A review of chronic pain impact on patients, their social environment and the health care system

Validity and reliability study in undergraduate healthcare students towards the solution of a neglected problem in working life: Attitude scale towards patients with chronic pain

BACKGROUND

Chronic pain is the type of pain that healthcare professionals frequently encounter. Health care students' attitudes towards pain management are not sufficient and this negatively affects their chronic pain management. When students cannot manage the chronic pain they will experience professional burnout, depersonalization, and a decrease in compassion and empathy in patient care. Therefore, the first step in improving health care students' attitudes towards patients with chronic pain is to determine their attitudes.

OBJECTIVE

This study aims to test the validity and reliability of the Scale for Healthcare Professionals' Attitudes towards Patients with Chronic Pain (HCPAPCP Scale) in healthcare students.

METHOD

This quantitative study was conducted with 205 health care students in January-February 2022. Data were collected online with Personal Information Form and the HCPAPCP Scale. To determine the reliability of the scale, internal consistency and test-retest, and for construct validity, exploratory factor analysis and confirmatory factor analysis were performed.

RESULTS

The results of the exploratory factor analysis showed that the two-factor scale consisting of 18 items, the factor structure, and the distribution of factors in items were the same as the findings of the original scale. The Cronbach's Alpha coefficient was 0.88 for the first factor and 0.74 for the second factor. Test-retest reliability was 0.60. In confirmatory factor analysis, the model had a good and acceptable fit.

CONCLUSION

We found that the HCPAPCP Scale was valid and reliable in healthcare students.

The role of cancer nurses in cancer-related pain management in Europe

Cancer pain is a common symptom in patients with cancer and can largely affect their quality of life. Pain management is important to minimize the impact of pain on daily activities. Cancer nurses are significantly involved in all steps of pain management and contribute to the success of therapy through their knowledge and expertise. While they generally play an important role in the screening, assessment, diagnosis, treatment and follow-up of patients and their (pain) symptoms, this varies from country to country in Europe. An important aspect is their role in educating patients and their families about what pain is, what impact it can have, how it can be treated pharmacologically or non-pharmacologically and what effects or problems can occur during treatment. While there is a great discrepancy between education and training opportunities for cancer nurses in different European countries, there is a continued need for education and training in pain management. Cancer is increasingly becoming a chronic disease, and the management of pain in cancer survivors will be crucial to maintain an adequate quality of life. With this, the crucial role of cancer nurses is becoming even more important.

Innovative solutions for disease management

The increasing prevalence of chronic diseases is a driver for emerging big data technologies for healthcare including digital platforms for data collection, systems for active patient engagement and education, therapy specific predictive models, optimized patient pathway models. Powerful bioelectronic medicine tools for data collection, analysis and visualization allow for joint processing of large volumes of heterogeneous data, which in turn can produce new insights about patient outcomes and alternative interpretations of clinical patterns that can lead to implementation of optimized clinical decisions and clinical patient pathway by healthcare professionals.With this perspective, we identify innovative solutions for disease management and evaluate their impact on patients, payers and society, by analyzing their impact in terms of clinical outcomes (effectiveness, safety, and quality of life) and economic outcomes (cost-effectiveness, savings, and productivity).As a result, we propose a new approach based on the main pillars of innovation in the disease management area, i.e. progressive patient care models, patient-centric approaches, bioelectronics for precise medicine, and lean management that, combined with an increase in appropriate private-public-citizen-partnership, leads towards Patient-Centric Healthcare.

How do people with chronic pain explain their use, or non-use, of pain-related healthcare services? A qualitative study of patient experiences

PURPOSE

This study aims to explore how people with chronic pain explain their use or non-use of pain-related healthcare services and their expectations of the healthcare provider, and explore how explanations and expectations vary between different levels of pain-related healthcare use.

MATERIALS AND METHODS

We conducted 20 individual semi-structured interviews with purposely sampled adults between 39 and 77 years of age with chronic pain. All interviews were audio-recorded, transcribed and analysed using a thematical template analysis approach.

RESULTS

Four key drivers for pain-related healthcare use were identified: (1) the healthcare system facilitates clinical pathways, (2) appraisal of pain-related healthcare initiatives influences future use, (3) autonomy, beliefs and values determine healthcare behaviour, and (4) recommendations from others impact healthcare behaviour. Comparing explanations across different pain-related healthcare user groups (high, medium and low) showed that perceived needs, beliefs and values, and appraisal of previous healthcare experiences differed between these groups.

CONCLUSIONS

Beliefs, pain characteristics, recommendations, and the search for a diagnostic label, often initiate pain-related healthcare use. Healthcare is modified by two interconnected systems: (1) perceived needs, beliefs and values and (2) previous healthcare experiences. Differences related to these systems could explain some of the variance in pain-related healthcare use.Implications for RehabilitationDifferent use of pain-related healthcare services for people with chronic pain could be related to differences in perceived needs, beliefs and values and appraisal of previous healthcare.It may be helpful to explore the perceived needs and beliefs of those seeking healthcare due to chronic pain.Previous healthcare experiences may impact and should be explored.

Utilization of Methods for Pain Treatment and Management Among Older Adults with Chronic Pain

BACKGROUND

Older adults have a high prevalence of chronic pain, which can have a substantial effect on their health and quality of life. Patients' use of effective pain relief methods is a central part of the treatment and management of chronic pain. The utilization of pain relief methods and their perceived effectiveness are important knowledge for treating and managing chronic pain for clinicians and older adults. However, this has been poorly investigated.

AIM

We aimed to survey the methods used by older people to treat and manage chronic pain as well as their perceived effectiveness.

METHODS

A total of 2,000 questionnaires were sent to a random sample of people aged 65 years of age or older living in Sweden and 1,141 questionnaires were returned in usable condition. A total of 433 participants reported having chronic pain and completed the Pain Management Inventory to map the use and perceived effectiveness of used treatment and management methods.

RESULTS

The prevalence of chronic pain was 38% and the most used pain treatment methods were passive approaches, i.e., rest (60%), distractions (53%), non-prescribed medicine (49%), and prescribed medicine (44%). A total of 72% of respondents used either prescribed or non-prescribed medicine. The most used active treatment was physical activity (52%). The perceived effectiveness varied to a large extent for each method, and, on average, no treatment method seemed to be more effective than any other.

CONCLUSIONS

Knowledge about the actual use of pain treatment methods and the varied perceived effectiveness can guide clinicians in recommending new approaches or alternatives to manage chronic pain in older adults. How used methods are aligned with current clinical recommendations could be further explored in the future.

Management of Chronic Pain by Occupational Therapist: A Description of Practice Profile

Background. Current state of knowledge regarding occupational therapy's contribution to chronic pain (CP) management has evolved over the past decade. Yet, has this been transferred to clinical practice? Purpose. Describe the current state of practice of CP management-specific occupational therapy. Method. An online survey was sent to occupational therapists working with CP patients. Findings. Of the 90 respondents (11.9%), 42.2% worked in primary care and 52.2% in secondary care. They reported that their primary role aimed at enabling occupation and providing vocational rehabilitation. The Canadian Model of Occupational Performance and Engagement (CMOP-E) (87.8%), semi-structured interview (86.7%), and education on energy conservation (65.6%) and postural hygiene (60.0%) were the most frequently reported conceptual model, assessment, and intervention methods. Implications. Results illustrate the diversity of current occupational therapy practice in CP management and suggest opportunities for improvement to ensure best practices are adopted, by emphasizing an occupation-based vision of health and well-being.

Chronic wound-related pain, wound healing and the therapeutic potential of cannabinoids and endocannabinoid system modulation

Chronic wounds represent a significant burden on the individual, and the healthcare system. Individuals with chronic wounds report pain to be the most challenging aspect of living with a chronic wound, with current therapeutic options deemed insufficient. The cutaneous endocannabinoid system is an important regulator of skin homeostasis, with evidence of system dysregulation in several cutaneous disorders. Herein, we describe the cutaneous endocannabinoid system, chronic wound-related pain, and comorbidities, and review preclinical and clinical evidence investigating endocannabinoid system modulation for wound-related pain and wound healing. Based on the current literature, there is some evidence to suggest efficacy of endocannabinoid system modulation for promotion of wound healing, attenuation of cutaneous disorder-related inflammation, and for the management of chronic wound-related pain. However, there is 1) a paucity of preclinical studies using validated models, specific for the study of chronic wound-related pain and 2) a lack of randomised control trials and strong clinical evidence relating to endocannabinoid system modulation for wound-related pain. In conclusion, while there is some limited evidence of benefit of endocannabinoid system modulation in wound healing and wound-related pain management, further research is required to better realise the potential of targeting the endocannabinoid system for these therapeutic applications.

Psychological, social and academic functioning in university students with chronic pain: A systematic review

OBJECTIVE

Chronic pain is a prevalent health issue among young adults; however, there is limited understanding on how it affects university students. This is the first systematic review of evidence relating to the association between chronic pain and psychological, social and academic functioning in university students. Participants: Four databases were searched for relevant published studies. Data from 18 studies including 10,069 university students, of which 2895 reported having chronic pain, were included in the synthesis. Methods: Due to heterogeneity of data and methodologies, meta-analysis was not possible; therefore, data were synthesized narratively. Results: Our findings showed that students with chronic pain have poorer psychological, social and academic functioning and quality of life, compared to students without chronic pain. Conclusions: These findings suggest that chronic pain presents a challenge in university settings. Research is urgently needed to enable an understanding of how universities can support students who experience chronic pain.

Home-Based Treatment for Chronic Pain Combining Neuromodulation, Computer-Assisted Training, and Telemonitoring in Patients With Breast Cancer: Protocol for a Rehabilitative Study

BACKGROUND

Chronic pain is a disabling symptom frequently reported in patients with breast cancer with a prevalence ranging from 25% to 60%, representing a major health issue. It has negative consequences on health status, causing psychological distress and affecting quality of life. Furthermore, the clinical management of chronic pain is often inadequate, and many patients do not benefit from the administration of pharmacological treatments. Alternative therapeutic options have been implemented to improve the psychophysical well-being of patients, including neuromodulation and complementary interventions.

OBJECTIVE

We aimed to investigate the effectiveness of a home care strategy combining computerized rehabilitation, transcranial direct current stimulation (tDCS), and remote telemonitoring via a web-based platform in patients with breast cancer suffering for chronic pain.

METHODS

A web-based structured survey aimed at monitoring chronic pain and its effect on psychological functions will be delivered to patients with breast cancer through social media and email. In total, 42 patients with breast cancer affected by chronic pain will be recruited during the medical screening visit. The patients will be randomly divided into 3 treatment groups that will carry out either tDCS only, exercise therapy only, or a combination of both over a 3-week period. All the treatments will be delivered at the patients' home through the use of a system including a tablet, wearable inertial sensors, and a tDCS programmable medical device. Using web-based questionnaires, the perception of pain (based on the pain self-efficacy questionnaire, visual analogue scale, pain catastrophizing scale, and brief pain inventory) and psychological variables (based on the hospital and anxiety depression scale and 12-item short form survey) will be assessed at the beginning of treatment, 1 week after the start of treatment, at the end of treatment, 1 month after the start of treatment, and 3 months after the start of treatment. The system's usability (based on the mobile app rating scale and system usability scale) and its involvement in the decision-making process (based on the 9-item shared decision-making questionnaire) will be also evaluated. Finally, at the end of the treatment, a digital focus group will be conducted with the 42 patients to explore their unexpressed needs and preferences concerning treatment.

RESULTS

The study project is scheduled to start in June 2023, and it is expected to be completed by August 2025.

CONCLUSIONS

We expect that the combination of tDCS and telemedicine programs will reduce pain perceived by patients with breast cancer and improve their mental well-being more effectively than single interventions. Furthermore, we assume that this home-based approach will also improve patients' participation in routine clinical care, reducing disparities in accessing health care processes. This integrated home care strategy could be useful for patients with breast cancer who cannot find relief from chronic pain with pharmacological treatments or for those who have limited access to care due to poor mobility or geographical barriers, thus increasing the patients' empowerment and reducing health care costs.

Evidence-based guideline on chronic postsurgical pain management in adult patients in resource-restricted setting, 2023: systematic review and guideline

Background

Chronic postsurgical pain (CPSP) after tissue trauma is frequent and may have a long-lasting impact on the functioning and quality of life. The development of CPSP increases the burden on both the patient and the community. This review aims to systematically review articles and, lastly, pull an evidence-based guideline for CPSP management in adult patients in resource-limited areas.

Methodology

The review was reported based on preferred reporting items for the systemic review and meta-analysis (PRISMA) protocol. A literature search was conducted from the Cochrane, PubMed/Medline, and Google Scholar databases, and other gray literature from 2010 to 2022. The conclusion was made based on the level of evidence.

Results

A total of 3521 articles were identified through the database by searching strategies. Finally, by filtering duplicates unrelated to the topics, 22 articles (9 meta-analyses and systematic reviews, 12 systematic reviews, and one cohort study) were selected on the management of CPSP in adult patients. Filtering was made based on the intervention, outcome data of the population, and methodological quality.

Conclusion

Given the complexity and multidimensional nature of chronic postsurgical pain, effective assessment, and management require a comprehensive, multiaxial approach. Adequate preoperative preparation and counseling, potential risk identification and optimization, and use of a multimodal approach, and noninvasive surgical techniques are crucial in reducing the development of chronic postsurgical pain.

Racial disparities in pain management: Historical maleficence and solutions for equity

ABSTRACT

Medical journals from the 1800s described differences in disease susceptibility, skin thickness, and pain tolerance among races. These misconceptions about biologic differences, the historical exploitation of minorities in research, and implicit biases among healthcare workers have all affected patient care. Discrepancies still exist in pain assessment and management for minority patients compared with their White counterparts and lead to poor health outcomes. By implementing specific changes in policy and practice, including standardization, implicit bias training, and building a diverse workforce, clinicians can begin to provide care that more equitably manages pain for all patients, regardless of race.

Effectiveness of remote physiotherapeutic e-Health interventions on pain in patients with musculoskeletal disorders: a systematic review

PURPOSE

To systematically review the literature on effectiveness of remote physiotherapeutic e-Health interventions on pain in patients with musculoskeletal disorders.

MATERIALS AND METHODS

Using online data sources PubMed, Embase, and Cochrane in adults with musculoskeletal disorders with a pain-related complaint. Remote physiotherapeutic e-Health interventions were analysed. Control interventions were not specified. Outcomes on effect of remote e-Health interventions in terms of pain intensity.

RESULTS

From 11,811 studies identified, 27 studies were included. There is limited evidence for the effectiveness for remote e-Health for patients with back pain based on five articles. Twelve articles studied chronic pain and the effectiveness was dependent on the control group and involvement of healthcare providers. In patients with osteoarthritis (five articles), total knee surgery (two articles), and knee pain (three articles) no significant effects were found for remote e-Health compared to control groups.

CONCLUSIONS

There is limited evidence for the effectiveness of remote physiotherapeutic e-Health interventions to decrease pain intensity in patients with back pain. There is some evidence for effectiveness of remote e-Health in patients with chronic pain. For patients with osteoarthritis, after total knee surgery and knee pain, there appears to be no effect of e-Health when solely looking at reduction of pain. Implications for rehabilitationThis review shows that e-Health can be an effective way of reducing pain in some populations.Remote physiotherapeutic e-Health interventions may decrease pain intensity in patients with back pain.Autonomous e-Health is more effective than no treatment in patients with chronic pain.There is no effect of e-Health in reduction of pain for patients with osteoarthritis, after total knee surgery and knee pain.

What matters to people with chronic musculoskeletal pain consulting general practice? Comparing research priorities across different sectors

OBJECTIVES

Chronic musculoskeletal pain (CMP) is a common condition, often consulted in general practice. Our previous study identified research priorities among people with CMP using a broad recruitment strategy. It is unclear whether these research priorities reflect specific settings, including the population in general practice. Potential dissimilarities may have important implications for future research. Therefore, the study aims to explore potential differences between the previously established research priorities compared to priorities of people with CMP consulting general practice.

METHODS

Eighty-eight people living with CMP (51 females/37 males) from four regions of Denmark were recruited when they consulted their general practitioner. Participants were presented to an online survey and asked to prioritise predefined research themes (n=14) and research questions (n=38). The prioritisations were summarised into a Top-10 research priorities and compared the Top-10 from our previous study.

RESULTS

Treatment (n=57), diagnosis (n=46), cross-sectoral management (n=39) and influence on daily life (n=39) were the most selected research themes. The most prioritised research questions regarded the effectiveness of treatments and cross-sectoral management, improving diagnostic approaches and how pain affects the individuals' mental state. Four out of ten research questions aligned with our previous Top-10.

CONCLUSIONS

Our study identified several differences in research priorities between people living with CMP from the general population and from general practice. These findings highlight the needs for investigating how different settings influence research prioritisation. This adds important knowledge for researchers and policymakers focusing on future research within the management of CMP.

Pain science and practice as a 'threshold concept' within undergraduate and pre-registration physiotherapy education: a jewel of the curriculum?

BACKGROUND

Threshold concepts describe learning experiences that transform our understanding of a concept. Threshold concepts are variously: troublesome, transformative, irreversible, integrative and bounded.

PURPOSE

The aim of this narrative review is to consider the case for characterising pain science and practice as a threshold concept within undergraduate and pre-registration physiotherapy education. This article considers the underlying tenets of threshold concepts as they relate to teaching and learning and the relative merits and limitations of characterising pain science and practice as a threshold concept within undergraduate and pre-registration physiotherapy education from both pedagogical and epidemiological perspectives. By evaluating pain, as it relates to physiotherapy education and practice, according to the five defining characteristics of a threshold concept then presenting data related to the epidemiology and impact of pain, the worthiness of characterising pain science and practice as a threshold concept will be discussed and further debate invited.

Educational needs and preferences of adult patients with acute or chronic pain: a mixed methods systematic review protocol

OBJECTIVES

This review will aim to synthesize the available quantitative and qualitative evidence on the educational needs and preferences of adult patients with acute or chronic pain.

INTRODUCTION

Acute and chronic pain are prevalent problems and are associated with significant individual and societal consequences. Education is a critical component of pain management. However, the impact of educational interventions on pain outcomes remains limited. The lack of patient input--what patients want to know and how they want to be informed--is one of the main issues underlying intervention design.

INCLUSION CRITERIA

We will include qualitative, quantitative, and mixed methods studies describing the educational needs and preferences of adult patients with acute or chronic pain.

METHODS

This review will follow the JBI guidelines for mixed methods systematic reviews. We will search MEDLINE (PubMed), Embase (Ovid), PsycINFO (Ovid), CINAHL (EBSCO), the Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science, and ProQuest Dissertations and Theses. The search strategy will commence from the year 1990 onward and there will be no language restrictions. The retrieved titles, abstracts, and full-text reports will be screened by pairs of independent reviewers. These pairs of reviewers will also independently extract data using the JBI tools for mixed methods systematic reviews. Methodological quality will be assessed using the mixed methods appraisal tool. A convergent integrated approach to synthesis and integration of the quantitative and qualitative data will be used.

Aquatic Exercise Impact on Pain Intensity, Disability and Quality of Life in Adults with Low Back Pain: A Systematic Review and Meta-analysis

BACKGROUND

Low back pain is a common, multifaceted disorder that directly affects diverse aspects of people's lives in terms of health, personal and social lives. A variety of pathological disorders, including low back pain, may benefit from hydrotherapy.

OBJECTIVE

This study aimed to systematically analyze the efficacy of aquatic exercise on pain intensity, disability, and quality of life among adults with low back pain.

DATA SOURCES

A systematic search was conducted in PubMed, Web of Science, Medline, and Scopus up to February 2023 for randomized controlled trials (RCTs) that which examined the impact of aquatic exercise. The most relevant articles were selected based on research criteria. The PEDro scale was applied to assess the quality of the included studies. Review Manager 5.3 was used for conducting all analyses.

STUDY SELECTION

Out of 856 articles, 14 RCTs (n = 484 participants; 257 in the experimental groups and 227 in the control groups) met our inclusion criteria.

RESULTS

Pooled results illustrated that aquatic exercises significantly reduced pain (mean differences (MD): -3.82; p < 0.00,001), improved disability (standardized mean differences (SMD): 1.65; p < 0.00,001), and improved quality of life in both the physical component score (mean difference (MD), 10.13; p < 0.00,001) and the mental component score (MD, 6.45; p < 0.0001) when compared with a control group.

CONCLUSION

The current review showed that aquatic exercise regimens were effective among adults with low back pain. High-quality clinical investigations are still needed to support the use of therapeutic aquatic exercise in a clinical setting.

The experience of pain and its ontological modelling from a philosophical point of view: Phenomenological description and ontological revision of the McGill Pain Questionnaire

The aim of the article is to identify, on the basis of the phenomenological and ontological analysis of the experience of pain and the ways in which this experience is expressed in natural language, an ontological modelling of the language of pain and, at the same time, a revision of the traditional version of the McGill questionnaire. The purpose is to provide a different characterisation and an adequate evaluation of the phenomenon of pain, and, consequently, an effective measure of the actual experience of the suffering subject.

Sleep disturbances are associated with pain intensity and pain-related functional interference in patients experiencing orofacial pain

BACKGROUND

Sleep and pain have a reciprocal relationship, interacting with psychosocial aspects including depression, anxiety, somatization and significant stressful events.

OBJECTIVE

The aim of this study was to assess patients with oro-facial pain (OFP) and related sleep disturbances and determine the strongest psychosocial correlates.

METHODS

A cross-sectional study of anonymized data of consecutive patients with OFP {January 2019 and February 2020} were analysed. Diagnostic and Axis-II data were integrated to assess the relationship between sleep disturbances, measured using Chronic Pain Sleep Inventory, and demographic factors, clinical comorbidities, recent stressful events, pain severity and pain- and psychological-related function.

RESULTS

Five out of six patients with OFP were presented with pain-related sleep disturbances. Sleep problems were enhanced in patients with primary oro-facial headache compared with other OFP conditions. However, once the level of pain intensity and interference was accounted for, primary headache, was not a significant correlate of pain-related sleep disturbances. Multivariate analysis revealed (average) pain severity and pain interference were both significantly associated with sleep problems. There were also significant independent associations of sleep problems with somatization levels and reported experience of recent stressful events.

CONCLUSION

Identifying sleep problems as a part of OFP management may be beneficial and could result in better management outcomes.

Measuring PROMIS pain interference in German patients with chronic conditions: calibration, validation, and cross-cultural use of item parameters

PURPOSE

To calibrate the item parameters of the German PROMIS® Pain interference (PROMIS PI) items using an item-response theory (IRT) model and investigate psychometric properties of the item bank.

METHODS

Forty items of the PROMIS PI item bank were collected in a convenience sample of 660 patients, which were recruited during inpatient rheumatological treatment or outpatient psychosomatic medicine visits in Germany. Unidimensionality, monotonicity, and local independence were tested as required for IRT analyses. Unidimensionality was examined using confirmatory factor analyses (CFA) and exploratory factor analysis (EFA). Unidimensional and bifactor graded-response IRT models were fitted to the data. Bifactor indices were used to investigate whether multidimensionality would lead to biased scores. To evaluate convergent and discriminant validity, the item bank was correlated with legacy pain instruments. Potential differential item functioning (DIF) was examined for gender, age, and subsample. To investigate whether U.S. item parameters may be used to derive T-scores in German patients, T-scores based on previously published U.S. and newly estimated German item parameters were compared with each other after adjusting for sample specific differences.

RESULTS

All items were sufficiently unidimensional, locally independent, and monotonic. Whereas the fit of the unidimensional IRT model was not acceptable, a bifactor IRT model demonstrated acceptable fit. Explained common variance and Omega hierarchical suggested that using the unidimensional model would not lead to biased scores. One item demonstrated DIF between subsamples. High correlations with legacy pain instruments supported construct validity of the item bank. T-scores based on U.S. and German item parameters were similar suggesting that U.S. parameters could be used in German samples.

CONCLUSION

The German PROMIS PI item bank proved to be a clinically valid and precise instrument for assessing pain interference in patients with chronic conditions.

Cross-sectional Study Exploring Vision-related Quality of Life in Dry Eye Disease in a Norwegian Optometric Practice

SIGNIFICANCE

Dry eye disease causes ocular pain, blurred vision, reduced visual quality of life, and reduced workplace performance. This disease is underreported and underdiagnosed despite being highly prevalent in optometric care.

PURPOSE

This study aimed to explore the vision-related quality of life of patients with dry eye disease and the potential benefits of screening for dry eye disease in Norwegian optometric practice.

METHODS

This study adopted an observational, prospective, cross-sectional design. All patients between 18 and 70 years of age who were examined between June 8 and July 5, 2018, at Erøy Optikk, Kristiansand, Norway, were invited to participate. Dry eye disease was assessed according to Tear Film & Ocular Surface Society International Dry Eye Workshop II report recommendations. Vision-related quality of life was assessed with the National Eye Institute 25-item Visual Function Questionnaire.

RESULTS

Forty-nine patients participated in the study; 29 (59%) were female, and 29 (59%) had dry eye disease. The patients with dry eye disease reported significantly more ocular pain and (vision-specific) role difficulties than the patients without dry eye disease. After adjusting for age, sex, and habitual visual acuity, dry eye disease was found to be an independent predictor of both ocular pain ( r2 = 0.328, P = .001) and (vision-specific) role difficulties ( r2 = 0.240, P = .02). Both habitual visual acuity and dry eye disease were predictors of reduced general vision, a reduced score for near activity and reduced (vision-specific) mental health.

CONCLUSIONS

Dry eye disease was an independent predictor of ocular pain (vision-specific), role difficulties, and reduced general vision, near vision, and (vision-specific) mental health. Optometrists should consider dry eye disease as a cause of reduced vision and quality of vision. Furthermore, we propose that screening for dry eye disease in Norwegian optometric practice can promote better vision and health among patients.

The Effect of Preoperative Pain Fear on Postoperative Pain, Analgesic Use, and Comfort Level

BACKGROUND

Preoperative assessment of pain fear could provide essential information for improving perioperative care and could be the first step toward targeted pain management.

AIMS

The aim of this study is to determine the effect of preoperative pain fear on postoperative pain, analgesic use, and comfort level.

METHOD

This cross-sectional study was conducted with 201 patients in the general surgery service between January 2022 and March 2022. A sociodemographic questionnaire, Visual Analog Scale (VAS), pain fear, and general comfort scales were used for data collection. Correlation analysis was performed to examine the relationship between scales, and p < .05 was considered statistically significant.

RESULTS

The mean age of the individuals participating in the study was 51.22±15.89 and 69.2% of them were women. The average score of pain fear was 63.77±21.47, and the average score of the VAS was 7.63±1.82 after the surgery before analgesics and 5.06±1.58 six hours after surgery. The mean comfort level was 132.88±9.26. A significant and positive correlation was detected between the total pain fear and the VAS score, analgesic use, and comfort level (p < .05).

CONCLUSIONS

In this research, findings demonstrated that as the patients' pain fear increased, postoperative pain severity and amount of analgesia increased. Providing pain management with analgesics increases comfort in patients, but it may cause secondary problems in patients who use high-dose analgesics. Therefore, reducing pain fear, which is one of the main factors in pain, is essential in pain management.

Work-family conflicts and pain interference among midlife adults: a longitudinal serial mediation via family strain and loneliness

OBJECTIVE

Work-family conflict has been shown to adversely affect individuals' health and function, particularly among individuals with chronic pain. The current study's longitudinal serial mediation model examined whether work-to-family conflict predicted greater pain interference through higher levels of family strain and loneliness among midlife adults with chronic pain.

METHODS AND MEASURES

The study consisted of 303 participants from two waves of the national longitudinal study of Midlife in the United States (MIDUS) at wave II from 2004 to 2006 (Mage = 57, SD = 11) and wave 3 from 2013 to 2014 (Mage = 66, SD = 11). Participants were employed at time 1 and had chronic pain at both time points, and 54.5% of participants identified as female.

RESULTS

Family strain at time 1 (T1) and loneliness at time 2 (T2), respectively, significantly mediated the association of work-to-family conflict (T1) on pain interference at T2. Participants with greater work-to-family conflict perceived more family strain, felt lonelier, and, in turn, reported experiencing higher interference from chronic pain.

CONCLUSION

Results suggest that unmanaged work-to-family conflict could be a risk factor that exacerbates chronic pain symptoms through worsening family relationships and loneliness among midlife adults with chronic pain.

Precise management system for chronic intractable pain patients implanted with spinal cord stimulation based on a remote programming platform: study protocol for a randomized controlled trial (PreMaSy study)

BACKGROUND

Spinal cord stimulation (SCS) is a surgical technique used in patients with chronic intractable pain, and its effectiveness and safety have been validated by multiple studies. However, to maintain an optimal and steady long-term effect is still challenging. Here, we report a new management paradigm integrating smartphone application and remote programming. Chronic pain patients with SCS implants can monitor their pain status on the phone and change stimulation parameters accordingly. The PreMaSy study is a randomized controlled trial to evaluate the clinical effectiveness and safety of this precise management system.

METHODS

Patients with chronic intractable pain will be screened for eligibility, and 82 participants are anticipated to be enrolled in this trial. After the electrode implantation, the stimulation effectiveness will be tested. Participants with a reduction of more than 50% in the visual analog scale (VAS) will receive implantation of an implantable pulse generator and randomized (1:1) into the experimental group or control group. All participants will be asked to take online follow-ups and complete assessments using a smartphone application. Daily pain characteristic assessments and monthly quality of life questionnaires are integrated into the App, and participants will be required to complete these assessments. The daily VAS for pain intensity will be monitored and a threshold will be set based on baseline VAS score. The interventional appointment will be scheduled once the threshold is reached. The primary outcome is the health condition and quality of life assessed by the five-level EuroQol five-dimensional questionnaire (EQ-5D-5L). Utility values of EQ-5D-5L will be assessed at baseline and 1, 3, and 6 months post-operative.

DISCUSSION

The PreMaSy study aims to evaluate the effectiveness and safety of a novel App-based, patient-centered, self-assessment management system for chronic intractable pain. A randomized controlled trial is designed to test the non-inferiority of this precise management system compared to the monthly online follow-ups. It is also expected to yield valuable experiences regarding precision medicine.

Health profile of workers from different industries in Singapore

Introduction

Workplace safety and health are interrelated - a worker who is not healthy may cause safety lapses at the workplace; conversely, safety lapses could affect the health of the workers. This study was part of a larger Total Workplace Safety and Health (WSH) programme run by the Workplace Safety and Health Council, Singapore. The objectives were to obtain a baseline health profile of workers across four major industries and identify important health risks for targeted workplace interventions.

Methods

Five service providers (SPs) were appointed to run the Total WSH programme. As part of the programme, SPs conducted an anonymous basic health survey among workers of participating companies.

Results

The responses of 6,373 respondents from the cleaning, construction, manufacturing, and transport and storage industries were studied. The overall response rate was 62%. Key health issues identified were high rates of obesity (22%) and smoking (24%) and low prevalence of regular exercise and healthy dietary habits. Chronic disease rates were similar to population self-reported rates (hypertension 15%, high lipid 12% and diabetes mellitus 6%). The workers reported high work stress (13%).

Conclusion

Health issues are prevalent in the workforce and may affect work and employee safety. It is increasingly important for employees' health to be considered in risk assessments and prioritised in workplace safety and health management systems and strategies. Health promotion interventions should be targeted, and multilevel and multicomponent initiatives should be integrated with pre-existing occupational safety programmes.

Factors associated with general practitioner visits for pain in people experiencing chronic pain

Introduction Patients with chronic pain (CP) are frequent users of general practitioners (GPs). Aim This study aimed to assess factors associated with the rate of GP visits related to pain in patients with CP. Methods This study used data collected by adult specialist pain management services (SPMS) that participated in the electronic Persistent Pain Outcomes Collaboration (ePPOC) in Australia. Adult patients (18 years or older) with CP (duration greater than 3 months) who were referred to SPMS from the calendar year 2015-2021 were included (N  = 84 829). Results Patients who reported severe anxiety, stress, pain, pain interference, pain catastrophising and severely impaired pain self-efficacy were more likely to seek help from a GP. Patients with longer pain duration had a lower rate of GP visits. The rate of GP visits was 1.22 (IRR = 1.22, 95% CI: 1.19, 1.26) times higher in patients with severe pain severity, compared to patients with mild pain severity. Patients who used opioids were more likely to visit a GP (IRR = 1.32, 95% CI: 1.30, 1.34) than those who were not using opioids. Discussions More than half of the adult CP patients had greater than three GP visits in the 3 months before referral. This study would indicate that some patients may attend their GP to seek an opioid prescription. Given the rising use of opioids nationally, future study is required on opioid users' GP visitation practices. Additionally, the inverse association between pain duration and the rate of GP visits warrants further exploration.

Simultaneous application of lidocaine and ketamine during ambulatory infusion therapy: a retrospective analysis

Background: Infusions with lidocaine or ketamine have been separately established in the treatment of chronic pain. This study aims to retrospectively evaluate the effect of combined infusions of lidocaine and ketamine. Materials & methods: Patient records were screened for receipt of combined ambulatory infusions of lidocaine and ketamine from 2012 through 2021. A scoring system was designed to assess pain response retrospectively. Results: A total of 319 patients were included. Median pain reduction in days was 10.00 (interquartile range: 13.25). Side effects were limited to the acute phase of infusions. A total of 41.4% of patients who received concomitant pain medication reported a dose reduction. Conclusion: Our data support combined infusions as a safe therapy option, with good short-, medium- and long-term reductions in pain and great heterogeneity in treatment response. Clinical trial registration: ClinicalTrials.gov (NCT05103319).

Virtual care exercise interventions in multidisciplinary chronic pain clinics: a qualitative study of perspectives of adults living with chronic pain

PURPOSE

Chronic pain affects 1 in 4 Canadians and is a leading contributor of disability. Although virtual care has become more prevalent, it is unclear how adults living with chronic pain perceive virtual delivery of exercise interventions within multidisciplinary chronic pain clinics (MCPC). This study explores the perspectives of adults living with chronic pain regarding their perceived barriers and facilitators and recommendations when implementing virtual care exercise interventions within MCPCs.

METHODS

We conducted an interpretive description qualitative study based on semi-structured interviews with adults (age ≥18 years) living with chronic pain from a MCPC in Toronto, Canada, between March 1 and April 30, 2021.

RESULTS

We completed fifteen (N = 15) interviews of adults living with chronic pain. We identified eight themes that addressed the study objectives: 1) virtual care supplements in-person care, 2) virtual care improves accessibility, 3) impact of technology on participation, 4) navigating the home environment, 5) impact of pain on participation, 6) impact of supervision and feedback, 7) the need for tailored care, and 8) the need for preparation and additional support.

CONCLUSION

Our results reveal that adults living with chronic pain view virtual care exercise interventions positively however, the implementation of these interventions must be carefully considered within MCPCs. Specifically, virtual care was considered an excellent adjunct to in-person care but should not replace it completely.Implications for RehabilitationChronic pain is a leading contributor of disability.Exercise interventions are recommended component of comprehensive pain management.Virtual delivery of exercise interventions are becoming more prevalent.Adults living with chronic pain view virtual care exercise interventions positively as they can supplement in-person care and improve access to this type of care.

Psychological therapies delivered remotely for the management of chronic pain (excluding headache) in adults

BACKGROUND

Chronic pain (pain lasting three months or more) is an unpleasant sensory and emotional experience associated with actual or potential tissue damage. Common types (excluding headache) include back pain, fibromyalgia, and neuropathic pain. Access to traditional face-to-face therapies can be restricted by healthcare resources, geography, and cost. Remote technology-based delivery of psychological therapies has the potential to overcome treatment barriers. However, their therapeutic effectiveness compared to traditional delivery methods requires further investigation.

OBJECTIVES

To determine the benefits and harms of remotely-delivered psychological therapies compared to active control, waiting list, or treatment as usual for the management of chronic pain in adults.

SEARCH METHODS

We searched for randomised controlled trials (RCTs) in CENTRAL, MEDLINE, Embase, and PsycINFO to 29 June 2022. We also searched clinical trials registers and reference lists. We conducted a citation search of included trials to identify any further eligible trials.

SELECTION CRITERIA

We included RCTs in adults (≥ 18 years old) with chronic pain. Interventions included psychological therapies with recognisable psychotherapeutic content or based on psychological theory. Trials had to have delivered therapy remote from the therapist (e.g. Internet, smartphone application) and involve no more than 30% contact time with a clinician. Comparators included treatment as usual (including waiting-list controls) and active controls (e.g. education).

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methodological procedures.

MAIN RESULTS

We included 32 trials (4924 participants) in the analyses. Twenty-five studies delivered cognitive behavioural therapy (CBT) to participants, and seven delivered acceptance and commitment therapy (ACT). Participants had back pain, musculoskeletal pain, opioid-treated chronic pain, mixed chronic pain, hip or knee osteoarthritis, spinal cord injury, fibromyalgia, provoked vestibulodynia, or rheumatoid arthritis. We assessed 25 studies as having an unclear or high risk of bias for selective reporting. However, across studies overall, risk of bias was generally low. We downgraded evidence certainty for primary outcomes for inconsistency, imprecision, and study limitations. Certainty of evidence ranged from moderate to very low. Adverse events were inadequately reported or recorded across studies. We report results only for studies in CBT here. Cognitive behavioural therapy (CBT) versus treatment as usual (TAU) Pain intensity Immediately after treatment, CBT likely demonstrates a small beneficial effect compared to TAU (standardised mean difference (SMD) -0.28, 95% confidence interval (CI) -0.39 to -0.16; 20 studies, 3206 participants; moderate-certainty evidence). Participants receiving CBT are probably more likely to achieve a 30% improvement in pain intensity compared to TAU (23% versus 11%; risk ratio (RR) 2.15, 95% CI 1.62 to 2.85; 5 studies, 1347 participants; moderate-certainty evidence). They may also be more likely to achieve a 50% improvement in pain intensity (6% versus 2%; RR 2.31, 95% CI 1.14 to 4.66; 4 studies, 1229 participants), but the evidence is of low certainty. At follow-up, there is likely little to no difference in pain intensity between CBT and TAU (SMD -0.04, 95% CI -0.17 to 0.09; 8 studies, 959 participants; moderate-certainty evidence). The evidence comparing CBT to TAU on achieving a 30% improvement in pain is very uncertain (40% versus 24%; RR 1.70, 95% CI 0.82 to 3.53; 1 study, 69 participants). No evidence was available regarding a 50% improvement in pain. Functional disability Immediately after treatment, CBT may demonstrate a small beneficial improvement compared to TAU (SMD -0.38, 95% CI -0.53 to -0.22; 14 studies, 2672 participants; low-certainty evidence). At follow-up, there is likely little to no difference between treatments (SMD -0.05, 95% CI -0.23 to 0.14; 3 studies, 461 participants; moderate-certainty evidence). Quality of life Immediately after treatment, CBT may not have resulted in a beneficial effect on quality of life compared to TAU, but the evidence is very uncertain (SMD -0.16, 95% CI -0.43 to 0.11; 7 studies, 1423 participants). There is likely little to no difference between CBT and TAU on quality of life at follow-up (SMD -0.16, 95% CI -0.37 to 0.05; 3 studies, 352 participants; moderate-certainty evidence). Adverse events Immediately after treatment, evidence about the number of people experiencing adverse events is very uncertain (34% in TAU versus 6% in CBT; RR 6.00, 95% CI 2.2 to 16.40; 1 study, 140 participants). No evidence was available at follow-up. Cognitive behavioural therapy (CBT) versus active control Pain intensity Immediately after treatment, CBT likely demonstrates a small beneficial effect compared to active control (SMD -0.28, 95% CI -0.52 to -0.04; 3 studies, 261 participants; moderate-certainty evidence). The evidence at follow-up is very uncertain (mean difference (MD) 0.50, 95% CI -0.30 to 1.30; 1 study, 127 participants). No evidence was available for a 30% or 50% pain intensity improvement. Functional disability Immediately after treatment, there may be little to no difference between CBT and active control on functional disability (SMD -0.26, 95% CI -0.55 to 0.02; 2 studies, 189 participants; low-certainty evidence). The evidence at follow-up is very uncertain (MD 3.40, 95% CI -1.15 to 7.95; 1 study, 127 participants). Quality of life Immediately after treatment, there is likely little to no difference in CBT and active control (SMD -0.22, 95% CI -1.11 to 0.66; 3 studies, 261 participants; moderate-certainty evidence). The evidence at follow-up is very uncertain (MD 0.00, 95% CI -0.06 to 0.06; 1 study, 127 participants). Adverse events Immediately after treatment, the evidence comparing CBT to active control is very uncertain (2% versus 0%; RR 3.23, 95% CI 0.13 to 77.84; 1 study, 135 participants). No evidence was available at follow-up.

AUTHORS' CONCLUSIONS

Currently, evidence about remotely-delivered psychological therapies is largely limited to Internet-based delivery of CBT. We found evidence that remotely-delivered CBT has small benefits for pain intensity (moderate certainty) and functional disability (moderate to low certainty) in adults experiencing chronic pain. Benefits were not maintained at follow-up. Our appraisal of quality of life and adverse events outcomes post-treatment were limited by study numbers, evidence certainty, or both. We found limited research (mostly low to very low certainty) exploring other psychological therapies (i.e. ACT). More high-quality studies are needed to assess the broad translatability of psychological therapies to remote delivery, the different delivery technologies, treatment longevity, comparison with active control, and adverse events.

Improvement in medical students' knowledge on chronic pain assessment through integrative learning approaches: a randomized controlled trial

Introduction

This study aimed to compare the knowledge and skills of medical students in chronic pain assessment after being trained using the PQRST (P, provoke and palliate; Q, quality; R, region and radiation; S, severity; T, time) and ACT-UP (A, activity; C, coping; T, think; U, upset; P, people) mnemonics with those using only the PQRST mnemonic.

Methods

A double-blind, randomized controlled trial was conducted at the Faculty of Medicine, Universitas Indonesia, including forty students who participated in a simulation-based chronic pain assessment workshop. Pre- and post-test scores were used to assess participants' knowledge. Two independent raters assessed the students' skills.

Results

No significant differences in knowledge or skills were observed between the groups; however, a significant improvement in the post-test scores (85.71 [71.43-95.24]) compared to the pre-test scores (61.90 [25.87-90.48]) was observed. The students reported high satisfaction with the workshop.

Conclusions

Training with the PQRST and ACT-UP mnemonics is not better than training with the PQRST mnemonic alone in improving students' knowledge and skills in chronic pain assessment. Nevertheless, this pain education workshop was beneficial for student learning. Learning of patient-oriented chronic pain assessment should be provided in a repetitive and integrative fashion using different approaches, such as lectures, demonstrations, simulations, and interactions with patients experiencing chronic pain. To conclude, mnemonics are helpful but not a primary learning tool.

Heat-stone massage for patients with chronic musculoskeletal pain: a protocol for multicenter randomized controlled trial

Introduction

Chronic musculoskeletal pain bothers the quality of life for approximately 1.71 billion people worldwide. Although pharmacological therapies play an important role in controlling chronic pain, overuse of opioids, persistent or recurrent symptoms, and pain-related disability burden still need to be addressed. Heat-stone massage is using the heated stone to stimulate muscles and ligaments followed by massage for relax, which can potentially treat the chronic musculoskeletal pain. To determine the efficacy and safety of heat-stone massage for patients with chronic musculoskeletal pain is needed.

Methods and analysis

This multicenter, 2-arm, randomized, positive drug-controlled trial will include a total of 120 patients with chronic musculoskeletal pain. The intervention group will receive a 2 week heat-stone massage, 3 times per week, whereas the control group will receive the flurbiprofen plaster twice per day for 2 weeks. The primary end point is the change in Global Pain Scale from baseline to the end of the 2 week intervention. The secondary outcomes include the pain severity (Numerical Rating Scale), pain acceptance (Chronic Pain Acceptance Questionnaire), self-management (Health Education Impact Questionnaire), self-efficacy (Pain Self-Efficacy Questionnaire), anxiety and depression (Hospital Anxiety and Depression Scale), quality of life (Short Form-36). The intention-to-treat dataset will be used for analysis.

Discussion

The pain management remains the research topic that patients always pay close attention to. This will be the first randomized clinical trial to evaluate whether heat-stone massage, a non-pharmacological therapy, is effective in the chronic musculoskeletal pain management. The results will provide evidence for new option of daily practice.

Objective wearable measures correlate with self-reported chronic pain levels in people with spinal cord stimulation systems

Spinal Cord Stimulation (SCS) is a well-established therapy for treating chronic pain. However, perceived treatment response to SCS therapy may vary among people with chronic pain due to diverse needs and backgrounds. Patient Reported Outcomes (PROs) from standard survey questions do not provide the full picture of what has happened to a patient since their last visit, and digital PROs require patients to visit an app or otherwise regularly engage with software. This study aims to assess the feasibility of using digital biomarkers collected from wearables during SCS treatment to predict pain and PRO outcomes. Twenty participants with chronic pain were recruited and implanted with SCS. During the six months of the study, activity and physiological metrics were collected and data from 15 participants was used to develop a machine learning pipeline to objectively predict pain levels and categories of PRO measures. The model reached an accuracy of 0.768 ± 0.012 in predicting the pain intensity of mild, moderate, and severe. Feature importance analysis showed that digital biomarkers from the smartwatch such as heart rate, heart rate variability, step count, and stand time can contribute to modeling different aspects of pain. The results of the study suggest that wearable biomarkers can be used to predict therapy outcomes in people with chronic pain, enabling continuous, real-time monitoring of patients during the use of implanted therapies.

Defining Personas of People Living with Chronic Pain: An Ethnographic Research Study

Introduction

Pain is the leading reason for which people seek medical care in the United States, and chronic pain (CP) affects approximately 50 million people in the US Pain perception is deeply personal, is highly correlated with behavioral and emotional disorders, and is greatly influenced by physiological and environmental factors. The patient-provider relationship can have profound implications for clinical outcomes within the context of treating CP. However, limited access to pain specialists, the complex nature of many CP-causing conditions, the absence of instruments for objective pain measurement, and the need to foster a trust-based patient-provider relationship throughout treatment pose unique challenges.

Objective

To support a more optimal CP care delivery system that leverages a healthy therapeutic patient-provider relationship, we systematically gathered deeper knowledge of the behaviors, interpersonal dynamics, home environment, values, and mindsets of people who experience CP.

Methods

We employed ethnographic research methods to collect and analyze data on views, habits, strategies, attitudes, and life circumstances of a range of participants living with CP. We aggregated, analyzed, and summarized participant data to identify trends and similarities.

Results

Our findings suggest that patients can be broadly categorized into five predominant pain typologies, or "personas", which are characterized by respective symptom durations, care management preferences, values, communication styles, and behaviors.

Conclusion

Identifying CP personas may enhance the ability to personalize CP care and help foster more robust therapeutic relationships, which may lead to greater trust, improved patient satisfaction, and better clinical outcomes.

Understanding chronic pain in the ubiquitous community: the role of open data

The combined use of social media, open data, and Artificial Intelligence has the potential to support practitioners and empower patients/citizens living with persistent pain, both as local and online communities. Given the wide availability of digital technology today, both practitioners and interested individuals can be connected with virtual communities and can support each other from the comfort of their homes. Digital means may represent new avenues for exploring the complexity of the pain experience. Online interactions of patients, data on effective treatments, and data collected by wearable devices may represent an incredible source of psychological, sociological, and physiological pain-related information. Digital means might provide several solutions that enhance inclusiveness and motivate patients to share personal experiences, limiting the sense of isolation in both rural and metropolitan areas. Building on the consensus of the usefulness of social media in enhancing the understanding of persistent pain and related subjective experiences via online communities and networks, we provide relevant scenarios where the effectiveness and efficiency of healthcare delivery might be improved by the adoption of the digital technologies mentioned above and repeated subsequently. The aim of this perspective paper is to explore the potential of open data, social media, and Artificial Intelligence in improving the prevention and management of persistent pain by adopting innovative non-biomedical approaches.

Lessons learned from the chronic pain clinic: a qualitative study of the perspectives of healthcare providers

Aim: The chronic pain clinic (CPC) was established to address chronic non-cancer pain and opioid-related harm. Materials & methods: Employing community participatory research design First Nation Metis representatives, clinicians and a researcher collectively agreed to document lessons learned from healthcare providers' perspective, 1 year post-clinic-implementation. 17 individual interviews were conducted. Results: Thematic analysis revealed that a multidisciplinary team offered client-centered care, education, counseling and multimodal treatment options. Medication reviews and case management ensured patient safety. Communication and education of community providers enhanced pain management capacity ensuring safe opioid prescribing. Evidence-based best practices were implemented through system-level monitoring. Access to Indigenous healing strategies provided culturally responsive spiritual care upon request. Conclusion: The multidisciplinary and multimodal CPC care model effectively manages chronic non-cancer pain.

"It's like a nail being driven in the ankle": A qualitative study of individuals' lived experiences to inform a core domain set for ankle osteoarthritis

OBJECTIVES

Explore individuals' lived experience with ankle osteoarthritis and to identify health-related domains for ankle osteoarthritis based on the perspectives of people living with the condition, as an initial step to address the International Foot and Ankle Osteoarthritis Consortium's recommendation to develop a core domain set for ankle osteoarthritis.

METHODS

A qualitative study using semi-structured interviews was conducted. Interviews were undertaken with individuals with symptomatic ankle osteoarthritis who were aged ≥35 years. Interviews were recorded, transcribed verbatim and thematically analysed.

RESULTS

Twenty-three individuals (16 females; mean (range) age 62 (42-80) years) were interviewed. Five themes were identified: pain, often severe, is a central feature of living with ankle osteoarthritis; stiffness and swelling are key symptoms; ankle osteoarthritis induced mobility impairments compromise enjoyment in life; ankle osteoarthritis instability and balance impairments lead to concerns about falling; there are financial implications of living with ankle osteoarthritis. We propose 17 domains based on individuals' experiences.

CONCLUSION

Study findings indicate that individuals with ankle osteoarthritis live with chronic ankle pain, stiffness and swelling which affect their ability to participate in physical, and social activities, maintain an active lifestyle, and work in physical occupations. From the data, we propose 17 domains that are important to people with ankle osteoarthritis. These domains require further evaluation to ascertain their inclusion in a core domain set for ankle osteoarthritis.

Chronic pain among older adults and its impact on satisfaction with social participation: development and validation of the "Instrument to Assess Older Adults' Social Participation". A descriptive quantitative study

BACKGROUND

We aimed to develop and validate a practical instrument to assess older adults' satisfaction with their social participation (SP).

DESIGN AND SETTING

This methodological validation study was conducted at a public higher education institution.

METHODS

A two-phase study was designed, developed, and validated to assess older adults' satisfaction with their SP. In the first phase, we conceptualized SP and developed an "instrument to assess older adults' satisfaction with their SP (IAPSI)," as approved by a committee of specialists, pre-tested, and partially validated. Second, we determined the IAPSI's reproducibility using Cronbach's alpha to measure internal consistency, Pearson's and Spearman's coefficients to measure correlations, the Bland-Altman plot and intraclass correlation coefficient (ICC) to measure reproducibility. We also generated a receiver operating characteristic (ROC) curve.

RESULTS

102 older adults (mean age, 87.29) participated in the first phase. Moderate internal consistency (Cronbach's alpha 0.7) and significant moderate correlations with quality of life by World Health Organization Quality of Life (WHOQOL)-bref and by WHOQOL-old social domains (Pearson's coefficients 0.54 and 0.64, respectively; P < 0.001) were found. The ROC curve indicated an IAPSI score of 17 as the threshold for the impact of pain on satisfaction with SP (83.3% sensitivity and 88.9% specificity, P < 0.001). In the second phase, 56 older adults (between 81 and 90 years old) participated. We found adequate intra- and inter-observer reproducibility for the IAPSI (ICC 0.96 and 0.78, respectively).

CONCLUSION

We have developed a practical instrument with appropriate psychometric properties to assess older adults' satisfaction with their SP.

Understanding the chronic pain journey and coping strategies that patients use to manage their chronic pain: a qualitative, patient-led, Canadian study

OBJECTIVE

To gain an insight into coping strategies that people living with chronic pain use to self-manage their pain.

DESIGN

This qualitative Patient-oriented Research study used the Patient and Community Engagement Research approach. It was conducted by people with chronic pain lived experience, ensuring that patient perspective and needs were considered and addressed throughout the research cycle. Purposeful sampling was used for recruiting individuals living with chronic pain. A focus group and one-on-one semi-structured interviews were conducted via videoconference. The data were analysed iteratively using inductive thematic analysis and narrative story analysis.

SETTING

Calgary, Alberta, Canada.

PARTICIPANTS

Eleven adult participants, between the ages of 18 and 65, who self-identified as living with chronic pain for greater than 2 years.

RESULTS

Three main themes emerged from the data: (1) the elements of chronic pain, (2) the chronic pain journey to acceptance and (3) daily coping strategies for chronic pain. Participants thought it was important to discuss these three themes because the daily coping strategies that they employed at any given time (theme 3) depended on the factors discussed in themes 1 and 2. Overlaying all of this is also a grieving process that people living with chronic pain may have to go through more than once. Participants also identified recommendations for healthcare professionals to support people living with chronic pain.

CONCLUSIONS

Dealing with chronic pain affects all aspects of a person's life and involves a grieving process. When treating patients with chronic pain, it is important for healthcare professionals to understand the journey that people living with chronic pain go through, not just coping strategies. Diagnosis is critical for a patient's acceptance and in helping them find their new normal where they can employ daily coping strategies to manage their pain.

Pre-Trauma Pain Is the Strongest Predictor of Persistent Enhanced Pain Patterns after Severe Trauma: Results of a Single-Centre Retrospective Study

Background and Objectives: Traumatic injuries are a significant public health issue worldwide, with persistent enhanced pain being a common complication following severe trauma. Persistent and chronic pain can have a profound impact on patients' quality of life, affecting physical, emotional, and social functioning. This study aimed to investigate the pain patterns of trauma patients before and after severe trauma, and identify the predictors of persisting pain after injury. Materials and Methods: A total of 596 patients of a level-one trauma centre with severe trauma were included in this study. The Trauma Outcome Profile Scale was used to assess pain severity before and after trauma, and a logistic regression analysis was performed to determine the most significant predictors of relevant pain after severe trauma. Results: The mean age of the included patients was 48.2 years, and 72% were males. The most frequent cause of injury was traffic accidents, and the mean Injury Severity Score was 17.6. Nearly half of the patients experienced reduced pain-related quality of life after trauma, with persisting pain predominantly occurring in the neck, spine, shoulder, pelvis, hip, knee, and feet. Even minor injuries led to increased pain scores. Preexisting pain before injury (OR: 5.43; CI: 2.60-11.34), older age (OR: 2.09, CI: 1.22-3.27), female gender (OR: 1.08, CI: 0.73-1.59), and high injury severity (OR: 1.80, CI: 1.20-2.69) were identified as significant predictors of enhanced pain. Conclusions: These findings highlight the importance of considering pre-existing pain, body area, and injury severity in assessing the risk of persistent pain in trauma patients.

Predictors of Multiwave Opioid Use Among Older American Adults

Background and Objectives

Despite limited analgesic benefits, long-term opioid therapy (L-TOT) is common among older adults with chronic pain. Extended opioid use poses a threat to older adults as aging metabolisms retain opioids for longer, increasing the risk of injury, overdose, and other negative health outcomes. In contrast to predictors of general opioid use, predictors of L-TOT in older adults are not well documented. We aimed to identify such predictors using all available data on self-reported opioid use in the Health and Retirement Study.

Research Design and Methods

Using 5 waves of data, respondents (N = 10,713) aged 51 and older were identified as reporting no opioid use (n = 8,621), a single wave of use (n = 1,410), or multiple waves of use (n = 682). We conducted a multinomial logistic regression to predict both single- and multiwave opioid use relative to no use. Demographic, socioeconomic, geographic, health, and health care-related factors were included in our model.

Results

Multivariable findings show that, relative to nonusers, both single- and multiwave users were significantly more likely to be younger (relative risk ratio [RRR] = 1.33; RRR = 2.88); report lower household wealth (RRR = 1.47; RRR = 2.88); live in the U.S. Midwest (RRR = 1.29; RRR = 1.56), South (RRR = 1.34; RRR = 1.58), or West (RRR = 1.46; RRR = 2.34); experience interfering pain (RRR = 1.59; RRR = 3.39), back pain (RRR = 1.35; RRR = 1.53), or arthritic pain (RRR = 1.46; RRR = 2.32); and see the doctor frequently (RRR = 1.50; RRR = 2.02). Multiwave users were less likely to be Black (RRR = 0.69) or Hispanic (RRR = 0.45), and less likely to be never married (RRR = 0.52).

Discussion and Implications

We identified demographic, socioeconomic, geographic, and health care-related predictors of chronic multiyear opioid use. Our focus on individuals taking opioids for this extended duration is novel. Differences in opioid use by geographic region and frequency of doctor visits particularly warrant attention from policy-makers and researchers. We make additional recommendations based on a sensitivity analysis limited to 2016-2020 data.

A self-guided Internet-based intervention for individuals with chronic pain and depressive symptoms: study protocol of a randomized controlled trial

BACKGROUND

Despite the existence of evidence-based therapy options for the treatment of chronic pain and comorbid depressive symptoms (e.g., CBT), many individuals remain untreated. Treatment gaps result from a lack of specialists, patient fear of stigmatization, or patient immobility. Internet-based self-help interventions could serve as an anonymous and flexible alternative treatment option. In a pilot study, chronic pain patients with comorbid depressive symptoms who used a generic Internet-based depression program showed a significant reduction in depressive symptoms (but not pain symptoms) compared to a waitlist control group. Based on these findings, we developed the low-threshold, anonymous, and cost-free Internet-based self-help intervention Lenio that is tailored to the specific needs of chronic pain patients with comorbid depressive symptoms. Lenio is accompanied by the smartphone application (app) COGITO designed to increase therapeutic success. With Lenio and COGITO addressing both chronic pain and depressive symptoms, the trial aims to increase treatment effects of online interventions for chronic pain patients by reducing both depressive symptoms and pain.

METHODS

The effectiveness of the Internet-based self-help intervention and accompanying smartphone app will be evaluated in a randomized controlled trial (RCT). A total of 300 participants will be randomized into an intervention group (Lenio/COGITO), an active control group (depression-focused smartphone app), or a waitlist control group. Assessments will be done at baseline, after an 8-week intervention period (post), and after 16 weeks (follow-up). The primary outcome is the post-assessment reduction in "pain impairment" (mean value of impairment in daily life, free time, and work) as assessed by the DSF (German pain questionnaire). Secondary outcomes will include the reduction in depressive symptoms as well as in the severity of pain.

DISCUSSION

Lenio is one of the first Internet-based interventions to reduce chronic pain and depression that will be empirically evaluated. Internet-based interventions could offer a promising alternative to conventional face-to-face psychotherapy in the treatment of chronic pain patients. The primary objective of the current study is to add essential insight into the feasibility, effectiveness, and acceptance of Internet-based interventions for people with chronic pain and depressive symptoms.

Analgesic Effect of Buprenorphine for Chronic Noncancer Pain: A Systematic Review and Meta-analysis of Randomized Controlled Trials

BACKGROUND

Buprenorphine is a partial agonist at the µ-opioid receptor and an antagonist at the delta and kappa opioid receptors. It has high affinity and low intrinsic activity at the µ-opioid receptor. Buprenorphine demonstrates no ceiling effect for clinical analgesia, but demonstrates this for respiratory depression and euphoria. It may provide effective analgesia while producing less adverse effects, making it a promising opioid analgesic. A systematic review and meta-analysis were performed to examine the analgesic efficacy of buprenorphine for patients with chronic noncancer pain.

METHODS

PubMed, MEDLNE, Embase, and the Cochrane Library were searched up to January 2022. Randomized controlled trials were included if they compared buprenorphine versus placebo or active analgesic in patients with chronic noncancer pain, where pain score was an outcome. Nonrandomized controlled trials, observational studies, qualitative studies, case reports, and commentaries were excluded. Two investigators independently performed the literature search, study selection, and data collection. A random-effects model was used. The primary outcome was the effect of buprenorphine on pain intensity in patients with chronic noncancer pain based on standardized mean difference (SMD) in pain score. Quality of evidence was assessed using the Grade of Recommendations Assessment, Development, and Evaluation (GRADE) approach.

RESULTS

Two separate literature searches were conducted for patients with and without opioid use disorder (OUD). Only one study met the search criteria for those with OUD. Fourteen randomized controlled trials were included for those without OUD. Buprenorphine was associated with reduced pain score (SMD = -0.368, P < .001, I 2 = 89.37%) compared to placebo or active analgesic. Subgroup meta-analyses showed statistically significant differences in favor of buprenorphine versus placebo (SMD = -0.404, P < .001), for chronic low back pain (SMD = -0.383, P < .001), when administered via the transdermal route (SMD = -0.572, P = .001), via the buccal route (SMD = -0.453, P < .001), with length of follow-up lasting <12 weeks (SMD = -0.848, P < .05), and length of follow-up lasting 12 weeks or more (SMD = -0.415, P < .001). There was no significant difference when compared to active analgesic (SMD = 0.045, P > .05). Quality of evidence was low to moderate.

CONCLUSIONS

Buprenorphine was associated with a statistically significant and small reduction in pain intensity compared to placebo. Both the transdermal and buccal routes provided pain relief. There was more evidence supporting its use for chronic low back pain.

The Role of Environmental Context and Physical Activity in Prescribed Opioid Use and Pain in Daily Life among Patients With Chronic Low Back Pain

BACKGROUND

Prescription opioids remain a primary treatment option for patients with chronic low back pain. However, little research has examined how patients take opioids in daily life. Behavioral economics suggest that the environmental context may contribute to patients' decisions around opioid use.

PURPOSE

This study examined the association of self-reported environmental factors and physical activity with likelihood of taking opioids, opioid dosage, and physical pain.

METHOD

Patients with chronic low back pain on long-term opioid therapy (n = 34) without significant past-year opioid-related problems completed a two-week ecological momentary assessment protocol (nobservations = 1,714).

RESULTS

Initial multilevel models revealed multiple associations for different specific contexts with opioid use and pain. In models that collapsed specific contexts into categories (where, with whom, doing what), greater occasion-level physical activity was associated with a greater likelihood of taking opioids and greater pain, and being somewhere (v. at home) was associated with taking a smaller opioid dose. At any given occasion, being with someone (v. alone) was associated with taking a larger opioid dose, but patients who spent more time with others over the entire study took fewer opioids overall. Multilevel mediation found that pain did not mediate the association of physical activity and opioid use.

CONCLUSION

Results suggest that prescribed opioid use in patients with chronic low back pain is not solely determined by pain, but influenced by environmental factors, including physical activity. Psychoeducation regarding environmental factors, including how factors may be associated with both increased and decreased use of opioids, may help patients take fewer opioids more effectively.

Impact of Electronic Chronic Pain Questions on patient-reported outcomes and healthcare utilization, and attitudes toward eCPQ use among patients and physicians: prospective pragmatic study in a US general practice setting

Objective

The Electronic Chronic Pain Questions (eCPQ) has been developed to help healthcare providers systematically capture chronic pain data. This study evaluated the impact of using the eCPQ on patient-reported outcomes (PROs) and healthcare resource utilization (HCRU) in a primary care setting, and patient and physician perceptions regarding use of, and satisfaction with, the eCPQ.

Methods

This was a prospective pragmatic study conducted at the Internal Medicine clinic within the Henry Ford Health (HFH) Detroit campus between June 2017 and April 2020. Patients (aged ≥18 years) attending the clinic for chronic pain were allocated to an Intervention Group to complete the eCPQ in addition to regular care, or a control group to receive regular care only. The Patient Health Questionnaire-2 and a Patient Global Assessment were assessed at baseline, 6-months, and 12-months study visits. HCRU data were extracted from the HFH database. Telephone qualitative interviews were conducted with randomly selected patients and physicians who used the eCPQ.

Results

Two hundred patients were enrolled, 79 in each treatment group completed all 3 study visits. No significant differences (p > 0.05) were found in PROs and HCRU between the 2 groups. In qualitative interviews, physicians and patients reported the eCPQ as useful, and using the eCPQ improved patient-clinician interactions.

Conclusion

Adding the eCPQ to regular care for patients with chronic pain did not significantly impact the PROs assessed in this study. However, qualitative interviews suggested that the eCPQ was a well-accepted and potentially useful tool from a patient and physician perspective. By using the eCPQ, patients were better prepared when they attended a primary care visit for their chronic pain and the quality of patient-physician communication was increased.

Experiences of pain debut and healthcare received in men with chronic pelvic pain syndrome

BACKGROUND

Chronic Pelvic Pain Syndrome (CPPS) is the occurrence of chronic pelvic pain when there is no proven infection or other obvious local pathology that may account for the pain. It is often associated with negative cognitive, behavioural, sexual or emotional consequences, as well as with symptoms of lower urinary tract, sexual or bowel dysfunction. As there is a close link between psychosocial factors and the development of myofascial pain syndromes it is important for healthcare professionals to have knowledge of how the pain begins and the activities at the debut of the symptoms.

AIM

The aim of the study was to explore men's experiences of the process leading to CPPS and healthcare received.

METHODS

Information was obtained from semi-structured video interviews with 14 men with CPPS. Interviews were audio-recorded and transcribed. The text was then abstracted into codes and analysed with inductive content analysis.

RESULTS

The age of the informants ranged between 22 and 73 (median 48), and the duration with CPPS ranged from 1 to 46 years. Two themes emerged, one with the heading Struggling to pin it down with four subthemes and The helpful and unhelpful healthcare with two subthemes. The four subthemes show that the informants experienced difficulties in their lives in the months before the debut of symptoms, for some it was several years. They had specific triggers for the onset of pain. These included cold, trauma to the perineum, chlamydia infection and possibly secondary to a symptomatic urethral stricture. Confusion and frustration were an important element in the informants' overall experience of CPPS. Healthcare varied widely. The two subthemes about healthcare show expressions of being overlooked or wasting the doctor's time, but also the experience of being validated and being thoroughly examined.

CONCLUSION

The informants in our study described clear and specific triggers for CPPS such as being cold, having digestive issues and trauma to the perineum. Stressful events seemed to have a big impact on these informants and very possibly affected the start of symptoms. This information should be helpful healthcare professionals to understand the patient and his needs.

Patient-Reported Outcomes Measurement Information System -29 Domains Interaction in Chronic Musculoskeletal Pain During Acupuncture: A Pilot Study

Objective

This pilot study explored interactions of domains of physical, psychologic, and social factors in the Patient-Reported Outcomes Measurement Information System® (PROMIS®)-29 system and their dynamic changes during acupuncture treatment of chronic musculoskeletal pain.

Materials and Methods

PROMIS-29 profile, version 2.1 was applied among participants with chronic musculoskeletal pain, who received acupuncture treatment for 5 weeks. Data from function-oriented and symptom-oriented domains as well as changes in pain intensity were evaluated at weeks 0, 3, and 5, in 9 patients who completed full sessions. Scores of the domains were analyzed by hierarchical cluster analysis at each timepoint to identify the patterns of interactions of PROMIS domains.

Results

Hierarchical cluster analysis revealed the existence of 2 main clusters: one consisting of pain, fatigue, and emotional domains; the other comprising physical function and social domains. The general pattern was stable but interactions were found throughout the treatment. The score for sleep disturbance did not improve but was correlated with different domains at varying stages of treatment.

Conclusions

Interaction between 2 clusters of pain with fatigue and emotional domains; and physical function with social domains showed that acupuncture produces holistic reductions in chronic musculoskeletal pain. However, the limitation of sample size and bias in this pilot study requires future research on the need to adopt an interdisciplinary and holistic approach to the recovery of patients with chronic musculoskeletal pain, who have dynamic needs.

Pain and mild cognitive impairment among adults aged 50 years and above residing in low- and middle-income countries

BACKGROUND

Previous studies on the association between pain and cognitive decline or impairment have yielded mixed results, while studies from low- and middle-income countries (LMICs) or specifically on mild cognitive impairment (MCI) are scarce. Thus, we investigated the association between pain and MCI in LMICs and quantified the extent to which perceived stress, sleep/energy problems, and mobility limitations explain the pain/MCI relationship.

METHODS

Data analysis of cross-sectional data from six LMICs from the Study on Global Ageing and Adult Health (SAGE) were performed. MCI was based on the National Institute on Aging-Alzheimer's Association criteria. "Overall in the last 30 days, how much of bodily aches or pain did you have?" was the question utilized to assess pain. Associations were examined by multivariable logistic regression analysis and meta-analysis.

RESULTS

Data on 32,715 individuals aged 50 years and over were analysed [mean (SD) age 62.1 (15.6) years; 51.7% females]. In the overall sample, compared to no pain, mild, moderate, and severe/extreme pain were dose-dependently associated with 1.36 (95% CI = 1.18-1.55), 2.15 (95% CI = 1.77-2.62), and 3.01 (95% CI = 2.36-3.85) times higher odds for MCI, respectively. Mediation analysis showed that perceived stress, sleep/energy problems, and mobility limitations explained 10.4%, 30.6%, and 51.5% of the association between severe/extreme pain and MCI.

CONCLUSIONS

Among middle-aged to older adults from six LMICs, pain was associated with MCI dose-dependently, and sleep problems and mobility limitations were identified as potential mediators. These findings raise the possibility of pain as a modifiable risk factor for developing MCI.

Preclinical orofacial pain assays and measures and chronic primary orofacial pain research: where we are and where we need to go

Chronic primary orofacial pain (OFP) conditions such as painful temporomandibular disorders (pTMDs; i.e., myofascial pain and arthralgia), idiopathic trigeminal neuralgia (TN), and burning mouth syndrome (BMS) are seemingly idiopathic, but evidence support complex and multifactorial etiology and pathophysiology. Important fragments of this complex array of factors have been identified over the years largely with the help of preclinical studies. However, findings have yet to translate into better pain care for chronic OFP patients. The need to develop preclinical assays that better simulate the etiology, pathophysiology, and clinical symptoms of OFP patients and to assess OFP measures consistent with their clinical symptoms is a challenge that needs to be overcome to support this translation process. In this review, we describe rodent assays and OFP pain measures that can be used in support of chronic primary OFP research, in specific pTMDs, TN, and BMS. We discuss their suitability and limitations considering the current knowledge of the etiology and pathophysiology of these conditions and suggest possible future directions. Our goal is to foster the development of innovative animal models with greater translatability and potential to lead to better care for patients living with chronic primary OFP.

Effects of interdisciplinary pain rehabilitation programs on neuropathic and non-neuropathic chronic pain conditions - a registry-based cohort study from Swedish Quality Registry for Pain Rehabilitation (SQRP)

BACKGROUND AND AIM

Neuropathic pain arises as a direct consequence of a lesion or disease affecting the somatosensory system. Pharmacological treatments for neuropathic pain often fail despite following guidelines. Interdisciplinary Pain Rehabilitation Programs (IPRP) are an effective intervention for chronic pain conditions. Little research has investigated whether IPRP can benefit patients with chronic neuropathic pain compared to other chronic pain conditions. This study assesses the real-world effects of IPRP on patients with chronic neuropathic pain compared to non-neuropathic patients using Patient-Reported Outcome Measures (PROMs) available in the Swedish Quality Registry for Pain Rehabilitation (SQRP).

METHODS

A neuropathic group of patients (n = 1,654) were identified in two steps. This group was compared to a non-neuropathic group (n = 14,355) composed of common diagnoses (low back pain, fibromyalgia, whiplash associated disorders, and Ehlers-Danlos Syndrome) in relation to background variables, three overall outcome variables, and mandatory outcome variables (pain intensity, psychological distress symptoms, activity/participation aspects and health-related quality of life variables). Of these patients 43-44% participated in IPRP.

RESULTS

At assessment, the neuropathic group reported significantly (with small effect sizes (ES)) more physician visits the previous year, older age, shorter pain durations, and less spatial extent of the pain (moderate ES). Moreover, for the 22 mandatory outcome variables, we found only clinically insignificant differences according to ESs between the groups. For patients participating in IPRP, the neuropathic group displayed equal or in some cases slightly superior results compared to the non-neuropathic group.

DISCUSSION AND CONCLUSION

After assessing the real-world effects of IPRP, this large study found that neuropathic pain patients can benefit from the IPRP intervention. Both registry studies and RCTs are needed to better understand which patients with neuropathic pain are most suitable for IPRP and to what extent special considerations need to be made for these patients within the framework of IPRP.

A comprehensive review on clinically proven natural products in the management of nerve pain, with mechanistic insights

Introduction

People are treating their neuropathic pain with several approved and licensed pharmacological drugs. But due to having existing limitations like low efficacy with some side effects, there needs to be a more effective alternative and complementary therapeutic options.

Purpose

s: The study was designed to discuss the mechanistic role of several clinically proven natural products that have been shown to play a significant role against different nerve pain or neuropathic pain.

Method

ology: Information for this review article was salvaged using several accessible searching databases like SciVerse Scopus ® (Elsevier Properties S. A, USA), Web of Science® (Thomson Reuters, USA), and PubMed® (U.S. National Library of Medicine, USA) considering some search items like - nerve pain, natural products in pain/nerve pain management, clinically proven natural products in pain management, pain-reducing agents and so on.

Result

Our study reported the therapeutic efficacy of natural products and their possible mechanism against neuropathic pain in the human body. Natural products widely used to treat neuropathic pain include comfrey root extract ointment, lavender oil, Rose Oil, aromatic essential oil, ginger oil, vitex agnus-castus, peganum oil, and ajwain 10%. Some common pathways are involved in pain relief through sensory stimulation, enzymatic, anti-inflammatory, and pain-related receptor regulation.

Conclusion

The present study suggests that the mentioned natural products can be an appropriate choice for the treatment and management of neuropathic pain.
