Implementation of the veterans health administration national pain management strategy

Drugs used for pain management in gastrointestinal surgery and their implications

Pain is the predominant symptom troubling patients. Pain management is one of the most important aspects in the management of surgical patients leading to early recovery from surgical procedures or in patients with chronic diseases or malignancy. Various groups of drugs are used for dealing with this; however, they have their own implications in the form of adverse effects and dependence. In this article, we review the concerns of different pain-relieving medicines used postoperatively in gastrointestinal surgery and for malignant and chronic diseases.

"It Made Me Not Want to See him…": The Role of Patient-Provider Communication in Influencing Rural-Dwelling Women Veterans' Motivation to Seek Health Care for Managing Chronic Pain

Despite being high health care utilizers, many women Veterans perceive their pain condition to be poorly understood by their providers, which can be a strong demotivator for seeking care. We set out to understand the priorities rural-dwelling women Veterans have for using health care for their chronic pain, and interviewed participants about their experiences with (and priorities for seeking) health care for their chronic pain. Self-Determination Theory identifies three sources of motivation (autonomy, competence, relatedness), all of which were represented through two themes that reflect rural women Veterans' rationale for decision-making to obtain health care for chronic pain: role of trust and competing priorities. Women described their priorities for chronic pain management in terms of their competing priorities for work, education, and supporting their family, but most expressed a desire to function in their daily life and relationships. Second, women discussed the role of trust in their provider as a source of motivation, and the role of patient-provider communication skills and gender played in establishing trust. Rural women Veterans often discussed core values that stemmed from facets of their identity (e.g. gender, military training, ethnicity) that also influenced their decision-making. Our findings provide insight for how providers may use Motivational Interviewing and discuss chronic pain treatment options so that rural-dwelling women Veterans feel autonomous, competent, and understood in their decision-making about their chronic pain. We also discuss importance of acknowledging the effects of disenfranchising talk and perpetuating gendered stereotypes related to chronic pain and theoretical implications of this work.

Comparison of Health Outcomes Over Time Among Women 1990-1991 Gulf War Veterans, Women 1990-1991 Gulf Era Veterans, and Women in the U.S. General Population

INTRODUCTION

The aim of this study is to examine health over almost 20 years of follow-up among women Gulf War veterans and women Gulf Era veterans and compare their health to that of women in the U.S. general population.

METHODS

We used data from a health survey of 1,274 women Gulf War veteran and Gulf Era veteran participants of the Gulf War Longitudinal Study who responded to all three waves. Data on the U.S. population of women came from the 1999-2000, 2005-2006, and 2011-2014 National Health and Nutrition Examination Survey (NHANES). Generalized estimating equations (GEEs) were used to compare the report of disease over time in women Gulf War and Gulf Era veterans. Differences in prevalence at the three survey timepoints were calculated between women Gulf War veterans and the NHANES women population, and women Gulf War Era veterans and the NHANES women population.

RESULTS

Women veterans who deployed to the 1990-1991 Gulf War report poorer health than women veterans who served during the same time but did not deploy. Women veterans reported a lower prevalence of hypertension, stroke, and diabetes than women in the NHANES sample. Women veterans also reported a higher prevalence of arthritis, chronic obstructive pulmonary disease, and skin cancer than women in the NHANES sample.

CONCLUSIONS

This study is the first to characterize the health of a population-based cohort of women Gulf War and women Gulf Era veterans over time and compare it with women's health in a civilian NHANES population. This demonstrates the value of epidemiological research on women veterans and the importance of developing longitudinal cohorts across genders.

Partner engagement for planning and development of non-pharmacological care pathways in the AIM-Back trial

BACKGROUND/AIMS

Embedded pragmatic clinical trials are increasingly recommended for non-pharmacological pain care research due to their focus on examining intervention effectiveness within real-world settings. Engagement with patients, health care providers, and other partners is essential, yet there is limited guidance for how to use engagement to meaningfully inform the design of interventions to be tested in pain-related pragmatic clinical trials. This manuscript aims to describe the process and impacts of partner input on the design of two interventions (care pathways) for low back pain currently being tested in an embedded pragmatic trial in the Veterans Affairs health care system.

METHODS

Sequential cohort design for intervention development was followed. Engagement activities were conducted with 25 participants between November 2017 and June 2018. Participants included representatives from multiple groups: clinicians, administrative leadership, patients, and caregivers.

RESULTS

Partner feedback led to several changes in each of the care pathways to improve patient experience and usability. Major changes to the sequenced care pathway included transitioning from telephone-based delivery to a flexible telehealth model, increased specificity about pain modulation activities, and reduction of physical therapy visits. Major changes to the pain navigator pathway included transitioning from a traditional stepped care model to one that offers care in a feedback loop, increased flexibility regarding pain navigator provider type, and increased specificity for patient discharge criteria. Centering patient experience emerged as a key consideration from all partner groups.

CONCLUSION

Diverse input is important to consider before implementing new interventions in embedded pragmatic trials. Partner engagement can increase acceptability of new care pathways to patients and providers and enhance uptake of effective interventions by health systems.

Chronic Pain, Cannabis Legalization and Cannabis Use Disorder in Veterans Health Administration Patients, 2005 to 2019

Background

The risk for cannabis use disorder (CUD) is elevated among U.S. adults with chronic pain, and CUD rates are disproportionately increasing in this group. Little is known about the role of medical cannabis laws (MCL) and recreational cannabis laws (RCL) in these increases. Among U.S. Veterans Health Administration (VHA) patients, we examined whether MCL and RCL effects on CUD prevalence differed between patients with and without chronic pain.

Methods

Patients with ≥1 primary care, emergency, or mental health visit to the VHA and no hospice/palliative care within a given calendar year, 2005-2019 (yearly n=3,234,382 to 4,579,994) were analyzed using VHA electronic health record (EHR) data. To estimate the role of MCL and RCL enactment in the increases in prevalence of diagnosed CUD and whether this differed between patients with and without chronic pain, staggered-adoption difference-in-difference analyses were used, fitting a linear binomial regression model with fixed effects for state, categorical year, time-varying cannabis law status, state-level sociodemographic covariates, a chronic pain indicator, and patient covariates (age group [18-34, 35-64; 65-75], sex, and race and ethnicity). Pain was categorized using an American Pain Society taxonomy of painful medical conditions.

Outcomes

In patients with chronic pain, enacting MCL led to a 0·14% (95% CI=0·12%-0·15%) absolute increase in CUD prevalence, with 8·4% of the total increase in CUD prevalence in MCL-enacting states attributable to MCL. Enacting RCL led to a 0·19% (95%CI: 0·16%, 0·22%) absolute increase in CUD prevalence, with 11·5% of the total increase in CUD prevalence in RCL-enacting states attributable to RCL. In patients without chronic pain, enacting MCL and RCL led to smaller absolute increases in CUD prevalence (MCL: 0·037% [95%CI: 0·03, 0·05]; RCL: 0·042% [95%CI: 0·02, 0·06]), with 5·7% and 6·0% of the increases in CUD prevalence attributable to MCL and RCL. Overall, MCL and RCL effects were significantly greater in patients with than without chronic pain. By age, MCL and RCL effects were negligible in patients age 18-34 with and without pain. In patients age 35-64 with and without pain, MCL and RCL effects were significant (p<0.001) but small. In patients age 65-75 with pain, absolute increases were 0·10% in MCL-only states and 0·22% in MCL/RCL states, with 9·3% of the increase in CUD prevalence in MCL-only states attributable to MCL, and 19.4% of the increase in RCL states attributable to RCL. In patients age 35-64 and 65-75, MCL and RCL effects were significantly greater in patients with pain.

Interpretation

In patients age 35-75, the role of MCL and RCL in the increasing prevalence of CUD was greater in patients with chronic pain than in those without chronic pain, with particularly pronounced effects in patients with chronic pain age 65-75. Although the VHA offers extensive behavioral and non-opioid pharmaceutical treatments for pain, cannabis may seem a more appealing option given media enthusiasm about cannabis, cannabis commercialization activities, and widespread public beliefs about cannabis efficacy. Cannabis does not have the risk/mortality profile of opioids, but CUD is a clinical condition with considerable impairment and comorbidity. Because cannabis legalization in the U.S. is likely to further increase, increasing CUD prevalence among patients with chronic pain following state legalization is a public health concern. The risk of chronic pain increases as individuals age, and the average age of VHA patients and the U.S. general population is increasing. Therefore, clinical monitoring of cannabis use and discussion of the risk of CUD among patients with chronic pain is warranted, especially among older patients.

Research in Context

Evidence before this study: Only three studies have examined the role of state medical cannabis laws (MCL) and/or recreational cannabis laws (RCL) in the increasing prevalence of cannabis use disorder (CUD) in U.S. adults, finding significant MCL and RCL effects but with modest effect sizes. Effects of MCL and RCL may vary across important subgroups of the population, including individuals with chronic pain. PubMed was searched by DH for publications on U.S. time trends in cannabis legalization, cannabis use disorders (CUD) and pain from database inception until March 15, 2023, without language restrictions. The following search terms were used: (medical cannabis laws) AND (pain) AND (cannabis use disorder); (recreational cannabis laws) AND (pain) AND (cannabis use disorder); (cannabis laws) AND (pain) AND (cannabis use disorder). Only one study was found that had CUD as an outcome, and this study used cross-sectional data from a single year, which cannot be used to determine trends over time. Therefore, evidence has been lacking on whether the role of state medical and recreational cannabis legalization in the increasing US adult prevalence of CUD differed by chronic pain status.Added value of this study: To our knowledge, this is the first study to examine whether the effects of state MCL and RCL on the nationally increasing U.S. rates of adult cannabis use disorder differ by whether individuals experience chronic pain or not. Using electronic medical record data from patients in the Veterans Health Administration (VHA) that included extensive information on medical conditions associated with chronic pain, the study showed that the effects of MCL and RCL on the prevalence of CUD were stronger among individuals with chronic pain age 35-64 and 65-75, an effect that was particularly pronounced in older patients ages 65-75.Implications of all the available evidence: MCL and RCL are likely to influence the prevalence of CUD through commercialization that increases availability and portrays cannabis use as 'normal' and safe, thereby decreasing perception of cannabis risk. In patients with pain, the overall U.S. decline in prescribed opioids may also have contributed to MCL and RCL effects, leading to substitution of cannabis use that expanded the pool of individuals vulnerable to CUD. The VHA offers extensive non-opioid pain programs. However, positive media reports on cannabis, positive online "information" that can sometimes be misleading, and increasing popular beliefs that cannabis is a useful prevention and treatment agent may make cannabis seem preferable to the evidence-based treatments that the VHA offers, and also as an easily accessible option among those not connected to a healthcare system, who may face more barriers than VHA patients in accessing non-opioid pain management. When developing cannabis legislation, unintended consequences should be considered, including increased risk of CUD in large vulnerable subgroups of the population.

Self-administered acupressure for veterans with chronic back pain: Study design and methodology of a type 1 hybrid effectiveness implementation randomized controlled trial

BACKGROUND

Chronic low back pain is prevalent and disabling in Veterans, but effective pain management is challenging. Clinical practice guidelines emphasize multimodal pain management including evidence-based complementary and integrative health treatments such as acupressure as a first line of care. Unfortunately, the ability to replicate interventions, cost, resources, and limited access are implementation barriers. Self-administered acupressure has shown positive effects on pain and can be practiced anywhere with little to no side effects.

METHODS/DESIGN

The aims of this Type 1 hybrid effectiveness implementation randomized controlled trial are 1) to determine effectiveness of a self-administered acupressure protocol at improving pain interference and secondary outcomes of fatigue, sleep quality, and disability in 300 Veterans with chronic low back pain, and 2) evaluate implementation barriers and facilitators to scale-up acupressure utilization within Veterans Health Administration (VHA). Participants randomized to the intervention will receive instruction on acupressure application using an app that facilitates daily practice for 6 weeks. During weeks 6 through 10, participants will discontinue acupressure to determine sustainability of effects. Participants randomized to waitlist control will continue their usual care for pain management and receive study materials at the end of the study period. Outcomes will be collected at baseline and at 6- and 10-weeks post baseline. The primary outcome is pain interference, measured by the PROMIS pain interference scale. Using established frameworks and a mixed methods approach, we will evaluate intervention implementation.

DISCUSSION

If acupressure is effective, we will tailor strategies to support implementation in the VHA based on study findings.

Association between early nonpharmacological management and follow-up for low back pain in the veterans health administration

Background

Low back pain (LBP) is a common reason individuals seek healthcare. Nonpharmacologic management (NPM) is often recommended as a primary intervention, and earlier use of NPM for LBP shows positive clinical outcomes. Our purpose was to evaluate how timing of engagement in NPM for LBP affects downstream LBP visits during the first year.

Methods

This study was a secondary analysis of an observational cohort study of national electronic health record data. Patients entering the Musculoskeletal Diagnosis/Complementary and Integrative Health Cohort with LBP from October 1, 2016 to September 30, 2017 were included. Exclusive patient groups were defined by engagement in NPM within 30 days of entry ("very early NPM"), between 31 and 90 days ("early NPM"), or not within the first 90 days ("no NPM"). The outcome was time, in days, to the final LBP follow-up after 90 days and within the first year. Cox proportional hazards regression was used to model time to final follow up, controlling for additional demographic and clinical covariables.

Results

The study population included 44,175 patients, with 16.7% engaging in very early NPM and 13.1% in early NPM. Patients with very early NPM (5.2 visits, SD=4.5) or early NPM (5.7 visits, SD=4.6) had a higher mean number of LBP visits within the first year than those not receiving NPM in the first 90 days (3.2 visits, SD = 2.5). The very early NPM (HR=1.50, 95% CI: 1.46-1.54; median=48 days, IQR=97) and early NPM (HR=1.27, 95% CI: 1.23-1.30; median=88 days, IQR=92) had a significantly shorter time to final follow-up than the no NPM group (median=109 days, IQR=150).

Conclusions

Veterans Health Administration patients receiving NPM for LBP within the first 90 days after initially seeking care demonstrate a significantly faster time to final follow-up visit within the first year compared to those who do not.

Complementary and Integrative Health Approaches and Pain Care Quality in the Veterans Health Administration Primary Care Setting: A Quasi-Experimental Analysis

Background: Complementary and integrative health (CIH) approaches have been recommended in national and international clinical guidelines for chronic pain management. We set out to determine whether exposure to CIH approaches is associated with pain care quality (PCQ) in the Veterans Health Administration (VHA) primary care setting. Methods: We followed a cohort of 62,721 Veterans with newly diagnosed musculoskeletal disorders between October 2016 and September 2017 over 1-year. PCQ scores were derived from primary care progress notes using natural language processing. CIH exposure was defined as documentation of acupuncture, chiropractic or massage therapies by providers. Propensity scores (PSs) were used to match one control for each Veteran with CIH exposure. Generalized estimating equations were used to examine associations between CIH exposure and PCQ scores, accounting for potential selection and confounding bias. Results: CIH was documented for 14,114 (22.5%) Veterans over 16,015 primary care clinic visits during the follow-up period. The CIH exposure group and the 1:1 PS-matched control group achieved superior balance on all measured baseline covariates, with standardized differences ranging from 0.000 to 0.045. CIH exposure was associated with an adjusted rate ratio (aRR) of 1.147 (95% confidence interval [CI]: 1.142, 1.151) on PCQ total score (mean: 8.36). Sensitivity analyses using an alternative PCQ scoring algorithm (aRR: 1.155; 95% CI: 1.150-1.160) and redefining CIH exposure by chiropractic alone (aRR: 1.118; 95% CI: 1.110-1.126) derived consistent results. Discussion: Our data suggest that incorporating CIH approaches may reflect higher overall quality of care for patients with musculoskeletal pain seen in primary care settings, supporting VHA initiatives and the Declaration of Astana to build comprehensive, sustainable primary care capacity for pain management. Future investigation is warranted to better understand whether and to what degree the observed association may reflect the therapeutic benefits patients actually received or other factors such as empowering provider-patient education and communication about these approaches.

Luther S, Heapy A, Brandt C, J. Lisi A. Extracting Pain Care Quality Indicators from U.S. Veterans Health Administration Chiropractic Care Using Natural Language Processing

BACKGROUND

Musculoskeletal pain is common in the Veterans Health Administration (VHA), and there is growing national use of chiropractic services within the VHA. Rapid expansion requires scalable and autonomous solutions, such as natural language processing (NLP), to monitor care quality. Previous work has defined indicators of pain care quality that represent essential elements of guideline-concordant, comprehensive pain assessment, treatment planning, and reassessment.

OBJECTIVE

Our purpose was to identify pain care quality indicators and assess patterns across different clinic visit types using NLP on VHA chiropractic clinic documentation.

METHODS

Notes from ambulatory or in-hospital chiropractic care visits from October 1, 2018 to September 30, 2019 for patients in the Women Veterans Cohort Study were included in the corpus, with visits identified as consultation visits and/or evaluation and management (E&M) visits. Descriptive statistics of pain care quality indicator classes were calculated and compared across visit types.

RESULTS

There were 11,752 patients who received any chiropractic care during FY2019, with 63,812 notes included in the corpus. Consultation notes had more than twice the total number of annotations per note (87.9) as follow-up visit notes (34.7). The mean number of total classes documented per note across the entire corpus was 9.4 (standard deviation [SD]  =  1.5). More total indicator classes were documented during consultation visits with (mean  =  14.8, SD  =  0.9) or without E&M (mean  =  13.9, SD  =  1.2) compared to follow-up visits with (mean  =  9.1, SD  =  1.4) or without E&M (mean  =  8.6, SD  =  1.5). Co-occurrence of pain care quality indicators describing pain assessment was high.

CONCLUSION

VHA chiropractors frequently document pain care quality indicators, identifiable using NLP, with variability across different visit types.

Pre-implementation formative evaluation of cooperative pain education and self-management expanding treatment for real-world access: A pragmatic pain trial

OBJECTIVE

Cognitive behavioral therapy for chronic pain (CBT-CP) is an evidence-based treatment for improving functioning and pain intensity for people with chronic pain with extensive evidence of effectiveness. However, there has been relatively little investigation of the factors associated with successful implementation and uptake of CBT-CP, particularly clinician and system level factors. This formative evaluation examined barriers and facilitators to the successful implementation and uptake of CBT-CP from the perspective of CBT-CP clinicians and referring primary care clinicians.

METHODS

Qualitative interviews guided by the Consolidated Framework for Implementation Research were conducted at nine geographically diverse Veterans Affairs sites as part of a pragmatic clinical trial comparing synchronous, clinician-delivered CBT-CP and remotely delivered, technology-assisted CBT-CP. Analysis was informed by a grounded theory approach.

RESULTS

Twenty-six clinicians (CBT-CP clinicians = 17, primary care clinicians = 9) from nine VA medical centers participated in individual qualitative interviews conducted by telephone from April 2019 to August 2020. Four themes emerged in the qualitative interviews: (1) the complexity and variability of referral pathways across sites, (2) referring clinician's lack of knowledge about CBT-CP, (3) referring clinician's difficulty identifying suitable candidates for CBT-CP, and (4) preference for interventions that can be completed from home.

CONCLUSIONS

This formative evaluation identified clinician and system barriers to widespread implementation of CBT-CP and allowed for refinement of the subsequent implementation of two forms of CBT-CP in an ongoing pragmatic trial. Identification of relative difference in barriers and facilitators in the two forms of CBT-CP may emerge more clearly in a pragmatic trial that evaluates how treatments perform in real-world settings and may provide important information to guide future system-wide implementation efforts.

Barriers and facilitators of evidence-based psychotherapies for chronic pain in adults: A systematic review

Cognitive behavioral therapy (CBT), acceptance and commitment therapy (ACT), and mindfulness-based stress reduction (MBSR) have demonstrated effectiveness for improving outcomes in chronic pain. These evidence-based psychotherapies (EBPs) remain underutilized in clinical practice, however. To identify research gaps and next steps for improving uptake of EBPs, we conducted a systematic review of patient-, provider-, and system-level barriers and facilitators of their use for chronic pain. We searched MEDLINE, Embase, PsycINFO, and CINAHL databases databases from inception through September 2022. Prespecified eligibility criteria included outpatient treatment of adults with chronic pain; examination of barriers and facilitators and/or evaluation of implementation strategies; conducted in the United States (US), United Kingdom (UK), Ireland, Canada or Australia; and publication in English. Two reviewers independently assessed eligibility and rated quality. We conducted a qualitative synthesis of results using a best-fit framework approach building upon domains of the Consolidated Framework for Implementation Research (CFIR). We identified 34 eligible studies (33 moderate or high quality), most (n=28) of which addressed patient-level factors. Shared barriers across EBPs included variable patient buy-in to therapy rationale and competing responsibilities for patients; shared facilitators included positive group or patient-therapist dynamics. Most studies examining ACT and all examining MBSR assessed only group formats. No studies compared barriers, facilitators, or implementation strategies of group CBT to individual CBT, or of telehealth to in-person EBPs. Conceptual mismatches of patient knowledge and beliefs with therapy principles were largely analyzed qualitatively, and studies did not explore how these mismatches were addressed to support engagement. Future research on EBPs for chronic pain in real-world practice settings is needed to explore provider and system-level barriers and facilitators, heterogeneity of effects and uptake, and both effects and uptake of EBPs delivered in various formats, including group vs. individual therapy and telehealth or asynchronous digital approaches. Perspective This systematic review synthesizes evidence on barriers and facilitators to uptake of cognitive behavioral therapy, acceptance and commitment therapy, and mindfulness-based stress reduction for chronic pain. Findings can guide future implementation work to increase availability and use of evidence-based psychotherapies for treatment of chronic pain. Registration: PROSPERO number CRD42021252038.

Sequential and Comparative Evaluation of Pain Treatment Effectiveness Response (SCEPTER), a pragmatic trial for conservative chronic low back pain treatment

BACKGROUND

Chronic low back pain (cLBP) is a common and highly disabling problem world-wide. Although many treatment options exist, it is unclear how to best sequence the multitude of care options to provide the greatest benefit to patients.

METHODS

The Sequential and Comparative Evaluation of Pain Treatment Effectiveness Response (SCEPTER) trial uses a pragmatic, randomized, stepped design. Enrollment targets 2529 participants from 20 Veterans Affairs (VA) medical centers. Participants with chronic low back pain will first be randomized to one of three options: 1) an internet-based self-management program (Pain EASE); 2) a tailored physical therapy program (Enhanced PT); or 3) continued care with active monitoring (CCAM), a form of usual care. Participants not achieving a 30% or 2-point reduction on the study's primary outcome (Brief Pain Inventory Pain Interference (BPI-PI) subscale), 3 months after beginning treatment may undergo re-randomization in a second step to cognitive behavioral therapy for chronic pain, spinal manipulation therapy, or yoga. Secondary outcomes include pain intensity, back pain-related disability, depression, and others. Participants will be assessed every three months until 12 months after initiating their final trial therapy. Companion economic and implementation analyses are also planned.

RESULTS

The SCEPTER trial is currently recruiting and enrolling participants.

CONCLUSIONS

Trial results will inform treatment decisions for the stepped management of chronic low back pain - a common and disabling condition. Additional analyses will help tailor treatment selection to individual patient characteristics, promote efficient resource use, and identify implementation barriers of interventions.

Pharmacological and Non-Pharmacological Methods of Postoperative Pain Control Following Oral and Maxillofacial Surgery: A Systematic Review

Background

We aimed to investigate the pharmacological and non-pharmacological interventions used for mitigating pain.

Methods

We integrated randomized controlled trials (RCTs) chosen from PubMed, Google scholar, and Scopus and aimed at assessing the effectiveness of one or multiple variants of Non-steroidal anti-inflammatory drugs (NSAIDs), as well as Narcotic analgesics, compared to corticosteroids, curcumin, hyaluronic acid, and antibiotics. In addition, trials utilizing NSAIDs, including Rofecoxib, which have been withdrawn from market circulation, were deemed ineligible for inclusion.

Result

A total of 9 RCTs were evaluated in this study, and the patients' postoperative pain was assessed using the visual analog scale (VAS) and the time measurement. Moreover, there were various approaches to alleviating pain and discomfort.

Conclusion

The administration of ibuprofen prior to surgery leads to a marked reduction in pain. Pharmacological interventions, such as the administration of dexamethasone and oxycodone, alongside non-pharmacological interventions, such as laser therapy, have been shown to effectively alleviate the discomfort resulting from surgical procedures on the jaw and face.

Contemporary management of pain in cirrhosis: Toward precision therapy for pain

Chronic pain is highly prevalent in patients with cirrhosis and is associated with poor health-related quality of life and poor functional status. However, there is limited guidance on appropriate pain management in this population, and pharmacologic treatment can be harmful, leading to adverse outcomes, such as gastrointestinal bleeding, renal injury, falls, and hepatic encephalopathy. Chronic pain can be categorized mechanistically into three pain types: nociceptive, neuropathic, and nociplastic, each responsive to different therapies. By discussing the identification, etiology, and treatment of these three mechanistic pain descriptors with a focus on specific challenges in patients with cirrhosis, we provide a framework for better tailoring treatments, including nonpharmacologic therapies, to patients' needs.

BeatPain Utah: study protocol for a pragmatic randomised trial examining telehealth strategies to provide non-pharmacologic pain care for persons with chronic low back pain receiving care in federally qualified health centers

INTRODUCTION

Although evidence-based guidelines recommend non-pharmacologic treatments as first-line care for chronic low back pain (LBP), uptake has been limited, particularly in rural, low-income and ethnically diverse communities. The BeatPain study will evaluate the implementation and compare the effectiveness of two strategies to provide non-pharmacologic treatment for chronic LBP. The study will use telehealth to overcome access barriers for persons receiving care in federally qualified health centres (FQHCs) in the state of Utah.

METHODS AND ANALYSIS

BeatPain Utah is a pragmatic randomised clinical trial with a hybrid type I design investigating different strategies to provide non-pharmacologic care for adults with chronic LBP seen in Utah FQHCs. The intervention strategies include a brief pain consult (BPC) and telehealth physical therapy (PT) component provided using either an adaptive or sequenced delivery strategy across two 12-week treatment phases. Interventions are provided via telehealth by centrally located physical therapists. The sequenced delivery strategy provides the BPC, followed by telehealth PT in the first 12 weeks for all patients. The adaptive strategy uses a stepped care approach and provides the BPC in the first 12 weeks and telehealth PT to patients who are non-responders to the BPC component. We will recruit 500 English-speaking or Spanish-speaking participants who will be individually randomised with 1:1 allocation. The primary outcome is the Pain, Enjoyment and General Activity measure of pain impact with secondary outcomes including the additional pain assessment domains specified by the National Institutes (NIH) of Health Helping to End Addiction Long Initiative and implementation measures. Analyses of primary and secondary measures of effectiveness will be performed under longitudinal mixed effect models across assessments at baseline, and at 12, 26 and 52 weeks follow-ups.

ETHICS AND DISSEMINATION

Ethics approval for the study was obtained from the University of Utah Institutional Review Board. On completion, study data will be made available in compliance with NIH data sharing policies.

Non-pharmacological Treatment for Chronic Pain in US Veterans Treated Within the Veterans Health Administration: Implications for Expansion in US Healthcare Systems

BACKGROUND

Consensus guidelines recommend multimodal chronic pain treatment with increased use of non-pharmacological treatment modalities (NPM), including as first-line therapies. However, with many barriers to NPM uptake in US healthcare systems, NPM use may vary across medical care settings. Military veterans are disproportionately affected by chronic pain. Many veterans receive treatment through the Veterans Health Administration (VHA), an integrated healthcare system in which specific policies promote NPM use.

OBJECTIVE

To examine whether veterans with chronic pain who utilize VHA healthcare were more likely to use NPM than veterans who do not utilize VHA healthcare.

DESIGN

Cross-sectional nationally representative study.

PARTICIPANTS

US military veterans (N = 2,836).

MAIN MEASURES

In the 2019 National Health Interview Survey, veterans were assessed for VHA treatment, chronic pain (i.e., past 3-month daily or almost daily pain), symptoms of depression and anxiety, substance use, and NPM (i.e., physical therapy, chiropractic/spinal manipulation, massage, psychotherapy, educational class/workshop, peer support groups, or yoga/tai chi).

KEY RESULTS

Chronic pain (45.2% vs. 26.8%) and NPM use (49.8% vs. 39.4%) were more prevalent among VHA patients than non-VHA veterans. After adjusting for sociodemographic characteristics, psychiatric symptoms, physical health indicators, and use of cigarettes or prescription opioids, VHA patients were more likely than non-VHA veterans to use any NPM (adjusted odds ratio [aOR] = 1.52, 95% CI: 1.07-2.16) and multimodal NPM (aOR = 1.80, 95% CI: 1.12-2.87) than no NPM. Among veterans with chronic pain, VHA patients were more likely to use chiropractic care (aOR = 1.90, 95% CI = 1.12-3.22), educational class/workshop (aOR = 3.02, 95% CI = 1.35-6.73), or psychotherapy (aOR = 4.28, 95% CI = 1.69-10.87).

CONCLUSIONS

Among veterans with chronic pain, past-year VHA use was associated with greater likelihood of receiving NPM. These findings may suggest that the VHA is an important resource and possible facilitator of NPM. VHA policies may offer guidance for expanding use of NPM in other integrated US healthcare systems.

A Comprehensive Assessment of The Eight Vital Signs

The term “vital sign” has been assigned to various phenomena with the presumptive intent to emphasize their importance in health care resulting in the emergence of eight vital signs with multiple designations and overlapping terms. This review developed a case definition for vital signs and identified and described the fifth through eighth vital signs. PubMed/Medline, Google and biographical databases were searched using the individual Medical Subject Headings (MeSH) terms, vital sign and fifth, vital sign and sixth, vital sign and seventh, and vital sign eighth. The search was limited to human clinical studies written in English literature from 1957 up until November 30, 2021. Excluded were articles containing the term vital sign if used alone without the qualifier fifth, sixth, seventh, or eighth or about temperature, blood pressure, pulse, and respiratory rate. One hundred ninety-six articles (122 for the fifth vital sign, 71 for the sixth vital sign, two for the seventh vital sign, and one for the eighth vital sign) constituted the final dataset. The vital signs consisted of 35 terms, classified into 17 categories compromising 186 unique papers for each primary authored article with redundant numbered vital signs for glucose, weight, body mass index, and medication compliance. Eleven terms have been named the fifth vital sign, 25 the sixth vital sign, three the seventh, and one as the eighth vital sign. There are four time-honored vital signs based on the case definition, and they represent an objective bedside measurement obtained noninvasively that is essential for life. Based on this case definition, pulse oximetry qualifies as the fifth while end-tidal CO2 and cardiac output as the sixth. Thus, these terms have been misappropriated 31 times. Although important to emphasize in patient care, the remainder are not vital signs and should not be construed in this manner.

Measuring pain care quality in the Veterans Health Administration primary care setting

ABSTRACT

The lack of a reliable approach to assess quality of pain care hinders quality improvement initiatives. Rule-based natural language processing algorithms were used to extract pain care quality (PCQ) indicators from documents of Veterans Health Administration primary care providers for veterans diagnosed within the past year with musculoskeletal disorders with moderate-to-severe pain intensity across 2 time periods 2013 to 2014 (fiscal year [FY] 2013) and 2017 to 2018 (FY 2017). Patterns of documentation of PCQ indicators for 64,444 veterans and 124,408 unique visits (FY 2013) and 63,427 veterans and 146,507 visits (FY 2017) are described. The most commonly documented PCQ indicators in each cohort were presence of pain, etiology or source, and site of pain (greater than 90% of progress notes), while least commonly documented were sensation, what makes pain better or worse, and pain's impact on function (documented in fewer than 50%). A PCQ indicator score (maximum = 12) was calculated for each visit in FY 2013 (mean = 7.8, SD = 1.9) and FY 2017 (mean = 8.3, SD = 2.3) by adding one point for every indicator documented. Standardized Cronbach alpha for total PCQ scores was 0.74 in the most recent data (FY 2017). The mean PCQ indicator scores across patient characteristics and types of healthcare facilities were highly stable. Estimates of the frequency of documentation of PCQ indicators have face validity and encourage further evaluation of the reliability, validity, and utility of the measure. A reliable measure of PCQ fills an important scientific knowledge and practice gap.

Chronic Pain and Opioid Prescribing: Three Ways for Navigating Complexity at the Clinical‒Population Health Interface

Clinically focused interventions for people living with pain, such as health professional education, clinical decision support systems, prescription drug monitoring programs, and multidisciplinary care to support opioid tapering, have all been promoted as important solutions to the North American opioid crisis. Yet none have so far delivered substantive beneficial opioid-related population health outcomes. In fact, while total opioid prescribing has leveled off or reduced in many jurisdictions, population-level harms from opioids have continued to increase dramatically. We attribute this failure partly to a poor recognition of the epistemic and ethical complexities at the interface of clinical and population health. We draw on a framework of knowledge networks in wicked problems to identify 3 strategies to help navigate these complexities: (1) designing and evaluating clinically focused interventions as complex interventions, (2) reformulating evidence to make population health dynamics apparent, and (3) appealing to the inseparability of facts and values to support decision-making in uncertainty. We advocate that applying these strategies will better equip clinically focused interventions as complements to structural and public health interventions to achieve the desired beneficial population health effects.

Cognitive behavioral therapy for chronic pain in veterans: Evidence for clinical effectiveness in a model program

The U.S. Department of Veterans Affairs (VA) has been training clinicians in its cognitive behavioral therapy for chronic pain (CBT-CP) structured protocol since 2012. The aim of this project was to review patient outcomes to determine the effectiveness of the VA's CBT-CP treatment. From 2012-2018, 1,331 Veterans initiated individual CBT-CP treatment as part of the training program. Patient outcomes were assessed with measures of patient-reported pain intensity, pain catastrophizing, depression, pain interference, and quality of life (physical, psychological, social, and environmental). Mixed models of the effects of time indicated significant changes across pretreatment, midtreatment, and treatment conclusion on all outcomes. There was a large effect size (Cohen's d = 0.78) for pain catastrophizing, and there were medium to large effect sizes (d > 0.60) for worst pain intensity, pain interference, depression, and physical quality of life. Systematic training of therapists and implementation of the VA's CBT-CP protocol yielded significant patient improvements across multiple domains. This offers strong support for the VA's CBT-CP as an effective, safe treatment for Veterans with chronic pain and highlights it as a model to increase the availability of training in standardized, pain-focused, evidence-based, behavioral interventions. The findings suggest that the broad dissemination of such training, including in routine, nonpain specialty settings, would improve patient access to effective, nonpharmacological treatment options in both the public and private sectors.

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.

Association Between Pain Intensity and Discontinuing Opioid Therapy or Transitioning to Intermittent Opioid Therapy After Initial Long-Term Opioid Therapy: A Retrospective Cohort Study

The purpose of this study was to evaluate changes in pain intensity among Veterans transitioning from long-term opioid therapy (LTOT) to either intermittent therapy or discontinuation compared to continued LTOT. Pain intensity was assessed using the Numeric Rating Scale in 90-day increments starting in the 90-day period prior to potential opioid transitions and the two ensuing 90-day periods after transition. Primary analyses used a 1:1 greedy propensity matched sample. A total of 29,293 Veterans switching to intermittent opioids and 5,972 discontinuing opioids were matched to Veterans continuing LTOT. Covariates were well balanced after matching except minor differences in baseline mean pain scores. Pain scores were lower in the follow up periods for those switching to intermittent opioids and discontinuing opioids compared to those continuing LTOT (0-90 days: Intermittent: 3.79, 95%CI: 3.76, 3.82; LTOT: 4.09, 95%CI: 4.06, 4.12, P < .0001; Discontinuation: 3.06, 95%CI: 2.99, 3.13; LTOT: 3.86, 95%CI: 3.79, 3.94, P = <.0001; 91-180 days: Intermittent: 3.76, 95%CI: 3.73, 3.79; LTOT: 3.99, 95%CI: 3.96, 4.02, P < .0001; Discontinuation: 3.01, 95%CI: 2.94, 3.09; LTOT: 3.80, 95%CI: 3.73, 3.87, P = <.0001). Sensitivity analyses found similar results. Discontinuing opioid therapy or switching to intermittent opioid therapy was not associated with increased pain intensity. PERSPECTIVE: This article evaluates the association of switching to intermittent opioid therapy or discontinuing opioids with pain intensity after using opioids long-term. Pain intensity decreased after switching to intermittent therapy or discontinuing opioids, but remained relatively stable for those continuing long-term opioid therapy. Switching to intermittent opioids or discontinuing opioids was not associated with increased pain intensity.

Opioid use as a predictor of pain outcomes in Iraq and Afghanistan Veterans with chronic pain: Analysis of a randomized controlled trial

OBJECTIVE

Our objectives were to: 1) assess the relationship between self-reported opioid use and baseline demographics, clinical characteristics and pain outcomes; and 2) examine whether baseline opioid use moderated the intervention effect on outcomes at 9 months.

DESIGN

We conducted a secondary analysis of data from the Evaluation of Stepped Care for Chronic Pain (ESCAPE) trial, which found stepped-care to be effective for chronic pain in military veterans.

SETTING

A post-deployment clinic and 5 general medicine clinics at a Veteran Affairs Medical Center.

SUBJECTS

241 veterans with chronic musculoskeletal pain; 220 with complete data at 9 months.

METHODS

Examination of baseline relationships and multivariable linear regression to examine baseline opioid use as a moderator of pain-related outcomes including Roland Morris Disability Questionnaire (RMDQ), Brief Pain Inventory (BPI) Interference scale, and Graded Chronic Pain Scale (GCPS) at 9 months.

RESULTS

Veterans reporting baseline opioid use (n = 80) had significantly worse RMDQ (16.0 ± 4.9 vs. 13.4 ± 4.2, P < 0.0001), GCPS (68.7 ± 12.0 vs. 65.0 ± 14.4, p = 0.049), BPI Interference (6.2 ± 2.2 vs. 5.0 ± 2.1, P < 0.0001), and depression (PHQ-9 12.5 ± 6.2 vs. 10.6 ± 5.7, p = 0.016) compared to veterans not reporting baseline opioid use. Using multivariable modeling we found that baseline opioid use moderated the intervention effect on pain-related disability (RMDQ) at 9 months (interaction Beta = -3.88, p = 0.0064), but not pain intensity or interference.

CONCLUSIONS

In a stepped-care trial for pain, patients reporting baseline opioid use had greater improvement in pain disability at 9 months compared to patients not reporting opioid use.

Telehealth and rural-urban differences in receipt of pain care in the Veterans Health Administration

OBJECTIVE

Examine changes in specialty pain utilization in the Veterans Health Administration (VHA) after establishing a virtual interdisciplinary pain team (TelePain).

DESIGN

Retrospective cohort study.

SETTING

A single VHA healthcare system, 2015-2019.

SUBJECTS

33,169 patients with chronic pain-related diagnoses.

METHODS

We measured specialty pain utilization (in-person and telehealth) among patients with moderate to severe chronic pain. We used generalized estimating equations to test the association of time (pre- or post-TelePain) and rurality on receipt of specialty pain care.

RESULTS

Among patients with moderate to severe chronic pain, the reach of specialty pain care increased from 11.1% to 16.2% in the pre- to post-TelePain periods (aOR: 1.37, 95% CI: 1.26-1.49). This was true of both urban patients (aOR: 1.62, 95% CI: 1.53-1.71) and rural patients (aOR: 1.16, 95% CI: 0.99-1.36), although the difference for rural patients was not statistically significant. Among rural patients who received specialty pain care, a high percentage of the visits were delivered by telehealth (nearly 12% in the post-TelePain period), much higher than among urban patients (3%).

CONCLUSIONS

We observed increased use of specialty pain services among all patients with chronic pain. Although rural patients did not achieve the same degree of access and utilization overall as urban patients, their use of pain telehealth increased substantially and may have substituted for in-person visits. Targeted implementation efforts may be needed to further increase the reach of services to patients living in areas with limited specialty pain care options.

Cluster analysis of Canadian Armed Forces veterans living with chronic pain: Life After Service Studies 2016

Objective: This study explored the heterogeneity of Canadian Armed Forces veterans living with chronic pain to inform service needs planning and research using cluster analysis. Design: We used a national cross-sectional Statistics Canada population survey. Participants: Participants included 2754 Canadian Armed Forces (CAF) Regular Force veterans released from service between 1998 and 2015 and surveyed in 2016. Methods: We used cluster analysis of veterans with chronic pain based on pain severity, mental health, and activity limitation characteristics. We compared clusters for sociodemographic, health, and service utilization characteristics. Results: Of 2754 veterans, 1126 (41%) reported chronic pain. Veterans in cluster I (47%) rarely had severe pain (2%) or severe mental health problems (8%), and none had severe activity limitations. Veterans in cluster II (26%) more often than veterans in cluster I but less often than veterans in cluster III endorsed severe pain (27%) and severe mental health problems (22%) and were most likely to report severe activity limitation (91%). Veterans in cluster III (27%) were most likely to report severe pain (36%) and severe mental health problems (96%), and a majority reported severe activity limitations (72%). There was evidence of considerable heterogeneity among individuals in terms of socioeconomic characteristics, pain characteristics, mental and physical health status, activity limitations, social integration, and service utilization indicators. Conclusions: About half of Canadian veterans living with chronic pain infrequently endorse severe pain or serious mental health issues without severe activity limitations. The other half had more complex characteristics. The heterogeneity of CAF veterans with chronic pain emphasizes the need for support systems that can address variability of needs.

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.

Experiences and Knowledge of US Department of Veterans Affairs Clinical Services, Research, and Education: Results From a National Survey of Veterans

OBJECTIVE

This study examined (1) sociodemographic, health, and psychosocial characteristics associated with using the Department of Veterans Affairs (VA) health care system as a primary health care provider; (2) veterans' experience and knowledge of VA clinical services, research, and education; and (3) veteran characteristics associated with VA experience and knowledge.

DESIGN

A nationally representative survey was conducted in 2018; eligibility criteria for participation were adults aged 18 years or older, currently living in the United States, and having served on active duty in the US military.

SETTING

The survey was conducted online using large national survey panels.

PARTICIPANTS

A sample of 1002 veterans across 49 states participated.

MAIN OUTCOME MEASURES

The survey assessed experience and knowledge of majority of VA clinical services, research, and education.

RESULTS

One-quarter of the total sample reported that the VA was their primary health care provider. Among veterans who had ever used VA health care, the majority (68%) reported overall high satisfaction with VA health care but also agreed with "privatizing parts of the VA" (70%). The majority (51%-73%) of veterans reported knowledge of major VA clinical services, with the exception of comprehensive management for chronic pain (24%) and treatment of opioid use disorders (31%). One-quarter to one-half also reported knowledge of several VA research and education centers. Less than 10% of veterans reported having ever used a VA mobile app.

CONCLUSIONS

The US veterans generally reported positive experiences and good knowledge of VA services and resources. Greater awareness of available VA services for chronic pain and opioid use disorders, as well as VA mobile apps, may help promote more comprehensive care in this population.

Adherence to Stepped Care for Management of Musculoskeletal Knee Pain Leads to Lower Health Care Utilization, Costs, and Recurrence

OBJECTIVES

This study aimed to report compliance with stepped care management of patellofemoral pain and determine whether adherence to stepped care results in decreased recurrence and lower health care utilization.

METHODS

A total of 60,730 participants were included, using data from the Military Health System Data Repository, a large single-payer government health system. Outcomes included total knee-related care visits and costs, knee surgeries, opioid prescriptions, and 2-year recurrence. Stepped care was based on interventions delivered within the appropriate timing and in the appropriate order (low risk/cost before high risk/cost).

RESULTS

A total of 54,460 (89.7%) participants received adherent Step 1 care, 10,964 (18.1%) received step 2, and 4168 (6.9%) received step 3. A total of 32.0% and 50.8%, respectively, of all patients in Step 2 and Step 3 care were adherent. Of the 2385 participants (3.9% of cohort) that received both Step 2 and Step 3 care, 24.8% of participants received adherent care. For participants receiving both Step 2 and Step 3 care, adherence resulted in cost savings (mean difference [MD] $1708; 95% confidence interval [CI]: $1241, 2175), fewer knee-related visits (MD 3.4; 95% CI 2.2, 4.7), fewer episodes of knee pain (MD 0.7; 95% CI 0.5, 0.8), fewer knee surgeries (adjusted odds ratio 0.4; 95% CI 0.3, 0.5), and fewer opioid prescriptions (adjusted odds ratio 0.6; 95% CI 0.5, 0.8).

CONCLUSION

These findings demonstrate the value of following stepped care guidelines for pain management in patients with patellofemoral pain.

Pain, Complex Chronic Conditions and Potential Inappropriate Medication in People with Dementia. Lessons Learnt for Pain Treatment Plans Utilizing Data from the Veteran Health Administration

Alzheimer's disease and related dementias (ADRD), pain and chronic complex conditions (CCC) often co-occur leading to polypharmacy and with potential inappropriate medications (PIMs) use, are important risk factors for adverse drug reactions and hospitalizations in older adults. Many US veterans are at high risk for persistent pain due to age, injury or medical illness. Concerns about inadequate treatment of pain-accompanied by evidence about the analgesic efficacy of opioids-has led to an increase in the use of opioid medications to treat chronic pain in the Veterans Health Administration (VHA) and other healthcare systems. This study aims to investigate the relationship between receipt of pain medications and centrally (CNS) acting PIMs among veterans diagnosed with dementia, pain intensity, and CCC 90-days prior to hospitalization. The final analytic sample included 96,224 (81.7%) eligible older veterans from outpatient visits between October 2012-30 September 2013. We hypothesized that veterans with ADRD, and severe pain intensity may receive inappropriate pain management and CNS-acting PIMs. Seventy percent of the veterans, and especially people with ADRD, reported severe pain intensity. One in three veterans with ADRD and severe pain intensity have an increased likelihood for CNS-acting PIMs, and/or opioids. Regular assessment and re-assessment of pain among older persons with CCC, patient-centered tapering or discontinuation of opioids, alternatives to CNS-acting PIMs, and use of non-pharmacological approaches should be considered.

A Sequential Multiple-Assignment Randomized Trial (SMART) for Stepped Care Management of Low Back Pain in the Military Health System: A Trial Protocol

BACKGROUND

The Defense Health Agency has prioritized system-level pain management initiatives within the Military Health System (MHS), with low back pain as one of the key focus areas. A stepped care model focused on nonpharmacologic treatment to promote self-management is recommended. Implementation of stepped care is complicated by lack of information on the most effective nonpharmacologic strategies and how to sequence and tailor the various available options. The Sequential Multiple-Assignment Randomization Trial for Low Back Pain (SMART LBP) is a multisite pragmatic trial using a SMART design to assess the effectiveness of nonpharmacologic treatments for chronic low back pain.

DESIGN

This SMART trial has two treatment phases. Participants from three military treatment facilities are randomized to 6 weeks of phase I treatment, receiving either physical therapy (PT) or Army Medicine's holistic Move2Health (M2H) program in a package specific to low back pain. Nonresponders to treatment in phase I are again randomized to phase II treatment of combined M2H + PT or mindfulness-based treatment using the Mindfulness-Oriented Recovery Enhancement (MORE) program. The primary outcome is the Patient-Reported Outcomes Measurement Information System pain interference computer-adapted test score.

SUMMARY

This trial is part of an initiative funded by the National Institutes of Health, Veterans Affairs, and the Department of Defense to establish a national infrastructure for effective system-level management of chronic pain with a focus on nonpharmacologic treatments. The results of this study will provide important information on nonpharmacologic care for chronic LBP in the MHS embedded within a stepped care framework.

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.

Improving Veteran Access to Integrated Management of Back Pain (AIM-Back): Protocol for an Embedded Pragmatic Cluster-Randomized Trial

BACKGROUND

Coordinated efforts between the National Institutes of Health, the Department of Defense, and the Department of Veterans Affairs have built the capacity for large-scale clinical research investigating the effectiveness of nonpharmacologic pain treatments. This is an encouraging development; however, what constitutes best practice for nonpharmacologic management of low back pain (LBP) is largely unknown.

DESIGN

The Improving Veteran Access to Integrated Management of Back Pain (AIM-Back) trial is an embedded pragmatic cluster-randomized trial that will examine the effectiveness of two different care pathways for LBP. Sixteen primary care clinics will be randomized 1:1 to receive training in delivery of 1) an integrated sequenced-care pathway or 2) a coordinated pain navigator pathway. Primary outcomes are pain interference and physical function (Patient-Reported Outcomes Measurement Information System Short Form [PROMIS-SF]) collected in the electronic health record at 3 months (n=1,680). A subset of veteran participants (n=848) have consented to complete additional surveys at baseline and at 3, 6, and 12 months for supplementary pain and other measures.

SUMMARY

AIM-Back care pathways will be tested for effectiveness, and treatment heterogeneity will be investigated to identify which veterans may respond best to a given pathway. Health care utilization patterns (including opioid use) will also be compared between care pathways. Therefore, the AIM-Back trial will provide important information that can inform the future delivery of nonpharmacologic treatment of LBP.

Implementation and Policy Recommendations from the VHA State-of-the-Art Conference on Strategies to Improve Opioid Safety

Evidence-based treatment of opioid use disorder, the prevention of opioid overdose and other opioid-related harms, and safe and effective pain management are priorities for the Veterans Health Administration (VHA). The VHA Office of Health Services Research and Development hosted a State-of-the-Art Conference on "Effective Management of Pain and Addiction: Strategies to Improve Opioid Safety" on September 10-11, 2019. This conference convened a multidisciplinary group to discuss and achieve consensus on a research agenda and on implementation and policy recommendations to improve opioid safety for Veterans. Participants were organized into three workgroups: (1) managing opioid use disorder; (2) Long-term opioid therapy and opioid tapering; (3) managing co-occurring pain and substance use disorder. Here we summarize the implementation and policy recommendations of each workgroup and highlight important cross-cutting issues related to telehealth, care coordination, and stepped care model implementation.

App-Based Pain Management and Opioid Education Program for Patients in Clinic Waiting Rooms

BACKGROUND

Best approaches to delivering patient education related to pain management and opioid safety are understudied.

AIMS

This study assessed the feasibility, acceptability, and preliminary patient-reported impact of an app-based patient pain education program.

DESIGN

Pilot study with data collection occurring on 43 weekdays between August 2019-February 2020.

SETTING

Waiting rooms at the pain clinic and a primary care medical home within two military treatment facilities.

PARTICIPANTS

Military health system beneficiaries seeking general care at the primary care medical home or pain-specific care at the pain clinic.

METHODS

The Joint Pain Education and Project curriculum includes patient-focused videos describing the biopsychosocial aspects of pain and pain management, medication take-back and safe disposal, and multidimensional pain assessments. The app-based videos were available on tablets in the waiting rooms for patients to view and complete surveys on after.

RESULTS

Overall, 152 patients viewed the videos and completed surveys. Most viewers were interested in receiving other tablet-based health education while in the waiting room (62%). Most viewers found videos to be moderately or very helpful (73%) and were satisfied or very satisfied with the information provided (85%). Participants at the primary care medical home were more likely to find videos helpful compared to participants at the pain clinic (OR = 2.11; 95% CI: 1.07, 4.20; p = .03).

CONCLUSION

Implementing app-based pain management education is feasible across clinic settings and is well received by patients. Clinics should consider providing pain education across care setting, rather than just pain specialty clinics, to help foster discussions between clinicians and patients regarding pain management and opioid safety.

Adapting to disruption of research during the COVID-19 pandemic while testing nonpharmacological approaches to pain management

The COVID-19 pandemic has slowed research progress, with particularly disruptive effects on investigations of addressing urgent public health challenges, such as chronic pain. The National Institutes of Health (NIH) Department of Defense (DoD) Department of Veterans Affairs (VA) Pain Management Collaboratory (PMC) supports 11 large-scale, multisite, embedded pragmatic clinical trials (PCTs) in military and veteran health systems. The PMC rapidly developed and enacted a plan to address key issues in response to the COVID-19 pandemic. The PMC tracked and collaborated in developing plans for addressing COVID-19 impacts across multiple domains and characterized the impact of COVID-19 on PCT operations, including delays in recruitment and revisions of study protocols. A harmonized participant questionnaire will facilitate later meta-analyses and cross-study comparisons of the impact of COVID-19 across all 11 PCTs. The pandemic has affected intervention delivery, outcomes, regulatory and ethics issues, participant recruitment, and study design. The PMC took concrete steps to ensure scientific rigor while encouraging flexibility in the PCTs, while paying close attention to minimizing the burden on research participants, investigators, and clinical care teams. Sudden changes in the delivery of pain management interventions will probably alter treatment effects measured via PMC PCTs. Through the use of harmonized instruments and surveys, we are capturing these changes and plan to monitor the impact on research practices, as well as on health outcomes. Analyses of patient-reported measures over time will inform potential relationships between chronic pain, mental health, and various socioeconomic stressors common among Americans during the COVID-19 pandemic.

Does Offering Battlefield Acupuncture Lead to Subsequent Use of Traditional Acupuncture?

OBJECTIVES

Veterans Health Administration encourages auricular acupuncture (Battlefield Acupuncture/BFA) as a nonpharmacologic approach to pain management. Qualitative reports highlighted a "gateway hypothesis": providing BFA can lead to additional nonpharmacologic treatments. This analysis examines subsequent use of traditional acupuncture.

RESEARCH DESIGN

Cohort study of Veterans treated with BFA and a propensity score matched comparison group with a 3-month follow-up period to identify subsequent use of traditional acupuncture. Matching variables included pain, comorbidity, and demographics, with further adjustment in multivariate regression analysis.

SUBJECTS

We identified 41,234 patients who used BFA across 130 Veterans Health Administration medical facilities between October 1, 2016 and March 31, 2019. These patients were matched 2:1 on Veterans who used VA care but not BFA during the same period resulting in a population of 24,037 BFA users and a comparison cohort of 40,358 non-BFA users. Patients with prior use of traditional acupuncture were excluded.

RESULTS

Among Veterans receiving BFA, 9.5% subsequently used traditional acupuncture compared with 0.9% of non-BFA users (P<0.001). In adjusted analysis, accounting for patient characteristics and regional availability of traditional acupuncture, patients who used BFA had 10.9 times greater odds (95% confidence interval, 8.67-12.24) of subsequent traditional acupuncture use.

CONCLUSIONS

Providing BFA, which is easy to administer during a patient visit and does not require providers be formally certified, led to a substantial increase in use of traditional acupuncture. These findings suggest that the value of offering BFA may not only be its immediate potential for pain relief but also subsequent engagement in additional therapies.

Opioid use disorders, psychiatric comorbidities, and risk for suicide attempts among veterans seeking pain care

BACKGROUND

The purpose of this study was to assess the associations of comorbid opioid use disorders and psychiatric disorders with suicide attempts among veterans seeking pain care.

METHODS

The cohort (N = 226 444) was selected by identifying pain care initiation from 2012 to 2014 using national Veterans Health Administration (VHA) data. Data on opioid use disorders (OUD), psychiatric disorders, medical comorbidity, demographics at baseline, and suicide attempts in the year following the initiation of pain care were extracted from VHA databases. Relative excess risk due to interaction (RERI) was used to assess departure from additivity of effects.

RESULTS

Adjusted models indicated that both comorbid OUD and depression (RERI = 1.07) and comorbid OUD and AUD (RERI = 1.23) were significantly associated with additive risk of suicide attempt. In adjusted multiplicative interaction models, only comorbid OUD and bipolar disorder was significantly associated with suicide attempts; however, this association was protective (HR = 0.54).

CONCLUSIONS

The current findings highlight the importance of addressing opioid use disorders and alcohol use disorders and depression together to mitigate the risk of suicidal behavior.

Patient Feedback on the Effectiveness of Auricular Acupuncture on Pain in Routine Clinical Care: The Experience of 11,406 Veterans

OBJECTIVES

Veterans Health Administration (VHA) launched a national initiative to train providers in a specific, protocolized auricular acupuncture treatment (also called Battlefield Acupuncture or BFA) as a nonpharmacological approach to pain management. This evaluation assessed the real-world effectiveness of BFA on immediate pain relief and identified subgroups of patients for whom BFA is most effective.

RESEARCH DESIGN

In a cross-sectional cohort study, electronic medical record data for 11,406 Veterans treated with BFA at 57 VHA medical centers between October 2016 and September 2018 was analyzed. The multivariate analysis incorporated data on pain history, change in pain level on an 11-point scale, complications, and demographic information.

METHODS

A total of 11,406 Veterans were treated with BFA at 57 VHA medical centers between October 2016 and September 2018 and had effectiveness data recorded in their electronic medical record.

RESULTS

More than 3 quarters experienced immediate decreases in pain following administration of BFA, with nearly 60% reported experiencing a minimal clinically important difference in pain intensity. The average decrease in pain intensity was -2.5 points (SD=2.2) at the initial BFA treatment, and -2.2 points (SD=2.0) at subsequent treatments. BFA was effective across a wide range of Veterans with many having preexisting chronic pain, or physical, or psychological comorbid conditions. Veterans with opioid use in the year before BFA experienced less improvement, with pain intensity scores improving more among Veterans who had not recently used opioids.

CONCLUSION

VHA's rapid expansion of training providers to offer BFA as a nonpharmacological approach to pain management has benefited many Veterans.

Treatment of a Large Cohort of Veterans Experiencing Musculoskeletal Disorders with Spinal Cord Stimulation in the Veterans Health Administration: Veteran Characteristics and Outcomes

OBJECTIVE

Spinal cord stimulator (SCS) implantation is used to treat chronic pain, including painful musculoskeletal disorders (MSDs). This study examined the characteristics and outcomes of veterans receiving SCSs in Veterans Health Administration (VHA) facilities.

METHODS

The sample was drawn from the MSD Cohort and limited to three MSDs with the highest number of implants (N=815,475). There were 1490 veterans with these conditions who received SCS implants from 2000 to 2012, of which 95% (n=1414) had pain intensity numeric rating scale (NRS) data both pre- and post-implant.

RESULTS

Veterans who were 35-44 years old, White, and married reported higher pain NRS ratings, had comorbid inclusion diagnoses, had no medical comorbidities, had a BMI 25-29.9, or had a depressive disorder diagnosis were more likely to receive an SCS. Veterans 55+ years old or with an alcohol or substance use disorder were less likely to receive an SCS. Over 90% of those receiving an SCS were prescribed opioids in the year prior to implant. Veterans who had a presurgical pain score ≥4 had a clinically meaningful decrease in their pain score in the year following their 90-day recovery period (Day 91-456) greater than expected by chance alone. Similarly, there was a significant decrease in the percent of veterans receiving opioid therapy (92.4% vs 86.6%, p<0.0001) and a significant overall decrease in opioid dose [morphine equivalent dose per day (MEDD) =26.48 vs MEDD=22.59, p<0.0003].

CONCLUSION

Results offer evidence of benefit for some veterans with the examined conditions. Given known risks of opioid therapy, the reduction is an important potential benefit of SCS implants.

Pain and Psychological Outcomes Among Iraq and Afghanistan Veterans with Chronic Pain and PTSD: ESCAPE Trial Longitudinal Results

Objective

To compare pain and psychological outcomes in veterans with chronic musculoskeletal pain and comorbid post-traumatic stress disorder (PTSD) or pain alone and to determine if veterans with comorbidity respond differently to a stepped-care intervention than those with pain alone.

Design

Secondary analysis of data from the Evaluation of Stepped Care for Chronic Pain (ESCAPE) trial.

Setting

Six Veterans Health Affairs clinics.

Subjects

Iraq and Afghanistan veterans (N = 222) with chronic musculoskeletal pain.

Methods

Longitudinal analysis of veterans with chronic musculoskeletal pain and PTSD or pain alone and available baseline and nine-month trial data. Participants randomized to either usual care or a stepped-care intervention were analyzed. The pain–PTSD comorbidity group screened positive for PTSD and had a PTSD Checklist–Civilian score ≥41 at baseline.

Results

T tests demonstrated statistically significant differences and worse outcomes on pain severity, pain cognitions, and psychological outcomes in veterans with comorbid pain and PTSD compared with those with pain alone. Analysis of covariance (ANCOVA) modeling change scores from baseline to nine months indicated no statistically significant differences, controlling for PTSD, on pain severity, pain centrality, or pain self-efficacy. Significant differences emerged for pain catastrophizing (t = 3.10, P &lt; 0.01), depression (t = 3.39, P &lt; 0.001), and anxiety (t = 3.80, P &lt; 0.001). The interaction between PTSD and the stepped-care intervention was not significant.

Conclusions

Veterans with the pain–PTSD comorbidity demonstrated worse pain and psychological outcomes than those with chronic pain alone. These findings indicate a more intense chronic pain experience for veterans when PTSD co-occurs with pain. PTSD did not lead to a differential response to a stepped-care intervention.

A virtual reality intervention for fear of movement for Veterans with chronic pain: protocol for a feasibility study

BACKGROUND

A key concern for people with chronic pain is experiencing increased pain and/or re-injury. Consequently, individuals with chronic pain can develop a maladaptive fear of movement that leads to adverse functional consequences. A primary goal of chronic pain rehabilitation is re-engagement in feared movements through exposure. This is often challenging since safe movement can be uncomfortable. Virtual environments provide a promising opportunity to safely and gradually expose Veterans to movements that are avoided in the real world. The current study will utilize multiple virtual reality (VR) applications (APPs) of varying the intensity levels ranging from passive distraction from pain to active exposure to feared movement. The primary aims of this pilot are to examine VR as an adjunctive nonpharmacological intervention to assist with the adoption and implementation of skills to decrease fear of movement and increase overall functioning among Veterans with chronic pain. Second, to build a hierarchy of VR APPs to assist in gradual exposure to feared movements.

METHODS

This study will be conducted in the Chronic Pain Rehabilitation Program (CPRP) at the James A. Haley Veterans Hospital, a unique inpatient program within the VA system. Participants will include up to 20 Veterans who receive a VR intervention as part of their physical therapy. A rating form containing qualitative and quantitative experiences will be administered following each VR session to assess feasibility and to provide descriptive information for the proposed hierarchy. Effect sizes will be calculated from intake and discharge measures for the primary outcome fear of movement and secondary pain and functional outcomes.

DISCUSSION

This study will inform the feasibility of a randomized controlled trial examining the clinical utility of using VR to reduce fear of movement and increase function among Veterans with chronic pain. VR has the advantage of being easily implemented both within VA healthcare settings as well as in Veterans' own residences, where engagement in ongoing self-management approaches is often most challenging. Presumably, VR that is matched to patient needs, progresses in intensity, immerses Veterans in the applications, and is perceived positively by Veterans, will result in positive functional outcomes.

Project STEP: Implementing the Veterans Health Administration's Stepped Care Model of Pain Management

Objective

The "stepped care model of pain management" (SCM-PM) prioritizes the role of primary care providers in optimizing pharmacological management and timely and equitable access to patient-centered, evidence-based nonpharmacological approaches, when indicated. Over the past several years, the Veterans Health Administration (VHA) has supported implementation of SCM-PM, but few data exist regarding changes in pain care resulting from implementation. We examined trends in prescribing and referral practices of primary care providers with hypotheses of decreased opioid prescribing, increased nonopioid prescribing, and increased referrals to specialty care for nonpharmacological services.

Design

An initiative was designed to foster implementation and systematic evaluation of the SCM-PM over a five-year period at the VA Connecticut Healthcare System (VACHS) while fostering collaborative, partnered initiatives to promote organizational improvements in the delivery of pain care.

Subjects

Participants were veterans receiving care at VACHS with at least one pain intensity rating ≥4/10 over the course of the study period (7/2008-6/2013).

Methods

We used electronic health record data to examine changes in indicators of pain care including pharmacy and health care utilization data.

Results

We observed hypothesized changes in long-term opioid and nonopioid analgesic prescribing and increased utilization of nonpharmacological treatments such as physical therapy, occupational therapy, and clinical health psychology.

Conclusions

Through a multifaceted comprehensive implementation approach, primary care providers demonstrated increases in guideline-concordant pain care practices. Findings suggest that engagement of interdisciplinary teams and partnerships to promote organizational improvements is a useful strategy to increase the use of integrated, multimodal pain care for veterans, consistent with VHA's SCM-PM.

Analysis of State Insurance Coverage for Nonpharmacologic Treatment of Low Back Pain as Recommended by the American College of Physicians Guidelines

Background

In 2017, the American College of Physicians (ACP) released guidelines encouraging nonpharmacologic treatment of chronic low back pain (LBP). These guidelines recommended utilization of treatments including multidisciplinary rehabilitation, acupuncture, mindfulness-based stress reduction (MBSR), tai chi, yoga, progressive relaxation, biofeedback, cognitive behavioral therapy (CBT), and spinal manipulation.

Objective

We aimed to determine status of insurance coverage status for multiple nonpharmacological pain therapies based on the 2017 Essential Health Benefits (EHB) benchmark plans across all states.

Methods

The 2017 EHB benchmark plans represent the minimum benefits required in all new policies in the individual and small group health insurance markets and were reviewed for coverage of treatments for LBP recommended by the ACP guidelines. Additionally, plans were reviewed for limitations and exclusionary criteria.

Results

In nearly all state-based coverage policies, chronic pain management and multidisciplinary rehabilitation were not addressed. Coverage was most extensive (supported by 46 states) for spinal manipulation. Acupuncture, massage, and biofeedback were each covered by fewer than 10 states, while MBSR, tai chi, and yoga were not covered by any states. Behavioral health treatment (CBT and biofeedback) coverage was often covered solely for mental health diagnoses, although excluded for treating LBP.

Conclusion

Other than spinal manipulation, evidence-based, nonpharmacological therapies recommended by the 2017 ACP guidelines were routinely excluded from EHB benchmark plans. Insurance coverage discourages multidisciplinary rehabilitation for chronic pain management by providing ambiguous guidelines, restricting ongoing treatments, and excluding behavioral or complementary therapy despite a cohesive evidence base. Better EHB plan coverage of nondrug therapies may be a strategy to mitigate the opioid crisis. Recommendations that reflect current research-based findings are provided to update chronic pain policy statements.

Evaluation of Complementary and Integrative Health Approaches Among US Veterans with Musculoskeletal Pain Using Propensity Score Methods

Objectives

To examine the treatment effectiveness of complementary and integrative health approaches (CIH) on chronic pain using Propensity Score (PS) methods.

Design, Settings, and Participants

A retrospective cohort of 309,277 veterans with chronic musculoskeletal pain assessed over three years after initial diagnosis.

Methods

CIH exposure was defined as one or more clinical visits for massage, acupuncture, or chiropractic care. The treatment effect of CIH on self-rated pain intensity was examined using a longitudinal model. PS-matching and inverse probability of treatment weighting (IPTW) were used to account for potential selection and confounding biases.

Results

At baseline, veterans with (7,621) and without (301,656) CIH exposure differed significantly in 21 out of 35 covariates. During the follow-up period, on average CIH recipients had 0.83 (95% confidence interval [CI] = 0.77 to 0.89) points higher pain intensity ratings (range = 0-10) than nonrecipients. This apparent unfavorable effect size was reduced to 0.37 (95% CI = 0.28 to 0.45) after PS matching, 0.36 (95% CI = 0.29 to 0.44) with IPTW on the treated (IPTW-T) weighting, and diminished to null when integrating IPTW-T with PS matching (0.004, 95% CI = -0.09 to 0.10). An alternative IPTW model and conventional covariate adjustment appeared least powerful in terms of potential bias reduction. Sensitivity analyses restricting the follow-up period to one year after CIH initiation derived consistent results.

Conclusions

PS-based causal methods successfully eliminated baseline difference between exposure groups in all measured covariates, yet they did not detect a significant difference in the self-rated pain intensity outcome between veterans who received CIHs and those who did not during the follow-up period.
