Disability burden due to musculoskeletal conditions and low back pain in Australia: findings from GBD 2019.

BACKGROUND: To report the national prevalence, years lived with disability (YLDs) and attributable risk factors for all musculoskeletal conditions and separately for low back pain (LBP), as well as compare the disability burden related to musculoskeletal with other health conditions in Australia in 2019. METHODS: Global Burden of Disease (GBD) 2019 study meta-data on all musculoskeletal conditions and LBP specifically were accessed and aggregated. Counts and age-standardised rates, for both sexes and across all ages, for prevalence, YLDs and attributable risk factors are reported. RESULTS: In 2019, musculoskeletal conditions were estimated to be the leading cause of YLDs in Australia (20.1%). There were 7,219,894.5 (95% UI: 6,847,113-7,616,567) prevalent cases of musculoskeletal conditions and 685,363 (95% UI: 487,722-921,471) YLDs due to musculoskeletal conditions. There were 2,676,192 (95% UI: 2,339,327-3,061,066) prevalent cases of LBP and 298,624 (95% UI: 209,364-402,395) YLDs due to LBP. LBP was attributed to 44% of YLDs due to musculoskeletal conditions. In 2019, 22.3% and 39.8% of YLDs due to musculoskeletal conditions and LBP, respectively, were attributed to modifiable GBD risk factors. CONCLUSIONS: The ongoing high burden due to musculoskeletal conditions impacts Australians across the life course, and in particular females and older Australians. Strategies for integrative and organisational interventions in the Australian healthcare system should support high-value care and address key modifiable risk factors for disability such as smoking, occupational ergonomic factors and obesity.

BAck complaints in the elders - chiropractic (BACE-C): protocol of an international cohort study of older adults with low back pain seeking chiropractic care.

BACKGROUND: Low back pain is a common condition among older adults that significantly influences physical function and participation. Compared to their younger counterparts, there is limited information available about the clinical course of low back pain in older people, in particularly those presenting for chiropractic care. Improving our understanding of this patient population and the course of their low back pain may provide input for studies researching safer and more effective care than is currently provided. OBJECTIVES: The primary objectives are to examine the clinical course over one year of pain intensity, healthcare costs and pain, functional status and recovery rates of low back pain in people 55 years and older who visit a chiropractor for a new episode of low back pain. METHODS: An international prospective, multi-center cohort study with one-year follow-up. Chiropractic practices are to be recruited in the Netherlands, Sweden, United Kingdom and Australia. Treatment will be left to the discretion of the chiropractor. Inclusion/Exclusion criteria: Patients aged 55 and older who consult a chiropractor for a new episode of low back pain, meaning low back pain for the first time or those patients who have not been to a chiropractor in the previous six months. This is independent of whether they have seen another type of health care provider for the current episode. Patients who are unable to complete the web-based questionnaires because of language restrictions or those with computer literacy restrictions will be excluded as well as those with cognitive disorders. In addition, those with a suspected tumor, fracture, infection or any other potential red flag or condition considered to be a contraindication for chiropractic care will be excluded. Data will be collected using online questionnaires at baseline, and at 2 and 6 weeks and at 3, 6, 9 and 12 months. DISCUSSION: This study, to our knowledge, is the first large-scale, prospective, multicenter, international cohort study to be conducted in a chiropractic setting to focus on older adults with low back pain consulting a chiropractor. By understanding the clinical course, satisfaction and safety of chiropractic treatment of this common debilitating condition in the aged population, this study will provide input for informing future clinical trials.

Imaging use for low back pain by Ontario primary care clinicians: protocol for a mixed methods study - the Back ON study.

BACKGROUND: At any one time, one in every five Canadians has low back pain (LBP), and LBP is one of the most common health problems in primary care. Guidelines recommend that imaging not be routinely performed in patients presenting with LBP without signs or symptoms indicating a potential pathological cause. Yet imaging rates remain high for many patients who present without such indications. Inappropriate imaging can lead to inappropriate treatments, results in worse health outcomes and causes harm from unnecessary radiation. There is a need to understand the extent of, and factors contributing to, inappropriate imaging for LBP, and to develop effective strategies that target modifiable barriers and facilitators. The primary study objectives are to determine: 1) The rate of, and factors associated with, inappropriate lumbar spine imaging (x-ray, CT scan and MRI) for people with non-specific LBP presenting to primary care clinicians in Ontario; 2) The barriers and facilitators to reduce inappropriate imaging for LBP in primary care settings. METHODS: The project will comprise an inception cohort study and a concurrent qualitative study. For the cohort study, we will recruit 175 primary care clinicians (50 each from physiotherapy and chiropractic; 75 from family medicine), and 3750 patients with a new episode of LBP who present to these clinicians. Clinicians will collect data in the clinic, and each participant will be tracked for 12 months using Ontario health administrative and self-reported data to measure diagnostic imaging use and other health outcomes. We will assess characteristics of the clinicians, patients and encounters to identify variables associated with inappropriate imaging. In the qualitative study we will conduct in-depth interviews with primary care clinicians and patients. DISCUSSION: This will be the first Canadian study to accurately document the extent of the overuse of imaging for LBP, and the first worldwide to include data from the main healthcare professions offering primary care for people with LBP. This study will provide robust information about rates of inappropriate imaging for LBP, along with factors associated with, and an understanding of, potential reasons for inappropriate imaging.

Current evidence for spinal X-ray use in the chiropractic profession: a narrative review.

The use of routine spinal X-rays within chiropractic has a contentious history. Elements of the profession advocate for the need for routine spinal X-rays to improve patient management, whereas other chiropractors advocate using spinal X-rays only when endorsed by current imaging guidelines. This review aims to summarise the current evidence for the use of spinal X-ray in chiropractic practice, with consideration of the related risks and benefits. Current evidence supports the use of spinal X-rays only in the diagnosis of trauma and spondyloarthropathy, and in the assessment of progressive spinal structural deformities such as adolescent idiopathic scoliosis. MRI is indicated to diagnose serious pathology such as cancer or infection, and to assess the need for surgical management in radiculopathy and spinal stenosis. Strong evidence demonstrates risks of imaging such as excessive radiation exposure, overdiagnosis, subsequent low-value investigation and treatment procedures, and increased costs. In most cases the potential benefits from routine imaging, including spinal X-rays, do not outweigh the potential harms. The use of spinal X-rays should not be routinely performed in chiropractic practice, and should be guided by clinical guidelines and clinician judgement.

Identifying research priorities around psycho-cognitive and social factors for recovery from hip fractures: An international decision-making process.

Hip fractures rank in the top ten disabling conditions worldwide. With an ageing population, this public health problem is expected to increase. Despite the success of surgery for hip fractures and the extensive health services utilisation, health outcomes are often poor. Considering the recovery process as multifactorial and intervening to address all relevant factors may improve recovery rates. However, we need first to fully understand the factors contributing to recovery after hip fractures, including psycho-cognitive and social factors. The purpose of this study was to identify future research priorities for understanding the role of psycho-cognitive and social factors in the recovery process for community-dwelling older adults after hip fracture and to survey world experts to confirm the identified priorities. METHODS: This was a two-stage process. First, a workshop of international experts in hip fracture care (researchers and clinician-scientists) was held in 2016 in Montreal, Quebec, Canada. Using Nominal Group Technique accompanied by Multi-voting Technique, workshop attendees identified the most important future research areas for psycho-cognitive and social factors contributing to recovery after hip fractures. Second, an online survey of the International Fragility Fracture Network (FFN), which includes researchers and clinicians interested in fragility fractures, followed the meeting. The survey respondents reviewed and added to priorities from the first stage and then ranked the top priorities. RESULTS: Twenty-three experts participated in the meeting (from five countries) and 152 participants (from 29 countries) responded to the survey. Top priorities for the psycho-cognitive domain were preventing and treating in-hospital delirium; comparing the effectiveness of targeted versus multifactorial interventions; studying interactions between psycho-cognitive, social, and environmental factors in the recovery process; and modifying the environment to enhance patients' cognitive reserves. Top priorities for the social domain were understanding the role of social factors in the recovery process; understanding patients' perspectives on important social factors; identifying components of social support relevant to recovery; understanding attitudes towards patients with hip fractures among all stakeholders; and understanding the social support needs for caregivers. CONCLUSION: A set of future research priorities to understand the role of psycho-cognitive and social factors has been developed and confirmed through a rigorous international decision-making process. These priorities offer valuable guidance for researchers, scientific bodies, and funding agencies.

Peri-Operative Chemotherapy for Bladder Cancer: A Survey of Providers to Determine Barriers and Enablers.

BACKGROUND: Utilization of chemotherapy for patients with muscle-invasive bladder cancer (MIBC) is low. In earlier qualitative work we used the Theoretical Domains Framework (TDF) to determine barriers and enablers of chemotherapy use. In this project we aimed to determine the prevalence of these barriers and enablers in Canadian physicians. METHODS: Practicing Canadian urologists, medical oncologists (MOs) and radiation oncologists (ROs) participated in a specialty-specific web-based quantitative survey to assess potential barriers and enablers to chemotherapy use. Survey questions were developed that were thematically mapped to TDF domains. Logistic regression was used to identify TDF domains associated with high referral/use of chemotherapy. RESULTS: 110 urologists, 47 MOs and 43 ROs completed the survey; response rates were 20%, 35% and 31% respectively. The mean reported survival gain associated with neoadjuvant chemotherapy (NACT) was 9%, 8%, and 7% for urologists, MOs, and ROs respectively. Among participating urologists, the TDF domains 'social and professional role' (OR = 16.5, 95% CI 4.6-59.2), 'social influences' (OR = 5.7, 95% CI 2.4-13.4) 'beliefs about consequences' (OR = 4.9, 95% CI 1.8-13.3) and 'memory, attention and decision-making' (OR = 0.50, 95% CI 0.27-0.91) were associated with MO referral rates. Among MOs, the TDF domains 'behavioural regulation', 'social influences', and 'social and professional role' were associated with greater use of chemotherapy (p < 0.05). No TDF domains were associated with RO referral to MO. CONCLUSIONS: We have identified several factors associated with referral/use of chemotherapy for MIBC. Optimization of multidisciplinary patient care needs to be considered when designing future interventions to close the gap between evidence and practice.

A Qualitative Study of Doctors of Chiropractic in a Nova Scotian Practice-based Research Network: Barriers and Facilitators to the Screening and Management of Psychosocial Factors for Patients With Low Back Pain.

OBJECTIVES: This study aimed to assess chiropractors' awareness of clinical practice guidelines for low back pain and to identify barriers and facilitators to the screening and management of psychosocial factors in patients with low back pain. METHODS: This qualitative study used semi-structured interviews informed by the Theoretical Domains Framework with 10 Nova Scotian chiropractors who were members of a practice-based research network. RESULTS: The participants correctly identified what the guidelines generally recommend and described the value of psychosocial factors; however, none of the participants could name specific clinical practice guidelines for low back pain. We identified 6 themes related to barriers and facilitators for chiropractors screening and managing psychosocial factors. The themes revolved around the participants' desire to fulfill patients' anatomy-focused treatment expectations and a perceived lack of training for managing psychosocial factors. Participants had concerns about going beyond the chiropractic scope of practice, and they perceived a lack of practical psychosocial screening and management resources. Social factors, such as the influence of other health care practitioners, were reported as both barriers and facilitators to screening and managing psychosocial factors. CONCLUSIONS: The participants in this study reported that they mostly treated with an anatomical and biomechanical focus and that they did not always address psychosocial factors identified in their patients with low back pain. Although these findings are limited to Nova Scotian chiropractors, the barriers identified appeared to be potentially modifiable and could be considered in other groups. Low-cost interventions, such as continuing education using evidence-informed behavior change techniques, could be considered to address these barriers.

Perioperative chemotherapy for bladder cancer: A qualitative study of physician knowledge, attitudes, and behaviour.

INTRODUCTION: Use of chemotherapy for muscle-invasive bladder cancer (MIBC) is known to be low. To understand factors driving practice we use the Theoretical Domains Framework (TDF) to identify barriers and enablers of chemotherapy use. METHODS: A convenience sample of Canadian urologists, medical oncologists (MOs), and radiation oncologists (ROs) participated in individual, semi-structured, one-hour telephone interviews. An interview guide was developed using the TDF to assess potential barriers and enablers of chemotherapy use. Interviews were recorded and transcribed. Two investigators independently identified barriers and enablers and assigned them to specific themes. Participant recruitment continued until saturation. RESULTS: A total of 71 physicians were invited to participate and 34 (48%) agreed to be interviewed: 13 urologists, 10 MOs, and 11 ROs. We identified the following barriers to the use of chemotherapy (relevant TDF domains in parentheses): 1) belief that the benefits of chemotherapy are not clinically important (beliefs about consequences); 2) inadequate multidisciplinary collaboration (environmental context and resources); 3) absence of "champions" advocating the use of chemotherapy (social and professional role); and 4) a lack of organizational clarity/policy regarding the referral process (environmental context and resources). The predominant enablers identified included: 1) "champions" who believe in the value of chemotherapy (social and professional role); 2) urologists who refer all patients to MO (behavioural regulation; memory, attention, and decision-making); and 3) system-level factors, including automatic multidisciplinary referral (environmental context and resources). CONCLUSIONS: We have identified several system-level factors associated with delivery of chemotherapy. Behaviour change interventions should optimize multidisciplinary care of patients with MIBC. PATIENT SUMMARY: Despite the fact that chemotherapy before or after surgery improves survival of patients with bladder cancer, several studies have shown that many patients in routine practice are not treated. In this study, we identify important system-level and physician-level factors that must be considered in efforts to improve patient care.

Expectancy after the first treatment and response to acupuncture for menopausal hot flashes.

BACKGROUND: Evidence on the impact of expectancy on acupuncture treatment response is conflicting. OBJECTIVES: This secondary analysis of a randomized sham-controlled trial on acupuncture for menopausal hot flashes investigated whether treatment expectancy score was associated with hot flash score at end-of-treatment. Secondary analyses investigated whether there were associations between other pre-specified factors and hot flash score. STUDY DESIGN: Women experiencing moderately-severe hot flashes were randomized to receive 10 sessions of real or sham acupuncture over eight weeks. Hot flash score was collected using a seven-day hot flash diary, and expectancy using the modified Credibility and Expectancy Questionnaire immediately after the first treatment. Linear mixed-effects models with random intercepts were used to identify associations between expectancy score and hot flash score at end-of-treatment. Regression was also used to identify associations between pre-specified factors of interest and hot flash score. Because there was no difference between real and sham acupuncture for the primary outcome of hot flash score, both arms were combined in the analysis. RESULTS: 285 women returned the Credibility and Expectancy Questionnaire, and 283 women completed both expectancy measures. We found no evidence for an association between expectancy and hot flash score at end-of-treatment for individual cases in either acupuncture or sham group. Hot flash scores at end-of-treatment were 8.1 (95%CI, 3.0 to 13.2; P = 0.002) points lower in regular smokers compared to those who had never smoked, equivalent to four fewer moderate hot flashes a day. CONCLUSION: In our study of acupuncture for menopausal hot flashes, higher expectancy after the first treatment did not predict better treatment outcomes. Future research may focus on other determinants of outcomes in acupuncture such as therapist attention. The relationship between smoking and hot flashes is poorly understood and needs further exploration.

Bladder-sparing radiotherapy for muscle-invasive bladder cancer: A survey of providers to determine barriers and enablers.

BACKGROUND: To understand barriers and enablers to use of curative-intent radiotherapy (RT) for muscle-invasive bladder cancer using the Theoretical Domains Framework (TDF). METHODS: Canadian urologists, radiation oncologists (ROs) and medical oncologists (MOs) participated in a web-based survey to assess barriers and enablers to use of RT. Survey questions were thematically mapped to TDF domains. Logistic regression was used to identify TDF domains associated with high referral/use of RT. RESULTS: 64 urologists, 29 ROs and 26 MOs participated. Participants reported comparable survival at five years with cystectomy (51%) and RT with concurrent chemotherapy (50%). Despite this, participants reported low RT referral/treatment rates: Urologists referred a median of 2/10 patients to RO; ROs treated a median of 5/10 patients referred; and MOs referred a median of 2/8 patients not referred to RO by urology. Among urologists, the TDF domains 'beliefs about consequences' (OR=8.1, 95% CI 1.5-44.9), 'social and professional role' (OR=11.2, 95% CI 2.3-53.6) and 'environmental context and resources' (OR=5.9, 95% CI 1.5-23.3) were associated with higher rates of RO referral. CONCLUSIONS: We have identified factors associated with referral for RT among patients with bladder cancer. These factors should be addressed as part of a concerted effort to increase utilization of RT.

Acupuncture for Menopausal Hot Flashes: A Randomized Trial.

BACKGROUND: Hot flashes (HFs) affect up to 75% of menopausal women and pose a considerable health and financial burden. Evidence of acupuncture efficacy as an HF treatment is conflicting. OBJECTIVE: To assess the efficacy of Chinese medicine acupuncture against sham acupuncture for menopausal HFs. DESIGN: Stratified, blind (participants, outcome assessors, and investigators, but not treating acupuncturists), parallel, randomized, sham-controlled trial with equal allocation. (Australia New Zealand Clinical Trials Registry: ACTRN12611000393954). SETTING: Community in Australia. PARTICIPANTS: Women older than 40 years in the late menopausal transition or postmenopause with at least 7 moderate HFs daily, meeting criteria for Chinese medicine diagnosis of kidney yin deficiency. INTERVENTIONS: 10 treatments over 8 weeks of either standardized Chinese medicine needle acupuncture designed to treat kidney yin deficiency or noninsertive sham acupuncture. MEASUREMENTS: The primary outcome was HF score at the end of treatment. Secondary outcomes included quality of life, anxiety, depression, and adverse events. Participants were assessed at 4 weeks, the end of treatment, and then 3 and 6 months after the end of treatment. Intention-to-treat analysis was conducted with linear mixed-effects models. RESULTS: 327 women were randomly assigned to acupuncture (n = 163) or sham acupuncture (n = 164). At the end of treatment, 16% of participants in the acupuncture group and 13% in the sham group were lost to follow-up. Mean HF scores at the end of treatment were 15.36 in the acupuncture group and 15.04 in the sham group (mean difference, 0.33 [95% CI, -1.87 to 2.52]; P = 0.77). No serious adverse events were reported. LIMITATION: Participants were predominantly Caucasian and did not have breast cancer or surgical menopause. CONCLUSION: Chinese medicine acupuncture was not superior to noninsertive sham acupuncture for women with moderately severe menopausal HFs.

Effectiveness of interventions designed to reduce the use of imaging for low-back pain: a systematic review.

BACKGROUND: Rates of imaging for low-back pain are high and are associated with increased health care costs and radiation exposure as well as potentially poorer patient outcomes. We conducted a systematic review to investigate the effectiveness of interventions aimed at reducing the use of imaging for low-back pain. METHODS: We searched MEDLINE, Embase, CINAHL and the Cochrane Central Register of Controlled Trials from the earliest records to June 23, 2014. We included randomized controlled trials, controlled clinical trials and interrupted time series studies that assessed interventions designed to reduce the use of imaging in any clinical setting, including primary, emergency and specialist care. Two independent reviewers extracted data and assessed risk of bias. We used raw data on imaging rates to calculate summary statistics. Study heterogeneity prevented meta-analysis. RESULTS: A total of 8500 records were identified through the literature search. Of the 54 potentially eligible studies reviewed in full, 7 were included in our review. Clinical decision support involving a modified referral form in a hospital setting reduced imaging by 36.8% (95% confidence interval [CI] 33.2% to 40.5%). Targeted reminders to primary care physicians of appropriate indications for imaging reduced referrals for imaging by 22.5% (95% CI 8.4% to 36.8%). Interventions that used practitioner audits and feedback, practitioner education or guideline dissemination did not significantly reduce imaging rates. Lack of power within some of the included studies resulted in lack of statistical significance despite potentially clinically important effects. INTERPRETATION: Clinical decision support in a hospital setting and targeted reminders to primary care doctors were effective interventions in reducing the use of imaging for low-back pain. These are potentially low-cost interventions that would substantially decrease medical expenditures associated with the management of low-back pain.

Serious Adverse Events and Spinal Manipulative Therapy of the Low Back Region: A Systematic Review of Cases.

OBJECTIVE: The purpose of this study was to systematically search the literature for studies reporting serious adverse events following lumbopelvic spinal manipulative therapy (SMT) and to describe the case details. METHODS: A systematic search was conducted in PubMed including MEDLINE, EMBASE, CINAHL, and The Cochrane Library up to January 12, 2012, by an experienced reference librarian. Study selection was performed by 2 independent reviewers using predefined criteria. We included cases involving individuals 18 years or older who experienced a serious adverse event following SMT applied to the lumbar spine or pelvis by any type of provider (eg, chiropractic, medical, physical therapy, osteopathic, layperson). A serious adverse event was defined as an untoward occurrence that results in death or is life threatening, requires hospital admission, or results in significant or permanent disability. We included studies published in English, German, Dutch, and Swedish. RESULTS: A total of 2046 studies were screened, and 41 studies reporting on 77 cases were included. Important case details were frequently unreported, such as descriptions of SMT technique, the pre-SMT presentation of the patient, the specific details of the adverse event, time from SMT to the adverse event, factors contributing to the adverse event, and clinical outcome. Adverse events consisted of cauda equina syndrome (29 cases, 38% of total); lumbar disk herniation (23 cases, 30%); fracture (7 cases, 9%); hematoma or hemorrhagic cyst (6 cases, 8%); or other serious adverse events (12 cases, 16%) such as neurologic or vascular compromise, soft tissue trauma, muscle abscess formation, disrupted fracture healing, and esophageal rupture. CONCLUSIONS: This systematic review describes case details from published articles that describe serious adverse events that have been reported to occur following SMT of the lumbopelvic region. The anecdotal nature of these cases does not allow for causal inferences between SMT and the events identified in this review. Recommendations regarding future case reporting and research aimed at furthering the understanding of the safety profile of SMT are discussed.
