The pain crisis: what it is and what can be done

An alternative theoretical approach to develop a new conception about pain in people with dementia

The theoretical approach presented in this paper describes a novel experimental-theoretical methodology to conceptualise pain in people with dementia. Existing procedures for assessment of pain rely on subjective self-report using pain questionnaires and rating scales that have proven to be highly problematic where a person has dementia. Consequently, pain in people with dementia can be undetected and/or undertreated. To address that, we have developed an alternative experimental approach that builds on theoretical and methodological precedents from the arts, humanities and social sciences, for instance, visual thinking strategies, creative thinking or two-step flow of communication. Based on this approach, we designed an experimental workshop setting to ingrate these methodologies to explore pain and its expression in people with dementia. This had led to a new definition of pain as an interruption of the socially mediated process of bodily meaning-making. Furthermore, our experimental methodology could equally well be applied as a training method, where professional staff can intervene into existing implicit meanings and understandings of medical issues. These results emphasise that the future of pain research needs to consider the relational aspects of pain more seriously.

Chronic neck and low back pain from personal experiences: a written narrative approach

Background: Chronic neck and low back pain are very common and have detrimental effects for people and society. In this study, we explore the experiences of individuals with neck and/or back pain using a written narrative methodology. Materials & methods: A total of 92 individuals explained their pain experience using written narratives. Narratives were analyzed through thematic analysis and text data mining. Results: Participants wrote about their experience in terms of pain characteristics, diagnosis process, pain consequences, coping strategies, pain triggers, well-being and future expectations. Text data mining allowed us to identify concurrent networks that were basically related with pain characteristics, management and triggers. Conclusion: Written narratives are useful to understand individuals' experiences from their point of view.

Toward consensus on pain-related content in the pre-registration, undergraduate physical therapy curriculum: a Delphi-study

BACKGROUND

Access to pain education for healthcare professionals is an International Association for the Study of Pain's key recommendation to improve pain care. The content of preregistration and undergraduate physical therapy pain curricula, however, is highly variable.

OBJECTIVE

This study aimed to develop a list, by consensus, of essential pain-related topics for the undergraduate physical therapy curriculum.

METHODS

A modified Delphi study was conducted in four rounds, including a Delphi Panel (N = 22) consisting of in pain experienced lecturers of preregistration undergraduate physical therapy of Universities of Applied Sciences in the Netherlands, and five Validation Panels. Round 1: topics were provided by the Delphi Panel, postgraduate pain educators, and a literature search. Rounds 2-4: the Delphi Panel rated the topics and commented. All topics were analyzed in terms of importance and degree of consensus. Validation Panels rated the outcome of Round 2.

RESULTS

The Delphi Panel rated 257, 146, and 90 topics in Rounds 2, 3, and 4, respectively. This resulted in 71 topics judged as "not important," 97 as "important," and 89 as "highly important." In total, 63 topics were rated as "highly important" by the Delphi Panel and Validation Panels.

CONCLUSION

A list was developed and can serve as a foundation for the development of comprehensive physical therapy pain curricula.

The Pain Medicine Curriculum Framework-structured integration of pain medicine education into the medical curriculum

Medical practitioners play an essential role in preventing pain, conducting comprehensive pain assessments, as well as promoting evidence-based practices. There is a need for the development of innovative, interprofessional and integrated pain medicine curricula for medical students. The Pain Medicine Curriculum Framework (PMCF) was developed to conceptualise a purposeful approach to the complex process of curriculum change and to prioritise the actions needed to address the gaps in pain medicine education. The PMCF comprises four dimensions: (1) future healthcare practice needs; (2) competencies and capabilities required of graduates; (3) teaching, learning and assessment methods; and (4) institutional parameters. Curricula need to meet the requirements of registration and accreditation bodies, but also equip graduates to serve in their particular local health system while maintaining the fundamental standards and values of these institutions. The curriculum needs to connect knowledge with experience and practice to be responsive to the changing needs of the increasingly complex health system yet adaptable to patients with pain in the local context. Appropriate learning, teaching and assessment strategies are necessary to ensure that medical practitioners of the future develop the required knowledge, skills and attitudes to treat the diverse needs of patients' experiencing pain. The historical, political, social and organisational values of the educational institution will have a significant impact on curriculum design. A more formalised approach to the development and delivery of a comprehensive pain medicine curriculum is necessary to ensure that medical students are adequately prepared for their future workplace responsibilities.

Top 100 Cited Publications in the Field of Temporomandibular Disorders: A Bibliometric Analysis

Background

The aim of this bibliometric research was to identify and analyze the top 100 cited publications in the field of temporomandibular disorders (TMD) in order to guide any professional level with interest in this topic by mapping the current trends in the field of TMD.

Materials and Methods

The Clarivate Analytics' Web of Science database was used to find the top 100 most cited papers in the field of TMD, published from the year 2000 to November 18, 2021, with MeSH terms in the search strategy. Data extracted were ranking, title, main author, institution, publication year, a total of citations, citation average per year, the journal the study was published, journal impact factor, and the number of studies that each journal published. Further, also the percentage of the different study designs, the number of studies regarding a specific area within the field of TMD, and the number of studies per country were also calculated. A ranking of authors was also performed.

Results

The top cited paper was a study on diagnostic criteria for TMD, with 1,287 citations published in 2014 in the Journal of Oral and Facial Pain and Headache which also had most of the top 100 cited publications. Eighty-one percent of the most cited studies were from the USA and Europe and 33% of the included studies were review articles.

Conclusion

Taken together, since all papers were considered classic, one can draw the conclusion that researchers in 2000 onward in the field of TMD are interested in (a) diagnostic criteria, (b) TMD symptoms and mainly pain-related symptoms, (c) etiology and risk factors of TMD and mainly bruxism, and (d) treatment of TMD. However, topics such as imaging, occlusion, tissue engineering, and disk displacements are presently not as popular.

No gain without pain education: Improving knowledge and biopsychosocial attitudes and beliefs in a predominantly non-health-related undergraduate target audience

OBJECTIVES

Chronic pain (CP) impacts individuals and society and is the leading cause of disability globally. Pain education interventions are often evaluated in patients and health professional students, but not in non-health student groups. Increasing knowledge of pain may facilitate shifts in attitudes and beliefs towards sufferers. We report on changes in pain knowledge, attitudes and beliefs of predominantly non-health-related tertiary degree students participating in online education.

METHODS

Quantitative cohort study design. Students reported demographics and completed the Chronic Pain Myth Scale and 12-item Neurophysiology of Pain Questionnaire (NPQ) before (T1) and after (T2) the 7-week online module at The University of Sydney in 2020.

RESULTS

Twenty-two students undertaking predominantly non-health-related bachelor's degrees (16.5% response rate, 90.9% female, mean = 19.5 years) participated. NPQ scores increased from 47.3% to 62.9%. Attitudes and beliefs towards biopsychosocial impact improved (p < 0.027) but not towards individuals suffering from CP or treatment of CP. A negative correlation was found between age and people suffering from CP (ρ = -0.437, p < 0.042) and age and towards treatment of CP; ρ = -0.556, p < 0.007) at T2.

CONCLUSION

Completing the elective online module resulted in improved knowledge and biopsychosocial attitudes towards CP in this predominantly non-health cohort, as reported in health and patient cohorts.

Self-Guided Web-Based Pain Education for People With Musculoskeletal Pain: A Systematic Review and Meta-Analysis

OBJECTIVE

The purpose of this study was to investigate the effectiveness of web-based pain education programs without clinical support in patients with musculoskeletal pain.

METHODS

PubMed, Scopus, CINAHL, Web of Science, Cochrane Library, and PsycINFO were searched from inception to February 2020. Included studies were randomized clinical trials in which people with musculoskeletal pain were allocated to an experimental group that received web-based pain education as a standalone approach. Three review authors performed data extraction. The PEDro (Physiotherapy Evidence Database) scale was used to assess the methodological quality of the studies. The primary outcomes were pain intensity and disability.

RESULTS

Six trials with a total of 1664 participants were included. There is moderate-quality evidence with a small effect size that web-based pain education programs, as a standalone approach, are better than minimal intervention (no intervention or booklets) for pain intensity (standardized mean difference [SMD] = -0.23; 95% CI = -0.43 to -0.04) in the short term and intermediate term (SMD = -0.26; 95% CI = -0.42 to -0.10). Regarding disability, there is low-quality evidence that web-based pain education programs are better than minimal intervention (SMD = -0.36; 95% CI = -0.64 to -0.07) in the short term. Web-based pain education added to usual care was no better than usual care alone in the intermediate or long term for primary outcomes.

CONCLUSIONS

Web-based pain education for adults with musculoskeletal pain, as a standalone approach, was better than minimal intervention for pain intensity and disability in the short term, and for pain intensity in the intermediate term. Web-based pain education added to usual care did not provide additional benefits for primary outcomes in the intermediate or long term.

IMPACT

Web-based pain education as a standalone intervention provided small improvements in pain intensity and disability in patients with chronic musculoskeletal pain. Poorly resourced settings and overburdened health systems should consider this delivery method in the management of chronic musculoskeletal pain.

LAY SUMMARY

If you have chronic musculoskeletal pain, your physical therapist might recommend web-based pain education as treatment to help you reduce pain intensity and disability.

Therapeutic Effects of Traditional Chinese Exercises on Musculoskeletal Pain: A Systematic Review and Meta-Analysis

Background

The number of patients with musculoskeletal pain, which seriously affects people's quality of life, has increased. Traditional Chinese exercises are accepted and practiced to strengthen the body.

Objective

This study aims to explore the efficacy of traditional Chinese exercises for the treatment of musculoskeletal pain.

Methods

A comprehensive search of randomized controlled trials (RCTs) related to traditional Chinese exercises on patients with musculoskeletal pain was completed using PubMed, SinoMed, CNKI, VIP, and Wanfang Med Online databases. All RCTs published until February 2021 were considered. Two researchers independently screened the literature according to the predesigned inclusion and exclusion criteria, and data was extracted and assessed for their risk of bias via the Cochrane collaboration tool. Meta-analysis was performed using RevMan5.2 and Rx64 4.0.2 software.

Results

A total of 45 RCT studies with 3178 patients were included. Traditional Chinese exercises were able to effectively alleviate patients with musculoskeletal pain (MD = −1.54, 95% confidence interval (−1.88, −1.19), P < 0.01). Among them, the Yi Jin Jing exercise was superior to other exercises, while Wu Qin Xi showed no significant effects. Besides, traditional Chinese exercises had significant positive effects on the dysfunction and stiffness of the waist and knee joints. Traditional Chinese exercises could effectively relieve the clinical symptoms of patients with musculoskeletal pain. Particularly, the Yi Jin Jing exercise presented the most significant positive effect on pain reduction.

Validity of Algorithms for Identification of Individuals Suffering from Chronic Noncancer Pain in Administrative Databases: A Systematic Review

BACKGROUND

Secondary analysis of health administrative databases is indispensable to enriching our understanding of health trajectories, health care utilization, and real-world risks and benefits of drugs among large populations.

OBJECTIVES

This systematic review aimed at assessing evidence about the validity of algorithms for the identification of individuals suffering from nonarthritic chronic noncancer pain (CNCP) in administrative databases.

METHODS

Studies reporting measures of diagnostic accuracy of such algorithms and published in English or French were searched in the Medline, Embase, CINAHL, AgeLine, PsycINFO, and Abstracts in Social Gerontology electronic databases without any dates of coverage restrictions up to March 1, 2018. Reference lists of included studies were also screened for additional publications.

RESULTS

Only six studies focused on commonly studied CNCP conditions and were included in the review. Some algorithms showed a ≥60% combination of sensitivity and specificity values (back pain disorders in general, fibromyalgia, low back pain, migraine, neck/back problems studied together). Only algorithms designed to identify fibromyalgia cases reached a ≥80% combination (without replication of findings in other studies/databases).

CONCLUSIONS

In summary, the present investigation informs us about the limited amount of literature available to guide and support the use of administrative databases as valid sources of data for research on CNCP. Considering the added value of such data sources, the important research gaps identified in this innovative review provide important directions for future research. The review protocol was registered with PROSPERO (CRD42018086402).

Experimental pain and fatigue induced by excessive chewing

Background

The study was aiming to optimize excessive gum chewing as an experimental model to induce jaw muscle pain and fatigue similar to those in painful TMDs with durations that would allow immediate investigations of jaw-motor function. Further, if any sex differences would be detected in the expression of pain.

Methods

This randomized, double blinded study included 31 healthy participants of both sexes. A standardized chewing protocol of either 40- or 60-min of chewing was used with a wash-out period of 1 week. Subjective fatigue, pain characteristics and functional measures were assessed. For statistical analyses, Wilcoxon Signed Rank test, Mann–Whitney Rank Sum test and Friedman’s ANOVA with Tukey post-hoc test were used.

Results

High subjective fatigue scores that lasted up to 20 min after the end of the trial were significantly induced both in the 40- and 60-min chewing trials (P <  0.001*). Significant but mild pain was induced only in the 60-min trial (P = 0.004*) and only in men (P = 0.04*). Also, the induced pain area was significantly bigger in the 60-min trial (P = 0.009*). However, this increase in pain and pain area did not last to the first 10-min follow-up. There were no significant differences neither between the 40- and 60-min chewing trials, except regarding the pain area (P = 0.008*), nor between the sexes.

Conclusion

Taken together, excessive chewing in its current form does not seem to be a proper pain experimental model. The model needs further adjustments in order to mimic TMD-pain especially in women and to prolong the pain duration.

Effects of waiting for outpatient physiotherapy services in persons with musculoskeletal disorders: a systematic review

PURPOSE

This systematic review aimed to assess the scientific evidence on the effects of waiting for outpatient physiotherapy services in persons with musculoskeletal disorders.

METHODS

A literature search was conducted in three databases (Medline, CINAHL, and Embase) for articles assessing the effects of waiting for outpatient physiotherapy services in persons with musculoskeletal disorders. Clinical and health system outcomes were analyzed.

RESULTS

Sixteen studies met the inclusion criteria for this review. The studies varied in designs, settings, and populations. The definition of waiting also varied between studies. The studies were of low to high methodological quality. Waiting for outpatient physiotherapy services was shown to have mixed results on clinical and health system outcomes. Results from included studies suggest the possible detrimental effects of waiting on pain, disability, quality of life, and psychological symptoms in persons with musculoskeletal disorders. There was also evidence of higher healthcare utilization and costs for patients who wait longer before physiotherapy services.

CONCLUSIONS

This review provides mixed evidence that suggest potential detrimental effects on the health of individuals with MSDs and at the health system level. Further high-quality studies are needed, such as longitudinal studies specifically addressing the effects of waiting due to lack of access to physiotherapy services.IMPLICATIONS FOR REHABILITATIONThe findings from this review suggest potential detrimental effects on health outcomes when patients wait longer before receiving physiotherapy services.The findings also suggest higher healthcare utilization and costs for patients with longer wait times compared to those who receive physiotherapy services more rapidly.This review suggests the need to assess and implement strategies and policies to ensure timely access to physiotherapy.

From (Ontario Ministry of Health and Long-Term Care) policy to implementation: A retrospective look at a community-based patient-centered model of care for chronic pain

Background: Chronic pain is one of the most widely recognized, disabling, and expensive health problems in Canada. Interdisciplinary multimodal pain management is effective in helping chronic pain patients lessen symptoms and reclaim functionality, but most patients lack access to such treatments.

Aim: The aim of this study was to describe the development and implementation of a publicly funded and patient-centered model of care in the community.

Methods: The study was set in the Pain & Wellness Centre (PWC) in Vaughan, the only community-based chronic pain clinic in Ontario funded by the Ontario Ministry of Health and Long-Term Care (MOHLTC) as a demonstration project of a template for similar future community clinics. The study is descriptive, including a brief review of the Ontario comprehensive pain strategy framework and an overview of the PWC and the process involved in the development of an interdisciplinary pain program (IDP), based on the biopsychosocial model of chronic pain management.

Results: During a 2.5-year period, the PWC has offered 1055 new patient medical consultations and 1921 follow-up visits and admitted 242 patients in the IDP program (demonstrating significant success in patient outcomes at the 3-month exit from the program). It established robust outcomes research, organized educational programs for pain trainees, and cultivated a collaborative relationship with the Toronto Academic Pain Medicine (TAPMI) network and the community at large.

Conclusions: This demonstration program has shown the feasibility and applicability of the principles of the MOHLTC comprehensive pain strategy, providing an effective, evidence-based, and accountable approach to chronic pain diagnosis and management in the community.

The importance of chronic pain education and awareness amongst occupational safety and health professionals

Purpose: Occupational safety and health (OSH) professionals are often the point of contact for health and safety policies derived in the workplace, and the handling of incidents in their aftermath. As chronic pain affects 20% of people, many pain-awareness campaigns and educational activities target healthcare professionals. However, initiatives directed toward OSH professionals are also important to aid in prevention and rehabilitation efforts. The objective of this study was to describe knowledge and attitudes of OSH students with regard to chronic pain. Methods: A web-based cross-sectional study was conducted amongst a convenience sample of 88 students enrolled in the distance learning OSH undergraduate certificate program at the Université du Québec en Abitibi-Témiscamingue (Quebec, Canada). Results: Although 30% of students were already employed within OSH or human resources and 40% reported intervening in cases involving chronic pain in their line of work, 56% of respondents had received no training on chronic pain and its treatment in the past five years. Only 14% chose to take the optional 45 hr course dedicated to pain within the program. OSH students also exhibited poorer knowledge and more negative attitudes toward people suffering from chronic pain when compared to other groups assessed in the province of Quebec, including healthcare professionals, chronic pain patients, and people not suffering from chronic pain (p≤0.0002). Half of the respondents (51.9%) were not aware that chronic pain affects 1 in 5 adults. Conclusion: Our study demonstrates a need for pain education within OSH training programs and through continuing education.

Contributions of Nociresponsive Area 3a to Normal and Abnormal Somatosensory Perception

Traditionally, cytoarchitectonic area 3a of primary somatosensory cortex (SI) has been regarded as a proprioceptive relay to motor cortex. However, neuronal spike-train recordings and optical intrinsic signal imaging, obtained from nonhuman sensorimotor cortex, show that neuronal activity in some of the cortical columns in area 3a can be readily triggered by a C-nociceptor afferent drive. These findings indicate that area 3a is a critical link in cerebral cortical encoding of secondary/slow pain. Also, area 3a contributes to abnormal pain processing in the presence of activity-dependent reversal of gamma-aminobutyric acid A receptor-mediated inhibition. Accordingly, abnormal processing within area 3a may contribute mechanistically to generation of clinical pain conditions. PERSPECTIVE: Optical imaging and neurophysiological mapping of area 3a of SI has revealed substantial driving from unmyelinated cutaneous nociceptors, complementing input to areas 3b and 1 of SI from myelinated nociceptors and non-nociceptors. These and related findings force a reconsideration of mechanisms for SI processing of pain.

Knowledge, Beliefs, and Attitudes of Emergency Nurses Toward People With Chronic Pain

More and more people suffering from chronic pain (CP) utilize the emergency department (ED). However, their needs are not properly addressed. Stigmatization toward people with CP can partially explain this gap. Most studies in the ED have been focused on measuring nurses' pain management knowledge in general, not negative attitudes toward CP. Hence, understanding of the determinants of the stigma related to CP is needed. The objectives of this study were to (a) describe the knowledge, beliefs, and attitudes of ED nurses toward people suffering from CP and (b) identify nurses' characteristics associated with these perceptions. A cross-sectional web-based survey design was conducted using the KnowPain-12 questionnaire and the Chronic Pain Myth Scale. A total of 571 participants from 20 different states across the United States were recruited among whom 482 completed the entire survey. The sample included about one third of the ED nurses suffering from CP. Negative beliefs and attitudes toward people with CP were present in a considerable proportion of participants (up to 64%), even in nurses suffering from CP (up to 47.5%). Nevertheless, our results suggest that higher levels of education and suffering from CP were associated with better beliefs and attitudes toward people with CP. The ED presents an increased risk of stigmatization of people with CP as compared with the general population. Identifying determinants of the stigma associated with CP is crucial, as it will help tailoring awareness and educational campaigns. In addition, CP patients utilizing the ED often have complex needs which are difficult to address in this clinical environment. This situation can contribute to negative beliefs and attitudes. Given the scarcity of specialized care clinics for this population, health-care stakeholders should devise solutions to improve continuity of care in primary care settings and between the latter and ED.

Systematic Review of Pain Medicine Content, Teaching, and Assessment in Medical School Curricula Internationally

Introduction

Pain management is a major health care challenge in terms of the significant prevalence of pain and the negative consequences of poor management. Consequently, there have been international calls to improve pain medicine education for medical students. This systematic review examines the literature on pain medicine education at medical schools internationally, with a particular interest in studies that make reference to: a defined pain medicine curriculum, specific pain medicine learning objectives, dedicated pain education modules, core pain topics, medical specialties that teach pain medicine, elective study opportunities, hours allocated to teaching pain medicine during the curriculum, the status of pain medicine in the curriculum (compulsory or optional), as well as teaching, learning, and assessment methods.

Methods

A systematic review was undertaken of relevant studies on pain medicine education for medical students published between January 1987 and May 2018 using PubMed, Medline, Excerpta Medica database (EMBASE), Education Resources Information Center (ERIC), and Google Scholar, and Best Evidence Medical Education (BEME) data bases.

Results

Fourteen studies met the inclusion criteria. Evaluation of pain medicine curricula has been undertaken at 383 medical schools in Australia, New Zealand, the United States of America (USA), Canada, the United Kingdom (UK), and Europe. Pain medicine was mostly incorporated into medical courses such as anaesthesia or pharmacology, rather than presented as a dedicated pain medicine module. Ninety-six percent of medical schools in the UK and USA, and nearly 80% of medical schools in Europe had no compulsory dedicated teaching in pain medicine. On average, the median number of hours of pain content in the entire curriculum was 20 in Canada (2009), 20 in Australia and New Zealand (2018), 13 in the UK (2011), 12 in Europe (2012/2013), and 11 in the USA (2009). Neurophysiology and pharmacology pain topics were given priority by medical schools in all countries. Lectures, seminars, and case-based instruction were the teaching methods most commonly employed. When it was undertaken, medical schools mostly assessed student competency in pain medicine using written examinations rather than clinical assessments.

Conclusions

This systematic review has revealed that pain medicine education at medical schools internationally does not adequately respond to societal needs in terms of the prevalence and public health impact of inadequately managed pain.

Characteristics and complexity of chronic pain patients referred to a community-based multidisciplinary chronic pain clinic

BACKGROUND

Community-based care fills an important service gap for patients living with chronic pain. Better understanding of unmet patient needs in the community may inform improved policy and resource allocation.

AIMS

The aim of this study was to describe patients presenting to a community-based, multidisciplinary chronic pain clinic in Vancouver, British Columbia.

METHODS

This is a retrospective cross-sectional study of 935 unique consecutive patients who completed an intake questionnaire between January 2016 and March 2017. All data were patient reported.

RESULTS

Nine hundred thirty-five patient records were analyzed for descriptive characteristics. The mean age of the population was 49.5 (SD = 14.9) years; 70% were female. Approximately 50% of patients lived below the poverty line in Vancouver; 30% were not working due to disability, 51% had pain for more than 5 years, and 63% reported severe functional impairment.

CONCLUSIONS

Substantial unmet need is demonstrated in this patient population accessing a community-based chronic pain clinic. The population described is mainly of working age with significant functional impairment, reflecting a high level of need due to severity and duration of symptoms, poverty, and other characteristics described.

Novel Pharmacological Nonopioid Therapies in Chronic Pain

PURPOSE OF REVIEW

Opioid use and abuse has led to a worldwide opioid epidemic. And while opioids are clinically useful when appropriately indicated, they are associated with a wide range of dangerous side effects and whether they are effective at treating or eliminating chronic pain is controversial. There has long been a need for the development of nonopioid alternative treatments for patients that live in pain, and until recently, only a few effective treatments were available. Today, there are a wide range of nonopioid treatments available including NSAIDs, acetaminophen, corticosteroids, nerve blocks, SSRIs, neurostimulators, and anticonvulsants. However, these treatments are still not entirely effective at treating pain, which has sparked a new exploration of novel nonopioid pharmacotherapies.

RECENT FINDINGS

This manuscript will outline the most recent trends in novel nonopioid pharmacotherapy development including tramadol/dexketoprofen, TrkA inhibitors, tapentadol, opioid agonists, Nektar 181, TRV 130, ßarrestin2, bisphosphonates, antibodies, sodium channel blockers, NMDA antagonists, TRP receptors, transdermal vitamin D, AAK1 kinase inhibition, calcitonin gene-related peptide (CGRP), TRPV4 antagonists, cholecystokinin, delta opioid receptor, neurokinin, and gene therapy. The pharmacotherapies discussed in this manuscript outline promising opioid alternatives which can change the future of chronic pain treatment.

The association between hope, marital status, depression and persistent pain in men and women following cardiac surgery

Background

Cardiac surgery is a major life event, and outcomes after surgery are associated with men’s and women’s ability to self-manage and cope with their cardiac condition in everyday life. Hope is suggested to impact cardiac health by having a positive effect on how adults cope with and adapt to illness and recommended lifestyle changes.

Methods

We did a secondary analysis of 416 individuals (23% women) undergoing elective coronary artery bypass graft and/or valve surgery between March 2012 and September 2013 enrolled in randomized controlled trial. Hope was assessed using The Herth Hope Index (HHI) at three, six and 12 months following cardiac surgery. Linear mixed model analyses were performed to explore associations after cardiac surgery between hope, marital status, depression, persistent pain, and surgical procedure.

Results

For the total sample, no statistically significant difference between global hope scores from 3 to 12 months was observed (ranging from 38.3 ± 5.1 at 3 months to 38.7 ± 5.1 at 12 months), and no differences between men and women were observed at any time points. However, 3 out of 12 individual items on the HHI were associated with significantly lower scores in women: #1) I have a positive outlook toward life, #3) I feel all alone, and #6) I feel scared about my future. Over the study period, diminished hope was associated with older age, lower education, depression prior to surgery, and persistent pain at all measurement points. Isolated valve surgery was positively associated with hope. While neither sex nor marital status, as main effects, demonstrated significant associations with hope, women who were divorced/widowed/single were significantly more likely to have lower hope scores over the study period.

Conclusion

Addressing pain and depression, and promoting hope, particularly for women living alone may be important targets for interventions to improve outcomes following cardiac surgery.

Knowledge, beliefs, and attitudes of the Quebec population toward chronic pain: Where are we now?

Background: Many chronic pain (CP) awareness and educational initiatives have been achieved, but it is time to take stock of where we are today. Aims: The aim of this study was to describe and identify determinants of knowledge, beliefs, and attitudes of different subgroups of the Quebec population regarding CP and especially toward people suffering from this condition. Methods: A web-based, cross-sectional study was conducted between May and June 2014. Results: A total of 1958 participants responded, among whom 70.9% reported suffering from CP and 14.4% reported being a health care professional (HCP). Almost half of the participants were not aware that the risk of developing CP is increased after undergoing surgery or that CP affects approximately one in five adults. A minority (10.30%) agreed that HCP are well trained in CP treatment. The two most frequent negative beliefs were that people suffering from CP become dependent on their medications as do drug addicts (16.7%) and that consulting a psychologist is useless unless the person with CP is depressed (16.9%). Multiple regression analysis showed that being a woman, being born in Canada, being unemployed, suffering from CP, and being an HCP were predictors of better knowledge and more positive attitudes toward people suffering from CP (all P values < 0.05). Older age and residing in a remote region were associated with poorer knowledge and more negative attitudes. Conclusions: Our results underline the importance of continuing the efforts and the need for more education programs, awareness campaigns, and stigma reduction activities about CP for HCP, patients, and the general public.

SCOPE of Pain: An Evaluation of an Opioid Risk Evaluation and Mitigation Strategy Continuing Education Program

OBJECTIVE

Due to the high prevalence of prescription opioid misuse, the US Food and Drug Administration (FDA) mandated a Risk Evaluation and Mitigation Strategy (REMS) requiring manufacturers of extended-release/long-acting (ER/LA) opioid analgesics to fund continuing education based on a FDA Blueprint. This article describes the Safe and Competent Opioid Prescribing Education (SCOPE of Pain) program, an ER/LA opioid analgesic REMS program, and its impact on clinician knowledge, confidence, attitudes, and self-reported clinical practice.

METHOD

Participants of the 3-h SCOPE of Pain training completed pre-, immediate post- and 2-month post-assessments.

SUBJECTS

The primary target group (n = 2,850), and a subset (n = 476) who completed a 2-month post-assessment, consisted of clinicians licensed to prescribe ER/LA opioid analgesics, who care for patients with chronic pain and who completed the 3-h training between February 28, 2013 and June 13, 2014.

RESULTS

Immediately post-program, there was a significant increase in correct responses to knowledge questions (60% to 84%, P ≤ 0.02) and 87% of participants planned to make practice changes. At 2-months post-program, there continued to be a significant increase in correct responses to knowledge questions (60% to 69%, P ≤ 0.03) and 67% reported increased confidence in applying safe opioid prescribing care and 86% reported implementing practice changes. There was also an improvement in alignment of desired attitudes toward safe opioid prescribing.

CONCLUSIONS

The SCOPE of Pain program improved knowledge, attitudes, confidence, and self-reported clinical practice in safe opioid prescribing. This national REMS program holds potential to improve the safe use of opioids for the treatment of chronic pain.

The Chronic Pain Myth Scale: Development and Validation of a French-Canadian Instrument Measuring Knowledge, Beliefs, and Attitudes of People in the Community towards Chronic Pain

Background. In order to better design awareness programs on chronic pain (CP), measurement of knowledge, beliefs, and attitudes of people in the community towards this condition is most useful. Objectives. To develop and validate a French-Canadian scale that could be used for this purpose. Methods. Items of the Chronic Pain Myth Scale (CPMS) were developed based on different information sources, reviewed by pain experts, and pretested. The CPMS was administered to 1555 participants among the general Quebec population. Results. The final CPMS contained 26 items allowing the calculation of three subscales scores (knowledge, beliefs, and attitudes towards people suffering from CP, biopsychosocial impacts of CP, and treatment of CP) which showed adequate internal consistency (α = 0.72-0.82). There were statistically significant differences in subscales scores between participants who reported suffering versus not suffering from CP, reported knowing versus not knowing someone who suffers from CP, and reported being versus not being a healthcare professional, which supports the construct validity of the scale. Conclusions. Our results provide preliminary evidence supporting the psychometric qualities of the use of the CPMS for the measurement of knowledge, beliefs, and attitudes towards CP among French-speaking individuals of the Quebec general population.

Fibromyalgia-related costs and loss of productivity: a substantial societal burden

BACKGROUND

This study aimed at describing pain-related health care resource use, direct costs, and productivity loss among patients suffering from fibromyalgia syndrome (FMS).

METHODS

A cost-of-illness study with a sample of 57 adults having a diagnosis of FMS was conducted in the province of Quebec (Canada). Data regarding FMS-related direct costs and productivity loss from paid and unpaid work over a three-month period were collected using a standardized structured telephone interview protocol. Direct costs were valued in 2009 Canadian dollars using a societal perspective.

RESULTS

Results showed that average direct costs over a three-month period added up to $951 per patient (SD: $710), which could be translated in a mean annual cost of $3804. The purchase of prescribed medications led to the highest costs (mean: $329, SD: $321), followed by consultations to health care professionals other than physicians (mean: $129, SD: $222) and physicians consultations (mean: $98, SD: $116). Results further showed a high economic burden for patients themselves, aside from costs covered by public or private insurers. Among the subsample of participants who had a paid job (45.6%), an average of 5.6 days (SD: 13.2) were lost due to pain during the past three months. Among those who were not employed (54.4%), an average of 25.1 days in household productivity (SD: 24.8) were lost.

CONCLUSIONS

FMS is associated with a substantial socioeconomic burden. Further research is clearly needed to improve the management of this type of disorder and make better decisions regarding resource allocation.

Performance and quality indicators for the management of non-cancer chronic pain: a scoping review protocol

INTRODUCTION

Chronic pain is a public health problem of epidemic proportion in most countries with important physical, psychological, social and economic consequences. The management of chronic pain is complex and requires an integrated network approach between all levels of the healthcare system and the involvement of several health professionals from different disciplines. Measuring the performance of organisations that provide care to individuals with chronic pain is essential to improve quality of care and requires the use of relevant performance and quality indicators. A scoping review methodology will be used to synthesise the evidence on performance and quality indicators developed for non-cancer chronic pain management across the continuum of care.

METHODS AND ANALYSIS

The following electronic databases will be searched from 2000 onwards: Cochrane Effective Practice and Organisation of Care (EPOC) Review Group Specialised Register; Cochrane Library; EMBASE; PubMed; CINAHL; PsycINFO; ProQuest Dissertations and Theses. All types of studies will be included if these are concerned with performance or quality indicators in adults with chronic non-cancer pain. In addition, searches will be conducted on provincial, national and international health organisations as well as health professional and scientific associations' websites. A qualitative descriptive approach will be used to describe characteristics of each indicator. All identified indicators will be classified according to dimensions covered by Donabedian and the Triple Aim frameworks.

ETHICS AND DISSEMINATION

The scoping review findings will inform the development of a performance measurement system comprising a list of performance indicators with their level of evidence which can be used by stakeholders to evaluate the quality of care for individuals with chronic non-cancer pain at the patient, institutional and system level. The results will be disseminated via several knowledge translation strategies, including 2 stakeholder meetings, publication and presentation at conferences.

Development and validation of the French-Canadian Chronic Pain Self-efficacy Scale

Self-efficacy can be defined as the belief in one’s capability to acheive certain goals. In the context of chronic pain, self-efficacy may reflect an individual’s performance with regard to self-management strategies to improve their chronic pain. The authors of this article aimed to generate a translation of the Chronic Pain Self-efficacy Scale, a validated scale used to measure self-efficacy, for use in French-Canadian populations. The internal consistency, convergent construct validity and sensitivity to change of the translated document were assessed.

BACKGROUND:

Perceived self-efficacy is a non-negligible outcome when measuring the impact of self-management interventions for chronic pain patients. However, no validated, chronic pain-specific self-efficacy scales exist for studies conducted with French-speaking populations.

OBJECTIVES:

To establish the validity of the use of the French-Canadian Chronic Pain Self-efficacy Scale (FC-CPSES) among chronic pain patients.

METHODS:

The Chronic Disease Self-Efficacy Scale is a validated 33-item self-administered questionnaire that measures perceived self-efficacy to perform self-management behaviours, manage chronic disease in general and achieve outcomes (a six-item version is also available). This scale was adapted to the context of chronic pain patients following cross-cultural adaptation guidelines. The FC-CPSES was administered to 109 fibromyalgia and 34 chronic low back pain patients (n=143) who participated in an evidence-based self-management intervention (the PASSAGE program) offered in 10 health care centres across the province of Quebec. Cronbach’s alpha coefficients (α) were calculated to determine the internal consistency of the 33- and six-item versions of the FC-CPSES. With regard to convergent construct validity, the association between the FC-CPSES baseline scores and related clinical outcomes was examined. With regard to the scale’s sensitivity to change, pre- and postintervention FC-CPSES scores were compared.

RESULTS:

Internal consistency was high for both versions of the FC-CPSES (α=0.86 to α=0.96). Higher self-efficacy was significantly associated with higher mental health-related quality of life and lower pain intensity and catastrophizing (P<0.05), supporting convergent validity of the scale. There was a statistically significant increase in FC-CPSES scores between pre- and postintervention measures for both versions of the FC-CPSES (P<0.003), which supports their sensitivity to clinical change during an intervention.

CONCLUSIONS:

These data suggest that both versions of the FC-CPSES are reliable and valid for the measurement of pain management self-efficacy among chronic pain patients.

Secondary prevention of chronic pain: can internet help?

Chronic pain is common and strongly impacts the individual and society as a whole. Although there are effective multidisciplinary treatments available, they are often not easily accessible and designed for people with severe long-lasting problems. The main aim of this paper is to propose and stimulate debate about how the internet can help to increase accessibility and promote a shift toward secondary prevention. Specifically, internet can help by providing access to educational websites containing information for professionals and the general population. Internet can also be useful for creating accessible interventions designed to reduce risk factors for the development of long-term disability. The involvement of society in general and the professionals working in the field is fundamental for advancing in this direction.

Chronic pain and health care spending: an analysis of longitudinal data from the Medical Expenditure Panel Survey

OBJECTIVE

To estimate average incremental health care expenditures associated with chronic pain by health care service category, expanding on prior research that focused on specific pain conditions instead of general pain, excluded low levels of pain, or did not incorporate pain duration.

DATA SOURCE

Medical Expenditure Panel Survey (MEPS) data (2008-2011; N = 26,671).

STUDY DESIGN

Differences in annual expenditures for adults at different levels of pain that interferes with normal work, as measured by the SF-12, were estimated using recycled predictions from two-part logit-generalized linear regression models.

PRINCIPAL FINDINGS

"A little bit" of chronic pain-related interference was associated with a $2,498 increase in total adjusted expenditures over no pain interference (p < .0001) and a $1,008 increase over nonchronic pain interference (p = .0001). Moderate and severe chronic pain-related interference was associated with a $3,707 and $5,804 increase in expenditures over no pain interference and a $2,218 and $4,315 increase over nonchronic interference, respectively (p < .0001). Expenditure increases were most pronounced for inpatient and hospital outpatient expenditures compared to other types of health care expenditures.

CONCLUSIONS

Chronic pain limitations are associated with higher health care expenditures. Results underscore the substantial cost of pain to the health care system.

Prevalence and determinants of cannabinoid prescription for the management of chronic noncancer pain: a postal survey of physicians in the Abitibi-Témiscamingue region of Quebec

BACKGROUND

Few studies have been conducted to explore physicians' prescription practices and attitudes toward the use of cannabinoids in Canada.We measured the prevalence and identified determinants of cannabinoid prescription for the management of chronic noncancer pain among physicians in southwestern Quebec.

METHODS

In February 2013, we conducted a postal survey using a modified Dillman method that involved physicians practising in the Abitibi-Témiscamingue region of Quebec. We used multivariate logistic regression models to identify determinants of cannabinoid prescription.

RESULTS

A total of 166 physicians of 318 practising in the region participated in the survey (response rate 52.2%). The prevalence of cannabinoid prescription was 27.3% (45/165) for any indication and 23.0% (38/165) for the management of chronic noncancer pain; 91.1% (41/45) of the physicians prescribed cannabinoids to 5 or fewer patients. Of the 38 physicians who prescribed cannabinoids for chronic noncancer pain, 35 (92.1%) prescribed nabilone, 7 (18.4%) medical marijuana and 2 (5.3%) nabiximols. The principal determinant of cannabinoid prescription was the physician's level of comfort with prescribing cannabinoids (adjusted odds ratio 1.25, 95% confidence interval 1.01-1.55, per 1-point increase in comfort level measured on 10-point scale). Respondents reported that continuing medical education (CME) activities could increase their comfort level. They also indicated a need for guidelines or algorithms that included cannabinoid use as well as more studies about the efficacy and safety of cannabinoids for the management of chronic noncancer pain.

INTERPRETATION

We found that cannabinoids were not often prescribed for the management of chronic noncancer pain and that survey respondents were not comfortable with prescribing this drug class. This degree of discomfort could be addressed by CME activities, more effective dissemination of guidelines and more evidence regarding cannabinoid use for the management of chronic noncancer pain.

Although unseen, chronic pain is real-A phenomenological study

Background Research has emphasised the essential role of psychosocial risk factors in chronic pain. In practice, pain is usually verified by identifying its physical cause. In patients without any distinct pathology, pain is easily defined as imaginary pain. The aim of this qualitative study was to explore the invisibility of chronic pain, from the patients' perspective. Methods Thirty-four participants with chronic pain were interviewed. The mean age of the participants was 48 years, and 19 of them were women. For 21 of the participants, the duration of pain was more than five years, and most of the participants had degenerative spinal pain. The transcribed interviews were analysed using Giorgi's four-phase phenomenological method. Results The participants' chronic pain was not necessarily believed by health care providers because of no identified pathology. The usual statements made by health care providers and family members indicated speculation, underrating, and denial of pain. The participants reported experience of feeling that they had been rejected by the health care and social security system, and this feeling had contributed to additional unnecessary mental health problems for the participants. As a result from the interviews, subthemes such as "Being disbelieved", "Adolescents' pain is also disbelieved", "Denying pain", "Underrating symptoms", "The pain is in your head", "Second-class citizen", "Lazy pain patient", and "False beliefs demand passivity" were identified. Conclusions In health care, pain without any obvious pathology may be considered to be imaginary pain. Despite the recommendations, to see chronic pain as a biopsychosocial experience, chronic pain is still regarded as a symptom of an underlying disease. Although the holistic approach is well known and recommended, it is applied too sparsely in clinical practice. Implications The Cartesian legacy, keeping the mind and body apart, lives strong in treatment of chronic pain despite recommendations. The biopsychosocial approach seems to be rhetoric.

A novel pain interprofessional education strategy for trainees: assessing impact on interprofessional competencies and pediatric pain knowledge

BACKGROUND

Health care trainees⁄students lack knowledge and skills for the comprehensive clinical assessment and management of pain. Moreover, most teaching has been limited to classroom settings within each profession.

OBJECTIVES

To develop and evaluate the feasibility and preliminary outcomes of the 'Pain-Interprofessional Education (IPE) Placement', a five-week pain IPE implemented in the clinical setting. The utility (content validity, readability, internal consistency and practical considerations) of the outcome measures was also evaluated.

METHODS

A convenience sample of 21 trainees from eight professions was recruited over three Pain-IPE Placement cycles. Pre- and postcurriculum assessment included: pain knowledge (Pediatric Pain Knowledge and Attitudes Survey), IPE attitudes (Interdisciplinary Education Perception Scale [IEPS]) and IPE competencies (Interprofessional Care Core Competencies Global Rating Scales [IPC-GRS]), and qualitative feedback on process⁄acceptability.

RESULTS

Recruitment and retention met expectations. Qualitative feedback was excellent. IPE measures (IEPS and IPC-GRS) exhibited satisfactory utility. Postcurriculum scores improved significantly: IEPS, P<0.05; IPC-GRS constructs, P<0.01; and competencies, P<0.001. However, the Pediatric Pain Knowledge and Attitudes Survey exhibited poor utility in professions without formal pharmacology training. Scores improved in the remaining professions (n=14; P<0.01).

DISCUSSION

There was significant improvement in educational outcomes. The IEPS and IPC-GRS are useful measures of IPE-related learning. At more advanced training levels, a single pain-knowledge questionnaire may not accurately reflect learning across diverse professions.

CONCLUSION

The Pain-IPE Placement is a successful collaborative learning model within a clinical context that successfully changed interprofessional competencies. The present study represents a first step at defining and assessing change in interprofessional competencies gained from Pain-IPE.
