ABSTRACT
BACKGROUND: While nonpharmacologic treatments are increasingly endorsed as first-line therapy for low back pain (LBP) in clinical practice guidelines, it is unclear if use of these treatments is increasing or equitable. OBJECTIVE: Examine national trends in chiropractic care and physical rehabilitation (occupational/physical therapy (OT/PT)) use among adults with LBP. DESIGN/SETTING: Serial cross-sectional analysis of the National Health Interview Survey, 2002 to 2018. PARTICIPANTS: 146,087 adults reporting LBP in prior 3 months. METHODS: We evaluated the association of survey year with chiropractic care or OT/PT use in prior 12 months. Logistic regression with multilevel linear splines was used to determine if chiropractic care or OT/PT use increased after the introduction of clinical guidelines. We also examined trends in use by age, sex, race, and ethnicity. When trends were similar over time, we present differences by these demographic characteristics as unadjusted ORs using data from all respondents. RESULTS: Between 2002 and 2018, less than one-third of adults with LBP reported use of either chiropractic care or OT/PT. Rates did not change until 2016 when uptake increased with the introduction of clinical guidelines (2016-2018 vs 2002-2015, OR = 1.15; 95% CI: 1.10-1.19). Trends did not differ significantly by sex, race, or ethnicity (p for interactions > 0.05). Racial and ethnic disparities in chiropractic care or OT/PT use were identified and persisted over time. For example, compared to non-Hispanic adults, either chiropractic care or OT/PT use was lower among Hispanic adults (combined OR = 0.62, 95% CI: 0.65-0.73). By contrast, compared to White adults, Black adults had similar OT/PT use (OR = 0.98; 95% CI: 0.94-1.03) but lower for chiropractic care use (OR = 0.50; 95% CI: 0.47-0.53). CONCLUSIONS: Although use of chiropractic care or OT/PT for LBP increased after the introduction of clinical guidelines in 2016, only about a third of US adults with LBP reported using these services between 2016 and 2018 and disparities in use have not improved.

OBJECTIVE: We evaluated whether more severe back pain phenotypes-persistent, frequent, or disabling back pain-are associated with higher mortality rate among older men. METHODS: In this secondary analysis of a prospective cohort, the Osteoporotic Fractures in Men (MrOS) study, we evaluated mortality rates by back pain phenotype among 5215 older community-dwelling men (mean age, 73 years, SD = 5.6) from 6 sites in the United States. The primary back pain measure used baseline and Year 5 back pain questionnaire data to characterize participants as having no back pain, nonpersistent back pain, infrequent persistent back pain, or frequent persistent back pain. Secondary measures of back pain from the Year 5 questionnaire included disabling back pain phenotypes. The main outcomes measured were all-cause and cause-specific death. RESULTS: After the Year 5 exam, during up to 18 years of follow-up (mean follow-up = 10.3 years), there were 3513 deaths (1218 cardiovascular, 764 cancer, 1531 other). A higher proportion of men with frequent persistent back pain versus no back pain died (78% versus 69%; sociodemographic-adjusted HR = 1.27, 95% CI = 1.11-1.45). No association was evident after further adjustment for health-related factors, such as self-reported general health and comorbid chronic health conditions (fully adjusted HR = 1.00; 95% CI = 0.86-1.15). Results were similar for cardiovascular deaths and other deaths, but we observed no association of back pain with cancer deaths. Secondary back pain measures, including back-related disability, were associated with increased mortality risk that remained statistically significant in fully adjusted models. CONCLUSION: Although frequent persistent back pain was not independently associated with risk of death in older men, additional secondary disabling back pain phenotypes were independently associated with increased mortality rate. Future investigations should evaluate whether improvements in disabling back pain affect general health and well-being or risk of death.

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.

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.

OBJECTIVE: Synthesize data regarding barriers and facilitators of adoption (ie, adoption determinants) of evidence-based occupational (OT) and physical therapy (PT) interventions within real-world practice. Whether evidence varied across disciplines, settings, and use of theoretical frameworks was also examined. DATA SOURCES: Literature published from database inception to December 9, 2022, in OVID MEDLINE, EMBASE, OVID PsycINFO, Web of Science Core Collection, Cumulative Index to Nursing and Allied Health Literature, Cochrane Library, and Google Scholar. STUDY SELECTION: Original research including: (1) stakeholder insight into adoption determinants; (2) discrete evidence-based interventions delivered/supervised by an OT and/or PT; (3) intervention recipients aged 18 or older; and (4) data regarding adoption determinants. Two reviewers independently screened and evaluated studies for inclusion, with a third resolving discrepancies. Of the 3036 articles identified, 45 articles were included. DATA EXTRACTION: Data were extracted by a primary reviewer, independently evaluated by a second reviewer, and conflicts were resolved via group consensus. DATA SYNTHESIS: A descriptive synthesis approach was used to categorize adoption determinants according to constructs from the Consolidated Framework for Implementation Research. 87% of studies were published after 2014. Many studies: described PT interventions (82%); were within the outpatient setting (44%); had data gathered after implementing the intervention (71%); and did not report use of a theoretical framework to inform data collection (62%). Lack of available resources (64%) and knowledge/beliefs about the intervention (53%) were the most common barrier and facilitator, respectively. Variability in adoption determinants was observed according to discipline, setting, and use of a theoretical framework. CONCLUSIONS: Findings suggest a recent surge of scientific investment in understanding adoption determinants for evidence-based OT and PT interventions. Such knowledge can inform efforts aimed at improving OT and PT quality, thereby enhancing patient outcomes. However, our review highlighted gaps with significant implications for the delivery of evidence-based OT and PT within real-world practice settings.

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.

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.

BACKGROUND: Poor sleep is common among adults with chronic low back pain (cLBP), but the influence of cLBP treatments, such as yoga and physical therapy (PT), on sleep quality is under studied. OBJECTIVE: Evaluate the effectiveness of yoga and PT for improving sleep quality in adults with cLBP. DESIGN: Secondary analysis of a randomized controlled trial. SETTING: Academic safety-net hospital and 7 affiliated community health centers. PARTICIPANTS: A total of 320 adults with cLBP. INTERVENTION: Twelve weekly yoga classes, 1-on-1 PT sessions, or an educational book. MAIN MEASURES: Sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI) global score (0-21) at baseline, 12 weeks, and 52 weeks. Additionally, we also evaluated how the proportion of participants who achieved a clinically meaningful improvement in sleep quality (> 3-point reduction in PSQI) at 12 weeks varied by changes in pain and physical function at 6 weeks. KEY RESULTS: Among participants (mean age = 46.0, 64% female, 82% non-white), nearly all (92%) reported poor sleep quality (PSQI > 5) at baseline. At 12 weeks, modest improvements in sleep quality were observed among the yoga (PSQI mean difference [MD] = - 1.19, 95% confidence interval [CI] - 1.82, - 0.55) and PT (PSQI MD = - 0.91, 95% CI - 1.61, - 0.20) groups. Participants who reported a ≥ 30% improvement in pain or physical function at 6 weeks, compared with those who improved < 10%, were more likely to be a sleep quality responder at 12 weeks (odds ratio [OR] = 3.51, 95% CI 1.73, 7.11 and OR = 2.16, 95% CI 1.18, 3.95, respectively). Results were similar at 52 weeks. CONCLUSION: In a sample of adults with cLBP, virtually all with poor sleep quality prior to intervention, modest but statistically significant improvements in sleep quality were observed with both yoga and PT. Irrespective of treatment, clinically important sleep improvements at the end of the intervention were associated with mid-intervention pain and physical function improvements.

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.

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.

BACKGROUND: Stressful life events, such as loss of a partner, loss of a pet or financial problems, are more common with increasing age and may impact the experience of pain. The aim of the current study is to determine the cross-sectional and prospective association between stressful life events and low back pain reporting in the Osteoporotic Fracture in Men Study, a cohort of older men aged ≥65 years. METHODS: At a study visit (March 2005-May 2006), 5149 men reported whether they had experienced a stressful life event or low back pain in the prior 12 months. Following that visit, data on low back pain patients were gathered through triannual questionnaires every 4 months for 1 year. Multivariable logistic regression analyses estimated the association of stressful life events with recent past low back pain or future low back pain. RESULTS: N = 2930, (57%) men reported at least one stressful life event. The presence of a stressful life event was associated with greater odds of any low back pain (OR = 1.42 [1.26-1.59]) and activity-limiting low back pain (OR = 1.74 [1.50-2.01]) in the same period and of any low back pain (OR = 1.56 [1.39-1.74]) and frequent low back pain (OR = 1.80 [1.55-2.08]) in the following year. CONCLUSION: In this cohort of men, the presence of stressful life events increased the likelihood of reporting past and future low back pain. SIGNIFICANCE: Stressful life events such as accident or illness to a partner are common in later life and may impact the experience of pain. We present cross-sectional and prospective data highlighting a consistent association between stressful life events and low back pain in older men. Further, there is evidence to suggest that this relationship is upregulated by an individual's living situation. This information may be used to strengthen a biopsychosocial perspective of an individual's pain experience.

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.
ABSTRACT
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 pain affects up to half of individuals taking opioid agonist therapy (OAT; i.e., methadone and buprenorphine) for opioid use disorder (OUD), and yoga-based interventions may be useful for decreasing pain-related disability. Whereas more yoga practice (i.e., higher "dosage") may improve pain-related outcomes, it can be challenging for people with chronic pain taking OAT to attend class regularly and sustain a regular personal yoga practice. Therefore, we plan to optimize a yoga-based intervention (YBI) package in order to support class attendance and personal practice, thus maximizing the yoga dose received. STUDY DESIGN: Using the Multiphase Optimization Strategy (MOST) framework, we will conduct a factorial experiment to examine four intervention components that may be added to a weekly yoga class as part of a YBI. Components include: 1) personal practice videos featuring study yoga teachers, 2) two private sessions with a yoga teacher, 3) daily text messages to inspire personal practice, and 4) monetary incentives for class attendance. The primary outcome will be minutes per week engaged in yoga (including class attendance and personal practice). We plan to enroll 192 adults with chronic pain who are taking OAT for OUD in this 2x2x2x2 factorial experiment. CONCLUSION: Results of the study will guide development of an optimized yoga-based intervention package that maximizes dosage of yoga received. The final treatment package can be tested in a multisite efficacy trial of yoga to reduce pain interference in daily functioning in people with chronic pain who are taking OAT. TRIAL REGISTRATION: Pre-registration of the study was completed on ClinicalTrials.gov (identifier: NCT04641221).

While low back pain (LBP) may persist or recur over time, few studies have evaluated the individual course of LBP over a long-term period, particularly among older adults. Based on data from the longitudinal Osteoporotic Fractures in Men (MrOS) study, we aimed to identify and describe different LBP trajectories in older men and characterize members in each trajectory group. A total of 5,976 community-dwelling men (mean age=74.2) enrolled at six US sites were analyzed. Participants self-reported LBP (yes/no) every 4 months during a maximum of 10 years. Latent class growth modelling was performed to identify unique LBP trajectory groups that explained variation in the LBP data. The association of baseline characteristics with trajectory group membership was assessed using univariable and multivariable multinominal logistic regression. A five-class solution was chosen; no/rare LBP (n=2442/40.9%), low frequency-stable LBP (n=1040/17.4%), low frequency-increasing LBP (n=719/12%), moderate frequency-decreasing LBP (n=745/12.5%) and high frequency-stable LBP (n=1030/17.2%). History of falls (OR=1.52), history of LBP (OR=6.37), higher physical impairment (OR=1.51-2.85) and worse psychological function (OR=1.41-1.62) at baseline were all associated with worse LBP trajectory groups in this sample of older men. These findings present an opportunity for targeted interventions and/or management to older men with worse or increasing LBP trajectories and associated modifiable risk factors, to reduce the impact of LBP and improve quality of life.
ABSTRACT
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.
