Identifying factors associated with physical therapy use versus non-use among injured workers with back pain in Washington State.

BACKGROUND: There is little information about predictors of physical therapy (PT) use among injured workers with back pain. The primary objective of this study is to investigate the associations between PT use and baseline factors not routinely captured in workers' compensation (WC) data. METHODS: We conducted a secondary analysis using the Washington State Workers' Compensation Disability Risk Identification Study Cohort, which combines self-reported surveys with claims data from the Washington State Department of Labor and Industries State Fund. Workers with an accepted or provisional WC claim for back injury between June 2002 and April 2004 were eligible. Baseline factors for PT use were selected from six domains (socio-demographic, pain and function, psychosocial, clinical, health behaviors, and employment-related). The outcome was a binary measure for PT use within 1 year of injury. Bivariate and multivariable logistic regression models were conducted to evaluate the associations between PT use and baseline factors. RESULTS: Among the 1370 eligible study participants, we identified 673 (49%) who received at least one PT service. Baseline factors from five of the six domains (all but health behaviors) were associated with PT use, including gender, income, pain and function measures, injury severity rating, catastrophizing, recovery expectations, fear avoidance, mental health score, body mass index, first provider seen for injury, previous injury, and several work-related factors. CONCLUSION: We identify baseline factors that are associated with PT use, which may be useful in addressing disparities in access to care for injured workers with back pain in a WC system.

Assessment of physical activity levels and back pain among poles and Portuguese in the further year of the COVID-19 pandemic - a pilot study.

BACKGROUND: The vast majority of people have experienced the problem of back pain at least once in their lives for a variety of reasons. It is well known that regular physical activity at a moderate level has a number of health benefits regardless of age or gender with positive effects on the musculoskeletal, cardiovascular, respiratory or nervous systems improving fitness levels. During the pandemic, Poland experienced one of the longest periods of school lockdown in Europe. In Portugal, this period was considerably shorter. The aim of this study was to determine the level of physical activity and back pain as well as relationship between physical activity and back pain in a group of Polish and Portuguese students in the following year the COVID-19 pandemic. METHODS: The study was conducted via the Internet among students from Poland and Portugal (398 respondents - 229 from Poland and 169 from Portugal) in October 2022. In the pilot study, the International Physical Activity Questionnaire and The Oswestry Disability Index and Neck Disability Index questionnaires were used to assess the level of back pain. RESULTS: There are no statistically significant differences in the level of physical activity and pain complaints of respondents from the two countries. At least half of the students do not report any pain complaints (median in some groups being 0). In the Portuguese men, there is a correlation between the level of physical activity and the Neck Disability Index score (p = 0.0304). CONCLUSIONS: The following year, after the pandemic COVID-19 was declared, the prevalence of back pain among students in Poland and Portugal is still significant.

Factors Associated With Diagnostic Delay in Axial Spondyloarthritis: Impact of Clinical Factors and Social Vulnerability.

OBJECTIVE: Patients with axial spondyloarthritis (axSpA) often experience significant delay between symptom onset and diagnosis for reasons that are incompletely understood. We investigated associations between demographic, medical, and socioeconomic factors and axSpA diagnostic delay. METHODS: We identified patients meeting modified New York criteria for ankylosing spondylitis (AS) or 2009 Assessment of Spondyloarthritis International Society criteria for axSpA in the Mass General Brigham health care system between December 1990 and October 2021. We determined the duration of diagnostic delay, defined as the duration of back pain symptoms reported at diagnosis, as well as disease manifestations and specialty care prior to diagnosis from the electronic health record. We obtained each patient's Social Vulnerability Index (SVI) by mapping their address to the US Centers for Disease Control SVI Atlas. We examined associations among disease manifestations, SVI, and diagnostic delay using ordinal logistic regression. RESULTS: Among 554 patients with axSpA who had a median diagnostic delay of 3.8 years (interquartile range 1.1-10), peripheral arthritis (odds ratio [OR] 0.65, 95% confidence interval [CI] 0.45-0.93) and older age at symptom onset (OR 0.83, 95% CI 0.78-0.88 per five years) were associated with shorter delay. AS at diagnosis (OR 1.85, 95% CI 1.30-2.63), a history of uveitis prior to diagnosis (OR 2.77, 95% CI 1.73-4.52), and higher social vulnerability (defined as national SVI 80th to 99th percentiles; OR 1.99, 95% CI 1.06-3.84) were associated with longer diagnostic delay. CONCLUSION: Older age at back pain onset and peripheral arthritis were associated with shorter delay, whereas uveitis was associated with longer diagnostic delay. Patients with higher socioeconomic vulnerability had longer diagnostic delay independent of clinical factors.

Effects of chiropractic use on medical healthcare utilization and costs in adults with back pain in Ontario, Canada from 2003 to 2018: a population-based cohort study.

BACKGROUND: Adults with back pain commonly consult chiropractors, but the impact of chiropractic use on medical utilization and costs within the Canadian health system is unclear. We assessed the association between chiropractic utilization and subsequent medical healthcare utilization and costs in a population-based cohort of Ontario adults with back pain. METHODS: We conducted a population-based cohort study that included Ontario adult respondents of the Canadian Community Health Survey (CCHS) with back pain from 2003 to 2010 (n = 29,475), followed up to 2018. The CCHS data were individually-linked to individual-level health administrative data up to 2018. Chiropractic utilization was self-reported consultation with a chiropractor in the past 12 months. We propensity score-matched adults with and without chiropractic utilization, accounting for confounders. We evaluated back pain-specific and all-cause medical utilization and costs at 1- and 5-year follow-up using negative binomial and linear (log-transformed) regression, respectively. We assessed whether sex and prior specialist consultation in the past 12 months were effect modifiers of the association. RESULTS: There were 6972 matched pairs of CCHS respondents with and without chiropractic utilization. Women with chiropractic utilization had 0.8 times lower rate of cause-specific medical visits at follow-up than those without chiropractic utilization (RR5years = 0.82, 95% CI 0.68-1.00); this association was not found in men (RR5years = 0.96, 95% CI 0.73-1.24). There were no associations between chiropractic utilization and all-cause physician visits, all-cause emergency department visits, all-cause hospitalizations, or costs. Effect modification of the association between chiropractic utilization and cause-specific utilization by prior specialist consultation was found at 1-year but not 5-year follow-up; cause-specific utilization at 1 year was lower in adults without prior specialist consultation only (RR1year = 0.74, 95% CI 0.57-0.97). CONCLUSIONS: Among adults with back pain, chiropractic use is associated with lower rates of back pain-specific utilization in women but not men over a 5-year follow-up period. Findings have implications for guiding allied healthcare delivery in the Ontario health system.

Demographics of and Costs to Users of Chiropractic Services in the United States with Neck or Back Pain not Meeting Guideline-Based Minimum Treatment Frequency Thresholds.

Context: Acceptance of chiropractic services as an effective therapy for neck or back pain has been well established with randomized controlled trials (RCTs); however, there have been limited observations made on the treatment frequency patterns seen in the real world. Objective: The purpose of this study is to identify chiropractic users with neck or back pain who did not meet recommended treatment frequency guidelines and examine their demographics and chiropractic costs. Design: In this cross-sectional retrospective study, the nationally representative 2017 Medical Expenditure Panel Survey database was used. Setting: This study used nationally representative US survey data. Participants: Inclusion criteria were adults aged 18 years and older with a diagnosis of neck or back pain with one or more chiropractic visits in 2017. Outcomes Measures: Chiropractic utilization was categorized as concordant or discordant with treatment frequency guidelines; concordant was defined as 5 or more visits to a chiropractor within any 2-month time frame or at least 12 total visits during the year. Discordant was defined as circumstances not meeting concordant criteria. The groups were compared by demographics including age, sex, race, region, years of education, health insurance coverage, employment status, family income, presence of headache diagnosis, Charlson Comorbidity Index score and the presence of any limitation of physical function. Comparisons were made between the two groups using Chi-squared tests. Logistic regression was used to adjust for covariates. Results: There were 159 and 310 adults classified as concordant and discordant, respectively (weighted total: 1 849 108 [31.44%] and 4 032 541 [68.56%], with significantly different mean chiropractic costs of $2555 and $434, respectively. Significant independent predictors of discordant chiropractic utilization were race, years of education, family income and the presence of any limitation of physical function. Conclusions: Most chiropractic users with diagnosed neck or back pain were considered discordant with treatment frequency guidelines, which may indicate inefficiencies in treatment and inefficient use of healthcare resources.

Inferior Clinical Outcomes for Patients with Medicaid Insurance After Surgery for Degenerative Lumbar Spondylolisthesis: A Prospective Registry Analysis of 608 Patients.

BACKGROUND: It remains unclear how type of insurance coverage affects long-term, spine-specific patient-reported outcomes (PROs). This study sought to elucidate the impact of insurance on clinical outcomes after lumbar spondylolisthesis surgery. METHODS: The prospective Quality Outcomes Database registry was queried for patients with grade 1 degenerative lumbar spondylolisthesis who underwent single-segment surgery. Twenty-four-month PROs were compared and included Oswestry Disability Index, Numeric Rating Scale (NRS) back pain, NRS leg pain, EuroQol-5D, and North American Spine Society Satisfaction. RESULTS: A total of 608 patients undergoing surgery for grade 1 degenerative lumbar spondylolisthesis (mean age, 62.5 ± 11.5 years and 59.2% women) were selected. Insurance types included private insurance (n = 319; 52.5%), Medicare (n = 235; 38.7%), Medicaid (n = 36; 5.9%), and Veterans Affairs (VA)/government (n = 17; 2.8%). One patient (0.2%) was uninsured and was removed from the analyses. Regardless of insurance status, compared to baseline, all 4 cohorts improved significantly regarding ODI, NRS-BP, NRS-LP, and EQ-5D scores (P < 0.001). In adjusted multivariable analyses, compared with patients with private insurance, Medicaid was associated with worse 24-month postoperative Oswestry Disability Index (ß = 10.2; 95% confidence interval [CI], 3.9-16.5; P = 0.002) and NRS leg pain (ß =1.3; 95% CI, 0.3-2.4; P = 0.02). Medicaid was associated with worse EuroQol-5D scores compared with private insurance (ß = -0.07; 95% CI -0.01 to -0.14; P = 0.03), but not compared with Medicare and VA/government insurance (P > 0.05). Medicaid was associated with lower odds of reaching ODI minimal clinically important difference (odds ratio, 0.2; 95% CI, 0.03-0.7; P = 0.02) compared with VA/government insurance. NRS back pain and North American Spine Society satisfaction did not differ by insurance coverage (P > 0.05). CONCLUSIONS: Despite adjusting for potential confounding variables, Medicaid coverage was independently associated with worse 24-month PROs after lumbar spondylolisthesis surgery compared with other payer types. Although all improved postoperatively, those with Medicaid coverage had relatively inferior improvements.

A clinical tool to identify older women with back pain at high risk of osteoporotic vertebral fractures (Vfrac): a population-based cohort study with exploratory economic evaluation.

BACKGROUND: osteoporotic vertebral fractures (OVFs) identify people at high risk of future fractures, but despite this, less than a third come to clinical attention. The objective of this study was to develop a clinical tool to aid health care professionals decide which older women with back pain should have a spinal radiograph. METHODS: a population-based cohort of 1,635 women aged 65+ years with self-reported back pain in the previous 4 months were recruited from primary care. Exposure data were collected through self-completion questionnaires and physical examination, including descriptions of back pain and traditional risk factors for osteoporosis. Outcome was the presence/absence of OVFs on spinal radiographs. Logistic regression models identified independent predictors of OVFs, with the area under the (receiver operating) curve calculated for the final model, and a cut-point was identified. RESULTS: mean age was 73.9 years and 209 (12.8%) had OVFs. The final Vfrac model comprised 15 predictors of OVF, with an AUC of 0.802 (95% CI: 0.764-0.840). Sensitivity was 72.4% and specificity was 72.9%. Vfrac identified 93% of those with more than one OVF and two-thirds of those with one OVF. Performance was enhanced by inclusion of self-reported back pain descriptors, removal of which reduced AUC to 0.742 (95% CI: 0.696-0.788) and sensitivity to 66.5%. Health economic modelling to support a future trial was favourable. CONCLUSIONS: the Vfrac clinical tool appears to be valid and is improved by the addition of self-reported back pain symptoms. The tool now requires testing to establish real-world clinical and cost-effectiveness.

Joint effects of back pain and mental health conditions on healthcare utilization and costs in Ontario, Canada: a population-based cohort study.

ABSTRACT: We assessed the joint effects of back pain and mental health conditions on healthcare utilization and costs in a population-based sample of adults in Ontario. We included Ontario adult respondents of the Canadian Community Health Survey between 2003 and 2012, followed up to 2018 by linking survey data to administrative databases. Joint exposures were self-reported back pain and mental health conditions (fair/poor mental health, mood, and anxiety disorder). We built negative binomial, modified Poisson and linear (log-transformed) models to assess joint effects (effects of 2 exposures in combination) of comorbid back pain and mental health condition on healthcare utilization, opioid prescription, and costs. The models were adjusted for sociodemographic, health-related, and behavioural factors. We evaluated positive additive and multiplicative interaction (synergism) between back pain and mental health conditions with relative excess risk due to interaction (RERI) and ratio of rate ratios (RRs). The cohort (n = 147,486) had a mean age of 46 years (SD = 17), and 51% were female. We found positive additive and multiplicative interaction between back pain and fair/poor mental health (RERI = 0.40; ratio of RR = 1.12) and mood disorder (RERI = 0.41; ratio of RR = 1.04) but not anxiety for back pain-specific utilization. For opioid prescription, we found positive additive and multiplicative interaction between back pain and fair/poor mental health (RERI = 2.71; ratio of risk ratio = 3.20) and anxiety (RERI = 1.60; ratio of risk ratio = 1.80) and positive additive interaction with mood disorder (RERI = 0.74). There was no evidence of synergism for all-cause utilization or costs. Combined effects of back pain and mental health conditions on back pain-specific utilization or opioid prescription were greater than expected, with evidence of synergism. Health services targeting back pain and mental health conditions together may provide greater improvements in outcomes.

Subjective social status moderates back pain and mental health in older men.

OBJECTIVES: Back pain and poor mental health are interrelated issues in older men. Evidence suggests that socioeconomic status moderates this relationship, but less is known about the role of subjective social status (SSS). This study examined if the association between back pain and mental health is moderated by SSS. METHOD: We used a sample of community-dwelling older men (≥65 years) from the Osteoporotic Fractures in Men Study (N = 5994). Participants self-reported their back pain severity and frequency over the past 12 months. SSS was assessed with the MacArthur Scale of SSS. Mental health was assessed with the SF-12 Mental Component Summary (MCS). RESULTS: Severe back pain was associated with lower SF-12 MCS scores (p = .03). Back pain frequency was not associated with SF-12 MCS scores. SSS moderated the back pain and mental health relationship. Among men with higher national or community SSS, the association between back pain severity and SF-12 MCS scores was not significant. However, among men with lower national or community SSS, more severe back pain was associated with lower SF-12 MCS scores (p's < .001). Among those with lower national or community SSS, greater back pain frequency was also associated with lower SF-12 MCS scores (p's < .05). CONCLUSION: Where one ranks oneself within their nation or community matters for the back pain and mental health relationship. Higher SSS may be a psychosocial resource that buffers the negative associations of severe and frequent back pain on mental health in older men.

Increased Use of Complementary and Alternative Therapies for Back Pain Following Statewide Medicaid Coverage Changes in Oregon.

BACKGROUND: In 2016, Oregon introduced a policy to improve back pain treatment among Medicaid enrollees by expanding benefits for evidence-based complementary and alternative medical (CAM) services and establishing opioid prescribing restrictions. OBJECTIVE: To examine changes in CAM utilization following the policy and variations in utilization across patient populations. DESIGN: A retrospective study of Oregon Medicaid claims data, examining CAM therapy utilization by back pain patients pre- vs post-policy. We used an interrupted time series analysis to evaluate changes in CAM use and examined the association between patient characteristics and CAM use post-policy using linear regression models. PARTICIPANTS: Adult Medicaid patients with back pain. INTERVENTION: The Oregon Medicaid back pain policy, administered through Coordinated Care Organizations (CCOs). MAIN MEASURES: Use of CAM services. KEY RESULTS: Use of any CAM service increased from 7.9% (95% CI 7.6-8.2%) prior to the policy to 30.9% (95% CI 30.4-31.3%) after the policy. Acupuncture increased from 0.3 to 5.6%, chiropractic from 0.3 to 11.1%, massage from 1.6 to 14.8%, PT/OT from 6.0 to 17.7%, and osteopathic from 1.4 to 1.9%. Interrupted time series showed an overall increase in proportion of back pain patients who used CAM service following the policy. Among those who accessed CAM, the policy did not appear to increase the number of services used. In the post period, CAM services were accessed more often by female and older enrollees and urban populations. Black, American Indian/Alaska Native, and Hispanic enrollees were less likely to access CAM services; for Black enrollees, this was true for all types of services. CONCLUSIONS: CAM service utilization increased among back pain patients following implementation of Oregon's policy. There was significant heterogeneity in uptake across service types, CCOs, and patient subgroups. Policymakers should consider implementation factors that might limit impact and perpetuate health disparities.

A Systematic Review of the Incidence, Prevalence, Costs, and Activity and Work Limitations of Amputation, Osteoarthritis, Rheumatoid Arthritis, Back Pain, Multiple Sclerosis, Spinal Cord Injury, Stroke, and Traumatic Brain Injury in the United States: A 2019 Update.

OBJECTIVES: To present recent evidence on the prevalence, incidence, costs, activity limitations, and work limitations of common conditions requiring rehabilitation. DATA SOURCES: Medline (PubMed), SCOPUS, Web of Science, and the gray literature were searched for relevant articles about amputation, osteoarthritis, rheumatoid arthritis, back pain, multiple sclerosis, spinal cord injury, stroke, and traumatic brain injury. STUDY SELECTION: Relevant articles (N=106) were included. DATA EXTRACTION: Two investigators independently reviewed articles and selected relevant articles for inclusion. Quality grading was performed using the Methodological Evaluation of Observational Research Checklist and Newcastle-Ottawa Quality Assessment Form. DATA SYNTHESIS: The prevalence of back pain in the past 3 months was 33.9% among community-dwelling adults, and patients with back pain contribute $365 billion in all-cause medical costs. Osteoarthritis is the next most prevalent condition (approximately 10.4%), and patients with this condition contribute $460 billion in all-cause medical costs. These 2 conditions are the most prevalent and costly (medically) of the illnesses explored in this study. Stroke follows these conditions in both prevalence (2.5%-3.7%) and medical costs ($28 billion). Other conditions may have a lower prevalence but are associated with relatively higher per capita effects. CONCLUSIONS: Consistent with previous findings, back pain and osteoarthritis are the most prevalent conditions with high aggregate medical costs. By contrast, other conditions have a lower prevalence or cost but relatively higher per capita costs and effects on activity and work. The data are extremely heterogeneous, which makes anything beyond broad comparisons challenging. Additional information is needed to determine the relative impact of each condition.

Axial and peripheral spondyloarthritis: does psoriasis influence the clinical expression and disease burden? Data from REGISPONSER registry.

OBJECTIVE: To evaluate whether the presence of psoriasis influences the clinical expression, disease activity and disease burden in both axial and peripheral phenotypes of spondyloarthritis (SpA). METHODS: Patients from the Spanish REGISPONSER registry classified as having SpA according to the ESSG criteria were included. Patients were classified as psoriatic or non-psoriatic depending on the presence of cutaneous or nail psoriasis; thereafter, they were classified as having either axial [presence of radiographic sacroiliitis OR inflammatory back pain (IBP)] or peripheral phenotype (absence of radiographic sacroiliitis AND absence of IBP AND presence of peripheral involvement). Pair-wise univariate and multivariate analyses among the four groups (psoriatic/non-psoriatic axial phenotypes and psoriatic/non-psoriatic peripheral phenotypes) were performed with adjustment for treatment intake. RESULTS: A total of 2296 patients were included in the analysis. Among patients with axial phenotype, psoriasis was independently associated (P < 0.05) with HLA-B27+ [odds ratio (OR) 0.27], uveitis (OR 0.46), synovitis (ever) (OR 2.59), dactylitis (OR 2.78) and the use of conventional synthetic DMARDs (csDMARDs) (OR 1.47) in comparison with non-psoriatic patients. Among patients with peripheral phenotype and adjusting for csDMARD intake, psoriasis was independently associated with higher age at disease onset (OR 1.05), HLA-B27+ (OR 0.14) and heel enthesitis (OR 0.22). Higher scores for patient-reported outcomes and greater use of treatment at the time of the study visit were observed in psoriatic patients with either axial or peripheral phenotype. CONCLUSION: These findings suggest that, among all patients with SpA, psoriasis is associated with differences in clinical expression of SpA, a greater disease burden and increased use of drugs.

Bone fractures in patients using tapentadol or oxycodone: an exploratory US claims database study.

Aim: To explore fracture outcomes with tapentadol or oxycodone, two opioids with differing mechanisms of action. Materials & methods: Retrospective cohort pilot study, using MarketScan® Commercial and Medicare Supplemental claims databases, on patients with postoperative pain, back pain, or osteoarthritis and ≥1 claim for tapentadol (n = 16,457), oxycodone (n = 1,356,920), or both (n = 15,893) between June 2009 and December 2015. Results: During 266,826 and 9,007,889 days of tapentadol and oxycodone treatment, patients evidenced 1080 and 72,275 fractures, respectively. Fracture rates per treatment-year were 1.512 for tapentadol and 3.013 for oxycodone. Conclusion: Examination of administrative claims has inherent limitations, but this exploratory analysis indicates a lower fracture rate with tapentadol than oxycodone in the analyzed dataset, which needs confirmation by further clinical trials.

The Effect of Including Benchmark Prevalence Data of Common Imaging Findings in Spine Image Reports on Health Care Utilization Among Adults Undergoing Spine Imaging: A Stepped-Wedge Randomized Clinical Trial.

Importance: Lumbar spine imaging frequently reveals findings that may seem alarming but are likely unrelated to pain. Prior work has suggested that inserting data on the prevalence of imaging findings among asymptomatic individuals into spine imaging reports may reduce unnecessary subsequent interventions. Objective: To evaluate the impact of including benchmark prevalence data in routine spinal imaging reports on subsequent spine-related health care utilization and opioid prescriptions. Design, Setting, and Participants: This stepped-wedge, pragmatic randomized clinical trial included 250 401 adult participants receiving care from 98 primary care clinics at 4 large health systems in the United States. Participants had imaging of their backs between October 2013 and September 2016 without having had spine imaging in the prior year. Data analysis was conducted from November 2018 to October 2019. Interventions: Either standard lumbar spine imaging reports (control group) or reports containing age-appropriate prevalence data for common imaging findings in individuals without back pain (intervention group). Main Outcomes and Measures: Health care utilization was measured in spine-related relative value units (RVUs) within 365 days of index imaging. The number of subsequent opioid prescriptions written by a primary care clinician was a secondary outcome, and prespecified subgroup analyses examined results by imaging modality. Results: We enrolled 250 401 participants (of whom 238 886 [95.4%] met eligibility for this analysis, with 137 373 [57.5%] women and 105 497 [44.2%] aged >60 years) from 3278 primary care clinicians. A total of 117 455 patients (49.2%) were randomized to the control group, and 121 431 patients (50.8%) were randomized to the intervention group. There was no significant difference in cumulative spine-related RVUs comparing intervention and control conditions through 365 days. The adjusted median (interquartile range) RVU for the control group was 3.56 (2.71-5.12) compared with 3.53 (2.68-5.08) for the intervention group (difference, -0.7%; 95% CI, -2.9% to 1.5%; P = .54). Rates of subsequent RVUs did not differ between groups by specific clinical findings in the report but did differ by type of index imaging (eg, computed tomography: difference, -29.3%; 95% CI, -42.1% to -13.5%; magnetic resonance imaging: difference, -3.4%; 95% CI, -8.3% to 1.8%). We observed a small but significant decrease in the likelihood of opioid prescribing from a study clinician within 1 year of the intervention (odds ratio, 0.95; 95% CI, 0.91 to 1.00; P = .04). Conclusions and Relevance: In this study, inserting benchmark prevalence information in lumbar spine imaging reports did not decrease subsequent spine-related RVUs but did reduce subsequent opioid prescriptions. The intervention text is simple, inexpensive, and easily implemented. Trial Registration: ClinicalTrials.gov Identifier: NCT02015455.

Effectiveness of a theory-based back care intervention on spine-related behavior among pupils: a school-based randomised controlled trial (T-Bak study).

BACKGROUND: Children's health and welfare have a special place in research and policy in many countries. One of the most important concerns is the increasing rate of backache in children due to many of behavioral risk factors. The aim of this study was to evaluate the effectiveness of an educational program on promoting back-related behavior as well as knowledge, skills, beliefs, and self-efficacy among fifth grade girls. METHODS: The theory-based back care (T-Bak) study was a school-based randomised controlled trial (RCT) that assessed the effectiveness of developing a back care training program based on the social cognitive theory (SCT). A total of 104 schoolchildren aged 11 ± 1.0 years were assigned to intervention (n = 52) and control (n = 52) groups. The intervention group received six sessions training on proper lifting and carrying techniques, having proper posture during daily activities, and correct backpack wearing techniques with a 1-week interval while the control group received nothing. Then, the two groups were assessed for knowledge, skills, self-efficacy, beliefs, and behavior at four points in time: baseline, immediate, three and six-months post-intervention. The changes of the outcomes investigated using univariate repeated measures analysis of variance. Partial eta squared measure (ηp2) was used to calculate effect sizes. RESULTS: A positive change was found for the intervention group back-related behavior from baseline to immediate post-intervention and follow-ups (F = 78.865, p < 0.001, ηp2 = 0.22). Overall there were 36.4% improvement for knowledge (ηp2 = 0.21), 53.2% for the skills (ηp2 = 0.25), 19.5% for the self-efficacy (ηp2 = 0.11), and 25.6% for the beliefs (ηp2 = 0.14) scores from baseline to 6 months' follow-up assessments among the intervention group (p < 0.001). The results also showed a significant interaction effect between group and time. CONCLUSION: The T-Bak intervention was effective in improving back-related behavior in pupils. It is now available and could be evaluated further in back-care related studies.

Self-Efficacy and Multisite Pain Predictors among Economically Disadvantaged Women with Back Pain.

BACKGROUND: Chronic low back pain (CLBP) prevalence is higher among women and those with low socioeconomic status. Without adequate self-efficacy and subsequent self-management, patients gradually develop chronic multisite pain after one year of having CLBP alone. AIM: This study investigated the predictors of self-efficacy and multisite pain among adult, economically disadvantaged women, where pain prevalence is higher. DESIGN: Cross-sectional, descriptive study. SETTING: Pain management center. SUBJECTS: Participants (n = 50) with primary diagnosis of chronic low back pain. METHODS: After Institutional Review Board approval, data collection was conducted using valid and reliable instruments measuring several variables. Controlling for age and race, multiple linear regression was used for analyses. RESULTS AND CONCLUSIONS: For all predictors of self-efficacy, a significant regression equation was identified (p < .01) with R2 of .413 and variance of .643. Pain catastrophizing was a significant individual predictor (p < .05). A significant regression equation was also found for all predictors of multisite pain (p < .001) with R2 of .528 and variance of .726. Individual predictors (p < .05) were age, physical function, and numbers of pain treatments and chronic medical conditions. Study findings suggest that significant predictors can be key to advancing pain research, education, practice, and healthcare policy toward improving pain management. Particularly among this population, pain catastrophizing needs to be targeted in pain management. To minimize development of multisite pain, further investigation of identified predictors including number of chronic medical conditions and pain treatments received are necessary. Multimodal, but targeted approaches addressing these predictors are recommended, instead of costly, indiscriminate multimodal therapy. Targeted interventions can help reduce pain care disparities among socioeconomically disadvantaged women, identify high risk groups for prompt intervention, facilitate better pain response to treatments, and minimize further disability.

The Epidemiology of Back Pain in American Children and Adolescents.

STUDY DESIGN: Cross-sectional survey. OBJECTIVE: To determine the prevalence of back pain in American children and adolescents, with a focus on anatomic region, duration, severity, and treatment patterns, and to investigate for any predictive variables. SUMMARY OF BACKGROUND DATA: No study has examined the prevalence of back pain in American children and adolescents in the last 15 years. Because the prevalence of back pain varies greatly by country and year of investigation, previous studies are not generalizable. METHODS: A United States epidemiologic cross-sectional survey-based investigation was performed in children and adolescents ages 10 and 18 years old, equally split by age and sex, and representing census-weighted distributions of state of residence, race/ethnicity, and health insurance status. Prevalence of back pain was evaluated and described. RESULTS: In total, 1236 (33.7%) participants reported experiencing back pain within the last year and 325 (8.9%) reported severe back pain within the last year. Prevalence of back pain increased with age and was significantly more common in females, P < 0.001 for both. Treatment for back pain was sought by 505 (40.9%) of the participants with pain, of which physical therapy was the most common. Invasive procedural treatment (e.g., injections, surgery) were rare and comprised only 61 (1.6%) of study participants. In addition, government insurance and lack of insurance coverage was associated with low treatment seeking behavior compared to private insurance users (P = 0.010 and P = 0.006, respectively). CONCLUSION: Despite how commonly it presents, the majority of young patients with back pain do not report procedural treatment such as injections or surgery. However, because many American children and adolescents seek treatment, future research on the etiology, treatment, and prevention of back pain in children and adolescents is essential to reducing a common and financially demanding problem.

Homeless patients tend to have greater psychiatric needs when presenting to the emergency department.

INTRODUCTION: Homeless patients tend to visit Emergency Departments (EDs) more frequently than the non-homeless population. The goal of this study was to assess differences in chief complaint, medical conditions, and disposition between homeless patients compared to non-homeless patients presenting to an urban ED. METHODS: This was a retrospective cohort of homeless patients ages ≥18 years compared to non-homeless controls from January 1, 2017 to December 31, 2017. Exclusion criteria were as follows: direct admission to hospital floor, repeat visits, or leaving without being seen. The primary endpoint of this study was to assess differences in chief complaint of homeless versus non-homeless patients upon presentation to the ED. Our secondary endpoints included differences in ED utilization between the two groups, in terms of length of stay, ambulance use, diagnosis, and disposition. RESULTS: Homeless patients were more likely present to the ED for a psychiatric evaluation (homeless group 34% vs. non-homeless group 4%, p < 0.01) and have a history of a psychiatric diagnosis (56% vs. 10%, p < 0.01) compared to non-homeless controls. Homeless patients also tended to require more ambulance transport (46% vs. 16%, p < 0.01). More homeless patients were transferred to a psychiatric facility (40% vs. 1%, p < 0.01), while the majority of non-homeless patients were discharged home (50% vs. 93%, p < 0.01). CONCLUSION: This study found that homeless patients had a significantly higher association with psychiatric diagnoses and greater ED utilization than non-homeless. This suggests the importance of increased access to consistent psychiatric care and follow up within the homeless population.

Emergency Department Visits After Posterior Spinal Fusion for Adolescent Idiopathic Scoliosis.

BACKGROUND: The incidence of emergency department (ED) visits after posterior spinal fusion (PSF) in adolescent idiopathic scoliosis (AIS) patients is not well known. We hypothesize that the majority of ED visits are related to constipation and pain issues, and are not for serious complications. METHODS: Using a private insurance claims database, we identified AIS patients aged 10 to 21 years who underwent PSF from 2010 to 2015. Patients were excluded for diagnoses of neuromuscular or syndromic scoliosis. ED visits that occurred within the 6-month postoperative period were identified. The diagnoses present at these visits were pooled and analyzed, in addition to insurance payments associated with these visits. Significance was set at P=0.05. RESULTS: A total of 5934 patients met inclusion criteria. Mean age was 14.4±2.2 years, and 75% of the patients were girls. A total of 577 (9.7%) patients had at least 1 ED visit in the 6-month postoperative period, whereas 92 (1.6%) had 2 ED visits and 19 (0.3%) had 3 or more ED visits. The median time to ED visits was 33 days after surgery. Independent risk factors for ED visits were: older age, and greater levels fused (P<0.05). The top 5 most common reasons for ED visits were: pain/back or musculoskeletal, constipation/GI issues, asthma/ respiratory issues, upper respiratory infection, and dehydration. Rates of ED visits were similar among the US geographic regions. Patients who had an ED visit had significantly higher total 6-month health care payments than those who did not (P<0.001). CONCLUSIONS: Approximately 10% of the patients had ≥1 ED visit in the 6-month period after PSF for AIS. A majority of the diagnoses at these ED visits were outpatient medical issues. LEVEL OF EVIDENCE: Level III.

Evaluation and management of paediatric and adolescent back pain: Epidemiology, presentation, investigation, and clinical management: A narrative review.

This narrative review will summarise a clinical approach to the investigation of back pain in children and adolescent patients, including a discussion of the epidemiology, presentation, investigation and clinical management of back pain in children and adolescents. This will assist the prompt and accurate diagnosis of spinal disorders that require significant medical intervention. Existing evidence suggests a relatively high incidence of non-specific back pain among young people; 27-48% of presentations of back pain in children and adolescents are attributed to non-specific back pain. Low back pain among schoolchildren is often linked to psychosocial factors and only occasionally requires medical attention, as pain is benign and self-limiting. Nonetheless, those young patients who seek medical assistance exhibit a higher incidence of organic conditions underlying the major symptom of spinal pain. A cautious and comprehensive strategy - including a detailed history, examination, radiographic imaging and diagnostic laboratory studies - should be employed, which must be accurate, reliable, consistent and reproducible in identifying spinal pathologies. A specific diagnosis can be reached in 52-73% of the cases. For cases in which a specific diagnosis cannot be made, re-evaluation after a period of observation is recommended. At this later stage, minor symptoms unrelated to underlying pathology will resolve spontaneously, whereas serious pathologies will advance and become easily identified.
