Association Between Chiropractic Use and Opioid Receipt Among Patients with Spinal Pain: A Systematic Review and Meta-analysis

The prevalence and burden of musculoskeletal disorders amongst Indigenous people in Pimicikamak, northern Manitoba, Canada: A community health survey

Objectives

To investigate the prevalence of spine symptoms and spine disability, self-care and care seeking behaviors in a random sample of Indigenous adults residing in Cross Lake, northern Manitoba, Canada.

Study design and setting

Orally administered survey in Cree or English to a representative sample of Pimicikamak citizens from the treaty (n = 150/1931 houses) and non-treaty (n = 20/92 houses) land, between May and July 2023. Questions (n = 154) were derived from the 2018 First Nations Regional Health Survey, 2020 Canadian Community Health Survey, and 2021 The Global Burden of Disease study, covering demographics, spine symptoms, chronic conditions, activity limitations, general health, self-care, medication, and satisfaction with care. We used descriptive and cross-tabulations and consulted the community for data interpretation.

Results

The survey was completed by 130 adults (65 % females, mean age, 48.4 years). Nearly all participants (89.6 %) reported having spine symptoms in the past four weeks, with a majority experiencing activity limitations lasting one day or more due to neck (77.9 %) or low back pain (55.6 %). Chronic neck and low back pain "sometimes or often" limited activities of daily living (52.8 % and 74.1 % respectively). Nearly two-third (65.4 %) did not have concomitant mood problems. Future preferred care included self-care (88.5 %), over-the- counter medication (64.6 %), seeing an allied care provider (45.4 %), a traditional healer (26.2 %), a nurse or a medical doctor (22.3 %).

Conclusion

Spine symptoms were highly prevalent and significantly impacted activities of daily living. Nearly half of respondents felt that they could benefit from care provided by allied health providers.

Implementation, intervention, and downstream costs for implementation of a multidisciplinary complex pain clinic in the Veterans Health Administration

OBJECTIVE

To determine the budget impact of implementing multidisciplinary complex pain clinics (MCPCs) for Veterans Health Administration (VA) patients living with complex chronic pain and substance use disorder comorbidities who are on risky opioid regimens.

DATA SOURCES AND STUDY SETTING

We measured implementation costs for three MCPCs over 2 years using micro-costing methods. Intervention and downstream costs were obtained from the VA Managerial Cost Accounting System from 2 years prior to 2 years after opening of MCPCs.

STUDY DESIGN

Staff at the three VA sites implementing MCPCs were supported by Implementation Facilitation. The intervention cohort was patients at MCPC sites who received treatment based on their history of chronic pain and risky opioid use. Intervention costs and downstream costs were estimated with a quasi-experimental study design using a propensity score-weighted difference-in-difference approach. The healthcare utilization costs of treated patients were compared with a control group having clinically similar characteristics and undergoing the standard route of care at neighboring VA medical centers. Cancer and hospice patients were excluded.

DATA COLLECTION/EXTRACTION METHODS

Activity-based costing data acquired from MCPC sites were used to estimate implementation costs. Intervention and downstream costs were extracted from VA administrative data.

PRINCIPAL FINDINGS

Average Implementation Facilitation costs ranged from $380 to $640 per month for each site. Upon opening of three MCPCs, average intervention costs per patient were significantly higher than the control group at two intervention sites. Downstream costs were significantly higher at only one of three intervention sites. Site-level differences were due to variation in inpatient costs, with some confounding likely due to the COVID-19 pandemic. This evidence suggests that necessary start-up investments are required to initiate MCPCs, with allocations of funds needed for implementation, intervention, and downstream costs.

CONCLUSIONS

Incorporating implementation, intervention, and downstream costs in this evaluation provides a thorough budget impact analysis, which decision-makers may use when considering whether to expand effective programming.

Medication recommendations for treatment of lumbosacral radiculopathy: A systematic review of clinical practice guidelines

OBJECTIVE

The purpose of this systematic review was to ascertain guideline-recommended pharmaceutical approaches to lumbosacral radicular symptoms, assess the quality of the clinical practice guidelines (CPGs) with the Appraisal of Guidelines for Research and Evaluation II (AGREE II) tool, and qualitatively synthesize the guideline recommendations.

LITERATURE SURVEY

Literature searches were performed in PubMed, Cochrane Database of Systematic Reviews, Index to Chiropractic Literature, Allied and Complementary Medicine Database (AMED), Cumulative Index for Nursing and Allied Health Literature (CINAHL), and Physiotherapy Evidence Database (PEDro). We included guidelines published between January 1, 2017, and January 9, 2022, written in the English language, related to radiculopathy, sciatica, and/or low back pain with leg pain, and that provided recommendations on oral medication.

METHODOLOGY

The review was performed in accordance with Preferred Reporting Items for Systemic Reviews and Meta-Analyses (PRISMA) and the protocol was pre-registered with the International Prospective Register of Systematic Reviews (PROSPERO). Eligibility screening, full-text review, extraction of information pertaining to pharmacological management, and synthesis of results were performed independently by two authors and a third investigator was recruited to arbitrate any disagreements. The AGREE II tool was administered by four authors to appraise CPG quality.

SYNTHESIS

After screening 413 citations and assessing 37 full-text articles, 11 CPGs met the inclusion criteria. They represented seven countries (Belgium, Canada, England, France, Japan, Korea, and United States) and three continents (Asia, Europe, and North America), as well as the Global Spine Care Initiative aimed at a worldwide presence. The mean overall AGREE II score was 87.1% (standard deviation [SD] 12.6%), generally reflecting high-quality CPGs. The highest domain mean score was for Clarity of Presentation (96.7%, SD 4.4%), and the lowest was Applicability (75.6%, SD 22.8%). Five classes of medications were recommended by at least one CPG: anticonvulsants, antidepressants, oral corticosteroids, nonsteroidal anti-inflammatory drugs (NSAIDs), and opioids.

CONCLUSIONS

The most common medication class recommended by the CPGs for lumbar radiculopathy was antidepressants. No CPGs recommended prescribing acetaminophen, benzodiazepines, muscle relaxants, or antibiotics. There was very little agreement between the CPGs, and all the medication classes had at least one CPG recommended against its use. Three guidelines reviewed did not recommend any medications due to lack of supporting literature, and instead recommended nonpharmacologic therapy.

Integrated clinical opportunities for training offered through US doctor of chiropractic programs

OBJECTIVE

The primary objective of this study was to assess, summarize, and compare the current integrated clinical learning opportunities offered for students who matriculated in US doctor of chiropractic programs (DCPs).

METHODS

Two authors independently searched all accredited DCP handbooks and websites for clinical training opportunities within integrated settings. The 2 data sets were compared with any discrepancies resolved through discussion. We extracted data for preceptorships, clerkships, and/or rotations within the Department of Defense, Federally Qualified Health Centers, multi-/inter-/transdisciplinary clinics, private/public hospitals, and the Veterans Health Administration. Following data extraction, officials from each DCP were contacted with a request to verify the collected data.

RESULTS

Of the 17 DCPs reviewed, all but 3 offered at least 1 integrated clinical experience, while 41 integrated clinical opportunities were the most offered by a single DCP. There was an average of 9.8 (median 4.0) opportunities per school and an average of 2.5 (median 2.0) clinical setting types. Over half (56%) of all integrated clinical opportunities were within the Veterans Health Administration, followed by multidisciplinary clinic sites (25%).

CONCLUSION

This work presents preliminary descriptive information of the integrated clinical training opportunities available through DCPs.

Identifying and addressing patient substance use: a survey of chiropractic clinicians

BACKGROUND

Chiropractors commonly encounter patients who present for spine pain with parallel substance use. There is currently no widespread training within the chiropractic profession to prepare chiropractors to recognize and address substance use in clinical practice. The purpose of this study was to examine chiropractors' confidence, self-perceptions, and interest in education associated with identifying and addressing patient substance use.

METHODS

A 10-item survey was developed by the authors. The survey addressed chiropractors' assessment of their training, experiences, and educational interest/needs regarding identifying and addressing patient substance use. The survey instrument was uploaded to Qualtrics and was electronically distributed to chiropractic clinicians at active and accredited English-speaking Doctor of Chiropractic degree programs (DCPs) in the United States.

RESULTS

A total of 175 individual survey responses were returned from a total of 276 eligible participants (63.4% response rate) from 16 out of 18 active and accredited English-speaking DCPs (88.8% of DCPs) in the United States. Nearly half of respondents strongly disagreed or disagreed (n = 77, 44.0%) that they were confident in their ability to identify patients who misuse prescription medication. The majority of respondents (n = 122, 69.7%) indicated that they did not have an established referral relationship with local clinical providers who provide treatment for individuals who use drugs or misuse alcohol or prescription medications. Most respondents strongly agreed or agreed (n = 157, 89.7%) that they would benefit from participating in a continuing education course on topics related to patients who use drugs or misuse alcohol or prescription medications.

CONCLUSIONS

Chiropractors indicated a need for training to help them identify and address patient substance use. There is a demand among chiropractors to develop clinical care pathways for chiropractic referrals and collaboration with health care professionals who provide treatment for individuals who use drugs or misuse alcohol or prescription medications.

A systematic review of chiropractic care for fall prevention: rationale, state of the evidence, and recommendations for future research

BACKGROUND

Falls in older adults are a significant and growing public health concern. There are multiple risk factors associated with falls that may be addressed within the scope of chiropractic training and licensure. Few attempts have been made to summarize existing evidence on multimodal chiropractic care and fall risk mitigation. Therefore, the broad purpose of this review was to summarize this research to date. BODY: Systematic review was conducted following PRISMA guidelines. Databases searched included PubMed, Embase, Cochrane Library, PEDro, and Index of Chiropractic Literature. Eligible study designs included randomized controlled trials (RCT), prospective non-randomized controlled, observational, and cross-over studies in which multimodal chiropractic care was the primary intervention and changes in gait, balance and/or falls were outcomes. Risk of bias was also assessed using the 8-item Cochrane Collaboration Tool. The original search yielded 889 articles; 21 met final eligibility including 10 RCTs. One study directly measured the frequency of falls (underpowered secondary outcome) while most studies assessed short-term measurements of gait and balance. The overall methodological quality of identified studies and findings were mixed, limiting interpretation regarding the potential impact of chiropractic care on fall risk to qualitative synthesis.

CONCLUSION

Little high-quality research has been published to inform how multimodal chiropractic care can best address and positively influence fall prevention. We propose strategies for building an evidence base to inform the role of multimodal chiropractic care in fall prevention and outline recommendations for future research to fill current evidence gaps.

Systematic review of guideline-recommended medications prescribed for treatment of low back pain

OBJECTIVE

To identify and descriptively compare medication recommendations among low back pain (LBP) clinical practice guidelines (CPG).

METHODS

We searched PubMed, Cochrane Database of Systematic Review, Index to Chiropractic Literature, AMED, CINAHL, and PEDro to identify CPGs that described the management of mechanical LBP in the prior five years. Two investigators independently screened titles and abstracts and potentially relevant full text were considered for eligibility. Four investigators independently applied the Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument for critical appraisal. Data were extracted for pharmaceutical intervention, the strength of recommendation, and appropriateness for the duration of LBP.

RESULTS

316 citations were identified, 50 full-text articles were assessed, and nine guidelines with global representation met the eligibility criteria. These CPGs addressed pharmacological treatments with or without non-pharmacological treatments. All CPGS focused on the management of acute, chronic, or unspecified duration of LBP. The mean overall AGREE II score was 89.3% (SD 3.5%). The lowest domain mean score was for applicability, 80.4% (SD 5.2%), and the highest was Scope and Purpose, 94.0% (SD 2.4%). There were ten classifications of medications described in the included CPGs: acetaminophen, antibiotics, anticonvulsants, antidepressants, benzodiazepines, non-steroidal anti-inflammatory drugs (NSAIDs), opioids, oral corticosteroids, skeletal muscle relaxants (SMRs), and atypical opioids.

CONCLUSIONS

Nine CPGs, included ten medication classes for the management of LBP. NSAIDs were the most frequently recommended medication for the treatment of both acute and chronic LBP as a first line pharmacological therapy. Acetaminophen and SMRs were inconsistently recommended for acute LBP. Meanwhile, with less consensus among CPGs, acetaminophen and antidepressants were proposed as second-choice therapies for chronic LBP. There was significant heterogeneity of recommendations within many medication classes, although oral corticosteroids, benzodiazepines, anticonvulsants, and antibiotics were not recommended by any CPGs for acute or chronic LBP.

Characteristics and productivity of the chiropractic workforce of the Veterans Health Administration

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.

Initial Choice of Spinal Manipulation Reduces Escalation of Care for Chronic Low Back Pain Among Older Medicare Beneficiaries

STUDY DESIGN

We combined elements of cohort and crossover-cohort design.

OBJECTIVE

The objective of this study was to compare longterm outcomes for spinal manipulative therapy (SMT) and opioid analgesic therapy (OAT) regarding escalation of care for patients with chronic low back pain (cLBP).

SUMMARY OF BACKGROUND DATA

Current evidence-based guidelines for clinical management of cLBP include both OAT and SMT. For long-term care of older adults, the efficiency and value of continuing either OAT or SMT are uncertain.

METHODS

We examined Medicare claims data spanning a five-year period. We included older Medicare beneficiaries with an episode of cLBP beginning in 2013. All patients were continuously enrolled under Medicare Parts A, B, and D. We analyzed the cumulative frequency of encounters indicative of an escalation of care for cLBP, including hospitalizations, emergency department visits, advanced diagnostic imaging, specialist visits, lumbosacral surgery, interventional pain medicine techniques, and encounters for potential complications of cLBP.

RESULTS

SMT was associated with lower rates of escalation of care as compared to OAT. The adjusted rate of escalated care encounters was approximately 2.5 times higher for initial choice of OAT vs. initial choice of SMT (with weighted propensity scoring: rate ratio 2.67, 95% confidence interval 2.64-2.69, P < .0001).

CONCLUSION

Among older Medicare beneficiaries who initiated long-term care for cLBP with opioid analgesic therapy, the adjusted rate of escalated care encounters was significantly higher as compared to those who initiated care with spinal manipulative therapy.Level of Evidence: 3.

Association between chiropractic care and use of prescription opioids among older medicare beneficiaries with spinal pain: a retrospective observational study

Background

The burden of spinal pain can be aggravated by the hazards of opioid analgesics, which are still widely prescribed for spinal pain despite evidence-based clinical guidelines that identify non-pharmacological therapies as the preferred first-line approach. Previous studies have found that chiropractic care is associated with decreased use of opioids, but have not focused on older Medicare beneficiaries, a vulnerable population with high rates of co-morbidity and polypharmacy. The purpose of this investigation was to evaluate the association between chiropractic utilization and use of prescription opioids among older adults with spinal pain.

Methods

We conducted a retrospective observational study in which we examined a nationally representative multi-year sample of Medicare claims data, 2012–2016. The study sample included 55,949 Medicare beneficiaries diagnosed with spinal pain, of whom 9,356 were recipients of chiropractic care and 46,593 were non-recipients. We measured the adjusted risk of filling a prescription for an opioid analgesic for up to 365 days following diagnosis of spinal pain. Using Cox proportional hazards modeling and inverse weighted propensity scoring to account for selection bias, we compared recipients of both primary care and chiropractic to recipients of primary care alone regarding the risk of filling a prescription.

Results

The adjusted risk of filling an opioid prescription within 365 days of initial visit was 56% lower among recipients of chiropractic care as compared to non-recipients (hazard ratio 0.44; 95% confidence interval 0.40–0.49).

Conclusions

Among older Medicare beneficiaries with spinal pain, use of chiropractic care is associated with significantly lower risk of filling an opioid prescription.

Association of chiropractic integration in an Ontario community health centre with prescription opioid use for chronic non-cancer pain: a mixed methods study protocol

INTRODUCTION

Emerging evidence from a number of primary care centres suggests that integration of chiropractic services into chronic pain management is associated with improved clinical outcomes and high patient satisfaction as well as with reductions in physician visits, specialist referrals use of advanced imaging and prescribing of analgesics. However, formal assessments of the integration of chiropractic services into primary care settings are sparse, and the impact of such integration on prescription opioid use in chronic pain management remains uncertain. To help address this knowledge gap, we will conduct a mixed methods health service evaluation of an integrated chiropractic back pain programme in an urban community health centre in Ontario, Canada. This centre provides services to vulnerable populations with high unemployment rates, multiple comorbidities and musculoskeletal disorders that are commonly managed with prescription opioids.

METHODS AND ANALYSIS

We will use a sequential explanatory mixed methods design, which consists of a quantitative phase followed by a qualitative phase. In the quantitative phase, we will conduct a retrospective chart review and evaluate whether receipt of chiropractic services is associated with reduced opioid use among patients already prescribed opioid therapy for chronic pain. We will measure opioid prescriptions (ie, opioid fills, number of refills and dosages) by reviewing electronic medical records of recipients and non-recipients of chiropractic services between 1 January 2014 and 31 December 2020 and use multivariable regression analysis to examine the association. In the qualitative phase, we will conduct in-depth, one-on-one interviews of patients and their general practitioners to explore perceptions of chiropractic integration and its impact on opioid use.

ETHICS AND DISSEMINATION

This study was approved by the Hamilton Integrated Research Ethics Board at McMaster University (approval number 2021-10930). The results will be disseminated via peer-reviewed publications, conference presentations and in-person or webinar presentations to community members and healthcare professionals.

Looking back at the lawsuit that transformed the chiropractic profession part 8: Judgment impact

OBJECTIVE

This paper is the eighth in a series that explores the historical events surrounding the Wilk v American Medical Association (AMA) lawsuit in which the plaintiffs argued that the AMA, the American Hospital Association, and other medical specialty societies violated antitrust law by restraining chiropractors' business practices. The purpose of this paper is to discuss the possible impact that the final decision in favor of the plaintiffs may have had on the chiropractic profession.

METHODS

This historical research study used a phenomenological approach to qualitative inquiry into the conflict between regular medicine and chiropractic and the events before, during, and after a legal dispute at the time of modernization of the chiropractic profession. Our methods included obtaining primary and secondary data sources. The final narrative recount was developed into 8 papers following a successive timeline. This paper is the eighth of the series that discusses how the trial decision may have influenced the chiropractic that we know today in the United States.

RESULTS

Chiropractic practice, education, and research have changed since before the lawsuit was filed. There are several areas in which we propose that the trial decision may have had an impact on the chiropractic profession.

CONCLUSION

The lawsuit removed the barriers that were implemented by organized medicine against the chiropractic profession. The quality of chiropractic practice, education, and research continues to improve and the profession continues to meet its most fundamental mission: to improve the lives of patients. Chiropractors practicing in the United States today are allowed to collaborate freely with other health professionals. Today, patients have the option to access chiropractic care because of the dedicated efforts of many people to reduce the previous barriers. It is up to the present-day members of the medical and chiropractic professions to look back and to remember what happened. By recalling the events surrounding the lawsuit, we may have a better understanding about our professions today. This information may help to facilitate interactions between medicine and chiropractic and to develop more respectful partnerships focused on creating a better future for the health of the public. The future of the chiropractic profession rests in the heads, hearts, and hands of its current members to do what is right.

The chiropractor's role in primary, secondary, and tertiary prevention of suicide: a clinical guide

OBJECTIVE

To provide the practicing chiropractor foundational knowledge to enhance the understanding of relevant primary, secondary, and tertiary public health measures for suicide prevention.

METHODS

A descriptive literature review was performed using keywords low back pain, neck pain, psychosocial, pain, public health, suicide, suicide risk factors, and suicide prevention. English language articles pertaining to suicide prevention and the chiropractic profession were retrieved and evaluated for relevance. Additional documents from the Centers for Disease Control, Veterans Health Administration, and the World Health Organization were reviewed. Key literature from the clinical social work and clinical psychology fields were provided by authorship team subject matter experts.

CONCLUSION

No articles reported a position statement regarding suicide prevention specific to the chiropractic profession. Risk, modifiable, and protective factors associated with self-directed violence are important clinical considerations. A proactive approach to managing patients at-risk includes developing interprofessional and collaborative relationships with mental health care professionals.

Doctors of chiropractic working with or within integrated healthcare delivery systems: a scoping review protocol

INTRODUCTION

Back and neck pain are the leading causes of disability worldwide. Doctors of chiropractic (DCs) are trained to manage these common conditions and can provide non-pharmacological treatment aligned with international clinical practice guidelines. Although DCs practice in over 90 countries, chiropractic care is rarely available within integrated healthcare delivery systems. A lack of DCs in private practice, particularly in low-income communities, may also limit access to chiropractic care. Improving collaboration between medical providers and community-based DCs, or embedding DCs in medical settings such as hospitals or community health centres, will improve access to evidence-based care for musculoskeletal conditions.

METHODS AND ANALYSES

This scoping review will map studies of DCs working with or within integrated healthcare delivery systems. We will use the recommended six-step approach for scoping reviews. We will search three electronic data bases including Medline, Embase and Web of Science. Two investigators will independently review all titles and abstracts to identify relevant records, screen the full-text articles of potentially admissible records, and systematically extract data from selected articles. We will include studies published in English from 1998 to 2020 describing medical settings that have established formal relationships with community-based DCs (eg, shared medical record) or where DCs practice in medical settings. Data extraction and reporting will be guided by the Proctor Conceptual Model for Implementation Research, which has three domains: clinical intervention, implementation strategies and outcome measurement. Stakeholders from diverse clinical fields will offer feedback on the implications of our findings via a web-based survey.

ETHICS AND DISSEMINATION

Ethics approval will not be obtained for this review of published and publicly accessible data, but will be obtained for the web-based survey. Our results will be disseminated through conference presentations and a peer-reviewed publication. Our findings will inform implementation strategies that support the adoption of chiropractic care within integrated healthcare delivery systems.
