9 studies). WHODAS 2.0 short and full versions have adequate internal consistency (10 studies), and the full version has adequate test-retest and interrater reliability (3 studies) in persons with LBP. Minimal detectable change (MDC) was 10.45-13.99 of 100 for the full version and 8.6 of 48 for the short version in persons with LBP (4 studies). WHODAS 2.0 full version has no floor or ceiling effects, but the short version has potential floor effects in persons with chronic LBP (3 studies). One study estimated MIC for the full version as 4.87 of 100 or 9.74 of 100 (corresponding to 1- and 2-point change on 0- to 10-cm visual analog scale for pain, respectively), and 1 study estimated 3.09-4.68 of 48 for the short version. CONCLUSIONS: In persons with LBP, WHODAS 2.0 full version has adequate content validity, structural validity, internal consistency, and reliability. WHODAS 2.0 short version has adequate structural validity and internal consistency. Construct validity of the short and full versions is indeterminate. Since MDC is estimated to be larger than MIC, users may consider both MIC and MDC thresholds to measure change in functioning for LBP.

Integrating Indigenous healing practices within collaborative care models in primary healthcare in Canada: a rapid scoping review.

OBJECTIVES: In November 2020, a series of reports, In Plain Sight, described widespread Indigenous-specific stereotyping, racism and discrimination limiting access to medical treatment and negatively impacting the health and wellness of Indigenous Peoples in British Columbia, Canada. To address the health inequalities experienced by Indigenous peoples, Indigenous healing practices must be integrated within the delivery of care. This rapid scoping review aimed to identify and synthesise strategies used to integrate Indigenous healing practices within collaborative care models available in community-based primary healthcare, delivered by regulated health professionals in Canada. ELIGIBILITY CRITERIA: We included quantitative, qualitative and mixed-methods studies conducted in community-based primary healthcare practices that used strategies to integrate Indigenous healing practices within collaborative care models. SOURCES OF EVIDENCE: We searched MEDLINE, Embase, Indigenous Studies Portal, Informit Indigenous Collection and Native Health Database for studies published from 2015 to 2021. CHARTING METHODS: Our data extraction used three frameworks to categorise the findings. These frameworks defined elements of integrated healthcare (ie, functional, organisational, normative and professional), culturally appropriate primary healthcare and the extent of community engagement. We narratively summarised the included study characteristics. RESULTS: We identified 2573 citations and included 31 in our review. Thirty-nine per cent of reported strategies used functional integration (n=12), 26% organisational (n=8), 19% normative (n=6) and 16% professional (n=5). Eighteen studies (58%) integrated all characteristics of culturally appropriate Indigenous healing practices into primary healthcare. Twenty-four studies (77%) involved Indigenous leadership or collaboration at each phase of the study and, seven (23%) included consultation only or the level of engagement was unclear. CONCLUSIONS: We found that collaborative and Indigenous-led strategies were more likely to facilitate and implement the integration of Indigenous healing practices. Commonalities across strategies included community engagement, elder support or Indigenous ceremony or traditions. However, we did not evaluate the effectiveness of these strategies.

Assessment of Studies Evaluating Spinal Manipulative Therapy and Infectious Disease and Immune System Outcomes: A Systematic Review.

Importance: Claims that spinal manipulative therapy (SMT) can improve immune function have increased substantially during the COVID-19 pandemic and may have contributed to the rapid spread of both accurate and inaccurate information (referred to as an infodemic by the World Health Organization). Objective: To identify, appraise, and synthesize the scientific literature on the efficacy and effectiveness of SMT in preventing the development of infectious disease or improving disease-specific outcomes in patients with infectious disease and to examine the association between SMT and selected immunological, endocrine, and other physiological biomarkers. Evidence Review: A literature search of MEDLINE, the Cumulative Index to Nursing and Allied Health Literature, the Index to Chiropractic Literature, the Cochrane Central Register of Controlled Trials, and Embase was conducted from inception to April 15, 2020. Randomized clinical trials and cohort studies were included. Eligible studies were critically appraised, and evidence with high and acceptable quality was synthesized using the Synthesis Without Meta-Analysis guideline. Findings: A total of 2593 records were retrieved; after exclusions, 50 full-text articles were screened, and 16 articles reporting the findings of 13 studies comprising 795 participants were critically appraised. The literature search found no clinical studies that investigated the efficacy or effectiveness of SMT in preventing the development of infectious disease or improving disease-specific outcomes among patients with infectious disease. Eight articles reporting the results of 6 high- and acceptable-quality RCTs comprising 529 participants investigated the effect of SMT on biomarkers. Spinal manipulative therapy was not associated with changes in lymphocyte levels or physiological markers among patients with low back pain or participants who were asymptomatic compared with sham manipulation, a lecture series, and venipuncture control groups. Spinal manipulative therapy was associated with short-term changes in selected immunological biomarkers among asymptomatic participants compared with sham manipulation, a lecture series, and venipuncture control groups. Conclusions and Relevance: In this systematic review of 13 studies, no clinical evidence was found to support or refute claims that SMT was efficacious or effective in changing immune system outcomes. Although there were limited preliminary data from basic scientific studies suggesting that SMT may be associated with short-term changes in immunological and endocrine biomarkers, the clinical relevance of these findings is unknown. Given the lack of evidence that SMT is associated with the prevention of infectious diseases or improvements in immune function, further studies should be completed before claims of efficacy or effectiveness are made.

Rehabilitative management of back pain in children: protocol for a mixed studies systematic review.

INTRODUCTION: Little is known about effective, efficient and acceptable management of back pain in children. A comprehensive and updated evidence synthesis can help to inform clinical practice. OBJECTIVE: To inform clinical practice, we aim to conduct a systematic review of the literature and synthesise the evidence regarding effective, cost-effective and safe rehabilitation interventions for children with back pain to improve their functioning and other health outcomes. METHODS AND ANALYSIS: We will search MEDLINE, Embase, PsycINFO, CINAHL, the Index to Chiropractic Literature, the Cochrane Controlled Register of Trials and EconLit for primary studies published from inception in all languages. We will include quantitative studies (randomised controlled trials, cohort and case-control studies), qualitative studies, mixed-methods studies and full economic evaluations. To augment our search of the bibliographic electronic databases, we will search reference lists of included studies and relevant systematic reviews, the WHO International Clinical Trials Registry Platform and consult with content experts. We will assess the risk of bias using appropriate critical appraisal tools. We will extract data about study and participant characteristics, intervention type and comparators, context and setting, outcomes, themes and methodological quality assessment. We will use a sequential approach at the review level to integrate data from the quantitative, qualitative and economic evidence syntheses. ETHICS AND DISSEMINATION: Ethics approval is not required. We will disseminate findings through activities, including (1) presentations in national and international conferences; (2) meetings with national and international decision makers; (3) publications in peer-reviewed journals and (4) posts on organisational websites and social media. PROSPERO REGISTRATION NUMBER: CRD42019135009.

Implementation interventions for musculoskeletal programs of care in the active military and barriers, facilitators, and outcomes of implementation: a scoping review.

BACKGROUND: Musculoskeletal disorders are common in the active military and are associated with significant lost duty days and disability. Implementing programs of care to manage musculoskeletal disorders can be challenging in complex healthcare systems such as in the military. Understanding how programs of care for musculoskeletal disorders have been implemented in the military and how they impact outcomes may help to inform future implementation interventions in this population. METHODS: We conducted a scoping review using the modified Arksey and O'Malley framework to identify literature on (1) implementation interventions of musculoskeletal programs of care in the active military, (2) barriers and facilitators of implementation, and (3) implementation outcomes. We identified studies published in English by searching MEDLINE, CINAHL, Embase, and CENTRAL (Cochrane) from inception to 1 June 2018 and hand searched reference lists of relevant studies. We included empirical studies. We synthesized study results according to three taxonomies: the Effective Practice and Organization of Care (EPOC) taxonomy to classify the implementation interventions; the capability, opportunity, motivation-behavior (COM-B) system to classify barriers and facilitators of implementation; and Proctor et al.'s taxonomy (Adm Policy Ment Health 38:65-76, 2011) to classify outcomes in implementation research. RESULTS: We identified 1785 studies and 16 were relevant. All but two of the relevant studies were conducted in the USA. Implementation interventions were primarily associated with delivery arrangements (e.g., multidisciplinary care). Most barriers or facilitators of implementation were environmental (physical or social). Service and client outcomes indicated improved efficiency of clinical care and improved function and symptomology. Studies reporting implementation outcomes indicated the programs were acceptable, appropriate, feasible, or sustainable. CONCLUSION: Identification of evidence-based approaches for the management of musculoskeletal disorders is a priority for active-duty military. Our findings can be used by military health services to inform implementation strategies for musculoskeletal programs of care. Further research is needed to better understand (1) the components of implementation interventions, (2) how to overcome barriers to implementation, and (3) how to measure implementation outcomes to improve quality of care and recovery from musculoskeletal disorders.

The Global Spine Care Initiative: a systematic review for the assessment of spine-related complaints in populations with limited resources and in low- and middle-income communities.

PURPOSE: The purpose of this systematic literature review was to develop recommendations for the assessment of spine-related complaints in medically underserved areas with limited resources. METHODS: We conducted a systematic review and best evidence synthesis of guidelines on the assessment of spine-related complaints. Independent reviewers critically appraised eligible guidelines using the Appraisal of Guidelines for Research and Evaluation-II criteria. Low risk of bias clinical practice guidelines was used to develop recommendations. In accordance with the mandate of the Global Spinal Care Initiative (GSCI), recommendations were selected that could be applied to medically underserved areas and low- and middle-income countries by considering the limited access and costs of diagnostic technologies. RESULTS: We screened 3069 citations; 20 guidelines were eligible for critical appraisal. We used 13 that had a low risk of bias that targeted neck and back pain. CONCLUSIONS: When assessing patients with spine-related complaints in medically underserved areas and low- and middle-income countries, we recommend that clinicians should: (1) take a clinical history to determine signs or symptoms suggesting serious pathology (red flags) and psychological factors (yellow flags); (2) perform a physical examination (musculoskeletal and neurological); (3) do not routinely obtain diagnostic imaging; (4) obtain diagnostic imaging and/or laboratory tests when serious pathologies are suspected, and/or presence of progressive neurologic deficits, and/or disabling persistent pain; (5) do not perform electromyography or nerve conduction studies for diagnosis of intervertebral disc disease with radiculopathy; and (6) do not perform discography for the assessment of spinal disorders. This information can be used to inform the GSCI care pathway and model of care. These slides can be retrieved under Electronic Supplementary Material.

Management of neck pain and associated disorders: A clinical practice guideline from the Ontario Protocol for Traffic Injury Management (OPTIMa) Collaboration.

PURPOSE: To develop an evidence-based guideline for the management of grades I-III neck pain and associated disorders (NAD). METHODS: This guideline is based on recent systematic reviews of high-quality studies. A multidisciplinary expert panel considered the evidence of effectiveness, safety, cost-effectiveness, societal and ethical values, and patient experiences (obtained from qualitative research) when formulating recommendations. Target audience includes clinicians; target population is adults with grades I-III NAD <6 months duration. RECOMMENDATION 1: Clinicians should rule out major structural or other pathologies as the cause of NAD. Once major pathology has been ruled out, clinicians should classify NAD as grade I, II, or III. RECOMMENDATION 2: Clinicians should assess prognostic factors for delayed recovery from NAD. RECOMMENDATION 3: Clinicians should educate and reassure patients about the benign and self-limited nature of the typical course of NAD grades I-III and the importance of maintaining activity and movement. Patients with worsening symptoms and those who develop new physical or psychological symptoms should be referred to a physician for further evaluation at any time during their care. RECOMMENDATION 4: For NAD grades I-II ≤3 months duration, clinicians may consider structured patient education in combination with: range of motion exercise, multimodal care (range of motion exercise with manipulation or mobilization), or muscle relaxants. In view of evidence of no effectiveness, clinicians should not offer structured patient education alone, strain-counterstrain therapy, relaxation massage, cervical collar, electroacupuncture, electrotherapy, or clinic-based heat. RECOMMENDATION 5: For NAD grades I-II >3 months duration, clinicians may consider structured patient education in combination with: range of motion and strengthening exercises, qigong, yoga, multimodal care (exercise with manipulation or mobilization), clinical massage, low-level laser therapy, or non-steroidal anti-inflammatory drugs. In view of evidence of no effectiveness, clinicians should not offer strengthening exercises alone, strain-counterstrain therapy, relaxation massage, relaxation therapy for pain or disability, electrotherapy, shortwave diathermy, clinic-based heat, electroacupuncture, or botulinum toxin injections. RECOMMENDATION 6: For NAD grade III ≤3 months duration, clinicians may consider supervised strengthening exercises in addition to structured patient education. In view of evidence of no effectiveness, clinicians should not offer structured patient education alone, cervical collar, low-level laser therapy, or traction. RECOMMENDATION 7: For NAD grade III >3 months duration, clinicians should not offer a cervical collar. Patients who continue to experience neurological signs and disability more than 3 months after injury should be referred to a physician for investigation and management. RECOMMENDATION 8: Clinicians should reassess the patient at every visit to determine if additional care is necessary, the condition is worsening, or the patient has recovered. Patients reporting significant recovery should be discharged.

The Effectiveness of Noninvasive Interventions for Temporomandibular Disorders: A Systematic Review by the Ontario Protocol for Traffic Injury Management (OPTIMa) Collaboration.

OBJECTIVE: To determine the effectiveness and cost-effectiveness of noninvasive interventions for temporomandibular disorders (TMD). METHODS: We systematically searched MEDLINE, EMBASE, CINAHL, PsycINFO, and Cochrane Central register from 1990 to 2014 for effectiveness studies and the Cochrane Health Technology Assessment Database, EconLit, NHS Economic Evaluation Database, and Tufts Medical Center Cost-Effectiveness Analysis Register from 1990 to 2014 for cost-effectiveness studies. Random pairs of independent reviewers critically appraised eligible studies using the Scottish Intercollegiate Guidelines Network criteria. Evidence from eligible studies was synthesized using best-evidence synthesis methodology. RESULTS: Our search for effectiveness studies yielded 16,995 citations; 31 were relevant and 7 randomized controlled trials (published in 8 articles) had a low risk of bias. We found no relevant cost-effectiveness studies. The evidence suggests that for persistent TMD: (1) cognitive-behavioral therapy and self-care management lead to similar improvements in pain and disability but cognitive-behavioral therapy is more effective for activity interference and depressive symptoms; (2) cognitive-behavioral therapy combined with usual treatment provides short-term benefits in pain and ability to control pain compared with usual treatment alone; (3) intraoral myofascial therapy may reduce pain and improve jaw opening; and (4) structured self-care management may be more effective than usual treatment. The evidence suggests that occlusal devices may not be effective in reducing pain and improving motion for TMD of variable duration. Evidence on the effectiveness of biofeedback is inconclusive. DISCUSSION: The available evidence suggests that cognitive-behavioral therapy, intraoral myofascial therapy, and self-care management are therapeutic options for persistent TMD.

Which interventions are cost-effective for the management of whiplash-associated and neck pain-associated disorders? A systematic review of the health economic literature by the Ontario Protocol for Traffic Injury Management (OPTIMa) Collaboration.

BACKGROUND CONTEXT: Whiplash-associated disorders (WAD) and neck pain and associated disorders (NAD) are prevalent conditions that impact society and impose a significant economic burden on health-care systems. Health economic evidence on WAD and NAD interventions has been sparse: only three economic evaluations of interventions for NAD were identified by the Bone and Joint Decade 2000-2010 Task Force on Neck Pain and Its Associated Disorders (NPTF). An updated overview is needed to inform health-care policy and guidelines. PURPOSE: This study aimed to determine the cost-effectiveness of interventions for grades I-III WAD and NAD in children and adults. STUDY DESIGN: Systematic review of health economic literature, best-evidence synthesis. METHODS: We systematically searched CINAHL, the Cochrane economic databases (Health Technology Assessment, NHS Economic Evaluation Database), EconLit, EMBASE, MEDLINE, PsycINFO, and Tufts CEA Registry from 2000 to 2015 for economic evaluations of WAD and NAD interventions. We appraised relevant evaluations using the Scottish Intercollegiate Guidelines Network Methodology Criteria for Economic Evaluations. We extracted data, including mean costs (standardized to 2013 Canadian dollars [CAD]) and quality-adjusted life years (QALYs), from studies with adequate methodological quality. We recalculated cost-effectiveness statistics based on the standardized currency using a willingness-to-pay of CAD $50,000 per additional QALY. Funding was provided by the Ministry of Finance. RESULTS: Our search identified 1,616 citations. Six studies fulfilled our selection criteria, including three studies previously reviewed by the NPTF. Structured education appears cost-effective for adults with WAD. For adults with NAD, acupuncture added to routine medical care; manual therapy; multimodal care that includes manual therapy; advice and exercise; and psychological care using cognitive-behavioral therapy appear cost-effective. In contrast, adding manual therapy or diathermy to advice and exercise; multimodal care by a physiotherapist or physician; and behavioral-graded activity do not appear cost-effective for adults with NAD. CONCLUSIONS: Our review adds to the findings of the NPTF. Recent evidence suggests that structured education is cost-effective for WAD, whereas advice and exercise and multimodal care that include manual therapy are cost-effective for NAD. Obtaining more robust health economic evidence for non-invasive interventions for WAD and NAD in children and adults remains an essential research priority.
