Frequency and indication of non-musculoskeletal examinations: a cross-sectional survey of Quebec chiropractors

BACKGROUND

Approximately 1% of low back pain is estimated to be caused by serious systemic diseases, including cancer, infection, or abdominal aortic dissection. This study aimed to determine the frequency of execution of non-MSK physical examination procedures among Quebec chiropractors and to identify the clinical context that prompts them to use these physical examination procedures.

METHODS

Cross-sectional survey containing 44 questions administered to a random sample of Quebec chiropractors using a succession of online, postal and phone questionnaires. The 4-part survey questionnaire contained six demographic questions, 28 single-choice questions to determine the frequency of execution of non-MSK physical examination procedures, seven short clinical vignettes for which the respondents had to select the non-MSK examinations that would be required, and two questions inquiring about the proportion of new patients for which participants' felt non-MSK examinations were necessary and whether appropriate assessments were performed. The questionnaire was pilot tested, and feedback received integrated prior to administration. We conducted descriptive statistics, Pearson correlations, and an ANOVA.

RESULTS

The survey was completed by 182 chiropractors (response rate: 36.4%). The most commonly non-musculoskeletal examination performed daily were blood pressure (12.1%) and cranial nerves (4.9%). The most common tests never performed were oxygen saturation (68.7%), cardiac auscultation (69.2%), tibio-brachial index (71.4%), breast (86.8%), rectal (96.7%), testicular (95.6%), and vaginal (99.9%) exams. Female chiropractors and Quebec University in Trois-Rivières graduates reported that a significantly higher proportion of their new patients required a non-musculoskeletal physical examination compared to male participants (37.2% vs 28.3%) or Canadian Memorial Chiropractic College graduates (33.9% vs 19.9%). Reason for not performing a physical examination included the belief that another healthcare professional was better positioned to perform and/or interpret the related tests (76.4%).

CONCLUSIONS

Vital signs and cranial nerve examinations were the most frequency performed non-musculoskeletal examinations reported by chiropractors. Apart from the genitourinary exam almost never performed, most participants chose non-musculoskeletal examinations deemed appropriate for the patient's presentation.

Establishing the prognostic profile of patients with work-related musculoskeletal disorders: Development and acceptability of the MAPS questionnaire

PURPOSE

Work-related musculoskeletal disorders (WRMD) are the most common causes of disability worldwide and are associated with significant use of healthcare. One way to optimize the clinical outcomes of injured workers receiving rehabilitation is to identify and address individual prognostic factors (PF), which can facilitate the personalization of the treatment plan. As there is no pragmatic and systematic method to collect prognostic-related data, the purpose of the study was to develop and assess the acceptability of a set of questionnaires to establish the "prognostic profile" of workers with WRMD.

METHODS

We utilized a multistep process to inform the acceptability of the Measures Associated to PrognoStic (MAPS) questionnaire. During STEP-1, a preliminary version of the was developed through a literature search followed by an expert consensus including a patient-advisor. During STEP-2, future users (rehabilitation professionals, healthcare administrators and compensation officers) were consulted through an online survey and were asked to rate the relevance of each content item; items that obtained ≥80% of "totally agree" answers were included. They were also asked to prioritize PF according to their usefulness for clinical decision-making, as well as perceived efficacy to enhance the treatment plan.

RESULTS

The questionnaire was developed with three categories: the outcome predicted, the unique PF, and prognostic tools. Personal PF (i.e.: coping strategies, fear-avoidance beliefs), pain related PF (i.e.: pain intensity/severity, duration of pain), and work-related PF (i.e.: work physical demands, work accommodations) were identified to be totally relevant and included in the questionnaire. 84% of the respondents agreed that their patients could complete the MAPS questionnaire in their clinical setting, while 75% totally agreed that the questionnaire is useful to personalize rehabilitation interventions.

CONCLUSION

The MAPS questionnaire was deemed acceptable to establish the "prognostic profile" of injured workers and help the clinicians in the treatment decision-making process.

Chiropractic care and research priorities for the pediatric population: a cross-sectional survey of Quebec chiropractors

BACKGROUND

Chiropractors commonly treat pediatric patients within their private practices. The objectives of this study were (1) to identify the treatment techniques and health advice used by Quebec chiropractors with pediatric patients; (2) to explore the research priorities of Quebec chiropractors for the pediatric population; and (3) to identify Quebec chiropractors' training in the field of pediatric chiropractics.

METHODS

A web-based cross-sectional survey was conducted among all licensed Quebec chiropractors (Qc, Canada). Descriptive statistics were used to analyze all quantitative variables.

RESULTS

The results showed that among the 245 respondents (22.8% response rate), practitioners adapted their treatment techniques based on their patients' age group, thus using softer techniques with younger pediatric patients and slowly gravitating toward techniques used with adults when patients reached the age of six. In terms of continuing education, chiropractors reported an average of 7.87 h of training on the subject per year, which mostly came from either Quebec's College of Chiropractors (OCQ) (54.7%), written articles (46.9%) or seminars and conferences (43.7%). Both musculoskeletal (MSK) and viscerosomatic conditions were identified as high research priorities by the clinicians.

CONCLUSIONS

Quebec chiropractors adapt their treatment techniques to pediatric patients. In light of limited sources of continuing education in the field of pediatric chiropractics, practitioners mostly rely on the training provided by their provincial college and scientific publications. According to practitioners, future research priorities for pediatric care should focus on both MSK conditions and non-MSK conditions.

Understanding patient preferences for student clinician attire: a cross-sectional study of a student chiropractic clinic in Australia

Objectives

Previous studies have investigated the role of clinical attire in establishing patient-held perceptions of professionalism and knowledgeability across various healthcare settings. This study aimed to understand patients' preferences for chiropractic student attire.

Methods

Three hundred and twenty patients were recruited from a university chiropractic clinic and asked to complete an online questionnaire. The patients' preferences for five different attires were rated and calculated as the composite score of five domains (knowledgeable, trustworthy, caring, professional, and comfortable).

Results

While 71.9% of participants indicated that how students dress was important to them, most (63.4%) disagreed that wearing a white coat was essential for chiropractic student clinicians. The most preferred form of attire was the current clinic shirt.

Conclusion

The attire worn by chiropractic student clinicians at a single institution was found to be an influential attribute. Student chiropractic clinicians should dress professionally to make a good first impression. This study provided some guidance with the ongoing debate around students' dress code.

Prognostic factors specific to work-related musculoskeletal disorders: An overview of recent systematic reviews

PURPOSE

Work-related injuries affect a considerable number of people each year and represent a significant burden for society. To reduce this burden, optimizing rehabilitation care by integrating prognostic factors (PF) into the clinical decision-making process is a promising way to improve clinical outcomes. The aim of this study was to identify PF specific to work-related musculoskeletal disorders.

METHODS

We performed an overview of systematic reviews reporting on PF that had the following outcomes of interest: Return to work, pain, disability, functional status, or poor outcomes. Each extracted PF was categorized according to its level of evidence (grade A or B) and whether it was modifiable or not. The risk of bias of each study was assessed with the ROBIS tool.

RESULTS

We retrieved 757 citations from 3 databases. After removing 307 duplicates, 450 records were screened, and 20 studies were retained. We extracted a total of 20 PF with a Grade A recommendation, where 7 were deemed modifiable, 11 non-modifiable and 2 were index test. For example, return to work expectations, previous sick leave, delay in referral and pain intensity were found to be predictors of return-to-work outcomes. We also identified 17 PF with a Grade B recommendation, where 11 were deemed modifiable. For example, poor general health, negative recovery expectations, coping and fear-avoidance beliefs, pain severity, and particularly physical work were found to predict return to work outcomes.

CONCLUSION

We found numerous modifiable PFs that can help clinicians personalize their treatment plan beyond diagnostic-related information for work-related musculoskeletal disorders.

Injuries and Health Issues Occurring During Offshore Transoceanic Sailing: A Survey of Recreational Sailors and Cruisers

INTRODUCTION

Most of the literature on sailing injuries is centered on competitive sailing, often involving a single regatta. The aims of this study were to provide a description of the types of injuries and illnesses sustained during amateur offshore cruising events, estimate their incidence, and investigate potential risk factors for injuries.

METHODS

We conducted a cross-sectional survey of self-reported sailing-related injuries and health issues during 4 different events organized by the World Cruising Club between 2014 and 2015. Prior to departure, sailors received an injury or health issue report form to complete during their sailing event. Questionnaires were then collected at the end of each event. Bivariable (Student's t tests and χ² tests) and mutilvariable logistic regression were used to study the associations among injuries, health issues, and the characteristics of sailors or sailboats.

RESULTS

The incidence of injuries and health issues among the respondents was 1.08 and 1.01 per 10,000 nautical miles, respectively. Smaller boats (P<0.001) and crews with less experience with the current boat (P<0.001) were associated with reporting of more injuries. Most of the injuries were reported during favorable weather conditions. Health issues were more frequent on smaller boats and with women (P=0.008), who reported significantly more seasickness (P<0.001), anxiety (P=0.037), and skin rash/fungal infection (P=0.021).

CONCLUSIONS

Injuries and health issues are relatively common among amateur offshore recreational sailors, but severe injuries are rare. Smaller boats and having less experience in sailing with the current boat were associated with more injuries. Preventive strategies should include a sailing experience requirement on the boat being sailed for all crew members, increasing the minimum boat size requirement for sailing events, and mandatory first-aid training prior to a cruising event for all crew members.

Chiropractic pediatric patient management and interdisciplinary collaboration: a descriptive cross-sectional study of chiropractors in Quebec

BACKGROUND

Worldwide, many patients, including minors, seek chiropractic care. The purpose of this study was to investigate the practice characteristics of chiropractors who treat pediatric patients in Quebec, Canada.

METHODS

We conducted a web-based cross-sectional survey of all licensed chiropractors working in Quebec (Canada). Data were collected using an adapted questionnaire. Descriptive statistics were produced for all the variables collected.

RESULTS

Among our 245 participants (response rate: 21%), 63% were women, and half defined themselves as general musculoskeletal (MSK) health care practitioners. Nearly all participants reported seeing 0-5 new pediatric patients/week, and the most common pediatric age group was 6-12 years old (57%). Pediatric patients were most commonly referred by family members and "word of mouth". The respondents most frequently indicated that they strongly agreed with statements affirming their confidence in their own diagnostic capacities regarding MSK disorders with respect to all age groups as well as non-MSK disorders with regard to young teens. They reported a moderate level of agreement with similar statements concerning the diagnosis of non-MSK disorders in newborns, preschoolers, and children. Chiropractors rarely referred their pediatric patients to a nurse/family doctor or a pediatrician. When presented with potential pediatric red flags, the respondents commonly indicated that they would refer the patient to a physician in an emergency situation or for comanagement.

CONCLUSION

Chiropractors in Quebec are confident in their diagnoses of pediatric MSK conditions and refer patients to physicians in the rare event of a worrisome presentation. However, some chiropractors may have expectations that are unsupported by evidence regarding the diagnosis and management of non-MSK complaints.

Developing key performance indicators for the Canadian chiropractic profession: a modified Delphi study

Background

The purpose of this study is to develop a list of performance indicators to assess the status of the chiropractic profession in Canada.

Method

We conducted a 4-round modified Delphi technique (March 2018–January 2020) to reach consensus among experts and stakeholders on key status indicators for the chiropractic profession using online questionnaires. During the first round, experts suggested indicators for preidentified themes. Through the following two rounds, the importance and feasibility of each indicator was rated on an 11-point Likert scale, and their related potential sources of data identified. In the final round, provincial stakeholders were recruited to rate the importance of the indicators within the 90th percentile and identified those most important to their organisation.

Results

The first round generated 307 preliminary indicators of which 42 were selected for the remaining rounds, and eleven were preferentially selected by most of the provincial stakeholders. Experts agreed the feasibility of all indicators was high, and that data could be collected through a combination of data obtained from professional liability insurance records and survey(s) of the general population, patients, and chiropractors.

Conclusions

A set of performance indicators to assess the status of the Canadian chiropractic profession emerged from a scientific and stakeholder consensus.

Distinct care trajectories among persons living with arthritic conditions: A two-year state sequence analysis

OBJECTIVES

Developing solutions to optimize care trajectories (CareTs) requires examining patient journeys through the health care system. This study aimed to describe CareTs among people living with arthritis and evaluate their association with self-reported health outcomes.

METHODS

Analyses were conducted using the TorSaDE Cohort (n = 102,148), which connects the 2007 to 2016 Canadian Community Health Surveys (CCHS) with Quebec administrative databases (longitudinal claims). CareTs of participants living with arthritis according to CCHS (n = 16,631), over the two years before CCHS completion, were clustered using state sequence analysis (months as a time unit). CareT group membership was then put in association with self-reported outcomes (pain intensity and interference, self-perceived general and mental health).

RESULTS

The analysis revealed five CareT groups characterized predominantly by: (1) arthritis-related visits to a specialist (n = 2,756; 16.6%), (2) arthritis-related emergency department visits (n = 2,928; 17.6%), (3) very high all-cause health care utilization and arthritis-related hospitalizations (n = 1,570; 9.4%), (4) arthritis-related medical visits to general practitioners and specialists (n = 2,708; 16.3%), (5) low all-cause health care utilization (n = 6,669; 40.1%). Multivariable results revealed that CareT group membership was associated with higher levels of pain interference (CareT group #3 vs. #5: OR: 1.4, 95%CI: 1.1-1.8) and fair/poor self-perceived general health (CareT group #1 vs. #5: OR: 1.551, 95%CI: 1.319-1.824; #2 vs. #5: OR: 1.244, 95%CI: 1.062-1.457; #3 vs. #5: OR: 1.771, 95%CI: 1.451-2.162; #4 vs. #5: OR: 1.481, 95%CI: 1.265-1.735).

DISCUSSION

Sate sequence analysis is an innovative method of studying CareTs and valuable for making evidence-based decisions taking into account inter- and intra-individual variability.

Chiropractic techniques and treatment modalities included in academic programs: A survey of chiropractic educational institutions

OBJECTIVE

The chiropractic techniques that chiropractors learn during their training strongly influence the nature of treatments provided by chiropractors and their professional identity. The objective of this project is to provide an exhaustive description of all chiropractic techniques and treatment modalities taught in chiropractic educational institutions.

METHODS

International experts were solicited to provide feedback on the exhaustivity and clarity of our preliminary questionnaire. Following the expert suggestions, we administered our cross-sectional survey representatives of all chiropractic education institutions listed on the World Federation of Chiropractic website. We also asked the contact information for an additional contact from each institution and surveyed them for triangulation purposes.

RESULTS

Among the 47 chiropractic education institutions surveyed, 29 completed our survey (response rate: 62%) of which 18 (62%) had 2 respondents. Among all the chiropractic techniques and treatment modalities investigated, only the Diversified technique was included in the core curriculum of all responding institutions. A considerable proportion of the techniques or modalities studied were not included in the educational activities of the institutions, particularly within the manual tonal or reflex techniques, instrument-assisted articular techniques, as well as the other techniques or modalities categories. Surprisingly, exercise prescription was not included in the core curriculum of all the institutions. Some scientifically challenged approaches were included in the educational activities of more than 40% of the institutions.

CONCLUSION

The portfolio of therapeutic teaching varies greatly between chiropractic educational institutions. A more standardized therapeutic curriculum could be beneficial to reduce public and interprofessional confusion toward therapeutic approaches in chiropractic.

Student attitudes toward the International Clinical and Professional Chiropractic Education Position Statement and Evidence-based practice: a survey of UQTR chiropractic students

OBJECTIVE

The aim of this study is to describe the attitude of Université du Québec à Trois-Rivières (UQTR) chiropractic students toward the International Clinical and Professional Chiropractic Education Position Statement and evidence-based practice (EBP) beliefs.

METHODS

A cross-sectional survey was administered to all the UQTR chiropractic students. Using a five-point Likert scale, students were asked to rate their level of agreement with the position statement (10 items), EBP (2 items), interprofessional collaboration (2 items) and vitalistic philosophy (2 items).

RESULTS

Survey response rate was 71%. Students most frequently reported strong agreement with the position statement, EBP and interprofessional collaboration. They also most frequently disagreed with vitalistic philosophy. The attitude toward the position statement was positively correlated with the year of study in the program (r=0.10, p=0.019), EBP (r=0.56, p<0.001) and interprofessional collaboration (r=0.45, p <0.001).

CONCLUSIONS

UQTR chiropractic students demonstrate high levels of agreement with EBP and the Education Position Statement.

The global summit on the efficacy and effectiveness of spinal manipulative therapy for the prevention and treatment of non-musculoskeletal disorders: a systematic review of the literature

Background

A small proportion of chiropractors, osteopaths, and other manual medicine providers use spinal manipulative therapy (SMT) to manage non-musculoskeletal disorders. However, the efficacy and effectiveness of these interventions to prevent or treat non-musculoskeletal disorders remain controversial.

Objectives

We convened a Global Summit of international scientists to conduct a systematic review of the literature to determine the efficacy and effectiveness of SMT for the primary, secondary and tertiary prevention of non-musculoskeletal disorders.

Global summit

The Global Summit took place on September 14–15, 2019 in Toronto, Canada. It was attended by 50 researchers from 8 countries and 28 observers from 18 chiropractic organizations. At the summit, participants critically appraised the literature and synthesized the evidence.

Systematic review of the literature

We searched MEDLINE, Embase, the Cochrane Central Register of Controlled Trials, the Cumulative Index to Nursing and Allied Health, and the Index to Chiropractic Literature from inception to May 15, 2019 using subject headings specific to each database and free text words relevant to manipulation/manual therapy, effectiveness, prevention, treatment, and non-musculoskeletal disorders. Eligible for review were randomized controlled trials published in English. The methodological quality of eligible studies was assessed independently by reviewers using the Scottish Intercollegiate Guidelines Network (SIGN) criteria for randomized controlled trials. We synthesized the evidence from articles with high or acceptable methodological quality according to the Synthesis without Meta-Analysis (SWiM) Guideline. The final risk of bias and evidence tables were reviewed by researchers who attended the Global Summit and 75% (38/50) had to approve the content to reach consensus.

Results

We retrieved 4997 citations, removed 1123 duplicates and screened 3874 citations. Of those, the eligibility of 32 articles was evaluated at the Global Summit and 16 articles were included in our systematic review. Our synthesis included six randomized controlled trials with acceptable or high methodological quality (reported in seven articles). These trials investigated the efficacy or effectiveness of SMT for the management of infantile colic, childhood asthma, hypertension, primary dysmenorrhea, and migraine. None of the trials evaluated the effectiveness of SMT in preventing the occurrence of non-musculoskeletal disorders. Consensus was reached on the content of all risk of bias and evidence tables. All randomized controlled trials with high or acceptable quality found that SMT was not superior to sham interventions for the treatment of these non-musculoskeletal disorders. Six of 50 participants (12%) in the Global Summit did not approve the final report.

Conclusion

Our systematic review included six randomized clinical trials (534 participants) of acceptable or high quality investigating the efficacy or effectiveness of SMT for the treatment of non-musculoskeletal disorders. We found no evidence of an effect of SMT for the management of non-musculoskeletal disorders including infantile colic, childhood asthma, hypertension, primary dysmenorrhea, and migraine. This finding challenges the validity of the theory that treating spinal dysfunctions with SMT has a physiological effect on organs and their function. Governments, payers, regulators, educators, and clinicians should consider this evidence when developing policies about the use and reimbursement of SMT for non-musculoskeletal disorders.

Making Contributions and Defining Success: An eDelphi Study of the Inaugural Cohort of CIHR Health System Impact Fellows, Host Supervisors and Academic Supervisors

Context:

The Health System Impact (HSI) Fellowship, an innovative training program developed by the Canadian Institutes of Health Research's Institute of Health Services and Policy Research, provides PhD-trained health researchers with an embedded, experiential learning opportunity within a health system organization.

Methods/Design:

An electronic Delphi (eDelphi) study was conducted to: (1) identify the criteria used to define success in the program and (2) elucidate the main contributions fellows made to their organizations. Through an iterative, two-round eDelphi process, perspectives were elicited from three stakeholder groups in the inaugural cohort of the HSI Fellowship: HSI fellows, host supervisors and academic supervisors.

Discussion:

A consensus was reached on many criteria of success for an embedded research fellowship and on several perceived contributions of the fellows to their host organization and academic institutions. This work begins to identify specific criteria for success in the fellowship that can be used to improve future iterations of the program.

A framework for value-creating learning health systems

Background

Interest in value-based healthcare, generally defined as providing better care at lower cost, has grown worldwide, and learning health systems (LHSs) have been proposed as a key strategy for improving value in healthcare. LHSs are emerging around the world and aim to leverage advancements in science, technology and practice to improve health system performance at lower cost. However, there remains much uncertainty around the implementation of LHSs and the distinctive features of these systems. This paper presents a conceptual framework that has been developed in Canada to support the implementation of value-creating LHSs.

Methods

The framework was developed by an interdisciplinary team at the Institut national d’excellence en santé et en services sociaux (INESSS). It was informed by a scoping review of the scientific and grey literature on LHSs, regular team discussions over a 14-month period, and consultations with Canadian and international experts.

Results

The framework describes four elements that characterise LHSs, namely (1) core values, (2) pillars and accelerators, (3) processes and (4) outcomes. LHSs embody certain core values, including an emphasis on participatory leadership, inclusiveness, scientific rigour and person-centredness. In addition, values such as equity and solidarity should also guide LHSs and are particularly relevant in countries like Canada. LHS pillars are the infrastructure and resources supporting the LHS, whereas accelerators are those specific structures that enable more rapid learning and improvement. For LHSs to create value, such infrastructures must not only exist within the ecosystem but also be connected and aligned with the LHSs’ strategic goals. These pillars support the execution, routinisation and acceleration of learning cycles, which are the fundamental processes of LHSs. The main outcome sought by executing learning cycles is the creation of value, which we define as the striking of a more optimal balance of impacts on patient and provider experience, population health and health system costs.

Conclusions

Our framework illustrates how the distinctive structures, processes and outcomes of LHSs tie together with the aim of optimising health system performance and delivering greater value in health systems.

Which Characteristics are Associated with the Timing of the First Healthcare Consultation, and Does the Time to Care Influence the Duration of Compensation for Occupational Back Pain?

Purpose To identify the characteristics associated with the timing of the first healthcare consultation and to measure the impact of that timing on the duration of the first episode of compensation for occupational back pain following the injury. Methods We analyzed data from a cohort of workers with compensated back pain in 2005 in Ontario obtained from the Workplace Safety and Insurance Board. Cox multivariable survival models were performed to identify factors associated with the time to care and to measure its association with the length of the first episode of 100 % compensation. Results Among the 5520 claims analyzed, 93.7 % of workers accessed care within the first week (average = 2.1 days; median = 1 day). Time to care was shorter for males, for workers who had received previous compensation and for those with access to an early return to work program. Age, number of employees in the company and personal earnings were positively associated with the time to care. More severe nature of injury, employers doubt about the work-relatedness of the injury and consulting a physiotherapist as the first healthcare provider were also associated with longer time to care. Considering potential confounders, longer time to care was significantly associated with a delay in the end of the first episode of compensation (hazard ratio = 0.98; P < 0.001). Conclusion Temporal access to a source of care is not problematic for the vast majority of Ontarian workers who receive compensation for occupational back pain; however, for the minority of workers who do not rapidly access care, the timing of the first healthcare consultation is a significant predictor of the duration of the first episode of compensation.

Association Between the Type of First Healthcare Provider and the Duration of Financial Compensation for Occupational Back Pain

Objective To compare the duration of financial compensation and the occurrence of a second episode of compensation of workers with occupational back pain who first sought three types of healthcare providers. Methods We analyzed data from a cohort of 5511 workers who received compensation from the Workplace Safety and Insurance Board for back pain in 2005. Multivariable Cox models controlling for relevant covariables were performed to compare the duration of financial compensation for the patients of each of the three types of first healthcare providers. Logistic regression was used to compare the occurrence of a second episode of compensation over the 2-year follow-up period. Results Compared with the workers who first saw a physician (reference), those who first saw a chiropractor experienced shorter first episodes of 100 % wage compensation (adjusted hazard ratio [HR] = 1.20 [1.10-1.31], P value < 0.001), and the workers who first saw a physiotherapist experienced a longer episode of 100 % compensation (adjusted HR = 0.84 [0.71-0.98], P value = 0.028) during the first 149 days of compensation. The odds of having a second episode of financial compensation were higher among the workers who first consulted a physiotherapist (OR = 1.49 [1.02-2.19], P value = 0.040) rather than a physician (reference). Conclusion The type of healthcare provider first visited for back pain is a determinant of the duration of financial compensation during the first 5 months. Chiropractic patients experience the shortest duration of compensation, and physiotherapy patients experience the longest. These differences raise concerns regarding the use of physiotherapists as gatekeepers for the worker's compensation system. Further investigation is required to understand the between-provider differences.

Workers' characteristics associated with the type of healthcare provider first seen for occupational back pain

BACKGROUND

Few studies have compared the factors that drive patients' decision to choose a chiropractor, physician or physiotherapist as their first healthcare provider for occupational back pain. The purpose of this study is to identify characteristics associated with the choice of first healthcare provider seen for acute uncomplicated occupational back pain.

METHODS

We analyzed data collected by the Workplace Safety and Insurance Board from a cohort of workers with compensated back pain in 2005 in Ontario (Canada). Multivariable logistic regression models were created to identify factors associated with the type of first healthcare provider seen (chiropractor, physician, or physiotherapist). Adjustments to the final models were evaluated using the area under the receiver-operating characteristics curve (ROC).

RESULTS

According to the 5520 analyzed claims, 85.3 % of the patients saw a physician, 11.4 % saw a chiropractor, and 3.2 % saw a physiotherapist. Longer job tenure (odds ratio (OR) = 1.02, P = 0.004), higher gross personal income (OR = 1.06, P = 0.018), mixed-manual job (OR = 1.35, P = 0.004) and previous similar injury (OR = 1.60, P < 0.001) increased the odds of seeing a chiropractor rather than a physician, while the size of the community (>500,000 inhabitants) and the availability of an early return to work program in the workplace (OR = 0.77, P = 0.035) decreased it. The odds of seeing a physiotherapist rather than a physician increased with increasing age (OR = 1.19, P = 0.019), previous similar injury (OR = 1.71, P < 0.001) and severity of injury (OR = 2.03, P = 0.010). Increased age (OR = 1.28, P = 0.008) and size of community (>1,500,000 inhabitants; OR = 2.58, P = 0.002) increased the odds of seeing a physiotherapist rather than a chiropractor, while holding a mixed-manual job significantly decreased those odds (OR = 0.63, P = 0.044). The area under the ROC curve of our multivariable models varied from 0.62 to 0.64.

CONCLUSION

The type of first healthcare provider sought for occupational back pain is influenced by injury-and work-related factors and by the worker's age, income and community size. Contrary to previous studies, the workers who first sought a physician did not have higher odds of having a severe injury.

Effectiveness and Economic Evaluation of Chiropractic Care for the Treatment of Low Back Pain: A Systematic Review of Pragmatic Studies

Background Context

Low back pain (LBP) is one of the leading causes of disability worldwide and among the most common reasons for seeking primary sector care. Chiropractors, physical therapists and general practitioners are among those providers that treat LBP patients, but there is only limited evidence regarding the effectiveness and economic evaluation of care offered by these provider groups.

Purpose

To estimate the clinical effectiveness and to systematically review the literature of full economic evaluation of chiropractic care compared to other commonly used care approaches among adult patients with non-specific LBP.

Study Design

Systematic reviews of interventions and economic evaluations.

Methods

A comprehensive search strategy was conducted to identify 1) pragmatic randomized controlled trials (RCTs) and/or 2) full economic evaluations of chiropractic care for low back pain compared to standard care delivered by other healthcare providers. Studies published between 1990 and 4^th June 2015 were considered. Primary outcomes included pain, functional status and global improvement. Study selection, critical quality appraisal and data extraction were conducted by two independent reviewers. Data from RCTs with low risk of bias were included in a meta-analysis to determine effect estimates. Cost estimates of full economic evaluations were converted to 2015 USD and results summarized using Slavin’s qualitative best-evidence synthesis.

Results

Six RCTs and three full economic evaluations were scientifically admissible. Five RCTs with low risk of bias compared chiropractic care to exercise therapy (n = 1), physical therapy (n = 3) and medical care (n = 1). Overall, we found similar effects for chiropractic care and the other types of care and no reports of serious adverse events. Three low to high quality full economic evaluations studies (one cost-effectiveness, one cost-minimization and one cost-benefit) compared chiropractic to medical care. Given the divergent conclusions (favours chiropractic, favours medical care, equivalent options), mixed-evidence was found for economic evaluations of chiropractic care compared to medical care.

Conclusion

Moderate evidence suggests that chiropractic care for LBP appears to be equally effective as physical therapy. Limited evidence suggests the same conclusion when chiropractic care is compared to exercise therapy and medical care although no firm conclusion can be reached at this time. No serious adverse events were reported for any type of care. Our review was also unable to clarify whether chiropractic or medical care is more cost-effective. Given the limited available evidence, the decision to seek or to refer patients for chiropractic care should be based on patient preference and values. Future studies are likely to have an important impact on our estimates as these were based on only a few admissible studies.

Chiropractors' characteristics associated with their number of workers' compensation patients

STUDY DESIGN

A cross-sectional survey.

OBJECTIVE

The purpose of this study was to identify characteristics of Canadian doctors of chiropractic (DCs) associated with their number of workers' compensation patients.

SUMMARY OF BACKGROUND DATA

It has been previously hypothesized that DCs that treat a relatively high volume of workers' compensation cases may have different characteristics than the general chiropractic community.

METHODS

Secondary data analyses were performed on data collected in the 2011 survey of the Canadian Chiropractic Resources Databank (CCRD). The CCRD survey included 81 questions concerning the practice and concerns of DCs. Of the 6,533 mailed questionnaires, 2,529 (38.7%) were returned. Of these, 652 respondents did not meet our inclusion criteria, and our final study sample included 1,877 respondents. Bivariate analyses were conducted between predetermined independent variables and the annual number of workers' compensation patients. A negative binomial multivariate regression was performed to identify significant factors associated with the number of workers' compensation patients.

RESULTS

On average, DCs received 10.3 (standard deviation (SD) = 17.6) workers' compensation cases and nearly one-third did not receive any such cases. The type of clinic (other than sole provider), practice area population (smaller than 500,000), practice province (other than Quebec), number of practice hours per week, number of treatments per week, main sector of activity (occupational/ industrial), care provided to patients (electrotherapy, soft-tissue therapy), percentage of patients with neuromusculoskeletal conditions, and percentage of patients referred by their employer or a physician were associated with a higher annual number of workers' compensation cases.

CONCLUSION

Canadian DCs who reported a higher volume of workers' compensation patients had practices oriented towards the treatment of injured workers, collaborated with other health care providers, and facilitated workers' access to care.

Conservative treatment of a rock climber with a SLAP lesion: a case report

This case report describes the clinical presentation and conservative treatment of a patient who suffered from a superior labrum anteroposterior (SLAP) tear of the shoulder after a rock climbing session. The 26 year old man had injured his right shoulder while trying to reach a distant socket with his shoulder 90° abducted and in extreme external rotation. After initial treatment failure in chiropractic, the patient sought an orthopaedist and physiotherapy care. A contrast magnetic resonance examination revealed a SLAP lesion. Awaiting orthopaedic consultation and in the absence of clinical improvement the patient sought care from a second chiropractor. Clinical examination revealed a mild winging of the right scapula and the presence of trigger points in the rotator cuff muscles, biceps, rhomboids and serratus anterior. The chiropractic treatment then included soft tissue mobilization and the prescription of strengthening exercises of the serratus anterior and rotator cuff muscles. After 4 sessions, the patient did not feel any pain and gradually resumed all his recreational activities. Clinicians should be aware that SLAP lesions are difficult to identify clinically and that manual therapy might be an important component of conservative treatment of SLAP lesions.

Effectiveness and economic evaluation of chiropractic care for the treatment of low back pain: a systematic review protocol

BACKGROUND

Chiropractic care is a common treatment for low back pain (LBP). Previous studies have failed to clarify the relative cost-effectiveness of chiropractic care in comparison with other commonly used approaches because previous attempts to synthetize the economic literature has only included partial economic evaluations. The objective of this project is to estimate the clinical effectiveness and cost-effectiveness of chiropractic care compared to other commonly used care approaches among adult patients with non-specific LBP.

METHODS/DESIGN

Two systematic reviews will be conducted to identify 1) randomized controlled trials and 2) full economic evaluations of chiropractic care for low back pain compared to standard care provided by other healthcare providers. We will conduct searches in specialized electronic databases for randomized controlled trials and full economic evaluations published between 1990 and 2014 using a combination of keywords and MeSH terms. This will be supplemented by a search of the gray literature. Citations, abstracts, and relevant papers will be screened for eligibility by two reviewers independently. Studies will be critically appraised using 1) the Cochrane risk of bias tool and 2) the Drummond (BMJ) checklist. Results will be summarized using Slavin's qualitative best-evidence synthesis approach. Data relating to the primary outcomes of the effectiveness study will be evaluated for inclusion in meta-analyses. The costs will be standardized to the same currency (USD) and adjusted to the same year for inflation. The incremental cost-effectiveness, incremental net benefit, and relevant confidant intervals will be recalculated in order to facilitate comparison between studies.

DISCUSSION

Our review will evaluate both the clinical effectiveness and the cost-effectiveness associated with chiropractic care for LBP. A more precise estimate of the cost-effectiveness of chiropractic care for LBP relative to other forms of conservative care is needed for decision-makers and third-party payers to offer best care options for LBP. Our results will facilitate evidence-based management of patients with LBP and identify key areas for future research.

Beyond the spine: a new clinical research priority

Over the past two decades, clinical research within the chiropractic profession has focused on the spine and spinal conditions, specifically neck and low back pain. However, there is now a small group of chiropractors with clinical research training that are shifting their focus away from traditional research pursuits towards new and innovative areas. Specifically, these researchers are now delving into areas such as brain injury, work disability prevention, undifferentiated chest pain, hip osteoarthritis, and prevention of pain in children and adolescents to name a few. In this paper, we highlight recent research in these new areas and discuss how clinical research efforts in musculoskeletal areas beyond the spine can benefit patient care and the future of the chiropractic profession.

Fracture of the lateral tubercle of the posterior talar process caused by a rock-climbing fall: a case report

The purpose of this case report is to describe the clinical presentation of a patient who suffered from a fracture of the lateral tubercle of the posterior talar process caused by a fall while rock-climbing. The initial evaluation revealed diffuse ankle swelling, tenderness, and pain at the distal aspect of both malleoli. Plain film radiography revealed a fracture of the posterior process of the talus. Computed tomography (CT) outlined the extension of the fracture line in the postero-lateral aspect of the body of the talus with minimal displacement. The patient was treated conservatively with an Aircast© walking boot for 6 weeks (non-weight-bearing) followed by a 2-week period of partial weight bearing. At the 8 week follow-up, he reported minimal tenderness and normal ankle function. Clinicians should be aware that talar fracture identification on plain films is difficult and computed tomography or magnetic resonance imaging may be required.

Subtle radiographic presentation of a pleural effusion secondary to a cancer of unknown primary: a case study

Carcinoma of unknown primary sites is a clinical syndrome that represents many types of cancer. The mortality rate associate to this type of cancer is elevated and a rapid medical referral is required for patients presenting this condition. Pleural effusion may be the only visible sign. We report a case of pleural effusion secondary to a cancer of unknown primary site in a 60-year-old man that sought chiropractic care for radiating low back pain. The radiographic studies revealed a pleural effusion as one of the only significant finding. This article will address the clinical presentation, radiographic studies and a discussion on the radiographic detection of pleural effusion.

Impairment assessment of lateral epicondylitis through electromyography and dynamometry

OBJECTIVES

To investigate changes in muscular activity and strength of subjects diagnosed with lateral epicondylitis (LE). To assess the appropriateness of these measures in the patient's follow-up.

METHODS

Twenty-four subjects (11 men and 13 women) with LE, were evaluated at baseline and after 5 weeks of an experimental treatment. Measurements included: the (1) pain-free grip (PFG), (2) maximal isometric strength, (3) surface electromyography (EMG) of forearm muscle (healthy and affected), (4) a visual analogue scale (VAS), and (5) the Patient Rated Tennis Elbow Evaluation (PRTEE) (Canadian-French version).

RESULTS

All subjects showed improvement in VAS and PRTEE. The maximal isometric strength during flexion and extension of the wrist and the EMG analysis failed to discriminate the affected from the healthy elbow during the initial assessment. Only the PFG measured with the elbow in extension could discriminate elbows with LE from the healthy ones.

CONCLUSIONS

The use of the PFG with the elbow in extension seems to be the most indicated strength measurement to monitor the recovery of patients with LE. The EMG acquisition protocol used in this research was not adequate to monitor effectively the recovery of LE.

Cross-cultural adaptation of the patient-rated tennis elbow evaluation to Canadian French

INTRODUCTION

No questionnaire is available to evaluate disability levels in French-speaking patients suffering from tennis elbow.

PURPOSE OF THE STUDY

To perform a cross-cultural adaptation of the English version of the Patient-rated Tennis Elbow Evaluation (PRTEE) into Canadian French.

METHODS

The PRTEE was cross-culturally adapted to Canadian French according to well-established guidelines. Thirty-two patients with tennis elbow completed the prefinal version of the PRTEE. The construct validity, longitudinal validity, and responsiveness were assessed through comparisons with the Visual Analog Scale (VAS) measuring pain and the pain-free grip (PFG) at baseline, six weeks and three months. The internal consistency was assessed by Cronbach's alpha and the item-total correlations.

RESULTS

The adaptation process resolved the discrepancy between the forward and back translation. The scores of PRTEE were adequately distributed without floor or ceiling effect. Item completion was good. The correlation between the PRTEE and the VAS was moderate to high (r=0.64-0.77) and statistically significant. There was also a low but significant correlation between the PRTEE and PFG (r=-0.38 to -0.48). For the longitudinal construct validity, the correlation with the VAS was moderate to high and statistically significant (r=0.68 and 0.88, p<0.01). The effect size (0.8; 1.0) and the standardized response mean (0.9; 1.0) were high and at least as good as the other outcomes. Internal consistency of the total score was high (Cronbach alpha=0.93) and item-total correlations were substantial for all items (0.58-0.85).

CONCLUSIONS

This study supports linguistic and conceptual equivalence of our Canadian French version. Because this version of the PRTEE demonstrated good acceptability, construct validity, internal consistency, and responsiveness, it may be used in both research and clinical setting.
