Cost-effectiveness of adjunct non-pharmacological interventions for osteoarthritis of the knee

A modern way to teach and practice manual therapy

BACKGROUND

Musculoskeletal conditions are the leading contributor to global disability and health burden. Manual therapy (MT) interventions are commonly recommended in clinical guidelines and used in the management of musculoskeletal conditions. Traditional systems of manual therapy (TMT), including physiotherapy, osteopathy, chiropractic, and soft tissue therapy have been built on principles such as clinician-centred assessment, patho-anatomical reasoning, and technique specificity. These historical principles are not supported by current evidence. However, data from clinical trials support the clinical and cost effectiveness of manual therapy as an intervention for musculoskeletal conditions, when used as part of a package of care.

PURPOSE

The purpose of this paper is to propose a modern evidence-guided framework for the teaching and practice of MT which avoids reference to and reliance on the outdated principles of TMT. This framework is based on three fundamental humanistic dimensions common in all aspects of healthcare: safety, comfort, and efficiency. These practical elements are contextualised by positive communication, a collaborative context, and person-centred care. The framework facilitates best-practice, reasoning, and communication and is exemplified here with two case studies.

METHODS

A literature review stimulated by a new method of teaching manual therapy, reflecting contemporary evidence, being trialled at a United Kingdom education institute. A group of experienced, internationally-based academics, clinicians, and researchers from across the spectrum of manual therapy was convened. Perspectives were elicited through reviews of contemporary literature and discussions in an iterative process. Public presentations were made to multidisciplinary groups and feedback was incorporated. Consensus was achieved through repeated discussion of relevant elements.

CONCLUSIONS

Manual therapy interventions should include both passive and active, person-empowering interventions such as exercise, education, and lifestyle adaptations. These should be delivered in a contextualised healing environment with a well-developed person-practitioner therapeutic alliance. Teaching manual therapy should follow this model.

Cost-Effectiveness of Treatments for Musculoskeletal Conditions Offered by Physiotherapists: A Systematic Review of Trial-Based Evaluations

BACKGROUND

Musculoskeletal conditions are a leading contributor to disability worldwide. The treatment of these conditions accounts for 7% of health care costs in Germany and is often provided by physiotherapists. Yet, an overview of the cost-effectiveness of treatments for musculoskeletal conditions offered by physiotherapists is missing. This review aims to provide an overview of full economic evaluations of interventions for musculoskeletal conditions offered by physiotherapists.

METHODS

We systematically searched for publications in Medline, EconLit, and NHS-EED. Title and abstracts, followed by full texts were screened independently by two authors. We included trial-based full economic evaluations of physiotherapeutic interventions for patients with musculoskeletal conditions and allowed any control group. We extracted participants' information, the setting, the intervention, and details on the economic analyses. We evaluated the quality of the included articles with the Consensus on Health Economic Criteria checklist.

RESULTS

We identified 5141 eligible publications and included 83 articles. The articles were based on 78 clinical trials. They addressed conditions of the spine (n = 39), the upper limb (n = 8), the lower limb (n = 30), and some other conditions (n = 6). The most investigated conditions were low back pain (n = 25) and knee and hip osteoarthritis (n = 16). The articles involved 69 comparisons between physiotherapeutic interventions (in which we defined primary interventions) and 81 comparisons in which only one intervention was offered by a physiotherapist. Physiotherapeutic interventions compared to those provided by other health professionals were cheaper and more effective in 43% (18/42) of the comparisons. Ten percent (4/42) of the interventions were dominated. The overall quality of the articles was high. However, the description of delivered interventions varied widely and often lacked details. This limited fair treatment comparisons.

CONCLUSIONS

High-quality evidence was found for physiotherapeutic interventions to be cost-effective, but the result depends on the patient group, intervention, and control arm. Treatments of knee and back conditions were primarily investigated, highlighting a need for physiotherapeutic cost-effectiveness analyses of less often investigated joints and conditions. The documentation of provided interventions needs improvement to enable clinicians and stakeholders to fairly compare interventions and ultimately adopt cost-effective treatments.

Devices for osteoarthritis symptoms treatment: a patent review

INTRODUCTION

Osteoarthritis is a musculoskeletal disease that can lead to the loss and inability of those affected to perform normal daily functions, which leads to a decrease in quality of life. The main symptoms of osteoarthritis are tenderness, joint pain, stiffness, crepitus, limited movement, and local inflammation.

AREAS COVERED

The selected patents were deposited from 2010 to April 2022 involving 57 documents that were in line with the study objective in the final selection. The patents were classified in years, country, and applicants. Also, the therapeutic fields that presented the most documents were electrical stimulation, phototherapy, and ultrasound, followed by magnetic, electromagnetic, and thermotherapy. Therefore, the most current therapies used in the documents are already on the market.

EXPERT OPINION

Although the OA is cureless, non-surgical treatments are classified as the primary management approach for this disease. The pharmacological and non-pharmacological therapies are employed to reduce its prevalence and ensure the effectiveness of treatments. A strategy for relieving OA symptoms is non-pharmacological treatment, which can be based on exercise and patient education, combined with other alternative therapies. These therapies are used as supplements to the main OA treatments, enhancing the effectiveness of treatment outcomes.

Economic evaluation of acupuncture as an adjunctive treatment with usual care for mild-to-moderate knee osteoarthritis: A Markov model-based analysis

Background

Collaborative care (CC), in which acupuncture is combined with usual care (UC), improves clinical outcomes and increases costs in knee osteoarthritis (KOA). We evaluated the economic feasibility of CC for Korean female patients with mild-to-moderate KOA by using a cost-effectiveness approach.

Methods

Two alternatives for KOA (1. UC as a comparator; and 2. CC as an intervention) were defined based on clinical guidelines, official Korean statistics, and expert validation. Each alternative was simulated in a Markov model every 6 months for 10 years. Estimates of costs, utilities, and transition probabilities were obtained from official statistics and previous studies. The effectiveness of CC was synthesized from randomized controlled trials. A base-case analysis of a limited societal perspective, univariate sensitivity analysis, and probability sensitivity analysis were performed. An annual discount rate of 4.5% and threshold of 20,000 United States dollar per Quality-adjusted life year (USD/QALY) were applied.

Results

Every incremental cost-effectiveness ratio (ICER) of CC calculated from the analyses was sub-threshold. In the base-case analysis, with a limited societal perspective, the ICER was 11,085 USD/QALY. The ICERs from the univariate sensitivity analyses were -2,577-16,748 USD/QALY. The average ICER in the probability sensitivity analysis was 12,412 USD/QALY. When the threshold surpassed 8,000 USD/QALY, the cost-effectiveness of CC exceeded 50%. The probability was 70.27% when the threshold was 20,000 USD/QALY.

Conclusions

CC for Korean female patients with mild-to-moderate KOA was generally cost-effective. Considering the limitations of the evidence, we propose a re-evaluation using further clinical studies in the future.

Cost-utility analysis and net monetary benefit of Platelet Rich Plasma (PRP), intra-articular injections in compared to Plasma Rich in Growth Factors (PRGF), Hyaluronic Acid (HA) and ozone in knee osteoarthritis in Iran

PURPOSE

To evaluate the cost-effectiveness of Platelet Rich Plasma (PRP), Plasma Rich in Growth Factors (PRGF), Hyaluronic Acid (HA) and ozone as effective treatment approaches in knee osteoarthritis management from Iran Health care perspective.

METHODS

A decision tree model was conducted to assess the cost-effectiveness of four common intra-articular treatment approaches in patients with mild and moderate knee osteoarthritis. The data on clinical effectiveness was obtained from a randomized controlled trial (RCT) conducted in Iran and used to estimate utility values. The direct medical costs were estimated according to tariffs for public medical centers and hospitals, approved by the Iran Ministry of Health and Medical Education in 2021. The incremental cost-effectiveness ratio (ICER) and the net monetary benefit (NMB) were used to evaluate the cost-utility analysis. Deterministic and probabilistic sensitivity analyses are performed to investigate the robustness of the results and account for the different sources of uncertainty.

RESULTS

In this study, HA intra-articular injection-related costs ($581.67/patient) were defined as the highest cost, followed by PRGF ($328.10/patient), PRP (318.58/patient), and Ozone (103.20/patient). According to the utility value, PRP and PRGF (0.68) have the same and the most utility among Intra-articular injections in knee osteoarthritis management. However, the PRP injection method was identified as the most cost-effective intervention due to its high NMB and ICER estimates. Based on the Monte Carlo Simulation, PR intervention, compared to other ones, was introduced as the dominant strategy regarding knee OA management, with a WTP of $10,000 for 100% of cases.

CONCLUSION

The study result demonstrated that intra-articular injection of PRP, compare to other injections, is a cost-effective treatment option for patients with mild and moderate knee osteoarthritis. In addition, intra-articular injection of PRP was identified as the best injection, with the highest level of net monetary benefit, for knee OA management.

Group Acupuncture Therapy With Yoga Therapy for Chronic Neck, Low Back, and Osteoarthritis Pain in Safety Net Settings for an Underserved Population: A Feasibility Pilot Study

Background

Acupuncture and yoga have both been shown to be effective in chronic pain. Underrepresented populations have poorer pain outcomes with less access to effective pain care.

Objective

To assess the feasibility of bundling group acupuncture with yoga therapy for chronic neck, back or osteoarthritis pain in safety net settings.

Methods

This was a feasibility pilot in Bronx and Harlem primary care community health centers. Participants with chronic neck, back or osteoarthritis pain received acupuncture and yoga therapy over a 10-week period. Participants received 10 weekly acupuncture treatments in group setting; with Yoga therapy sessions beginning immediately following the 3rd session. Primary outcome was pain interference and pain intensity on the Brief Pain Inventory (BPI); Outcomes were measured at baseline, 10-week close of intervention, and 24-week follow-up.

Results

93 patients were determined to be eligible and completed the baseline interview. The majority of participants were non-White and Medicaid recipients. 78 (84%) completed the intervention and 10-week survey, and 58 (62%) completed the 24-week post intervention survey. Participants received an average number of 6.5 acupuncture sessions (out of a possible 10), and 4 yoga sessions (out of a possible 8) over the 10-week intervention. Patients showed statistically significant improvements in pain at the close of the intervention and at a somewhat lesser rate, at 24-weeks post intervention. Challenges included telephone outreach and site coordination integrating acupuncture with yoga therapy. The trial also had to be stopped early due to the COVID-19 pandemic.

Conclusions

Bundling acupuncture therapy and yoga therapy is feasible for an underrepresented population with chronic pain in urban community health centers with preliminary indications of acceptability and benefit to participants.

A bibliometric analysis of traditional Chinese non-pharmacological therapies in the treatment of knee osteoarthritis from 2012 to 2022

Objective

The benefits of traditional Chinese non-pharmacological therapies in the treatment of Knee osteoarthritis (KOA) are receiving increasing attention. Therefore, this study aims to systematically analyze the global research on the treatment of KOA by Chinese traditional non-pharmacological therapies using bibliometric analysis and present the results with a knowledge map form.

Methods

Literature related to traditional Chinese non-pharmacological therapies used in the treatment of KOA from 2012 to 2022 was searched from the Web of Science core database and PubMed database. CiteSpace, SCImago Graphica and VOSviewer were used to extract nations, institutions, journals, authors, references, keywords, as well as the most widely used acupoints, therapies and evaluation indexes.

Results

A total of 375 literature have been included. 32 countries around the world have participated in the research. China, the United States, and Europe were at the center of the global cooperation network. The most prolific institutions and authors were from China represented by Cun-zhi Liu and Jian-feng Tu of Beijing University of Chinese Medicine, the institution with the highest cited frequency was University of York, and "Osteoarthritis Cartilage" was the most frequently cited journal. The most frequently cited literature was "OARSI guidelines for the non-surgical management of knee, hip, and poly articular osteoarthritis." 22 kinds of Chinese non-pharmacological therapies were used to treat KOA, among which acupuncture was the most commonly used one, and ST36 (Zusanli) and WOMAC were the most commonly selected acupoint and evaluation index.

Conclusion

In the past decade, the value of Chinese non-pharmacological therapies in the treatment of KOA has received widespread attention. It was a common concern of global researchers to relieve the pain of KOA patients and restore the quality of life. Under the background that acupuncture accounts for a relatively high proportion, the next step may consider how to make the balanced development of a variety of Chinese non-pharmacological therapies. In addition, the problem of how to eliminate the placebo effect maybe the direction of future research.

Is high intensity laser therapy more effective than other physical therapy modalities for treating knee osteoarthritis? A systematic review and network meta-analysis

Background

The use of physical therapy modalities, especially high intensity laser therapy (HILT), for individuals with knee osteoarthritis (KOA) is still controversial.

Objective

To compare the effects of HILT to other physical therapy modalities on symptoms and function in individuals with KOA.

Methods

Six databases (PubMed, Embase, Cochrane Library, Web of Science, EBSCO, and PEDro) were searched in March 2022. Included studies were randomized controlled trials involving HILT conducted on individuals with KOA. The end-trial weighted mean difference (WMD) and standard deviations (SD) with 95% confidence intervals (CI) were analyzed.

Results

Ten studies with 580 participants were obtained, of which nine were included in the final network meta-analysis. In terms of relieving pain, HILT demonstrated the highest probability of being among the most effective treatments, with surface under the cumulative ranking (SUCRA) = 100%, and compared to a control (placebo laser or exercise or a combination of both) on the visual analog scale (VAS) for pain it demonstrated significant benefits (WMD 1.66, 95% CI 1.48–1.84). For improving self-reported function, as measured by the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) total scores, the HILT SUCRA value led with 98.9%. When individuals with KOA were treated by HILT, the improvement in stiffness was statistically significant (WMD 0.78, 95% CI 0.52–1.04) but the amount of improvement was smaller than the minimal clinically important difference (MCID).

Conclusion

The current evidence suggests that HILT may be more effective than other physical therapy modalities for improving pain and function in individuals with KOA. For improving stiffness, however, it may not be clinically effective.

Characterising the Features of 381 Clinical Studies Evaluating Transcutaneous Electrical Nerve Stimulation (TENS) for Pain Relief: A Secondary Analysis of the Meta-TENS Study to Improve Future Research

Background and Objectives: Characterising the features of methodologies, clinical attributes and intervention protocols, of studies is valuable to advise directions for research and practice. This article reports the findings of a secondary analysis of the features from studies screened as part of a large systematic review of TENS (the meta-TENS study). Materials and Methods: A descriptive analysis was performed on information associated with methodology, sample populations and intervention protocols from 381 randomised controlled trials (24,532 participants) evaluating TENS delivered at a strong comfortable intensity at the painful site in adults with pain, irrespective of diagnosis. Results: Studies were conducted in 43 countries commonly using parallel group design (n = 334) and one comparator group (n = 231). Mean ± standard deviation (SD) study sample size (64.05 ± 58.29 participants) and TENS group size (27.67 ± 21.90 participants) were small, with only 13 of 381 studies having 100 participants or more in the TENS group. Most TENS interventions were ‘high frequency’ (>10 pps, n = 276) and using 100 Hz (109/353 reports that stated a pulse frequency value). Of 476 comparator groups, 54.2% were active treatments (i.e., analgesic medication(s), exercise, manual therapies and electrophysical agents). Of 202 placebo comparator groups, 155 used a TENS device that did not deliver currents. At least 216 of 383 study groups were able to access other treatments whilst receiving TENS. Only 136 out of 381 reports included a statement about adverse events. Conclusions: Clinical studies on TENS are dominated by small parallel group evaluations of high frequency TENS that are often contaminated by concurrent treatment(s). Study reports tended focus on physiological and clinical implications rather than the veracity of methodology and findings. Previously published criteria for designing and reporting TENS studies were neglected and this should be corrected in future research using insights gleaned from this analysis.

Cost Effectiveness of Pharmacological Management for Osteoarthritis: A Systematic Review

BACKGROUND AND OBJECTIVE

Osteoarthritis (OA) is a highly prevalent, disabling disease requiring chronic management that is associated with an enormous individual and societal burden. This systematic review provides a global cost-effectiveness evaluation of pharmacological therapy for the management of OA.

METHODS

Following Center for Reviews and Dissemination (CRD) guidance, a literature search strategy was undertaken using PubMed, EMBASE, Cochrane Library, Health Technology Assessment (HTA) database, and National Health Service Economic Evaluation database (NHS EED) to identify original articles containing cost-effectiveness evaluation of OA pharmacological treatment published before 4 November 2021. Risk of bias was assessed by two independent reviewers using the Joanna Briggs Institute (JBI) critical appraisal checklist for economic evaluations. The Quality of Health Economic Studies (QHES) instrument was used to assess the reporting quality of included articles.

RESULTS

Database searches identified 43 cost-effectiveness analysis studies (CEAs) on pharmacological management of OA that were conducted in 18 countries and four continents, with one study containing multiple continents. A total of four classes of drugs were assessed, including non-steroidal anti-inflammatory drugs (NSAIDs), opioid analgesics, symptomatic slow-acting drugs for osteoarthritis (SYSADOAs), and intra-articular (IA) injections. The methodological approaches of these studies showed substantial heterogeneity. The incremental cost-effectiveness ratios (ICERs) per quality-adjusted life-year (QALY) were (in 2021 US dollars) US$44.40 to US$307,013.56 for NSAIDS, US$11,984.84 to US$128,028.74 for opioids, US$10,930.17 to US$27,799.73 for SYSADOAs, and US$258.36 to US$58,447.97 for IA injections in different continents. The key drivers of cost effectiveness included medical resources, productivity, relative risks, and selected comparators.

CONCLUSION

This review showed substantial heterogeneity among studies, ranging from a finding of dominance to very high ICERs, but most studies found interventions to be cost effective based on specific ICER thresholds. Important challenges in the analysis were related to the standardization and methodological quality of studies, as well as the presentation of results.

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.

Efficacy and safety of transcutaneous electrical nerve stimulation (TENS) for acute and chronic pain in adults: a systematic review and meta-analysis of 381 studies (the meta-TENS study)

OBJECTIVE

To investigate the efficacy and safety of transcutaneous electrical nerve stimulation (TENS) for relief of pain in adults.

DESIGN

Systematic review and meta-analysis.

DATA SOURCES

Medline, Cochrane Central, Embase (and others) from inception to July 2019 and updated on 17 May 2020.

ELIGIBILITY CRITERIA FOR STUDY SELECTION

Randomised controlled trials (RCTs) comparing strong non-painful TENS at or close to the site of pain versus placebo or other treatments in adults with pain, irrespective of diagnosis.

DATA EXTRACTION AND SYNTHESIS

Reviewers independently screened, extracted data and assessed risk of bias (RoB, Cochrane tool) and certainty of evidence (Grading and Recommendations, Assessment, Development and Evaluation). Mean pain intensity and proportions of participants achieving reductions of pain intensity (≥30% or >50%) during or immediately after TENS. Random effect models were used to calculate standardised mean differences (SMD) and risk ratios. Subgroup analyses were related to trial methodology and characteristics of pain.

RESULTS

The review included 381 RCTs (24 532 participants). Pain intensity was lower during or immediately after TENS compared with placebo (91 RCTs, 92 samples, n=4841, SMD=-0·96 (95% CI -1·14 to -0·78), moderate-certainty evidence). Methodological (eg, RoB, sample size) and pain characteristics (eg, acute vs chronic, diagnosis) did not modify the effect. Pain intensity was lower during or immediately after TENS compared with pharmacological and non-pharmacological treatments used as part of standard of care (61 RCTs, 61 samples, n=3155, SMD = -0·72 (95% CI -0·95 to -0·50], low-certainty evidence). Levels of evidence were downgraded because of small-sized trials contributing to imprecision in magnitude estimates. Data were limited for other outcomes including adverse events which were poorly reported, generally mild and not different to comparators.

CONCLUSION

There was moderate-certainty evidence that pain intensity is lower during or immediately after TENS compared with placebo and without serious adverse events.

A systematic review of health economic evaluation in orthotics and prosthetics: Part 2-orthotics

BACKGROUND

Health economic evaluations (HEEs) in orthotics are in their infancy. Identification of evidence gaps and method design issues will inform the design of future HEEs that advance knowledge and contributes to policy and investment decisions.

OBJECTIVES

The aim of this systematic review was to critically appraise the existing orthotic/prosthetic health economic evaluation literature and therefore determine evidence gaps, critical method design issues, and the extent to which the literature informs orthotic policy and investment decisions.

STUDY DESIGN

Systematic review.

METHODS

A range of databases were searched using intervention- and HEE-related terms. The Consolidated Health Economic Checklist-Extended and the Checklist for Health Economic Evaluation Reporting Standards were used to identify issues with method design and reporting.

RESULTS

Nine orthotic HEEs were narrowly focused on the cost-effectiveness of low-cost orthotic devices (eg, ankle orthoses for ankle sprains). Method design (eg, cost identification and valuation) and reporting issues (eg, lack of detail about the study population) limited the extent to which this literature can inform policy and investment decisions.

CONCLUSIONS

HEEs comparing a wider variety of interventions are required, particularly for commonly used orthoses (eg, ankle-foot orthoses) and clinical presentations (eg, post-stroke). There are opportunities to strengthen future orthotic HEEs by adopting method design features (eg, microcosting and sensitivity analyses) as recommended by HEE appraisal and reporting tools.

Resolving Long-Standing Uncertainty about the Clinical Efficacy of Transcutaneous Electrical Nerve Stimulation (TENS) to Relieve Pain: A Comprehensive Review of Factors Influencing Outcome

Pain is managed using a biopsychosocial approach and pharmacological and non-pharmacological treatments. Transcutaneous electrical nerve stimulation (TENS) is a technique whereby pulsed electrical currents are administered through the intact surface of the skin with the intention of alleviating pain, akin to 'electrically rubbing pain away'. Despite over 50 years of published research, uncertainty about the clinical efficacy of TENS remains. The purpose of this comprehensive review is to critically appraise clinical research on TENS to inform future strategies to resolve the 'efficacy-impasse'. The principles and practices of TENS are described to provide context for readers unfamiliar with TENS treatment. The findings of systematic reviews evaluating TENS are described from a historical perspective to provide context for a critical evaluation of factors influencing the outcomes of randomized controlled trials (RCTs); including sample populations, outcome measures, TENS techniques, and comparator interventions. Three possibilities are offered to resolve the impasse. Firstly, to conduct large multi-centered RCTs using an enriched enrolment with randomized withdrawal design, that incorporates a 'run-in phase' to screen for potential TENS responders and to optimise TENS treatment according to individual need. Secondly, to meta-analyze published RCT data, irrespective of type of pain, to determine whether TENS reduces the intensity of pain during stimulation, and to include a detailed assessment of levels of certainty and precision. Thirdly, to concede that it may be impossible to determine efficacy due to insurmountable methodological, logistical and financial challenges. The consequences to clinicians, policy makers and funders of this third scenario are discussed. I argue that patients will continue to use TENS irrespective of the views of clinicians, policy makers, funders or guideline panel recommendations, because TENS is readily available without prescription; TENS generates a pleasant sensory experience that is similar to easing pain using warming and cooling techniques; and technological developments such as smart wearable TENS devices will improve usability in the future. Thus, research is needed on how best to integrate TENS into existing pain management strategies by analyzing data of TENS usage by expert-patients in real-world settings.

Barriers and Facilitators to Implementing Bundled Acupuncture and Yoga Therapy to Treat Chronic Pain in Community Healthcare Settings: A Feasibility Pilot

Objective: To identify factors associated with implementing bundled group acupuncture and yoga therapy (YT) to treat underserved patients with chronic pain in community health center (CHC) settings. This is not an implementation science study, but rather an organized approach for identification of barriers and facilitators to implementing these therapies as a precursor to a future implementation science study. Design: This study was part of a single-arm feasibility trial, which aimed to test the feasibility of bundling GA and YT for chronic pain in CHCs. Treatment outcomes were measured before and after the 10-week intervention period. Implementation feasibility was assessed through weekly research team meetings, weekly yoga provider meetings, monthly acupuncture provider meetings, and weekly provider surveys. Settings: The study was conducted in New York City at two Montefiore Medical Group (MMG) sites in the Bronx, and one Institute for Family Health (IFH) site in Harlem. Subjects: Participants in the feasibility trial were recruited from IFH and MMG sites, and needed to have had lower back, neck, or osteoarthritis pain for >3 months. Implementation stakeholders included the research team, providers of acupuncture and YT, referring providers, and CHC staff. Results: Implementation of these therapies was assessed using the Consolidated Framework for Implementation Research. We identified issues associated with scheduling, treatment fidelity, communication, the three-way disciplinary interaction of acupuncture, yoga, and biomedicine, space adaptation, site-specific logistical and operational requirements, and patient-provider language barriers. Issues varied as to their frequency and resolution difficulty. Conclusions: This feasibility trial identified implementation issues and resolution strategies that could be further explored in future implementation studies. Clinical Trial Registration No.: NCT04296344.

Can Medical Cannabis Therapies be Cost-Effective in the Non-Surgical Management of Chronic Knee Pain?

Introduction:

Chronic knee pain is a common musculoskeletal condition, which usually leads to decreased quality of life and a substantial financial burden. Various non-surgical treatments have been developed to relieve pain, restore function and delay surgical intervention. Research on the benefits of medical cannabis (MC) is emerging supporting its use for chronic pain conditions. The purpose of this study was to evaluate the cost-effectiveness of MC compared to current non-surgical therapies for chronic knee pain conditions.

Methods:

We conducted a cost-utility analysis from a Canadian, single payer perspective and compared various MC therapies (oils, soft gels and dried flowers at different daily doses) to bracing, glucosamine, pharmaceutical-grade chondroitin oral non-steroidal anti-inflammatory drugs (NSAIDs), and opioids. We estimated the quality-adjusted life years (QALYs) gained with each treatment over 1 year and calculated incremental cost-utility ratios (ICURs) using both the mean and median estimates for costs and utilities gained across the range of reported values. The final ICURs were compared to willingness-to-pay (WTP) thresholds of $66 714, $133 428 and $200 141 Canadian dollars (CAD) per QALY gained.

Results:

Regardless of the estimates used (mean or median), both MC oils and soft gels at both the minimal and maximal recommended daily doses were cost-effective compared to all current knee pain therapies at the lowest WTP threshold. Dried flowers were only cost-effective up to a certain dosage (0.75 and 1 g/day based on mean and median estimates, respectively), but all dosages were cost-effective when the WTP was increased to $133 428/QALY gained.

Conclusion:

Our study showed that MC may be a cost-effective strategy in the management of chronic knee pain; however, the evidence on the medical use of cannabis is limited and predominantly low-quality. Additional trials on MC are definitely needed, specifically in patients with chronic knee pain.

Community-based non-pharmacological interventions for improving pain, disability and quality of life in pregnant women with musculoskeletal conditions: protocol for a systematic review with meta-analyses

INTRODUCTION

Twenty five per cent of pregnant women with musculoskeletal pain have disabling symptoms that negatively influence quality of life. Studies have reported varying effects of non-pharmacological interventions including exercise, manipulation and pelvic belts for pregnant women with musculoskeletal problems. The overall effectiveness and acceptability of these interventions is uncertain due to lack of synthesised evidence. This protocol is for the first systematic review of community-based non-pharmacological interventions for improving pain, disability and quality of life in pregnant women with musculoskeletal conditions from studies published until August 2020.

METHODS AND ANALYSIS

A detailed search of PubMed, CINAHL, CENTRAL, Global Index Medicus, African Index Medicus, African Journal Online, Western Pacific Region Index Medicus, Latin American and Caribbean Centre on Health Science Information, Index Medicus for South-East Asia Region, IRIS (WHO digital publications), British Library for Development Studies and Google Scholar. Additional studies will be located from the reference list of identified studies and relevant systematic reviews. The databases will be searched from inception to August 2020. Appraisal of study quality will be performed with the Mixed Methods Appraisal Tool. Data will be synthesised using a mixed-studies synthesis design-the convergent synthesis. The description of interventions in all study designs will be summarised narratively. Meta-analyses will be used to statistically summarise the effectiveness of interventions in randomised controlled trials and the factors that influence these. Other quantitative studies will be summarised narratively to answer the objectives. Thematic synthesis will be used to summarise results of qualitative studies. The outcomes of interest include pain, disability and quality of life. This paper is reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols 2015 guidelines.

A systematic review of health economic evaluations in orthotics and prosthetics: Part 1 - prosthetics

BACKGROUND

The extent to which current prosthetic health economic evaluations inform healthcare policy and investment decisions is unclear. To further the knowledge in this area, existing evidence gaps and method design issues must be identified, thereby informing the design of future research.

OBJECTIVES

The aim of this systematic review was to identify evidence gaps, critical method design and reporting issues and determine the extent to which the literature informs a wide range of policy and investment decisions.

STUDY DESIGN

Systematic review.

METHODS

A range of databases were searched using intervention- and health economic evaluation-related terms. Issues with methodological design and reporting were evaluated using the Consolidated Health Economic Checklist - Extended and the Checklist for Health Economic Evaluation Reporting Standards.

RESULTS

The existing health economic evaluation literature was narrowly focused on informing within-participant component decisions. There were common method design (e.g. time horizon too short) and reporting issues (e.g. competing intervention descriptions) that limit the extent to which this literature can inform policy and investment decisions.

CONCLUSION

There are opportunities to conduct a wider variety of health economic evaluations to support within- and across-sector policy and investment decisions. Changes to aspects of the method design and reporting are encouraged for future research in order to improve the rigour of the health economic evaluation evidence.

Group Acupuncture Therapy With Yoga Therapy for Chronic Neck, Low Back, and Osteoarthritis Pain in Safety Net Setting for an Underserved Population: Design and Rationale for a Feasibility Pilot

Chronic pain is prevalent in the United States, with impact on physical and psychological functioning as well as lost work productivity. Minority and lower socioeconomic populations have increased prevalence of chronic pain with less access to pain care, poorer outcomes, and higher risk of fatal opioid overdose. Acupuncture therapy is effective in treating chronic pain conditions including chronic low back pain, neck pain, shoulder pain, and knee pain from osteoarthritis. Acupuncture therapy, including group acupuncture, is feasible and effective, and specifically so for underserved and diverse populations at risk for health outcome disparities. Acupuncture therapy also encourages patient engagement and activation. As chronic pain improves, there is a natural progression to want and need to increase activity and movement recovery. Diverse movement approaches are important for improving range of motion, maintaining gains, strengthening, and promoting patient engagement and activation. Yoga therapy is an active therapy with proven benefit in musculoskeletal pain disorders and pain associated disability. The aim of this quasi-experimental pilot feasibility trial is to test the bundling of these 2 effective care options for chronic pain, to inform both the design for a larger randomized pragmatic effectiveness trial as well as implementation strategies across underserved settings.

Knee kinematics of severe medial knee osteoarthritis showed tibial posterior translation and external rotation: a cross-sectional study

BACKGROUND

Knee osteoarthritis (OA) gradually reduces knee function and limits activities of daily living with age. However, the progression of abnormal kinematics of the knee in knee OA is unclear.

AIMS

This study aimed to clarify the relationship between stage of knee OA and abnormal knee kinematics and to identify a strategy for prevention of knee OA.

METHODS

A total of 112 knees of 99 patients (45 men/54 women; 55.9 ± 18.2 years), comprising 28 (27/1) in Kellgren-Lawrence grade 0, 18 (8/10) in grade 1, 27 (2/25) in grade 2, 28 (6/22) in grade 3, and 11 (3/8) in grade 4, were enrolled in this cross-sectional study. In vivo knee kinematics was obtained using a three-dimensional-to-two-dimensional registration technique utilizing CT-based bone models and lateral fluoroscopy during knee extension-flexion in an upright sitting position and squatting.

RESULTS

The external rotation angle of the tibia relative to the femur was greater in grade 3/4 knees than in grade 0/1 knees and tibial posterior translation was greater in grade 3/4 knees than in grade 0-2 knees.

DISCUSSION

Age-related changes in muscle activity and joint instability are considered to be the cause of these abnormal kinematics.

CONCLUSIONS

As the stage of knee OA progresses, there was a tendency toward increasing tibial external rotation and tibial posterior translation during knee extension-flexion in sitting position and squatting. Prevention of the progress of the abnormal knee kinematics may prevent the progression of the knee OA.

Research Trends of Acupuncture Therapy on Knee Osteoarthritis from 2010 to 2019: A Bibliometric Analysis

Background

Acupuncture has been widely applied to relieve knee osteoarthritis (KOA) in many countries. However, the bibliometric analysis of the global use of acupuncture on KOA is largely unknown. Therefore, this study aimed to explore the current status and trends of the global use of acupuncture on KOA in recent 10 years by using CiteSpace (5.6.R3).

Methods

Publications regarding acupuncture therapy for treating KOA between 2010 and 2019 were extracted from the Web of Science database. CiteSpace was used to analyze the number of publications, countries, institutions, journals, authors, cited references and keywords by using standard bibliometric indicators.

Results

A total of 343 publications were retrieved from 2010 to 2019. The total number of publications continually increased over the past four years, and the most active journals, countries, institutions and authors in the field of acupuncture therapy on patients with KOA were identified. The Evid Based Complement Alternat Med (28) was the most prolific journal, and the Ann Intern Med (202) was the most cited journal. The most productive country and institution in this field was China (115) and University of York (18), respectively. Hugh Macpherson (18) was the most prolific author and Witt C ranked the first in the cited authors. In the ranking of frequency in cited reference, the first article was published by Scharf HP (54). The keyword of ‘randomized controlled trial’ ranked first for research developments with the highest citation burst (3.9486). Besides, there were three main frontiers in keywords for KOA research, including ‘research method, ‘age’ and ‘measure of intervention’.

Conclusion

The findings from this bibliometric study provide current status and trends in clinical research of acupuncture therapy on patients with KOA over the past ten years, which may help researchers identify hot topics and explore new directions for future research in this field.

Acupuncture in persons with an increased stress level-Results from a randomized-controlled pilot trial

Background

In today’s Western societies a high percentage of people experience increased or chronic stress. Acupuncture could serve as treatment for persons affected adversely by the increased stress.

Methods

The AkuRest study was a two-centre randomized controlled pilot study in adult persons with increased stress levels. Participants were randomly allocated to one of three groups: verum acupuncture treatment, sham acupuncture, and a waiting control group. The feasibility of the study was assessed. In addition, effects on stress level (measured by the Perceived Stress Questionnaire (PSQ-20)) and other variables were assessed at the end of treatment and a 3-month follow-up.

Results

Altogether, N = 70 persons were included in the study. At the end of the treatment 15.7% were lost to follow-up. The adherence to the protocol was good: 82.9% of the participants completed 100% of their treatment. The stress level of the participants was high at baseline (mean PSQ-20 score 75.5, SD = 8.2). Effect sizes (ES) at T1 showed that verum and sham acupuncture were superior to the waiting condition in reducing stress (ES (verum) = -1.39, 95%-CI = [-2.11; -0.67]: ES (sham) = -1.12, CI = [-1.78;-0.44]). At follow-up, effect sizes were in favour of the verum group (as compared to sham). However, confidence intervals and t-tests showed that these differences were not significant.

Conclusion

The pilot study demonstrated the feasibility of the acupuncture RCT in persons with increased stress levels. Estimated parameters can be used to design a larger RCT to prove the–here indicated—efficacy of verum acupuncture to decrease stress.

Effectiveness of a novel hydrolyzed collagen formulation in treating patients with symptomatic knee osteoarthritis: a multicentric retrospective clinical study

PURPOSE

Knee osteoarthritis (OA) is a musculoskeletal disorder that may have a heavy impact on the patients' quality of life. Intra-articular collagen injection may be a safe adjuvant. Recently, CHondroGrid (CG), a hydrolyzed (< 3 kDa) bovine collagen injectable formulation, has been placed on the market. The aim of this study was to investigate the safety and performance profile of CG.

METHODS

Patients affected by Kellgren Lawrence grade 1 to 4 knee OA and BMI < 30 were treated by administering three CG injections of 2 ml (4 mg) each (at 15 days and 45 days from the first one, respectively) and were followed up for six months after the last administration. Clinical records were retrospectively assessed to compare VAS, Lequesne and WOMAC total, pain, stiffness, and physical function scores collected at baseline and 15, 45, and 225 days after the first injection.

RESULTS

At the last follow-up, 70 patients (37 men and 33 women, aged 57.1 ± 14.5 years) treated with CG showed a 50% reduction in their median Lequesne score, a 50% reduction in their VAS score at rest and moving, and a ≥ 50% reduction for all other scores under consideration.

CONCLUSIONS

CG may be a safe and effective adjuvant in the treatment of symptomatic knee OA.

A scoping review of network meta-analyses assessing the efficacy and safety of complementary and alternative medicine interventions

BACKGROUND

Network meta-analysis (NMA) has rapidly grown in use during the past decade for the comparison of healthcare interventions. While its general use in the comparison of conventional medicines has been studied previously, to our awareness, its use to assess complementary and alternative medicines (CAM) has not been studied. A scoping review of the literature was performed to identify systematic reviews incorporating NMAs involving one or more CAM interventions.

METHODS

An information specialist executed a multi-database search (e.g., MEDLINE, Embase, Cochrane), and two reviewers performed study selection and data collection. Information on publication characteristics, diseases studied, interventions compared, reporting transparency, outcomes assessed, and other parameters were extracted from each review.

RESULTS

A total of 89 SR/NMAs were included. The largest number of NMAs was conducted in China (39.3%), followed by the United Kingdom (12.4%) and the United States (9.0%). Reviews were published between 2010 and 2018, with the majority published between 2015 and 2018. More than 90 different CAM therapies appeared at least once, and the median number per NMA was 2 (IQR 1-4); 20.2% of reviews consisted of only CAM therapies. Dietary supplements (51.1%) and vitamins and minerals (42.2%) were the most commonly studied therapies, followed by electrical stimulation (31.1%), herbal medicines (24.4%), and acupuncture and related treatments (22.2%). A diverse set of conditions was identified, the most common being various forms of cancer (11.1%), osteoarthritis of the hip/knee (7.8%), and depression (5.9%). Most reviews adequately addressed a majority of the PRISMA NMA extension items; however, there were limitations in indication of an existing review protocol, exploration of network geometry, and exploration of risk of bias across studies, such as publication bias.

CONCLUSION

The use of NMA to assess the effectiveness of CAM interventions is growing rapidly. Efforts to identify priority topics for future CAM-related NMAs and to enhance methods for CAM comparisons with conventional medicine are needed.

Individual vs. Group Delivery of Acupuncture Therapy for Chronic Musculoskeletal Pain in Urban Primary Care-a Randomized Trial

BACKGROUND

Acupuncture has been shown to be effective for the treatment of chronic musculoskeletal back, neck, and osteoarthritis pain. However, access to acupuncture treatment has been limited in medically underserved and low-income populations.

OBJECTIVE

Acupuncture therapy delivered in groups could reduce cost and expand access. We compared the effectiveness of group versus individual acupuncture for pain and function among ethnically diverse, low-income primary care patients with chronic musculoskeletal pain.

DESIGN

This was a randomized comparative effectiveness non-inferiority trial in 6 Bronx primary care community health centers. Participants with chronic (> 3 months) back, neck, or osteoarthritis pain were randomly assigned to individual or group acupuncture therapy for 12 weeks.

PARTICIPANTS

Seven hundred seventy-nine participants were randomized. Mean age was 54.8 years. 35.3% of participants identified as black and 56.9% identified as Latino. Seventy-six percent were Medicaid insured, 60% reported poor/fair health, and 37% were unable to work due to disability.

INTERVENTIONS

Participants received weekly acupuncture treatment in either group or individual setting for 12 weeks.

MAIN MEASURES

Primary outcome was pain interference on the Brief Pain Inventory at 12 weeks; secondary outcomes were pain severity (BPI), physical and mental well-being (PROMIS-10), and opiate use. Outcome measures were collected at baseline, 12 and 24 weeks.

KEY RESULTS

37.5% of individual arm and 30.3% in group had > 30% improvement in pain interference (d = 7.2%, 95% CI - 0.6%, 15.1%). Non-inferiority of group acupuncture was not demonstrated for the primary outcome assuming a margin of 10%. In the responder analysis of physical well-being, 63.1% of individual participants and 59.5% of group had clinically important improvement at 12 weeks (d = 3.6%, 95% CI - 4.2%, 11.4%).

CONCLUSIONS

Both individual and group acupuncture therapy delivered in primary care settings reduced chronic pain and improved physical function at 12 weeks; non-inferiority of group was not shown.

An updated algorithm recommendation for the management of knee osteoarthritis from the European Society for Clinical and Economic Aspects of Osteoporosis, Osteoarthritis and Musculoskeletal Diseases (ESCEO)

OBJECTIVES

The European Society for Clinical and Economic Aspects of Osteoporosis, Osteoarthritis and Musculoskeletal Diseases (ESCEO) sought to revisit the 2014 algorithm recommendations for knee osteoarthritis (OA), in light of recent efficacy and safety evidence, in order to develop an updated stepwise algorithm that provides practical guidance for the prescribing physician that is applicable in Europe and internationally.

METHODS

Using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) process, a summary of evidence document for each intervention in OA was provided to all members of an ESCEO working group, who were required to evaluate and vote on the strength of recommendation for each intervention. Based on the evidence collected, and on the strength of recommendations afforded by consensus of the working group, the final algorithm was constructed.

RESULTS

An algorithm for management of knee OA comprising a stepwise approach and incorporating consensus on 15 treatment recommendations was prepared by the ESCEO working group. Both "strong" and "weak" recommendations were afforded to different interventions. The algorithm highlights the continued importance of non-pharmacological interventions throughout the management of OA. Benefits and limitations of different pharmacological treatments are explored in this article, with particular emphasis on safety issues highlighted by recent literature analyses.

CONCLUSIONS

The updated ESCEO stepwise algorithm, developed by consensus from clinical experts in OA and informed by available evidence for the benefits and harms of various treatments, provides practical, current guidance that will enable clinicians to deliver patient-centric care in OA practice.

A systematic review of economic evaluations of conservative treatments for chronic lower extremity musculoskeletal complaints

Objective

The aim was to appraise and synthesize studies evaluating the clinical and cost effectiveness of conservative interventions for chronic lower extremity musculoskeletal (MSK) conditions and describe their characteristics, including the type of economic evaluation, primary outcomes and which conditions.

Methods

The search strategy related to economic evaluations of lower limb MSK conditions that used conservative therapies. Eight electronic databases were searched (CENTRAL, MEDLINE, PubMed, EMBASE, CINAHL, PEDro, NHSEED and Proquest), as were the reference lists from included articles. The quality of articles was appraised using a modified version of the economic evaluations’ reporting checklist (economic) and The Cochrane Collaboration’s tool for assessing risk of bias (clinical).

Results

Twenty-six studies were eligible and included in the review. Economic evaluations of conservative interventions for OA or pain affecting the knee/hip (n = 25; 93%) were most common. The main approaches adopted were cost–utility analysis (n = 17; 68%) or cost–effectiveness analysis (n = 5; 19%). Two studies involved interventions including footwear/foot orthoses; for heel pain (n = 1; 4%) and overuse injuries (n = 1; 4%). Fifty per cent of economic evaluations adopted the EQ-5D-3L as the primary outcome measure for quality of life and quality-adjusted life year calculations.

Conclusion

Economic evaluations have been conducted largely for exercise-based interventions for MSK conditions of the hip and knee. Few economic evaluations have been conducted for other clinically important lower limb MSK conditions. A matrix presentation of costs mapped with outcomes indicated increasing costs with either no difference or improvements in clinical effectiveness. The majority of economic evaluations were of good reporting quality, as were the accompanying clinical studies.

Évaluer les psychothérapies durant et après un cancer

Il est couramment admis que les bénéfices d’une psychothérapie sur la santé psychique et la qualité de vie dépendent du psychologue, du patient et de la qualité de leur relation. Si ces observations restent vraies, de récentes études interventionnelles montrent que la méthode psychothérapeutique utilisée compte autant, et de plus en plus au fil des séances. L’article invite les psychothérapeutes à contribuer davantage aux études interventionnelles d’efficience et d’implémentation pour améliorer les pratiques spécifiques en oncologie, pour garantir le respect de la subjectivité, pour optimiser les bénéfices des patients et pour mieux se différencier de pratiques non pertinentes, voire dangereuses, propagées par des professionnels de santé, des réseaux sociaux ou des médias sous influence.

Acupuncture for the treatment of lower limb diabetic peripheral neuropathy: a systematic review

OBJECTIVE

To examine evidence for acupuncture interventions in the management of diabetes-related peripheral neuropathy (DPN) symptoms.

METHODS

Five electronic databases were searched up to June 2017 for studies that included participants with symptoms of DPN, used an acupuncture intervention, and reported before-and-after DPN-related outcome measures. Two reviewers independently performed the data extraction. The level of homogeneity was assessed, and studies were appraised using the Cochrane Risk of Bias tool, the STRICTA guidelines for acupuncture reporting and the NICMAN scale for acupuncture quality.

RESULTS

Ten studies with 432 participants were included: three randomised controlled trials (RCTs), two pilot RCTs, three uncontrolled clinical trials, one quasi-RCT and one prospective case series. Improvements in DPN pain symptoms were reported by all studies. Heterogeneity of outcome measures prevented a meta-analysis. Variations were found in needle retention time and point selection, as well as total number and frequency of treatments. Common acupuncture point selections were ST36 and SP6. Half of the studies used local point selection. Studies conducted outside China had better acupuncture reporting and quality according to the STRICTA checklist and NICMAN scales, respectively. Risk of bias was high or unclear in the majority of studies for all domains except attrition bias.

CONCLUSIONS

Acupuncture for DPN appears to improve symptoms. However, the application of acupuncture varies greatly, and the quality of included studies was generally low. Available studies have varying methodologies and different outcome measures. Further, suitably powered studies using appropriate DPN outcome measures are required.

Acupuncture Therapy in a Group Setting for Chronic Pain

Objective

This project was designed to test the feasibility and effectiveness of acupuncture therapy given in a group setting for chronic pain.

Design

Nonrandomized, repeated measures quasi-experimental trial.

Setting

Care was delivered in a primary care clinic waiting area after clinic hours.

Subjects

Included were primary care patients (≥18 years old) with chronic pain of the neck, back, shoulder, or osteoarthritis of any site of at least three months' duration.

Methods

Subjects received eight weekly acupuncture therapy sessions in a group setting. Acupuncture therapy included a combination of palpation, acupuncture needling, Tui na, Gua sha, and auricular treatment. Baseline pain levels were established in a two- to four-week run-in; assessment of the intervention impact on pain intensity, mood, and functional status were made at the end of the treatment period (eight weeks) and 16 weeks after completion of intervention (24 weeks).

Results

Of the total 113 participants recruited for the trial, 96 completed the 24-week protocol. We found a statistically and clinically significant decrease in pain severity, pain interference, and depression in our study population. There were no serious adverse events.

Conclusions

Acupuncture therapy offered in the group setting was effective in reducing pain severity, pain interference, and depression in patients with chronic neck, back, or shoulder pain or osteoarthritis. Benefit persisted through the 24-week measure despite no additional treatment. This finding has potentially important implications for improving access to effective acupuncture treatment for patients with limited financial resources.

Twelve-month analgesia and rescue, by cooled radiofrequency ablation treatment of osteoarthritic knee pain: results from a prospective, multicenter, randomized, cross-over trial

BACKGROUND AND OBJECTIVES

As a follow-up to the 6-month report,12 this study investigated the analgesic effect of cooled radiofrequency ablation (CRFA) in patients with knee osteoarthritis (OA) 12 months postintervention and its ability to provide pain relief in patients who experienced unsatisfactory effects of intra-articular steroid injection (IAS).

METHODS

Seventy-eight per cent (52/67) of patients originally treated with CRFA were evaluated at 12 months, while at 6 months post-IAS, 82% (58/71) of those patients crossed over to CRFA and assessed 6 months later.

RESULTS

At 12 months, 65% of the original CRFA group had pain reduction ≥50%, and the mean overall drop was 4.3 points (p<0.0001) on the numeric rating scale. Seventy-five per cent reported 'improved' effects. The cross-over group demonstrated improvements in pain and functional capacity (p<0.0001). No unanticipated adverse events occurred.

CONCLUSIONS

This study demonstrates that analgesia following CRFA for OA knee pain could last for at least 12 months and could rescue patients who continue to experience intolerable discomfort following IAS.

CLINICAL TRIAL REGISTRATION

The ClinicalTrials.gov registration number for this study is NCT02343003.

Structured Education and Neuromuscular Exercise Program for Hip and/or Knee Osteoarthritis: A Health Technology Assessment

BACKGROUND

Osteoarthritis is a chronic disorder and the most common form of arthritis. The joints most commonly affected are the hip and knee. The progression of osteoarthritis results in the breakdown of tissues and cartilage and the loss of joint function, causing symptoms such as pain, stiffness, reduced physical function, and limited movement. Although there is no cure for osteoarthritis, treatment options are available to manage symptoms and optimize quality of life. Clinical guidelines recommend education, exercise, and weight loss (when necessary) as the first line of treatment.

METHODS

We conducted a health technology assessment, which included an evaluation of the effectiveness, safety, and cost-effectiveness of a structured education and neuromuscular exercise program for the management of hip and/or knee osteoarthritis. We also assessed the budget impact of publicly funding such a program, and we spoke with people with osteoarthritis to gain an understanding of their preferences and values. We performed a systematic review of the clinical and economic literature published between January 1, 2008, and October 4, 2017. We also performed a grey literature search of health technology assessment websites. We assessed the risk of bias of each study, and we assessed the quality of the body of evidence according to the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) Working Group criteria. To evaluate the cost-effectiveness of a structured education and neuromuscular exercise program for adults with knee osteoarthritis, we conducted a cost-utility analysis from the perspective of the Ontario Ministry of Health and Long-Term Care. We also estimated the budget impact of publicly funding such a program in Ontario over the next 5 years. To contextualize the potential value of this type of program as a treatment option, we spoke with people with hip and/or knee osteoarthritis.

RESULTS

Ten studies met our inclusion criteria for the clinical evidence review. Compared with usual care, a structured education and neuromuscular exercise program showed statistically significant short-term improvements in pain (GRADE low) and physical function (GRADE moderate), as well as statistically significant long-term improvements in performing activities of daily living (GRADE moderate) and in quality of life (GRADE moderate). The short-term improvements in pain and physical function appeared to be sustained into the medium term. Compared with patient education, a structured education and neuromuscular exercise program showed statistically significant short-term improvements in pain (GRADE low) and physical function (GRADE low) and sustained long-term improvement in physical function.Our primary economic evaluation showed that, compared with usual care, a group-based structured education and neuromuscular exercise program consisting of two educational sessions and 24 exercise sessions for the management of knee osteoarthritis was associated with an incremental cost of $719 (95% confidence interval [CI]: $410-$1,118) and an incremental quality-adjusted survival of 0.03 quality-adjusted life-years (QALYs) (95% CI: -0.006 to 0.06), resulting in an incremental cost-effectiveness ratio (ICER) of $23,967 per QALY gained. The budget impact of publicly funding a group-based structured education and neuromuscular exercise program consisting of two educational sessions and 24 exercise sessions would range from $21.4 million to $91.6 million per year over the next 5 years. The budget impact of publicly funding a program consisting of two educational sessions and 12 exercise sessions would range from $12.4 million to $53.2 million per year over the next 5 years.People with hip and/or knee osteoarthritis with whom we spoke reported on the negative impact of osteoarthritis on their physical functioning and quality of life. Those with experience of a structured education and neuromuscular exercise program reported favourably on the program, stating they felt that participation in the program had strengthened their muscles and reduced the negative impact of their symptoms. The cost of such programs was reported as a barrier to access.

CONCLUSIONS

There is moderate-quality evidence that, compared with usual care, a structured education and neuromuscular exercise program improves physical function, quality of life, and the ability to perform activities of daily living. There is low-quality evidence that, compared with usual care, this type of program improves pain. Low-quality evidence suggests that, compared with patient education, a structured education and neuromuscular exercise program improves pain and physical function.A group-based structured education and neuromuscular exercise program may be cost-effective for the nonsurgical management of knee osteoarthritis. Publicly funding a group-based structured education and neuromuscular exercise program for hip and/or knee osteoarthritis in Ontario would lead to additional costs to the health system of $21.4 million to $91.6 million per year over the next 5 years. If the program could be delivered with a smaller number of 12 exercise sessions, the budget impact would be reduced to between $12.4 million and $53.2 million over the next 5 years.Structured education and neuromuscular exercise programs are perceived favourably by people with hip and/or knee osteoarthritis. However, the cost of such programs may be a barrier to access.

Cost Savings from Reducing Pain Through the Delivery of Integrative Medicine Program to Hospitalized Patients

OBJECTIVES

An important task facing hospitals is improving pain management without raising costs. Integrative medicine (IM), a promising nonpharmacologic pain management strategy, is yet to be examined for its cost implications in an inpatient setting. This institution has had an inpatient IM department for over a decade. The purpose was to examine the relationship between changes in patients' pain, as a result of receiving IM therapy, and total cost of care during an inpatient hospital admission.

DESIGN

In this retrospective analysis, data from an EPIC-based electronic health record (EHR) patient demographics, length of stay (LOS), and All Patient Refined Diagnosis Related Groups (APR-DRG) severity of illness measures were utilized. IM practitioners collected and entered patient-reported pain scores into the EHR. The authors regressed the demographic, change in pain, LOS, and APR-DRG variables with changes in pain on total cost for the hospital admission. To estimate cost savings to the hospital, they computed the average reduction in cost associated with reduction in pain by multiplying the coefficient for change in pain by average total cost.

SETTING/LOCATION

A large, tertiary care hospital in Minneapolis, MN.

SUBJECTS

Adult inpatient admissions, 2730, during the study period where patients received IM for pain and met eligibility criteria.

INTERVENTION

IM services provided to inpatients.

OUTCOME MEASURES

Change in pain on an 11-point numeric rating scale before and after initial IM sessions; total costs for hospital admissions.

RESULTS

Both LOS and age were found to increase cost, as did being white, male, married, and having APR-DRG severity coded as extreme. For patients receiving IM therapies, pain was reduced by an average of 2.05 points and this pain reduction was associated with a cost savings of $898 per hospital admission.

CONCLUSIONS

For patients receiving IM therapies, pain was significantly reduced and costs were lowered by about 4%.

Cost-utility of a six-month programmed sports therapy (PST) in patients with haemophilia

INTRODUCTION

Recurrent musculoskeletal haemorrhages in people with haemophilia (PwH) lead to restrictions in the locomotor system and, as a result, in physical performance, too. Due to its physical and psychological benefits, sport is increasingly re-commended for haemophilic patients. Evidence on the cost-effectiveness of sports therapy is still lacking.

AIM

The aim of this study was to determine the cost-effectiveness of a 6-month programmed sports therapy (PST).

METHODS

The cost-effectiveness of the 6-month PST was assessed from a societal perspective alongside a RCT using cost-utility analysis. The analysis included 50 PwH with moderate-to-severe haemophilia A and B and a training period over 6 months. The health-related quality of life was measured with the EuroQoL-domain questionnaire. Resource utilization was assessed by questionnaire before and after the intervention. A cost-effectiveness acceptability curve was constructed, and sensitivity analyses were performed.

RESULTS

During the 6-month study period, mean adjusted total healthcare costs were lower (mean difference: -22 805 EUR; 95%-CI: -73 944-48 463; P = .59) and the number of QALYs was higher in the intervention group (mean difference: 0.3733; 95%-CI: 0.0014-0.0573; P = .04). The probability of an incremental cost-effectiveness ratio <50 000 EUR per QALY was 71%. The performed sensitivity analysis confirmed these results.

CONCLUSION

Results showed that the PST is effective in terms of a significant gain of QALYs. Furthermore, results weakly indicate the potential of the PST to reduce healthcare costs. Future studies should expand the observation period to have a closer look at the influence of PST on lifetime costs.

Evidence-Based Nonpharmacologic Strategies for Comprehensive Pain Care: The Consortium Pain Task Force White Paper

Medical pain management is in crisis; from the pervasiveness of pain to inadequate pain treatment, from the escalation of prescription opioids to an epidemic in addiction, diversion and overdose deaths. The rising costs of pain care and managing adverse effects of that care have prompted action from state and federal agencies including the DOD, VHA, NIH, FDA and CDC. There is pressure for pain medicine to shift away from reliance on opioids, ineffective procedures and surgeries toward comprehensive pain management that includes evidence-based nonpharmacologic options. This White Paper details the historical context and magnitude of the current pain problem including individual, social and economic impacts as well as the challenges of pain management for patients and a healthcare workforce engaging prevalent strategies not entirely based in current evidence. Detailed here is the evidence-base for nonpharmacologic therapies effective in postsurgical pain with opioid sparing, acute non-surgical pain, cancer pain and chronic pain. Therapies reviewed include acupuncture therapy, massage therapy, osteopathic and chiropractic manipulation, meditative movement therapies Tai chi and yoga, mind body behavioral interventions, dietary components and self-care/self-efficacy strategies. Transforming the system of pain care to a responsive comprehensive model necessitates that options for treatment and collaborative care must be evidence-based and include effective nonpharmacologic strategies that have the advantage of reduced risks of adverse events and addiction liability. The evidence demands a call to action to increase awareness of effective nonpharmacologic treatments for pain, to train healthcare practitioners and administrators in the evidence base of effective nonpharmacologic practice, to advocate for policy initiatives that remedy system and reimbursement barriers to evidence-informed comprehensive pain care, and to promote ongoing research and dissemination of the role of effective nonpharmacologic treatments in pain, focused on the short- and long-term therapeutic and economic impact of comprehensive care practices.
