The development and introduction of entrustable professional activities at 2 community-based chiropractic student preceptorship sites in the United States.

OBJECTIVE: Entrustable professional activities (EPAs) have seen widespread adoption in medical education and other health professions education. EPAs aim to provide a bridge between competency-based education and clinical practice by translating competencies into fundamental profession-specific tasks associated with clinical practice. Despite the extensive use of EPAs in health professions education, EPAs have yet to be introduced into chiropractic education. The purpose of this paper is to describe the development and introduction of EPAs as part of 2 community-based chiropractic student preceptorship education programs in the United States. METHODS: EPAs were developed and introduced at 2 community-based chiropractic preceptorship sites in 5 distinct steps: (1) differentiating EPAs from competencies, learning objectives, and knowledge, skills, and attitudes; (2) identifying EPAs; (3) mapping EPAs to competencies and necessary experience, knowledge, and skills; (4) designing EPA assessment strategies; and (5) implementing the use of EPAs. RESULTS: A total of 13 individual EPAs were developed and mapped to Council on Chiropractic Education meta-competency outcomes and underlying experience, knowledge, and skills. Three assessment tools were created to evaluate student entrustability for EPAs and enhance student self-assessment. The EPAs and assessment tools were integrated into chiropractic student preceptorships at each site. CONCLUSION: This paper describes the development and introduction of EPAs at 2 community-based chiropractic preceptorship sites. Future research is needed to develop and standardize EPA use and assessment, and to evaluate outcomes associated with EPA use.

Preoperative spinal education for lumbar spinal stenosis: A feasibility study.

INTRODUCTION: Lumbar spinal stenosis (LSS) is a leading cause of chronic musculoskeletal pain among older adults. A common and costly intervention for the treatment of LSS is lumbar decompression with or without fusion (LSS surgery), which has mixed outcomes among patients. Prehabilitation is a strategy designed to optimize the consistency of positive surgical outcomes and promote patient self-efficacy, while attempting to mitigate postoperative complications. No efforts have investigated the prehabilitation strategies specifically for patients undergoing LSS surgery. OBJECTIVE: To determine the feasibility of delivery and acceptability by participants of a novel prehabilitation intervention for patients undergoing LSS surgery. DESIGN: Feasibility study. SETTING: Outpatient orthopedic clinic at an academic medical center. PARTICIPANTS: Patients at least 50 years of age, who were scheduled for LSS surgery between October 2020 and October 2021. INTERVENTION: PreOperative Spinal Education for Lumbar Spinal Stenosis (POSE-LSS), is a novel multimodal, education-focused, time-efficient prehabilitation program for patients undergoing LSS surgery. Participants received the following: (1) Educational booklet and video; (2) In-person physical therapy (PT) session; and (3) Telemedicine visit with a physiatrist. MAIN OUTCOME MEASURE(S): The primary outcomes of interest were feasibility and acceptability of intervention by participants. Key potential surgical outcomes were length of stay and discharge disposition. RESULTS: POSE-LSS was completed by all eligible participants enrolled (n = 15) indicating feasibility and acceptability. Potential effectiveness measures including length of stay and discharge disposition were positively associated with the POSE-LSS intervention. CONCLUSIONS: This study demonstrates that a novel prehabilitation intervention is feasible, acceptable, and appears positively associated with important short-term measures of postoperative recovery that may impact the trajectory of patient care following LSS surgery.

Attitudes, beliefs, and recommendations for persistent low back pain patients: cross-sectional surveys of students and faculty at a chiropractic college.

BACKGROUND: While the use of chiropractic care for persistent low back pain (PLBP) is prevalent, chiropractors' attitudes and beliefs related to PLBP patients are not fully understood. The purpose of this study was to assess the attitudes, beliefs and activity/work recommendations of students and faculty at a chiropractic college regarding PLBP patients. METHODS: The Health Care Providers Pain and Impairment Relationship Scale (HC-PAIRS) and clinical vignettes were requested to be completed by chiropractic students and faculty at Parker University in April 2018. Higher HC-PAIRS scores indicate stronger beliefs that PLBP justifies disability and limitation of activities. Activity and work recommendations from clinical vignettes were rated as "adequate", "neutral", or "inadequate", as defined in previous literature. Descriptive statistics, independent t-tests, and logistic regression were used to analyze results. RESULTS: Student and faculty response rates were 63.6% and 25.9%, respectively. Faculty mean HC-PAIRS scores (3.66 [SD:0.88]) were significantly lower than students' (4.41 [SD:0.71]). The percentage of faculty providing "adequate" activity (62.1%) and work (41.0%) recommendations was significantly greater than the percentage of students (activity: 33.9%, work: 21.2%) (p < 0.05). Higher HC-PAIRS scores in students were associated with decreased odds of providing "adequate" activity and work recommendations. CONCLUSIONS: Student and faculty attitudes and beliefs, and students' activity/work recommendations were found to be dissimilar to those from similar studies and less congruent with CPG recommendations. Lower HC-PAIRS scores increased the odds of students providing "adequate" activity and work recommendations to patients with PLBP. Results from this study may help guide future research and training opportunities.

Association between spinal manipulative therapy and lumbar spine reoperation after discectomy: a retrospective cohort study.

BACKGROUND: Patients who undergo lumbar discectomy may experience ongoing lumbosacral radiculopathy (LSR) and seek spinal manipulative therapy (SMT) to manage these symptoms. We hypothesized that adults receiving SMT for LSR at least one year following lumbar discectomy would be less likely to undergo lumbar spine reoperation compared to matched controls not receiving SMT, over two years' follow-up. METHODS: We searched a United States network of health records (TriNetX, Inc.) for adults aged ≥ 18 years with LSR and lumbar discectomy ≥ 1 year previous, without lumbar fusion or instrumentation, from 2003 to 2023. We divided patients into two cohorts: (1) chiropractic SMT, and (2) usual care without chiropractic SMT. We used propensity matching to adjust for confounding variables associated with lumbar spine reoperation (e.g., age, body mass index, nicotine dependence), calculated risk ratios (RR), with 95% confidence intervals (CIs), and explored cumulative incidence of reoperation and the number of SMT follow-up visits. RESULTS: Following propensity matching there were 378 patients per cohort (mean age 61 years). Lumbar spine reoperation was less frequent in the SMT cohort compared to the usual care cohort (SMT: 7%; usual care: 13%), yielding an RR (95% CIs) of 0.55 (0.35-0.85; P = 0.0062). In the SMT cohort, 72% of patients had ≥ 1 follow-up SMT visit (median = 6). CONCLUSIONS: This study found that adults experiencing LSR at least one year after lumbar discectomy who received SMT were less likely to undergo lumbar spine reoperation compared to matched controls not receiving SMT. While these findings hold promise for clinical implications, they should be corroborated by a prospective study including measures of pain, disability, and safety to confirm their relevance. We cannot exclude the possibility that our results stem from a generalized effect of engaging with a non-surgical clinician, a factor that may extend to related contexts such as physical therapy or acupuncture.

Assessment of back pain behaviors, attitudes, and beliefs of chiropractic research conference attendees after a biopsychosocial educational workshop.

OBJECTIVE: The purpose of this study was to assess the behaviors, attitudes, and beliefs of attendees of a chiropractic research conference (which included chiropractic students, clinicians, researchers, and educators) toward chronic low back pain (CLBP) before and after a biopsychosocial (BPS)-based CLBP educational workshop. METHODS: This single-arm intervention study used the Health Care Providers' Pain and Relationship Scale (HC-PAIRS) and CLBP-related clinic vignettes to assess behaviors, attitudes, and beliefs toward CLBP before and after a single 90-minute educational workshop. The HC-PAIRS is a self-reporting questionnaire that consists of 15 items rated on a 7-point rating scale, with a higher score suggesting a belief that pain is linked to movement and that recommendations should be given to avoid physical activities. RESULTS: The pre-education intervention HC-PAIRS and vignettes were completed by 40 of 56 attendees. A total of 18 participants completed the posteducation intervention HC-PAIRS and CLBP-related clinical vignettes. Most of participants identified as full-time clinicians, employees of the United States Department of Veterans Affairs, and musculoskeletal/neuromusculoskeletal providers. The pre-education intervention HC-PAIRS mean score was 44.8 (SD 9.22), and the postscore was 39.5 (SD 6.49). CONCLUSION: Findings suggest an immediate change in HC-PAIRS scores following a BPS-focused CLBP education intervention for a chiropractic audience. However, due to limitations related to sample size and target population, findings should be interpreted cautiously.

Associations between demographics and clinical ideology, beliefs, and practice patterns: a secondary analysis of a survey of randomly sampled United States chiropractors.

BACKGROUND: The chiropractic profession in the United States (US) has a long history of intra-professional discourse surrounding ideology and beliefs. Large-scale efforts have evaluated 3 distinctive subgroups of US chiropractors focused on these areas of practice: spine/neuromusculoskeletal, primary care, and vertebral subluxation. To our knowledge, there have not been any prior studies exploring the factors associated with these ideology and belief characteristics of these subgroups. The purpose of this study was to explore, describe, and characterize the association of US chiropractors' ideology, beliefs, and practice patterns with: 1) chiropractic degree program of graduation, 2) years since completion of chiropractic degree, and 3) US geographic region of primary practice. METHODS: This was a secondary analysis of a cross-sectional survey of a random sample of US licensed chiropractors (n = 8975). A 10% random sample was extracted from each of the 50 states and District of Columbia chiropractic regulatory board lists. The survey was conducted between March 2018-January 2020. The survey instrument consisted of 7 items that were developed to elicit these differentiating ideologies, beliefs, and practice patterns: 1) clinical examination/assessment, 2) health conditions treated, 3) role of chiropractors in the healthcare system, 4) the impact of chiropractic adjustments [spinal manipulation] in treating patients with cancer, 5) vaccination attitudes, 6) detection of subluxation on x-ray, and 7) x-ray utilization rates. Multinomial regression was used to analyze associations between these 7 ideology and practice characteristic items from the survey (dependent variables) and the 3 demographic items listed above (independent variables). RESULTS: Data from 3538 respondents (74.6% male) were collected with an overall response rate of 39.4%. Patterns of responses to the 7 survey items for ideologies, beliefs, and practice characteristics were significantly different based on chiropractic degree program of graduation, years since completion of chiropractic degree, and geographic region of primary practice. CONCLUSIONS: Among US chiropractors, chiropractic program of graduation, years since completion of chiropractic degree, and geographic region of primary practice are associated with variations in clinical ideology, beliefs, and practice patterns. The wide variation and inconsistent beliefs of US chiropractors could result in public confusion and impede interprofessional integration.

More Problems, More Pain: The Role of Chronic Life Stressors and Racial/Ethnic Identity on Chronic Pain Among Middle-Aged and Older Adults in the United States.

There is a high prevalence of chronic pain among middle-aged and older adults in the United States. Chronic life stressors have been shown to have detrimental consequences for myriad health conditions, including chronic pain. However, there is limited evidence on the types of chronic life stressors that affect middle-aged and older adults and how these stressors influence the chronic pain burden in this population. Moreover, the interaction between chronic life stressors and racial/ethnic identity remains poorly understood as it relates to chronic pain. The current analysis used the 2018 Health and Retirement Study to investigate relationships between chronic life stressors and odds to experience any chronic pain and high-impact chronic pain. Chronic life stressors were characterized, overall and by racial/ethnic identity, and the main and interaction effects were calculated to evaluate relationships between chronic life stressors, racial/ethnic identity, and odds of experiencing any chronic pain and high-impact chronic pain. Results indicate that in 2018, the most common chronic life stressor among middle-aged and older adults was dealing with their own health problems (68%), followed by dealing with the physical or emotional issues affecting a spouse or child (46%). Adjusted analyses showed that a higher total of chronic life stressors increased the odds of middle-aged and older adults experiencing any chronic pain and high-impact chronic pain. There were no significant interactions between the overall chronic life stress burden and racial/ethnic identity as a predictor of odds to experience any chronic pain or high-impact chronic pain, but significant interaction effects were found related to specific chronic life stressors. Findings underscore the significant impact of chronic life stressors on the chronic pain burden among middle-aged and older adults in the United States, which cut across racial/ethnic identity.

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.

Trials Informing Back Pain Guidelines Underreport Key Sociodemographic Data.

INTRODUCTION: Sociodemographic characteristics are related to low back pain (LBP) outcomes, therefore diverse representation is important when appraising clinical trials. We investigated the reporting of participant sociodemographic variables in trials informing the American College of Physicians (ACP) guidelines for the treatment of LBP. METHODS: Clinical trials supporting recommended interventions in the ACP guidelines were reviewed for reporting of participant sociodemographic data. RESULTS: Of 116 trials, 34 reported participant race and/or ethnicity. Education level, income level, and employment status were reported in 24, 10, and 31 trials, respectively; insurance coverage, marital status, and religion were reported in three, 16, and two trials, respectively. Two trials reported on duration or location of residence. Language comprehension was the most frequent exclusion criterion. CONCLUSIONS: Insufficient sociodemographic data exist in trials informing the ACP guidelines for the treatment of LBP. Investigators of LBP interventions should recruit diverse study participants and report comprehensive sociodemographic data.

A Description of Theoretical Models for Health Service Utilization: A Scoping Review of the Literature.

Theoretical models to explain health service utilization are numerous and there is no known literature that has synthesized existing models for health service utilization. Systematic searches were conducted in PubMed, MEDLINE, PsychINFO, Scopus, and CINAHL databases from 1960 through May 2021. Literature theorizing models/frameworks for health service utilization were included. Multiple investigators screened citations and full texts. Data extracted included: (1) citation information, (2) purpose of models, and (3) major constructs of models. The search retrieved 6639 citations. A total of 34 articles were eligible for this review. Theoretical models were categorized into 4 thematic domains based on the purpose of the model: (1) generalized health service utilization, (2) health service utilization with respect to specific sociodemographic determinants of health, (3) health service utilization specific to illness or health disciplines, and (4) preventive health services/screenings. There was an increase in models developed over time with a trend toward model development specific to sociodemographic determinants of health, illness, and/or health disciplines. This review cataloged theoretical models for health service utilization by thematic domain to enhance the identification and critical review of existing models. Findings support the notion that theoretical pluralism has been adopted in the field of health service utilization.

A narrative review of social determinants of health education in health professional programs and potential pathways for integration into Doctor of Chiropractic programs.

Objectives: To conduct a narrative review of the literature pertaining to strategies employed by health professional programs to teach social determinants of health (SDOH) and use the results to describe pathways for integrating SDOH education into Doctor of Chiropractic programs (DCPs). Methods: A narrative review of peer-reviewed literature describing SDOH education in health professional programs within the United States was performed. The results were used to inform potential pathways of integrating SDOH education into all aspects of DCPs. Results: Twenty-eight papers demonstrated health professional programs' incorporation of SDOH education and assessment into didactic and experiential learning opportunities. Educational interventions resulted in positive changes in knowledge and attitudes toward SDOH. Conclusion: This review demonstrates existing methods for integrating SDOH in health professional programs. Methods may be adopted and assimilated into an existing DCP. Further research is needed to understand barriers and facilitators to the implementation of SDOH education into DCPs.

Objectifs: Réaliser une analyse narrative de la littérature relative aux stratégies employées par les programmes de professionnels de la santé pour enseigner les déterminants sociaux de la santé (DSS) et utiliser les résultats pour décrire les voies d'intégration de l'enseignement des DSS dans les programmes de doctorat en chiropratique (PDC). Méthodes: Une analyse narrative de la documentation évaluée par les pairs décrivant l'enseignement des déterminants sociaux de la santé dans les programmes de formation des professionnels de la santé aux États-Unis a été réalisée. Les résultats ont été utilisés pour éclairer les voies potentielles d'intégration de l'enseignement des DSS dans tous les aspects des PDC. Résultats: Vingt-huit articles ont fait état de l'intégration, par les programmes de professionnels de la santé, de l'enseignement et de l'évaluation des DSS dans les possibilités d'apprentissage didactique et expérientiel. Les interventions éducatives ont entraîné des changements positifs dans les connaissances et les attitudes à l'égard des DSS. Conclusion: Cette étude présente les méthodes existantes d'intégration des DSS dans les programmes de formation des professionnels de la santé. Ces méthodes peuvent être adoptées et assimilées dans un PDC existant. D'autres recherches sont nécessaires pour comprendre les obstacles et les facilitateurs de la mise en oeuvre de l'enseignement des DSS dans les PDC.

Disparities in chiropractic utilization by race, ethnicity and socioeconomic status: A scoping review of the literature.

BACKGROUND: Chiropractic is the largest complementary and alternative medicine profession in the United States, with increasing global growth. A preliminary literature review suggests a lack of widespread diversity of chiropractic patient profiles. OBJECTIVE: There have been no prior studies to comprehensively integrate the literature on chiropractic utilization rates by race, ethnicity, and socioeconomic status. The purpose of this scoping review is to identify and describe the current state of knowledge of chiropractic utilization by race, ethnicity, education level, employment status, and income and poverty level. SEARCH STRATEGY: Systematic searches were conducted in PubMed, Ovid MEDLINE, Cumulative Index of Nursing and Allied Health Literature (CINAHL), Cochrane Database of Systematic Reviews, and Index to Chiropractic Literature from inception to May 2021. INCLUSION CRITERIA: Articles that reported race or ethnicity, education level, employment status, income or poverty level variables and chiropractic utilization rates for adults (≥18 years of age) were eligible for this review. DATA EXTRACTION AND ANALYSIS: Data extracted from articles were citation information, patient characteristics, race and ethnicity, education level, employment status, income and poverty level, and chiropractic utilization rate. A descriptive numerical summary of included studies is provided. This study provides a qualitative thematic narrative of chiropractic utilization with attention to race and ethnicity, education level, income and poverty level, and employment status. RESULTS: A total of 69 articles were eligible for review. Most articles were published since 2003 and reported data from study populations in the United States. Of the race, ethnicity and socioeconomic categories that were most commonly reported, chiropractic utilization was the highest for individuals identifying as European American/White/non-Hispanic White/Caucasian (median 20.00%; interquartile range 2.70%-64.60%), those with employment as a main income source (median utilization 78.50%; interquartile range 77.90%-79.10%), individuals with an individual or household/family annual income between $40,001 and $60,000 (median utilization 29.40%; interquartile range 25.15%-33.65%), and individuals with less than or equal to (12 years) high school diploma/general educational development certificate completion (median utilization 30.70%; interquartile range 15.10%-37.00%). CONCLUSION: This comprehensive review of the literature on chiropractic utilization by race, ethnicity and socioeconomic status indicates differences in chiropractic utilization across diverse racial and ethnic and socioeconomic populations. Heterogeneity existed among definitions of key variables, including race, ethnicity, education level, employment status, and income and poverty level in the included studies, reducing clarity in rates of chiropractic utilization for these populations.

Manual therapy interventions in the management of adults with prior cervical spine surgery for degenerative conditions: a scoping review.

OBJECTIVE: Cervical spine surgeries for degenerative conditions are rapidly increasing. Cervical post-surgery syndrome consisting of chronic pain, adjacent segment disease, recurrent disc herniation, facet joint pain, and/or epidural scarring is common. Repeat surgery is regularly recommended, though patients are often unable to undergo or decline further surgery. Manual therapy is included in clinical practice guidelines for neck pain and related disorders, however clinical guidance for utilization of manual therapy in adults with prior cervical spine surgery is lacking. This study aimed to synthesize available literature and characterize outcomes and adverse events for manual therapy interventions in adults with prior cervical spine surgery due to degenerative conditions. METHODS: Preferred reporting items for systematic reviews and meta-analyses extension for scoping reviews was followed. PubMed, Cumulative Index of Nursing and Allied Health Literature, physiotherapy evidence database, and Index to Chiropractic Literature were searched from inception through October 2021. English-language literature comprised of randomized clinical trials (RCT), case-control, cohort, and case report designs were included. Adults undergoing manual therapy, with or without combination of other interventions, with prior cervical spine surgery due to degenerative conditions were included. RESULTS: Twelve articles were identified, including 10 case reports, 1 low-quality RCT, and 1 acceptable-quality RCT. Eight case reports described 9 patients with history of fusion surgery. Two case reports described 2 patients with history of discectomy. One case report described one patient with separate operations of a discectomy at one level and a fusion at another level. One case report described 2 patients with history of cervical disc replacement surgery. The two RCTs included 63 and 86 participants, respectively. Use of manual joint mobilization/manipulation, table/instrument assisted mobilization/manipulation, and multimodal interventions were described in eligible studies. Favorable clinical outcomes were reported in 10 studies. Six case reports/series involving 8 patients described use of unclassified forms of manual therapy. Eight studies described the use of multimodal interventions along with manual therapy. One study described high patient satisfaction. Two studies, accounting for 3 patients, reported serious adverse events. CONCLUSIONS: There is a lack of literature informing evidence related to clinical outcomes, patient satisfaction, and adverse events associated with manual therapy for patients with prior cervical spine surgery due to degenerative conditions. High-quality studies of higher-level hierarchical study design are needed to understand the clinical utility and safety profile of manual therapy for this population.

Case 298: Skeletal Fluorosis Secondary to Huffing.

History A 37-year-old man from the United States presented with a 1-year history of neck pain and stiffness that had been unsuccessfully treated with manipulative therapy by a chiropractor at another institution. Past medical history was remarkable only for marijuana and air duster abuse. He denied use of any prescription medications. Physical examination was notable for markedly reduced range of motion of the cervical spine. Laboratory work-up revealed an elevated alkaline phosphatase level (302 U/L [5.0 µkat/L]; normal range, 40-100 U/L [0.7-1.67 µkat/L]), but all other laboratory findings, including complete blood count, renal function, liver function, vitamin A level, serum protein electrophoresis, and hepatitis C antibodies were within normal limits. Cervical spine radiography was performed, followed by MRI. Subsequently, a full skeletal survey was ordered. Included are representative radiographs of the pelvis, left forearm, and distal right leg with ankle.

Evaluation of United States chiropractic professional subgroups: a survey of randomly sampled chiropractors.

BACKGROUND: Professional subgroups are common and may play a role in aiding professional maturity or impeding professional legitimization. The chiropractic profession in the United States has a long history of diverse intra-professional subgroups with varying ideologies and practice styles. To our knowledge, large-scale quantification of chiropractic professional subgroups in the United States has not been conducted. The purpose of this study was to quantify and describe the clinical practice beliefs and behaviors associated with United States chiropractic subgroups. METHODS: A 10% random sample of United States licensed chiropractors (n = 8975) was selected from all 50 state regulatory board lists and invited to participate in a survey. The survey consisted of a 7-item questionnaire; 6 items were associated with chiropractic ideological and practice characteristics and 1 item was related to the self-identified role of chiropractic in the healthcare system which was utilized as the dependent variable to identify chiropractic subgroups. Multinomial logistic regression with predictive margins was used to analyze which responses to the 6 ideology and practice characteristic items were predictive of chiropractic subgroups. RESULTS: A total of 3538 responses were collected (39.4% response rate). Respondents self-identified into three distinct subgroups based on the perceived role of the chiropractic profession in the greater healthcare system: 56.8% were spine/neuromusculoskeletal focused; 22.0% were primary care focused; and 21.2% were vertebral subluxation focused. Patterns of responses to the 6 ideologies and practice characteristic items were substantially different across the three professional subgroups. CONCLUSIONS: Respondents self-identified into one of three distinct intra-professional subgroups. These subgroups can be differentiated along themes related to clinical practice beliefs and behaviors.

Case 298.

History A 37-year-old man from the United States presented with a 1-year history of neck pain and stiffness that had been unsuccessfully treated with manipulative therapy by a chiropractor at another institution. Past medical history was remarkable only for marijuana and air duster abuse. He denied use of any prescription medications. Physical examination was notable for markedly reduced range of motion of the cervical spine. Laboratory work-up revealed an elevated alkaline phosphatase level (302 U/L [5.0 µkat/L]; normal range, 40-100 U/L [0.7-1.67 µkat/L]), but all other laboratory findings, including complete blood count, renal function, liver function, vitamin A level, serum protein electrophoresis, and hepatitis C antibodies were within normal limits. Cervical spine radiography was performed (Fig 1), followed by MRI (Fig 2). Subsequently, a full skeletal survey was ordered. Included are representative radiographs of the pelvis (Fig 3), left forearm (Fig 4), and distal right leg with ankle (Fig 5).

Spinal manipulative therapy and cervical artery dissection: A retrospective comparison with spontaneous, traumatic, and iatrogenic etiologies at a single academic medical center.

OBJECTIVE: Cervical artery dissection (CAD) has been associated with spinal manipulative therapy (SMT). Although uncommonly reported, SMT-associated CADs hold devastating neurological consequences, warranting further exploration. We endeavored to investigate this association through the comparison of all CAD etiologies at a single academic medical center. METHODS: A retrospective chart review was conducted of patients diagnosed with CAD or transferred to our institution for primary management of CAD during the 10-year period from 2010 to 2020 (n = 578). Patients were divided into SMT-associated (within 1 month of presentation), spontaneous, traumatic, and iatrogenic cohorts. RESULTS: SMT-associated dissections represented 23/578 (4%) of all dissections and 5.9% of vertebral artery dissections specifically. These patients were generally younger than those in the spontaneous (p = .004) and iatrogenic groups (p < .001), and more often non-smokers or former smokers compared to the spontaneous (p = .009), traumatic (p = .001), and iatrogenic (p = .008) groups. Additionally, the SMT group had a higher mean low-density lipoprotein (LDL) than the spontaneous (p = .009) and traumatic (p = .003) types. SMT-associated CADs were more often vertebral and bilateral, compared to the spontaneous (p = .003; p < .001), traumatic (p = .047; p = .004), and iatrogenic (p = .002; p = .002) groups. Outcomes including infarct (p = .112), medical treatment (p = .523), intervention (p = .47), and length of stay (p = .512) were similar between the SMT and spontaneous groups. CONCLUSIONS: In this unique study comparing SMT-associated CADs with other dissection etiologies, SMT-associated CADs were uncommon and not associated with worse clinical outcomes. However, SMT-associated CADs were more likely to be bilateral and affected the vertebral arteries in young, non-smoking patients with high LDL.

Non-Surgical Interventions for Lumbar Spinal Stenosis Leading To Neurogenic Claudication: A Clinical Practice Guideline.

Lumbar spinal stenosis (LSS) causing neurogenic claudication (NC) is increasingly common with an aging population and can be associated with significant symptoms and functional limitations. We developed this guideline to present the evidence and provide clinical recommendations on nonsurgical management of patients with LSS causing NC. Using the GRADE approach, a multidisciplinary guidelines panel based recommendations on evidence from a systematic review of randomized controlled trials and systematic reviews published through June 2019, or expert consensus. The literature monitored up to October 2020. Clinical outcomes evaluated included pain, disability, quality of life, and walking capacity. The target audience for this guideline includes all clinicians, and the target patient population includes adults with LSS (congenital and/or acquired, lateral recess or central canal, with or without low back pain, with or without spondylolisthesis) causing NC. The guidelines panel developed 6 recommendations based on randomized controlled trials and 5 others based on professional consensus, summarized in 3 overarching recommendations: (Grade: statements are all conditional/weak recommendations) Recommendation 1. For patients with LSS causing NC, clinicians and patients may initially select multimodal care nonpharmacological therapies with education, advice and lifestyle changes, behavioral change techniques in conjunction with home exercise, manual therapy, and/or rehabilitation (moderate-quality evidence), traditional acupuncture on a trial basis (very low-quality evidence), and postoperative rehabilitation (supervised program of exercises and/or educational materials encouraging activity) with cognitive-behavioral therapy 12 weeks postsurgery (low-quality evidence). Recommendation 2. In patients LSS causing NC, clinicians and patients may consider a trial of serotonin-norepinephrine reuptake inhibitors or tricyclic antidepressants. (very low-quality evidence). Recommendation 3. For patients LSS causing NC, we recommend against the use of the following pharmacological therapies: nonsteroidal anti-inflammatory drugs, methylcobalamin, calcitonin, paracetamol, opioids, muscle relaxants, pregabalin (consensus-based), gabapentin (very low-quality), and epidural steroidal injections (high-quality evidence). PERSPECTIVE: This guideline, on the basis of a systematic review of the evidence on the nonsurgical management of lumbar spine stenosis, provides recommendations developed by a multidisciplinary expert panel. Safe and effective non-surgical management of lumbar spine stenosis should be on the basis of a plan of care tailored to the individual and the type of treatment involved, and multimodal care is recommended in most situations.

The Relationship Between Patient Satisfaction and Healthcare Expenditures in Adults with Spine Related Disorders: An Analysis of the 2008 to 2015 Medical Expenditures Panel Survey (MEPS).

STUDY DESIGN: Cross-sectional study. OBJECTIVE: The aim of this study was to investigate the relationship between patient satisfaction (PS) and healthcare expenditures (HCE) in adults with spine related disorders (SRDs). SUMMARY OF BACKGROUND DATA: SRDs are widespread and pose a high cost to society. PS and HCE have yet to be studied in this population. METHODS: Fifteen thousand eight hundred fifty adults with SRDs from the Medical Expenditures Panel Survey (MEPS) (2008-2015) were analyzed. The MEPS medical conditions files were used to identify SRDs based on International Classification of Diseases-9 codes. Frequencies and percentages of sample demographics were calculated. HCE was measured as total direct payments for care provided during the survey year. A composite PS score was constructed using a 0 to 10 rating of their healthcare providers combined with the frequency in which patients felt they were listened to, were given understandable explanations, were respected, and were given enough time. Mean unadjusted HCE were calculated for each year and by quartile of PS. A two-part model consisting of a probit model and subsequent generalized linear model with gamma distribution was performed, adjusting for relevant covariates. Margins command was used to calculate incremental estimates of HCE. RESULTS: Mean unadjusted HCE increased annually from $7057 (95% confidence interval [CI], $6516, $7597) in 2008 to $9820 (95% CI, $8811, $10,830) in 2015 for adults with SRDs. Adjusting for predisposing factors, individuals in second, third, and fourth quartiles of PS were significantly different from the first quartile. Adjusting for predisposing and enabling factors, only fourth quartile was significantly different from first quartile. After adjusting for predisposing, enabling and need factors, second, third, and fourth quartiles were no longer significantly different from the first quartile. CONCLUSION: Expenditures have increased over time in adults with SRDs. PS is significantly associated with expenditures after controlling for predisposing and enabling factors, but not significant after controlling for need factors. Need factors appear to explain the relationship between lower levels of PS and higher HCE in adults with SRDs.Level of Evidence: 2.
