RESUMO
BACKGROUND: Yoga is effective for chronic low back pain (cLBP) in civilians but understudied among Veterans. OBJECTIVE: Determine whether yoga is more effective than an educational book for improving disability and pain among Veterans with cLBP. DESIGN, SETTING, AND PARTICIPANTS: Veterans diagnosed with cLBP at a VA medical center enrolled in a randomized controlled trial from March to December of 2015. INTERVENTIONS: Twelve weekly hatha yoga classes or education using The Back Pain Helpbook. MEASURES: Co-primary outcomes were changes from baseline at 12 weeks in back-related disability on the modified Roland Morris Disability Questionnaire and pain on the Defense & Veterans Pain Rating Scale. Secondary outcomes were global improvement, patient satisfaction, pain medication use, and post-traumatic stress symptoms. An intention-to-treat approach was used in primary analyses. RESULTS: One hundred twenty Veterans (mean age, 55.5 [SD = 16.9]; 11 [9%] women; mean number of chronic conditions, 5.5) were randomized to yoga (n = 62) and education (n = 58). At 12 weeks, reductions in back-related disability in yoga (mean difference [MD] = - 3.50, 95% CI: - 5.03, - 1.97) were not significantly different than education (MD = - 2.55, 95% CI: - 4.10, - 0.99; between-group difference: - 0.95 [95% CI: - 3.14, 1.23], p = 0.39). For pain, there was no significant difference between yoga (MD = - 1.01, 95% CI: - 1.67, - 0.35) and education (MD = - 0.81, 95% CI: - 1.36, - 0.27; between-group difference: - 0.20, 95% CI: - 1.06, 0.66, p = 0.65). More yoga than education participants reported being very much or extremely improved (39% vs 19%, OR = 3.71, 95% CI: 1.37, 10.02, p = 0.01) and very satisfied with treatment (60% vs 31%, OR = 4.28, 95% CI: 1.70, 10.77, p = 0.002). No differences in pain medication use or post-traumatic stress symptoms were observed at 12 weeks. No serious adverse events were reported in either group. CONCLUSION: Twelve weekly yoga classes were not more effective than an education intervention for improving pain or disability outcomes among mostly older male Veterans with cLBP and multiple comorbid health conditions. GOV IDENTIFIER: NCT02224183.

OBJECTIVE: We assessed whether race or ethnicity was associated with the incidence of high-impact chronic low back pain (cLBP) among adults consulting a primary care provider for acute low back pain (aLBP). METHODS: In this secondary analysis of a prospective cohort study, patients with aLBP were identified through screening at seventy-seven primary care practices from four geographic regions. Incidence of high-impact cLBP was defined as the subset of patients with cLBP and at least moderate disability on Oswestry Disability Index [ODI >30]) at 6 months. General linear mixed models provided adjusted estimates of association between race/ethnicity and high-impact cLBP. RESULTS: We identified 9,088 patients with aLBP (81.3% White; 14.3% Black; 4.4% Hispanic). Black/Hispanic patients compared to White patients, were younger and more likely to be female, obese, have Medicaid insurance, worse disability on ODI, and were at higher risk of persistent disability on STarT Back Tool (all P < .0001). At 6 months, more Black and Hispanic patients reported high-impact cLBP (30% and 25%, respectively) compared to White patients (15%, P < .0001, n = 5,035). After adjusting for measured differences in socioeconomic and back-related risk factors, compared to White patients, the increased odds of high-impact cLBP remained statistically significant for Black but not Hispanic patients (adjusted odds ration [aOR] = 1.40, 95% confidence interval [CI]: 1.05-1.87 and aOR = 1.25, 95%CI: 0.83-1.90, respectively). CONCLUSIONS: We observed an increased incidence of high-impact cLBP among Black and Hispanic patients compared to White patients. This disparity was partly explained by racial/ethnic differences in socioeconomic and back-related risk factors. Interventions that target these factors to reduce pain-related disparities should be evaluated. CLINICALTRIALS.GOV IDENTIFIER: NCT02647658.

Objectives. To describe the types of health remedies collected during poisoning investigations in New York City over a 10-year period that were found to contain high levels of lead, mercury, or arsenic. Methods. Between 2010 and 2019, the New York City Department of Health and Mental Hygiene collected 584 samples of health remedies during poisoning investigations and store surveys for lead, mercury, or arsenic analysis. Results. There was a significant association between blood lead levels and estimated cumulative daily lead exposures among adult users of rasa shastra Ayurvedic medications. Also, average blood lead levels among adult rasa shastra users were significantly higher than levels among those using other types of non-Ayurvedic health remedies. Conclusions. Rasa shastra Ayurvedic medications can contain very high levels of lead, mercury, and arsenic. This underscores the importance of screening for lead, mercury, and arsenic exposures within at-risk populations. Public Health Implications. The general ease of accessibility to rasa shastra medications raises concerns. There is a need for systemic change that results in primary prevention, that is, removal of the source through policy development and regulatory enforcement in the country of origin.

OBJECTIVE: We evaluated exercise interventions for cognitive appraisal of chronic low back pain (cLBP) in an underserved population. METHODS: We conducted a secondary analysis of the Back to Health Trial, showing yoga to be noninferior to physical therapy (PT) for pain and function outcomes among adults with cLBP (n = 320) recruited from primary care clinics with predominantly low-income patients. Participants were randomized to 12 weeks of yoga, PT, or education. Cognitive appraisal was assessed with the Pain Self-Efficacy Questionnaire (PSEQ), Coping Strategies Questionnaire (CSQ), and Fear-Avoidance Beliefs Questionnaire (FABQ). Using multiple imputation and linear regression, we estimated within- and between-group changes in cognitive appraisal at 12 and 52 weeks, with baseline and the education group as references. RESULTS: Participants (mean age = 46 years) were majority female (64%) and majority Black (57%), and 54% had an annual household income <$30,000. All three groups showed improvements in PSEQ (range 0-60) at 12 weeks (yoga, mean difference [MD] = 7.0, 95% confidence interval [CI]: 4.9, 9.0; PT, MD = 6.9, 95% CI: 4.7 to 9.1; and education, MD = 3.4, 95% CI: 0.54 to 6.3), with yoga and PT improvements being clinically meaningful. At 12 weeks, improvements in catastrophizing (CSQ, range 0-36) were largest in the yoga and PT groups (MD = -3.0, 95% CI: -4.4 to -1.6; MD = -2.7, 95% CI: -4.2 to -1.2, respectively). Changes in FABQ were small. No statistically significant between-group differences were observed on PSEQ, CSQ, or FABQ at either time point. Many of the changes observed at 12 weeks were sustained at 52 weeks. CONCLUSION: All three interventions were associated with improvements in self-efficacy and catastrophizing among low-income, racially diverse adults with cLBP. TRIAL REGISTRATION: ClinicalTrials.gov identifier NCT01343927.

BACKGROUND: Back pain is the most common cause of disability worldwide. While disability generally is associated with greater mortality, the association between back pain and mortality is unclear. Our objective was to examine whether back pain is associated with increased mortality risk and whether this association varies by age, sex, and back pain severity. METHODS: A systematic search of published literature was conducted using PubMed, Web of Science, and Embase databases from inception through March 2019. We included English-language prospective cohort studies evaluating the association of back pain with all-cause mortality with follow-up periods >5 years. Three reviewers independently screened studies, abstracted data, and appraised risk of bias using the Quality in Prognosis Studies (QUIPS) tool. A random-effects meta-analysis estimated combined odds ratios (OR) and 95% confidence intervals (CI), using the most adjusted model from each study. Potential effect modification by a priori hypothesized factors (age, sex, and back pain severity) was evaluated with meta-regression and stratified estimates. RESULTS: We identified eleven studies with 81,337 participants. Follow-up periods ranged from 5 to 23 years. The presence of any back pain, compared to none, was not associated with an increase in mortality (OR, 1.06; 95% CI, 0.97 to 1.16). However, back pain was associated with mortality in studies of women (OR, 1.22; 95% CI, 1.02 to 1.46) and among adults with more severe back pain (OR, 1.26; 95% CI, 1.14 to 1.40). CONCLUSION: Back pain was associated with a modest increase in all-cause mortality among women and those with more severe back pain.

PURPOSE: To identify baseline characteristics of adults with chronic low back pain (cLBP) that predict response (i.e., a clinically important improvement) and/or modify treatment effect across three nonpharmacologic interventions. DESIGN: Secondary analysis of a randomized controlled trial. SETTING: Academic safety net hospital and seven federally qualified community health centers. SUBJECTS: Adults with cLBP (N = 299). METHODS: We report patient characteristics that were predictors of response and/or modified treatment effect across three 12-week treatments: yoga, physical therapy [PT], and a self-care book. Using preselected characteristics, we used logistic regression to identify predictors of "response," defined as a ≥30% improvement in the Roland Morris Disability Questionnaire. Then, using "response" as our outcome, we identified baseline characteristics that were treatment effect modifiers by testing for statistical interaction (P < 0.05) across two comparisons: 1) yoga-or-PT vs self-care and 2) yoga vs PT. RESULTS: Overall, 39% (116/299) of participants were responders, with more responders in the yoga-or-PT group (42%) than the self-care (23%) group. There was no difference in proportion responding to yoga (48%) vs PT (37%, odds ratio [OR] = 1.5, 95% confidence interval = 0.88 - 2.6). Predictors of response included having more than a high school education, a higher income, employment, few depressive symptoms, lower perceived stress, few work-related fear avoidance beliefs, high pain self-efficacy, and being a nonsmoker. Effect modifiers included use of pain medication and fear avoidance beliefs related to physical activity (both P = 0.02 for interaction). When comparing yoga or PT with self-care, a greater proportion were responders among those using pain meds (OR = 5.3), which differed from those not taking pain meds (OR = 0.94) at baseline. We also found greater treatment response among those with lower (OR = 7.0), but not high (OR = 1.3), fear avoidance beliefs around physical activity. CONCLUSIONS: Our findings revealed important subgroups for whom referral to yoga or PT may improve cLBP outcomes.

OBJECTIVE: To determine and compare the effect of yoga, physical therapy (PT), and education on depressive and anxious symptoms in patients with chronic low back pain (CLBP). DESIGN: Secondary analysis of a randomized controlled trial. SETTING: Academic safety net hospital and 7 community health centers. PARTICIPANTS: A total of 320 adults with CLBP. INTERVENTION: Yoga classes, PT sessions, or an educational book. OUTCOME MEASURE: Depression and anxiety were measured using the Patient Health Questionnaire and Generalized Anxiety Disorder 7-item Scale, respectively, at baseline, 12, and 52 weeks. We identified baseline and midtreatment (6-wk) factors associated with clinically meaningful improvements in depressive (≥3 points) or anxious (≥2 points) symptoms at 12 weeks. RESULTS: Participants (female=64%; mean age, 46.0±10.7 years) were predominantly non-White (82%), low-income (<$30,000/year, 59%), and had not received a college degree (71%). Most participants had mild or worse depressive (60%) and anxious (50%) symptoms. At 12 weeks, yoga and PT participants experienced modest within-group improvements in depressive symptoms (mean difference [MD]=-1.23 [95% CI, -2.18 to -0.28]; MD=-1.01 [95% CI, -2.05 to -0.03], respectively). Compared with the education group, 12-week differences were not statistically significant, although trends favored yoga (MD=-0.71 [95% CI, -2.22 to 0.81]) and PT (MD= -0.32 [95% CI, -1.82 to 1.18]). At 12 weeks, improvements in anxious symptoms were only found in participants who had mild or moderate anxiety at baseline. Independent of treatment arm, participants who had 30% or greater improvement in pain or function midtreatment were more likely to have a clinically meaningful improvement in depressive symptoms (odds ratio [OR], 1.82 [95% CI, 1.03-3.22]; OR, 1.79 [95% CI, 1.06-3.04], respectively). CONCLUSIONS: In our secondary analysis we found that depression and anxiety, common in this sample of underserved adults with CLBP, may improve modestly with PT and yoga. However, effects were not superior to education. Improvements in pain and function are associated with a decrease in depressive symptoms. More research is needed to optimize the integration of physical and psychological well-being in PT and yoga.

OBJECTIVE: Perceived stress and musculoskeletal pain are common, especially in low-income populations. Studies evaluating treatments to reduce stress in patients with chronic pain are lacking. We aimed to quantify the effect of two evidence-based interventions for chronic low back pain (cLBP), yoga and physical therapy (PT), on perceived stress in adults with cLBP. METHODS: We used data from an assessor-blinded, parallel-group randomized controlled trial, which recruited predominantly low-income and racially diverse adults with cLBP. Participants (N = 320) were randomly assigned to 12 weeks of yoga, PT, or back pain education. We compared changes in the 10-item Perceived Stress Scale (PSS-10) from baseline to 12- and 52-week follow-up among yoga and PT participants with those receiving education. Subanalyses were conducted for participants with elevated pre-intervention perceived stress (PSS-10 score ≥17). We conducted sensitivity analyses using various imputation methods to account for potential biases in our estimates due to missing data. RESULTS: Among 248 participants (mean age = 46.4 years, 80% nonwhite) completing all three surveys, yoga and PT showed greater reductions in PSS-10 scores compared with education at 12 weeks (mean between-group difference = -2.6, 95% confidence interval [CI] = -4.5 to -0.66, and mean between-group difference = -2.4, 95% CI = -4.4 to -0.48, respectively). This effect was stronger among participants with elevated pre-intervention perceived stress. Between-group effects had attenuated by 52 weeks. Results were similar in sensitivity analyses. CONCLUSIONS: Yoga and PT were more effective than back pain education for reducing perceived stress among low-income adults with cLBP.

OBJECTIVE: To determine whether the initial care provider for neck pain was associated with opioid use for individuals with neck pain. DESIGN: Retrospective cohort study. SETTING: Marketscan research databases. PARTICIPANTS: Patients (N=427,966) with new-onset neck pain from 2010-2014. MAIN OUTCOME MEASURES: Opioid use was defined using retail pharmacy fills. We performed logistic regression analysis to assess the association between initial provider and opioid use. Adjusted odds ratios (ORs) with 95% confidence intervals (CIs) were calculated using bootstrapping logistic models. We performed propensity score matching as a robustness check on our findings. RESULTS: Compared to patients with neck pain who saw a primary health care provider, patients with neck pain who initially saw a conservative therapist were 72%-91% less likely to fill an opioid prescription in the first 30 days, and between 41%-87% less likely to continue filling prescriptions for 1 year. People with neck pain who initially saw emergency medicine physicians had the highest odds of opioid use during the first 30 days (OR, 3.58; 95% CI, 3.47-3.69; P<.001). CONCLUSIONS: A patient's initial clinical contact for neck pain may be an important opportunity to influence subsequent opioid use. Understanding more about the roles that conservative therapists play in the treatment of neck pain may be key in unlocking new ways to lessen the burden of opioid use in the United States.

BACKGROUND: Although risk-stratifying patients with acute lower back pain is a promising approach for improving long-term outcomes, efforts to implement stratified care in the US healthcare system have had limited success. The objectives of this process evaluation were to 1) examine variation in two essential processes, risk stratification of patients with low back pain and referral of high-risk patients to psychologically informed physical therapy and 2) identify barriers and facilitators related to the risk stratification and referral processes. METHODS: We used a sequential mixed methods study design to evaluate implementation of stratified care at 33 primary care clinics (17 intervention, 16 control) participating in a larger pragmatic trial. We used electronic health record data to calculate: 1) clinic-level risk stratification rates (proportion of patients with back pain seen in the clinic over the study period who completed risk stratification questionnaires), 2) rates of risk stratification across different points in the clinical workflow (front desk, rooming, and time with clinician), and 3) rates of referral of high-risk patients to psychologically informed physical therapy among intervention clinics. We purposively sampled 13 clinics for onsite observations, which occurred in month 24 of the 26-month study. RESULTS: The overall risk stratification rate across the 33 clinics was 37.8% (range: 14.7-64.7%). Rates were highest when patients were identified as having back pain by front desk staff (overall: 91.9%, range: 80.6-100%). Rates decreased as the patient moved further into the visit (rooming, 29.3% [range: 0-83.3%]; and time with clinician, 11.3% [range: 0-49.3%]. The overall rate of referrals of high-risk patients to psychologically informed physical therapy across the 17 intervention clinics was 42.1% (range: 8.3-70.8%). Barriers included staffs' knowledge and beliefs about the intervention, patients' needs, technology issues, lack of physician engagement, and lack of time. Adaptability of the processes was a facilitator. CONCLUSIONS: Adherence to key stratified care processes varied across primary care clinics and across points in the workflow. The observed variation suggests room for improvement. Future research is needed to build on this work and more rigorously test strategies for implementing stratified care for patients with low back pain in the US healthcare system. TRIAL REGISTRATION: Trial registration: ClinicalTrials.gov ( NCT02647658 ). Registered January 6, 2016.

BACKGROUND: The impact of back pain on disability in older women is well-understood, but the influence of back pain on mortality is unclear. OBJECTIVE: To examine whether back pain was associated with all-cause and cause-specific mortality in older women and mediation of this association by disability. DESIGN: Prospective cohort study. SETTING: The Study of Osteoporotic Fractures. PARTICIPANTS: Women aged 65 or older. MEASUREMENT: Our primary outcome, time to death, was assessed using all-cause and cause-specific adjusted Cox models. We used a four-category back pain exposure (no back pain, non-persistent, infrequent persistent, or frequent persistent back pain) that combined back pain frequency and persistence across baseline (1986-1988) and first follow-up (1989-1990) interviews. Disability measures (limitations of instrumental activities of daily living [IADL], slow chair stand time, and slow walking speed) from 1991 were considered a priori potential mediators. RESULTS: Of 8321 women (mean age 71.5, SD = 5.1), 4975 (56%) died over a median follow-up of 14.1 years. A higher proportion of women with frequent persistent back pain died (65.8%) than those with no back pain (53.5%). In the fully adjusted model, women with frequent persistent back pain had higher hazard of all-cause (hazard ratio [HR] = 1.24 [95% CI, 1.11-1.39]), cardiovascular (HR = 1.34 [CI, 1.12-1.62]), and cancer (HR = 1.33, [CI 1.03-1.71]) mortality. No association with mortality was observed for other back pain categories. In mediation analyses, IADL limitations explained 47% of the effect of persistent frequent back pain on all-cause mortality, slow chair stand time, and walking speed, explained 27% and 24% (all significant, p < 0.001), respectively. LIMITATIONS: Only white women were included. CONCLUSION: Frequent persistent back pain was associated with increased mortality in older women. Much of this association was mediated by disability.

BACKGROUND: Yoga is effective for mild to moderate chronic low back pain (cLBP), but its comparative effectiveness with physical therapy (PT) is unknown. Moreover, little is known about yoga's effectiveness in underserved patients with more severe functional disability and pain. OBJECTIVE: To determine whether yoga is noninferior to PT for cLBP. DESIGN: 12-week, single-blind, 3-group randomized noninferiority trial and subsequent 40-week maintenance phase. (ClinicalTrials.gov: NCT01343927). SETTING: Academic safety-net hospital and 7 affiliated community health centers. PARTICIPANTS: 320 predominantly low-income, racially diverse adults with nonspecific cLBP. INTERVENTION: Participants received 12 weekly yoga classes, 15 PT visits, or an educational book and newsletters. The maintenance phase compared yoga drop-in classes versus home practice and PT booster sessions versus home practice. MEASUREMENTS: Primary outcomes were back-related function, measured by the Roland Morris Disability Questionnaire (RMDQ), and pain, measured by an 11-point scale, at 12 weeks. Prespecified noninferiority margins were 1.5 (RMDQ) and 1.0 (pain). Secondary outcomes included pain medication use, global improvement, satisfaction with intervention, and health-related quality of life. RESULTS: One-sided 95% lower confidence limits were 0.83 (RMDQ) and 0.97 (pain), demonstrating noninferiority of yoga to PT. However, yoga was not superior to education for either outcome. Yoga and PT were similar for most secondary outcomes. Yoga and PT participants were 21 and 22 percentage points less likely, respectively, than education participants to use pain medication at 12 weeks. Improvements in yoga and PT groups were maintained at 1 year with no differences between maintenance strategies. Frequency of adverse events, mostly mild self-limited joint and back pain, did not differ between the yoga and PT groups. LIMITATIONS: Participants were not blinded to treatment assignment. The PT group had disproportionate loss to follow-up. CONCLUSION: A manualized yoga program for nonspecific cLBP was noninferior to PT for function and pain.

Introduction: The popularity of yoga has surged in recent years; however, yoga practitioners have remained a largely homogenous population. Research reflects that most practitioners are of a higher socioeconomic status. There are access barriers to yoga for lower income individuals, likely due to factors such as financial constraints and logistical challenges. The primary goal of this review was to synthesize literature on yoga research among low-income populations and better understand the feasibility and acceptability of such interventions. A secondary goal was to assess the consistency of metrics for reporting feasibility and acceptability across such studies using the CheckList Standardizing the Reporting of Interventions for Yoga (CLARIFY) guidelines as a framework. Third, the authors sought to propose additional standardized CLARIFY guidelines that may enhance reporting on the diversity of yoga research populations, adherence, and retention. Methods: The electronic databases PubMed, PsycINFO, Cochrane Central Register of Controlled Trials, and Google Scholar were searched in May 2022 using a prespecified search string. Articles assessing a yoga intervention in predominantly low-income adult populations were deemed eligible for inclusion. Results: The search resulted in 512 potential articles. Eleven were deemed eligible for inclusion. The included studies reported mostly positive effects of yoga on the target outcome (i.e., pain/disability, quality of life/wellness, and psychiatric symptoms). Recruitment and retention data showed generally good attendance and high study completion rates. Common study design components included recruitment embedded within preexisting medical settings, proximal yoga locations, and mitigation of yoga-related costs. Finally, the authors noted inconsistency in the reporting of adherence, retention, and other sociodemographic characteristics of participants and yoga instructors (e.g., race, ethnicity, and income). Discussion: Yoga may promote physical and mental health for low-income individuals. Important facilitators to access are noted, such as proximal study settings, as well as barriers such as the need for childcare that can be addressed in future research. In addition, several study design considerations could help address the specific needs of low-income participants in yoga research, such as compensating participants, recruiting within existing medical settings, and providing yoga-related equipment at no cost. Finally, the authors suggest specific ways to enhance reporting of study metrics related to socioeconomic diversity, by adding to the preexisting CLARIFY guidelines.

BACKGROUND: Clinical practice guidelines encourage primary care providers (PCPs) to recommend nonpharmacologic treatment as first-line therapy for low back pain (LBP). However, the determinants of nonpharmacologic treatment use for LBP in primary care remain unclear, particularly in low-income settings. OBJECTIVE: To pilot a framework-informed interview guide and codebook to explore determinants of nonpharmacologic treatment use in primary care. METHODS: In this qualitative interview study, we enrolled PCPs and community health workers (CHWs) from four primary care clinics at a safety net hospital. A semistructured interview guide informed by the Consolidated Framework for Implementation Research (CFIR) guided inquiry on barriers/facilitators to nonpharmacologic treatments for LBP (eg, acupuncture, chiropractic care, physical therapy). We included questions on whether current CHW roles may address barriers to nonpharmacologic treatment use. Interviews were audio-recorded, transcribed verbatim, and independently coded by four investigators. An a priori codebook composed of CFIR determinants and known CHW roles guided deductive content analysis to identify major themes. RESULTS: Eight individuals (six PCPs, two CHWs; age range: 32-51 years, five female) participated in hour-long interviews. Half had worked at the hospital for ≥15 years and all reported seeing patients with LBP (range: 2-20 patients per week). All participants identified the following CFIR factors as barriers/facilitators: nonpharmacologic treatment characteristics (perceived cost, relative advantage compared to other treatments); outer setting (patient needs/resources, limited connections with community-based nonpharmacologic treatment) and PCP characteristics (attitudes/beliefs about nonpharmacologic treatments). Although participants indicated several CHW roles could be adapted to address barriers (eg, care coordination, resource linking, case management), other roles seemed less feasible (eg, targeted health education) in our health care system. CONCLUSIONS: Preliminary insight on key determinants of nonpharmacologic treatments for LBP should be further examined in large multisite studies. Future studies may also determine whether a CHW-led strategy can improve nonpharmacologic treatment access and clinical outcomes in primary care.
RESUMO
PURPOSE: Primary care physicians (PCPs) often face a complex intersection of patient expectations, evidence, and policy that influences their care recommendations for acute low back pain (aLBP). The purpose of this study was to elucidate patterns of PCP orders for patients with aLBP, identify the most common patterns, and describe patient clinical and demographic characteristics associated with patterns of aLBP care. METHODS: This prospective cohort study included 9574 aLBP patients presenting to 1 of 77 primary care practices in 4 geographic locations in the United States. We performed a cluster analysis of PCP orders extracted from electronic health records within the first 21 days of an initial visit for aLBP. RESULTS: 1401 (15%) patients did not receive a PCP order related to back pain within the first 21 days of their initial visit. These patients predominantly had aLBP without leg pain, less back-related disability, and were at low-risk for persistent disability. Of the remaining 8146 patients, we found 4 distinct order patterns: combined nonpharmacologic and first-line medication (44%); second-line medication (39%); imaging (10%); and specialty referral (7%). Among all patients, 29% received solely 1 order from their PCP. PCPs more often combined different guideline concordant and discordant orders. Patients with higher self-reported disability and psychological distress were more likely to receive guideline discordant care. CONCLUSION: Guideline discordant orders such as steroids and NSAIDS are often combined with guideline recommended orders such as physical therapy. Further defining patient, clinician, and health care setting characteristics associated with discordant care would inform targeted efforts for deimplementation initiatives.

BACKGROUND: Chronic low back pain (cLBP) is a complex condition that is physically and psychologically debilitating, with vulnerable populations experiencing more severe outcomes. Physical therapy (PT) includes evidence-based treatments that can reduce disability, however the experience of PT can vary amongst different populations. Empirical evidence is largely based on majority samples that are predominantly white with high educational attainment. Little is known regarding how people from vulnerable groups (e.g. low income and racial minority) experience physical therapy treatment for low back pain. OBJECTIVE: To describe the experience of physical therapy in a predominantly low-income and minority population with cLBP. METHODS: This qualitative study was embedded within a randomized controlled trial for patients with cLBP in urban, underserved communities. We used a convenience sample to interview 12 participants from the 102 who participated in the PT arm of the trial and then performed thematic analysis to describe their experience. RESULTS: Three major themes emerged: 1) Empowerment through education and exercise; 2) Interconnectedness to providers and other patients; and 3) Improvements in pain, body mechanics, and mood. Divergent cases were few however centered around a lack of improvement in pain or an absence of connection with the therapist. Within the first theme a prevailing sub-theme emerged that aligned with Bandura's theory of self-efficacy: 1) Mastery of experience; 2) Verbal persuasion; 3) Vicarious experience; and 4) Physiological state. CONCLUSIONS: Our participants' insight highlighted the value of cognitive-emotional and interpersonal dimensions of PT. These may be particularly important components of PT in populations that have experienced systemic distrust in providers and disparities in services. Future work could use Bandura's model of self-efficacy to build a PT intervention comprised of fear-based movement exercises, interconnectedness, a strong therapeutic alliance, and mindfulness techniques.

Introduction: The 1978 Alma Ata Declaration initiated international recognition of non-biomedical healing systems and their relevance for primary health. World Health Assembly (WHA) resolutions have called for the study and inclusion of traditional and complementary medicine (T&CM) into national health systems through policy development. The increased public, political, and scholarly attention given to T&CM has focused on clinical efficacy, cost-effectiveness, mechanisms of action, consumer demand, and supply-side regulation. Although >50% of WHO member states have T&CM policies, scant research has focused on these policies and their public health implications. This paper defines a novel term "therapeutic pluralism," and it aims at characterizing related policies in Latin America. Methods: A qualitative content analysis of Latin American therapeutic pluralism policies was performed. Policies' characteristics and the reported social, political, and economic forces that have made possible their development were assessed. Pre-defined policy features were categorized on an MS-Excel; in-depth text analyses were conducted in NVivo. Analyses followed the steps described by Bengtsson: decontextualization, recontextualization, categorization, and compilation. Results: Seventy-four (74) policy documents from 16 of the 20 sovereign Latin American countries were included. Mechanisms for policy enactment included: Constitution, National Law, National Policy, National Healthcare Model, National Program Guideline, Specific Regulatory Norms, and Supporting Legislation, Policies, and Norms. We propose a four-category typology of policy approaches in Latin America: Health Services-centered, Model of Care-based, Participatory, and Indigenous People-focused. Common themes countries used when justifying developing these policies included: benefits to the health system, legal and political mandates, supply and demand, and culture and identity. Social forces these policies referenced as influencing their development included: pluralism, self-determination and autonomy, anticapitalism and decolonization, safeguarding cultural identity, bridging cultural barriers, and sustainability. Conclusion: Policy approaches to therapeutic pluralism in Latin America go beyond integrating non-biomedical interventions into health services; they offer perspectives for transforming health systems. Characterizing these approaches has implications for policy development, implementation, evaluation, international collaboration, the development of technical cooperation tools and frameworks, and research.

ABSTRACT: Treatment effect modifiers identify patient characteristics associated with treatment responses. The purpose of this secondary analysis was to identify potential treatment effect modifiers for disability from the TARGET trial that compared usual care (control) with usual care + psychologically informed physical therapy (PIPT). The sample consisted of a STarT Back tool identified high-risk patients with acute low back pain that completed Oswestry Disability Index (ODI) data at index visit and 6 months later (n = 1250). Candidate treatment effect modifiers were identified a priori and informed by the literature. Linear mixed models tested for treatment effect modification through tests of statistical interaction. All statistical interactions ( P ≤ 0.20) were stratified by modifier to inspect for specific effects ( P ≤ 0.05). Smoking was identified as a potential effect modifier (treatment * smoking interaction, P = 0.08). In participants who were smokers, the effect of PIPT was (ODI = 5.5; 95% CI: 0.6-10.4; P = 0.03) compared with usual care. In participants who were nonsmokers, the effect of PIPT was (ODI = 1.5; 95% CI: -1.4 to 4.4; P = 0.31) compared with usual care. Pain medication was also identified as a potential effect modifier (treatment × pain medication interaction, P = 0.10). In participants prescribed ≥3 pain medications, the effect of PIPT was (ODI = 7.1; 95% CI: -0.1 to 14.2; P = 0.05) compared with usual care. The PIPT effect for participants prescribed no pain medication was (ODI = 3.5; 95% CI: -0.4 to 7.4; P = 0.08) and for participants prescribed 1 to 2 pain medications was (ODI = 0.6; 95% CI: -2.5 to 3.7; P = 0.70) when compared with usual care. These findings may be used for generating hypotheses and planning future clinical trials investigating the effectiveness of tailored application of PIPT.

OBJECTIVE: To investigate whether indirect effects via psychological mechanisms explain the effects of physical therapy (PT) or yoga versus education on back-related outcomes. DESIGN: Mediation analyses using data from a randomized controlled trial of PT, yoga, and education interventions for chronic low back pain. METHODS: Primary outcomes were changes in back-related pain on the 11-point numeric rating scale and disability on the modified 23-point Roland-Morris Disability Questionnaire, measured at 52 weeks after randomization. Hypothesized mediators were 12-week changes in pain self-efficacy, fear-avoidance beliefs, depression, anxiety, perceived stress, and sleep quality. We used causal mediation analysis to estimate the total effect, direct effect, indirect effect, and proportion mediated. RESULTS: We analyzed data from 230 adults (mean age = 46.2 years, 69.6% female, 79.6% non-White). In the PT-versus-education model, when the mediator was perceived stress, the total effect on disability was 2.6 points (95% confidence interval [CI]: 0.3, 4.9) and decomposed into a direct effect of 1.7 points (95% CI: -0.4, 3.8) and an indirect effect 0.9 points (95% CI: 0.1, 2.0; proportion mediated, 34%). No other psychological construct was a significant mediator. CONCLUSION: Improvements in perceived stress mediated improvements in disability after PT treatment compared to education. Other psychological outcomes did not mediate the effect of yoga or PT on pain or disability outcomes compared to education. J Orthop Sports Phys Ther 2022;52(7):470-483.
