Abstract
BACKGROUND Increasingly, integrated healthcare systems such as the United States Veterans Health Administration (VHA) are employing chiropractors. However, little is known about chiropractor employee clinical productivity which may be important for resource planning and monitoring care delivery. With its history of delivering chiropractic care and its enterprise-level assessment metrics, the VHA is an ideal setting to study a chiropractic workforce. We aim to assess characteristics of chiropractors employed by the VHA and explore associations between these characteristics and clinical productivity. METHODS This was a cross-sectional and serial analyses of VHA administrative data. Characteristics of the chiropractor workforce were evaluated from fiscal year (FY) 2016 to FY2019. Productivity was calculated using the VHA productivity measure, the quotient of an individual's total work relative value units (wRVUs) per FY divided by the direct clinical full-time equivalent (FTE) worked. A multivariable regression model was used to analyze the association between productivity and characteristics of the chiropractor and VHA facility. RESULTS From FY2016 to FY2019, the number of chiropractor employees increased from 102 to 167. In FY2019, the typical chiropractor employee was male, white, and 45.9 years old with 5.2 years of VHA experience. In FY2019, the VHA chiropractor workforce was 25.1% female, 79% white, and 20.4% Veteran. The productivity measure of a chiropractor was 3040 in FY2019. A higher facility complexity measure, presence of 3 chiropractor employees at a facility, and older age of the providers were the only characteristics studied that had a significant impact on productivity after adjusting for other covariates. CONCLUSION Provider characteristics and productivity metrics of the VHA chiropractor employee workforce are presented. The productivity measure provides an initial benchmarking that may be relevant to future modeling of chiropractor personnel in VHA and other healthcare systems.

Joint effects of back pain and mental health conditions on health care utilization and costs in Ontario, Canada: A population-based cohort study. Pain 2022; 163:1892-1904. [PMID: 35082249 DOI: 10.1097/j.pain.0000000000002587] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2021] [Accepted: 01/05/2022] [Indexed: 11/26/2022]
Abstract
ABSTRACT We assessed the joint effects of back pain and mental health conditions on healthcare utilization and costs in a population-based sample of Ontario adults. We included Ontario adult respondents of Canadian Community Health Survey between 2003-2012, followed 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, anxiety disorder). We built negative binomial, modified Poisson, and linear (log-transformed) models to assess joint effects (effects of two exposures in combination) of comorbid back pain and mental health condition on healthcare utilization, opioid prescription, and costs, adjusting 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 (RR). 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;RR=1.12) and mood disorder (RERI=0.41;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;RR=3.20) and anxiety (RERI=1.60;RR=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.

Abstract
OBJECTIVE To examine the relationships between nonpharmacological treatment (NPT) utilization and opioid prescriptions and doses and whether these relationships vary according to the type of NPT service received. DATA SOURCE Secondary data from the US Military Health System, nationwide. STUDY DESIGN Patterns of NPT utilization and opioid prescriptions were analyzed over the 23 months after initial pain treatment (index visit). Regression models were used to examine the relationship between opioid prescription use in a given month and NPT service utilization in the three preceding months, using person fixed effects to control for time-invariant patient characteristics, as well as time fixed effects. Analyses were stratified by whether the patient filled an opioid prescription in the first 30 days post index visit. DATA EXTRACTION METHODS Administrative data on health care utilization were extracted from the US Military Health System Data Repository for Army service members who returned from deployments in Afghanistan and Iraq that ended in fiscal years 2008 to 2014 and had at least one outpatient visit with a primary diagnosis of musculoskeletal pain in the subsequent year. PRINCIPAL FINDINGS Utilization of any NPT service in the past 3 months was positively associated with filling an opioid prescription in the given month, regardless of whether the patient was initially prescribed opioids (percentage point difference [PP] =2.87, P < 0.01) or not (PP = 0.83, P < 0.01). However, for those not initially prescribed opioids, use of any NPT service in the past 3 months was negatively associated with mean daily opioid dose in the given month (morphine milligram equivalent dose = -0.4017, P < 0.01). For those initially prescribed opioids, NPT was not associated with opioid dose. CONCLUSIONS NPT only reduced the prescription opioid daily dose for some patients, whereas the probability of receiving an opioid prescription was positively associated with NPT. Future research should assess whether recent system-level policies and program changes influence referral and opioid prescribing patterns.

[PMID: 33879351 DOI: 10.1016/j.jmpt.2021.01.003] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2020] [Revised: 08/20/2020] [Accepted: 01/20/2021] [Indexed: 01/14/2023]
Abstract
OBJECTIVE The purpose of this study was to describe changes in opioid-therapy prescription rates after a family medicine practice included on-site chiropractic services. METHODS The study design was a retrospective analysis of opioid prescription data. The database included opioid prescriptions written for patients seeking care at the family medicine practice from April 2015 to September 2018. In June 2016, the practice reviewed and changed its opioid medication practices. In April 2017, the practice included on-site chiropractic services. Opiod-therapy use was defined as the average rate of opioid prescriptions over all medical providers at the practice. RESULTS There was a significant decrease of 22% in the average monthly rate of opioid prescriptions after the inclusion of chiropractic services (F1,40 = 10.69; P < .05). There was a significant decrease of 32% in the prescribing rate of schedule II opioids after the inclusion of chiropractic services (F2,80 = 6.07 for the Group × Schedule interaction; P < .05). The likelihood of writing schedule II opioid prescriptions decreased by 27% after the inclusion of chiropractic services (odds ratio, 0.73; 95% confidence interval, 0.59-0.90). Changes in opioid medication practices by the medical providers included prescribing a schedule III or IV opioid rather than a schedule II opioid (F6,76 = 29.81; P < .05) and a 30% decrease in the daily doses of opioid prescriptions (odds ratio, 0.70; 95% confidence interval, 0.50-0.98). CONCLUSION This study demonstrates that there were decreases in opioid-therapy prescribing rates after a family medicine practice included on-site chiropractic services. This suggests that inclusion of chiropractic services may have had a positive effect on prescribing behaviors of medical physicians, as they may have been able to offer their patients additional nonpharmaceutical options for pain management.

Abstract
OBJECTIVE To investigate the current evidence to determine if there is an association between chiropractic use and opioid receipt. DESIGN Systematic review and meta-analysis. METHODS The protocol for this review was registered on PROSPERO (CRD42018095128). The MEDLINE, PubMed, EMBASE, AMED, CINAHL, and Web of Science databases were searched for relevant articles from database inception through April 18, 2018. Controlled studies, cohort studies, and case-control studies including adults with noncancer pain were eligible for inclusion. Studies reporting opioid receipt for both subjects who used chiropractic care and nonusers were included. Data extraction and risk of bias assessment were completed independently by pairs of reviewers. Meta-analysis was performed and presented as an odds ratio with 95% confidence interval. RESULTS In all, 874 articles were identified. After detailed selection, 26 articles were reviewed in full, and six met the inclusion criteria. Five studies focused on back pain and one on neck pain. The prevalence of chiropractic care among patients with spinal pain varied between 11.3% and 51.3%. The proportion of patients receiving an opioid prescription was lower for chiropractic users (range = 12.3-57.6%) than nonusers (range = 31.2-65.9%). In a random-effects analysis, chiropractic users had a 64% lower odds of receiving an opioid prescription than nonusers (odds ratio = 0.36, 95% confidence interval = 0.30-0.43, P < 0.001, I2 = 92.8%). CONCLUSIONS This review demonstrated an inverse association between chiropractic use and opioid receipt among patients with spinal pain. Further research is warranted to assess this association and the implications it may have for case management strategies to decrease opioid use.

Abstract
OBJECTIVES The objective of this historical cohort study was to determine the claimant and prescriber factors associated with receiving opioids at first postinjury dispense compared with non-steroidal anti-inflammatory drugs (NSAIDs) and skeletal muscle relaxants (SMRs) in a sample of workers' compensation claimants with low back pain (LBP) claims between 1998 and 2009 in British Columbia, Canada. METHODS Administrative workers' compensation, prescription and healthcare data were linked. The association between claimant factors (sociodemographics, occupation, diagnosis, comorbidities, pre-injury prescriptions and healthcare) and prescriber factors (sex, birth year, specialty) with drug class(es) at first dispense (opioids vs NSAIDs/SMRs) was examined with multilevel multinomial logistic regression. RESULTS Increasing days supplied with opioids in the previous year was associated with increased odds of receiving opioids only (1-14 days OR 1.62, 95% CI 1.51 to 1.75; ≥15 days OR 5.12, 95% CI 4.65 to 5.64) and opioids with NSAIDs/SMRs (1-14 days OR 1.49, 95% CI 1.39 to 1.60; ≥15 days OR 2.82, 95% CI 2.56 to 3.12). Other significant claimant factors included: pre-injury dispenses for NSAIDs, SMRs, antidepressants, anticonvulsants and sedative-hypnotics/anxiolytics; International Statistical Classification of Diseases and Related Health Problems, 9th Revision diagnosis; various pre-existing comorbidities; prior physician visits and hospitalisations; and year of injury, age, sex, health authority and occupation. Prescribers accounted for 25%-36% of the variability in the drug class(es) received, but prescriber sex, specialty and birth year did not explain observed between-prescriber variation. CONCLUSIONS During this period in the opioid crisis, early postinjury dispensing was multifactorial, with several claimant factors associated with receiving opioids at first prescription. Prescriber variation in drug class choice appears particularly important, but was not explained by basic prescriber characteristics.

Abstract
Abstract
Objective
Utilization of nonpharmacological pain management may prevent unnecessary use of opioids. Our objective was to evaluate the impact of chiropractic utilization upon use of prescription opioids among patients with spinal pain.
Design and Setting
We employed a retrospective cohort design for analysis of health claims data from three contiguous states for the years 2012–2017.
Subjects
We included adults aged 18–84 years enrolled in a health plan and with office visits to a primary care physician or chiropractor for spinal pain. We identified two cohorts of subjects: Recipients received both primary care and chiropractic care, and nonrecipients received primary care but not chiropractic care.
Methods
We performed adjusted time-to-event analyses to compare recipients and nonrecipients with regard to the risk of filling an opioid prescription. We stratified the recipient populations as: acute (first chiropractic encounter within 30 days of diagnosis) and nonacute (all other patients).
Results
The total number of subjects was 101,221. Overall, between 1.55 and 2.03 times more nonrecipients filled an opioid prescription, as compared with recipients (in Connecticut: hazard ratio [HR] = 1.55, 95% confidence interval [CI] = 1.11–2.17, P = 0.010; in New Hampshire: HR = 2.03, 95% CI = 1.92–2.14, P < 0.0001). Similar differences were observed for the acute groups.
Conclusions
Patients with spinal pain who saw a chiropractor had half the risk of filling an opioid prescription. Among those who saw a chiropractor within 30 days of diagnosis, the reduction in risk was greater as compared with those with their first visit after the acute phase.

Abstract
BACKGROUND A considerable proportion of adults with low back pain (LBP) suffer from depressive symptoms or depression. Those with depressive symptoms or depression may be at risk of poorer LBP recovery and require more health care. Understanding the role of prognostic factors for LBP is critically important to guide management and health services delivery. Our objective is to conduct a systematic review to assess the association between depressive symptoms or depression and health outcomes in adults with LBP with or without radiculopathy. METHODS Electronic databases including MEDLINE, Embase, CINAHL, and PsycINFO will be searched from inception to April 2019 to identify relevant studies. Additional citations will be identified by searching reference lists of included studies and related systematic reviews. Cohort and case-control studies assessing the association between depressive symptoms/depression and health outcomes in adults aged 16 years and older with LBP with or without radiculopathy will be included. The following will be included: depressive symptoms as measured on standardized questionnaires (e.g., Center for Epidemiologic Studies Depression Scale, Beck Depression Index), and depression as standardized diagnoses (e.g., International Classification of Diseases codes) or self-reported depression diagnosis on standardized questionnaires. Outcomes of interest are standardized measures for pain, disability, overall health status, satisfaction with care, and health care utilization. These are informed by core outcome domains that international expert panels consider important for LBP research. Pairs of reviewers will screen articles retrieved from the search, extract data, and assess risk of bias using the Risk Of Bias In Non-randomized Studies-of Exposures (ROBINS-E) tool. Reviewers will use these criteria to inform their judgment on the internal validity of studies (e.g., low, moderate, or high risk of bias). If studies are deemed homogeneous, a random effects meta-analysis on the association between depressive symptoms and health outcomes will be performed. The results of the included studies will be descriptively outlined if studies are deemed heterogeneous. DISCUSSION The impact of depressive symptoms and depression on health- and health care-related outcomes for LBP with or without radiculopathy will be assessed and quantified. Findings of this systematic review will advance our understanding of LBP prognosis, and guide decision-making and improve quality of care for adults with LBP.

Abstract
INTRODUCTION Low back pain (LBP) is a leading cause of disability associated with high healthcare utilisation and costs. Mental health symptoms are negative prognostic factors for LBP recovery; however, no population-based studies have assessed the joint effects of LBP and mental health symptoms on healthcare utilisation. This proposed study will characterise the health system burden of LBP and help identify priority groups to inform resource allocation and public health strategies. Among community-dwelling adult respondents of five cycles of the Canadian Community Health Survey (CCHS) in Ontario, we aim to assess the effect of self-reported LBP on healthcare utilisation and costs and assess whether this effect differs between those with and without self-reported mental health symptoms. METHODS AND ANALYSIS We designed a dynamic population-based cohort study using linkages of survey and administrative data housed at ICES. The Ontario sample of CCHS (2003-2004, 2005-2006, 2007/2008, 2009/2010, 2011/2012; total of ~1 30 000 eligible respondents) will be used to define the cohort of adults with self-reported LBP with and without mental health symptoms. Healthcare utilisation and costs will be assessed by linking health administrative databases. Follow-up ranges from 6 to 15 years (until 31 March 2018). Sociodemographic (eg, age, sex, education) and health behaviour (eg, comorbidities, physical activity) factors will be considered as potential confounders. Poisson and linear (log-transformed) regression models will be used to assess the association between LBP and healthcare utilisation and costs. We will assess effect modification with mental health symptoms on the additive and multiplicative scales and conduct sensitivity analyses to assess the impact of misclassification and residual confounding. ETHICS AND DISSEMINATION This study is approved by the University of Toronto Research Ethics Board. We will disseminate findings using a multifaceted knowledge translation strategy, including scientific conference presentations, publications in peer-reviewed journals and workshops with key knowledge users.

McGregor M, Nielsen A, Chung C, Fillery MD, Wakeland W, Mior S. System Dynamics to Investigate Opioid Use and Chiropractic Care for Chronic Musculoskeletal Pain. J Manipulative Physiol Ther 2019; 42:237-246. [PMID: 31221495 DOI: 10.1016/j.jmpt.2018.11.007] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2018] [Revised: 10/24/2018] [Accepted: 11/15/2018] [Indexed: 11/25/2022]
Abstract
OBJECTIVE The purpose of this investigation was to create a system dynamics (SD) model, including published data and required assumptions, as a tool for future research identifying the role of chiropractic care in the management of chronic, nonmalignant pain in a Canadian population. METHODS We present an illustrative case description of how we evaluated the feasibility of conducting a large-scale clinical trial to assess the impact of chiropractic care in mitigating excessive opioid use in Canada. We applied SD modeling using current evidence and key assumptions where such evidence was lacking. Modeling outcomes were highlighted to determine which potential factors were necessary to account for compelling study designs. RESULTS Results suggest that a future clinical study diverting patients with nonmalignant musculoskeletal pain early to the chiropractic stream of care could be most effective. System dynamics modeling also highlighted design challenges resulting from unresearched assumptions that needed to be proxied for model completion. Assumptions included changing rates in opioid-associated deaths and rates of success in treatment management of addicted patients. CONCLUSION In this case, SD modeling identified current research gaps and strong contenders for appropriate follow-up questions in a clinical research domain, namely the role of chiropractic care in the management of chronic, nonmalignant pain in a Canadian population.

Abstract
OBJECTIVES Chiropractic care may have value in improving patient outcomes and decreasing opioid use, but little is known about the impetus for or process of incorporating these services into conventional medical settings. The purpose of this qualitative study was to describe organizational structures, care processes, and perceived value of chiropractic integration within U.S. private sector medical facilities. DESIGN Multisite, comparative organizational case study. SETTINGS Nine U.S. private sector medical facilities with on-site chiropractic care, including five hospitals and four clinics. PARTICIPANTS One hundred and thirty-five key facility stakeholders including doctors of chiropractic (DCs), non-DC clinicians, support staff, administrators, and patients. METHODS Researchers conducted 2-day site visits to all settings. Qualitative data were collected from audio-recorded, semi-structured, role-specified, individual interviews; standardized organizational data tables; and archival document review. A three-member, interdisciplinary team conducted thematic content analysis of verbatim transcripts using an existing conceptual framework and emergent codes. RESULTS These nine medical facilities had unique organizational structures and reasons for initiating chiropractic care in their settings. Across sites, DCs were sought to take an evidence-based approach to patient care, work collaboratively within a multidisciplinary team, engage in interprofessional case management, and adopt organizational mission and values. Chiropractic clinics were implemented within existing human resources, physical plant, information technology, and administrative support systems, and often expanded over time to address patient demand. DCs usually were co-located with medical providers and integrated into the collaborative management of patients with musculoskeletal and co-morbid conditions. Delivery of chiropractic services was perceived to have high value among patients, medical providers, and administration. Patient clinical outcomes, patient satisfaction, provider productivity, and cost offset were identified as markers of clinic success. CONCLUSION A diverse group of U.S. private sector medical facilities have implemented chiropractic clinics, and a wide variety of facility stakeholders report high satisfaction with the care provided.

Abstract
Punctate midline myelotomy (PMM) has been successfully applied clinically in humans for the relief of intractable visceral pain. The operation is thought to work by interrupting the postsynaptic dorsal column pathway (PSDC) of the spinal cord. In fact, PMM was developed specifically for that purpose after it was demonstrated in rats that the PSDC conveyed about 90% of the visceral pain information to the thalamus. The application of PMM also to the problem of severe intractable back or spine pain was never tested, and it has never been established whether the PSDC pathway relates only to visceral pain or whether there may be a broader involvement with pain affecting structures of embryological midline origin, perhaps including the spine. Retrospective analyses of decades of results from various attempted myelotomy procedures in man for the relief of pain are consistent with the notion that the common element crucial to the successful midline or visceral pain relief was the interruption--even incomplete--of the PSDC pathway. Herein, we present evidence from a rat model of lumbar facet pain that interruption of the PSDC significantly reduces pain responses. The implications for the possible treatment of severe intractable spine pain in man are discussed.

Abstract
Since its inception, the chiropractic profession has been divided along ideological fault lines. These divisions have led to a profession wide schism, which has limited mainstream acceptance, utilisation, social authority and integration. The authors explore the historical origins of this schism, taking time to consider historical context, religiosity, perpetuating factors, logical fallacies and siege mentality. Evidence is then provided for a way forward, based on the positioning of chiropractors as mainstream partners in health care.

Abstract
OBJECTIVE The purpose of this study was to evaluate a chiropractic service for back pain patients integrated within a publicly funded, multidisciplinary, primary care community health center in Cambridge, Ontario, Canada. METHODS Patients consulting for back pain of any duration were referred by their medical doctor or nurse practitioner for chiropractic treatment at the community health center. Patients completed questionnaires at baseline and at discharge from the service. Data were collected prospectively on consecutive patients between January 2014 and January 2016. RESULTS Questionnaire data were obtained from 93 patients. The mean age of the sample was 49.0 ± 16.27 years, and 66% were unemployed. More than three-quarters (77%) had had their back pain for more than a month, and 68% described it as constant. According to the Bournemouth Questionnaire, Bothersomeness, and global improvement scales, a majority (63%, 74%, and 93%, respectively) reported improvement at discharge, and most (82%) reported a significant reduction in pain medication. More than three-quarters (77%) did not visit their primary care provider while under chiropractic care, and almost all (93%) were satisfied with the service. According to the EuroQol 5 Domain questionnaire, more than one-third of patients (39%) also reported improvement in their general health state at discharge. CONCLUSION Implementation of an integrated chiropractic service was associated with high levels of improvement and patient satisfaction in a sample of patients of low socioeconomic status with subacute and chronic back pain.

Abstract
STUDY DESIGN This study was a retrospective-cohort design involving a review of patient medical and cost records and a 2-year postsurgery follow-up outcome survey. OBJECTIVE To evaluate the functional and cost outcomes associated with recent lumbar fusion surgeries in Utah workers and compare these outcomes with a comparable prior study cohort. SUMMARY OF BACKGROUND DATA Lumbar fusion performed on injured workers has dramatically increased over the past 2 decades and this likely coincided with the increased use of more advanced surgical instrumentation. Considering the recent changes in lumbar fusion surgery, there is a need to identify how patient outcomes have changed among injured workers. MATERIALS AND METHODS Retrospective chart review and 2-year postsurgery follow-up survey of patient outcomes were performed. Postsurgical outcomes for this sample were compared with established norms for back pain patients and a previous cohort of compensated lumbar fusion patients obtained from Workers' Compensation Fund of Utah. RESULTS The current cohort evidenced a solid fusion rate of 89% and significant increase in the use of surgical instrumentation, particularly titanium fusion cages. Despite increased solid fusion rates, injured workers who have undergone lumbar fusion in Utah demonstrated equivalent and in some cases worse outcomes than those documented a decade ago. Specifically, there were significant increases in back pain dysfunction and narcotic medication usage in the current versus the past cohort. Medical and compensation costs for compensated lumbar fusion patients in Utah also significantly increased since the mid-1990s. CONCLUSION Over the past decade, injured workers who have undergone lumbar fusion in Utah showed an increase in solid fusion rates and costs without a corresponding improvement in patient outcomes.

Abstract
Hypoxemia (systemic oxygen desaturation) marks the presence, risk, and progression of many diseases. Episodic or nocturnal hypoxemia can be challenging to detect and quantify. A sensitive, specific, and convenient marker of recent oxygen desaturation represents an unmet medical need. Observations of acclimatization to high altitude in humans and animals reveals several proteosomic, ventilatory, and hematological responses to low oxygen tension. Of these, increased red cell distribution width (RDW) appears to have the longest persistence. Literature review and analyses of a 2M patient database across the full disease pathome revealed that increased RDW is predictive of poor outcome for certain diseases including many if not all hypoxigenic conditions. Comprehensive review of diseases impacting the respiratory axis show many are associated with increased RDW and no apparent counterexamples. The mechanism linking RDW to outcome is unknown. Conjectural roles for iron deficiency, inflammation, and oxidative stress have not been born out experimentally. Sports-doping studies show that erythropoietin (EPO) injection can induce formation of unusually large red blood cells (RBC) in sufficient numbers to increase RDW. Because endogenous EPO responds strongly to hypoxemia, this molecule could potentially mediate a long-lived RDW response to low oxygenation. RDW may be a guidepost signaling that unexploited information is embedded in subtle RBC variation. Applying modern techniques of measurement and analysis to certain RBC characteristics may yield a more specific and sensitive marker of chronic pulmonary and circulatory diseases, sleep apnea, and opioid inhibition of breathing.

Abstract
STUDY DESIGN A population-based cross-sectional survey. OBJECTIVE The aim of this study was to compare the prevalence of illicit drug use among US adults with and without chronic low back pain (cLBP). SUMMARY OF BACKGROUND DATA Although addictive medications, such as opioids and benzodiazepines, are frequently prescribed to patients with cLBP, little is known about illicit drug use among Americans with cLBP. METHODS We used data from the back pain survey, administered to a representative sample of US adults aged 20 to 69 years (N = 5103) during the 2009 to 2010 cycle of the National Health and Nutrition Examination Survey (NHANES). Participants with pain in the area between the lower posterior margin of the ribcage and the horizontal gluteal fold for at least 3 months were classified as having cLBP (N = 700). The drug use questionnaire was self-administered in a private setting, and included data on lifetime and current use of marijuana or hashish, cocaine, heroin, and methamphetamine. Chi-square tests, one-way analysis of variance, and logistic regression, adjusted for age, gender, race, and level of education, were used for comparisons. RESULTS About 46.5% of US adults with cLBP used marijuana versus 42% of those without cLBP [Adjusted odds ratio (aOR) 1.36, 95% confidence interval (95% CI) 1.06-1.74]. About 22% versus 14% used cocaine (aOR 1.80, 95% CI 1.45-2.24), 9% versus 5% used methamphetamine (aOR 2.03, 95% CI 1.30-3.16), and 5% versus 2% used heroin (aOR 2.43, 95% CI 1.44-4.11). Subjects with cLBP who reported lifetime illicit drug use were more likely to have an active prescription for opioid analgesics than those without illicit drug use history: 22.5% versus 15.3%, P = 0.018. CONCLUSION cLBP in community-based US adults was associated with higher odds of using marijuana, cocaine, heroin, and methamphetamine. Prescription opioid analgesic use was more common in cLBP sufferers with a history of illicit drug use. LEVEL OF EVIDENCE 2.

Abstract
BACKGROUND The purpose of this study was to determine if primary care patients with low back pain (LBP) cluster into definable care utilization subgroups that can be explained by patient and provider characteristics. MATERIALS AND METHODS Adult primary care patients with an incident LBP encounter were identified from Geisinger Clinic electronic health records over 5 years. Two-thirds of the cohort had only one to two encounters. Principal component analysis was applied to the data from the remaining one-third on use of ambulatory, inpatient, emergency department, and surgery care and use of magnetic resonance imaging, injections, and opioids in 12 months following the incident encounter. Groups were compared on demographics, health behaviors, chronic and symptomatic disease burden, and a measure of physician efficiency. RESULTS Six factors with eigenvalues >1.5 explained 71% of the utilization variance. Patient subgroups were defined as: 1-2 LBP encounters; 2+ surgeries; one surgery; specialty care without primary care; 3+ opioid prescriptions; laboratory dominant care; and others. The surgery and 3+ opioid subgroups, while accounting for only 10.4% of the cohort, had used disproportionately more magnetic resonance imaging, emergency department, inpatient, and injectable resources. The specialty care subgroup was characterized by heavy use of inpatient care and the lowest use of injectables. Anxiety disorder and depression were not more prevalent among the surgery patients than in the others. Surgery patients had features in common with specialty care patients, but were older, had higher prevalence of Fibromyalgia, and were associated primary care physicians with worse efficiency scores. CONCLUSION LBP care utilization is highly variable and concentrated in small subgroups using disproportionate amounts of potentially avoidable care that reflect both patient and provider characteristics.

Abstract
BACKGROUND CONTEXT Various studies have reported on the increasing use and costs of diagnostic imaging for low back pain (LBP) in the United States. However, it is unclear whether the methods used in these studies allowed for meaningful comparisons or whether the reported use data can be used to develop evidence-based use benchmarks. PURPOSE The primary purpose of this study was to review previous estimates of the use of diagnostic imaging for LBP in the United States. STUDY DESIGN/SETTING The study design is a systematic review of published literature. METHODS A search through May 2012 was conducted using keywords and free text terms related to health services and LBP in Medline and Health Policy Reference; results were screened for relevance independently, and full-text studies were assessed for eligibility. Only studies published in English since the year 2000 reporting on use of diagnostic imaging for LBP using claims data from the United States were included. Reporting quality was assessed using a modified Downs and Black tool for observational studies. RESULTS The search strategy yielded 1,102 citations, seven of which met the criteria for eligibility. Studies reported use from commercial health plans (N=4) and Medicare (N=3), with sample sizes ranging from 13,760 to 740,467 members with LBP from specific states or across the United States. The number of diagnostic codes used to identify nonspecific LBP ranged from 2 to 66; other heterogeneity was noted in the methods used across these studies. In commercial health plans, use of radiography occurred in 12.0% to 32.2% of patients with LBP, magnetic resonance imaging (MRI) was used in 16.0% to 21.0%, computed tomography (CT) was used in 1.4% to 3.0%, and MRI and/or CT was used in 10.9% to 16.1%. Findings in Medicare populations were 22.9% to 48.2% for radiography, 11.6% for MRI, and 10.4% to 16.3% for MRI and/or CT. CONCLUSIONS The reported use of diagnostic imaging for LBP varied across the studies reviewed; differences in methodology made meaningful comparisons difficult. Standardizing methods for performing and reporting analyses of claims data related to use could facilitate efforts by third-party payers, health care providers, and researchers to identify and address the perceived overuse of diagnostic imaging for LBP.

Abstract
OBJECTIVE The study aims to examine real-world effects of duloxetine treatment for low back pain (LBP). METHODS The study identified employees with ≥1 LBP diagnosis and ≥1 duloxetine prescription within a year after LBP diagnosis from a privately insured claims database (2004-2007). Duloxetine-treated employees were propensity score matched to employees initiating another pharmacological/noninvasive treatment in the same month from LBP diagnosis. Treatment patterns and costs were compared over the 6 months following treatment initiation. RESULTS Relative to controls, duloxetine-treated employees (N = 753) had significantly lower rates of other pharmacological/noninvasive therapies and a similar LBP surgery rate (1.7% vs 2.8%, P = 0.1573). Duloxetine-treated employees, despite higher pharmacy costs, had similar direct (health care) costs ($4,935 vs $5,649, P = 0.2662), and significantly lower indirect (workloss) costs ($1,723 vs $2,198, P = 0.0036). CONCLUSIONS Duloxetine treatment in LBP employees was associated with reduced rates of many nonsurgical therapies and lower indirect costs. The findings are limited by the observational study design and unmeasured potential confounders.

The increasing prevalence of chronic pain with its major societal impact and the escalating use of opioids in managing it, along with their misuse, abuse, associated fatalities and costs, are epidemics in modern medicine. Over the past two decades, multiple lessons have been learned addressing various issues of abuse. Multiple measures have already been incorporated and more are expected to be incorporated in the future, which in turn may curtail the abuse of drugs and reduce healthcare costs, but these measures may also jeopardize access to appropriate pain treatment. This manuscript describes the lessons learned from the misuse, abuse and diversion of opioids, escalating healthcare costs and the means to control this epidemic.

Abstract
UNLABELLED BACKGROUND Tracking how clinicians treat patients provides an opportunity to explore how the clinical management of common musculoskeletal disorders evolves over time. We present an uncontrolled before-after study of a primary care physician's management of low back pain and describe how his involvement in an interprofessional collaborative practice was associated with a change in the management of patients with low back pain. METHOD Data from the electronic medical record of one primary care physician who participated in a study of a model of chiropractic-medical collaboration were retrospectively collected. Records of a sample of consecutive patients prior to the start (i.e. pre-study, n = 51) and at the end of the collaborative study (i.e. study, n = 49) were collected. RESULTS Demographics were similar in both groups but median number of physician visits (2.5 and 1.0), average prescriptions per patients (1.24 and 0.47), and total number of narcotic prescriptions (14 and 6) differed between pre-study and study groups, respectively. Separate analysis of only the records of low back pain study patients revealed that 61% were referred for chiropractic care during the study period. Patients who were not referred had more neurological deficits and leg pain but back pain severity and average number of prescriptions was about the same. Referred patients in the study group had about 25% fewer physician visits and imaging requests. CONCLUSION Based on this study of a single primary care physician, we hypothesize that doctors may change their prescribing behaviours and consultation rate for patients with low back pain when engaged in interprofessional collaborative care. Further research is required to test this observation in the population.

Abstract
The diagnosis and treatment of low back pain must be standardized, based on evidence and solid research. The cost to individuals and society is great and only those diagnostic tests or treatments that can improve the quality and cost of care should be advocated.

Abstract
BACKGROUND Little is known about the real-world treatment patterns and costs of patients with chronic low back pain (CLBP) who are treated with duloxetine compared with those receiving other non-surgical treatments. OBJECTIVE Our objective was to compare the real-world treatment patterns and costs between patients with CLBP who initiated duloxetine and matched controls who initiated another non-surgical treatment. METHODS The study sample was selected from a US privately insured claims database (2004-8). Selected patients were aged 18-64 years, and had a low back pain (LBP) diagnosis (per Healthcare Effectiveness Data and Information Set [HEDIS] specifications) with a subsequent CLBP-qualifying diagnosis recorded ≥90 days after the initial LBP diagnosis. Duloxetine-treated patients had ≥1 duloxetine prescription within 6 months after CLBP diagnosis, no prior duloxetine claim, and continuous eligibility ≥12 months before first LBP diagnosis and ≥6 months after index duloxetine prescription (study period). Because duloxetine patients had higher rates of co-morbidities, 553 duloxetine-treated patients were matched to 553 control patients who initiated another non-surgical LBP treatment based on propensity score and time from first LBP diagnosis to treatment initiation. A subset (n = 103 each) of matched employees with disability data was also analysed to assess work loss. Main outcomes measures included study period treatment rates and direct (medical and drug) costs from a third-party payer perspective and employee indirect (work-loss) costs. McNemar tests were used to compare LBP treatment rates. Bias-corrected bootstrapping t-tests were used to compare costs. RESULTS After matching, the two groups had balanced baseline characteristics including demographics, LBP diagnostic categories, co-morbidity profiles, resource use, treatment patterns and mean direct costs. During the 6-month study period, matched duloxetine-treated patients had significantly lower rates of other pharmacological therapy (e.g. 56.2% vs 64.9% narcotic opioids, p = 0.0024; 34.9% vs 49.5% NSAIDs, p < 0.0001) and non-invasive therapy (28.8% vs 38.5% chiropractic therapy, p = 0.0007; 25.5% vs 35.4% physical therapy, p = 0.0004; 17.5% vs 28.4% exercise therapy, p < 0.0001) than controls. Duloxetine-treated patients versus controls had similar back surgery rates (2.2% vs 3.8%; p = 0.1127) and similar direct costs ($US7658 vs $US7439; p = 0.8119). Among CLBP employees, duloxetine-treated employees versus controls had lower rates of other non-surgical therapy, similar back surgery rates (0.0% vs 3.9%; p = 0.1250), lower total direct and indirect costs ($US5227 vs $US7299; p = 0.0418), and similar indirect costs ($US1806 vs $US2664; p = 0.0528). CONCLUSIONS Duloxetine treatment in CLBP patients/employees versus other non-surgical treatment was associated with reduced rates of non-surgical therapies and similar back surgery rates, without increased costs.

Abstract
BACKGROUND This research addresses the need for population-based studies on the burden of chronic low back pain (CLBP) by examining healthcare service use and costs for patients with and without neuropathic components in the US population. METHODS Data were analyzed from PharMetrics IMS LifeLink™ US Claims Database (2006-2008). Patients (≥18 years) with 36 months continuous enrollment, ICD-9 code for low back pain, and claims in 3 out of 4 consecutive months in the 12-month prospective period were included and classified with CLBP. Patients were further classified with a neuropathic component (wNP) and without a neuropathic component (woNP) based on ICD-9 codes. Healthcare resources, physical therapy, prescription medication use, and associated costs were assessed for the period January 1-December 31, 2008. RESULTS A number of patients (39,425) were identified with CLBP (90.4% wNP). Patients wNP included more women, were older and more likely to have clinically diagnosed depression, and made significantly greater use of any prescription medication at index event, opioids (particularly schedule II), and healthcare resources. Total direct costs of CLBP-related resource use were ∼US$96 million over a 12-month follow-up. CLBP wNP accounted for 96% of total costs and mean annual cost of care/patient was ∼160% higher than CLBP patients woNP (US$ 2577 vs US$ 1007, p < 0.0001). LIMITATIONS This study was descriptive and was not designed to demonstrate causality between diagnosis, treatment, and outcomes. Resource use and costs for reasons other than LBP were not included. Patients with neuropathic pain are more likely to seek treatment; therefore CLBP patients with a non-neuropathic component may be under-represented. CONCLUSIONS The disproportionately high share of interventional resource use in CLBP wNP suggests greater need for new treatment options that more comprehensively manage the range of pain symptoms and signaling mechanisms involved, to help improve patient outcomes and reduce the burden on healthcare systems.

Real-world practice patterns, health-care utilization, and costs in patients with low back pain: the long road to guideline-concordant care. Spine J 2011; 11:622-32.

Abstract
BACKGROUND CONTEXT Treatment guidelines suggest that most acute low back pain (LBP) episodes substantially improve within a few weeks and that immediate use of imaging and aggressive therapies should be avoided. PURPOSE Assess the actual practice patterns of imaging, noninvasive therapy, medication use, and surgery in patients with LBP, and compare their costs to those of matched controls without LBP. STUDY DESIGN A retrospective analysis of claims data from 40 self-insured employers in the United States. PATIENT SAMPLE The study sample included 211,551 patients, aged 18 to 64 years, with one LBP diagnosis or more (per Healthcare Effectiveness Data and Information Set specification) during 2004 to 2006, identified from a claims database. Patients had continuous eligibility for 12 months or more after their index LBP diagnosis (study period), for 6 months or more before their index diagnosis (baseline period), and no other LBP diagnosis during the baseline period. Patients with LBP were matched to a random cohort of patients without LBP by age, gender, employment status, and index year. OUTCOMES MEASURES Physiological measures (eg, imaging and diagnostic tests), functional measures (eg, pharmacologic and nonpharmacologic treatment for LBP, health-care resource use), and direct (medical and prescription drug) and indirect (disability and medically related absenteeism) costs were assessed within the year after the LBP diagnosis. METHODS Univariate analyses described treatment patterns and compared baseline characteristics and study period costs. RESULTS Patients with LBP had significantly higher rates of baseline comorbidities and resource use compared with controls. Of patients with LBP, 41.6% had imaging mean (median) [standard deviation] 34.3 (0) [78.6] days after the LBP diagnosis. Most patients with LBP (69.4%) used medications starting 51.9 (8) [86.2] days after the diagnosis. Opioids were commonly prescribed early (41.6% of patients; after 82.8 (25) [105.9] days). Of patients with LBP, 2.05% had surgery during the study period. Patients with LBP were likely to have chiropractic treatment first, followed by pharmacotherapy with muscle relaxants and nonsteroidal anti-inflammatory drugs. Except for less surgery, these findings also held for patients with only nonspecific LBP. Patients with LBP had higher mean direct costs compared with controls ($7,211 vs. $2,382, respectively; p<.0001), with surgery patients having mean direct costs of $33,931. CONCLUSIONS Contrary to clinical guidelines, many patients with LBP start incurring significant resource use and associated expenses soon after the index diagnosis. Achieving guideline-concordant care will require substantial changes in LBP practice patterns.

Abstract
STUDY DESIGN This study is an analysis of the National Hospital Ambulatory Medical Care Survey (NHAMCS), a large sample representative of all emergency department (ED) visits throughout the United States. OBJECTIVE To use NHAMCS to describe the frequency of ED visits for the treatment of low back pain, and the diagnostic and therapeutic strategies employed by emergency clinicians. SUMMARY OF BACKGROUND DATA Low back pain is common in the general population. While it accounts for 2.5% of all outpatient office visits, the role of the ED has yet to be described. METHODS We included cases if they had both a reason for visit related to back pain and a primary ED discharge ICD9 code consistent with low back pain. The outcomes included frequency of ED use, and frequency of various diagnostic and therapeutic strategies. Individual patient visits are weighted so that data can be extrapolated to all ED visits throughout the United States. RESULTS Low back pain related disorders caused 2.63 million (95% CI: 2.32, 2.93 million) annual ED visits in the US. Of all patients with low back pain, 30.5% (28.1, 32.9) had a plain radiograph; 9.6% (95% CI: 7.2, 12.6) had a CT or MRI in 2006 compared with 3.2% (95% CI: 2.0, 5.1) in 2002 (P for trend <0.01). Age and type of insurance were associated with advanced imaging, though geographic region was not. Of medications either administered in the ED or prescribed at discharge, the most frequently used classes were opioids (61.0%, 95% CI: 58.4, 63.5), followed by nonsteroidal anti-inflammatory drugs (49.9%, 95% CI: 47.2, 52.7) and muscle relaxants (43.1%, 95% CI: 40.4, 45.8). CONCLUSION Low back pain related disorders are a frequent cause of ED visit. Diagnostic imaging is performed in one-third of all patients. There was a strong secular trend in use of advanced imaging; patients were nearly 3 times as likely to receive a CT or MRI in 2006 as they were 4 years earlier. Although opioids were administered or prescribed to two-thirds of patients, use of therapeutic agents was generally in keeping with guideline recommendations.

Abstract
In this article, the epidemiology of back pain and the use of a variety of treatments for back pain in the United States are reviewed. The dilemma faced by medical providers caring for patients with low back pain is examined in the context of epidemiologic data. Back pain is becoming increasingly common and a growing number of treatment options are being used with increasing frequency in clinical practice. However, limited evidence exists to demonstrate the effectiveness of these treatments. In addition, health-related quality of life for persons with back pain is not improving despite the availability and use of an expanding array of treatments. This dilemma poses a difficult challenge for medical providers treating individual patients who suffer from back pain.
