Patient-reported pain and physical health for acupuncture and chiropractic care delivered by Veterans Affairs versus community providers.

BACKGROUND: Acupuncture and chiropractic care are evidence-based pain management alternatives to opioids. The Veterans Health Administration (VA) provides this care in some VA facilities, but also refers patients to community providers. We aimed to determine if patient-reported outcomes differ for acupuncture and chiropractic care from VA versus community providers. MATERIALS AND METHODS: We conducted an observational study using survey outcome data and electronic medical record utilization data for acupuncture and chiropractic care provided in 18 VA facilities or in community facilities reimbursed by VA. Study participants were users of VA primary care, mental health, pain clinic, complementary and integrative therapies, coaching or education services in 2018-2019. Patients received 1) 4+ acupuncture visits (N = 201) or 4+ chiropractic care visits (N = 178) from a VA or community provider from 60 days prior to baseline to six-months survey and 2) no acupuncture or chiropractic visits from 1 year to 60 days prior to baseline. Outcomes measured included patient-reported pain (PEG) and physical health (PROMIS) at baseline and six-month surveys. Multivariate analyses examined outcomes at six months, adjusting for baseline outcomes and demographics. RESULTS: In unadjusted analyses, pain and physical health improved for patients receiving community-based acupuncture, while VA-based acupuncture patients experienced no change. Unadjusted analyses also showed improvements in physical health, but not pain, for patients receiving VA-based chiropractic care, with no changes for community-based chiropractic care patients. Using multivariate models, VA-based acupuncture was no different from community-based acupuncture for pain (-0.258, p = 0.172) or physical health (0.539, p = 0.399). Similarly, there were no differences between VA- and community-based chiropractic care in pain (-0.273, p = 0.154) or physical health (0.793, p = 0.191). CONCLUSIONS: Acupuncture and chiropractic care were associated with modest improvements at six months, with no meaningful differences between VA and community providers. The choice to receive care from VA or community providers could be based on factors other than quality, like cost or convenience.

How well do participants in clinical trials represent the U.S. population with chronic neck or back pain?

BACKGROUND: Randomized clinical trials (RCTs) are the gold standard for assessing treatment effectiveness; however, they have been criticized for generalizability issues such as how well trial participants represent those who receive the treatments in clinical practice. We assessed the representativeness of participants from eight RCTs for chronic spine pain in the U.S., which were used for an individual participant data meta-analysis on the cost-effectiveness of spinal manipulation for spine pain. In these clinical trials, spinal manipulation was performed by chiropractors. METHODS: We conducted a retrospective secondary analysis of RCT data to compare trial participants' socio-demographic characteristics, clinical features, and health outcomes to a representative sample of (a) U.S. adults with chronic spine pain and (b) U.S. adults with chronic spine pain receiving chiropractic care, using secondary data from the National Health Interview Survey (NHIS) and Medical Expenditure Panel Survey (MEPS). We assessed differences between trial and U.S. spine populations using independent t-tests for means and z-tests for proportions, accounting for the complex multi-stage survey design of the NHIS and MEPS. RESULTS: We found the clinical trials had an under-representation of individuals from health disparity populations with lower percentages of racial and ethnic minority groups (Black/African American 7% lower, Hispanic 8% lower), less educated (No high school degree 19% lower, high school degree 11% lower), and unemployed adults (25% lower) with worse health outcomes (physical health scores 2.5 lower and mental health scores 5.3 lower using the SF-12/36) relative to the U.S. population with spine pain. While the odds of chiropractic use in the U.S. are lower for individuals from health disparity populations, the trials also under-represented these populations relative to U.S. adults with chronic spine pain who visit a chiropractor. CONCLUSIONS: Health disparity populations are not well represented in spine pain clinical trials. Embracing key community-based approaches, which have shown promise for increasing participation of underserved communities, is needed.

Chiropractic spinal manipulation and likelihood of tramadol prescription in adults with radicular low back pain: a retrospective cohort study using US data.

OBJECTIVES: Patients receiving chiropractic spinal manipulation (CSM) for low back pain (LBP) are less likely to receive any opioid prescription for subsequent pain management. However, the likelihood of specifically being prescribed tramadol, a less potent opioid, has not been explored. We hypothesised that adults receiving CSM for newly diagnosed radicular LBP would be less likely to receive a tramadol prescription over 1-year follow-up, compared with those receiving usual medical care. DESIGN: Retrospective cohort study. SETTING: US medical records-based dataset including >115 million patients attending academic health centres (TriNetX, Inc), queried 9 November 2023. PARTICIPANTS: Opioid-naive adults aged 18-50 with a new diagnosis of radicular LBP were included. Patients with serious pathology and tramadol use contraindications were excluded. Variables associated with tramadol prescription were controlled via propensity matching. INTERVENTIONS: Patients were divided into two cohorts dependent on treatment received on the index date of radicular LBP diagnosis (CSM or usual medical care). PRIMARY AND SECONDARY OUTCOME MEASURES: Risk ratio (RR) for tramadol prescription (primary); markers of usual medical care utilisation (secondary). RESULTS: After propensity matching, there were 1171 patients per cohort (mean age 35 years). Tramadol prescription was significantly lower in the CSM cohort compared with the usual medical care cohort, with an RR (95% CI) of 0.32 (0.18 to 0.57; p<0.0001). A cumulative incidence graph demonstrated that the reduced incidence of tramadol prescription in the CSM cohort relative to the usual medical care cohort was maintained throughout 1-year follow-up. Utilisation of NSAIDs, physical therapy evaluation and lumbar imaging was similar between cohorts. CONCLUSIONS: This study found that US adults initially receiving CSM for radicular LBP had a reduced likelihood of receiving a tramadol prescription over 1-year follow-up. These findings should be corroborated by a prospective study to minimise residual confounding.

Direct medical costs after surgical or nonsurgical treatment for degenerative lumbar spinal disease: A nationwide matched cohort study with a 10-year follow-up.

OBJECTIVE: The demand for treating degenerative lumbar spinal disease has been increasing, leading to increased utilization of medical resources. Thus, we need to understand how the budget of insurance is currently used. The objective of the present study is to overview the utilization of the National Health Insurance Service (NHIS) by providing the direct insured cost between patients receiving surgery and patients receiving nonsurgical treatment for degenerative lumbar disease. METHODS: The NHIS-National Sample Cohort was utilized to select patients with lumbar disc herniation, spinal stenosis, spondylolisthesis or spondylolysis. A matched cohort study design was used to show direct medical costs of surgery (n = 2,698) and nonsurgical (n = 2,698) cohorts. Non-surgical treatment included medication, physiotherapy, injection, and chiropractic. The monthly costs of the surgery cohort and nonsurgical cohort were presented at initial treatment, posttreatment 1, 3, 6, 9, and 12 months and yearly thereafter for 10 years. RESULTS: The characteristics and matching factors were well-balanced between the matched cohorts. Overall, surgery cohort spent $50.84/patient/month, while the nonsurgical cohort spent $29.34/patient/month (p<0.01). Initially, surgery treatment led to more charge to NHIS ($2,762) than nonsurgical treatment ($180.4) (p<0.01). Compared with the non-surgical cohort, the surgery cohort charged $33/month more for the first 3 months, charged less at 12 months, and charged approximately the same over the course of 10 years. CONCLUSION: Surgical treatment initially led to more government reimbursement than nonsurgical treatment, but the charges during follow-up period were not different. The results of the present study should be interpreted in light of the costs of medical services, indirect costs, societal cost, quality of life and societal willingness to pay in each country. The monetary figures are implied to be actual economic costs but those in the reimbursement system instead reflect reimbursement charges from the government.

Chiropractic Practice in the Continent of Africa: A Structured Online Survey of 608 Chiropractors.

OBJECTIVES: The purpose of this study was to assess the status, supply, demographics, and characteristics of chiropractic practice in the continent of Africa. METHODS: A survey consisting of questions on demographics, clinical practice, and patient profile was administered to 608 chiropractors practicing in the different countries of the African continent. Chiropractic association officers of each country were contacted via e-mail for assistance in the distribution of the survey link to chiropractors in their country. The initial questionnaire was pretested with a small group of chiropractors from 2 African countries-4 from Ethiopia and 6 from Botswana-to assess the validity of the questions. The legal status of the chiropractic practice was obtained from online resources. Descriptive statistics were conducted in Microsoft Excel. RESULTS: Of the 54 countries in the continent of Africa, 23 countries were identified to have chiropractors. One hundred twenty-four surveys were returned from 15 countries with an overall response rate of 20.3% by clinicians with varying years in clinical practice. Nearly 84% of the chiropractors were between ages 26 and 50. More than 69% reported being a graduate of 1 of the 2 academic institutions located in Africa. Most chiropractors practice in South Africa. Most chiropractors practice in privately owned clinics, and 38% practice in multidisciplinary clinics. Nearly 92% reported using diversified technique and 27% used McKenzie exercises for treatment. Patients presented with a variety of conditions, predominantly chronic pain (59%). CONCLUSIONS: This study provides a general overview on the status, supply, demographics, and characteristics of chiropractic practice in the continent of Africa. The supply of chiropractors in Africa is scarce and unevenly distributed. Although in the early stages of recognition, chiropractors in Africa are contributing to the care of people with musculoskeletal and spine-related disorders. Considering the high burden of spine pain, there appears to be potential for growth for chiropractic in the continent of Africa.

Assessing Adverse Events After Chiropractic Care at a Chiropractic Teaching Clinic: An Active-Surveillance Pilot Study.

OBJECTIVE: This study aimed to assess the feasibility of implementing an active-surveillance reporting system within a chiropractic teaching clinic and subsequently determining the frequency of adverse events (AEs) after treatment administered by chiropractic interns. METHODS: Interns were invited to collect data from patients using 3 questionnaires that recorded patient symptom change: 2 completed by the patient (before and 7 days after treatment) and 1 completed by the intern (immediately after treatment). Worsened and new symptoms were considered AEs. Qualitative interviews were conducted with clinicians and interns to assess the feasibility of implementing the reporting system, with resulting data categorized under 4 domains: acceptability, implementation, practicality, and integration. RESULTS: Of the 174 eligible interns, 80 (46.0%) collected data from 364 patient encounters, with 119 (32.7%) returning their posttreatment form. Of the 89 unique patients (mean age = 39.5 years; 58.4% female, 41.6% male), 40.1% presented with low back pain and 31.1% with neck pain. After treatment, 25 symptoms (8.9%) were identified as AEs, mostly reported by patients as worsening discomfort or pain. Data from qualitative interviews suggest that the AE reporting system was well accepted; however, proposed specific modifications include use of longitudinal electronic surveys. CONCLUSION: Our findings suggest that it is feasible to conduct an active-surveillance reporting system at a chiropractic teaching clinic. Important barriers and facilitators were identified and will be used to inform future work regarding patient safety education and research.

Chiropractic Care of Adults With Postpartum-Related Low Back, Pelvic Girdle, or Combination Pain: A Systematic Review.

OBJECTIVE: The purpose of this study was to conduct a systematic review (SR) of the literature to assess the effectiveness of specific chiropractic care options commonly used for postpartum low back pain (LBP), pelvic girdle pain (PGP), or combination (LBP and PGP) pain. METHODS: A search strategy was developed. Interventions were those manual or other nonpharmacologic therapies commonly used by chiropractors (not requiring additional certifications). The outcomes were self-reported changes in pain or disability self-reported outcomes. We used the Scottish Intercollegiate Guideline Network checklists. Strength of the evidence (excluding cohort studies) was determined using an adapted version of the US Preventive Services Task Force criteria as described in the UK report. RESULTS: Of the 1611 published articles, 16 were included. These were 5 SRs, 10 randomized controlled trials (RCTs), and 1 cohort study. Postpartum LBP (1 RCT): moderate, favorable strength for spinal manipulation therapy/mobilization. Postpartum PGP (4 RCTs): moderate, unclear strength for exercise; and inconclusive, unclear strength for patient education. Postpartum LBP or PGP (3 SRs and 4 RCTs): inconclusive, unclear strength for exercise, self-management, and physiotherapy; while osteopathic manipulative therapy was inconclusive, favorable. CONCLUSION: No treatment option was identified as having sufficient evidence to make a clear recommendation. This SR identified a scarcity of literature regarding chiropractic care and back pain for postpartum women, as well as inconsistency among the terms LBP, PGP, and combination pain.

Exploring supervised machine learning approaches to predicting Veterans Health Administration chiropractic service utilization.

BACKGROUND: Chronic spinal pain conditions affect millions of US adults and carry a high healthcare cost burden, both direct and indirect. Conservative interventions for spinal pain conditions, including chiropractic care, have been associated with lower healthcare costs and improvements in pain status in different clinical populations, including veterans. Little is currently known about predicting healthcare service utilization in the domain of conservative interventions for spinal pain conditions, including the frequency of use of chiropractic services. The purpose of this retrospective cohort study was to explore the use of supervised machine learning approaches to predicting one-year chiropractic service utilization by veterans receiving VA chiropractic care. METHODS: We included 19,946 veterans who entered the Musculoskeletal Diagnosis Cohort between October 1, 2003 and September 30, 2013 and utilized VA chiropractic services within one year of cohort entry. The primary outcome was one-year chiropractic service utilization following index chiropractic visit, split into quartiles represented by the following classes: 1 visit, 2 to 3 visits, 4 to 6 visits, and 7 or greater visits. We compared the performance of four multiclass classification algorithms (gradient boosted classifier, stochastic gradient descent classifier, support vector classifier, and artificial neural network) in predicting visit quartile using 158 sociodemographic and clinical features. RESULTS: The selected algorithms demonstrated poor prediction capabilities. Subset accuracy was 42.1% for the gradient boosted classifier, 38.6% for the stochastic gradient descent classifier, 41.4% for the support vector classifier, and 40.3% for the artificial neural network. The micro-averaged area under the precision-recall curve for each one-versus-rest classifier was 0.43 for the gradient boosted classifier, 0.38 for the stochastic gradient descent classifier, 0.43 for the support vector classifier, and 0.42 for the artificial neural network. Performance of each model yielded only a small positive shift in prediction probability (approximately 15%) compared to naïve classification. CONCLUSIONS: Using supervised machine learning to predict chiropractic service utilization remains challenging, with only a small shift in predictive probability over naïve classification and limited clinical utility. Future work should examine mechanisms to improve model performance.

Understanding patient profiles and characteristics of current chiropractic practice: a cross-sectional Ontario Chiropractic Observation and Analysis STudy (O-COAST).

OBJECTIVES: There is no current detailed profile of people seeking chiropractic care in Canada. We describe the profiles of chiropractors' practice and the reasons, nature of the care provided to their patients and extent of interprofessional collaborations in Ontario, Canada. DESIGN: Cross-sectional observational study. SETTING: Primary care setting in Ontario, Canada. PARTICIPANTS: We randomly recruited chiropractors from a list of registered chiropractors (n=3978) in active practice in 2015. Of the 135 randomly selected chiropractors, 120 were eligible, 43 participated and 42 completed the study. OUTCOME MEASURES: Each chiropractor recorded information for up to 100 consecutive patient encounters, documenting patient health profiles, reasons for encounter, diagnoses and care provided. Descriptive statistics summarised chiropractor, patient and encounter characteristics, with analyses accounting for clustering and design effects. RESULTS: Chiropractors provided data on 3523 chiropractor-patient encounters. More than 65% of participating chiropractors were male, mean age 44 years and had practised on average 15 years. The typical patient was female (59% of encounters), between 45 and 64 years (43%) and retired (21%) or employed in business and administration (13%). Most (39.4%) referrals were from other patients, with 6.8% from physicians. Approximately 68% of patients paid out of pocket or claimed extended health insurance for care. Most common diagnoses were back (49%, 95% CI 44 to 56) and neck (15%, 95% CI 13 to 18) problems, with few encounters related to maintenance/preventive care (0.86%, 95% CI 0.2 to 3.9) and non-musculoskeletal problems (1.3%, 95% CI 0.7 to 2.3). The most common treatments included spinal manipulation (72%), soft tissue therapy (70%) and mobilisation (35%). CONCLUSIONS: This is the most comprehensive profile to date of chiropractic practice in Canada. People who present to Ontario chiropractors are mostly adults with a musculoskeletal condition. Our results can be used by stakeholders to make informed decisions about workforce development, education and healthcare policy related to chiropractic care.

Access to chiropractic care and the cost of spine conditions among older adults.

OBJECTIVES: Chiropractic care is a service that operates outside of the conventional medical system and is reimbursed by Medicare. Our objective was to examine the extent to which accessibility of chiropractic care affects spending on medical spine care among Medicare beneficiaries. STUDY DESIGN: Retrospective cohort study that used beneficiary relocation as a quasi-experiment. METHODS: We used a combination of national data on provider location and Medicare claims to perform a quasi-experimental study to examine the effect of chiropractic care accessibility on healthcare spending. We identified 84,679 older adults enrolled in Medicare with a spine condition who relocated once between 2010 and 2014. For each year, we measured accessibility using the variable-distance enhanced 2-step floating catchment area method. Using data for the years before and after relocation, we estimated the effect of moving to an area of lower or higher chiropractic accessibility on spine-related spending adjusted for access to medical physicians. RESULTS: There are approximately 45,000 active chiropractors in the United States, and local accessibility varies considerably. A negative dose-response relationship was observed for spine-related spending on medical evaluation and management as well as diagnostic imaging and testing (mean differences, $20 and $40, respectively, among those exposed to increasingly higher chiropractic accessibility; P <.05 for both). Associations with other types of spine-related spending were not significant. CONCLUSIONS: Among older adults, access to chiropractic care may reduce medical spending on services for spine conditions.

Differences in Function and Comorbidities Between Older Adult Users and Nonusers of Chiropractic and Osteopathic Manipulation: A Cross-sectional Analysis of the 2012 National Health Interview Survey.

OBJECTIVE: The purpose of this cross-sectional study was to compare functional limitations and comorbidity prevalence between older adult users and nonusers of chiropractic and osteopathic (DC/DO) manipulation to inform provider training. METHODS: We conducted a secondary analysis of the 2012 National Health Interview Survey data. Adults age 65 or older who responded to the survey were included. Descriptive statistics are reported for adults who used DC/DO manipulation (vs nonusers) regarding function, comorbidities, musculoskeletal complaints, and medical services. Weighted percentages were derived using SAS and compared with χ2 tests. RESULTS: The DC/DO users were more often female, overweight or obese, and of white race than nonusers. More DC/DO users reported arthritis (55.3% vs 47.0%, <0.01) or asthma (15.0% vs 10.0%, P < .01) than nonusers; hypertension (61.9% vs 55.5%, P = .02) and diabetes (20.3% vs 15.7%, P = .02) were more prevalent in nonusers; and other comorbidities were comparable. The DC/DO users reported more joint pain/stiffness (55.7% vs 44.8%), chronic pain (19.8% vs 14.2%), low back pain (27.8% vs 18.4%), low back with leg pain (18.8% vs 10.6%), and neck pain (24.2% vs 13.1%) than nonusers (all P < .01). Functional limitations affected two-thirds overall, but DC/DO users reported more difficulties stooping and bending; other limitations were comparable. One in 9 reported activities of daily living or instrumental activities of daily living limitations; nonusers were more affected. Surgery was more common among DC/DO users (26.1% vs 19.3%, <0.01); emergency room visits were comparable. CONCLUSION: Differences existed between older adult manipulation users and nonusers, especially surgical utilization, musculoskeletal complaints, and comorbidities; functional differences were modest. Our findings highlight areas for provider training and awareness regarding comorbidity burden and management needs in older patients who may simultaneously use manipulation and medical care for musculoskeletal complaints.

Health insurance design and conservative therapy for low back pain.

OBJECTIVES: To determine the association of health insurance benefit design features with choice of early conservative therapy for patients with new-onset low back pain (LBP). STUDY DESIGN: Observational study of 117,448 commercially insured adults 18 years or older presenting with an outpatient diagnosis of new-onset LBP between 2008 and 2013 as recorded in the OptumLabs Data Warehouse. METHODS: We identified patients who chose a primary care physician (PCP), physical therapist, or chiropractor as their entry-point provider. The main analyses were logistic regression models that estimated the likelihood of choosing a physical therapist versus a PCP and choosing a chiropractor versus a PCP. Key independent variables were health plan type, co-payment, deductible, and participation in a health reimbursement account (HRA) or health savings account (HSA). Models controlled for patient demographic and clinical characteristics. RESULTS: Selection of entry-point provider was moderately responsive to the incentives that patients faced. Those covered under plan types with greater restrictions on provider choice were less likely to choose conservative therapy compared with those covered under the least restrictive plan type. Results also indicated a general pattern of higher likelihood of treatment with physical therapy at lower levels of patient cost sharing. We did not observe consistent associations between participation in HRAs or HSAs and choice of conservative therapy. CONCLUSIONS: Modification of health insurance benefit designs offers an opportunity for creating greater value in treatment of new-onset LBP by encouraging patients to choose noninvasive conservative management that will result in long-term economic and social benefits.

Maternal Report of Outcomes of Chiropractic Care for Infants.

OBJECTIVE: The purpose of this study was to investigate the report by mothers of their infants' condition before and after a trial of care provided by registered chiropractic clinicians in addition to ratings of satisfaction, cost of care, and reports of any adverse events or side effects. A second purpose was to report the demographic profile of infants who presented for care to 16 chiropractic clinics in the United Kingdom. METHODS: This observational study prospectively collected reports by mothers of their infants' demographic profiles and outcomes across several domains of infant behavior and their own mental state using the United Kingdom Infant Questionnaire. Participating registered chiropractors were recruited through the Royal College of Chiropractors annual meeting in January 2016, and 15 clinics and the Anglo-European College of Chiropractic University College teaching clinic volunteered to participate. RESULTS: In all, 2001 mothers completed intake questionnaires and 1092 completed follow-up forms. Statistically significant (P < .05) improvements were reported across all aspects of infant behavior studied, including feeding problems, sleep issues, excessive crying, problems with supine sleep position, infant pain, restricted cervical range of motion, and time performing prone positioning. Maternal ratings of depression, anxiety, and satisfaction with motherhood also demonstrated statistically significant improvement (P < .05). In total, 82% (n = 797) reported definite improvement of their infants on a global impression of change scale. As well, 95% (n = 475) reported feeling that the care was cost-effective, and 90.9% (n = 712) rated their satisfaction 8 or higher on an 11-point scale. Minor self-limiting side effects were reported (5.8%, n = 42/727) but no adverse events. CONCLUSION: In this study, mothers reported that chiropractic care for their infants was effective, safe, and cost-effective. Although the observational design makes it impossible to determine efficacy, the study's findings indicate that, on average, the changes observed by mothers were positive and may be clinically relevant.

Contrasting real time quantitative measures (weekly SMS) to patients' retrospective appraisal of their one-year's course of low back pain; a probing mixed-methods study.

Background: Due to the recurrent nature of low back pain (LBP), the traditional concepts of cure and recovery are challenged, and investigating the course rather than status at fixed time-points may help us understand prognosis as well as treatment effect. However, methods of frequent measuring still need development and validation. Therefore, this study aims to evaluate the agreement between continuous, quantitative self-assessment (weekly SMS) of the course of LBP over a one-year period and qualitatively derived retrospective patient self-appraisal of the same time-period. Methods: Participants were 32 subjects with LBP from primary care. The quantitative measures consisted of weekly SMS questions for one-year about pain intensity, days with LBP, and activity limitations for that week. For each subject, the weekly responses were graphed and categorized into categories based on intensity, variation and overall change patterns. Qualitative measures were based on semi-structured telephone interviews one-year after a consultation for LBP, where two coders independently categorized the self-appraisal of LBP course into the same predefined categories as the SMS-based trajectories. Furthermore, patients' perceived overall recovery was related to variation patterns from SMS track. Results: There was perfect agreement for 48% in the pain intensity domain, 53% in the variation domain and 63% in the change pattern domain. Most of the discordant cases were classified in neighboring categories with the majority relating to fluctuating patterns. The self-perceived overall recovery status seemed to be reflected quite well by the quantitative measures of pain intensity and days with pain in this study. Conclusion: This study shows that a real time quantitative measure (weekly SMS) and the patient's retrospective appraisal do not fundamentally differ in their reflection of the one-year course of LBP.As a first investigation into this area, these results are promising, as longitudinal quantitatively derived trajectories of LBP seem to reflect the lived experience of the patient to a large degree. Furthermore, the patient's ability to retrospectively recall their one-year course of LBP appears to be quite good. Future studies should focus on refining the categories of trajectories.

An observational study on trajectories and outcomes of chronic low back pain patients referred from a spine surgery division for chiropractic treatment.

Background: A close collaboration between surgeons and non-surgical spine experts is crucial for optimal care of low back pain (LBP) patients. The affiliation of a chiropractic teaching clinic to a university hospital with a large spine division in Zurich, Switzerland, enables such collaboration. The aim of this study was to describe the trajectories and outcomes of patients with chronic LBP referred from the spine surgery division to the chiropractic teaching clinic. Methods: The patients filled in an 11-point numeric rating scale (NRS) for pain intensity and the Bournemouth Questionnaire (BQ) (bio-psycho-social measure) at baseline and after 1 week, 1, 3, 6 and 12 months. Additionally, the Patient's Global Impression of Change (PGIC) scale was recorded at all time points apart from baseline. The courses of NRS and BQ were analyzed using linear mixed model analysis and repeated measures ANOVA. The proportion of patients reporting clinically relevant overall improvement (PGIC) was calculated and the underlying factors were determined using logistic regression analyses. Results: Between June 2014 and October 2016, 67 participants (31 male, mean age = 46.8 ± 17.6 years) were recruited, of whom 46 had suffered from LBP for > 1 year, the rest for > 3 months, but < 1 year. At baseline, mean NRS was 5.43 (SD 2.37) and mean BQ was 39.80 (SD 15.16) points. NRS significantly decreased [F(5, 106.77) = 3.15, p = 0.011] to 4.05 (SD 2.88) after 12 months. A significant reduction was not observed before 6 months after treatment start (p = 0.04). BQ significantly diminished [F(5, 106.47) = 6.55, p < 0.001] to 29.00 (SD 17.96) after 12 months and showed a significant reduction within the first month (p < 0.01). The proportion of patients reporting overall improvement significantly increased from 23% after 1 week to 47% after 1 month (p = 0.004), when it stabilized [56% after 3 and 6 months, 44% after 12 months]. Reduction in bio-psycho-social impairment (BQ) was of higher importance for overall improvement than pain reduction. Conclusions: Chiropractic treatment is a valuable conservative treatment modality associated with clinically relevant improvement in approximately half of patients with chronic LBP. These findings provide an example of the importance of interdisciplinary collaboration in the treatment of chronic back pain patients.

Physical Therapy Service delivered in the Polyclinic During the Rio 2016 Paralympic Games.

OBJECTIVE: To characterize the Physical Therapy Services delivered at the Polyclinic during the Rio 2016 Paralympic Games. DESIGN: Retrospective Cohort Study. SETTING: Physical Therapy Services (PTS) of the Polyclinic. PARTICIPANTS: Athletes attended for Physical Therapy treatment at the Polyclinic during Rio 2016 Paralympic Games. MAIN OUTCOME MEASURES: The number of athletes treated, their nationalities, their sports modality, the most frequently treated regions and the interventions applied. RESULTS: A total of 4504 interventions were delivered and 399 athletes were treated in the PTS. Athletes representing athletics and sitting volleyball were the most frequently attended for treatment. The main diagnoses were muscle tension and tendinopathy. Analgesia was the main purpose of treatment and myofascial release and electrotherapy was the most frequent interventions. Recovery service had a total of 1579 encounters and male athletes used cryo-immersion 3 times more when compared to female. CONCLUSION: Athletes representing athletics and sitting volleyball were the most frequently attended for treatment and the thoracic/lumbar spine and pelvis/hip were the most commonly affected regions. Muscle strain and tendinopathy were the most frequent diagnoses and myofascial release and electrotherapy were the most frequent therapies used to achieve analgesia.

Exploring Chiropractic Services in the Canadian Forces Health Services - Perceptions of Facilitators and Barriers Among Key Informants.

INTRODUCTION: Musculoskeletal (MSK) conditions have a significant impact on the health and operational readiness of military members. The Canadian Forces Health Services (CFHS) provides a spectrum of health services in managing Canadian Armed Forces (CAF) personnel health care needs with on-base and off-base services provided by civilian and uniformed health care professionals, including chiropractors. Although chiropractic services are available in US DoD and VA systems, little is known about the facilitators and barriers to integrating on-base chiropractic services within the CFHS. This study explored key informants' perceptions of facilitators and barriers to the integration of on-base chiropractic services within the CFHS. METHODS: We conducted a qualitative study to describe and understand how an integrated chiropractic service could be designed, implemented, and evaluated within the current interdisciplinary CFHS. Telephone interviews were conducted, using a semi-structured interview guide, to explore key informants' perceptions and experiences of chiropractic care within the CFHS. In total, we invited 27 individuals across Canada to participate; 15 were identified through purposeful sampling, 12 through a snowball sampling technique, and 2 declined. The 25 participants included military personnel (52%), public servants and contractors employed by the Department of Defense (24%), as well as civilian health care providers (24%). All participants were health care providers [physicians (MD) (7), physiotherapists (PT) (13), chiropractors (DC) (5)]. Interviews were audio-recorded and transcribed verbatim. Transcripts were prepared and analyzed using an interpretivist approach that explored key informants' perceptions and experiences. RESULTS: Qualitative analysis revealed numerous facilitators and barriers to chiropractic services in the CFHS. These were categorized under three broad themes: base-to-base variations, variable gatekeeper roles, and referral processes. Barriers to integrating chiropractic services included: lack of clarity about a chiropractor's clinical knowledge and skills; CFHS team members' negative prior experiences with chiropractors (e.g., inappropriate patient-focused communication, clinical management that was not evidence-based, ignorance of military culture); suboptimal bi-directional communication between CAF personnel and DCs across bases; and wide-ranging perspectives pertaining to duplication of services offered by PTs and DCs in managing MSK conditions. Facilitators associated with the integration of chiropractic services within a collaborative and interdisciplinary CAF environment included: patient benefits associated with multiple approaches utilized by different providers; adoption of up-to-date, high-quality evidence and guidelines to standardize care and curtail "dependency" between patient and providers; and co-location of providers to strengthen existing interprofessional communication and relationships. Key informants called for patient care that is collaborative, integrated and patient-centered, rather than "patient-driven" care; civilian providers understanding and respecting military culture rather than assuming transferability of patient management processes from the public civilian sector; standardization of communication protocols and measures to evaluate outcomes of care; and the need to move slowly and respectfully within the current CAF health care system if planning the on-base implementation of chiropractic services. CONCLUSION: This study illuminated many opportunities and barriers, in complex and diverse domains, related to introducing collaborative chiropractic services in the CFHS. The findings are relevant to increasing understanding and strengthening interprofessional collaborative care within the unique CAF health care delivery system.

Use of Yoga, Meditation, and Chiropractors Among U.S. Adults Aged 18 and Over.

Complementary health is the use of holistic or unconventional medicine with mainstream Western medicine for health and wellness (1,2). Past research has identified yoga, meditation, and seeing a chiropractor as some of the most commonly used approaches (3). This report examines changes over time in the percentage of adults who used yoga, meditation, and chiropractors in the past 12 months, as well as variation by sex, age, and race and Hispanic origin.

Use of Yoga, Meditation, and Chiropractors Among U.S. Children Aged 4-17 Years.

Yoga, meditation, and use of chiropractors are types of complementary health approaches developed outside of mainstream Western medicine (1-2). Although complementary health approaches as a whole are not widely used among children, previous work has established a rise in the use of selected approaches over time (3). This report presents the most recent national estimates of use of the three most prevalent approaches during the past 12 months, among children aged 4-17 years in the United States. Comparable estimates from 2012 are also included to examine changes over time.

Characteristics of Chiropractic Patients Being Treated for Chronic Low Back and Neck Pain.

OBJECTIVES: Chronic low back pain (CLBP) and chronic neck pain (CNP) are the most common types of chronic pain, and chiropractic spinal manipulation is a common nonpharmacologic treatment. This study presents the characteristics of a large United States sample of chiropractic patients with CLBP and CNP. METHODS: Data were collected from chiropractic patients using multistage systematic stratified sampling with 4 sampling levels: regions and states, sites (ie, metropolitan areas), providers and clinics, and patients. The sites and regions were San Diego, California; Tampa, Florida; Minneapolis, Minnesota; Seneca Falls and Upstate New York; Portland, Oregon; and Dallas, Texas. Data were collected from patients through an iPad-based prescreening questionnaire in the clinic and emailed links to full screening and baseline online questionnaires. The goal was 20 providers or clinics and 7 patients with CLBP and 7 with CNP from each clinic. RESULTS: We had 6342 patients at 125 clinics complete the prescreening questionnaire, 3333 patients start the full screening questionnaire, and 2024 eligible patients completed the baseline questionnaire: 518 with CLBP only, 347 with CNP only, and 1159 with both. In general, most of this sample were highly-educated, non-Hispanic, white females with at least partial insurance coverage for chiropractic care who have been in pain and using chiropractic care for years. Over 90% reported high satisfaction with their care, few used narcotics, and avoiding surgery was the most important reason they chose chiropractic care. CONCLUSIONS: Given the prevalence of CLBP and CNP, the need to find effective nonpharmacologic alternatives for chronic pain, and the satisfaction these patients found with their care, further study of these patients is worthwhile.
