A Combined Patient and Provider Intervention for Management of Osteoarthritis in Veterans: A Randomized Clinical Trial

Utilization of telemedicine in conjunction with wearable devices for patients with chronic musculoskeletal pain: a randomized controlled clinical trial

The present randomized controlled trial aimed to investigate the effects of home-based telemedicine with wearable devices and usual care on pain-related outcomes in patients with chronic musculoskeletal pain, compared to usual care alone. The patients with chronic musculoskeletal pain were randomly allocated to the usual care group or the telemedicine group, which participated in telemedicine with wearable devices, the objective data from which were recorded, in conjunction with usual care for six months. The primary outcome measure was the Numeric Rating Scale (NRS) for pain. The secondary outcome measures were the Pain Catastrophizing Scale (PCS), Hospital Anxiety and Depression Scale (HADS), Pain Disability Assessment Scale (PDAS), and EuroQol-five dimensions-three level (EQ-5D-3L). Seventy-one participants were analyzed. At 1 and 3 months, there were no significant differences in the NRS scores between the groups; however, the telemedicine group had a significantly superior effect on all of the outcome measures at 6 months compared to the usual care group. The number of steps and distance were significantly increased at 6 months compared to baseline in the telemedicine group. Home-based telemedicine with wearable devices and usual care has a modest effect on pain-related outcomes compared to usual care in patients with chronic musculoskeletal pain.This study was registered (UMIN000052994 - 04/12/2023).

Do self-management supportive interventions reduce healthcare utilization for people with musculoskeletal pain conditions? - A systematic review

OBJECTIVE

The aim of this systematic review was to investigate the effect of self-management supportive interventions on healthcare utilization in adult cares seekers with musculoskeletal pain conditions.

STUDY DESIGN

Systematic review.

METHODS

We included studies comparing the effect of a self-management supportive intervention against a control intervention and included measures of healthcare utilization. Studies were searched in MEDLINE, Embase, PsycINFO, CINAHL, Pedro, and the Cochrane Library. Results were extracted for the follow-up point closest to 12 months. Risk of bias was assessed using the Cochrane Risk of Bias tool 2, and quality of evidence by The Grading of Recommendations Assessment, Development and Evaluation. Results were synthesized on study level as mean differences or odds ratios with 95 % CI.

RESULTS

We included 28 studies. Eighteen studies reported on the use of primary care at follow-up, and ten, four, and 13 on specialty care, diagnostics imaging, and oral pain medication, respectively. Overall, there was very low-quality evidence for no effect of self-management interventions on healthcare utilization in all groups. All studies were classified as either having a "high risk of bias" or "some concerns".

CONCLUSION

Due to substantial heterogeneity in the types and measurement of healthcare utilization outcomes, it was not feasible to conduct a meta-analysis to estimate an overall effect size. A standardized way of reporting and measuring these outcomes could aid future research in this area. The current evidence suggests that self-management supportive interventions do not affect healthcare utilization in people with musculoskeletal pain conditions, but future high-quality studies may substantially change this conclusion.

A randomized clinical trial testing digital mindset intervention for knee osteoarthritis pain and activity improvement

This randomized clinical trial evaluated the effectiveness of short, digital interventions in improving physical activity and pain for individuals with knee osteoarthritis. We compared a digital mindset intervention, focusing on adaptive mindsets (e.g., osteoarthritis is manageable), to a digital education intervention and a no-intervention group. 408 participants with knee osteoarthritis completed the study online in the US. The mindset intervention significantly improved mindsets compared to both other groups (P < 0.001) and increased physical activity levels more than the no-intervention group (mean = 28.6 points, P = 0.001), but pain reduction was not significant. The mindset group also showed significantly greater improvements in the perceived need for surgery, self-imposed physical limitations, fear of movement, and self-efficacy than the no-intervention and education groups. This trial demonstrates the effectiveness of brief digital interventions in educating about osteoarthritis and further highlights the additional benefits of improving mindsets to transform patients' approach to disease management. The study was prospectively registered (ClinicalTrials.gov: NCT05698368, 2023-01-26).

Which Remote Rehabilitation Interventions Work Best for Chronic Musculoskeletal Pain and Depression? A Bayesian Network Meta-Analysis

OBJECTIVE: To evaluate the effectiveness of remote rehabilitation interventions for people living with chronic musculoskeletal pain and depression. DESIGN: A systematic review with network meta-analysis (NMA) of randomized controlled trials. LITERATURE SEARCH: We searched the Cochrane Central Register of Controlled Trials, CINAHL, EMBASE, LILACS MEDLINE, PSYNDEX, and PsycINFO databases from inception to May 2023. STUDY SELECTION CRITERIA: Randomized controlled trials that evaluated the effectiveness of remote rehabilitation interventions in people with chronic musculoskeletal pain and depression. DATA SYNTHESIS: We used Bayesian random-effects models for the NMA. Effect estimates were comparisons between rehabilitation interventions and waitlist. We performed a sensitivity analysis based on bias in the randomization process, large trials (>100 patients per arm) and musculoskeletal condition. RESULTS: Fifty-eight randomized controlled trials involving 10 278 participants (median sample size: 137; interquartile range [IQR]: 77-236) were included. Interactive voice response cognitive behavioral therapy (CBT; standardized mean difference [SMD] -0.66, 95% credible interval [CrI] -1.17 to -0.16), CBT in person (SMD -0.50, 95% CrI -0.97 to -0.04), and mobile app CBT plus exercise (SMD -0.37, 95% CrI -0.69 to -0.02) were superior to waitlist at 12-week follow-up for reducing pain (> 98% probability of superiority). For depression outcomes, Internet-delivered CBT and telecare were superior to waitlist at 12-week follow-up (SMD -0.51, 95% CrI -0.87 to -0.13) (> 99% probability of superiority). For pain outcomes, the certainty of evidence ranged from low to moderate. For depression outcomes, the certainty of evidence ranged from very low to moderate. The proportion of dropouts attributed to adverse events was unclear. No intervention was associated with higher odds of dropout. CONCLUSION: Interactive voice response CBT and mobile app CBT plus exercise showed similar treatment effects with in-person CBT on pain reduction among people living with chronic musculoskeletal pain and depression had over 98% probability of superiority than waitlist control at 12-week follow-up. Internet-delivered CBT and telecare had over 99% probability of superiority than waitlist control for improving depression outcomes at 12-week follow-up. J Orthop Sports Phys Ther 2024;54(6):1-16.

Self-Care Education on the Pain, Quality of Life, and Consequences of Disease in Patients with Knee Osteoarthritis

Introduction

Knee osteoarthritis (KOA) is one of the most common and prevalent debilitating chronic diseases across the world with various adverse effects such as pain and movement limitations which impact the health status and quality of life of the patients in the long run.

Objectives

This study aimed to investigate the effects of self-care education on pain, quality of life, and consequences of disease in patients with KOA in Southern Iran.

Methods

This is a randomized controlled clinical trial using a pretest-posttest design. Eighty patients with KOA were enrolled in this study and randomly allocated to a control and an intervention group. The data collection instruments included VAS: Visual Analog Scale, the SF-36 quality of life scale, and the Knee Injury and Osteoarthritis Outcome Score. The collected data were analyzed through SPSS v. 22, using descriptive tests, paired t-tests, independent t-tests, Chi-square, and ANOVA. A P level of <.05 was considered as the significant level.

Results

Before the self-care educational intervention, no statistically significant difference was found between the control and intervention groups in pain intensity, quality of life, and consequences of osteoarthritis. After the self-care educational intervention, the findings revealed a significant difference between the intervention group's mean ± standard deviation for pain intensity (41.25 ± 21.74), quality of life (49.87 ± 14.74), and consequences of KOA (39.06 ± 12.15), respectively (P < .05). However, in the control group, there was no significant difference.

Conclusion

Based on the results of this study, the positive effect of self-care education on patients with osteoarthritis was shown as to their pain intensity, quality of their lives, and reduction of the disease consequences. Thus, healthcare managers are recommended to apply this type of intervention for patients with osteoarthritis.

The efficacy of telephone-delivered cognitive behavioral therapy in people with chronic illnesses and mental diseases: A meta-analysis

COVID-19 pandemic led to an increase of remote treatments, such as telephone-delivery cognitive behavioral therapy (T-CBT). To our knowledge, no meta-analyses studied the effect of T-CBT in chronic and/or mental illnesses on multiple psychological outcomes. Therefore, our study aims to evaluating the efficacy of T-CBT compared to other interventions (treatment as usual, TAU, or face-to-face CBT). Each effect size (ES) was calculated in Hedges' g and pooled together to produce a mean ES for each outcome (depression, anxiety, mental and physical QoL, worry, coping, and sleep disturbances). The meta-analysis included 33 studies with a randomized controlled trial design. A large ES was found when comparing the efficacy of T-CBT against TAU on depression (g = 0.84, p < 0.001), whereas a moderate ES was found on anxiety (g = 0.57; p < 0.001), and a small effect on mental quality of life (g = 0.33, p < 0.001), sleep disturbances (g = 0.37, p = 0.042), coping (g = 0.20, p = 0.016) and worry (g = 0.43, p = 0.001). The meta-analysis comparing the efficacy of T-CBT and CBT on depression revealed a not significant pooled ES (g = 0.06, p = 0.466). The results provided evidence that T-CBT could be to be more effective than TAU conditions in multiple psychological outcomes, and as efficient as face-to-face CBT in treating depression.

Intracluster correlation coefficients in osteoarthritis cluster randomized trials: A systematic review

OBJECTIVES

The design, analysis, and interpretation of cluster randomized clinical trials (RCTs) require accounting for potential correlation of observations on individuals within the same cluster. Reporting of observed intracluster correlation coefficients (ICCs) in cluster RCTs, as recommended by Consolidated Standards of Reporting Trials (CONSORT), facilitates sample size calculation of future cluster RCTs and understanding of the trial statistical power. Our objective was to summarize observed ICCs in osteoarthritis (OA) cluster RCTs.

DESIGN

Systematic review of knee/hip OA cluster RCTs. We searched Cochrane Central Register of Controlled Trials for trials published from 2012, when CONSORT cluster RCTs extension was published, to September 2022. We calculated the proportion of cluster RCTs that reported observed ICCs. Of those that did, we extracted observed ICCs.

PROSPERO

CRD42022365660.

RESULTS

We screened 1121 references and included 20 cluster RCTs. Only 5 trials (25%) reported the observed ICC for at least one outcome variable. ICC values for pain outcomes were: 0, 0.01, 0.18; for physical function outcomes were: 0, 0.06, 0.13 (knee)/0.27 (hip); Western Ontario and McMaster Universities Arthritis Index (WOMAC) total: 0.02, 0.02; symptoms of anxiety/depression: 0.22; disability: 0; and global change: 0. One out of four (25%) trials reported an ICC that was larger than the ICC used for sample size calculation and thus was underpowered.

CONCLUSIONS

Despite CONSORT statement recommendations for reporting cluster RCTs, few OA trials reported the observed ICC. Given the importance of the ICC to interpretation of trial results and future trial design, this reporting gap warrants attention.

Primary care-based models of care for osteoarthritis; a scoping review

OBJECTIVE

To identify and describe the extent, nature, characteristics, and impact of primary care-based models of care (MoCs) for osteoarthritis (OA) that have been developed and/or evaluated.

DESIGN

Six electronic databases were searched from 2010 to May 2022. Relevant data were extracted and collated for narrative synthesis.

RESULTS

Sixty-three studies pertaining to 37 discrete MoCs from 13 countries were included, of which 23 (62%) could be classified as OA management programmes (OAMPs) comprising a self-management intervention to be delivered as a discrete package. Four models (11%) focussed on enhancing the initial consultation between a patient presenting with OA at the first point of contact into a local health system and the clinician. Emphasis was placed on educational training for general practitioners (GPs) and allied healthcare professionals delivering this initial consultation. The remaining 10 MoCs (27%) detailed integrated care pathways of onward referral to specialist secondary orthopaedic and rheumatology care within local healthcare systems. The majority (35/37; 95%) were developed in high-income countries and 32/37 (87%) targeted hip/and or knee OA. Frequently identified model components included GP-led care, referral to primary care services and multidisciplinary care. The models were predominantly 'one-size fits all' and lacked individualised care approaches. A minority of MoCs, 5/37 (14%) were developed using underlying frameworks, three (8%) of which incorporated behaviour change theories, while 13/37 (35%) incorporated provider training. Thirty-four of the 37 models (92%) were evaluated. Outcome domains most frequently reported included clinical outcomes, followed by system- and provider-level outcomes. While there was evidence of improved quality of OA care associated with the models, effects on clinical outcomes were mixed.

CONCLUSION

There are emerging efforts internationally to develop evidence-based models focused on non-surgical primary care OA management. Notwithstanding variations in healthcare systems and resources, future research should focus on model development alignment with implementation science frameworks and theories, key stakeholder involvement including patient and public representation, provision of training and education for providers, treatment individualisation, integration and coordination of services across the care continuum and incorporation of behaviour change strategies to foster long-term adherence and self-management.

A single-center, open-label, randomized, parallel-group trial to pilot the effectiveness of a peer coach behavioral intervention versus an active control in reducing anxiety and depression in patients scheduled for total knee replacement

BACKGROUND

Moving Well is a behavioral intervention for patients with knee osteoarthritis (KOA) scheduled for a total knee replacement (TKR). The objective of this intervention is to help patients with KOA mentally and physically prepare for and recover from TKR.

METHODS

This is an open-label pilot randomized clinical trial that will test the feasibility and effectiveness of the Moving Well intervention compared to an attention control group, Staying Well, to reduce symptoms of anxiety and depression in patients with KOA undergoing TKR. The Moving Well intervention is guided by Social Cognitive Theory. During this 12-week intervention, participants will receive 7 weekly calls before surgery and 5 weekly calls after surgery from a peer coach. During these calls, participants will be coached to use principles of cognitive behavioral therapy (CBT), stress reduction techniques, and will be assigned an online exercise program, and self-monitoring activities to complete on their own time throughout the program. Staying Well participants will receive weekly calls of similar duration from research staff to discuss a variety of health topics unrelated to TKR, CBT, or exercise. The primary outcome is the difference in levels of anxiety and/or depression between participants in the Moving Well and Staying Well groups 6 months after TKR.

DISCUSSION

This study will pilot test the feasibility and effectiveness of Moving Well, a peer coach intervention, alongside principles of CBT and home exercise, to help patients with KOA mentally and physically prepare for and recover from TKR.

Virtual Tools to Enable Management of Knee Osteoarthritis

Purpose of review

There is increasing recognition that virtual tools, enabled by the internet and telecommunications technology, can increase access to health care. We review evidence about the clinical effectiveness and acceptability of telephone-delivered and videoconferencing clinician consultations, websites and internet-delivered programs, and SMS and mobile applications in enabling the management of people with knee osteoarthritis (OA). We discuss barriers to using virtual tools and suggest strategies to facilitate implementation in clinical settings.

Recent findings

An increasing number of systematic reviews, meta-analyses, and clinical trials provide evidence showing the effectiveness of virtual tools for improving knee OA management. Qualitative research shows that virtual tools increase patient access to knee OA care, are generally acceptable and convenient for patients, but can be associated with barriers to use from patient and clinician perspectives.

Summary

Virtual tools offer new opportunities to enable people with knee OA to manage their condition and receive care that may otherwise be difficult or not possible to access. Telephone calls and videoconferencing can be used for real-time synchronous consultations between clinicians and patients, increasing the geographic reach of health services. Websites and internet-based programs can be used to educate patients about their condition, as well as deliver exercise, weight management, and psychological interventions. Mobile apps can monitor and track OA symptoms, exercise, and physical activity, while SMS can facilitate positive behaviour changes for self-management over the long-term when sustained clinician contact may not be possible.

Long-Term Clinical Outcomes of a Remote Digital Musculoskeletal Program: An Ad Hoc Analysis from a Longitudinal Study with a Non-Participant Comparison Group

Digital solutions have emerged as an alternative to conventional physiotherapy, particularly for chronic musculoskeletal pain (CMP) management; however, its long-term effects remain largely unexplored. This study focuses on patients reporting CMP, assessing 1-year clinical outcomes after a multimodal digital care program (DCP) versus non-participants, who enrolled in the program but never engaged in a single exercise session or partook of the educational content made available to them. In this longitudinal study ad-hoc analysis, pain and functionality outcomes at 1-year reassessment were studied, focusing on the odds of reaching minimal clinically important difference (MCID) and, overall average reduction in both outcomes. Healthcare utilization was additionally studied within the same period. From 867 individuals allocated to the study, 460 completed the 1-year reassessment (intervention group: 310; comparison group: 150). The intervention group presented sustained and greater pain reduction until 1-year reassessment than the comparison group, reflecting greater odds ratio of achieving the MCID both in pain and functionality (1.90 95% CI: 1.27-2.86, p = 0.002 and 2.02 95% CI: 1.31-3.12, p = 0.001, respectively). A lower healthcare utilization during the 1-year follow-up was observed in the intervention group than in the comparison group. This study suggests that a digital CMP program may have a lasting impact on improved pain and functionality in patients with CMP.

Digital Care Programs for Chronic Hip Pain: A Prospective Longitudinal Cohort Study

Chronic hip pain is a cause of disability worldwide. Digital interventions (DI) may promote access while providing proper management. This single-arm interventional study assesses the clinical outcomes and engagement of a completely remote multimodal DI in patients with chronic hip pain. This home-based DI consisted of exercise (with real-time biofeedback), education, and cognitive-behavioral therapy. Outcomes were calculated between baseline and program end, using latent growth curve analysis. Primary outcome was the Hip Disability and Osteoarthritis Outcome Score (HOOS). Secondary outcomes were pain, intent to undergo surgery, mental health, productivity, patient engagement (exercise sessions frequency), and satisfaction. Treatment response was assessed using a 30% pain change cut-off. A completion rate of 74.2% (396/534), alongside high patient engagement (2.9 exercise sessions/week, SD 1.1) and satisfaction (8.7/10, SD 1.6) were observed. Significant improvements were observed across all HOOS sub-scales (14.7−26.8%, p < 0.05), with 66.8% treatment responders considering pain. Marked improvements were observed in surgery intent (70.1%), mental health (54%), and productivity impairment (60.5%) (all p < 0.001). The high engagement and satisfaction reported after this DI, alongside the clinical outcome improvement, support the potential of remote care in the management of chronic hip conditions.

Knee Osteoarthritis Education Interventions in Published Trials Are Typically Unclear, Not Comprehensive Enough, and Lack Robust Development: Ancillary Analysis of a Systematic Review

OBJECTIVE

To summarize the content, development, and delivery of education interventions in clinical trials for people with knee osteoarthritis (OA).

DESIGN

Ancillary analysis of a systematic review.

LITERATURE SEARCH

MEDLINE, EMBASE, SPORTDiscus, CINAHL, and Web of Science were searched from inception to April 2020.

STUDY SELECTION CRITERIA

Randomized controlled trials involving patient education for people with knee OA.

DATA SYNTHESIS

Content of education interventions was matched against a predefined topic list (n = 14) and categorized as accurate and clear, partially accurate/lacks clarity, or not reported. We examined whether education interventions included skill development or stated learning objectives and if they were developed based on theory, previous research, or codesign principles. Delivery methods and mode(s) were also identified. Data were summarized descriptively.

RESULTS

Thirty-eight education interventions (30 trials) were included. Interventions lacked comprehensiveness (median topics per intervention = 3/14, range = 0-11). Few topics were accurately and clearly described (10%, 13/136). Sixty-one percent (n = 23/38) of interventions targeted skill development, and 34% (n = 13/38) identified learning objectives. Forty-two percent (n = 16/38) were based on theory; 45% (n = 17/38) were based on research for chronic conditions, including 32% (n = 12/38) based on OA. Eleven percent of interventions (n = 4/38) were codesigned. Education was typically facilitated through face-to-face sessions (median = 9, range = 0-55), supplemented with telephone calls and/or written materials.

CONCLUSION

Education interventions for people with knee OA lacked comprehensiveness plus accurate and clear descriptions of topics covered. Most interventions failed to identify learning objectives and were not based on theory, previous research, or codesign principles. J Orthop Sports Phys Ther 2022;52(5):276-286.

Cost and Quality of Life Outcomes of the STepped Exercise Program for Patients With Knee OsteoArthritis Trial

OBJECTIVES

This study aimed to evaluate the cost-effectiveness of the randomized clinical trial STEP-KOA (STepped Exercise Program for patients with Knee OsteoArthritis).

METHODS

The trial included 230 intervention and 115 control participants from 2 Veterans Affairs (VA) medical centers. A decision tree simulated outcomes for cohorts of patients receiving arthritis education (control) or STEP-KOA (intervention), which consisted of an internet-based exercise training program (step 1), phone counseling (step 2), and physical therapy (step 3) according to patient's response. Intervention costs were assessed from the VA perspective. Quality of life (QOL) was measured using 5-level EQ-5D US utility weights. Incremental cost-effectiveness ratios (ICERs) were calculated as the difference in costs divided by the difference in quality-adjusted life-years (QALYs) between arms at 9 months. A Monte Carlo probabilistic sensitivity analysis was used to generate a cost-effectiveness acceptability curve.

RESULTS

The adjusted model found differential improvement in QOL utility weights of 0.042 (95% confidence interval 0.003-0.080; P=.03) for STEP-KOA versus control at 9 months. In the base case, STEP-KOA resulted in an incremental gain of 0.028 QALYs and an incremental cost of $279 per patient for an ICER of $10 076. One-way sensitivity analyses found the largest sources of variation in the ICER were the impact on QOL and the need for a VA-owned tablet. The probabilistic sensitivity analysis found a 98% probability of cost-effectiveness at $50 000 willingness-to-pay per QALY.

CONCLUSIONS

STEP-KOA improves QOL and has a high probability of cost-effectiveness. Resources needed to implement the program will decline as ownership of mobile health devices increases.

Effects of physical exercise and body weight on disease-specific outcomes of people with rheumatic and musculoskeletal diseases (RMDs): systematic reviews and meta-analyses informing the 2021 EULAR recommendations for lifestyle improvements in people with RMDs

BACKGROUND

A European League Against Rheumatism (EULAR) taskforce was convened to develop recommendations for lifestyle behaviours in rheumatic and musculoskeletal diseases (RMDs). This paper reviews the literature on the effects of physical exercise and body weight on disease-specific outcomes of people with RMDs.

METHODS

Three systematic reviews were conducted to summarise evidence related to exercise and weight in seven RMDs: osteoarthritis, rheumatoid arthritis, systemic lupus erythematosus, axial spondyloarthritis (axSpA), psoriatic arthritis, systemic sclerosis and gout. Systematic reviews and original studies were included if they assessed exercise or weight in one of the above RMDs, and reported results regarding disease-specific outcomes (eg, pain, function, joint damage). Systematic reviews were only included if published between 2013-2018. Search strategies were implemented in the Medline, Embase, Cochrane Library of systematic reviews and CENTRAL databases.

RESULTS

236 articles on exercise and 181 articles on weight were included. Exercise interventions resulted in improvements in outcomes such as pain and function across all the RMDs, although the size of the effect varied by RMD and intervention. Disease activity was not influenced by exercise, other than in axSpA. Increased body weight was associated with worse outcomes for the majority of RMDs and outcomes assessed. In general, study quality was moderate for the literature on exercise and body weight in RMDs, although there was large heterogeneity between studies.

CONCLUSION

The current literature supports recommending exercise and the maintenance of a healthy body weight for people with RMDs.

Are Nonpharmacologic Interventions Delivered Through Synchronous Telehealth as Effective and Safe as In-Person Interventions for the Management of Patients With Nonacute Musculoskeletal Conditions? A Systematic Rapid Review

OBJECTIVE

To determine whether nonpharmacologic interventions delivered through synchronous telehealth are as effective and safe compared with in-person interventions for the management of patients with musculoskeletal conditions in improving pain, functioning, self-reported recovery, psychological outcomes, or health-related quality of life using rapid review methods.

DATA SOURCES

We searched MEDLINE, CINAHL, Embase, and Cochrane Central Register of Controlled Trials from 2010 to August 2020 for randomized controlled trials (RCTs) published in English or French; we updated our search in January 2021.

STUDY SELECTION

One reviewer screened citations in 2 phases (phase 1: title/abstract; phase 2: full-text) selecting RCTs comparing synchronous telehealth with in-person care for the management of musculoskeletal conditions. A random 10% sample was screened by 2 independent reviewers with minimum 95% agreement prior to full screening. One reviewer critically appraised and one reviewer validated appraisal for eligible RCTs.

DATA EXTRACTION

One author extracted participant characteristics, setting, sample size, interventions, comparisons, follow-up period, and outcome data. A second author validated data extraction.

DATA SYNTHESIS

We summarized the findings narratively. Low- to moderate-quality evidence suggests that synchronous telehealth (ie, videoconference or telephone calls) alone or in combination with in-person care leads to similar outcomes as in-person care alone for nonspecific low back pain, generalized osteoarthritis, hip or knee osteoarthritis, and nonacute headaches in adults.

CONCLUSIONS

Synchronous telehealth may be an option for the management of nonacute musculoskeletal conditions in adults. However, our results may not be generalizable to rural or low socioeconomic populations. Future research should investigate the outcomes associated the use of new technologies, such as videoconference.

Accelerating Implementation of Virtual Care in an Integrated Health Care System: Future Research and Operations Priorities

BACKGROUND

Virtual care is critical to Veterans Health Administration (VHA) efforts to expand veterans' access to care. Health care policies such as the Veterans Access, Choice, and Accountability (CHOICE) Act and the Maintaining Internal Systems and Strengthening Integrated Outside Networks (MISSION) Act impact how the VHA provides care. Research on ways to refine virtual care delivery models to meet the needs of veterans, clinicians, and VHA stakeholders is needed.

OBJECTIVE

Given the importance of virtual approaches for increasing access to high-quality VHA care, in December 2019, we convened a Think Tank, Accelerating Implementation of Virtual Care in VHA Practice, to consider challenges to virtual care research and practice across the VHA, discuss novel approaches to using and evaluating virtual care, assess perspectives on virtual care, and develop priorities to enhance virtual care in the VHA.

METHODS

We used a participatory approach to develop potential priorities for virtual care research and activities at the VHA. We refined these priorities through force-ranked prioritization and group discussion, and developed solutions for selected priorities.

RESULTS

Think Tank attendees (n = 18) consisted of VHA stakeholders, including operations partners (e.g., Office of Rural Health, Office of Nursing Services, Health Services Research and Development), clinicians (e.g., physicians, nurses, psychologists, physician assistants), and health services researchers. We identified an initial list of fifteen potential priorities and narrowed these down to four. The four priorities were (1) scaling evidence-based practices, (2) centralizing virtual care, (3) creating high-value care within the VHA with virtual care, and (4) identifying appropriate patients for virtual care.

CONCLUSION

Our Think Tank took an important step in setting a partnered research agenda to optimize the use of virtual care within the VHA. We brought together research and operations stakeholders and identified possibilities, partnerships, and potential solutions for virtual care.

Patient education improves pain and function in people with knee osteoarthritis with better effects when combined with exercise therapy: a systematic review

QUESTION

Is patient education effective as a standalone intervention or combined with other interventions for people with knee osteoarthritis?

DESIGN

Systematic review of randomised controlled trials. MEDLINE, EMBASE, SPORTDiscus, CINAHL and Web of Science were searched from inception to April 2020. The Cochrane Risk of Bias tool was used for included studies, and Grading of Recommendations, Assessment, Development and Evaluations (GRADE) was used to interpret certainty of results.

PARTICIPANTS

People with knee osteoarthritis.

INTERVENTION

Any patient education intervention compared with any non-pharmacological comparator.

OUTCOME MEASURES

Primary outcomes were self-reported pain and function.

RESULTS

Twenty-nine trials involving 4,107 participants were included, informing low to very-low certainty evidence. Nineteen of 28 (68%) pooled comparisons were not statistically significant. Patient education was superior to usual care for pain (SMD -0.35, 95% CI -0.56 to -0.14) and function in the short term (-0.31, 95% CI -0.62 to 0.00), but inferior to exercise therapy for pain in the short term (0.77, 95% CI 0.07 to 1.47). Combining patient education with exercise therapy produced superior outcomes compared with patient education alone for pain in the short term (0.44, 95% CI 0.19 to 0.69) and function in the short (0.81, 95% CI 0.54 to 1.08) and medium term (0.39, 95% CI 0.15 to 0.62). When using the Western Ontario and McMaster Universities Osteoarthritis Index for these comparisons, clinically important differences indicated that patient education was inferior to exercise therapy for pain in the short term (MD 1.56, 95% CI 0.14 to 2.98) and the combination of patient education and exercise therapy for function in the short term (8.94, 95% CI 6.05 to 11.82).

CONCLUSION

Although patient education produced statistically superior short-term pain and function outcomes compared with usual care, differences were small and may not be clinically important. Patient education should not be provided as a standalone treatment and should be combined with exercise therapy to provide statistically superior and clinically important short-term improvements in function compared with education alone.

Stepped-down intervention programs to promote self-managed physical activity in military service veterans: A systematic review of randomised controlled trials

OBJECTIVES

A stepped-down program is one where clients transition from the care of a health professional to self-managed care. This study reviewed the effectiveness of stepped-down interventions to promote self-managed physical activity for health in military service veterans.

DESIGN

Systematic review.

METHODS

Literature searches of 11 electronic databases were performed (up to 28th April 2020) to identify randomised controlled trials that assessed self-managed physical activity interventions in military service veterans. Data were extracted on study characteristics, intervention programs (with strategies mapped against a taxonomy of behaviour change techniques), and physical activity outcomes; secondary outcomes were physical fitness/function, psychosocial health, and cost effectiveness. Study quality was assessed using a 15-item checklist adapted from the TESTEX scale.

RESULTS

Searches identified 26 studies (all from the United States; N = 45 to 531 participants) representing 17 intervention programs. Studies were of good quality (M = 10.7; SD = 2.3). More than half (54%) reported positive between-group intervention effects for physical activity outcomes (mean increase of 80 min/week in self-reported physical activity at 10-12 months). Physical fitness/function outcomes improved in 38% of studies, but no studies found significant intervention effects for psychosocial health or cost effectiveness outcomes. Behaviour change techniques most frequently used to elicit physical activity changes were education, goal setting, goal review and self-monitoring.

CONCLUSIONS

Stepped-down programs that include specific behaviour change techniques have the potential to promote self-management of physical activity in military service veterans. Multi-national randomised controlled trials that use objective physical activity measures are needed to further build the evidence base.

microRNA-130b downregulation potentiates chondrogenic differentiation of bone marrow mesenchymal stem cells by targeting SOX9

Osteoarthritis (OA) is a chronic health condition. MicroRNAs (miRs) are critical in chondrocyte apoptosis in OA. We aimed to investigate the mechanism of miR-130b in OA progression. Bone marrow mesenchymal stem cells (BMSCs) and chondrocytes were first extracted. Chondrogenic differentiation of BMSCs was carried out and verified. Chondrocytes were stimulated with interleukin (IL)-1β to imitate OA condition in vitro. The effect of miR-130b on the viability, inflammation, apoptosis, and extracellular matrix of OA chondrocytes was studied. The target gene of miR-130b was predicted and verified. Rescue experiments were performed to further study the underlying downstream mechanism of miR-130b in OA. miR-130b first increased and drastically reduced during chondrogenic differentiation of BMSCs and in OA chondrocytes, respectively, while IL-1β stimulation resulted in increased miR-130b expression in chondrocytes. miR-130b inhibitor promoted chondrogenic differentiation of BMSCs and chondrocyte growth and inhibited the levels of inflammatory factors. miR-130b targeted SOX9. Overexpression of SOX9 facilitated BMSC chondrogenic differentiation and chondrocyte growth, while siRNA-SOX9 contributed to the opposite trends. Silencing of SOX9 significantly attenuated the pro-chondrogenic effects of miR-130b inhibitor on BMSCs. Overall, miR-130b inhibitor induced chondrogenic differentiation of BMSCs and chondrocyte growth by targeting SOX9.

Are PROMs used adequately in sports research? An analysis of 54 randomized controlled trials with PROMs as endpoint

Deviations from adequate use and reporting of PROMs may be problematic and misleading. The aim of this study was to investigate the extent of such problems in randomized clinical trials (RCTs). RCTs involving sports medicine research that used PROMs as primary outcomes were identified in 13 preselected journals. The articles were reviewed for nine potential problems related to how the PROM was used and how the data had been reported. The potential problems were as follows: aggregating subscale scores; combining patient-reported scores with physical, clinical, or para-clinical measures; using a PROM to diagnose or evaluate the individual patient; using a PROM for one leg or arm; selectively excluding domains or items; constructing a PROM for the specific occasion; mixing PROM formats (ie, digital, paper, telephone, e-mail, in person); ambiguous instructions for how the PROM should be completed; and recall bias. As covariates, we registered journal impact factor, year of publication, and existence of a registered protocol. In 29 (53.7%) of 54 identified RCTs, at least one potential problem was identified, the most common being aggregation of domain scores. This was not different with a published protocol or dependent on journal rankings, except for exclusion of domains, which was most common in high-ranking journals. Aggregation of domain scores was significantly less common in recently published articles compared with older articles (P = .03). Potential problematic use of PROMs and reporting of PROM data are common in RCTs, also in high-ranking journals, but less so in more recent articles.

Effectiveness of exercises by telerehabilitation on pain, physical function and quality of life in people with physical disabilities: a systematic review of randomised controlled trials with GRADE recommendations

OBJECTIVE

Investigate whether exercise-based telerehabilitation improves pain, physical function and quality of life in adults with physical disabilities.

DESIGN

Systematic review of randomised controlled trials.

DATA SOURCES

Searches were performed in AMED, MEDLINE, CINAHL, SPORTDiscus, Embase, PEDro, Cochrane Library and PsycINFO.

ELIGIBILITY CRITERIA

Trials were considered if they evaluated exercise by telerehabilitation. The population included adults with physical disability. Comparisons were control and other interventions. The outcomes were pain, physical function and quality of life. Study selection, data extraction and analysis followed the protocol registered in PROSPERO (CRD42019122824). GRADE determined the strength of evidence.

RESULTS

Forty-eight trials were included in the quantitative analysis. When compared with other interventions, there was high-quality evidence that telerehabilitation was not different to other interventions for pain (95% CI: -0.4 to 0.1), physical function (95% CI: -0.2 to 0.2) and quality of life (95% CI: -0.1 to 0.5) at long-term. There was moderate-quality evidence that telerehabilitation was not different to other interventions for physical function (95% CI: -0.1 to 0.5) and quality of life (95% CI: -0.2 to 0.5) at short-term. However, due to the low-quality evidence and the small number of trials comparing exercise protocols offered by telerehabilitation with control groups, it is still not possible to state the efficacy of telerehabilitation on pain, function and quality of life at short-term and long-term.

CONCLUSIONS

Exercise by telerehabilitation may be an alternative to treat pain, physical function and quality of life in adults with physical disabilities when compared with other intervention.

Digital Self-Management Interventions for People With Osteoarthritis: Systematic Review With Meta-Analysis

BACKGROUND

Osteoarthritis (OA) is not curable, but the symptoms can be managed through self-management programs (SMPs). Owing to the growing burden of OA on the health system and the need to ensure high-quality integrated services, delivering SMPs through digital technologies could be an economic and effective community-based approach.

OBJECTIVE

This study aims to analyze the effectiveness of digital-based structured SMPs on patient outcomes in people with OA.

METHODS

A total of 7 web-based and 3 gray literature databases were searched for randomized controlled trials assessing digital-based structured SMPs on self-reported outcomes including pain, physical function, disability, and health-related quality of life (QoL) in people with OA. Two reviewers independently screened the search results and reference lists of the identified papers and related reviews. Data on the intervention components and delivery and behavioral change techniques used were extracted. A meta-analysis, risk of bias sensitivity analysis, and subgroup analysis were performed where appropriate. The Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) approach was used to assess the quality of evidence.

RESULTS

A total of 8 studies were included in this review involving 2687 patients with knee (n=2); knee, hip, or both (n=5); and unspecified joint (n=1) OA. SMPs were delivered via telephone plus audio and video, internet, or mobile apps. Studies reported that digital-based structured SMPs compared with the treatment as usual control group (n=7) resulted in a significant, homogeneous, medium reduction in pain and improvement in physical function (standardized mean difference [SMD] -0.28, 95% CI -0.38 to -0.18 and SMD -0.26, 95% CI -0.35 to -0.16, respectively) at posttreatment. The digital-based structured SMP effect on pain and function reduced slightly at the 12-month follow-up but remained to be medium and significant. The posttreatment effect of digital-based structured SMPs was small and significant for disability, but nonsignificant for QoL (SMD -0.10, 95% CI -0.17 to 0.03 and SMD -0.17, 95% CI -0.47 to 0.14, respectively; each reported in 1 study only). The 12-month follow-up effect of the intervention was very small for disability and QoL. The quality of evidence was rated as moderate for pain and physical function and low and very low for disability and QoL, respectively, using the GRADE approach.

CONCLUSIONS

Digital-based structured SMPs may result in improvement in pain and physical function that is largely sustained at the 12-month follow-up in people with knee and hip OA. The effects on disability and QoL are smaller and less clear. The quality of evidence is moderate to low, and further research is required to confirm the findings of the review and assess the effects of digital-based structured SMPs on other health-related outcomes.

Effectiveness of Weight-Loss Interventions for Reducing Pain and Disability in People With Common Musculoskeletal Disorders: A Systematic Review With Meta-Analysis

OBJECTIVE

To assess the effectiveness of weight-loss interventions on pain and disability in people with knee and hip osteoarthritis (OA) and spinal pain.

DESIGN

Intervention systematic review.

LITERATURE SEARCH

Twelve online databases and clinical trial registries.

STUDY SELECTION CRITERIA

Randomized controlled trials of any weight-loss intervention (eg, diet, physical activity, surgical, pharmaceutical) that reported pain or disability outcomes in people with knee or hip OA or spinal pain.

DATA SYNTHESIS

We calculated mean differences or standardized mean differences (SMDs) and 95% confidence intervals (CIs). We used the Cochrane risk of bias tool to assess risk of bias and the Grading of Recommendations Assessment, Development, and Evaluation tool to judge credibility of evidence.

RESULTS

Twenty-two trials with 3602 participants were included. There was very low- to very low-credibility evidence for a moderate effect of weight-loss interventions on pain intensity (10 trials, n = 1806; SMD, -0.54; 95% CI: -0.86, -0.22; I² = 87%, P<.001) and a small effect on disability (11 trials, n = 1821; SMD, -0.32; 95% CI: -0.49, -0.14; I² = 58%, P<.001) compared to minimal care for people with OA. For knee OA, there was low- to moderate-credibility evidence that weight-loss interventions were not more effective than exercise only for pain intensity and disability, respectively (4 trials, n = 673; SMD, -0.13; 95% CI: -0.40, 0.14; I² = 55%; 5 trials, n = 737; SMD, -0.20; 95% CI: -0.41, 0.00; I² = 32%).

CONCLUSION

Weight-loss interventions may provide small to moderate improvements in pain and disability for OA compared to minimal care. There was limited and inconclusive evidence for weight-loss interventions targeting spinal pain. J Orthop Sports Phys Ther 2020;50(6):319-333. Epub 9 Apr 2020. doi:10.2519/jospt.2020.9041.

Does telephone-delivered exercise advice and support by physiotherapists improve pain and/or function in people with knee osteoarthritis? Telecare randomised controlled trial

Objective

Evaluate a physiotherapist-led telephone-delivered exercise advice and support intervention for people with knee osteoarthritis.

Methods

Participant-blinded, assessor-blinded randomised controlled trial. 175 people were randomly allocated to (1) existing telephone service (≥1 nurse consultation for self-management advice) or (2) exercise advice and support (5–10 consultations with a physiotherapist trained in behaviour change for a personalised strengthening and physical activity programme) plus the existing service. Primary outcomes were overall knee pain (Numerical Rating Scale, range 0–10) and physical function (Western Ontario and McMaster Universities Osteoarthritis Index, range 0–68) at 6 months. Secondary outcomes, cost-effectiveness and 12-month follow-up were included.

Results

165 (94%) and 158 (90%) participants were retained at 6 and 12 months, respectively. At 6 months, exercise advice and support resulted in greater improvement in function (mean difference 4.7 (95% CI 1.0 to 8.4)), but not overall pain (0.7, 0.0 to 1.4). Eight of 14 secondary outcomes favoured exercise advice and support at 6 months, including pain on daily activities, walking pain, pain self-efficacy, global improvements across multiple domains (overall improvement, improved pain, improved function and improved physical activity) and satisfaction. By 12 months, most outcomes were similar between groups. Exercise advice and support cost $A514/participant and did not save other health service resources.

Conclusion

Telephone-delivered physiotherapist-led exercise advice and support modestly improved physical function but not the co-primary outcome of knee pain at 6 months. Functional benefits were not sustained at 12 months. The clinical significance of this effect is uncertain.

Cognitive Mediators of Change in Physical Functioning in Response to a Multifaceted Intervention for Managing Osteoarthritis

PURPOSE

Although non-pharmacological interventions have been shown to improve physical functioning in individuals with osteoarthritis (OA), the mechanisms by which this occurs are often unclear. This study assessed whether changes in arthritis self-efficacy, perceived pain control, and pain catastrophizing mediated changes in physical functioning following an osteoarthritis intervention involving weight management, physical activity, and cognitive-behavioral pain management.

METHOD

Three hundred Veteran patients of 30 primary care providers with knee and/or hip OA were cluster randomized to an OA intervention group or usual care. The OA intervention included a 12-month phone-based patient behavioral protocol (weight management, physical activity, and cognitive-behavioral pain management) plus patient-specific OA treatment recommendations delivered to primary care providers.

RESULTS

Using linear mixed models adjusted for provider clustering, we observed that baseline to 6-month changes in arthritis self-efficacy and pain control partially mediated baseline to 12-month physical functioning improvements for the intervention group; catastrophizing did not.

CONCLUSION

Findings of a mediating role of arthritis self-efficacy and pain control in intervention-related functional changes are consistent with hypotheses and align with theoretical assertions of the role of cognitions in cognitive and behavioral interventions for chronic pain. However, contrary to hypotheses, catastrophizing was not found to be a mediator of these changes.

Effectiveness of telephone-based interventions for managing osteoarthritis and spinal pain: a systematic review and meta-analysis

BACKGROUND

Osteoarthritis and spinal pain are common and burdensome conditions; however, the majority of patients with these conditions do not receive care that is consistent with clinical practice guidelines. Telehealth models of care have the potential to improve care for osteoarthritis and spinal pain patients. The aim of this review was to assess the effectiveness of verbal real-time telehealth interventions, including telephone-based and videoconferencing interventions to reduce pain intensity and disability in patients with osteoarthritis of the knee or hip and spinal pain (back or neck pain).

METHODS

We searched seven electronic databases from inception to May 2018. Randomised controlled trials (RCTs), cluster-RCTs, and non-randomised controlled trials were included. Two review authors independently extracted data for each included study. Primary outcomes were pain intensity and disability. We conducted primary meta-analyses combining all conditions with similar interventions and comparators. Standardised mean difference (SMD) and 95% confidence intervals (CIs) were calculated using random effects models. We used the Cochrane Risk of Bias tool to assess risk of bias, and GRADE to evaluate the quality of evidence.

RESULTS

We included 23 studies with 56 trial arms and 4,994 participants. All studies utilised telephone-based interventions. Only two studies used a telephone only approach and the remainder included educational materials and/or face-to-face components. We found no studies utilising videoconferencing. Meta-analysis showed telephone-based interventions (with educational materials) for osteoarthritis and spinal pain improved pain intensity (n = 5 trials, n = 1,357 participants, SMD -0.27, 95% CI [-0.53, -0.01], Tau2 = 0.06, I 2 = 74%; moderate-quality evidence) and disability (n = 7 trials, n = 1,537 participants, SMD -0.21, 95% CI [-0.40, -0.02], Tau2 = 0.03, I 2 = 56%; moderate-quality evidence) compared to usual care. Meta-analyses found telephone with face-to-face interventions does not improve pain and disability compared to usual care or face-to-face care alone.

DISCUSSION

We are moderately confident that telephone-based interventions reduce pain intensity and disability in patients with osteoarthritis and spinal pain compared to usual care, but telephone plus face-to-face interventions are no more effective than usual care or face-to-face interventions alone.

Gaps in appropriate use of treatment strategies in osteoarthritis

Optimal management of osteoarthritis (OA) requires a combination of therapies, with behavioral (e.g., exercise and weight management) and rehabilitative components at the core, accompanied by pharmacological treatments and, in later stages, consideration of joint replacement surgery. Although multiple sets of OA treatment guidelines have been developed, there are gaps in the implementation of these recommendations. Key areas of concern include the underuse of exercise, weight management, and other behavioral and rehabilitation strategies as well as the overuse of opioid analgesics. In this review, we describe the major categories of treatment strategies for OA, including self-management, physical activity, weight management, physical therapy and other rehabilitative therapies, pharmacotherapies, and joint replacement surgery. For each category, we discuss the current evidence base to report on appropriate use, data regarding adherence to treatment recommendations, and potential approaches to optimize use.

Development of a Tailored Intervention With Computerized Clinical Decision Support to Improve Quality of Care for Patients With Knee Osteoarthritis: Multi-Method Study

BACKGROUND

Clinical practice patterns greatly diverge from evidence-based recommendations to manage knee osteoarthritis conservatively before resorting to surgery.

OBJECTIVE

This study aimed to tailor a guideline-based computerized decision support (CDS) intervention that facilitates the conservative management of knee osteoarthritis.

METHODS

Experts with backgrounds in clinical medicine, research, implementation, or health informatics suggested the most important recommendations for implementation, how to develop an implementation strategy, and how to form the CDS algorithms. In 6 focus group sessions, 8 general practitioners and 22 patients from Norway, Belgium, and Finland discussed the suggested CDS intervention and identified factors that would be most critical for the success of the intervention. The focus group moderators used the GUideline Implementation with DEcision Support checklist, which we developed to support consideration of CDS success factors.

RESULTS

The experts prioritized 9 out of 22 recommendations for implementation. We formed the concept for 6 CDS algorithms to support implementation of these recommendations. The focus group suggested 59 unique factors that could affect the success of the presented CDS intervention. Five factors (out of the 59) were prioritized by focus group participants in every country, including the perceived potential to address the information needs of both patients and general practitioners; the credibility of CDS information; the timing of CDS for patients; and the need for personal dialogue about CDS between the general practitioner and the patient.

CONCLUSIONS

The focus group participants supported the CDS intervention as a tool to improve the quality of care for patients with knee osteoarthritis through shared, evidence-based decision making. We aim to develop and implement the CDS based on these study results. Future research should address optimal ways to (1) provide patient-directed CDS, (2) enable more patient-specific CDS within the context of patient complexity, and (3) maintain user engagement with CDS over time.

Effects of a Home-Based Telephone-Supported Physical Activity Program for Older Adult Veterans With Chronic Low Back Pain

BACKGROUND

Chronic low back pain (CLBP) is highly prevalent in older adults, leading to functional decline.

OBJECTIVE

The objective of this study was to evaluate physical activity (PA) only and PA plus cognitive-behavioral therapy for pain (CBT-P) among older adult veterans with CLBP.

DESIGN

This study was a pilot randomized trial comparing a 12-week telephone-supported PA-only intervention group (PA group) or PA plus CBT-P intervention group (PA + CBT-P group) and a wait-list control group (WL group).

SETTING

The study setting was the Durham Veterans Affairs Health Care System.

PARTICIPANTS

The study participants were 60 older adults with CLBP.

INTERVENTIONS

The PA intervention included stretching, strengthening, and aerobic activities; CBT-P covered activity pacing, relaxation techniques, and cognitive restructuring.

MEASUREMENTS

Feasibility measures included enrollment and completion metrics; acceptability was measured by completed phone calls. Primary outcomes included the Timed "Up & Go" Test and the PROMIS Health Assessment Questionnaire. Generalized linear mixed models were used to estimate changes within and between groups. Effect sizes were calculated with the Cohen d. Adverse effects were measured by self-report.

RESULTS

The mean participant age was 70.3 years; 53% were not white, and 93% were men. Eighty-three percent of participants completed the study, and the mean number of completed phone calls was 10 (of 13). Compared with the results for the WL group, small to medium treatment effects were found for the intervention groups in the Timed "Up & Go" Test (PA group: -2.94 [95% CI = -6.24 to 0.35], effect size = -0.28; PA + CBT-P group: -3.26 [95% CI = -6.69 to 0.18], effect size = -0.31) and the PROMIS Health Assessment Questionnaire (PA group: -6.11 [95% CI = -12.85 to 0.64], effect size = -0.64; PA + CBT-P group: -4.10 [95% CI = -11.69 to 3.48], effect size = -0.43). Small treatment effects favored PA over PA + CBT-P. No adverse effects were noted.

LIMITATIONS

This was a pilot study, and a larger study is needed to verify the results.

CONCLUSIONS

This pilot trial demonstrated that home-based telephone-supported PA interventions were feasible, acceptable, and safe for older adult veterans. The results provide support for a larger trial investigating these interventions.

Prevalence of and characteristics associated with insomnia and obstructive sleep apnea among veterans with knee and hip osteoarthritis

BACKGROUND

Few studies have examined patterns of specific sleep problems among individuals with osteoarthritis (OA). The primary objective of this study was to examine prevalence of symptoms of insomnia and obstructive sleep apnea (OSA) among Veterans with OA. Secondary objectives were to assess proportions of individuals with insomnia and OSA symptoms who may have been undiagnosed and to examine Veterans' characteristics associated with insomnia and OSA symptoms.

METHODS

Veterans (n = 300) enrolled in a clinical trial completed the Insomnia Severity Index (ISI) and the Berlin Questionnaire (BQ) at baseline; proportions of participants with symptoms consistent with insomnia and OSA were calculated, using standard cut-offs for ISI and BQ. For Veterans with insomnia and OSA symptoms, electronic medical records were searched to identify whether there was a diagnosis code for these conditions. Multivariable linear (ISI) and logistic (BQ) regression models examined associations of the following characteristics with symptoms of insomnia and OSA: age, gender, race, self-reported general health, body mass index (BMI), diagnosis of post-traumatic stress disorder (PTSD), pain severity, depressive symptoms, number of joints with arthritis symptoms and opioid use.

RESULTS

Symptoms consistent with insomnia and OSA were found in 53 and 66% of this sample, respectively. Among participants screening positive for insomnia and OSA, diagnosis codes for these disorders were present in the electronic medical record for 22 and 51%, respectively. Characteristics associated with insomnia were lower age (β (SE) = - 0.09 (0.04), 95% confidence interval [CI] = - 0.16, - 0.02), having a PTSD diagnosis (β (SE) = 1.68 (0.73), CI = 0.25, 3.11), greater pain severity (β (SE) = 0.36 (0.09), CI = 0.17, 0.55), and greater depressive symptoms (β (SE) = 0.84 (0.07), CI = 0.70, 0.98). Characteristics associated with OSA were higher BMI (odds ratio [OR] = 1.13, CI = 1.06, 1.21), greater depressive symptoms (OR = 1.12, CI = 1.05, 1.20), and opioid use (OR = 0.51, CI = 0.26, 0.99).

CONCLUSIONS

Insomnia and OSA symptoms were very common in Veterans with OA, and a substantial proportion of individuals with symptoms may have been undiagnosed. Characteristics associated with insomnia and OSA symptoms were consistent with prior studies.

The effectiveness of interventions aimed at increasing physical activity in adults with persistent musculoskeletal pain: a systematic review and meta-analysis

BACKGROUND

Individuals with persistent musculoskeletal pain (PMP) have an increased risk of developing co-morbid health conditions and for early-mortality compared to those without pain. Despite irrefutable evidence supporting the role of physical activity in reducing these risks; there has been limited synthesis of the evidence, potentially impacting the optimisation of these forms of interventions. This review examines the effectiveness of interventions in improving levels of physical activity and the components of these interventions.

METHODS

Randomised and quasi-randomised controlled trials were included in this review. The following databases were searched from inception to March 2016: CENTRAL in the Cochrane Library, Cochrane Database of Systematic Reviews (CDSR), MEDLINE, Embase, CINAHL, PsycINFO and AMED. Two reviewers independently screened citations, assessed eligibility, extracted data, assessed risk of bias and coded intervention content using the behaviour change taxonomy (BCTTv1) of 93 hierarchically clustered techniques. GRADE was used to rate the quality of the evidence.

RESULTS

The full text of 276 articles were assessed for eligibility, twenty studies involving 3441 participants were included in the review. Across the studies the mean number of BCTs coded was eight (range 0-16); with 'goal setting' and 'instruction on how to perform the behaviour' most frequently coded. For measures of subjective physical activity: interventions were ineffective in the short term, based on very low quality evidence; had a small effect in the medium term based on low quality evidence (SMD 0.25, 95% CI 0.01 to 0.48) and had a small effect in the longer term (SMD 0.21 95% CI 0.08 to 0.33) based on moderate quality evidence. For measures of objective physical activity: interventions were ineffective - based on very low to low quality evidence.

CONCLUSIONS

There is some evidence supporting the effectiveness of interventions in improving subjectively measured physical activity however, the evidence is mostly based on low quality studies and the effects are small. Given the quality of the evidence, further research is likely/very likely to have an important impact on our confidence in effect estimates and is likely to change the estimates. Future studies should provide details on intervention components and incorporate objective measures of physical activity.

Patient, Provider, and Combined Interventions for Managing Osteoarthritis in Primary Care: A Cluster Randomized Trial

BACKGROUND

A single-site study showed that a combined patient and provider intervention improved outcomes for patients with knee osteoarthritis, but it did not assess separate effects of the interventions.

OBJECTIVE

To examine whether patient-based, provider-based, and patient-provider interventions improve osteoarthritis outcomes.

DESIGN

Cluster randomized trial with assignment to patient, provider, and patient-provider interventions or usual care. (ClinicalTrials.gov: NCT01435109).

SETTING

10 Duke University Health System community-based primary care clinics.

PARTICIPANTS

537 outpatients with symptomatic hip or knee osteoarthritis.

INTERVENTION

The telephone-based patient intervention focused on weight management, physical activity, and cognitive behavioral pain management. The provider intervention involved electronic delivery of patient-specific osteoarthritis treatment recommendations to providers.

MEASUREMENTS

The primary outcome was the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) total score at 12 months. Secondary outcomes were objective physical function (Short Physical Performance Battery) and depressive symptoms (Patient Health Questionnaire). Linear mixed models assessed the difference in improvement among groups.

RESULTS

No difference was observed in WOMAC score changes from baseline to 12 months in the patient (-1.5 [95% CI, -5.1 to 2.0]; P = 0.40), provider (2.5 [CI, -0.9 to 5.9]; P = 0.152), or patient-provider (-0.7 [CI, -4.2 to 2.8]; P = 0.69) intervention groups compared with usual care. All groups had improvements in WOMAC scores at 12 months (range, -3.7 to -7.7). In addition, no differences were seen in objective physical function or depressive symptoms at 12 months in any of the intervention groups compared with usual care.

LIMITATIONS

The study involved 1 health care network. Data on provider referrals were not collected.

CONCLUSION

Contrary to a previous study of a combined patient and provider intervention for osteoarthritis in a Department of Veterans Affairs medical center, this study found no statistically significant improvements in the osteoarthritis intervention groups compared with usual care.

Osteoarthritis year in review 2016: clinical

Both epidemiologic and clinical research continues to be performed in osteoarthritis (OA). While epidemiologic studies identify risk factors for incident and progressive disease, clinical studies explore the role of both non-pharmacologic and pharmacologic treatments, including oral and intra-articular therapies. We performed a systematic review of the literature using PubMed for the time period between April 1, 2015 to February 22, 2016. Selected publications in the areas of both epidemiology and treatment are reviewed in this article.

Taking ACTION to reduce pain: ACTION study rationale, design and protocol of a randomized trial of a proactive telephone-based coaching intervention for chronic musculoskeletal pain among African Americans

Background

Rates of chronic pain are rising sharply in the United States and worldwide. Presently, there is evidence of racial disparities in pain treatment and treatment outcomes in the United States but few interventions designed to address these disparities. There is growing consensus that chronic musculoskeletal pain is best addressed by a biopsychosocial approach that acknowledges the role of psychological and environmental factors, some of which differ by race.

Methods/Design

The primary aim of this randomized controlled trial is to test the effectiveness of a non-pharmacological, self-regulatory intervention, administered proactively by telephone, at improving pain outcomes and increasing walking among African American patients with hip, back and knee pain. Participants assigned to the intervention will receive a telephone counselor delivered pedometer-mediated walking intervention that incorporates action planning and motivational interviewing. The intervention will consist of 6 telephone counseling sessions over an 8–10 week period. Participants randomly assigned to Usual Care will receive an informational brochure and a pedometer. The primary outcome is chronic pain-related physical functioning, assessed at 6 months, by the revised Roland and Morris Disability Questionnaire, a measure recommended by the Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials (IMMPACT). We will also examine whether the intervention improves other IMMPACT-recommended domains (pain intensity, emotional functioning, and ratings of overall improvement). Secondary objectives include examining whether the intervention reduces health care service utilization and use of opioid analgesics and whether key contributors to racial/ethnic disparities targeted by the intervention mediate improvement in chronic pain outcomes Measures will be assessed by mail and phone surveys at baseline, three months, and six months. Data analysis of primary aims will follow intent-to-treat methodology.

Discussion

We will tailor our intervention to address key contributors to racial pain disparities and examine the effects of the intervention on important pain treatment outcomes for African Americans with chronic musculoskeletal pain.

Pain coping skills training for African Americans with osteoarthritis (STAART): study protocol of a randomized controlled trial

BACKGROUND

African Americans bear a disproportionate burden of osteoarthritis (OA), with higher prevalence rates, more severe pain, and more functional limitations. One key barrier to addressing these disparities has been limited engagement of African Americans in the development and evaluation of behavioral interventions for management of OA. Pain Coping Skills Training (CST) is a cognitive-behavioral intervention with shown efficacy to improve OA-related pain and other outcomes. Emerging data indicate pain CST may be a promising intervention for reducing racial disparities in OA symptom severity. However, there are important gaps in this research, including incorporation of stakeholder perspectives (e.g. cultural appropriateness, strategies for implementation into clinical practice) and testing pain CST specifically among African Americans with OA. This study will evaluate the effectiveness of a culturally enhanced pain CST program among African Americans with OA.

METHODS/DESIGN

This is a randomized controlled trial among 248 participants with symptomatic hip or knee OA, with equal allocation to a pain CST group and a wait list (WL) control group. The pain CST program incorporated feedback from patients and other stakeholders and involves 11 weekly telephone-based sessions. Outcomes are assessed at baseline, 12 weeks (primary time point), and 36 weeks (to assess maintenance of treatment effects). The primary outcome is the Western Ontario and McMaster Universities Osteoarthritis Index, and secondary outcomes include self-efficacy, pain coping, pain interference, quality of life, depressive symptoms, and global assessment of change. Linear mixed models will be used to compare the pain CST group to the WL control group and explore whether participant characteristics are associated with differential improvement in the pain CST program. This research is in compliance with the Helsinki Declaration and was approved by the Institutional Review Boards of the University of North Carolina at Chapel Hill, Durham Veterans Affairs Medical Center, East Carolina University, and Duke University Health System.

DISCUSSION

This culturally enhanced pain CST program could have a substantial impact on outcomes for African Americans with OA and may be a key strategy in the reduction of racial health disparities.

The effects of on-screen, point of care computer reminders on processes and outcomes of care

BACKGROUND

The opportunity to improve care by delivering decision support to clinicians at the point of care represents one of the main incentives for implementing sophisticated clinical information systems. Previous reviews of computer reminder and decision support systems have reported mixed effects, possibly because they did not distinguish point of care computer reminders from e-mail alerts, computer-generated paper reminders, and other modes of delivering 'computer reminders'.

OBJECTIVES

To evaluate the effects on processes and outcomes of care attributable to on-screen computer reminders delivered to clinicians at the point of care.

SEARCH STRATEGY

We searched the Cochrane EPOC Group Trials register, MEDLINE, EMBASE and CINAHL and CENTRAL to July 2008, and scanned bibliographies from key articles.

SELECTION CRITERIA

Studies of a reminder delivered via a computer system routinely used by clinicians, with a randomised or quasi-randomised design and reporting at least one outcome involving a clinical endpoint or adherence to a recommended process of care.

DATA COLLECTION AND ANALYSIS

Two authors independently screened studies for eligibility and abstracted data. For each study, we calculated the median improvement in adherence to target processes of care and also identified the outcome with the largest such improvement. We then calculated the median absolute improvement in process adherence across all studies using both the median outcome from each study and the best outcome.

MAIN RESULTS

Twenty-eight studies (reporting a total of thirty-two comparisons) were included. Computer reminders achieved a median improvement in process adherence of 4.2% (interquartile range (IQR): 0.8% to 18.8%) across all reported process outcomes, 3.3% (IQR: 0.5% to 10.6%) for medication ordering, 3.8% (IQR: 0.5% to 6.6%) for vaccinations, and 3.8% (IQR: 0.4% to 16.3%) for test ordering. In a sensitivity analysis using the best outcome from each study, the median improvement was 5.6% (IQR: 2.0% to 19.2%) across all process measures and 6.2% (IQR: 3.0% to 28.0%) across measures of medication ordering. In the eight comparisons that reported dichotomous clinical endpoints, intervention patients experienced a median absolute improvement of 2.5% (IQR: 1.3% to 4.2%). Blood pressure was the most commonly reported clinical endpoint, with intervention patients experiencing a median reduction in their systolic blood pressure of 1.0 mmHg (IQR: 2.3 mmHg reduction to 2.0 mmHg increase).

AUTHORS' CONCLUSIONS

Point of care computer reminders generally achieve small to modest improvements in provider behaviour. A minority of interventions showed larger effects, but no specific reminder or contextual features were significantly associated with effect magnitude. Further research must identify design features and contextual factors consistently associated with larger improvements in provider behaviour if computer reminders are to succeed on more than a trial and error basis.
