Self-reported hard physical work combined with heavy smoking or overweight may result in so-called Modic changes

<p>Abstract</p> <p>Background</p> <p>Recently, the MRI finding of "Modic changes" has been identified as pathologic spinal condition that probably reflects a vertebral inflammatory process (VIP), which coincides with spinal pain in most. We hypothesized that heavy smoking in combination with macro- or repeated microtrauma could lead to VIP. The objectives were to investigate if combinations of self-reported heavy smoking, hard physical work, and overweight would be more strongly linked with VIP than with other spinal conditions, such as degenerated discs and non-specific low back pain (LBP).</p> <p>Methods</p> <p>Secondary analysis was made of a data base pertaining to a population-based cross-sectional study. A population-generated cohort of 412 40-yr old Danes provided questionnaire information on smoking, weight, height, type of work, and LBP. MRI was used to determine the presence/absence of disc degeneration and of VIP. Associations were tested between three explanatory variables (type of work, smoking, and body mass index) and four outcome variables (LBP in the past year, more persistent LBP in the past year, disc degeneration, and VIP). Associations with these four outcome variables were studied for each single explanatory variable and for combinations of two at a time, and, finally, in a multivariable analysis including all three explanatory variables.</p> <p>Results</p> <p>There were no significant associations between the single explanatory variables and the two pain variables or with disc degeneration. However, VIP was found in 15% of non-smokers vs. 26% of heavy smokers. Similarly, VIP was noted in 11% of those in sedentary jobs vs. 31% of those with hard physical work. Further, the prevalence of VIP in those, who neither smoked heavily nor had a hard physical job was 13%, 25% in those who either smoked heavily or had a hard physical job, and 41% in those who both smoked heavily and worked hard. The odds ratio was 4.9 (1.6–13.0) for those who were both heavy smokers and had a hard physical job as compared to those who were classified as "neither". Similar but weaker findings were noted for the combination of overweight and hard physical work but not for the combination of smoking and overweight.</p> <p>Conclusion</p> <p>Hard physical work in combination with either heavy smoking or overweight is strongly associated with VIP. If this finding can be reproduced in other studies, it may have consequences in relation to both primary and secondary prevention of LBP, because blue collar workers, who are most likely to experience the consequences of LBP, also are those who are most likely to smoke.</p

The Nordic maintenance care program:case management of chiropractic patients with low back pain--defining the patients suitable for various management strategies

<p>Abstract</p> <p>Background</p> <p>Maintenance care is a well known concept among chiropractors, although there is little knowledge about its exact definition, its indications and usefulness. As an initial step in a research program on this phenomenon, it was necessary to identify chiropractors' rationale for their use of maintenance care. Previous studies have identified chiropractors' choices of case management strategies in response to different case scenarios. However, the rationale for these management strategies is not known. In other words, when presented with both the case, and different management strategies, there was consensus on how to match these, but if only the management strategies were provided, would chiropractors be able to define the cases to fit these strategies? The objective with this study was to investigate if there is a common pattern in Finnish chiropractors' case management of patients with low back pain (LBP), with special emphasis on long-term treatment.</p> <p>Methods</p> <p>Information was obtained in a structured workshop. Fifteen chiropractors, members of the Finnish Chiropractors' Union, and present at the general assembly, participated throughout the entire workshop session. These were divided into five teams each consisting of 3 people. A basic case of a patient with low back pain was presented together with six different management strategies undertaken after one month of treatment. Each team was then asked to describe one (or several) suitable case(s) for each of the six strategies, based on the aspects of 1) symptoms/findings, 2) the low back pain history in the past year, and 3) other observations. After each session the people in the groups were changed. Responses were collected as key words on flip-over boards. These responses were grouped and counted.</p> <p>Results</p> <p>There appeared to be consensus among the participants in relation to the rationale for at least four of the management strategies and partial consensus on the rationale for the remaining two. In relation to maintenance care, the patient's past history was important but also the doctor-patient relationship.</p> <p>Conclusion</p> <p>These results confirm that there is a pattern among Nordic chiropractors in how they manage patients with LBP. More information is needed to define the "cut-point" for the indication of prolonged care.</p

Maintenance care in chiropractic – what do we know?

<p>Abstract</p> <p>Background</p> <p>Back problems are often recurring or chronic. It is therefore not surprising that chiropractors wish to prevent their return or reduce their impact. This is often attempted with a long-term treatment strategy, commonly called maintenance care. However, some aspects of maintenance care are considered controversial. It is therefore relevant to investigate the scientific evidence forming the basis for its use.</p> <p>Objectives</p> <p>A review of the literature was performed in order to obtain answers to the following questions: What is the exact definition of maintenance care, what are its indications for use, and how is it practised? How common is it that chiropractors support the concept of maintenance care, and how well accepted is it by patients? How frequently is maintenance care used, and what factors are associated with its use? Is maintenance care a clinically valid method of approach, and is it cost-effective for the patient?</p> <p>Results</p> <p>Thirteen original studies were found, in which maintenance care was investigated. The relative paucity of studies, the obvious bias in many of these, the lack of exhaustive information, and the diversity of findings made it impossible to answer any of the questions.</p> <p>Conclusion</p> <p>There is no evidence-based definition of maintenance care and the indications for and nature of its use remains to be clearly stated. It is likely that many chiropractors believe in the usefulness of maintenance care but it seems to be less well accepted by their patients. The prevalence with which maintenance care is used has not been established. Efficacy and cost-effectiveness of maintenance care for various types of conditions are unknown. Therefore, our conclusion is identical to that of a similar review published in 1996, namely that maintenance care is not well researched and that it needs to be investigated from several angles before the method is subjected to a multi-centre trial.</p

The Nordic Maintenance Care Program – An interview study on the use of maintenance care in a selected group of Danish chiropractors

<p>Abstract</p> <p>Background</p> <p>Although maintenance care appears to be relatively commonly used among chiropractors, the indications for its use are incompletely understood. A questionnaire survey was recently carried out among Swedish chiropractors in order to identify their choice of various management strategies, including maintenance care. That study revealed a common pattern of choice of strategies. However, it would be necessary to verify these findings in another study population and to obtain some additional information best collected through an interview.</p> <p>Objectives</p> <p>The main aim of the present study was to attempt to reproduce the findings in the Swedish study and to obtain more information on the use of maintenance care.</p> <p>Method</p> <p>A group of 11 chiropractors were selected because they used maintenance care. They were interviewed using the questionnaire from the previous Swedish survey. The questionnaire consisted of a simple description of a hypothetical patient with low back pain and nine possible ways in which the case could develop ("scenarios"). They could choose between six different management strategies for each scenario. In addition, the chiropractors were encouraged to provide their own definition of maintenance care in an open-ended question. Interviews were taped, transcribed and analyzed. For the open-ended question, statements were identified relating to six pre hoc defined topics on the inclusion criteria/rationale for maintenance care, the frequency of treatments, and the duration of the maintenance care program.</p> <p>Results</p> <p>The open-ended question revealed that in patients with low back pain, maintenance care appears to be offered to prevent new events. The rationale was to obtain optimal spinal function. There appears to be no common convention on the frequency of treatments and duration of the treatment program was not mentioned by any of the interviewees.</p> <p>Conclusion</p> <p>The results from the questionnaire in the Danish survey showed that the response pattern for the nine scenarios was similar to that obtained in the Swedish survey. There seems to be relative agreement between chiropractors working in different countries and sampled through different methods in relation to their choice of management strategies in patients with low back pain. However, more precise information is needed on the indications for maintenance care and its treatment program, before proceeding to studying its clinical validity.</p

The Nordic back pain subpopulation program: predicting outcome among chiropractic patients in Finland

<p>Abstract</p> <p>Background</p> <p>In a previous Swedish study it was shown that it is possible to predict which chiropractic patients with persistent LBP will not report definite improvement early in the course of treatment, namely those with LBP for altogether at least 30 days in the past year, who had leg pain, and who did not report definite general improvement by the second treatment. The objectives of this study were to investigate if the predictive value of this set of variables could be reproduced among chiropractic patients in Finland, and if the model could be improved by adding some new potential predictor variables.</p> <p>Methods</p> <p>The study was a multi-centre prospective outcome study with internal control groups, carried out in private chiropractic practices in Finland. Chiropractors collected data at the 1st, 2^ndand 4^thvisits using standardized questionnaires on new patients with LBP and/or radiating leg pain. Status at base-line was identified in relation to pain and disability, at the 2^ndvisit in relation to disability, and "definitely better" at the 4^thvisit in relation to a global assessment. The Swedish questionnaire was used including three new questions on general health, pain in other parts of the spine, and body mass index.</p> <p>Results</p> <p>The Swedish model was reproduced in this study sample. An alternative model including leg pain (yes/no), improvement at 2^ndvisit (yes/no) and BMI (underweight/normal/overweight or obese) was also identified with similar predictive values. Common throughout the testing of various models was that improvement at the 2^ndvisit had an odds ratio of approximately 5. Additional analyses revealed a dose-response in that 84% of those patients who fulfilled none of these (bad) criteria were classified as "definitely better" at the 4^thvisit, vs. 75%, 60% and 34% of those who fulfilled 1, 2 or all 3 of the criteria, respectively.</p> <p>Conclusion</p> <p>When treating patients with LBP, at the first visits, the treatment strategy should be different for overweight/obese patients with leg pain as it should be for all patients who fail to improve by the 2^ndvisit. The number of predictors is also important.</p

How comprehensively is evidence-based practice represented in councils on chiropractic education (CCE) educational standards: A systematic audit

Background The incorporation of evidence-based practice (EBP) is widely recognised as a necessary process for entry-level health professional training. Accreditation documents reflect the practice standards of health professions. No previous study has assessed the extent to which EBP has been taken up by chiropractic regulatory/licencing authorities, known as Councils on Chiropractic Education (CCEs), around the world. The purposes of this study were to examine CCEs' educational standards for signs of a positive and negative approach to EBP as indicated by the prevalence and use of the words evidence, research, subluxation and vitalism, and to make recommendations if significant deficiencies were found. Method We undertook a systematic audit of the educational standard documents of the various CCEs. CCEs were selected on the basis of the World Health Organisation. Two investigators identified the occurrences of terms explicitly related to EBP: evidence, evidence-based, research, subluxation and vitalism. This information was tabulated for comparative purposes. The date of the study was March 2016. Results Occurrences of the term evidence, as it related to EBP, was highest in the CCE-Europe (n = 6), followed by CCE-Australia (n = 2), and CCE-USA (n = 1). None were found in the CCE-International or CCE-Canada documents. The term research appeared most frequently in the CCE-Europe documents (n = 43), followed by CCE-USA (n-32), CCE-Australia (n = 29), CCE-Canada (n = 9) and CCE-International (n = 8). The term subluxation was found only once (CCE-USA) and vitalism did not appear in any educational standard documents. Conclusions Accreditation bodies are powerfully positioned to act as a driver for education providers to give greater priority to embedding EBP into entry-level programs and shaping future directions within the profession. Terminology relating explicitly to EBP appears to be lacking in the educational standard documentation of CCEs. Therefore, future revisions of accreditation standards should address lack of terminology

Attempting to explore chiropractors and their clinical choices: An examination of a failed study

Background Recent studies have shown that psychological factors, attitudes and beliefs impact on the quality of chiropractic student clinical decisions. This association has not been studied among qualified chiropractors. Our objective was to investigate if personality, psychological factors and/or unorthodox beliefs among chiropractors are related to choices of management in specific clinical scenarios. Method In February 2018, a subsample of chiropractors (N = 700) from a practitioner-based research network in Australia known as ACORN (N = 1680), were invited to respond to an on-line anonymous questionnaire. Questions included items relating to management of specific clinical scenarios, intolerance of uncertainty (IU) and the 'Big-5' personality score, adoption of a prescriptive technique system, self-rating of chiropractic abilities, and the level of importance of subluxation and chiropractic philosophy in the delivery of care. Descriptive analysis was to be reported and associations examined between i) personality and psychology factors, unorthodox beliefs and ii) scores obtained for management of specific clinical scenarios, numbers of interdisciplinary referrals, and guideline-based X-ray use. Results The number of respondents was 141 (20%) and 33 of their responses were largely incomplete resulting in a final response rate of 108 (15.4%). In addition, some questions were left unanswered. These related mainly to IU and Big-5 personality measurements. Some sample characteristics (age, number of patients per week, hours worked per week) were similar to the larger ACORN project sample. However, the low response rate indicated that the final study sample was unlikely to be truly representative of the study population and the low number of participants made association testing unsuitable. Conclusion and recommendations The low response rate and small study sample in this study made any substantive analysis inappropriate. For these reasons, the study was not concluded. However, the potential reasons for the low response from this large database of volunteer research participants are of interest and need to be investigated. Clearly, it is necessary to engage this population better to explore sensitive issues such as personality inventories and different practice profiles in the interest of effective health care delivery and patient safety

Similarities and differences of a selection of key accreditation standards between chiropractic councils on education: A systematic review

Background Councils of Chiropractic Education (CCE) indirectly influence patient care and safety through their role of ensuring the standards of training delivered by chiropractic educational institutions. This is achieved by a process of accreditation where CCEs define and assess graduate competencies and educational standards. A previous study comparing CCE graduate competencies found variations between the CCE jurisdictions. It was proffered that variations in standards may potentially compromise patient care and safety and also inter-jurisdictional mutual recognition. This study continues the examination of CCEs by looking for similarities and differences in CCE accreditation standards. There were two purposes of this review. The first was to compare the accreditation standards, domains of accreditation standards, and components of the domains of accreditation standards as represented by the domains of "Mission, goals, vision, objectives", "Resources", "Faculty/Academic staff", "Educational program/curriculum". In addition, we compared the accreditation standards between CCEs and those of the widely accepted medical accreditation standards of the World Federation of Medical Education (WFME), in order to search for deficiencies and opportunities for improvements in these standards. The second purpose was to make recommendations, if significant deficiencies or variations were found. Method We undertook a systematic review of the similarities and differences between five CCEs' definitions of an accreditation standard and the descriptive lists of accreditation standards they have adopted. CCE selection criteria and data selection method were undertaken in a systematic manner. This information was tabulated for a comparative analysis and took place in April 2016. Results Only two CCEs had a definition of the term "accreditation / educational standard". At the domain level there was considerably more similarities than differences. The differences became more apparent when the comparisons were made at the component level. These included intended purposes of the mission statement, standards for faculty staff, requirements for clinical training by students, program budgetary autonomy and transparency, the inclusion of chiropractic philosophy and history, and which subjects should be taught in basic, behavioural and clinical sciences. Conclusions A series of recommendations were made. These included the need for an increased clarity of the required basic and clinical science subjects, teaching clinic student requirements, and faculty staff qualifications. These are proposed with the intention of creating uniform and high quality international accreditation standards for chiropractic education. Future research should compare the levels of CCEs inspection standards and processes to see if similarities and differences exist also there

The accreditation role of Councils on Chiropractic Education as part of the profession's journey from craft to allied health profession: A commentary

Background Chiropractors see themselves as well positioned to provide safe, effective and economical care for the on-going financial burden that spinal pain imposes. However, in many places of the world, the chiropractic profession continues to find itself struggling to gain acceptance as a mainstream allied health care provider. There is evidence of the existence of undesirable chiropractic practice patterns and it is in part due to some of the world’s accredited chiropractic programs. This indicated a need for scrutiny of international chiropractic educational accreditation standards, which are the responsibility of Councils on Chiropractic Education (CCEs). To this end we reviewed an emerging body of evidence about the chiropractic educational system in order to identify issues and make recommendations that may enhance professional acceptance through improved graduate outcomes and hopefully the quality of patient care. This commentary summarises the findings of that research. Main text We reviewed recent relevant studies, including our own, into the role and function of CCEs and found that there is sufficient evidence to identify areas of concern that could be addressed, at least in part, by improvements to CCEs’ educational standards and processes. Areas included a lack of definitions for key terms such as, ‘chiropractic’, ‘diagnosis’, and ‘competency’, without which there can be no common understanding at a detailed level to inform graduate competencies and standards for a matching scope of practice. Further, there is some evidence to suggest that in some cases this level of detail is avoided in order to enable a “big tent” approach that allows for a diversity of approaches to clinical care to co-exist. This combined with the held view that chiropractic is “unique”, highly valued, and best understood by other chiropractors, explains how students and practitioners can cling to ‘traditional’ thinking. This has implications for public safety and patient quality of care. Conclusion If chiropractic care is to gain mainstream acceptance worldwide then it needs to adopt, through revitalised CCE accreditation standards and processes, those of other allied healthcare professions and wholeheartedly embrace science, evidence-based practice and patient centred care
