What Constitutes "Appropriate Care" for Low Back Pain?: Point-of-Care Clinical Indicators From Guideline Evidence and Experts (the STANDING Collaboration Project)

Clinician approaches to new spine pain cases in primary care: Balance of opioid prescribing and early linkage to exercise therapy and spinal manipulation

RATIONALE, AIMS AND OBJECTIVES

Spine pain (SP) is common and often disabling. Clinical practice guidelines discourage opioid treatment and outline the value of varied nonpharmacologic therapies (NPTs). This study elucidates the amount of variability in primary-care clinicians' (PCPs') prescribing of opioids and in their cases' receipt of the two most common NPTs (exercise therapy and spinal manipulation).

METHOD

The design was a retrospective cohort study examining variation in the treatment of PCPs' new SP cases, classified by receipt of (a) prescription of an opioid at the initial visit; (b) exercise therapy and/or spinal manipulation within 30 days of initial visit. The study was set in the primary care clinics at military treatment facilities of the US Military Health System in the period between October 2011 and September 2016.

RESULTS

The majority of cases did not receive a study treatment (66.3%); 19.6% of cases received only NPT within 30 days of initial visit; 11.5% were prescribed only an opioid at the initial visit with receipt of both NPT and opioid during early treatment rare (2.6%). Exercise therapy within 30 days exhibited more than a twofold difference in interquartile percentile rates (IQR) (median provision 15.8%, IQR 9.8%-22.1%). The other treatments exhibited even greater variation; specifically, spinal manipulation (median 8.5%, IQR 3.3%-15.8%), and opioid at initial visit (median 10.3%, IQR 4.4%-18.2%). The availability of physical therapists and doctors of chiropractic had significant association with several clinical provision rates.

CONCLUSION

Among providers of spine care for a sample of Army soldiers, there was substantial variation in the early provision of exercise therapy, spinal manipulation, and opioid prescriptions. The magnitude of the case-mix adjusted variation and its association with facility availability of providers suggests that quality of care initiatives may help reduce this variation.

A critical review of the role of manual therapy in the treatment of individuals with low back pain

The number of low back pain (LBP) cases is projected to increase to more than 800 million by 2050. To address the substantial burden of disease associated with this rise in prevalence, effective treatments are needed. While clinical practice guidelines (CPG) consistently recommend non-pharmacological therapies as first-line treatments, recommendations regarding manual therapy (MT) in treating low back pain vary. The goal of this narrative review was to critically summarize the available evidence for MT behind these recommendations, to scrutinize its mechanisms of action, and propose some actionable steps for clinicians on how this knowledge can be integrated into a person-centered approach. Despite disparate recommendations from CPG, MT is as effective as other available treatments and may be offered to patients with LBP, especially as part of a treatment package with exercise and education. Most of the effects of MT are not specific to the technique. MT and other interventions share several mechanisms of action that mediate treatment success. These mechanisms can encompass patients' expectations, prior experiences, beliefs and convictions, epistemic trust, and nonspecific contextual effects. Although MT is safer than opioids for patients with LBP, this alone is insufficient. Our goal is to encourage clinicians to shift away from outdated and refuted ideas in MT and embrace a person-centered approach rooted in a comprehensive biopsychosocial framework while incorporating patients' beliefs, addressing illness behaviors, and seeking to understand each patient's journey.

Developing an initial set of quality indicators for chiropractic care: a scoping review

BACKGROUND

Quality indicators are standardized, evidence-based measures of health care quality. Currently, there is no basic set of quality indicators for chiropractic care published in peer-reviewed literature. The goal of this research is to develop a preliminary set of quality indicators, measurable with administrative data.

METHODS

We conducted a scoping review searching PubMed/MEDLINE, CINAHL, and Index to Chiropractic Literature databases. Eligible articles were published after 2011, in English, developing/reporting best practices and clinical guidelines specifically developed for, or directly applicable to, chiropractic care. Eligible non-peer-reviewed sources such as quality measures published by the Centers for Medicare and Medicaid Services and the Royal College of Chiropractors quality standards were also included. Following a stepwise eligibility determination process, data abstraction identified specific statements from included sources that can conceivably be measured with administrative data. Once identified, statements were transformed into potential indicators by: 1) Generating a brief title and description; 2) Documenting a source; 3) Developing a metric; and 4) Assigning a Donabedian category (structure, process, outcome). Draft indicators then traversed a 5-step assessment: 1) Describes a narrowly defined structure, process, or outcome; 2) Quantitative data can conceivably be available; 3) Performance is achievable; 4) Metric is relevant; 5) Data are obtainable within reasonable time limits. Indicators meeting all criteria were included in the final set.

RESULTS

Literature searching revealed 2562 articles. After removing duplicates and conducting eligibility determination, 18 remained. Most were clinical guidelines (n = 10) and best practice recommendations (n = 6), with 1 consensus and 1 clinical standards development study. Data abstraction and transformation produced 204 draft quality indicators. Of those, 57 did not meet 1 or more assessment criteria. After removing duplicates, 70 distinct indicators remained. Most indicators matched the Donabedian category of process (n = 35), with 31 structure and 4 outcome indicators. No sources were identified to support indicator development from patient perspectives.

CONCLUSIONS

This article proposes a preliminary set of 70 quality indicators for chiropractic care, theoretically measurable with administrative data and largely obtained from electronic health records. Future research should assess feasibility, achieve stakeholder consensus, develop additional indicators including those considering patient perspectives, and study relationships with clinical outcomes.

Fostering equitable change in health services: Using critical reflexivity to challenge dominant discourses in low back pain care in Australia

OBJECTIVES

Justice and equity-focused practices in health services play a critical but overlooked role in low back pain (LBP) care. Critical reflexivity - the ability to examine and challenge power relations, and broader social issues embedded in everyday life - can be a useful tool to foster practices that are more socially just. No research has yet explored this approach in back pain health services. This study sought to understand how clinicians construct LBP in relation to broader socio-cultural-political aspects of care and explore if those constructions changed when clinicians engaged with critically reflexive dialogues with researchers.

METHODS

Using critical discourse analysis methods, this qualitative study explored institutionalised patterns of knowledge in the construction of LBP care. We conducted 22 critically reflexive dialogues with 29 clinicians from two health services in Australia - a private physiotherapy clinic and a public multidisciplinary pain clinic.

RESULTS

Our analyses suggested that clinicians and services often constructed LBP care at an individual level. This dominant individualistic discourse constrained consideration of justice-oriented practices in the care of people with LBP. Through dialogues, discursive constructions of LBP care expanded to incorporate systems and health service workplace practices. This expansion fostered more equitable clinical and service practices - such as assisting patients to navigate health care systems, considering patients' socioeconomic circumstances when developing treatment plans, encouraging staff discussion of possible systemic changes to enhance justice, and fostering a more inclusive workplace culture. Although such expansions faced challenges, incorporating broader discourses enabled recommendations to address LBP care inequities.

CONCLUSIONS

Critical reflexivity can be a tool to foster greater social justice within health services. By expanding constructions of LBP care beyond individuals, critical reflexive dialogues can foster discussion and actions towards more equitable workplace cultures, services and systems.

Mézières Method as a practice of embodiment in patients with low back pain: a mixed study

INTRODUCTION

The objectives of this study were to determine the effects of the Mézières Method (MM) on pain and disability related to low back pain (LBP), compared to a program of heat, massage and exercise, and to understand the meaning of the bodily experience with the MM.

PATIENTS AND METHODS

Mixed methods convergent parallel design, combining an equivalent randomized clinical trial with a qualitative phenomenological approach. Sixty-one participants aged 18-65 years with chronic non-specific LBP lasting more than 3 months. Patients were randomized into two groups: the MM group (n = 29) and the comparison group (CG) who received heat, massage plus flexibility and strengthening exercises (n = 31). MM and CG participants underwent 10 one-hour physical therapy sessions over a 5-week period and were evaluated three times: pre-intervention, post-intervention and follow-up at 6 weeks after the end of treatment.

RESULTS

Both groups reported positive effects on LBP . MM group showed superior effects in pain relief in the short term (Cohen's D 0.80; p = 0.004). Participants interpreted the interaction with the MM as a teaching-learning process that allowed body awareness.

CONCLUSION

Both treatment were similarly beneficial but MM had superior effects on pain in the short term. MM is perceived by the participants as a teaching-learning process focused on body awareness that facilitate effective management of LBP.

A Procedure for Measuring Anterior Scalene Morphology and Quality with Ultrasound Imaging: An Intra- and Inter-rater Reliability Study

OBJECTIVE

Ultrasound (US) imaging is an essential tool for clinicians because of its cost-effectiveness and accessibility for assessing multiple muscle metrics including muscle quality, size and shape. Although previous studies highlighted the importance of the anterior scalene muscle (AS) in patients with neck pain, studies analyzing the reliability of US measurements for this muscle are lacking. This study aimed to develop a protocol for assessing AS muscle shape and quality measured with US and investigating its intra- and inter-examiner reliability.

METHODS

Through use of a linear transducer, B-mode images of the anterolateral neck region at the C7 level were acquired in 28 healthy volunteers by two examiners (one experienced and one novel). Cross-sectional area, perimeter, shape descriptors and mean echo-intensity were measured twice by each examiner in randomized order. Intra-class correlation coefficients (ICCs), standard errors of measurement and minimal detectable changes were calculated.

RESULTS

Results indicated no muscle side-to-side asymmetries (p > 0.05). Gender differences were found for muscle size (p < 0.01), but muscle shape and brightness were comparable (p > 0.05). Intra-examiner reliability was good to excellent for all metrics for the experienced and (ICC >0.846) and novel (ICC >780) examiners. Although inter-examiner reliability was good for most of the metrics (ICC >0.709), the estimates for assessing solidity and circularity were unacceptable (ICC <0.70).

CONCLUSION

This study found that the described ultrasound procedure for locating and measuring anterior scalene muscle morphology and quality is highly reliable in asymptomatic individuals.

Recurrence of low back pain: A difficult outcome to predict. Development and validation of a multivariable prediction model for recurrence in patients recently recovered from an episode of non-specific low back pain

BACKGROUND

Recurrence of low back pain (LBP) is common. If clinicians could identify an individual's risk of recurrence, this would enhance clinical decision-making and tailored patient care.

OBJECTIVE/DESIGN

To develop and validate a simple tool to predict the probability of a recurrence of LBP by 3- or 12-months following recovery.

METHODS

Data utilised for the prediction model development came from a prospective inception cohort study of participants (n = 250) recently recovered from LBP, who had sought care from chiropractic or physiotherapy services. The outcome measure was a recurrence of activity-limiting LBP. Candidate predictor variables (e.g., basic demographics, LBP history, levels of physical activity, etc) collected at baseline were considered for inclusion in a multivariable Cox model. The model's performance was tested in a separate validation dataset of participants (n = 261) involved in a randomised controlled trial investigating exercise for the prevention of LBP recurrences.

RESULTS

The final model included the number of previous episodes, total sitting time, and level of education. In the development sample, discrimination was acceptable (Harrell's C-statistic = 0.61, 95% CI, 0.59-0.62), but in the validation sample, discrimination was poor (0.56, 95% CI, 0.54-0.58). Calibration of the model in the validation dataset was acceptable at 3 months but was less precise at 12 months.

CONCLUSION

The developed prediction model, which included number of previous episodes, total sitting time, and level of education, did not perform adequately in the validation sample to recommend its use in clinical practice. Predicting recurrence of LBP in clinical practice remains challenging.

A Systems Approach for Assessing Low Back Pain Care Quality in Veterans Health Administration Chiropractic Visits: A Cross-Sectional Analysis

OBJECTIVE

The purpose of this study was to explore a systemwide process for assessing components of low back pain (LBP) care quality in Veterans Health Administration (VHA) chiropractic visits using electronic health record (EHR) data.

METHODS

We performed a cross-sectional quality improvement project. We randomly sampled 1000 on-station VHA chiropractic initial visits occurring from October 1, 2017, to September 30, 2018, for patients with no such visits within the prior 12 months. Characteristics of LBP visits were extracted from VHA national EHR data via structured data queries and manual chart review. We developed quality indicators for history and/or examination and treatment procedures using previously published literature and calculated frequencies of visits meeting these indicators. Visits meeting our history and/or examination and treatment indicators were classified as "high-quality" visits. We performed a regression analysis to assess associations between demographic/clinical characteristics and visits meeting our quality criteria.

RESULTS

There were 592 LBP visits identified. Medical history, physical examination, and neurologic examination were documented in 76%, 77%, and 63% of all LBP visits, respectively. Recommended treatments, such as any manipulation, disease-specific education/advice, and therapeutic exercise, occurred in 75%, 69%, and 40% of chronic visits (n = 383), respectively. In acute/subacute visits (n = 37), any manipulation (92%), manual soft tissue therapy (57%), and disease-specific advice/education (54%) occurred most frequently. Female patients and those with a neck pain comorbid diagnosis were significantly less likely to have a "high-quality" visit, while other regression associations were non-significant.

CONCLUSION

This study explored a systemwide process for assessing components of care quality in VHA chiropractic visits for LBP. These results produced a potential framework for uniform assessment of care quality in VHA chiropractic visits for LBP and highlight potential areas for improvements in LBP care quality assessments.

Research designs and instruments to detect physiotherapy overuse of low-value care services in low back pain management: a scoping review

BACKGROUND

The provision of low-value physiotherapy services in low back pain management is a known but complex phenomenon. Thus, this scoping review aims to systematically map existing research designs and instruments of the field in order to discuss the current state of research methodologies and contextualize results to domains and perspectives of a referred low-value care typology. Ultimately, results will be illustrated and transferred to conditions of the German health care setting as care delivery conditions of physiotherapy in Germany face unique particularities.

METHODS

The development of this review is guided by the analysis framework of Arksey and O'Malley. A two-stage, audited search strategy was performed in Medline (PubMed), Web of Science, and google scholar. All types of observational studies were included. Identified articles needed to address a pre-determined population, concept, and context framework and had to be published in English or German language. The publication date of included articles was not subject to any limitation. The applied framework to assess the phenomenon of low-value physiotherapy services incorporated three domains (care effectiveness; care efficiency; patient alignment of care) and perspectives (provider; patient; society) of care.

RESULTS

Thirty-three articles met the inclusion criteria. Seventy-nine percent of articles focused on the appropriateness of physiotherapeutic treatments, followed by education and information (30%), the diagnostic process (15%), and goal-setting practice (12%). Study designs were predominantly cross-sectional (58%). Data sources were mainly survey instruments (67%) of which 50% were self-developed. Most studies addressed the effectiveness domain of care (73%) and the provider perspective (88%). The perspective of patient alignment was assessed by 6% of included articles. None of included articles assessed the society perspective. Four methodical approaches of included articles were rated to be transferrable to Germany.

CONCLUSION

Identified research on low-value physiotherapy care in low back pain management was widely unidimensional. Most articles focused on the effectiveness domain of care and investigated the provider perspective. Most measures were indirectly and did not monitor low-value care trends over a set period of time. Research on low-value physiotherapy care in secondary care conditions, such as Germany, was scarce.

Correlation between Body Composition and Inter-Examiner Errors for Assessing Lumbar Multifidus Muscle Size, Shape and Quality Metrics with Ultrasound Imaging

Ultrasound imaging (US) is widely used in several healthcare disciplines (including physiotherapy) for assessing multiple muscle metrics such as muscle morphology and quality. Since measuring instruments are required to demonstrate their reliability, accuracy, sensitivity, and specificity prior to their use in clinical and research settings, identifying factors affecting their diagnostic accuracy is essential. Since previous studies analyzed the impact of sociodemographic but not body composition characteristics in US errors, this study aimed to assess whether body composition metrics are correlated with ultrasound measurement errors. B-mode images of the lumbar multifidus muscle at the fifth lumbar vertebral level (L5) were acquired and analyzed in 49 healthy volunteers by two examiners (one experienced and one novel). Cross-sectional area, muscle perimeter and mean echo intensity were calculated bilaterally. A multivariate correlation matrix was calculated for assessing the inter-examiner differences with body composition metrics. Results demonstrated excellent reliability (intraclass correlation coefficient, ICC > 0.9) for assessing the muscle cross-sectional area and perimeter, and good reliability for assessing the muscle shape and mean echo intensity (ICC > 0.7). Inter-examiner errors for estimating muscle size were correlated with participants' age (p value, p < 0.01), weight (p < 0.05), total and trunk lean mass (both, p < 0.01) and water volume (p < 0.05). Greater shape descriptors and mean brightness disagreements were correlated with older ages (p < 0.05) and total lean mass (p < 0.05). No correlations between age and body composition metrics were found (p > 0.05). This study found US to be a reliable tool for assessing muscle size, shape and mean brightness. Although aging showed no correlations with body composition changes in this sample, it was the main factor correlated with US measurement errors.

Anatomical analysis of the C2 pedicle in patients with basilar invagination

PURPOSE

To evaluate and describe the morphologic features of the C2 pedicle in patients with basilar invagination (BI) for informing the placement of pedicle screws. C2 pedicle screw placement is an important surgical technique for the treatment of atlantoaxial instability in patients with BI. However, no systematic and comprehensive anatomical study of the C2 pedicle in patients with BI has been reported.

METHODS

The data from 100 patients diagnosed with BI (BI group) and 100 patients without head or cervical disease (control group) were included in the study. Radiographic parameters, including the pedicle width, length, height, transverse angle, lamina angle, and superior angle, were measured and analyzed on CT images. After summary analysis, the effect of C2-3 congenital fusion on C2 pedicle deformity in patients with BI was also investigated.

RESULTS

The width, length, and height of the C2 pedicle of the BI patients were smaller than those of the control group. The pedicle cancellous bone was smaller in the BI group, while no significant difference in cortical bone was observed. In total, 44% of the pedicles were smaller than 4.5 mm in the BI group. Patients with C2-3 congenital fusion presented with smaller pedicle transverse angles and larger pedicle superior angles than those without fusion. Wide variations in the left and right angles of the pedicle were observed in the BI group with atlantoaxial dislocation or atlantooccipital fusion.

CONCLUSION

The C2 pedicle in the BI group was thinner than that in the control group due to a smaller cortical bone. Cases of C2-3 congenital fusion, atlantoaxial dislocation, and atlantooccipital fusion displayed variation in the angle of the C2 pedicle.
