  • Moderators of the Effects of Telehealth Mindfulness-based Interventions for Chronic Pain

    by Collin M. Calvert, Emily M. Hagel Campbell, Lee J.S. Cross, Ann Bangerter, Gert Bronfort, Roni Evans, Laura A. Meis, Alexander Haley, Brent Leininger, Marianne Matthias, et al.

    Objectives: Little is known about who benefits most from Mindfulness-Based Interventions (MBIs), and whether certain groups differentially benefit from different types of MBI formats (group-based versus non-group based). The present study uses data from a three-arm randomized controlled trial (ClinicalTials.gov ID: NCT04526158) of two MBIs (self-paced and group) to test moderating effects by gender and diagnoses of three mental health conditions (depression, anxiety, and post-traumatic stress disorder). Methods: The sample consisted of 811 veterans with moderate to severe chronic pain, recruited from three Veterans Affairs sites from 2020 to 2022. Survey data were collected at baseline and three follow-up timepoints (10 weeks, 6 months, and 12 months). A responder analysis approach was used to measure clinically important changes. Outcomes were improvement from baseline in pain interference, pain intensity, anxiety, depression, PTSD, fatigue, sleep disturbance, physical function, and social functioning. Results: The group MBI and self-paced MBI arms had higher rates of improvement in all outcomes compared to usual care. In the group MBI, women had greater improvement in pain severity and depression than men, and those with anxiety diagnoses had less improvement in PTSD than those without anxiety. Discussion: Overall, both MBIs benefitted participants across subgroups, with limited evidence for differential effects by gender or mental health diagnoses. Further research is needed to more systematically determine whether MBIs can be optimized for key subgroups.

  • Extracting Complementary and Integrative Health Approaches in Electronic Health Records

    by Huixue Zhou, Greg Silverman, Zhongran Niu, Jenzi Silverman, Roni Evans, Robin Austin, Rui Zhang

    Complementary and Integrative Health (CIH) has gained increasing popularity in the past decades. While the evidence bases to support them are growing, there is still a gap in understanding their effects and potential adverse events using real-world data. The overall goal of this study is to represent information pertinent to both psychological and physical CIH approaches (specifically, using examples of music therapy, chiropractic, and aquatic exercise in this study) in an electronic health record (EHR) system. We also aim to evaluate the ability of existing natural language processing (NLP) systems to identify CIH approaches. A total of 300 notes were randomly selected and manually annotated. Annotations were made for status, symptom, and frequency of each approach. This set of annotations was used as a gold standard to evaluate the performance of NLP systems used in this study (specifically BioMedICUS, MetaMap, and cTAKES) for extracting CIH concepts. Venn diagram was used to investigate the consistency of medical records searching by Current Procedural Terminology (CPT) codes and CIH approaches keywords in SQL. Since CPT codes usually do not have specific mentions of CIH approaches, the Venn diagram had less overlap with those found in clinical notes for all three CIH therapies. The three NLP systems achieved 0.41 in average lenient match F1-score in all three CIH approaches, respectively. BioMedICUS achieved the best performance in aquatic exercise with an F1-score of 0.66. This study contributes to the overall representation of CIH in clinical note and lays a foundation for using EHR for clinical research for CIH approaches.

    Multidisciplinary integrative care versus chiropractic care for low back pain: a randomized clinical trial

    by Gert Bronfort, Michele Maiers, Craig Schulz, Brent Leininger, Kristine Westrom, Greg Angstman, Roni Evans

    Background: Low back pain (LBP) is influenced by interrelated biological, psychological, and social factors, however current back pain management is largely dominated by one-size fits all unimodal treatments. Team based models with multiple provider types from complementary professional disciplines is one way of integrating therapies to address patients’ needs more comprehensively.Methods: This parallel group randomized clinical trial conducted from May 2007 to August 2010 aimed to evaluate the relative clinical effectiveness of 12 weeks of monodisciplinary chiropractic care (CC), versus multidisciplinary integrative care (IC), for adults with sub-acute and chronic LBP. The primary outcome was pain intensity and secondary outcomes were disability, improvement, medication use, quality of life, satisfaction, frequency of symptoms, missed work or reduced activities days, fear avoidance beliefs, self-efficacy, pain coping strategies and kinesiophobia measured at baseline and 4, 12, 26 and 52 weeks. Linear mixed models were used to analyze outcomes.Results: 201 participants were enrolled. The largest reductions in pain intensity occurred at the end of treatment and were 43% for CC and 47% for IC. The primary analysis found IC to be significantly superior to CC over the 1-year period (P = 0.02). The long-term profile for pain intensity which included data from weeks 4 through 52, showed a significant advantage of 0.5 for IC over CC (95% CI 0.1 to 0.9;P = 0.02; 0 to 10 scale). The short-term profile (weeks 4 to 12) favored IC by 0.4, but was not statistically significant (95% CI − 0.02 to 0.9;P = 0.06). There was also a significant advantage over the long term for IC in some secondary measures (disability, improvement, satisfaction and low back symptom frequency), but not for others (medication use, quality of life, leg symptom frequency, fear avoidance beliefs, self-efficacy, active pain coping, and kinesiophobia). Importantly, no serious adverse events resulted from either of the interventions.Conclusions: Participants in the IC group tended to have better outcomes than the CC group, however the magnitude of the group differences was relatively small. Given the resources required to successfully implement multidisciplinary integrative care teams, they may not be worthwhile, compared to monodisciplinary approaches like chiropractic care, for treating LBP.Trial registrationNCT00567333.

    Design of a mindfulness-based intervention to support teachers’ emotional regulation behaviors

    by Douglas P. Kennedy, Alex Haley, Roni Evans

    Addressing teachers’ ability to better navigate stress and emotional responses has the potential to improve classroom behaviors, student learning as well as teachers’ wellbeing. While there is growing interest in mindfulness-based interventions (MBIs), there is need for greater attention to design aligned with relevant theories and transparent reporting to improve the rigor and translation of research. While utilized widely in health and behavior fields, behavior change theory has not been applied extensively in education or MBI research. This descriptive methodological paper articulates the intervention mapping and design process of an MBI to improve teachers’ stress and emotional regulation. To improve reporting, we use a post hoc application of a well-established behavioral model. Application of the Behavior Change Wheel (BCW) as part of an intervention mapping approach for an MBI to align teacher’s needs with intervention elements most likely to achieve desired behavioral outcomes. The paper illustrates an approach which includes defining the problem in behavioral terms, identification of target behaviors and behavioral change techniques, and selection of strategies and modes of intervention delivery. A systematic intervention mapping approach applying the BCW can yield a holistic MBI for the desired behavior change, enhanced emotion and stress regulation in teachers. This example of applying the BCW to the design of an MBI demonstrates how intervention designers and researchers can make decisions about which techniques and delivery components to include in their interventions, and how to systematically describe them. Such approaches have the potential to improve the reporting and methodological rigor of future MBI research and the successful application of interventions in practice.

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

    by Eric J. Roseen, Aisha B. Kasali, Kelsey Corcoran, Kelsey Masselli, Lance Laird, Robert B Saper, Daniel P. Alford, Ezra Cohen, Anthony Lisi, Steven J. Atlas, et al.

    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 nonpharmacologic treatment aligned with international clinical practice guidelines. Although DCs practice in at least 90 countries, chiropractic care is often not available within integrated health care delivery systems. A lack of DCs in private practice, particularly in low-income communities, may also limit access to chiropractic care. Improved collaboration between medical providers and community-based DCs, or embedding DCs in medical settings such as hospitals or community health centers, 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 health care 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 (e.g., 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. 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 health care delivery systems. Strengths and limitations of this study: This scoping review will be among the first to comprehensively map literature of doctors of chiropractic (DCs) working with or within military, veteran or civil integrated health care delivery systems. The literature search strategy is comprehensive and potentially generalizable to a global DC workforce, and relevant to other nonpharmacologic therapy providers who typically work in the community, e.g., acupuncturists, psychologists. A multidisciplinary team with diverse clinical and research expertise will inform our scoping review across all stages of the work. We have organized our search strategy and extraction form/guide around standardized terminology from the field of implementation science. It may be challenging to identify relevant studies, or extract all useful information, if original research does not use this terminology. Non-English articles describing the implementation of chiropractic care in a medical setting may be missed.

    Promoting the use of self-management in patients with spine pain managed by chiropractors and chiropractic interns: barriers and design of a theory-based knowledge translation intervention

    by Owis Eilayyan, Aliki Thomas, Marie-Christine Hallé, Sara Ahmed, Anthony C. Tibbles, Craig Jacobs, Silvano Mior, Connie Davis, Roni Evans, Michael J. Schneider, et al.

    Background: The literature supports the effectiveness of self-management support (SMS) to improve health outcomes of patients with chronic spine pain. However, patient engagement in SMS programs is suboptimal. The objectives of this study were to: 1) assess participation in self-care (i.e. activation) among patients with spine pain, 2) identify patients’ barriers and enablers to using SMS, and 3) map behaviour change techniques (BCTs) to key barriers to inform the design of a knowledge translation (KT) intervention aimed to increase the use of SMS.Methods: In summer 2016, we invited 250 patients with spine pain seeking care at the Canadian Memorial Chiropractic College in Ontario, Canada to complete the Patient Activation Measure (PAM) survey to assess the level of participation in self-care. We subsequently conducted individual interviews, in summer 2017, based on the Theoretical Domains Framework (TDF) in a subset of patients to identify potential challenges to using SMS. The interview guide included 20 open-ended questions and accompanying probes. Findings were deductively analysed guided by the TDF. A panel of 7 experts mapped key barriers to BCTs, designed a KT intervention, and selected the modes of delivery.Results: Two hundred and twenty-three patients completed the PAM. Approximately 24% of respondents were not actively involved in their care. Interview findings from 13 spine pain patients suggested that the potential barriers to using SMS corresponded to four TDF domains:Environmental Context and Resources; Emotion; Memory, Attention & Decision-Making; and Behavioural Regulation. The proposed theory-based KT intervention includes paper-based educational materials, webinars and videos, summarising and demonstrating the therapeutic recommendations including exercises and other lifestyle changes. In addition, the KT intervention includes Brief Action Planning, a SMS strategy based on motivational interviewing, along with a SMART plan and reminders.Conclusions: Almost one quarter of study participants were not actively engaged in their spine care. Key barriers likely to influence uptake of SMS among patients were identified and used to inform the design of a theory-based KT intervention to increase their participation level. The proposed multi-component KT intervention may be an effective strategy to optimize the quality of spine pain care and improve patients’ health-outcomes.

    Spinal manipulative therapy and exercise for older adults with chronic low back pain: a randomized clinical trial

    by Craig Schulz, Roni Evans, Michele Maiers, Karen Schulz, Brent Leininger, Gert Bronfort

    Low back pain (LBP) is a common disabling condition in older adults which often limits physical function and diminishes quality of life. Two clinical trials in older adults have shown spinal manipulative therapy (SMT) results in similar or small improvements relative to medical care; however, the effectiveness of adding SMT or rehabilitative exercise to home exercise is unclear. We conducted a randomized clinical trial assessing the comparative effectiveness of adding SMT or supervised rehabilitative exercise to home exercise in adults 65 or older with sub-acute or chronic LBP. Treatments were provided over 12-weeks and self-report outcomes were collected at 4, 12, 26, and 52 weeks. The primary outcome was pain severity. Secondary outcomes included back disability, health status, medication use, satisfaction with care, and global improvement. Linear mixed models were used to analyze outcomes. The primary analysis included longitudinal outcomes in the short (week 4–12) and long-term (week 4–52). An omnibus test assessing differences across all groups over the year was used to control for multiplicity. Secondary analyses included outcomes at each time point and responder analyses. This study was funded by the US Department of Health and Human Services, Health Resources and Services Administration. 241 participants were randomized and 230 (95%) provided complete primary outcome data. The primary analysis showed group differences in pain over the one-year were small and not statistically significant. Pain severity was reduced by 30 to 40% after treatment in all 3 groups with the largest difference (eight percentage points) favoring SMT and home exercise over home exercise alone. Group differences at other time points ranged from 0 to 6 percentage points with no consistent pattern favoring one treatment. One-year post-treatment pain reductions diminished in all three groups. Secondary self-report outcomes followed a similar pattern with no important group differences, except satisfaction with care, where the two combination groups were consistently superior to home exercise alone. Adding spinal manipulation or supervised rehabilitative exercise to home exercise alone does not appear to improve pain or disability in the short- or long-term for older adults with chronic low back pain, but did enhance satisfaction with care.

    Cost-effectiveness of spinal manipulation, exercise, and self-management for spinal pain using an individual participant data meta-analysis approach: a study protocol

    by Brent Leininger, Gert Bronfort, Roni Evans, James Hodges, Karen Kuntz, John A. Nyman

    Spinal pain is a common and disabling condition with considerable socioeconomic burden. Spine pain management in the United States has gathered increased scrutiny amidst concerns of overutilization of costly and potentially harmful interventions and diagnostic tests. Conservative interventions such as spinal manipulation, exercise and self-management may provide value for the care of spinal pain, but little is known regarding the cost-effectiveness of these interventions in the U.S. Our primary objective for this project is to estimate the incremental cost-effectiveness of spinal manipulation, exercise therapy, and self-management for spinal pain using an individual patient data meta-analysis approach. We will estimate the incremental cost-effectiveness of spinal manipulation, exercise therapy, and self-management using cost and clinical outcome data collected in eight randomized clinical trials performed in the U.S. Cost-effectiveness will be assessed from both societal and healthcare perspectives using QALYs, pain intensity, and disability as effectiveness measures. The eight randomized clinical trials used similar methods and included different combinations of spinal manipulation, exercise therapy, or self-management for spinal pain. They also collected similar clinical outcome, healthcare utilization, and work productivity data. A two-stage approach to individual patient data meta-analysis will be conducted. This project capitalizes on a unique opportunity to combine clinical and economic data collected in a several clinical trials that used similar methods. The findings will provide important information on the value of spinal manipulation, exercise therapy, and self-management for spinal pain management in the U.S.

    Promoting the use of self-management in novice chiropractors treating individuals with spine pain: the design of a theory-based knowledge translation intervention

    by Owis Eilayyan, Aliki Thomas, Marie-Christine Hallé, Sara Ahmed, Anthony C. Tibbles, Craig Jacobs, Silvano Mior, Connie Davis, Roni Evans, Michael J. Schneider, et al.

    Clinical practice guidelines generally recommend clinicians use self-management support (SMS) when managing patients with spine pain. However, even within the educational setting, the implementation of SMS remains suboptimal. The objectives of this study were to 1) estimate the organizational readiness for change toward using SMS at the Canadian Memorial Chiropractic College (CMCC), Toronto, Ontario from the perspective of directors and deans, 2) estimate the attitudes and self-reported behaviours towards using evidence-based practice (EBP), and beliefs about pain management among supervisory clinicians and chiropractic interns, 3) identify potential barriers and enablers to using SMS, and 4) design a theory-based tailored Knowledge Translation (KT) intervention to increase the use of SMS. Mixed method design. We administered three self-administered questionnaires to assess clinicians’ and interns’ attitudes and behaviours toward EBP, beliefs about pain management, and practice style. In addition, we conducted 3 focus groups with clinicians and interns based on the Theoretical Domain Framework (TDF) to explore their beliefs about using SMS for patients with spine pain. Data were analysed using deductive thematic analysis by 2 independent assessors. A panel of 7 experts mapped behaviour change techniques to key barriers identified informing the design of a KT intervention. Participants showed high level of EBP knowledge, positive attitude of EBP, and moderate frequency of EBP use. A number of barrier factors were identified from clinicians (N = 6) and interns (N = 16) corresponding to 7 TDF domains: Knowledge; Skills; Environmental context and resources; Emotion; Beliefs about Capabilities; Memory, attention & decision making; and Social Influence. To address these barriers, the expert panel proposed a multifaceted KT intervention composed of a webinar and online educational module on a SMS guided by the Brief Action Planning, clinical vignettes, training workshop, and opinion leader support. SMS strategies can help maximizing the health care services for patients with spine pain. This may in turn optimize patients’ health. The proposed theory-based KT intervention may facilitate the implementation of SMS among clinicians and interns.

    The effectiveness and feasibility of an online educational program for improving evidence-based practice literacy: an exploratory randomized study of US chiropractors

    by Michael Schneider, Roni Evans, Mitchell Haas, Matthew Leach, Louise Delagran, Cheryl Hawk, Cynthia Long, Gregory D. Cramer, Oakland Walters, Corrie Vihstadt, et al.

    Online education programs are becoming a popular means to disseminate knowledge about evidence-based practice (EBP) among healthcare practitioners. This mode of delivery also offers a viable and potentially sustainable solution for teaching consistent EBP content to learners over time and across multiple geographical locations. We conducted a study with 3 main aims: 1) develop an online distance-learning program about the principles of evidence-based practice (EBP) for chiropractic providers; 2) test the effectiveness of the online program on the attitudes, skills, and use of EBP in a sample of chiropractors; and 3) determine the feasibility of expanding the program for broader-scale implementation. This study was conducted from January 2013 to September 2014. This was an exploratory randomized trial in which 293 chiropractors were allocated to either an online EBP education intervention or a waitlist control. The online EBP program consisted of 3 courses and 4 booster lessons, and was developed using educational resources created in previous EBP educational programs at 4 chiropractic institutions. Participants were surveyed using a validated EBP instrument (EBASE) with 3 rescaled (0 to 100) subscores: Attitudes, Skills, and Use of EBP. Multiple regression was used to compare groups, adjusting for personal and practice characteristics. Satisfaction and compliance with the program was evaluated to assess feasibility. The Training Group showed modest improvement compared to the Waitlist Group in attitudes (Δ =6.2, p < .001) and skills (Δ =10.0, p < .001) subscores, but not the use subscore (Δ = −2.3, p = .470). The majority of participants agreed that the educational program was ‘relevant to their profession’ (84 %) and ‘was worthwhile’ (82 %). Overall, engagement in the online program was less than optimal, with 48 % of the Training Group, and 42 % of the Waitlist Group completing all 3 of the program courses. Online EBP training leads to modest improvements in chiropractors’ EBP attitudes and skill, but not their use of EBP. This online program can be delivered to a wide national audience, but requires modification to enable greater individualization and peer-to-peer interaction. Our results indicate that it is feasible to deliver an online EBP education on a broad scale, but that this mode of education alone is not sufficient for making large changes in chiropractors’ use of EBP.
