The effect of clinical guidelines on the utilisation of radiographs in chiropractic clinics in Denmark - an interrupted time series analysis.

BACKGROUND: In Denmark, chiropractors have a statutory right to use radiography and the government-funded national Health Insurance provides partial reimbursement. Danish National Clinical Guidelines recommends against routine use of imaging for uncomplicated spinal pain; however, it is not clear if clinical imaging guidelines recommendations have had an effect on the utilisation of spinal radiography. This study aimed to describe the utilisation rate of radiographs in Danish chiropractic clinics in the period from 2010 to 2020 and to assess the impact of clinical guidelines and policy changes on the utilisation of radiographs in Danish chiropractic clinics. METHODS: Anonymised data from January 1st, 2010, to December 31st, 2020, were extracted from the Danish Regions register on health contacts in primary care. Data consisted of the total number of patients consulting one of 254 chiropractic clinics and the total number of patients having or being referred for radiography. Data were used to investigate the radiography utilisation per month from 2010 to 2020. An 'interrupted time series' analysis was conducted to determine if two interventions, the dissemination of 1) Danish clinical imaging guidelines recommendations and policy changes related to referral for advanced imaging for chiropractors in 2013 and 2) four Danish clinical guidelines recommendations in 2016, were associated with an immediate change in the level and/or slope of radiography utilisation. RESULTS: In total, 336,128 unique patients consulted a chiropractor in 2010 of which 55,449 (15.4%) had radiography. In 2020, the number of patients consulting a chiropractor had increased to 366,732 of which 29,244 (8.0%) had radiography. The pre-intervention utilisation decreased by two radiographs per 10,000 patients per month. Little absolute change, but still statistically significant for Intervention 1, in the utilisation was found after the dissemination of the clinical guidelines and policy changes in 2013 or 2016. CONCLUSIONS: The proportion of Danish chiropractic patients undergoing radiography was halved in the period from 2010 to 2020. However, the dissemination of clinical imaging guidelines recommendations and policy changes related to referrals for advanced imaging showed little meaningful change in the monthly utilisation of radiographs in the same period.

Drivers, barriers, and response to care of Australian pregnant women seeking chiropractic care for low back and pelvic girdle pain: a qualitative case study.

BACKGROUND: Pregnancy-related low back and/or pelvic girdle pain is common, with a prevalence rate of up to 86% in pregnant women. Although 19.5% of Australian pregnant women visit a chiropractor for pelvic girdle pain, little is known about the experience of pregnant women who seek this care. The aim of this study was to describe and explore the experiences of Australian pregnant women who seek chiropractic care for their current pregnancy-related low back and/or pelvic girdle pain. METHODS: A qualitative case study approach with purposive sampling from 27 chiropractic practices was used. A grounded theory approach was informed by a constructivist and interpretivist stance, which provided understanding and meaning to the pregnant women's experiences. Online unstructured interviews were recorded, transcribed, and anonymised. A thematic analysis was subsequently conducted on the primary data. Codes and major themes were developed with the use of critical self- reflection (memos), survey finding triangulation and respondent validation. RESULTS: Sixteen potential respondents expressed interest in participating. After eligibility screening and data saturation, nine interviews were undertaken. Four key themes were identified: "Care drivers: what drives care seeking?", "Care barriers: what barriers are encountered?", "Chiropractic treatment: what does treatment consist of?" and "Response to care: what response was there to care?". CONCLUSION: Four key themes: care drivers, care barriers, chiropractic treatment, and response to care support an emergent substantive-level theory in women's care seeking experiences for pregnancy-related back pain and chiropractic care. This theory is that chiropractic care for pregnant women experiencing low back pain and pelvic girdle pain may improve pain and function, while reducing pregnancy-related biopsychosocial concerns. The findings may inform antenatal health providers and the chiropractic profession about pregnant women's experience seeking chiropractic care as well as directing future research.

Patient and provider characteristics associated with therapeutic intervention selection in a chiropractic clinical encounter: a cross-sectional analysis of the COAST and O-COAST study data.

BACKGROUND: Chiropractors use a variety of therapeutic interventions in clinical practice. How the selection of interventions differs across musculoskeletal regions or with different patient and provider characteristics is currently unclear. This study aimed to describe how frequently different interventions are used for patients presenting for chiropractic care, and patient and provider characteristics associated with intervention selection. METHODS: Data were obtained from the Chiropractic Observation and Analysis STudy (COAST) and Ontario (O-COAST) studies: practice-based, cross-sectional studies in Victoria, Australia (2010-2012) and Ontario, Canada (2014-2015). Chiropractors recorded data on patient diagnosis and intervention selection from up to 100 consecutive patient visits. The frequency of interventions selected overall and for each diagnostic category (e.g., different musculoskeletal regions) were descriptively analysed. Univariable multi-level logistic regression (provider and patient as grouping factors), stratified by diagnostic category, was used to assess the association between patient/provider variables and intervention selection. RESULTS: Ninety-four chiropractors, representative of chiropractors in Victoria and Ontario for age, sex, and years in practice, participated. Data were collected on 7,966 patient visits (6419 unique patients), including 10,731 individual diagnoses (mean age: 43.7 (SD: 20.7), 57.8% female). Differences in patient characteristics and intervention selection were observed between chiropractors practicing in Australia and Canada. Overall, manipulation was the most common intervention, selected in 63% (95%CI:62-63) of encounters. However, for musculoskeletal conditions presenting in the extremities only, soft tissue therapies were more commonly used (65%, 95%CI:62-68). Manipulation was less likely to be performed if the patient was female (OR:0.74, 95%CI:0.65-0.84), older (OR:0.79, 95%CI:0.77-0.82), presenting for an initial visit (OR:0.73, 95%CI:0.56-0.95) or new complaint (OR:0.82, 95%CI:0.71-0.95), had one or more comorbidities (OR:0.63, 95%CI:0.54-0.72), or was underweight (OR:0.47, 95%CI:0.35-0.63), or obese (OR:0.69, 95%CI:0.58-0.81). Chiropractors with more than five years clinical experience were less likely to provide advice/education (OR:0.37, 95%CI:0.16-0.87) and exercises (OR:0.17, 95%CI:0.06-0.44). CONCLUSION: In more than 10,000 diagnostic encounters, manipulation was the most common therapeutic intervention for spine-related problems, whereas soft tissue therapies were more common for extremity problems. Different patient and provider characteristics were associated with intervention selection. These data may be used to support further research on appropriate selection of interventions for common musculoskeletal complaints.

Physiotherapists should apply health coaching techniques and incorporate accountability to foster adherence to a walking program for low back pain: a qualitative study.

QUESTIONS: What motivates individuals to start a walking program for the prevention of low back pain? What strategies optimise short-term and long-term adherence to a walking program? What strategies can physiotherapists incorporate into clinical practice to facilitate commencement of and adherence to a walking program? DESIGN: Qualitative study. PARTICIPANTS: Twenty-two adults recently recovered from an episode of non-specific low back pain who participated in a 6-month, progressive and individualised walking program that was prescribed by a physiotherapist trained in health coaching. METHODS: Semi-structured focus groups conducted online following completion of the walking program. Interview questions explored: primary motivations for starting a walking program, identification of which elements were useful in optimising adherence to the program, and identification of the barriers to and facilitators of engagement with the program. Audio recordings were transcribed and thematic analysis was conducted. RESULTS: Three major themes were identified. Theme one identified that strong motivators to start a walking program were anticipated improvements in low back pain management and the added general health benefits of a more active lifestyle. Theme two identified that fear of high-impact exercises led to avoidance; however, walking was considered a safe exercise option. Theme three identified accountability, enjoyment of exercise and health benefits were critical to adherence. CONCLUSION: Participants recently recovered from low back pain reflected positively on a physiotherapist-prescribed walking program. Participants described what elements of the program were crucial to starting exercise and optimising adherence. These findings have informed a list of practical recommendations for physiotherapists to improve patient commencement and adherence to exercise.

Effectiveness and cost-effectiveness of a progressive, individualised walking and education program for prevention of low back pain recurrence in adults: statistical analysis plan for the WalkBack randomised controlled trial.

BACKGROUND: Exercise for the prevention of low back pain recurrences is recommended, but under-researched. The effectiveness and cost-effectiveness of a walking program for preventing low back pain recurrence remains unknown. This a priori statistical analysis plan describes the methods of analysis for the WalkBack trial. METHODS: WalkBack is a prospectively registered, pragmatic, randomised controlled trial. The aim is to investigate the effectiveness and cost-effectiveness of a 6-month progressive and individualised walking and education program (intervention) for the prevention of low back pain recurrences, compared to a no-treatment control group. The primary outcome is days to the first recurrence of an episode of activity-limiting low back pain. Key secondary outcomes include days to any recurrence of low back pain, days to a care-seeking recurrence of low back pain, disability level, health-related quality of life, costs associated with low back pain and adverse events. All participants will be followed for a minimum of 12 months. Analysis will follow the intention-to-treat principle. Cox regression is planned to assess the effects for the outcomes of time to activity-limiting, minimal and care-seeking recurrence. Hazard ratios and median survival times with 95% confidence intervals will be calculated. The effect of the intervention on continuous outcomes will be estimated with repeated-measure linear mixed models. An economic evaluation will be performed from the societal perspective for recurrence prevented (yes/no) and quality-adjusted life years. The proportion of adverse events between groups will be compared using Fisher's exact test. DISCUSSION: The WalkBack trial will provide evidence on the effectiveness and cost-effectiveness of a walking intervention to prevent low back pain recurrences. This statistical analysis plan provides transparency on the analysis of the trial.

Effectiveness of a New Service Delivery Model for Management of Knee Osteoarthritis in Primary Care: A Cluster Randomized Controlled Trial.

OBJECTIVE: To evaluate the effectiveness and health costs of a new primary care service delivery model (the Optimising Primary Care Management of Knee Osteoarthritis [PARTNER] model) to improve health outcomes for patients with knee osteoarthritis (OA) compared to usual care. METHODS: This study was a 2-arm, cluster, superiority, randomized controlled trial with randomization at the general practice level, undertaken in Victoria and New South Wales, Australia. We aimed to recruit 44 practices and 572 patients age ≥45 years with knee pain for >3 months. Professional development opportunities on best practice OA care were provided to intervention group general practitioners (GPs). All recruited patients had an initial GP visit to confirm knee OA diagnosis. Control patients continued usual GP care, and intervention patients were referred to a centralized care support team (CST) for 12-months. Via telehealth, the CST provided OA education and an agreed OA action plan focused on muscle strengthening, physical activity, and weight management. Primary outcomes were patient self-reported change in knee pain (Numerical Rating Scale [range 0-10; higher score = worse]) and physical function (Knee Injury and Osteoarthritis Outcome Score activities of daily living subscale [range 0-100; higher score = better] at 12 months. Health care cost outcomes included costs of medical visits and prescription medications over the 12-month period. RESULTS: Recruitment targets were not reached. A total of 38 practices and 217 patients were recruited. The intervention improved pain by 0.8 of 10 points (95% confidence interval [95% CI] 0.2, 1.4) and function by 6.5 of 100 points (95% CI 2.3, 10.7), more than usual care at 12 months. Total costs of medical visits and prescriptions were $3,940 (Australian) for the intervention group versus $4,161 for usual care. This difference was not statistically significant. CONCLUSION: The PARTNER model improved knee pain and function more than usual GP care. The magnitude of improvement is unlikely to be clinically meaningful for pain but is uncertain for function.

Feasibility of testing the effectiveness of a theory-informed intervention to reduce imaging for low back pain: a pilot cluster randomised controlled trial.

BACKGROUND: General medical practitioner (GP) recruitment and subsequent data collection in clinical practice are challenging and may limit successful completion of a large-scale trial. The aim of this study was to assess the feasibility of undertaking a cluster randomised controlled trial to test an intervention to reduce non-indicated imaging for low back pain in general medical practice. METHODS: A pilot cluster randomised controlled trial was performed, with recruitment of GPs and randomisation of GP clinics. All GPs attended a training session and were asked to record low back pain codes in electronic medical records for any low back pain presentations. Intervention group GPs were trained in the use of a patient education booklet to be used during low back pain patient visits. Control group GPs provided usual care. Outcomes for the proposed trial were collected to determine feasibility. GP recruitment was assessed as the proportion of GPs approached who consented to participate. Low back pain imaging outcomes were collected from electronic medical records (counts of patients presenting with low back pain) and from Australian healthcare administrative (Medicare) data (counts of imaging use). GP compliance with study procedures was assessed and qualitative data reported. RESULTS: Thirty-four GP clinics were approached, with four participating (12%). At these clinics, 13/19 (68%) GPs consented to participate, and 10/19 (53%) started the study. Outcome data were collected from medical records for all GPs. Three GPs (30%) withdrew consent to access Medicare data, limiting reporting of imaging outcome measures. Three GPs (30%) self-reported low compliance entering low back pain codes. CONCLUSIONS: This pilot cluster randomised controlled trial demonstrated the feasibility of many aspects of a full-scale effectiveness study, while also identifying a number of challenges that need to be resolved. Recommendations related to GP recruitment, study compliance, data collection, and outcome measures were made to increase the success of a future trial.

Low-value care in musculoskeletal health care: Is there a way forward?

BACKGROUND: Low-value care that wastes resources and harms patients is prevalent in health systems everywhere. METHODS: As part of an invited keynote presentation at the Pain in Motion IV conference held in Maastricht, Holland, in May 2022, we reviewed evidence for low-value care in musculoskeletal conditions and discussed possible solutions. RESULTS: Drivers of low-value care are diverse and affect patients, clinicians, and health systems everywhere. We show that low-value care for back pian, neck pain, and osteoarthritis is prevalent in all professional groups involved in caring for people who seek care for these conditions. Implementation efforts that aim to reverse low-value care seem to work better if designed using established conceptual and theoretical frameworks. CONCLUSION: Low-value care is prevalent in the care of people with musculoskeletal conditions. Reducing low-value care requires behaviour change among patients and clinicians as well as in health systems. There is evidence that behaviour change can be facilitated through good conceptual and theoretical frameworks but not convincing evidence that it changes patient outcomes.

Implementing a new physiotherapist-led primary care model for low back pain: a qualitative study of patient and primary care team perspectives.

BACKGROUND: Low back pain (LBP) is one of the most common reasons for primary care visits and is the leading contributor to years lived with disability worldwide. The purpose of this study was to understand the perspectives of patients and primary care team members related to their experiences with a new physiotherapist-led primary care model for LBP. METHODS: We conducted an interpretive description qualitative study. Data were collected using a combination of semi-structured interviews and focus group discussions and analyzed using thematic analysis. Participants included adults (> 18 years of age) with LBP and primary care team members who participated in a physiotherapist-led primary care model for LBP in Kingston, Ontario, Canada. RESULTS: We conducted 18 semi-structured interviews with patients with LBP (10 women; median age of 52) as well as three focus group discussions with a total of 20 primary care team members representing three teams. Four themes (each with sub-themes) were constructed: 1) enhanced primary care delivery for LBP (improved access and engagement in physiotherapy care, improved communication and care integration between the physiotherapist and primary care team, less inappropriate use of healthcare resources); 2) positive patient experiences and perceived outcomes with the new model of care (physiotherapist built therapeutic alliance, physiotherapist provided comprehensive care, improved confidence in managing LBP, decreased impact of pain on daily life); 3) positive primary care team experiences with the new model of care (physiotherapist fit well within the primary care team, physiotherapist provided expertise on LBP for the primary care team, satisfaction in being able to offer a needed service for patients); and 4) challenges implementing the new model of care (challenges with prompt access to physiotherapy care, challenges making the physiotherapist the first contact for LBP, and opportunities to optimize communication between the physiotherapist and primary care team). CONCLUSIONS: A new physiotherapist-led primary care model for LBP was described by patients and primary care team members as contributing to positive experiences and perceived outcomes for patients, primary care team members, and potentially the health system more broadly. Results suggest that this model of care may be a viable approach to support integrated and guideline adherent management of LBP in primary care settings.

A mixed-methods feasibility study of a comorbidity-adapted exercise program for low back pain in older adults (COMEBACK): a protocol.

BACKGROUND: The prevalence of low back pain increases with age and has a profound impact on physical and psychosocial health. With increasing age comes increasing comorbidity, and this also has pronounced health consequences. Whilst exercise is beneficial for a range of health conditions, trials of exercise for low back pain management often exclude older adults. It is currently unknown whether an exercise program for older adults with low back pain, tailored for the presence of comorbidities, is acceptable for participants and primary healthcare providers (PHCPs). Therefore, this mixed-methods study will assess the feasibility of an 8-week comorbidity-adapted exercise program for older people with low back pain and comorbid conditions. METHODS: The 3-phased feasibility study will be performed in a primary healthcare setting. PHCPs will be trained to deliver a comorbidity-adapted exercise program for older people with low back pain and comorbidities. Healthcare-seeking adults > 65 will be screened for eligibility over telephone, with a recruitment target of 24 participants. Eligible participants will attend an initial appointment (diagnostic phase). During this initial appointment, a research assistant will collect patient demographics, self-reported outcome measurement data, and perform a physical and functional examination to determine contraindications and restrictions to an exercise program. During the development phase, PHCPs will adapt the exercise program to the individual and provide patient education. During the intervention phase, there will be two supervised exercise sessions per week, over 8 weeks (total of 16 exercise sessions). Each exercise session will be approximately 60 min in duration. A qualitative evaluation after the last exercise program session will explore the feasibility of the exercise program for participants and PHCPs. Progression criteria will determine the suitability for a fully powered randomised controlled trial. DISCUSSION: This mixed-methods feasibility study will assess an exercise program for older adults with low back pain and comorbidities. Once assessed for feasibility, the exercise program may be tested for effectiveness in a larger, fully powered randomised controlled trial. This information will add to the sparse evidence base on appropriate options for managing back pain in older adults.

General practitioner experiences using a low back pain management booklet aiming to decrease non-indicated imaging for low back pain.

BACKGROUND: Imaging is overused in the management of low back pain, resulting in overdiagnosis, increased healthcare utilisation, and increased costs. Few effective interventions to decrease inappropriate use have been developed and have typically not been developed using behaviour change theory. An intervention to reduce non-indicated imaging for low back pain was developed using behavioural change theory, incorporating a novel low back pain management booklet to facilitate patient education and reassurance. The aim of this study was to assess the adoption and feasibility of use of the developed intervention within clinical practice and to determine appropriate implementation strategies to address identified barriers to use. METHODS: Fourteen general medical practitioners were recruited and trained to use the booklet with low back pain patients over a minimum 5-month period. Quantitative data on use of the booklet were collected and analysed descriptively. Qualitative data on use of the booklet and training session were collected in general medical practitioner interviews and thematically analysed. Barriers to use were identified and mapped to suitable implementation strategies using the Behaviour Change Wheel. RESULTS: Practitioners used the booklet with 73 patients. The booklet was used with 63% of patients presenting with low back pain. Facilitators for using the booklet included patient's requesting imaging and lower practitioner confidence in managing low back pain. Barriers included accessible storage and remembering to use the booklet. Implementation strategies were identified to increase adoption and feasibility of use, including development of a digital version of the booklet. CONCLUSIONS: General medical practitioners reported that the low back pain management booklet and training were useful for clinical practice, particularly with patients requesting imaging. Barriers to use were identified and implementation strategies to address these barriers will be incorporated into future effectiveness studies. This study forms one of a series of studies to thoroughly develop and test an intervention to reduce non-indicated imaging for low back pain; a successful intervention would decrease healthcare costs and improve patient management.

Exploring factors influencing chiropractors' adherence to radiographic guidelines for low back pain using the Theoretical Domains Framework.

BACKGROUND: The inappropriate use of lumbar spine imaging remains common in primary care despite recommendations from evidence-based clinical practice guidelines to avoid imaging in the absence of red flags. This study aimed to explore factors influencing ordering behaviours and adherence to radiographic guidelines for low back pain (LBP) in chiropractors in Newfoundland and Labrador (NL), Canada. METHODS: We conducted two focus groups in December 2018 with chiropractors in different regions of NL (eastern, n = 8; western, n = 4). An interview guide based on the Theoretical Domains Framework (TDF) served to identify perceived barriers to, and enablers of, target behaviours of guideline adherence and managing LBP without X-rays. We conducted thematic analysis of chiropractors' statements into relevant theoretical domains, followed by grouping of similar statements into specific beliefs. Domains key to changing radiographic guideline adherence, LBP imaging behaviours, and/or informing intervention design were identified by noting conflicting beliefs and their reported influence on the target behaviours. RESULTS: Six of the 14 TDF domains were perceived to be important for adherence to radiographic guidelines and managing non-specific LBP without imaging. Participating chiropractors reported varying levels of knowledge and awareness of guidelines for LBP imaging (Knowledge). Many chiropractors based their decision for imaging on clinical presentation, but some relied on "gut feeling" (Memory, attention, and decision processes). While chiropractors thought it was their role to manage LBP without imaging, others believed ordering imaging was the responsibility of other healthcare providers (Social/professional role and identity). Contrasting views were found regarding the negative consequences of imaging or not imaging LBP patients (Beliefs about consequences). Communication was identified as a skill required to manage LBP without imaging (Skills) and a strategy to enable appropriate imaging ordering behaviours (Behavioural regulation). Chiropractors suggested that access to patients' previous imaging and a system that facilitated better interprofessional communication would likely improve their LBP imaging behaviours (Behavioural regulation). CONCLUSION: We identified potential influences, in six theoretical domains, on participating chiropractors' LBP imaging behaviours and adherence to radiographic guidelines. These beliefs may be targets for theory-informed behaviour change interventions aimed at improving these target behaviours for chiropractors in NL.
