The Unique and Interactive Effects of Patient Race, Patient Socioeconomic Status, and Provider Attitudes on Chronic Pain Care Decisions

Exercise and Dietary Recommendations for Women with Chronic Pain: What's Weight and Race Got To Do with It?

Exercise and diet are beneficial for pain, yet many patients do not receive such recommendations from providers. This may be due to biases related to gender, race, and weight. We recruited medical students (N = 90) to view videos of women with chronic back pain performing a functional task; patients varied by weight (overweight/obese) and race (Black/White). For each woman patient, providers rated their likelihood of recommending exercises or dietary changes. Ratings significantly differed across recommendations (F(2.75, 244.72) = 6.19, P < .01) in that providers were more likely to recommend flexibility exercises than aerobic exercises and dietary changes and were more likely to recommend strength exercises than dietary changes. Results also indicated that women with obesity were more likely to receive aerobic (F(1,89) = 17.20, P < .01), strength (F(1,89) = 6.08, P = .02), and dietary recommendations (F(1,89) = 37.56, P < .01) than were women with overweight. Additionally, White women were more likely to receive a recommendation for flexibility exercises (F(1,89) = 4.92, P = .03) than Black women. Collectively, these findings suggest that providers' exercise and dietary recommendations for women with chronic pain are influenced by the weight status and racial identity of the patient. Future studies are needed to identify the reasons underlying these systematic differences, including the stereotypes and attitudes that may be driving these effects. PERSPECTIVE: This article presents results on how patient weight and race impact providers' exercise and diet recommendations for women with chronic back pain. Provider recommendations for these modalities may be systematically biased in a way that impedes care and impacts patient functioning.

Evaluation of the psychometric properties of the health care providers' pain and impairment relationship scale (HC-PAIRS) in health professionals and university students from Chile and Colombia

Background

Chronic back pain is a frequent and disabling health problem. There is evidence that ignorance and erroneous beliefs about chronic low back pain among health professionals interfere in the treatment of people who suffer from it. The Health Care Providers' Pain and Impairment Relationship Scale (HC-PAIRS) has been one of the most used scale to assess these misbeliefs, but no studies have been reported in Latin America. Method: We studied the factorial structure of the HC-PAIRS in health personnel and health sciences university students in two Latin American countries: Colombia (n = 930) and Chile (n = 190). Spain's data was taken of the original study of the Spanish version of the HC-PAIRS (171 Physiotherapy students). Additionally, the measurement invariance of this scale among Chile, Colombia and Spain was evaluated by calculating three nested models: configural, metric and scalar. We used a Confirmatory Factor Analysis (CFA) in both Latin American samples, with Maximum Likelihood Robust (MLR) estimation to estimate the parameters. For the final model in each sample, reliability was assessed with the Composite Reliability (CR) index, and to obtain the proportion of variance explained by the scale the Average Variance Extracted (AVE) was calculated.

Results

The one-factor solution shows an acceptable fit in both countries after deleting items 1, 6, and 14. For the resulting scale, the CR value is adequate, but the AVE is low. There is scalar invariance between Chile and Colombia, but not between these two countries and Spain.

Conclusions

HC-PAIRS is useful for detecting misconceptions about the relationship between chronic low back pain that would cause health personnel to give wrong recommendations to patients. However, it has psychometric weaknesses, and it is advisable to obtain other evidence of validity.

Assessing pain in older people with normal, mildly impaired or severely impaired cognition

Pain is a relatively common experience among older people, but unrelieved pain has significant functional, cognitive and emotional consequences for this population. A comprehensive and accurate pain assessment is essential for effective pain management. Self-report tools are suitable to assess pain in older people with normal or mildly impaired cognition, while observational tools are suitable for use with those with significant cognitive impairment or communication difficulties. However, pain assessment in older people can be challenging. The use of one tool on its own is rarely sufficient and it is crucial to involve family carers in assessment of pain in older people with severe cognitive impairment. This article discusses different tools and strategies, including the benefits and limitations, for assessing pain in older people.

Health professionals implicit bias of patients with low socioeconomic status (SES) and its effects on clinical decision-making: a scoping review

OBJECTIVES

Research indicates that people with lower socioeconomic status (SES) receive inferior healthcare and experience poorer health outcomes compared with those with higher SES, in part due to health professional (HP) bias. We conducted a scoping review of the impact of HP bias about SES on clinical decision-making and its effect on the care of adults with lower SES.

DESIGN

JBI scoping review methods were used to perform a systematic comprehensive search for literature. The scoping review protocol has been published in BMJ Open.

DATA SOURCES

Medline, Embase, ASSIA, Scopus and CINAHL were searched, from the first available start date of the individual database to March 2023. Two independent reviewers filtered and screened papers.

ELIGIBILITY CRITERIA

Studies of all designs were included in this review to provide a comprehensive map of the existing evidence of the impact of HP bias of SES on clinical decision-making and its effect on the care for people with lower SES.

DATA EXTRACTION AND SYNTHESIS

Data were gathered using an adapted JBI data extraction tool for systematic scoping reviews.

RESULTS

Sixty-seven papers were included from 1975 to 2023. 35 (73%) of the included primary research studies reported an association between HP SES bias and decision-making. Thirteen (27%) of the included primary research studies did not find an association between HP SES bias and decision-making. Stereotyping and bias can adversely affect decision-making when the HP is fatigued or has a high cognitive load. There is evidence of intersectionality which can have a powerful cumulative effect on HP assessment and subsequent decision-making. HP implicit bias may be mitigated through the assertiveness of the patient with low SES.

CONCLUSION

HP decision-making is at times influenced by non-medical factors for people of low SES, and assumptions are made based on implicit bias and stereotyping, which compound or exacerbate health inequalities. Research that focuses on decision-making when the HP has a high cognitive load, would help the health community to better understand this potential influence.

The Impact of Patient Race, Patient Socioeconomic Status, and Cognitive Load of Physician Residents and Fellows on Chronic Pain Care Decisions

Social stereotypes are more likely to influence decision-making under conditions of high cognitive load (ie, mental workload), such as in medical settings. We examined how patient race, patient socioeconomic status (SES), physician cognitive load, and physician implicit beliefs about race and SES differences in pain tolerance impacted physicians' pain treatment decisions. Physician residents and fellows (N = 120) made treatment decisions for 12 computer-simulated patients with back pain that varied by race (Black/White) and SES (low/high). Half of the physicians were randomized to be interrupted during the decision task to make hypertension medication conversion calculations (high cognitive load group), while the other half completed the task without interruptions (low cognitive load group). Both groups were given equal time to make pain care decisions (2.5 minutes/patient). Results of multilevel ordinal logistic regression analyses indicated that physicians prescribed weaker analgesics to patients with high vs. low SES (odds ratio = .68, 95% confidence interval [.48, .97], P = .03). There was also a patient SES-by-cognitive load interaction (odds ratio = .56, 95% confidence interval [.31, 1.01], P = .05) that is theoretically and potentially practically meaningful but was not statistically significant at P < .05. These findings shed light on physician cognitive load as a clinically-relevant factor in the context of pain care quality and equity. PERSPECTIVE: These findings highlight the clinical relevance of physician cognitive load (eg, mental workload) when providing pain care for diverse patients. This line of work can support the development of interventions to manage physician cognitive load and its impact on pain care, which may ultimately help reduce pain disparities.

Fairness gaps in Machine learning models for hospitalization and emergency department visit risk prediction in home healthcare patients with heart failure

OBJECTIVES

This study aims to evaluate the fairness performance metrics of Machine Learning (ML) models to predict hospitalization and emergency department (ED) visits in heart failure patients receiving home healthcare. We analyze biases, assess performance disparities, and propose solutions to improve model performance in diverse subpopulations.

METHODS

The study used a dataset of 12,189 episodes of home healthcare collected between 2015 and 2017, including structured (e.g., standard assessment tool) and unstructured data (i.e., clinical notes). ML risk prediction models, including Light Gradient-boosting model (LightGBM) and AutoGluon, were developed using demographic information, vital signs, comorbidities, service utilization data, and the area deprivation index (ADI) associated with the patient's home address. Fairness metrics, such as Equal Opportunity, Predictive Equality, Predictive Parity, and Statistical Parity, were calculated to evaluate model performance across subpopulations.

RESULTS

Our study revealed significant disparities in model performance across diverse demographic subgroups. For example, the Hispanic, Male, High-ADI subgroup excelled in terms of Equal Opportunity with a metric value of 0.825, which was 28% higher than the lowest-performing Other, Female, Low-ADI subgroup, which scored 0.644. In Predictive Parity, the gap between the highest and lowest-performing groups was 29%, and in Statistical Parity, the gap reached 69%. In Predictive Equality, the difference was 45%.

DISCUSSION AND CONCLUSION

The findings highlight substantial differences in fairness metrics across diverse patient subpopulations in ML risk prediction models for heart failure patients receiving home healthcare services. Ongoing monitoring and improvement of fairness metrics are essential to mitigate biases.

Social Determinants and Consequences of Pain: Toward Multilevel, Intersectional, and Life Course Perspectives

Despite wide endorsement of a biopsychosocial framework for pain, social aspects of pain remain rarely addressed in the context of pain prevention and management. In this review, we aim to 1) examine the broad scope of social determinants and consequences of pain and their interactions across multiple levels of organization, and 2) provide a framework synthesizing existing concepts and potential areas for future work on social aspects of pain, drawing upon socioecological, intersectional, and life course approaches. Integrating interdisciplinary theory and evidence, we outline pathways through which multilevel social factors and pain may affect each other over time. We also provide a brief summary of intrapersonal aspects of pain, which are thought to operate at the interface between individuals and the social context. Progressing from micro- to macrolevel factors, we illustrate how social determinants of pain can directly or indirectly contribute to pain experiences, expression, risk, prognosis, and impact across populations. We consider 1) at the interpersonal level, the roles of social comparison, social relatedness, social support, social exclusion, empathy, and interpersonal conflict; 2) at the group or community level, the roles of intimacy groups, task groups, social categories, and loose associations; and 3) at the societal level, the roles of political, economic, and cultural systems, as well as their policies and practices. We present examples of multilevel consequences of pain across these levels and discuss opportunities to reduce the burden and inequities of pain by expanding multilevel social approaches in pain research and practice. PERSPECTIVE: Despite wide endorsement of a biopsychosocial framework for pain, social aspects of pain are often unclearly defined, hindering their use in pain prevention, management, and research. We summarize the scope of social aspects of pain and provide a framework synthesizing existing concepts and potential areas for future work.

Social Class and Social Pain: Target SES Biases Judgments of Pain and Support for White Target Individuals

Social pain, defined as distress caused by negative interpersonal experiences (e.g., ostracism, mistreatment), is detrimental to health. Yet, it is unclear how social class might shape judgments of the social pains of low-socioeconomic status (SES) and high-SES individuals. Five studies tested competing toughness and empathy predictions for SES's effect on social pain judgments. Consistent with an empathy account, in all studies (Ncumulative = 1,046), low-SES White targets were judged more sensitive to social pain than high-SES White targets. Further, empathy mediated these effects, such that participants felt greater empathy and expected more social pain for low-SES targets relative to high-SES targets. Social pain judgments also informed judgments of social support needs, as low-SES targets were presumed to need more coping resources to manage hurtful events than high-SES targets. The current findings provide initial evidence that empathic concern for low-SES White individuals sensitizes social pain judgments and increases expected support needs for lower class White individuals.

Racial Differences in Movement-Related Appraisals and Pain Behaviors Among Adults With Chronic Low Back Pain

Research documents racial disparities in chronic low back pain (CLBP). Few studies have examined racial disparities in movement-related appraisals and no studies have examined anticipatory appraisals prior to or pain behaviors during functional activities among individuals with CLBP. This cross-sectional study examined racial differences in anticipatory appraisals of pain, concerns about harm, and anxiety, appraisals of pain and anxiety during movement, and observed pain behaviors during 3 activities of daily living (supine-to-standing bed task, sitting-to-standing chair task, floor-to-waist lifting task) in a sample (N = 126) of non-Hispanic Black (31.0%), Hispanic (30.2%), and non-Hispanic White (38.9%) individuals with CLBP. Hispanic participants reported more expected pain, concerns about harm, and pre-movement anxiety prior to the bed and chair tasks compared to non-Hispanic White participants. Hispanic participants reported more pain during the bed task and more anxiety during the bed and chair tasks compared to non-Hispanic White participants. Non-Hispanic Black participants reported more expected pain, concerns about harm, and pre-movement anxiety prior to the bed task and more pre-movement anxiety prior to the chair task compared to non-Hispanic White participants. Non-Hispanic Black participants reported more anxiety during the bed and chair tasks compared to non-Hispanic White participants. Non-Hispanic Black participants were observed to have significantly more verbalizations of pain during the bed task compared to non-Hispanic White participants. Current findings identify racial disparities in important cognitive-behavioral and fear-avoidance mechanisms of pain. Results indicate a need to revisit traditional theoretical and treatment models in CLBP, ensuring racial disparities in pain cognitions are considered. PERSPECTIVE: This study examined racial disparities in anticipatory and movement-related appraisals, and pain behaviors during activities of daily living among Non-Hispanic Black, Non-Hispanic White, and Hispanic individuals with CLBP. Racial disparities identified in the current study have potentially important theoretical implications surrounding cognitive-behavioral and fear-avoidance mechanisms of pain.

Telehealth delivery of physical therapist-led interventions for persons with chronic low back pain in underserved communities: lessons from pragmatic clinical trials

In this perspective, we present our experience developing and conducting two pragmatic clinical trials investigating physical therapist-led telehealth strategies for persons with chronic low back pain. Both trials, the BeatPain Utah and AIM-Back trials, are part of pragmatic clinical trial collaboratories and are being conducted with persons from communities that experience pain management disparities. Practice guidelines recommend nonpharmacologic care, and advise against opioid therapy, for the primary care management of persons with chronic low back pain. Gaps between these recommendations and actual practice patterns are pervasive, particularly for persons from racial or ethnic minoritized communities, those with fewer economic resources, and those living in rural areas including Veterans. Access barriers to evidence-based nonpharmacologic care, which is often provided by physical therapists, have contributed to these evidence-practice gaps. Telehealth delivery has created new opportunities to overcome access barriers for nonpharmacologic pain care. As a relatively new delivery mode however, telehealth delivery of physical therapy comes with additional challenges related to technology, intervention adaptations and cultural competence. The purpose of this article is to describe the challenges encountered when implementing telehealth physical therapy programs for persons with chronic low back pain in historically underserved communities. We also discuss strategies developed to overcome barriers in an effort to improve access to telehealth physical therapy and reduce pain management disparities. Inclusion of diverse and under-represented communities in pragmatic clinical trials is a critical consideration for improving disparities, but the unique circumstances present in these communities must be considered when developing implementation strategies.

Use of implementation mapping in the planning of a hybrid type 1 pragmatic clinical trial: the BeatPain Utah study

BACKGROUND

Considerable disparities in chronic pain management have been identified. Persons in rural, lower income, and minoritized communities are less likely to receive evidence-based, nonpharmacologic care. Telehealth delivery of nonpharmacologic, evidence-based interventions for persons with chronic pain is a promising strategy to lessen disparities, but implementation comes with many challenges. The BeatPain Utah study is a hybrid type 1 effectiveness-implementation pragmatic clinical trial investigating telehealth strategies to provide nonpharmacologic care from physical therapists to persons with chronic back pain receiving care in ommunity health centers (CHCs). CHCs provide primary care to all persons regardless of ability to pay. This paper outlines the use of implementation mapping to develop a multifaceted implementation plan for the BeatPain study.

METHODS

During a planning year for the BeatPain trial, we developed a comprehensive logic model including the five-step implementation mapping process informed by additional frameworks and theories. The five iterative implementation mapping steps were addressed in the planning year: (1) conduct needs assessments for involved groups; (2) identify implementation outcomes, performance objectives, and determinants; (3) select implementation strategies; (4) produce implementation protocols and materials; and (5) evaluate implementation outcomes.

RESULTS

CHC leadership/providers, patients, and physical therapists were identified as involved groups. Barriers and assets were identified across groups which informed identification of performance objectives necessary to implement two key processes: (1) electronic referral of patients with back pain in CHC clinics to the BeatPain team and (2) connecting patients with physical therapists providing telehealth. Determinants of the performance objectives for each group informed our choice of implementation strategies which focused on training, education, clinician support, and tailoring physical therapy interventions for telehealth delivery and cultural competency. We selected implementation outcomes for the BeatPain trial to evaluate the success of our implementation strategies.

CONCLUSIONS

Implementation mapping provided a comprehensive and systematic approach to develop an implementation plan during the planning phase for our ongoing hybrid effectiveness-implementation trial. We will be able to evaluate the implementation strategies used in the BeatPain Utah study to inform future efforts to implement telehealth delivery of evidence-based pain care in CHCs and other settings.

Managing Chronic Pain in Cancer Survivorship: Communication Challenges and Opportunities as Described by Cancer Survivors

OBJECTIVES

Many cancer survivors experience chronic pain after completing curative-intent treatment. Based on available data, chronic pain may be undertreated in this context; however, little is known about cancer survivors' experiences with clinical management of chronic pain. The purpose of this study was to better understand cancer survivors' pain management experiences after curative-intent treatment.

METHODS

We conducted 13 semi-structured interviews with a convenience sample of cancer survivors who had completed treatment for stage I-III breast, head/neck, lung or colorectal cancer. We used a thematic approach to qualitative data analysis.

RESULTS

Participants described that chronic pain often goes unrecognized by their providers, potentially due to limitations in how pain is assessed clinically and the tendency of both cancer survivors and providers to minimize or invalidate the pain experience. To improve communication, participants suggested that providers ask more open-ended questions about their pain, help them to establish functional goals, and provide patients with options for pain management.

SIGNIFICANCE OF RESULTS

This study demonstrates the importance of provider-initiated communication around pain management for cancer survivors to make them feel more supported in their care. Communication and shared decision-making interventions may improve cancer survivor-provider communication around chronic pain management, addressing an important gap in survivorship care.

A review of mental health disparities during COVID-19: Evidence, mechanisms, and policy recommendations for promoting societal resilience

Social and economic inequality are chronic stressors that continually erode the mental and physical health of marginalized groups, undermining overall societal resilience. In this comprehensive review, we synthesize evidence of greater increases in mental health symptoms during the COVID-19 pandemic among socially or economically marginalized groups in the United States, including (a) people who are low income or experiencing homelessness, (b) racial and ethnic minorities, (c) women and lesbian, gay, bisexual, transgender, queer, and questioning (LGBTQ+) communities, (d) immigrants and migrants, (e) children and people with a history of childhood adversity, and (f) the socially isolated and lonely. Based on this evidence, we propose that reducing social and economic inequality would promote population mental health and societal resilience to future crises. Specifically, we propose concrete, actionable recommendations for policy, intervention, and practice that would bolster five "pillars" of societal resilience: (1) economic safety and equity, (2) accessible healthcare, including mental health services, (3) combating racial injustice and promoting respect for diversity, equity, and inclusion, (4) child and family protection services, and (5) social cohesion. Although the recent pandemic exposed and accentuated steep inequalities within our society, efforts to rebuild offer the opportunity to re-envision societal resilience and policy to reduce multiple forms of inequality for our collective benefit.

Unconscious Bias among Health Professionals: A Scoping Review

BACKGROUND

Unconscious biases are one of the causes of health disparities. Health professionals have prejudices against patients due to their race, gender, or other factors without their conscious knowledge. This review aimed to provide an overview of research on unconscious bias among health professionals and to investigate the biases that exist in different regions of the world, the health professions that are considered, and the research gaps that still exist.

METHODS

We conducted a scoping review by systematically searching PubMed/MEDLINE, CINAHL, PsycINFO, PsycARTICLES, and AMED. All records were double-screened and included if they were published between 2011 and 2021.

RESULTS

A total of 5186 records were found. After removing duplicates (n = 300), screening titles and abstracts (n = 4210), and full-text screening (n = 695), 87 articles from 81 studies remained. Studies originated from North America (n = 60), Europe (n = 13), and the rest of the world (n = 6), and two studies were of global scope. Racial bias was investigated most frequently (n = 46), followed by gender bias (n = 11), weight bias (n = 10), socio-economic status bias (n = 9), and mental illness bias (n = 7). Most of the studies were conducted by physicians (n = 51) and nurses (n = 20). Other health care professionals were rarely included in these studies.

CONCLUSIONS

Most studies show that health professionals have an implicit bias. Racial biases among physicians and nurses in the USA are well confirmed. Research is missing on other biases from other regions and other health professions.

Addressing chronic pain disparities between Black and White people: a narrative review of socio-ecological determinants

A 2019 review article modified the socio-ecological model to contextualize pain disparities among different ethnoracial groups; however, the broad scope of this 2019 review necessitates deeper socio-ecological inspection of pain within each ethnoracial group. In this narrative review, we expanded upon this 2019 article by adopting inclusion criteria that would capture a more nuanced spectrum of socio-ecological findings on chronic pain within the Black community. Our search yielded a large, rich body of literature composed of 174 articles that shed further socio-ecological light on how chronic pain within the Black community is influenced by implicit bias among providers, psychological and physical comorbidities, experiences of societal and institutional racism and biomedical distrust, and the interplay among these factors. Moving forward, research and public-policy development must carefully take into account these socio-ecological factors before scaling up pre-existing solutions with questionable benefit for the chronic pain needs of Black individuals.

Pain management: A deeper look at rural and urban nurses' perceptions and experiences

PURPOSE

About 11.4 million individuals admitted to misusing an opioid in the past year. The purpose of this study was to determine if nurses' definitions of pain management differed by location, and to assess the challenges treating patients with pain management concerns. This study fills a gap by comparing quantitative and qualitative feedback from nurses on pain management concerns in their practice location.

METHODS

Data were collected using an electronic survey emailed to licensed nurses across the United States. The mixed methods survey used multiple choice, select all that apply, and open-ended responses to gather data on nurses' perceptions of pain management. One hundred and eighty nurses completed the survey and were included in the study. Sixty-six percent practiced in an urban hospital.

FINDINGS

Rural and urban nurses defined pain management as nonopioids and opioids. Seventy-one percent of urban nurses defined pain management as physical therapy compared to only 61% of rural nurses. Similarly, 62% of urban nurses identified homeopathic medicines and treatments as pain management techniques compared to 52% of rural nurses. From the qualitative data, 32% of rural nurses stated that patients with pain management concerns only want pain medications compared to 14% of urban nurses.

CONCLUSIONS

Nurses have a critical position in and valuable perspective on the opioid epidemic. Rural communities are relatively disadvantaged in combatting the opioid epidemic. The finding that rural residents only want pain medication instead of alternative pain management options further challenges the country's rural health care workforce.

The Experience of BIPOC Living with Chronic Pain in the USA: Biopsychosocial Factors that Underlie Racial Disparities in Pain Outcomes, Comorbidities, Inequities, and Barriers to Treatment

PURPOSE OF REVIEW

This review synthesizes recent findings related to the biopsychosocial processes that underlie racial disparities in chronic pain, while highlighting opportunities for interventions to reduce disparities in pain treatment among BIPOC.

RECENT FINDINGS

Chronic pain is a prevalent and costly public health concern that disproportionately burdens Black, Indigenous, and people of color (BIPOC). This unequal burden arises from an interplay among biological, psychological, and social factors. Social determinants of health (e.g., income, education level, and lack of access or inability to utilize healthcare services) are known to affect overall health, including chronic pain, and disproportionately affect BIPOC communities. This burden is exacerbated by exposure to psychosocial stressors (i.e., perceived injustice, discrimination, and race-based traumatic stress) and can affect biological systems that modulate pain (i.e., inflammation and pain epigenetics). Further, there are racial/ethnic disparities in pain treatment, perpetuating the cycle of undermanaged chronic pain among BIPOC.

Relationship Between Socioeconomic Status and the Outcome of Lumbar Epidural Steroid Injections for Lumbar Radiculopathy

OBJECTIVE

The aim of the study was to investigate the relationship between socioeconomic status and pain reduction from epidural steroid injections for lumbar radiculopathy.

METHODS

The retrospective cohort consisted of patients undergoing epidural steroid injection for lumbar radiculopathy ( n = 544). Numeric Pain Rating Scale was measured at baseline and 2 wks after epidural steroid injection. Socioeconomic status was estimated using median family income in patients' ZIP code. Linear and mixed models examined demographic and clinical differences in pain before and after injection and whether family income moderated the effect.

RESULTS

Majority of patients were White (72.4%), female (56.4%), engaged in physical activity (68.2%), and underwent unilateral, transforaminal epidural steroid injection (86.0% and 92.1%, respectively). Non-White patients and those who did not engage in physical activity had higher baseline pain ( P < 0.05). Lower socioeconomic status was associated with higher baseline pain (β = 0.06 per $10,000, P = 0.01). Patients with lower socioeconomic status experienced larger improvement in pain after epidural steroid injection: -1.56 units for patients in the 10th percentile of family income versus -0.81 for 90th percentile. Being a current smoker was associated with higher pain (β = 0.76, P = 0.03) and engaging in structured physical activity with less pain (β = -0.07 P < 0.01).

CONCLUSIONS

Lower socioeconomic status was independently associated with higher pain alleviation after controlling for other potentially influential demographics. Modifiable lifestyle factors may be a target of potential intervention.

Health professional's implicit bias of adult patients with low socioeconomic status (SES) and its effects on clinical decision-making: a scoping review protocol

INTRODUCTION

Despite efforts to improve population health and reduce health inequalities, higher morbidity and mortality rates for people with lower socioeconomic status (SES) persist. People with lower SES are said to receive worse care and have worse outcomes compared with those with higher SES, in part due to bias and prejudice. Implicit biases adversely affect professional patient relationships and influence healthcare-related decision-making. A better understanding of the relationship between SES and healthcare-related decision-making is therefore essential to address socioeconomic inequalities in health.

AIM

To scope the reported impact of health professionals bias about SES on clinical decision-making and its effect on the care of adults with lower SES in wider literature.

METHODS

This scoping review will use Joanna Briggs Institute methods and will report its findings in line with Preferred Items for Systematic Reviews and Meta-Analyses for Protocols and Scoping Reviews guidelines. Data analysis, interpretation and reporting will be underpinned by the PAGER (Patterns, Advances, Gaps, Evidence for Practice and Research recommendations) framework and input from a patient and public interest representative. A systematic search for literature will be conducted on various, pertinent databases to identify relevant literature such as peer-reviewed articles, editorials, discussion papers and empirical research papers. Additionally, other sources of relevant literature such as policies, guidelines, reports and conference abstracts, identified through key website searches will be considered for inclusion.

ETHICS AND DISSEMINATION

Ethical approval is not required for this scoping review. The results will be disseminated through an open access peer-reviewed international journal, conference presentations and a plain language summary that will be shared with the public and other relevant stakeholders.

Primary Care Physicians' Learning Needs in Returning Ill or Injured Workers to Work. A Scoping Review

Primary care physicians are uniquely positioned to assist ill and injured workers to stay-at-work or to return-to-work. Purpose The purpose of this scoping review is to identify primary care physicians' learning needs in returning ill or injured workers to work and to identify gaps to guide future research. Methods We used established methodologies developed by Arksey and O'Malley, Cochrane and adapted by the Systematic Review Program at the Institute for Work & Health. We used Distiller SR©, an online systematic review software to screen for relevance and perform data extraction. We followed the PRISMA for Scoping Reviews checklist for reporting. Results We screened 2106 titles and abstracts, 375 full-text papers for relevance and included 44 studies for qualitative synthesis. The first learning need was related to administrative tasks. These included (1) appropriate record-keeping, (2) time management to review occupational information, (3) communication skills to provide clear, sufficient and relevant factual information, (4) coordination of services between different stakeholders, and (5) collaboration within teams and between different professions. The second learning need was related to attitudes and beliefs and included intrinsic biases, self-confidence, role clarity and culture of blaming the patient. The third learning need was related to specific knowledge and included work capacity assessments and needs for sick leave, environmental exposures, disclosure of information, prognosis of certain conditions and care to certain groups such as adolescents and pregnant workers. The fourth learning need was related to awareness of services and tools. Conclusions There are many opportunities to improve medical education for physicians in training or in continuing medical education to improve care for workers with an illness or injury that affect their work.

Ethnocultural Minority Workers and Sustainable Return to Work Following Work Disability: A Qualitative Interpretive Description Study

Purpose This article provides a state-of-the-art review of issues and factors associated with the sustainable return to work (S-RTW) of ethnocultural minority workers experiencing disability situations attributable to one of four major causes: musculoskeletal disorders, common mental disorders, other chronic diseases or cancer. Methods Using an interpretive description method, an integrative review was conducted of the literature on ethnocultural factors influencing S-RTW issues and factors associated with these four major work-disability causes. An initial review of the 2006-2016 literature was subsequently updated for November 2016-May 2021. To explore and contextualize the results, four focus groups were held with RTW stakeholders representing workplaces, insurers, the healthcare system and workers. Qualitative thematic analysis was performed. Results A total of 56 articles were analyzed and 35 stakeholders participated in four focus groups. Two main findings emerged. First, belonging to an ethnocultural minority group appears associated with cumulative risk factors that may contribute to vulnerability situations and compound the complexity of S-RTW. Second, cultural differences with respect to the prevailing host-country culture may generate communication and trust issues, and conflicts in values and representations, in turn possibly hindering the establishment of positive relationships among all stakeholders and the ability to meet workers' needs. Being a woman in these groups and/or having a lower level of integration into the host country's culture also appear associated with greater S-RTW challenges. Conclusions Based on our findings, we recommend several possible strategies, such as the cultural humility model, for preventing differences from exacerbating the already significant vulnerability situation of some ethnocultural minority workers.

UK healthcare services for people with fibromyalgia: results from two web-based national surveys (the PACFiND study)

Background

The UK’s “Getting It Right First Time” programme recommends that management of people with fibromyalgia should centre on primary care. However, it remains unclear as to how best to organise health systems to deliver services to optimise patient outcomes.

Aim

To profile UK healthcare services for people with fibromyalgia: provision of National Health Services (NHS) and use of non-NHS services by people with fibromyalgia.

Methods

Two online open surveys (A and B) incorporating questions about diagnosis, treatment and management of fibromyalgia and gaps in healthcare services were conducted between 11th September 2019 and 3rd February 2020. These were targeted to NHS healthcare professionals consulting with people with fibromyalgia (Survey A) and people ≥16 years diagnosed with fibromyalgia using non-NHS services to manage their condition (Survey B). Descriptive statistics were used to report quantitative data. Thematic analysis was undertaken for qualitative data.

Results

Survey A received 1701 responses from NHS healthcare professionals across the UK. Survey B received 549 responses from people with fibromyalgia. The results show that NHS services for people with fibromyalgia are highly disparate, with few professionals reporting care pathways in their localities. Diagnosing fibromyalgia is variable among NHS healthcare professionals and education and pharmacotherapy are mainstays of NHS treatment and management. The greatest perceived unmet need in healthcare for people with fibromyalgia is a lack of available services. From the pooled qualitative data, three themes were developed: ‘a troublesome label’, ‘a heavy burden’ and ‘a low priority’. Through the concept of candidacy, these themes provide insight into limited access to healthcare for people with fibromyalgia in the UK.

Conclusion

This study highlights problems across the NHS in service provision and access for people with fibromyalgia, including several issues less commonly discussed; potential bias towards people with self-diagnosed fibromyalgia, challenges facing general practitioners seeking involvement of secondary care services for people with fibromyalgia, and a lack of mental health and multidisciplinary holistic services to support those affected. The need for new models of primary and community care that offer timely diagnosis, interventions to support self-management with access to specialist services if needed, is paramount.

Development of a low resource exercise rehabilitation application for musculoskeletal disorders to help underserved patients in a primary care setting

OBJECTIVE

We set out to create a Family Medicine EHR (electronic health record) embedded exercise application. This was done to evaluate the utility of the exercise app for providers and to understand the usefulness of the exercise app from the perspective of patients.

METHODS

This exercise application was developed through an iterative process with repeated pre-testing and feedback from an interprofessional team and embedded into the EHR at an academic family medicine clinic. Anecdotal feedback from patients was used to inform pre-testing adaptations.

RESULTS

The application required six iterations prior to clinical utility. It had several features that clinicians and patients felt were beneficial. These features involved a customizable exercise directory with pre-made templated plans which could be further modified. To overcome accessibility barriers, the application was developed to include digital and printable copies with an integrated direct email option for ease of remote sharing with patients.

CONCLUSION

A customizable, open-source exercise application was developed to facilitate provider exercise prescription and support patient self-management. This project may be useful for other providers interested in developing similar programs to address musculoskeletal conditions in their patients. Next steps are to undertake pilot testing of the app with broader provider and patient feedback.

Over-rating pain is overrated: A fundamental self-other bias in pain reporting behavior

Wide-spread cultural beliefs influence personal experiences and clinical treatment of pain, yet are often unexamined and unchallenged in the pain literature. The common cultural belief that people generally over-report or exaggerate pain is familiar, reflected in discordant patient-provider pain assessments, and compounded in the context of disparities in pain treatment. However, no studies have directly measured the prevalence of this belief among the general population, nor challenged the validity of this assumption by assessing normative pain reporting in clinical settings. Results of an initial and replication study suggest that reporting pain accurately "as-is" is the norm, yet most people still believe that others normatively over-report pain. We refer to the phenomenon by which most people report their pain as they experience it while paradoxically believing that others over-report their pain as the fundamental pain bias, and suggest this false perception may contribute to larger scale pain stigma and poor outcomes for people in pain. We also identify counter-stereotypical patterns of pain reporting among groups (i.e., women, Latinx Americans) that face more disparate care. Results reinforce the need for respecting patient pain reports, and suggest that distrust surrounding others' pain experiences is prevalent in society.

Opioid-related risk perceptions in chronic pain: influence of patient gender and previous misuse behaviors

ABSTRACT

Little is known about the factors that influence providers' perceptions of patient risk for aberrant opioid use. Patient gender may interact with previous opioid misuse to influence these perceptions. We asked 131 physicians to view videos and vignettes for 8 virtual patients with chronic pain. Gender (male/female) and previous prescription opioid misuse (present/absent) varied across patients; the vignettes were otherwise balanced on demographic and clinical characteristics. For each patient, providers assessed 4 risk domains: opioid-related adverse events, opioid misuse or abuse, opioid addiction, and opioid diversion. Results indicated a significant gender-by-misuse interaction for risk of opioid misuse orabuse. When previous misuse behaviors were absent, providers rated men at higher risk; there was no gender difference when previous misuse behaviors were present. A significant gender-by-misuse interaction was found for risk of opioid-related adverse events. Providers perceived men to be at higher risk when previous misuse behaviors were absent; there was no gender difference when previous misuse behaviors were present. A significant gender-by-misuse interaction was found for risk of opioid addiction. Providers rated women at higher risk when previous misuse behaviors were present and men at higher risk when previous misuse behaviors were absent. There were significant main effects of gender and misuse for risk of opioid diversion. Providers rated men and those with previous misuse behaviors at higher risk. These results demonstrate that patient gender and previous opioid misuse have unique and interactive effects on provider perceptions of prescription opioid-related risks. Studies are needed to identify the mechanisms underlying these effects, such as gender-based stereotypes about risk-taking and drug abuse.

The Influence of Race, Sex, and Social Disadvantage on Self-reported Health in Patients Presenting With Chronic Musculoskeletal Pain

OBJECTIVE

The aim of the study was to better address sociodemographic-related health disparities. This study examined which sociodemographic variables most strongly correlate with self-reported health in patients with chronic musculoskeletal pain.

DESIGN

This single-center, cross-sectional study examined adult patients, followed by a physiatrist for chronic (≥4 yrs) musculoskeletal pain. Sociodemographic variables considered were race, sex, and disparate social disadvantage (measured as residential address in the worst vs. best Area Deprivation Index national quartile). The primary comparison was the adjusted effect size of each variable on physical and behavioral health (measured by Patient-Reported Outcomes Measurement Information System [PROMIS]).

RESULTS

In 1193 patients (age = 56.3 ± 13.0 yrs), disparate social disadvantage was associated with worse health in all domains assessed (PROMIS Physical Function Β = -2.4 points [95% confidence interval = -3.8 to -1.0], Pain Interference = 3.3 [2.0 to 4.6], Anxiety = 4.0 [1.8 to 6.2], and Depression = 3.7 [1.7 to 5.6]). Black race was associated with greater anxiety than white race (3.2 [1.1 to 5.3]), and female sex was associated with worse physical function than male sex (-2.5 [-3.5 to -1.5]).

CONCLUSIONS

Compared with race and sex, social disadvantage is more consistently associated with worse physical and behavioral health in patients with chronic musculoskeletal pain. Investment to ameliorate disadvantage in geographically defined communities may improve health in sociodemographically at-risk populations.

Bias in Musculoskeletal Pain Management and Bias-Targeted Interventions to Improve Pain Outcomes: A Scoping Review

Bias in healthcare negatively impacts disparities in care, treatment, and outcomes, especially among minority populations. A scoping review of the literature was performed to provide a deeper understanding of how bias influences musculoskeletal pain and potential effects of bias-targeted interventions on reducing pain disparities, as well as identify gaps and make suggestions for further research in this area. Publications from peer-reviewed journals were searched using the databases PubMed/MEDLINE, PsycINFO, CINAHL, and Scopus, with 18 studies identified. The literature review revealed that clinician-based bias and discrimination worsen pain and disability by reducing access to treatment and increasing patient pain-related injustice, catastrophizing, depression, and perceived stress. In contrast, clinician education and perspective-taking, patient decision tools, and community outreach interventions can help reduce bias and disparities in musculoskeletal pain outcomes. Increasing the diversity of the healthcare workforce should also be a priority. Models of care focused on health equity may provide an ideal framework to reduce bias and provide sustainable improvement in musculoskeletal pain management.

The Imperative for Racial Equality in Pain Science: A Way Forward

Racial equity is imperative to the future and integrity of scientific inquiry. In 2020, citizens of the United States (and globally) witnessed one of the most vile and egregious experiences of police brutality and systemic racism in recent history, the public execution of a Black American man. While some may isolate this and other similar events from influencing the scientific endeavors of pain researchers, events such as this can have a direct impact on the study, lived experience, and expression of pain in Black Americans. To truly understand the biopsychosocial effects of inequality and injustice on pain disparities, we must consider the unintended consequences that our current research approaches have in limiting the reliability and validity of scientific discovery. As we reflect on our current research practices in an effort to improve pain science, this perspective article discusses ways to initiate positive change in order to advance the science of pain in more equitable ways, not just for Black Americans, but for all individuals that identify as part of an underrepresented group. PERSPECTIVE: Elimination of inequities in pain care and research requires the identification, naming, and mitigation of systemic discriminatory and biased practices that limit our understanding of pain disparities. Now is the time to divest from traditional research methods and invest in equitable and innovative approaches to support pain researchers in advancing the science and improving the lives of people with pain.

Digital phenotyping of sleep patterns among heterogenous samples of Latinx adults using unsupervised learning

OBJECTIVE

This study aimed to identify sleep disturbance subtypes ("phenotypes") among Latinx adults based on objective sleep data using a flexible unsupervised machine learning technique.

METHODS

This study was an analysis of sleep data from three cross-sectional studies of the Precision in Symptom Self-Management Center at Columbia University. All studies focused on sleep health in Latinx adults at increased risk for sleep disturbance. Data on total sleep time (TST), time in bed (TIB), wake after sleep onset (WASO), sleep efficiency (SE), number of awakenings (NOA) and the mean length of nightly awakenings were collected using wrist-mounted accelerometers. Cluster analysis of the sleep data was conducted using an unsupervised machine learning approach that relies on mixtures of multivariate generalized linear mixed models.

RESULTS

The analytic sample included 494 days of data from 118 adults (Ages 19-77). A 3-cluster model provided the best fit based on deviance indices (ie, DΔ∼ -75 and -17 from 1- and 2- to 3-cluster models, respectively) and likelihood ratio (P_diff ∼ 0.93). Phenotype 1 (n = 64) was associated with greater likelihood of overall adequate SE and less variability in SE and WASO. Phenotype 2 (n = 11) was characterized by higher NOAs, and greater WASO and TIB than the other phenotypes. Phenotype 3 (n = 43) was characterized by greater variability in SE, bed times and awakening times.

CONCLUSION

Robust digital data-driven modeling approaches can be useful for detecting sleep phenotypes from heterogenous patient populations, and have implications for designing precision sleep health strategies for management and early detection of sleep problems.

How and Why Patient Concerns Influence Pain Reporting: A Qualitative Analysis of Personal Accounts and Perceptions of Others' Use of Numerical Pain Scales

Complex factors influence how people report and interpret numerical pain ratings. Such variability can introduce noise and systematic bias into clinical pain assessment. Identification of factors that influence self-rated pain and its interpretation by others may bolster utility of these scales. In this qualitative study, 338 participants described motivations for modulating their own pain reports relative to a numerical pain scale (0–10), as well as perceptions of others’ pain reporting modulation. Responses indicated that people over-report pain to enhance provider belief/responsiveness or the likelihood of pain relief, and out of fear of future pain or potential illness. Concerns of how one’s pain affects and is perceived by others, and financial concerns motivated pain under-reporting. Unprompted, many participants reported never modulating their pain ratings, citing trust in providers and personal ethics. Similar reasons were assumed to motivate others’ pain ratings. However, participants often attributed others’ over-reporting to internal causes, and their own to external. This bias may underlie common assumptions that patients over-report pain for nefarious reasons, distort interpretation of pain reports, and contribute to pain invalidation. Recognition of patient concerns and one’s own personal biases toward others’ pain reporting may improve patient-provider trust and support precision of numerical pain ratings.

Patient Preference and Risk Assessment in Opioid Prescribing Disparities: A Secondary Analysis of a Randomized Clinical Trial

IMPORTANCE

Although racial disparities in acute pain control are well established, the role of patient analgesic preference and the factors associated with these disparities remain unclear.

OBJECTIVE

To characterize racial disparities in opioid prescribing for acute pain after accounting for patient preference and to test the hypothesis that racial disparities may be mitigated by giving clinicians additional information about their patients' treatment preferences and risk of opioid misuse.

DESIGN, SETTING, AND PARTICIPANTS

This study is a secondary analysis of data collected from Life STORRIED (Life Stories for Opioid Risk Reduction in the ED), a multicenter randomized clinical trial conducted between June 2017 and August 2019 in the emergency departments (EDs) of 4 academic medical centers. Participants included 1302 patients aged 18 to 70 years who presented to the ED with ureter colic or musculoskeletal back and/or neck pain.

INTERVENTIONS

The treatment arm was randomized to receive a patient-facing intervention (not examined in this secondary analysis) and a clinician-facing intervention that consisted of a form containing information about each patient's analgesic treatment preference and risk of opioid misuse.

MAIN OUTCOMES AND MEASURES

Concordance between patient preference for opioid-containing treatment (assessed before ED discharge) and receipt of an opioid prescription at ED discharge.

RESULTS

Among 1302 participants in the Life STORRIED clinical trial, 1012 patients had complete demographic and treatment preference data available and were included in this secondary analysis. Of those, 563 patients (55.6%) self-identified as female, with a mean (SD) age of 40.8 (14.1) years. A total of 455 patients (45.0%) identified as White, 384 patients (37.9%) identified as Black, and 173 patients (17.1%) identified as other races. After controlling for demographic characteristics and clinical features, Black patients had lower odds than White patients of receiving a prescription for opioid medication at ED discharge (odds ratio [OR], 0.42; 95% CI, 0.27-0.65). When patients who did and did not prefer opioids were considered separately, Black patients continued to have lower odds of being discharged with a prescription for opioids compared with White patients (among those who preferred opioids: OR, 0.43 [95% CI, 0.24-0.77]; among those who did not prefer opioids: OR, 0.45 [95% CI, 0.23-0.89]). These disparities were not eliminated in the treatment arm, in which clinicians were given additional data about their patients' treatment preferences and risk of opioid misuse.

CONCLUSIONS AND RELEVANCE

In this secondary analysis of data from a randomized clinical trial, Black patients received different acute pain management than White patients after patient preference was accounted for. These disparities remained after clinicians were given additional patient-level data, suggesting that a lack of patient information may not be associated with opioid prescribing disparities.

Best practices for virtual care to support youth with chronic pain and their families: a rapid systematic review to inform health care and policy during COVID-19 and beyond

Supplemental Digital Content is Available in the Text.

Evidence-informed guidance to better leverage, implement, and select virtual care platforms for pediatric chronic pain, and identified knowledge gaps are in need of additional research.

The COVID-19 pandemic has acutely challenged health systems and catalyzed the need for widescale virtual care and digital solutions across all areas of health, including pediatric chronic pain. The objective of this rapid systematic review was to identify recommendations, guidelines, and/or best practices for using virtual care to support youth with chronic pain and their families (CRD42020184498). MEDLINE, CINAHL, Embase, APA PsychINFO, and Web of Science were searched the week of May 25, 2020, for English language peer-reviewed articles published since 2010 that (1) discussed children and adolescents aged <18 years reporting any type of chronic pain (ie, pain lasting >3 months); (2) focused on any type of virtual care (eg, telephone, telehealth, telemedicine, mHealth, eHealth, online, or digital); and (3) reported on guidelines, best practices, considerations, or recommendations for virtual care. Abstract and full text screening and data extraction were performed in duplicate. Meta-ethnography was used to synthesize concepts across articles. Of 4161 unique records screened, 16 were included addressing diverse virtual care and pediatric chronic pain conditions. Four key themes were identified: (1) opportunities to better leverage virtual care, (2) direct effective implementation of virtual care, (3) selection of virtual care platforms, and (4) gaps in need of further consideration when using virtual care to support youth with chronic pain and their families. No existing guidelines for virtual care for pediatric chronic pain were identified; however, best practices for virtual care were identified and should be used by health professionals, decision makers, and policymakers in implementing virtual care.

Racial and Ethnic Disparities in the Treatment of Chronic Pain

OBJECTIVE

To summarize the current literature on disparities in the treatment of chronic pain.

METHODS

We focused on studies conducted in the United States and published from 2000 and onward. Studies of cross-sectional, longitudinal, and interventional designs were included.

RESULTS

A review of the current literature revealed that an adverse association between non-White race and treatment of chronic pain is well supported. Studies have also shown that racial differences exist in the long-term monitoring for opioid misuse among patients suffering from chronic pain. In addition, a patient's sociodemographic profile appears to influence the relationship between chronic pain and quality of life. Results from interventional studies were mixed.

CONCLUSIONS

Disparities exist within the treatment of chronic pain. Currently, it is unclear how to best combat these disparities. Further work is needed to understand why disparities exist and to identify points in patients' treatment when they are most vulnerable to unequal care. Such work will help guide the development and implementation of effective interventions.

Wearable Devices: Current Status and Opportunities in Pain Assessment and Management

INTRODUCTION

We investigated the possibilities and opportunities for using wearable devices that measure physical activity and physiometric signals in conjunction with ecological momentary assessment (EMA) data to improve the assessment and treatment of pain.

METHODS

We considered studies with cross-sectional and longitudinal designs as well as interventional or observational studies correlating pain scores with measures derived from wearable devices. A search was also performed on studies that investigated physical activity and physiometric signals among patients with pain.

RESULTS

Few studies have assessed the possibility of incorporating wearable devices as objective tools for contextualizing pain and physical function in free-living environments. Of the studies that have been conducted, most focus solely on physical activity and functional outcomes as measured by a wearable accelerometer. Several studies report promising correlations between pain scores and signals derived from wearable devices, objectively measured physical activity, and physical function. In addition, there is a known association between physiologic signals that can be measured by wearable devices and pain, though studies using wearable devices to measure these signals and associate them with pain in free-living environments are limited.

CONCLUSION

There exists a great opportunity to study the complex interplay between physiometric signals, physical function, and pain in a real-time fashion in free-living environments. The literature supports the hypothesis that wearable devices can be used to develop reproducible biosignals that correlate with pain. The combination of wearable devices and EMA will likely lead to the development of clinically meaningful endpoints that will transform how we understand and treat pain patients.
