We Are All in This Together-Whole of Community Pain Science Education Campaigns to Promote Better Management of Persistent Pain

Persistent pain is a major public health issue-estimated to affect a quarter of the world's population. Public understanding of persistent pain is based on outdated biomedical models, laden with misconceptions that are contrary to best evidence. This understanding is a barrier to effective pain management. Thus, there have been calls for public health-based interventions to address these misconceptions. Previous pain-focussed public education campaigns have targeted pain beliefs and behaviours that are thought to promote recovery, such as staying active. However, prevailing pain-related misconceptions render many of these approaches counter-intuitive, at best. Pain Science Education improves understanding of 'how pain works' and has been demonstrated to improve pain and disability outcomes. Extending Pain Science Education beyond the clinic to the wider community seems warranted. Learning from previous back pain-focussed and other public health educational campaigns could optimise the potential benefit of such a Pain Science Education campaign. Pain Science Education-grounded campaigns have been delivered in Australia and the UK and show promise, but robust evaluations are needed before any firm conclusions on their population impact can be made. Several challenges exist going forward. Not least is the need to ensure all stakeholders are involved in the development and implementation of Pain Science Education public messaging campaigns. Furthermore, it is crucial that campaigns are undertaken through a health equity lens, incorporating underrepresented communities to ensure that any intervention does not widen existing health inequalities associated with persistent pain. PERSPECTIVE: Public misconceptions about pain are a significant public health challenge and a viable intervention target to reduce the personal, social, and economic burden of persistent pain. Adaptation of Pain Science Education, which improves misconceptions in a clinical setting, into the public health setting seems a promising approach to explore.

Consumer Perceptions of Home-Based Percussive Massage Therapy for Musculoskeletal Concerns: Inductive Thematic Qualitative Analysis

BACKGROUND

Musculoskeletal pain is a prevalent concern among diverse populations, from the average individual to the elite athlete. Handheld percussive massage therapy devices like massage guns have gained much popularity in both medical and athletic settings. Its application has been prominently recognized in injury prevention and rehabilitation. The expansion of the market to provide handheld percussive therapy devices with varying features and price points has encouraged professional and novice use. While percussive therapy holds similarities to more studied therapeutic modalities, like vibration therapy and soft tissue mobilization, there is limited evidence-based information on the indications and contraindications.

OBJECTIVE

This study aims to use a qualitative analysis of consumer perceptions to understand the perceived therapeutic potential of percussive massage therapy as a home-based intervention for musculoskeletal concerns of everyday users and elite athletes. Additionally, we aim to gain insight on valuable characteristics supporting its therapeutic potential as well as pertinent limitations.

METHODS

The TOLOCO massage gun (TOLOCO) was identified as the best-selling percussive massage therapy device on Amazon. We performed an inductive thematic qualitative analysis on the top 100 positive comments and the top 100 critical comments of the device between June 2020 and April 2023 to determine 4 relevant themes.

RESULTS

The 4 themes identified upon qualitative analysis were pain management, versatility, accessibility, and safety and user education. Consumer reviews indicated use for this percussive therapy device in adolescents, adults, and older people across a spectrum of activity levels. Consumers reported the therapeutic potential of percussive massage therapy in managing wide-ranging musculoskeletal concerns like acute pain, chronic pain, nonsurgical injury rehabilitation, postsurgical injury rehabilitation, and injury prevention. Consumers highlighted the versatility of the device to address person-specific needs as a key feature in supporting its perceived therapeutic benefits. Additionally, consumers frequently commented on the affordability and availability of this device to increase accessibility to home-based care. Some critical reviews emphasized a concern for the quality of the device itself. However, this concern did not translate to the overall modality of percussive massage therapy. Of note, despite strong approval for its therapeutic potential, consumer reviews lacked evidence-based insights on appropriate usage.

CONCLUSIONS

Home-based percussive massage therapy holds value with its perceived efficacy in pain management for acute and chronic conditions, as well as in injury prevention and rehabilitation. As a low-cost and readily available device for everyday users and high-performing athletes, percussive massage therapy works toward establishing increased health care accessibility and optimizing health care usage. This home-based intervention can serve to reduce the significant personal and economic burden of prevalent musculoskeletal concerns. However, the limited scientific research on percussive massage therapy raises concerns about the lack of evidence-based care and indicates the need for future studies.

Socioeconomic Status, Knee Pain, and Epigenetic Aging in Community-Dwelling Middle-to-Older Age Adults

Chronic musculoskeletal pain is often associated with lower socioeconomic status (SES). SES correlates with psychological and environmental conditions that could contribute to the disproportionate burden of chronic stress. Chronic stress can induce changes in global DNA methylation and gene expression, which increases risk of chronic pain. We aimed to explore the association of epigenetic aging and SES in middle-to-older age individuals with varying degrees of knee pain. Participants completed self-reported pain, a blood draw, and answered demographic questions pertaining to SES. We used an epigenetic clock previously associated with knee pain (DNAmGrimAge) and the subsequent difference of predicted epigenetic age (DNAmGrimAge-Diff). Overall, the mean DNAmGrimAge was 60.3 (±7.6), and the average DNAmGrimAge-diff was 2.4 years (±5.6 years). Those experiencing high-impact pain earned less income and had lower education levels compared to both low-impact and no pain groups. Differences in DNAmGrimAge-diff across pain groups were found, whereby individuals with high-impact pain had accelerated epigenetic aging (∼5 years) compared to low-impact pain and no pain control groups (both ∼1 year). Our main finding was that epigenetic aging mediated the associations of income and education with pain impact, as such the relationship between SES and pain outcomes may occur through potential interactions with the epigenome reflective of accelerated cellular aging. PERSPECTIVE: Socioeconomic status (SES) has previously been implicated in the pain experience. The present manuscript aims to present a potential social-biological link between SES and pain via accelerated epigenetic aging.

Socioeconomic risk factors for long-term opioid use: A national registry-linkage study

BACKGROUND

Opioid use has increased substantially as a treatment for chronic pain, although harms from long-term opioid therapy outweigh the benefits. More knowledge about factors associated with long-term opioid use is needed. We aimed to investigate the association between socioeconomic status and long-term opioid use in the period 2010-2019.

METHODS

This was a nested case-control study in which the cases were all persons ≥18 years with long-term opioid use, that is use of opioids for more than 3 months (N = 215,642). Cases were matched on gender, age and index year (first long-term use period) with four controls who filled at least one opioid prescription, but never developed long-term opioid use in the study period (N = 862,568). We performed a logistic regression analysis adjusted for relevant confounders, stratified on age groups (18-67 years and 68 years and above).

RESULTS

In the younger age group, long-term opioid use was associated with low education (adjusted odds ratio, aOR = 1.54; 95% confidence interval, CI [1.51-1.57]), low income (1.33 [1.31-1.36]), being unemployed (1.40 [1.38-1.42]) and receiving disability pension (1.36 [1.33-1.38]). Weaker associations were found for living in a single-person household or in a dense geographical area. Similar associations were found for the older age group.

CONCLUSION

We found that low socioeconomic status was associated with long-term opioid use both among people in working age and older people. These results indicate a need for social and financial support for non-pharmacological treatment of chronic pain among people with lower socioeconomic status.

SIGNIFICANCE

This study shows that people with low socioeconomic status are at higher risk of developing long-term opioid use. In the clinical setting, physicians should consider socioeconomic status when prescribing opioids for chronic pain. Non-pharmacological treatment options funded by public health services should be prioritized to those with low socioeconomic status as long-term opioid use in chronic pain patients is not recommended.

Race differences in pain and pain-related risk factors among former professional American-style football players

ABSTRACT

The burden of pain is unequal across demographic groups, with broad and persisting race differences in pain-related outcomes in the United States. Members of racial and ethnic minorities frequently report more pervasive and severe pain compared with those in the majority, with at least some disparity attributable to differences in socioeconomic status. Whether race disparities in pain-related health outcomes exist among former professional football players is unknown. We examined the association of race with pain outcomes among 3995 former professional American-style football players who self-identified as either Black or White. Black players reported more intense pain and higher levels of pain interference relative to White players, even after controlling for age, football history, comorbidities, and psychosocial factors. Race moderated associations between several biopsychosocial factors and pain; higher body mass index was associated with more pain among White but not among Black players. Fatigue and psychosocial factors were more strongly related to pain among Black players relative to White players. Collectively, the substantial social and economic advantages of working as a professional athlete did not seem to erase race-related disparities in pain. We highlight an increased burden of pain among elite Black professional football players and identify race-specific patterns of association between pain and biopsychosocial pain risk factors. These findings illuminate potential future targets of interventions that may serve to reduce persistent disparities in the experience and impact of pain.

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.

Prevalence of pain and its treatment among older adults in India: a nationally representative population-based study

ABSTRACT

There were no estimates of the prevalence of pain and its treatment in the older population of India obtained from face-to-face interviews with a nationally representative sample. We addressed this evidence gap by using data on 63,931 individuals aged 45 years and older from the 2017/2018 Longitudinal Ageing Study in India. We identified pain from an affirmative response to the question: Are you often troubled by pain? We also identified those who reported pain that limited usual activities and who received treatment for pain. We estimated age- and sex-adjusted prevalence of pain, pain limiting usual activity and treatment, and compared these estimates across states and sociodemographic groups. We used a multivariable probit model to estimate full adjusted differences in the probability of each outcome across states and sociodemographic groups. We estimated that 36.6% (95% confidence interval [CI]: 35.3-37.8) of older adults in India were often troubled by pain and 25.2% (95% CI: 24.2-26.1) experienced pain limiting usual activity. We estimated that 73.3% (95% CI: 71.9-74.6) of those often troubled by pain and 76.4% (95% CI: 74.9-78.0) of those with pain that limited usual activity received treatment. There was large variation in each outcome across states. Fully adjusted prevalence of pain and pain limiting usual activity were higher among individuals who were female, older, less educated, rural residents, and poorer. Prevalence of treatment among those troubled by pain was lower among socially disadvantaged groups.

COVID-19 infection and pain in adolescents with sickle cell disease: A case series

Adolescents with sickle cell disease (SCD) have been shown to have pain-related sequelae following COVID-19 infection. In this case series, we discuss five adolescents with SCD and SARS-CoV-2 infection who subsequently developed complex pain circumstances manifested as: (1) increased frequency of acute care visits or admissions for pain; (2) new onset chronic pain; (3) new onset neuropathic pain; (4) escalation in the complexity of pharmacologic therapies; (5) increased use of nonpharmacologic interventions. While more research is needed to fully understand the implications of COVID-19 infection on pain in adolescents with SCD, these cases suggest the presence of a complex relationship.

Intersectional identity approach to chronic pain disparities using latent class analysis

ABSTRACT

Research on intersectionality and chronic pain disparities is very limited. Intersectionality explores the interconnections between multiple aspects of identity and provides a more accurate image of disparities. This study applied a relatively novel statistical approach (ie, Latent Class Analysis) to examine chronic pain disparities with an intersectional identity approach. Cross-sectional data were analyzed using pretreatment data from the Learning About My Pain trial, a randomized comparative effectiveness study of group-based psychosocial interventions (Patient-Centered Outcomes Research Institute Contract #941, Beverly Thorn, PI; clinicaltrials.gov identifier NCT01967342) for patients receiving care for chronic pain at low-income clinics in rural and suburban Alabama. Latent Class Analysis results suggested a 5-class model. To easily identify each class, the following labels were created: older adults, younger adults, severe disparity, older Black or African American, and Working Women. The latent disparity classes varied by pretreatment chronic pain functioning. Overall, the severe disparity group had the lowest levels of functioning, and the Working Women group had the highest levels of functioning. Although younger and with higher literacy levels, the younger adults group had similar levels of pain interference and depressive symptoms to the severe disparity group (P's < 0.05). The younger adults group also had higher pain catastrophizing than the older adults group (P < 0.005). Results highlighted the importance of the interactions between the multiple factors of socioeconomic status, age, and race in the experience of chronic pain. The intersectional identity theory approach through Latent Class Analysis provided an integrated image of chronic pain disparities in a highly understudied and underserved population.

Treatment Disparities Among the Black Population and Their Influence on the Equitable Management of Chronic Pain

Introduction: Growing evidence suggests disparities in the prevalence, management, progression, and outcomes of chronic, nonmalignant pain-related conditions, especially for African American patients. Objective: The purpose of this review is to explore studied causative factors that influence the management of chronic pain among African Americans, including factors that result in disparate care that may contribute to unfavorable outcomes. Methods: This narrative review is based on available literature published on this topic published within the last 10 years. Results: Assessment of chronic pain is multifaceted, often complicated by patient medical comorbidities and a complex set of biopsychosocial/spiritual/financial and legal determinants. These complexities are further exacerbated by a patient's race, by provider bias, and by structural barriers-all intersecting and culminating in disparate outcomes. Conclusions: A comprehensive analysis is needed to identify quality improvement interventions and to mitigate major barriers contributing to disparities in the management of chronic pain in the African American population.

Depression predicts chronic pain interference in racially diverse, income-disadvantaged patients

BACKGROUND

Chronic pain is one of the most common reasons adults seek medical care in the US, with prevalence estimates ranging from 11% to 40%. Mindfulness meditation has been associated with significant improvements in pain, depression, physical and mental health, sleep, and overall quality of life. Group medical visits are increasingly common and are effective at treating myriad illnesses, including chronic pain. Integrative Medical Group Visits (IMGV) combine mindfulness techniques, evidence based integrative medicine, and medical group visits and can be used as adjuncts to medications, particularly in diverse underserved populations with limited access to non-pharmacological therapies.

OBJECTIVE AND DESIGN

The objective of the present study was to use a blended analytical approach of machine learning and regression analyses to evaluate the potential relationship between depression and chronic pain in data from a randomized clinical trial of IMGV in diverse, income disadvantaged patients suffering from chronic pain and depression.

METHODS

The analytical approach used machine learning to assess the predictive relationship between depression and pain and identify and select key mediators, which were then assessed with regression analyses. It was hypothesized that depression would predict the pain outcomes of average pain, pain severity, and pain interference.

RESULTS

Our analyses identified and characterized a predictive relationship between depression and chronic pain interference. This prediction was mediated by high perceived stress, low pain self-efficacy, and poor sleep quality, potential targets for attenuating the adverse effects of depression on functional outcomes.

CONCLUSIONS

In the context of the associated clinical trial and similar interventions, these insights may inform future treatment optimization, targeting, and application efforts in racialized, income disadvantaged populations, demographics often neglected in studies of chronic pain.

The Relationship between Cognitive and Emotional Factors and Healthcare and Medication Use in People Experiencing Pain: A Systematic Review

Pain conditions are among the leading causes of global disability, impacting on global healthcare utilization (HCU). Health seeking behavior might be influenced by cognitive and emotional factors (CEF), which can be tackled by specific therapies. The purpose of this study was to systematically review the evidence concerning associations between CEF and HCU in people experiencing pain. Three databases were consulted: PubMed, Web of Science and EconLit. Risk of bias was assessed using the Downs and Black Checklist (modified). A total of 90 publications (total sample n = 59,719) was included after double-blind screening. In people experiencing pain, positive associations between general anxiety symptoms, depressive symptoms and catastrophizing and pain medication use were found. Additionally, there appears to be a relationship between general anxiety and depressive symptoms and opioid use. Symptom-related anxiety and psychological distress were found to be positively related with consulting behavior. Last, a positive association between use of complementary and alternative medicine and level of perceived symptom control was confirmed in people with pain. For other relationships no evidence or inconsistent findings were found, or they were insufficiently studied to draw firm conclusions, indicating that more research on this topic is needed.

Pain in low-income older women with disabilities: a qualitative descriptive study

The purpose of this qualitative study was to identify how low-income older women with disabilities perceive pain, pain management, and communication with healthcare providers. We interviewed 26 low-income women (average age 75 years; SD 7.0), eliciting the following overarching themes: "Invisibility of Pain: Unnoticed or Undetected," "Escalating Pain Leads to Help Seeking," "Communication with Healthcare Providers and Outcomes," "Pain Management Facilitates Function and Accomplishment," and "The Intersection of Pain, Disability, and Depressive Symptoms." Study findings support the ways in which behavior changes from pain can impede pain management.

The Association Between Symptoms of Depression and Office Visits in Patients With Nontraumatic Upper-Extremity Illness

PURPOSE

Because psychological and social factors increase symptoms and limitations, it is possible that they are also related to higher use of care.

METHODS

We used a database of an academic outpatient orthopedic department in which patient-reported outcome measures were routinely collected and identified 3,620 patients with de Quervain tendinopathy, ganglion, trapeziometacarpal arthritis, trigger digit, or carpal tunnel syndrome who remained in care at least 3 months. At every office visit, patients completed the Patient-Reported Outcomes Measurement Information System (PROMIS) Physical Function Computerized Adaptive Test (CAT), PROMIS Pain Interference CAT, and PROMIS Depression CAT. We conducted multivariable Poisson regression analysis of factors associated with the total number of office visits, accounting for PROMIS scores at the first office visit, age, surgical treatment, sex, diagnosis, and clinician team.

RESULTS

Operative treatment had the greatest influence on the number of office visits. Other variables associated with the number of visits were female sex, younger age, higher PROMIS Depression scores, and higher Pain Interference scores.

CONCLUSIONS

Treatment choice had the greatest influence on the number of subsequent visits for atraumatic conditions. The fact that the total number of office visits is associated with greater symptoms of depression and greater pain interference, independent of treatment choice, suggests a relation between mental health and resource use.

CLINICAL RELEVANCE

Quality improvement efforts and future research might address whether adding strategies to decrease symptoms of depression and optimize coping strategies (to reduce pain interference) might improve upper-extremity health more efficiently than standard treatment alone.
