Effectiveness of Models Used to Deliver Multimodal Care for Chronic Musculoskeletal Pain: a Rapid Evidence Review

A Systematic Review of Chronic Pain Management Interventions Among Veterans of Recent Wars and Armed Conflicts

OBJECTIVES

To identify chronic pain management strategies aimed to reduce pain intensity and enhance functional outcomes in veterans of wars and armed conflict.

DESIGN

Systematic review without meta-analysis.

DATA SOURCES

Key words "chronic pain," "veterans," and "injuries" were used to search for articles in the MEDLINE, CINAHL, APA PsycInfo, and Embase databases. Articles published in English between 2000 and 2023 were included.

REVIEW/ANALYSIS METHODS

A systematic literature search was conducted in June 2020, updated in April 2023, and managed using Covidence review software. Inclusion criteria focused on combat-injured veterans with chronic pain, excluding nonveterans and civilians treated for acute or chronic pain. Data from included studies were extracted, summarized, and critically appraised using the 2018 Mixed Methods Appraisal Tool. This review is registered with PROSPERO (CRD42020207435).

RESULTS

Fourteen studies met the inclusion criteria, with 10 of them supporting nonpharmacological approaches for managing chronic pain among veterans of armed conflicts and wars. Interventions included psychological/behavioral therapies, peer support, biofeedback training via telephone-based therapy, manual therapy, yoga, cognitive processing therapy, cognitive-behavioral therapy, and social and community integration to reduce pain intensity and enhance functional outcomes.

CONCLUSION

Nonpharmacological treatments for chronic pain have increased in recent years, a shift from earlier reliance on pharmacological treatments. More evidence from randomized controlled trials on the benefits of combined pain interventions could improve pain management of veterans with complex care needs.

Physiotherapeutic and non-conventional approaches in patients with chronic low-back pain: a level I Bayesian network meta-analysis

Chronic low back pain (cLBP) is a major cause of disability and healthcare expenditure worldwide. Its prevalence is increasing globally from somatic and psychosocial factors. While non-pharmacological management, and in particular physiotherapy, has been recommended as a first-line treatment for cLBP, it is not clear what type of physiotherapeutic approach is the most effective in terms of pain reduction and function improvement. This analysis is rendered more difficult by the vast number of available therapies and a lack of a widely accepted classification that can effectively highlight the differences in the outcomes of different management options. This study was conducted according to the PRISMA guidelines. In January 2024, the following databases were accessed: PubMed, Web of Science, Google Scholar, and Embase. All the randomised controlled trials (RCTs) which compared the efficacy of physiotherapy programs in patients with cLBP were accessed. Studies reporting on non-specific or mechanical cLPB were included. Data concerning the Visual Analogic Scale (VAS) or numeric rating scale (NRS), Roland Morris Disability Questionnaire (RMQ) and Oswestry Disability Index (ODI). Data from 12,773 patients were collected. The mean symptom duration was 61.2 ± 51.0 months and the mean follow-up was 4.3 ± 5.9 months. The mean age was 44.5 ± 9.4 years. The mean BMI was 25.8 ± 2.9 kg/m2. The Adapted Physical Exercise group evidenced the lowest pain score, followed by Multidisciplinary and Adapted Training Exercise/Complementary Medicine. The Adapted Physical Exercise group evidenced the lowest RMQ score followed by Therapeutic Exercises and Multidisciplinary. The Multidisciplinary group evidenced the lowest ODI score, followed by Adapted Physical Exercise and Physical Agent modalities. Within the considered physiotherapeutic and non-conventional approaches to manage nonspecific and/or mechanic cLBP, adapted physical exercise, physical agent modalities, and a multidisciplinary approach might represent the most effective strategy to reduce pain and disability.

Mapping the Design Space of Technology-Based Solutions for Better Chronic Pain Care: Introducing the Pain Tech Landscape

OBJECTIVES

Technology has substantial potential to transform and extend care for persons with chronic pain, a burdensome and costly condition. To catalyze the development of impactful applications of technology in this space, we developed the Pain Tech Landscape (PTL) model, which integrates pain care needs with characteristics of technological solutions.

METHODS

Our interdisciplinary group representing experts in pain and human factors research developed PTL through iterative discussions. To demonstrate one potential use of the model, we apply data generated from a narrative review of selected pain and technology journals (2000-2020) in the form of heat map overlays, to reveal where pain tech research attention has focused to date.

RESULTS

The PTL comprises three two-dimensional planes, with pain care needs on each x axis (measurement to management) and technology applications on the y axes according to a) user agency (user- to system-driven), b) usage time frame (temporary to lifelong), and c) collaboration (single-user to collaborative). Heat maps show that existing applications reside primarily in the "user-driven/management" quadrant (e.g., self-care apps). Examples of less developed areas include artificial intelligence and Internet of Things (i.e., Internet-linked household objects), and collaborative/social tools for pain management.

CONCLUSIONS

Collaborative development between the pain and tech fields in early developmental stages using the PTL as a common language could yield impactful solutions for chronic pain management. The PTL could also be used to track developments in the field over time. We encourage periodic reassessment and refinement of the PTL model, which can also be adapted to other chronic conditions.

Additional effect of pain neuroscience education to spinal manipulative therapy on pain and disability for patients with chronic low back pain: a randomized controlled trial

BACKGROUND

Spinal manipulative therapy (SMT) demonstrates small effects on pain intensity in low back pain. Combining SMT with a psychosocial intervention like pain neuroscience education (PNE) could promote additional effect.

OBJECTIVES

To evaluate the additional effect of PNE when combined to SMT on pain intensity and low back pain-related disability in patients with chronic low back pain (CLBP).

METHOD

One hundred and four patients with CLBP of both sexes aged between 18 and 55 years were treated with PNE + SMT compared to SMT alone. The primary outcome measures were pain intensity and disability post-treatment (4 weeks). Secondary outcomes were fear-avoidance beliefs, global perceived effect of improvement, and pain self-efficacy. Results were obtained immediately post-treatment and at three follow-ups (30-days, 90-days, and 180-days).

RESULTS

No significant between-group difference was observed for pain intensity and disability post-treatment. In contrast, our results showed a significantly longer additional effect for the group treated with SMT + PNE for the following outcomes: pain intensity (change baseline to 90 day follow-up = -0.90 [95% CI= -1.76, -0.4] and change baseline to 180 day follow-up = -1.19 [95% CI= -2.06, -0.32]) and low back pain-related disability, global perceived effect of improvement and pain self-efficacy (180th day follow-up).

CONCLUSION

The results of this trial suggest the addition of PNE to SMT did not bring any additional effect on pain intensity and disability in the short term, but SMT + PNE can result in longer-lasting effects in patients with CLBP and that such an effect could be related to a possible mediator effect of pain self-efficacy.

The Role of Environmental Context and Physical Activity in Prescribed Opioid Use and Pain in Daily Life among Patients With Chronic Low Back Pain

BACKGROUND

Prescription opioids remain a primary treatment option for patients with chronic low back pain. However, little research has examined how patients take opioids in daily life. Behavioral economics suggest that the environmental context may contribute to patients' decisions around opioid use.

PURPOSE

This study examined the association of self-reported environmental factors and physical activity with likelihood of taking opioids, opioid dosage, and physical pain.

METHOD

Patients with chronic low back pain on long-term opioid therapy (n = 34) without significant past-year opioid-related problems completed a two-week ecological momentary assessment protocol (nobservations = 1,714).

RESULTS

Initial multilevel models revealed multiple associations for different specific contexts with opioid use and pain. In models that collapsed specific contexts into categories (where, with whom, doing what), greater occasion-level physical activity was associated with a greater likelihood of taking opioids and greater pain, and being somewhere (v. at home) was associated with taking a smaller opioid dose. At any given occasion, being with someone (v. alone) was associated with taking a larger opioid dose, but patients who spent more time with others over the entire study took fewer opioids overall. Multilevel mediation found that pain did not mediate the association of physical activity and opioid use.

CONCLUSION

Results suggest that prescribed opioid use in patients with chronic low back pain is not solely determined by pain, but influenced by environmental factors, including physical activity. Psychoeducation regarding environmental factors, including how factors may be associated with both increased and decreased use of opioids, may help patients take fewer opioids more effectively.

Home-Based Health Care Interventions for People Aged 75 Years and Above With Chronic, Noninflammatory Musculoskeletal Pain: A Scoping Review

BACKGROUND AND PURPOSE

Chronic, noninflammatory musculoskeletal pain is common in the aged population and management can be challenging for older people due to multimorbidity, social isolation, and physical frailty. The aim of this scoping review is to summarize and discuss the evidence related to home-based health care interventions for older adults, with chronic, musculoskeletal pain.

METHODS

A review of the literature using 8 electronic databases (Embase, MEDLINE, CINAHL, PubMed, Cochrane Library, Physiotherapy Evidence Database [PEDro], Scopus, and Web of Science) was performed, following the PRISMA-ScR guidelines. English language published studies that assessed home-based health care intervention/s, in men and women 75 years and older, with chronic, noninflammatory musculoskeletal pain where included. Two authors independently reviewed the articles and extracted data into a preformulated chart.

RESULTS AND DISCUSSION

The database search identified 4722 studies of which 7 studies met the inclusion criteria. Six of the 7 studies were randomized controlled trials and 5 studies focused on a single-site pain. The type of home-based interventions in the included studies was physical therapy (n = 2), psychotherapy (n = 3), and multimodal therapy (combination of multiple therapies) (n = 2). Participation completion rate was more than 74% in 6 out of 7 studies. Most studies used pain and/or physical function as their primary outcome (n = 6). Music therapy showed a statistically significant reduction in visual analog scale score for pain, and there was a trend toward improvement of pain and function in the physical therapy studies. No significant differences in outcomes between intervention and control groups were observed in the multimodal studies.

CONCLUSION

This review highlights the scarcity of evidence related to home-based health interventions in older people 75 years and older, living with chronic, noninflammatory musculoskeletal pain. The findings were that physical, psychotherapeutic, and multimodal interventions are usually well tolerated and can be delivered as a safe self-management option. There remains a substantial need for more high-quality research with wider range of home-based interventions and comprehensive assessment of outcomes for this age group.

Systematic review of the efficacy, effectiveness, and cost-effectiveness of stepped-care interventions for the prevention and treatment of problematic substance use

BACKGROUND

Stepped-care is a commonly recommended and implemented care model across health care domains, including substance use. Despite their presumed efficient allocation of treatment resources, a current and robust evidence synthesis is needed on the efficacy, effectiveness and cost-effectiveness of stepped-care for substance use.

METHODS

This systematic review analyzed articles describing evaluations of stepped-care models that measured the use of acutely psychoactive substances (i.e., alcohol, cannabis, hallucinogens, inhalants, opioids, sedatives, hypnotics, anxiolytics, and stimulants) as a primary or secondary outcome, in participants over 18 years old. The analysis investigated model and participant characteristics associated with treatment outcomes.

RESULTS

The study team conducted a search of five databases of literature (PsychINFO, MEDLINE, Embase, Cochrane Library and Scopus) published between January 1, 2010, and November 1, 2020. The search yielded 1051 unique articles, 19 of which were included in the analysis. The studies had considerable variability in sample sizes (n = 18-2310), time to follow-up (4.5 months to 3 years), and retention rates (35.1-100 %). Studies examined outcomes for either alcohol alone (n = 9), alcohol and other drug use (n = 9), or drug use alone (n = 1). Most studies (n = 13;) were rated as good quality. Three (15.8 %) were rated as fair and three (15.8 %) were rated as poor quality. The evidence regarding the efficacy, effectiveness and cost-effectiveness of stepped-care approaches is limited, but four of seven studies found that adaptive-care interventions delivered in the context of other systemic interventions produced greater benefit than control conditions in relation to at least one alcohol-related outcome. We have insufficient evidence to determine whether the modes or intensity of interventions included in the models, or decision rules used to step people up or down to differing levels of care, have an impact on outcome.

CONCLUSION

Heterogeneity between studies with regard to model and evaluation design limited the degree to which the analysis could draw robust conclusions. Sample recruitment and statistical power are particular challenges, and the field needs more innovative evaluation designs to assess the efficacy, effectiveness, and cost-effectiveness of stepped-care models.

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.

"I Don't Know Why I've Got this Pain!" Allostasis as a Possible Explanatory Model

Explaining the onset and maintenance of pain can be challenging in many clinical presentations. Allostasis encompasses the mechanisms through which humans adapt to stressors to maintain physiological stability. Due to related neuro-endocrine-immune system effects, allostasis and allostatic load (the cumulative effects on the brain and body that develop through the maintenance of physiological stability) offer the potential to explain the development and maintenance of musculoskeletal pain in certain cases. This paper outlines the concept of allostatic load, highlights the evidence for allostatic load in musculoskeletal pain conditions to date, and discusses mechanisms through which allostatic load influences pain, with particular focus on hypothalamic-pituitary-adrenal axis and sympathetic nervous system function and central, brain-driven governance of these systems. Finally, through case examples, consideration is given as to how allostatic load can be integrated into clinical reasoning and how it can be used to help explain pain to individuals and guide clinical decision-making.

IMPACT

Awareness of the concept of allostatic load, and subsequent assessment of physical and psychological stressors potentially contributing to allostatic load, may facilitate a broader understanding of the multidimensional presentations of many people with pain, both acute and persistent. This may facilitate discussion between clinicians and their patients regarding broader influences on their presentations and drive more targeted and inclusive pain management strategies.

Teaming in Interdisciplinary Chronic Pain Management Interventions in Primary Care: a Systematic Review of Randomized Controlled Trials

BACKGROUND

Current pain management recommendations emphasize leveraging interdisciplinary teams. We aimed to identify key features of interdisciplinary team structures and processes associated with improved pain outcomes for patients experiencing chronic pain in primary care settings.

METHODS

We searched PubMed, EMBASE, and CINAHL for randomized studies published after 2009. Included studies had to report patient-reported pain outcomes (e.g., BPI total pain, GCPS pain intensity, RMDQ pain-related disability), include primary care as an intervention setting, and demonstrate some evidence of teamwork or teaming; specifically, they needed to involve at least two clinicians interacting with each other and with patients in an ongoing process over at least two timepoints. We assessed study quality with the Cochrane Risk of Bias tool. We narratively synthesized intervention team structures and processes, comparing among interventions that reported a clinically meaningful improvement in patient-reported pain outcomes defined by the minimal clinically important difference (MCID).

RESULTS

We included 13 total interventions in our review, of which eight reported a clinically meaningful improvement in at least one patient-reported pain outcome. No included studies had an overall high risk of bias. We identified the role of a care manager as a common structural feature of the interventions with some clinical effect on patient-reported pain. The team processes involving clinicians varied across interventions reporting clinically improved pain outcomes. However, when analyzing team processes involving patients, six of the interventions with some clinical effect on pain relied on pre-scheduled phone calls for continuous patient follow-up.

DISCUSSION

Our review suggests that interdisciplinary interventions incorporating teamwork and teaming can improve patient-reported pain outcomes in comparison to usual care. Given the current evidence, future interventions might prioritize care managers and mechanisms for patient follow-up to help bridge the gap between clinical guidelines and the implementation of interdisciplinary, team-based chronic pain care.

The Critical Role of Nutrition Care to Improve Pain Management: A Global Call to Action for Physical Therapist Practice

Physical therapists have unique education in the comprehensive biopsychosocial assessment and treatment of chronic pain and its mechanisms. Recently, physical therapists have raised awareness regarding the impact of nutrition on promoting health and managing noncommunicable diseases. Robust evidence supports the implementation of nutrition in physical therapist education and practice. Of particular interest for the physical therapist are investigations that use dietary interventions for the treatment of chronic pain. Yet physical therapists have received little guidance regarding their role in nutrition care for pain management and may pass on opportunities to counsel their patients on the connection between nutrition and pain. Therefore, a clinical paradigm shift and unified voice within the profession is called on to encourage physical therapists to develop tailored multimodal lifestyle interventions that include nutrition care for the management of chronic pain. This Perspective describes evidence supporting the implementation of nutrition care in physical therapist practice, supports the role of nutritional pain management for physical therapists, and encourages the use of nutrition care for primary, secondary, tertiary, prevention, health promotion, and wellness related to chronic pain. To achieve these aims, this Perspective offers suggestions for how physical therapists can (1) enhance clinical decision making; (2) expand professional, jurisdictional, and personal scope of practice; (3) evolve entry-level education; and (4) stimulate new investigations in nutrition care and pain science research. In doing so, physical therapists can assert their role throughout the pain management continuum, champion innovative research initiatives, and enhance public health by reducing the impact of chronic pain.

IMPACT

The nutrition care process for pain management is defined as the basic duty to provide adequate and appropriate nutrition education and counseling to people living with pain. Including the nutrition care process as part of a multimodal approach to pain management provides an opportunity for physical therapists to assert their role throughout the pain management continuum. This includes championing innovative research initiatives and enhancing public health by reducing the impact of chronic pain for over 50 million Americans.

Conservative management of pediatric temporomandibular disc displacement presenting as juvenile idiopathic arthritis: a case report

There is limited research regarding management of temporomandibular disorders (TMD) in adolescents with imaging signs of juvenile idiopathic arthritis (JIA). An 11-year-old girl presented to a hospital-based chiropractor for evaluation of a 1.5-year history of unilateral temporomandibular joint (TMJ) pain and trismus. Previously, pediatric rheumatologists diagnosed JIA after contrast-enhanced magnetic resonance imaging revealed edema, effusion, and bilateral anterior disc displacement, and recommended methotrexate, corticosteroid injection, and arthrocentesis. The chiropractor questioned the JIA diagnosis, instead relating symptoms to a mechanical TMD/disc origin. Manual therapy, TMJ exercises, and acupuncture improved TMJ pain and opening. Invasive medical JIA interventions were avoided without long-term recurrence, further questioning the preceding JIA diagnosis. The success of this case suggests that stepped care, beginning with conservative treatment, has value for adolescents with TMD suspect for JIA. Integration of chiropractors and acupuncturists into healthcare institutions may facilitate this care model by affording nonpharmacologic interventions earlier in patient care.

The acceptability and feasibility of screening, brief intervention, and referral to treatment for pain management among new England veterans with chronic pain: A pilot study

OBJECTIVES

Musculoskeletal disorders often lead to chronic pain in Veterans. Chronic pain puts sufferers at risk for substance misuse, and early intervention is needed for both conditions. This pilot study tested the feasibility and acceptability of a Screening, Brief Intervention, and Referral to Treatment for Pain Management intervention (SBIRT-PM) to help engage Veterans seeking disability compensation for painful musculoskeletal disorders in multimodal pain treatment and to reduce risky substance use, when indicated.

METHODS

This pilot study enrolled 40 Veterans from 8 medical centers across New England in up to 4 sessions of telephone-based counseling using a motivational interviewing framework. Counseling provided education about, and facilitated engagement in, multimodal pain treatments. Study eligibility required Veterans be engaged in no more than 2 Veteran Affairs (VA) pain treatment modalities, and study participation involved a 12-week postassessment and semistructured interview about the counseling process.

RESULTS

Majorities of enrolled Veterans screened positive for comorbid depression and problematic substance use. Regarding the offered counseling, 80% of participants engaged in at least one session, with a mean of 3 sessions completed. Ninety percent of participants completed the postassessment. Numerically, most measures improved slightly from baseline to week 12. In semistructured interviews, participants described satisfaction with learning about new pain care services, obtaining assistance connecting to services, and receiving support from their counselors.

DISCUSSION

It was feasible to deliver SBIRT-PM to Veterans across New England to promote engagement in multimodal pain treatment and to track study outcomes over 12 weeks. Preliminary results suggest SBIRT-PM was well-received and has promise for the targeted outcomes.

Improvement in pain interference and function by an allied health pain management program: Results of a randomized trial

BACKGROUND

Chronic pain is a significant health problem worldwide and requires a biopsychosocial treatment approach. Access to traditional pain medicine specialist services is limited and innovative treatment models are required to support patients in tertiary care. The study evaluated the clinical effectiveness and safety of the Treatment Access Pathway (TAP), an allied health expanded scope model of care which included innovative group assessment and collaboration with patients to create individualized treatment plans.

METHODS

One hundred and eighty-one patients referred to a tertiary level chronic pain service were randomly allocated to either the TAP or the waitlist study groups. Primary (pain interference) and secondary outcome measures were collected at recruitment and again at 6 months. Per-protocol analyses were utilized due to high participant attrition (46% across groups).

RESULTS

The TAP group reported greater reductions in pain interference at 6 months than waitlist group (0.9, 95% CI: 0.2-1.6), with more than half of the TAP group (52%) reporting clinically significant improvement. In addition, statistically significant differences between the TAP and waitlist groups were observed for objective measurements of walking endurance (5.4 m, 95% CI: 1.7-9.1); and global impressions of change (1.4 unit decrease, 95% CI: 1-1.9). Nil adverse events were recorded.

CONCLUSIONS

The study suggests that an expanded scope allied health model of care prioritizing patient choice and group-based interventions provides modest benefits for tertiary-referral chronic pain patients. TAP warrants further investigation as a potentially viable alternative for tertiary healthcare where traditional pain services are unavailable or have long waiting lists.

SIGNIFICANCE

The study tests effectiveness and safety of an expanded scope allied health-led chronic pain program. Despite a high attrition rate, the study showed reduced pain interference and increased physical function in those who completed the protocol. The results are promising and support introduction of this model as an adjunct to existing traditional chronic pain models of care, with a particular focus on improving participant retention in the program. Additionally, the model of care can be used as a standalone chronic pain model of care where no other pain management resources are available. The study was registered on ANZCTR (Trial ID: ACTRN12617001284358).

Management of chronic musculoskeletal pain in veterans: a systematic review

Background and aim of the work.

Veterans are military with health problems due to military conditions. The improved body armor and operational conditions has reduced the number of deaths, but increased the number of veterans with severe injuries, affected by musculoskeletal pain and associated syndromes, such as post-traumatic stress disorder. Multimodal approaches are considered in USA the gold standard for the treatment of these problems, while in Europe and Italy the data are unknown. The aim of this review was to describe and summarize multimodal therapeutic approaches that apply to the veteran population for chronic musculoskeletal pain and relate syndromes management.

Methods.

A comprehensive systematic review of the literature on Cochrane Library, PubMed, CINAHL e PsycINFO databases was conducted, from 2001 to 2020.

Results.

228 papers have been found, 134 were selected after the first screening. 24 quantitative studies were included in the review, all from USA. Different multimodal interventions with different kind of treatment types emerged. The analyzed studies’ sample size was 11 million (mean age = 57.67 years; SD=±11.94). The multimodal approaches showed a significant improvement in all outcomes (pain reduction and control, opioid therapy reduction, psychosocial outcomes) compared to traditional therapy.

Conclusions.

Multimodal therapeutic approaches seem to guarantee a good management chronic musculoskeletal pain and related mental disorders, and the reduction and control to opioid use. Military nurses emerged as professionals who have a central role in this approach. European and Italian authorities should consider veterans, in order to assess their expected increase in the future.

A cost-utility analysis of multimodal pain rehabilitation in primary healthcare

OBJECTIVES

Multimodal rehabilitation programs (MMRPs) have been shown to be both cost-effective and an effective method for managing chronic pain in specialist care. However, while the vast majority of patients are treated in primary healthcare, MMRPs are rarely practiced in these settings. Limited time and resources for everyday activities alongside the complexity of chronic pain makes the management of chronic pain challenging in primary healthcare and the focus is on unimodal treatment. In order to increase the use of MMRPs incentives such as cost savings and improved health status in the patient group are needed. The aim of this study was to evaluate the cost-effectiveness of MMRPs for patients with chronic pain in primary healthcare in two Swedish regions. The aim of this study was to evaluate the cost-effectiveness of MMRPs at one-year follow-up in comparison with care as usual for patients with chronic pain in primary healthcare in two Swedish regions.

METHODS

A cost-utility analysis was performed alongside a prospective cohort study comparing the MMRP with the alternative of continuing with care as usual. The health-related quality of life (HRQoL), using EQ5D, and working situation of 234 participants were assessed at baseline and one-year follow-up. The primary outcome was cost per quality-adjusted life year (QALY) gained while the secondary outcome was sickness absence. An extrapolation of costs was performed based on previous long-term studies in order to evaluate the effects of the MMRP over a five-year time period.

RESULTS

The mean (SD) EQ5D index, which measures HRQoL, increased significantly (p<0.001) from 0.34 (0.32) to 0.44 (0.32) at one-year follow-up. Sickness absence decreased by 15%. The cost-utility analysis showed a cost per QALY gained of 18 704 € at one-year follow-up.

CONCLUSIONS

The results indicate that the MMRP significantly improves the HRQoL of the participants and is a cost-effective treatment for patients with chronic pain in primary healthcare when a newly suggested cost-effectiveness threshold of 19 734 € is implemented. The extrapolation indicates that considerable cost savings in terms of reduced loss of production and gained QALYs may be generated if the effects of the MMRP are maintained beyond one-year follow-up. The study demonstrates potential benefits of MMRPs in primary healthcare for both the patient with chronic pain and the society as a whole. The cost-effectiveness of MMRPs in primary healthcare has scarcely been studied and further long-term studies are needed in these settings.

Screening, Brief Intervention, and Referral to Treatment for Pain Management for Veterans Seeking Service-Connection Payments for Musculoskeletal Disorders: SBIRT-PM Study Protocol

Background

Veterans with significant chronic pain from musculoskeletal disorders are at risk of substance misuse. Veterans whose condition is the result of military service may be eligible for a disability pension. Department of Veterans Affairs compensation examinations, which determine the degree of disability and whether it was connected to military service, represent an opportunity to engage Veterans in pain management and substance use treatments. A multisite randomized clinical trial is testing the effectiveness and cost-effectiveness of Screening, Brief Intervention, and Referral to Treatment for Pain Management (SBIRT-PM) for Veterans seeking compensation for musculoskeletal disorders. This telephone-based intervention is delivered through a hub-and-spoke configuration.

Design

This study is a two-arm, parallel-group, 36-week, multisite randomized controlled single-blind trial. It will randomize 1,100 Veterans experiencing pain and seeking service-connection for musculoskeletal disorders to either SBIRT-PM or usual care across eight New England VA medical centers. The study balances pragmatic with explanatory methodological features. Primary outcomes are pain severity and number of substances misused. Nonpharmacological pain management and substance use services utilization are tracked in the trial.

Summary

Early trial enrollment targets were met across sites. SBIRT-PM could help Veterans, at the time of their compensation claims, use multimodal pain treatments and reduce existing substance misuse. Strategies to address COVID-19 pandemic impacts on the SBIRT-PM protocol have been developed to maintain its pragmatic and exploratory integrity.

Implementation of the Ottawa Hospital Pain Clinic stepped care program: A preliminary report

BACKGROUND

Access to multidisciplinary pain management treatment in Canada is limited, with wait times up to 4 years. Stepped care approaches to mental health treatment have led to substantial reduction and elimination of wait times and may be applicable to chronic pain settings. There is no unifying framework for stepped care chronic pain programs. A systematic review of the efficacy of stepped care in chronic pain management conducted by the Canadian Agency for Drugs and Technologies reported varied results that may be due to heterogeneous stepped care models across facilities.

AIM

We propose a unifying framework for multidisciplinary stepped care chronic pain programs and present its application at The Ottawa Hospital Pain Clinic. The Ottawa Hospital stepped care framework is an eight-tiered approach that allows patients the opportunity to decide collaboratively with a health care professional which treatment program will best suit their needs for the management of chronic pain. As levels of stepped care increase, the time and resource commitment to each step will also increase. Treatment is stepped up or down, depending on patient needs.

METHOD

This is a descriptive case study.

RESULTS

Implementing the interprofessional model of care with the stepped care program has eliminated wait times for access to The Ottawa Hospital Pain Clinic Interprofessional Chronic Pain Management Program and has improved communication between professions of the interprofessional team, resulting in better care for patients.

CONCLUSION

More research is needed to further develop and evaluate the clinical efficacy of stepped care to manage chronic pain.

Multidisciplinary care for opioid dose reduction in patients with chronic non-cancer pain: A systematic realist review

CONTEXT

Opioid related deaths are at epidemic levels in many developed nations globally. Concerns about the contribution of prescribed opioids, and particularly high-dose opioids, continue to mount as do initiatives to reduce prescribing. Evidence around opioid tapering, which can be challenging and potentially hazardous, is not well developed. A recent national guideline has recognized this and recommended referral to multidisciplinary care for challenging cases of opioid tapering. However, multidisciplinary care for opioid tapering is not well understood or defined.

OBJECTIVE

Identify the existing literature on any multidisciplinary care programs that evaluate impact on opioid use, synthesize how these programs work and clarify whom they benefit.

STUDY DESIGN

Systematic rapid realist review.

DATASET

Bibliographic databases (MEDLINE, EMBASE, CINAHL, PsycINFO, Cochrane Library), grey literature, reference hand search and formal expert consultation.

RESULTS

95 studies were identified. 75% of the programs were from the United States and the majority (n = 62) were published after 2000. A minority (n = 23) of programs reported on >12 month opioid use outcomes. There were three necessary but insufficient mechanisms common to all programs: pain relief, behavior change and active medication management. Programs that did not include a combination of all three mechanisms did not result in opioid dose reductions. A concerning 20-40% of subjects resumed opioid use within one year of program completion.

CONCLUSIONS

Providing alternative analgesia is insufficient for reducing opioid doses. Even high quality primary care multidisciplinary care programs do not reduce prescribed opioid use unless there is active medication management accomplished by changing the primary opioid prescriber. Rates of return to use of opioids from these programs are very concerning in the current context of a highly potent and lethal street drug supply. This contextual factor may be powerful enough to undermine the modest benefits of opioid dose reduction via multidisciplinary care.

Pain Care in the Department of Veterans Affairs: Understanding How a Cultural Shift in Pain Care Impacts Provider Decisions and Collaboration

OBJECTIVE

Over the past decade, the Department of Veterans Affairs (VA) has experienced a sizeable shift in its approach to pain. The VA's 2009 Pain Management Directive introduced the Stepped Care Model, which emphasizes an interdisciplinary approach to pain management involving pain referrals and management from primary to specialty care providers. Additionally, the Opioid Safety Initiative and 2017 VA/Department of Defense (DoD) clinical guidelines on opioid prescribing set a new standard for reducing opioid use in the VA. These shifts in pain care have led to new pain management strategies that rely on multidisciplinary teams and nonpharmacologic pain treatments. The goal of this study was to examine how the cultural transformation of pain care has impacted providers, the degree to which VA providers are aware of pain care services at their facilities, and their perceptions of multidisciplinary care and collaboration across VA disciplines.

METHODS

We conducted semistructured phone interviews with 39 VA clinicians in primary care, mental health, pharmacy, and physical therapy/rehabilitation at eight Veterans Integrated Service Network medical centers in New England.

RESULTS

We identified four major themes concerning interdisciplinary pain management approaches: 1) the culture of VA pain care has changed dramatically, with a greater focus on nonpharmacologic approaches to pain, though many "old school" providers continue to prefer medication options; 2) most facilities in this sample have no clear roadmap about which pain treatment pathway to follow, with many providers unaware of what treatment to recommend when; 3) despite multiple options for pain treatment, VA multidisciplinary teams generally work together to ensure that veterans receive coordinated pain care; and 4) veteran preferences for care may not align with existing pain care pathways.

CONCLUSIONS

The VA has shifted its practices regarding pain management, with a greater emphasis on nonpharmacologic pain options. The proliferation of nonpharmacologic pain management strategies requires stakeholders to know how to choose among alternative treatments.

Fibromyalgia

Fibromyalgia is characterized by chronic, widespread musculoskeletal pain and associated fatigue, sleep disturbances, and other cognitive and somatic symptoms. For many patients, these symptoms persist for years and lead to frequent health care use; for some, fibromyalgia and its symptoms can be debilitating. Although many treatments are available, management remains challenging. This article highlights the clinical features of fibromyalgia, discusses diagnostic criteria and their evolution, and reviews treatment options.

Best Practices in the Management of Nonmedical Opioid Use in Patients with Cancer-Related Pain

INTRODUCTION

Nonmedical opioid use (NMOU) in patients with cancer is a term covering a spectrum of nonprescribed opioid use. The extent to which an individual uses opioids in a nonprescribed manner will influence propensity for adverse effects such as neurotoxicity, substance use disorder, overdose, and death.

OBJECTIVES

The objectives of this study were to (A) evaluate current literature regarding management of NMOU in patients with cancer-related pain; (B) provide best practice recommendations based on evidence; and (C) integrate practices derived from the management of noncancer pain, where clinically appropriate or when the oncology literature is limited.

METHODS

This study is a narrative review.

IMPLICATIONS

Although harm from NMOU was thought to be rare among oncology patients, about one in five patients with cancer is at risk of adverse outcomes including prolonged opioid use, high opioid doses, and increased health care utilization. The management of NMOU can be challenging because pain is a multidimensional experience encompassing physical, psychological, and spiritual domains. An interdisciplinary team approach is most effective, and management strategies may include (A) education of patients and families; (B) harm reduction, including opioid switching, decreasing the overall daily dose, avoiding concurrent sedative use, and using adjuvant medications for their opioid-sparing potential; (C) managing psychological and spiritual distress with an interdisciplinary team and techniques such as brief motivational interviewing; and (D) risk mitigation by pill counts, frequent clinic visits, and accessing statewide prescription drug monitoring plans.

CONCLUSION

Although many of the management strategies for NMOU in patients with cancer-related pain are modeled on those for chronic non-cancer-related pain, there is emerging evidence that education and harm-reduction initiatives specifically for cancer-related pain are effective.

IMPLICATIONS FOR PRACTICE

Nonmedical opioid use (NMOU) in patients with cancer is a term covering a broad spectrum of nonprescribed opioid use. The extent to which an individual uses opioids in a nonprescribed manner will influence propensity for adverse effects such as neurotoxicity, substance use disorder, overdose, and death. This review evaluates the evidence for best practices in oncology and addresses limitations in the literature with supplemental evidence from noncancer chronic pain. Management recommendations for NMOU are provided, based on a combination of literature-based evidence and best clinical practice. Effective management of NMOU in oncology has the potential to improve quality of life, decrease health utilization, and improve survival.

Factors associated with waiting times for persons with rheumatic conditions in multidisciplinary pain treatment facilities

OBJECTIVES

Access to multidisciplinary pain treatment facilities (MPTF) in Canada is limited by long waiting lists. However, little is known about the factors associated with access to MPTF specifically for persons with rheumatic conditions. This study aimed to 1) determine the waiting time for services in publicly funded MPTF for persons with rheumatic conditions in the province of Quebec, Canada, as well as 2) identify the factors associated with waiting time.

METHODS

This study was conducted using the Quebec Pain Registry, a large database of patients who received pain management services in MPTF. Sociodemographic and clinical variables were assessed for potential associations with waiting time. Descriptive, bivariate analyses and multiple linear regression analyses were conducted.

RESULTS

A total of 3,665 patients with rheumatic conditions were identified within the registry. Patients had a mean age of 55±14 years and the majority were women (65.7%). The average waiting time was 241.2±308.9 days (median=126), with 34.2% of the patients waiting longer than 6 months before having a first appointment. Results indicate that longer pain duration, lower household income, pain onset following a motor vehicle accident, having fibromyalgia, being on permanent disability or unemployed and being referred by a family physician (versus specialist) were significantly associated with longer waiting times.

CONCLUSIONS

Many patients with rheumatic conditions (especially fibromyalgia) face long delays before receiving services in Quebec's MPTF. This study identified several factors associated with waiting time and emphasizes the need to improve access to pain management services.

Effectiveness of a collaborative care intervention for managing major depression and chronic musculoskeletal pain in primary care: A cluster-randomised controlled trial

BACKGROUND

Depression and chronic musculoskeletal pain commonly occur as comorbid conditions, which increases their negative effects on health outcomes. The objective of this study was to assess the effectiveness of the DROP (DepRessiOn and Pain) programme designed for the management of major depression and chronic musculoskeletal pain in primary care.

METHODS

A cluster-randomised controlled trial was carried out between June 2015 and December 2017 with 328 patients with major depression and chronic musculoskeletal pain, randomly allocated to either intervention arm or usual care arm. The intervention included care management, optimised management of depression, and a psychoeducational programme. Outcomes were monitored using blinded interviews over a 12-month period.

TRIAL REGISTRATION

NCT02605278 (ClinicalTrials.gov).

RESULTS

After 12 months, 274 patients were evaluated (83.5% participation). The severity of depression (Hopkins Symptom Checklist score) was 0.23 points lower in the intervention arm [1.11 vs. 1.34; CI95% = -0.42 to -0.04]. Intervention arm's response rate to antidepressant treatment was 18.9% higher [39.6% vs. 20.7%; OR = 2.74; CI95% = 1.12-6.67] and its remission rate for depression was 9.0% higher [20.1% vs. 11.1%; OR = 2.13; CI95% = 0.94-4.85] compared to the usual care arm. There were no significant differences between the two arms in terms of pain severity (Brief Pain Inventory severity score) [6.23 vs. 6.66; difference = -0.39; CI95% = -1.13-0.35] or pain response rate [18.7% vs. 18.5%; OR = 1.02; CI95% = 0.46-2.26].

LIMITATIONS

This is a pragmatic study, and poor adherence to the programme by patients and physicians was a main limitation.

CONCLUSION

The programme improves clinical outcomes for depression, although no clinical benefits were seen for pain.

Association Between Facility-Level Utilization of Non-pharmacologic Chronic Pain Treatment and Subsequent Initiation of Long-Term Opioid Therapy

BACKGROUND

Expert guidelines recommend non-pharmacologic treatments and non-opioid medications for chronic pain and recommend against initiating long-term opioid therapy (LTOT).

OBJECTIVE

We examined whether veterans with incident chronic pain receiving care at facilities with greater utilization of non-pharmacologic treatments and non-opioid medications are less likely to initiate LTOT.

DESIGN

Retrospective cohort study PARTICIPANTS: Veterans receiving primary care from a Veterans Health Administration facility with incident chronic pain between 1/1/2010 and 12/31/2015 based on either of 2 criteria: (1) persistent moderate-to-severe patient-reported pain and (2) diagnoses "likely to represent" chronic pain.

MAIN MEASURES

The independent variable was facility-level utilization of pain-related treatment modalities (non-pharmacologic, non-opioid medications, LTOT) in the prior calendar year. The dependent variable was patient-level initiation of LTOT (≥ 90 days within 365 days) in the subsequent year, adjusting for patient characteristics.

KEY RESULTS

Among 1,094,569 veterans with incident chronic pain from 2010 to 2015, there was wide facility-level variation in utilization of 10 pain-related treatment modalities, including initiation of LTOT (median, 16%; range, 5-32%). Veterans receiving care at facilities with greater utilization of non-pharmacologic treatments were less likely to initiate LTOT in the year following incident chronic pain. Conversely, veterans receiving care at facilities with greater non-opioid and opioid medication utilization were more likely to initiate LTOT; this association was strongest for past year facility-level LTOT initiation (adjusted rate ratio, 2.10; 95% confidence interval, 2.06-2.15, top vs. bottom quartile of facility-level LTOT initiation in prior calendar year).

CONCLUSIONS

Facility-level utilization patterns of non-pharmacologic, non-opioid, and opioid treatments for chronic pain are associated with subsequent patient-level initiation of LTOT among veterans with incident chronic pain. Further studies should seek to understand facility-level variation in chronic pain care and to identify facility-level utilization patterns that are associated with improved patient outcomes.
