Losing face: sources of stigma as perceived by chronic facial pain patients

A systematic review with meta-analyses of the association between stigma and chronic pain outcomes

ABSTRACT

Stigma is common in people experiencing chronic pain and there are indications that it may adversely affect pain outcomes. However, to date, there is no systematic review exploring the impact of stigma on chronic pain-related outcomes. This systematic review and meta-analysis aimed to examine the association between stigma and key chronic pain outcomes and differences in stigma between pain conditions. Seven databases were searched for studies reporting a measure of association between stigma and at least one pain outcome in adults with chronic pain. Studies were screened by 2 independent researchers. Nineteen studies met eligibility criteria and data were extracted, quality-assessed, and narratively synthesised and meta-analysed where possible. Meta-analyses of bivariate cross-sectional correlations demonstrated significant positive correlations between stigma and pain intensity, disability, and depression, with small to moderate effects. Data from 2 prospective studies and those only reporting multivariate analyses that were not included in meta-analyses further supported these findings. There was some evidence that individuals who experience pain conditions with less clear pathophysiology may report greater stigma, although more research is needed. The review highlights that there is a growing number of studies on stigma in the pain field showing an adverse association between stigma and chronic pain outcomes.

The social context of burning mouth syndrome: an exploratory pilot study of stigma, discrimination, and pain

BACKGROUND

The social context of burning mouth syndrome (BMS) has received little attention in the scientific literature. However, social psychological theory and insights from those with lived experiences suggest that people living with BMS experience compounding effects of stigma related to their pain, diagnosis (or lack thereof), and intersectional identities.

OBJECTIVE

Our aim is to provide initial evidence and to motivate new directions for research on BMS. Here, we present the results of an exploratory pilot study (n = 16) of women living with BMS in the United States.

METHODS

Participants completed self-report measures of stigma, discrimination, and pain, as well as laboratory assessments of pain through quantitative sensory testing.

RESULTS

Results indicate a high prevalence of internalized BMS stigma, experience of BMS-related discrimination from clinicians, and gender stigma consciousness in this population. Moreover, results provide initial evidence that these experiences are related to pain outcomes. The most robust pattern of findings is that internalized BMS stigma was related to greater clinical pain severity, interference, intensity, and unpleasantness.

CONCLUSION

Given the prevalence and pain-relevance of intersectional stigma and discrimination identified in this pilot study, lived experience and social context should be incorporated into future research on BMS.

Association between Stigma and Pain in Patients with Temporomandibular Disorders

OBJECTIVE

This study aims to explore the association between stigma and pain in patients with temporomandibular disorders (TMDs).

METHODS

Two hundred and twenty-five patients with TMDs were recruited, and they completed the questionnaires including the Visual Analogue Scale of Pain (VAS), Generalized Anxiety Disorder 7-Item (GAD-7), the Patient Health Questionnaire 9-item (PHQ-9), Jaw Functional Limitation Scale 8-item (JFLS-8), the Stigma Scale for Chronic Illness 8-item (SSCI-8), and other demographic and disease-related information. The total score of SSCI-8 indicated overall stigma, which could be classified into 2 subdomains, felt stigma and enacted stigma, according to their representative items, respectively. Then, the patients were divided into 2 groups in each subdomain of stigma according to their scores: stigma group (score ≥ 1) and no stigma group (score = 0).

RESULTS

Patients with overall stigma and enacted stigma presented significantly higher scores in VAS, GAD-7, PHQ-9, and JFLS-8 than those without overall stigma and those without enacted stigma, respectively. Significant differences between patients with and without felt stigma were only observed in GAD-7, PHQ-9, and JFLS-8. Patients with overall stigma and enacted stigma mainly suffered from pain-related TMDs (PTs) and combined TMDs (CTs). Overall stigma and enacted stigma rather than felt stigma were significantly associated with both PTs and CTs. Stigma, including overall stigma, enacted stigma, and felt stigma, was more associated with anxiety and depression and less related to jaw functional limitation of the patients with TMDs.

CONCLUSION

Stigma, specifically enacted stigma, was correlated to pain in patients with TMDs. Stigma was more related to psychological problems than jaw functional limitation.

Psychometric Properties of a Healthcare Provider Burden Scale: Preliminary Results

Measures are lacking of the clinical burden that healthcare providers perceive in treating chronic conditions. This study presents a preliminary psychometric evaluation of a novel self-report measure of provider burden in the treatment of chronic pain. Data for eight burden items were available from vignette studies examining the effects of patient pain severity and medical evidence on clinical burden and judgments for chronic pain. Participants (N = 922) were 109 physicians and 813 non-physicians, all acting in the role of physician (232 community members without chronic pain, 105 community members with chronic pain, and 476 American Chronic Pain Association members with chronic pain). Factor analyses of burden items yielded one-factor solutions in all samples, with high factor loadings and adequate explained variance. Internal consistency reliability was uniformly high (≥ .87). Burden scores were significantly higher among physicians compared to non-physicians; non-physician groups did not differ on any burden score. Significant correlations of burden score with indicators of psychosocial complications in patient care supported scale validity. Burden score was not associated with gender, age, or education. Results provide initial support for the psychometric properties of a Healthcare Provider Burden Scale (HPBS). Research utilizing larger and representative healthcare provider groups is needed.

Patient Perceptions of Physician Burden in the Treatment of Chronic Pain

While patient perceptions of burden to caregivers is of recognized clinical significance among people with chronic pain, perceived burden to treating physicians has not been studied. This study examined how people with chronic pain perceived levels of medical evidence (low vs high) and pain severity (4,6,8/10) to influence physician burden and how burden then mediated expected clinical judgments. 476 people with chronic pain read vignettes describing a hypothetical patient with varying levels of medical evidence and pain severity from the perspective of a treating physician, rated the burden that patient care would pose, and made a range of clinical judgments. The effect of pain severity on clinical judgments was expected to interact with medical evidence and be conditionally mediated by burden. Although no associations with burden were found for the pain severity x medical evidence interaction or for pain severity alone, low levels of supporting medical evidence yielded higher burden ratings. Burden significantly mediated medical evidence effects on judgments of symptom credibility, clinical improvement, and psychosocial dysfunction. Results indicate that perceived physician burden negatively influenced judgments of patients with chronic pain, beyond the direct effects of medical evidence. Implications are discussed for clinical practice, as well as future research. PERSPECTIVE: : People with chronic pain expect physicians to view the care of patients without supporting medical evidence as burdensome. Higher burden is associated with less symptom credibility, more psychosocial dysfunction, and less treatment benefit. Perceived physician burden appears to impact how patients approach treatment, with potentially adverse implications for clinical practice.

Development of an interdisciplinary specialist facial pain management programme

Aims:

This article aims to describe the development of a specialist chronic facial pain (CFP) management programme within an already well-established pain management service, including the content from a multidisciplinary perspective, and present preliminary descriptive 6-month outcomes from patients who have attended the programme.

Methods:

Authors used their clinical experience of working with people who have a diagnosis of CFP. They researched available literature, liaised with CFP support organisations and visited an existing UK-based CFP programme. Programme content was designed based on findings. The roles of pain interdisciplinary team members involved in delivering the programme are described, as well as a brief description of the structure of the programme and programme sessions provided by each discipline.

Results:

Clinical outcomes from programme participants were collected at assessment, end of treatment and 6 months post-treatment, which measured relevant outcomes for a pain management programme (PMP). Outcomes from 36 participants at both end of programme and 6 months following completion of programme demonstrate promising improvements. Qualitative data from patient satisfaction questionnaires completed at the end of programme suggest that providing a CFP-specific programme was beneficial for participants, with the main critique being that the programme sessions should be longer than 45 minutes.

Conclusion:

Attending a CFP-specific programme demonstrated positive 6-month changes in relevant outcome measures for people with CFP. With a small sample size, there is a need for further research into the effectiveness. It would also be beneficial to compare outcomes from the usual PMP treatment with people who have CFP, with outcomes from a CFP-specific programme.

A Preliminary Study of Provider Burden in the Treatment of Chronic Pain: Perspectives of Physicians and People with Chronic Pain

This study compared perceptions of the burden of patient care and associated clinical judgments between physicians and people with chronic pain (PWCP) in a 2 × 3 × 2 between-subjects design that varied participant type, patient-reported pain severity (4/6-8/10), and supporting medical evidence (low/high). One hundred and nine physicians and 476 American Chronic Pain Association members were randomly assigned to 1 of 6 conditions. Respondents estimated the clinical burden they would assume as the treating physician of a hypothetical patient with chronic low back pain, and made clinical judgments regarding that patient. Physician burden ratings were significantly higher than PWCP ratings, and clinical impressions (eg, trust in pain report, medical attribution) and management concerns (eg, opioid abuse risk) were relatively less favorable. Neither pain severity nor medical evidence affected burden ratings significantly. High medical evidence was associated with more favorable clinical impressions; higher pain severity led to more discounting of patient pain reports. Burden was significantly correlated with a range of clinical judgments. Results indicate that physicians and PWCP differ in their perceptions of provider burden and related clinical judgments in ways that could impact treatment collaboration. Further research is needed that examines provider burden in actual clinical practice. PERSPECTIVE: Physicians and people with chronic pain (PWCP) estimated the clinical burden of patient care and made judgments about a hypothetical patient with chronic pain. Physician burden ratings were higher and clinical judgments less favorable, relative to PWCP respondents. These differences could impact treatment collaboration and merit study in clinical practice.

Confirmatory factor analysis of a myalgic encephalomyelitis and chronic fatigue syndrome stigma scale

This study adapted a chronic illness stigma scale and explored its psychometric properties. The main purposes were to confirm the factor structure of the instrument with this population and address the previous factor intercorrelation discrepancies. Five hundred and fifty-four individuals with myalgic encephalomyelitis or chronic fatigue syndrome completed the adapted stigma scale. Results document the stigma experienced by an international sample of individuals with myalgic encephalomyelitis and chronic fatigue syndrome. Factors demonstrated good internal consistency, and a model fit was found in a confirmatory factor analysis. Participants endorsed high levels of stigma, estrangement, and disclosure. Implications of these findings and future directions are discussed.

Improving patient-provider communication about chronic pain: development and feasibility testing of a shared decision-making tool

Background

Chronic pain has emerged as a disease in itself, affecting a growing number of people. Effective patient-provider communication is central to good pain management because pain can only be understood from the patient’s perspective. We aimed to develop a user-centered tool to improve patient-provider communication about chronic pain and assess its feasibility in real-world settings in preparation for further evaluation and distribution.

Methods

To identify and prioritize patient treatment goals for chronic pain, strategies to improve patient-provider communication about chronic pain, and facilitate implementation of the tool, we conducted nominal group technique meetings and card sorting with patients with chronic pain and experienced providers (n = 12). These findings informed the design of the PainAPP tool. Usability and beta-testing with patients (n = 38) and their providers refined the tool and assessed its feasibility, acceptability, and preliminary impact.

Results

Formative work revealed that patients felt neither respected nor trusted by their providers and focused on transforming providers’ negative attitudes towards them, whereas providers focused on gathering patient information. PainAPP incorporated areas prioritized by patients and providers: assessing patient treatment goals and preferences, functional abilities and pain, and providing patients tailored education and an overall summary that patients can share with providers.

Beta-testing involved 38 patients and their providers. Half of PainAPP users shared their summaries with their providers. Patients rated PainAPP highly in all areas. All users would recommend it to others with chronic pain; nearly all trusted the information and said it helped them think about my treatment goals (94%), understand my chronic pain (82%), make the most of my next doctor’s visit (82%), and not want to use opioids (73%). Beta-testing revealed challenges delivering the tool and summary report to patients and providers in a timely manner and obtaining provider feedback.

Conclusions

PainAPP appears feasible for use, but further adaptation and testing is needed to assess its impact on patients and providers.

Trial registration

This study was approved by the University of New England Independent Review Board for the Protection of Human Subjects in Research (012616–019) and was registered with ClinicalTrials.gov (protocol ID: NCT03425266) prior to enrollment. The trial was prospectively registered and was approved on February 7, 2018.

Counseling interactions between patients living with persistent pain and pharmacists in Australia: are we on the same page?

Background

People living with persistent pain in Australia often cannot access adequate care to manage their pain. Therefore, as the most accessible healthcare professionals, community pharmacists have an important role to play in helping to improve patient outcomes. Hence, it is important to investigate patient needs and expectations in terms of counseling interactions with pharmacists, along with pharmacists’ approach to counseling interactions with these patients.

Method

The nature of patient–pharmacist counseling interactions was explored with seven patients (one focus group), and 10 practicing pharmacists (two focus groups, three semi-structured interviews). The themes identified informed the development of an online survey that was advertised online to patients and pharmacists across Australia.

Results

A total of 95 patients and 208 pharmacists completed the survey. Overall, more than half of patients (77/95) were satisfied with the care provided by their pharmacist, but only a third (71/205) of pharmacists were satisfied with the care they provided to patients. The majority of patients (67/94) reported that pharmacists provided good information about medications. This aligned with pharmacists’ responses, as most reported focusing on medication side effects (118/188) and instructions for taking pain medication (93/183) during patient interactions. However, when asked about empathy and rapport from pharmacists, only half to two-thirds (48–61/95) of patients expressed positive views. Overall, half of the patients (39/75) wanted a caring, empathetic, respectful, and private conversation with the pharmacist, and nearly half (40/89) perceived the pharmacist's role as providing (new) information on alternative pharmacological and non-pharmacological therapies, including general advice on pain management.

Conclusion

There was a disparity in the nature of the interaction and information that patients wanted from pharmacists, compared to what was provided by pharmacists. Training and education may help pharmacists to better engage in patient-centered care when interacting with people living with persistent pain, thereby improving health outcomes for these patients.

Depression increases subjective stigma of chronic pain

BACKGROUND

Individuals suffering from mental as well as physical conditions often face stigma, which can adversely affect functioning, treatment seeking, and emotional health. We compared levels of stigma experienced by individuals with depression and/or chronic pain, to contrast the perception of stigma experienced by the sufferers with that of individuals who have never experienced these conditions, and to determine whether depression is related to greater experience of stigma for chronic pain.

METHODS

Four groups of participants (N=236) took part in the study: depression only, chronic pain only, comorbid depression and chronic pain, and healthy controls. Participants underwent a clinical interview and completed a stigma measure that assessed general self-stigma, public stigma, treatment stigma, secrecy, and stigmatizing experiences.

RESULTS

Healthy controls largely underestimated the stigma experienced by individuals with depression, but were not inaccurate in estimating stigma experienced by individuals with chronic pain. Further, individuals with chronic pain alone generally perceived less stigma for their condition than did those with depression alone. However, comorbid individuals perceived worse stigma of chronic pain compared to individuals with chronic pain alone, suggesting that depression may affect the stigma felt by sufferers of conditions other than depression.

LIMITATIONS

Social desirability may have influenced stigma scores. Comparing several groups required adapting a standardized instrument.

CONCLUSIONS

Results suggest that depression may play a role in the social experience of having a health condition, as well as indicate that the general public continues to fail to appreciate the negative social pressures experienced by individuals with mental health conditions.

The role of emotion in psychotherapeutic change for medically unexplained symptoms

OBJECTIVES

Evidence of the contribution of emotional processes to the emergence, maintenance, and experience of medically unexplained symptoms (MUS) suggests that clinical approaches which target these processes could be beneficial. In this study, qualitative methods were used to examine patients' perspectives and subjective experiences of emotional processes in the context of a psychotherapy assessment and treatment service for MUS provided in a hospital emergency department (ED).

METHODS

Seven semi-structured interviews were conducted with ED patients presenting with MUS who received a course of intensive short-term dynamic psychotherapy treatment.

RESULTS

Interpretative phenomenological analysis was employed with three superordinate themes emerging: Barriers to examining emotional processes; reflections on the therapeutic process; psychological change; and improved well-being. Obstacles to clinical engagement in treatment for MUS were described in relation to patients' and therapists' ability to identify, address, and utilize emotion processes. Specific elements of this work were identified as integral components of the psychotherapy change process for MUS.

CONCLUSIONS

Directly observing the physical effects of emotional experiencing in MUS provides sensory evidence that can enable patients to make mind-body connections. Psycho-emotional processes warrant further study to explore the applicability to other conceptual models for assessing and treating MUS. Clinical and methodological significance: In this article, we highlight that Medically Unexplained Symptoms (MUS) are a priority area for both physical and mental health care services. We present findings relevant to the effectiveness of a novel psychotherapy innovation within a hospital emergency department (ED). The use of interpretative phenomenological analysis to study the experiences of ED clients with MUS offers an established qualitative method for exploring the processes underlying therapeutic change. The results provide new insights around obstacles to engagement alongside potential solutions when addressing the psychological needs of clients with MUS. Although emotion processes have been described as a potentially important change process for MUS and in psychotherapy more generally, little empirical research has studied these two areas collectively.

Investigating Trust, Expertise, and Epistemic Injustice in Chronic Pain

Trust is central to the therapeutic relationship, but the epistemic asymmetries between the expert healthcare provider and the patient make the patient, the trustor, vulnerable to the provider, the trustee. The narratives of pain sufferers provide helpful insights into the experience of pain at the juncture of trust, expert knowledge, and the therapeutic relationship. While stories of pain sufferers having their testimonies dismissed are well documented, pain sufferers continue to experience their testimonies as being epistemically downgraded. This kind of epistemic injustice has received limited treatment in bioethics. In this paper, we examine how a climate of distrust in pain management may facilitate what Fricker calls epistemic injustice. We critically interrogate the processes through which pain sufferers are vulnerable to specific kinds of epistemic injustice, such as testimonial injustice. We also examine how healthcare institutions and practices privilege some kinds of evidence and ways of knowing while excluding certain patient testimonies from epistemic consideration. We argue that providers ought to avoid epistemic injustice in pain management by striving toward epistemic humility. Epistemic humility, as a form of epistemic justice, may be the kind disposition required to correct the harmful prejudices that may arise through testimonial exchange in chronic pain management.

Internalized stigma in people living with chronic pain

Although persistent pain occurs in a sociocultural context, the influence of personal devaluation and invalidation is often neglected. As such, the present study sought to consider whether individuals' experience, perception, or anticipation of negative social reactions to their pain may become internalized and affect the self. To examine this issue, 92 adults with chronic pain responded to a questionnaire exploring the presence of internalized stigma and its association with a range of psychological consequences. As predicted, a large percentage of people with chronic pain (38%) endorsed the experience of internalized stigma. The results showed that internalized stigma has a negative relationship with self-esteem and pain self-efficacy, after controlling for depression. Internalized stigma was also associated with cognitive functioning in relation to pain, in terms of a greater tendency to catastrophize about pain and a reduced sense of personal control over pain. Overall, this study presents a new finding regarding the application of internalized stigma to a chronic pain population. It offers a means of extending our understanding of chronic pain's psychosocial domain. Implications are discussed in terms of the potential to inform clinical treatment and resiliency into the future.

PERSPECTIVE

This article presents a novel finding regarding the presence of internalized stigma among people living with chronic pain. Internalized stigma is strongly associated with indicators of patient outcome. It presents an area for future work with the aim to improve our understanding and treatment of people living with pain.

Perceived stereotyping and seeking care for chronic vulvar pain

OBJECTIVES

We examined stereotyping of chronic pain sufferers among women aged 18-40 years and determined whether perceived stereotyping affects seeking care for women with chronic vulvar pain.

DESIGN

Cross-sectional study using a community-based survey of vulvodynia asking if "Doctors think that people with chronic pain exaggerate their pain," and if "People believe that vulvar pain is used as an excuse to avoid having sex".

SETTING AND PARTICIPANTS

Twelve thousand eight hundred thirty-four women aged 18-40 years in metropolitan Minneapolis/St. Paul, Minnesota.

OUTCOME MEASURES

Women were considered to have a history of chronic vulvar pain if they reported vulvar burning lasting more than 3 months or vulvar pain on contact.

RESULTS

Four thousand nine hundred eighty-seven (38.9%) women reported a chronic pain condition; 1,651 had chronic vulvar pain. Women experiencing chronic pain were more likely than those without to perceive stereotyping from both doctors and others; a dose-response with the number of pain conditions existed. Women with chronic vulvar pain were more likely to believe that people think vulvar pain is an excuse to avoid intercourse. Half of the women with chronic vulvar pain did not seek medical care for it; of these, 40.4% perceived stereotyping from doctors. However, it was women who actually sought care (45.1%) who were more likely to feel stigmatized by doctors (adjusted relative risk = 1.11, 95% confidence interval: 1.01-1.23).

CONCLUSIONS

Perceived negative stereotyping among chronic pain sufferers is common, particularly negative perceptions about physicians. In fact, chronic vulvar pain sufferers who felt stigmatized were more likely to have sought care than those who did not feel stigmatized.

Patient self-report measures of chronic pain consultation measures: a systematic review

BACKGROUND

Earlier studies have associated improvements in chronic pain outcomes with various consultation attributes, including: the legitimization of people's chronic pain experience, affective components of the therapeutic relationship, and reaching decisions about people's care through collaboration. Although studies have used patient self-report measures to examine how certain aspects of consultations contribute to managing chronic pain. The psychometric quality of these measures seems to have not been independently appraised to date.

OBJECTIVES

This review aimed to evaluate the psychometric properties and administrative feasibility of published patient self-report consultation measures that were validated for people with chronic pain.

METHODS

Databases were searched to identify patient self-report consultation measures validated in chronic pain populations. Explicit review criteria for 8 measure attributes were developed for this review by synthesizing information from available guidelines. In total, 58 potentially relevant consultation measures were identified. Of these, 4 measures satisfied the inclusion/exclusion criteria and were critically appraised by 2 independent reviewers. Overall, the psychometric quality of the included measures was modest, particularly in terms of evidence for content validity, test-retest reliability, responsiveness, and interpretability.

DISCUSSION

Each of the included measures assessed differing aspects of consultations, and their potential clinical and research uses are discussed. Recommendations are made to improve the psychometric quality of the included measures. In summary, more psychometric research needs to be undertaken to improve the existing measures' quality and broaden the scope of chronic pain consultation measures before studies may be conducted to develop a comprehensive understanding of the manner in which consultation attributes influence chronic pain outcomes.

How depressive symptoms correlate with stigma perception of mental illness

INTRODUCTION

The aim of this study was to survey the attitudes of 115 patients with the diagnosis of somatoform pain disorder, toward anticipated discrimination and mental illness stigma and how it is influenced by depressive symptoms.

METHOD

115 consecutive in- and outpatients with somatoform pain disorder (mean age: 50 +/- 11 years; 62% female) from the Department of Psychiatry and Psychotherapy, Medical University of Vienna, were administered a modified 12-item version of Link's Perceived Stigma Questionnaire and the Beck Depression Inventory.

RESULTS

With regard to close personal relationships, such as taking care of children or dating, somatoform pain patients showed a rather high perceived stigma score (over 70% for both items). Also nearly 70% think that 'most employers' would pass over the application of a psychiatric patient in favour of another applicant. The overall results show a significant correlation with depressive symptoms (r = 0.228 and p = 0.014).

CONCLUSION

Fear of stigma increases with depressive symptoms and both are a risk for treatment delay. The goal of future research should be the question how to reduce subjective stigma experiences of the patients affected in order to help them enter psychiatric treatment early and gain self-confidence and mental health back again.

Patient-provider interactions in the management of chronic pain: current findings within the context of shared medical decision making

OBJECTIVE

This article reviews the literature on patient-provider interactions among patients with chronic pain conditions with an emphasis on shared medical decision making.

RESULTS

Key findings suggest that: 1) patients with chronic pain and health care providers are likely to have opposing attitudes and goals, with patients seeking "to be understood as individuals" and struggling to have their pain concerns legitimized while their health care providers may place a greater focus on diagnosis and treatment than quality of life concerns; and 2) female patients may face additional challenges when communicating their pain concerns with providers. Increased emphasis on communication training and efforts to promote a shared decision making process are proposed as possible mechanisms to improve patient-provider interactions.

CONCLUSIONS

Treatment of chronic pain is often complex and may be further complicated when patients and health care providers have differing goals and attitudes concerning treatment. Difficulties in engaging in collaborative treatment decision making may result. Efforts to enhance patient-provider communication as well as to systematically examine nonspecific treatment factors are likely to promote effective management of chronic pain.

Biopsychosocial pain medicine and mind-brain-body science

This article reviews how emotions, behavior, and psychiatric comorbidity influence the course and outcome of chronic pain disorders and addresses methods of identifying and managing these problems in clinical practice. Successful medical rehabilitation for patients with chronic pain requires (1) appreciating the effects of biopsychosocial factors in the onset, course, and outcomes of pain disorders; (2) understanding neurobiologic mechanisms linking mind, brain, and body in the functions of pain perception and modulation; and (3) being able to review critically and use selectively the plethora of new medications and interventional technologies that are proposed in the literature. Deficits in these skills now are recognized as hazardous to the public health so that medical school education and post residency training in pain medicine is now mandatory in some states.

The case for pain medicine

Pain Medicine has its roots in multiple primary specialties and has developed into a discrete specialty with disparate practice styles. Its identity is in flux and is threatened by forces that may fragment this new field before it can set firm roots. The public health crisis of under treated pain parallels medicine's struggle to adequately classify Pain Medicine as a specialty. We review the case for Pain Medicine as a discrete discipline, with specialized knowledge, treatments, training and education. Without recognition of the specialty of Pain Medicine, and resolution of the fragmentation of the field throughout healthcare, medicine's approach to the current problem of under treated pain is likely to continue to be inadequate.

Familial aggregation of depression in fibromyalgia: a community-based test of alternate hypotheses

Numerous studies report that fibromyalgia (FM), a syndrome characterized by widespread pain and generalized tender points, is comorbid with major depressive disorder (MDD). The current study tests two alternate explanations for their comorbidity using a family study methodology. The first is that FM is a depression spectrum disorder. The second is that depression is a consequence of living with FM. We recruited potential probands by initially screening by telephone for FM and MDD among women in the NY/NJ metropolitan area, randomly selecting telephone numbers from a list of households with women. Eligible women were invited for second stage physical examinations for FM diagnosis and psychiatric interviews for MDD diagnosis. All available adult, first-degree relatives received psychiatric interviews. Relatives of probands were divided into four groups on the basis of the probands' FM and MDD diagnoses (FM+/MDD+ (n = 156), FM+/MDD- (n = 51), FM-/MDD+ (n = 351) and FM-/MDD- (n = 101)). Results indicated that rates of MDD in the relatives of probands with FM but without personal histories of MDD were virtually identical to rates of MDD in relatives of probands with MDD themselves. This outcome is consistent with the hypothesis that FM is a depression spectrum disorder, in which FM and MDD are characterized by shared, familially mediated risk factors. The implications of these findings for a stress-vulnerability model of FM are discussed.

Interstitial cystitis and pelvic floor dysfunction: a comprehensive review

Interstitial cystitis is a clinical condition occurring predominantly in women and is characterized by urinary frequency, urgency, and pain. Patient symptoms have the potential to significantly affect quality of life, posing a challenge to some to perform activities of daily living. This article comprehensively reviews the literature on the epidemiology, etiology, evaluation, and treatment of interstitial cystitis, and considers commonly associated pelvic floor dysfunction.

Palliative pharmaceutical care: a randomized, prospective study of telephone-based prescription and medication counseling services for treating chronic pain

OBJECTIVE

To evaluate the effects of providing a unique telephone-based pharmaceutical care program to a sample of patients enrolled at a university pain clinic in Philadelphia, Pa. We hypothesized that in comparison to routine pharmaceutical care, the telephone-based pharmaceutical care program would have a positive impact on delivery of medication, quality of life, and overall satisfaction with the pain clinic program.

PATIENTS

One hundred seven pain clinic patients were randomly assigned to the control and intervention groups. Seventy-four patients (control group, n = 36; intervention group, n = 38) met inclusion criteria.

METHOD

The control group continued to receive care and prescription services through the same means as prior to the study. There were 2 components to the pharmaceutical care program offered to the intervention group. The first component consisted of a palliative care pharmacy company, PainRxperts, providing specialized prescription services tailored to the needs of a pain medicine clinical practice. The second component involved the palliative-trained pharmacist's proactive monitoring of patient pharmacotherapy for potential or actual drug related problems (DRPs).

RESULTS

Intervention patients perceived that they had better access to medication, more efficient processing of prescriptions, and fewer stigmatizing experiences. They also endorsed pharmacists' behavioral interventions such as medication counseling, availability to answer medication-related questions, and non-judgmental attitudes when managing opioid prescriptions.

CONCLUSION

This study suggests that the palliative-trained pharmacist can play an important collaborative role in managing chronic pain. Application of the pharmaceutical care model in pain medicine centers can improve satisfaction and remove some of the barriers to good pharmaceutical care facing patients with chronic pain disorders

"What do you mean 'what's wrong with her?'": stigma and the lives of families of children with disabilities

This study extends the application of modified labeling theory to the experience of courtesy stigma in families of children with disabilities. The study utilizes a mixed methods approach that integrates quantitative analysis of survey data, qualitative analysis of interactive interviews and personal narrative. A survey of 81 mothers of children with disabilities in Florida, USA, is used to test hypotheses related to the impact of perceived stigma on emotional and social outcomes for mothers and children. The author's experience as the mother of a child with cerebral palsy and interactive interviews with seven other mothers with similar experiences are used to contextualize, humanize and help interpret the quantitative findings. Results indicate that controlling for the effects of salient maternal and child characteristics and the daily hassles of caring for a child with a disability (objective burden), maternal perceptions that individuals with disabilities are devalued and discriminated against (stigmatized) by others increases maternal distress (subjective burden). Findings also indicate that children of mothers who perceive high levels of stigma interact less frequently with age peers in the informal settings of homes and neighborhoods.

Childhood victimization and pain in adulthood: a prospective investigation

Evidence of the relationship between childhood abuse and pain problems in adulthood has been based on cross-sectional studies using retrospective self-reports of childhood victimization. The objective of the current study was to determine whether childhood victimization increases risk for adult pain complaints, using prospective information from documented cases of child abuse and neglect. Using a prospective cohort design, cases of early childhood abuse or neglect documented between 1967 and 1971 (n = 676) and demographically matched controls (n = 520) were followed into young adulthood. The number of medically explained and unexplained pain complaints reported at follow-up (1989-1995) was examined. Assessed prospectively, physically and sexually abused and neglected individuals were not at risk for increased pain symptoms. The odds of reporting one or more unexplained pain symptoms was not associated with any childhood victimization or specific types (i.e. sexual abuse, physical abuse, or neglect). In contrast, the odds of one or more unexplained pain symptoms was significantly associated with retrospective self-reports of all specific types of childhood victimization. These findings indicate that the relationship between childhood victimization and pain symptoms in adulthood is more complex than previously thought. The common assumption that medically unexplained pain is of psychological origin should be questioned. Additional research conducting comprehensive physical examinations with victims of childhood abuse and neglect is recommended.

Somatosensory Amplification and Affective Inhibition Are Elevated in Myofascial Face Pain

OBJECTIVE

This study was designed to determine whether affective inhibition and somatosensory amplification are elevated in patients with a history of myofascial face pain (MFP). These processes may underlie a tendency to express distress in somatic rather than affective terms, leading to somatized or masked depression.

DESIGN

Women (n = 162) with a history of MFP were compared with demographically equivalent women (n = 173) without MFP histories on self-report scales of affective inhibition and somatosensory amplification. Structured psychiatric interviews and health histories were conducted. In addition, a first-degree relative of 106 myofascial face pain subjects and 118 control subjects completed these same self-report scales.

RESULTS

MFP cases and controls differed significantly on measures of affective inhibition and somatosensory amplification. History of depression or current psychological distress did not account for group differences. Elevated levels of somatosensory amplification were confined to MFP women with active symptoms. Finally, although both somatosensory amplification and affective inhibition showed a tendency to run in families, familial transmission did not account for case/control differences.

CONCLUSIONS

Affective inhibition and somatosensory amplification are likely to be elevated in patients with MFP. Although not accounted for by psychiatric symptomatology, the possibility that these response styles are reactive to coping with chronic face pain cannot be ruled out.

Attitudes toward patient expertise in chronic illness

Although it has become an accepted standard to acknowledge the patient as a full partner in health care decisions, replacing traditional authoritative relationships with those based on an emancipatory model, the experiences of persons living with chronic illness confirm that this paradigm shift is not yet apparent in many health care relationships. In this paper, the authors present a qualitative secondary analysis of combined data sets from their research into chronic illness experience with two quite different chronic diseases - Type I Diabetes (a socially legitimized chronic disease) and Environmental Sensitivities (a disease which is currently treated with considerable scepticism). Comparing the experiences of individuals with diseases that are quite differently socially constructed, it becomes possible to detect common underlying health professional values and attitudes that powerfully influence the experience of living with and negotiating health care for a chronic illness. In the discussion of findings from this study, the authors examine the implications of the spiral of behaviors that fuels mutual alienation in chronic illness care relationships if professionals are unable to value patient expertise.

Why is depression comorbid with chronic myofascial face pain? A family study test of alternative hypotheses

A number of explanations have been proposed to account for findings that rates of depression are elevated in persons with chronic, non-malignant pain disorders (CNPDs); for example, that CNPDs are variants of depression (e.g. 'masked depression'), that the stress of living with CNPDs contribute to the onset of depression ('diathesis-stress'), or that the correlation of CNPDs and depression is a methodological artifact of studying treatment-seeking samples. These alternative hypotheses are tested for one specific CNPD, chronic myofascial face pain, using a family study methodology. The procedure was to conduct direct psychiatric interviews with 106 patients with a history of carefully diagnosed myofascial face pain, 118 acquaintance controls without personal histories of myofascial face pain, and a random sample of adult first degree relatives of these case and control probands. The probands were further subdivided into four roughly equal samples consisting of cases with and without personal histories of major depressive disorder (MDD), and controls with and without personal histories of MDD. Dates of initial onsets of myofascial face pain and MDD in patient probands were obtained from interviews and records. The main results were that, compared to control probands without personal histories of MDD, MDD and depressive spectrum disorders (DSD) were elevated in the first degree relatives of control probands with personal histories of early onset MDD, but not in the first degree relatives of myofascial face pain probands with or without personal histories of early or late onset MDD. This outcome is consistent with the hypothesis that living with chronic myofascial face pain contributes to elevated rates of depression. It is inconsistent with the alternative hypotheses that this CNPD is a variant of depression or that the elevated MDD rates are simply an artifact of selection into treatment. The implications of these results and additional results consistent with them are discussed.

Treatment planning in pain medicine. Integrating medical, physical, and behavioral therapies

This article addresses a systematic approach to the treatment of chronic pain. The first section presents a biopsychosocial model of pain. The second section presents an application of the biopsychosocial approach to the clinical assessment and management of clinical cases with chronic pain.

Medically unexplained chronic orofacial pain. Temporomandibular pain and dysfunction syndrome, orofacial phantom pain, burning mouth syndrome, and trigeminal neuralgia

Orofacial pain syndromes pose a dilemma for physicians. Even when the patient is referred, quality medical care requires that the physician be acquainted with current evidence-based practice. Such practice may be radically different from the traditional view. This article reviews the differential diagnosis and treatment of the most common medically unexplained orofacial syndromes.

Primary care and pain medicine. A community solution to the public health problem of chronic pain

The author emphasizes that pain is an important public health problem that demands attention. He discusses ineffective management and its causes, administrative and socioeconomic problems perpetuating poor care, problems in technology transfer, organizational models, specialists and subspecialists, and other topics.

Stigma associated with onchocercal skin disease among those affected near the Ofiki and Oyan Rivers in western Nigeria

Skin diseases have been a major source of social stigma, whether they be infectious or not. The potential stigamtizing effect of skin disease associated with onchocerciasis is currently receiving attention because half of the 17 million victims of onchocerciasis in Africa live where the non-blinding form of the disease is prevalent. Some reports are available that onchocercal skin disease (OSD) is associated with social stigma including problems in finding a marriage partner. Previous studies have also implied positive effects of ivermectin treatment on OSD. Therefore a multi-country trial of ivermectin is underway to test the hypothesis that ivermectin treatment might affect perceptions of stigma associated with OSD. This paper presents the baseline stigma findings from the study site located in southwestern Nigeria. A total of 1032 persons living in villages near the Ofiki and Oyan Rivers were screened and interviewed and 500 (48%) were found to have an onchocercal skin lesion. A 13-item, 39-point stigma scale was used in interviews with affected persons. A mean score of 16.8 was obtained. No personal characteristics or disease factors were found to be associated with stigma score. The highest ranking items focused on issues of self-esteem such as feeling embarrassed, feelings of being pitied, thinking less of oneself, feeling that scratching annoys others, feeling that others thought less of the person and feeling that others had avoided the person. During the interviews it was discovered that only about half of those clinically diagnosed as having OSD labeled their own condition as onchocerciasis. Those who said their lesion was OSD had a lower stigma score than those who did not, conforming with previous studies wherein affected persons perceived less stigma from OSD than those without the disease. A broader community perspective on OSD was obtained through 50 interviews using paired comparisons of five skin-related local illnesses. Onchocerciasis placed midway in aversive responses between the higher end represented by leprosy and chicken pox and lower scoring papular rashes known locally as eela and ring worm. In-depth village based interviews yielded several case studies of how onchocerciasis had a negative social impact on its victims. While study on the cultural perceptions of OSD is recommended, the results indicate that with a fairly high prevalence of OSD, the community level effects of social stigma should be regarded as serious.

When did your pain start?: reliability of self-reported age of onset of facial pain

OBJECTIVE

This study was designed to examine the reliability of self-reported onset of facial pain over a relatively long period, as well as factors that may influence the ability of patients to provide consistent pain onset dates. The implications of dating unreliability on assessing the temporal order of two potentially related disorders is also considered.

DESIGN

A total of 125 women with a lifetime history of temporomandibular pain and dysfunction syndrome (TMPDS) were asked to report their pain onset date in the context of a structural health interview. Dates were compared with onset dates recorded an average of 7 years earlier in their clinical chart. Factors potentially affecting reliability of recall were also assessed.

RESULTS

The absolute value of the discrepancy between the two reports was nearly 4 years. Only 26% reported onset dates within the same year. Forward-telescoping, in which events are recalled as occurring more recently than they actually occurred, was more common than backward-telescoping of onset dates. Intraclass correlations were good to excellent (ICC = .80 for full sample). Elapsed time between reports was the largest predictor of reporting discrepancy.

CONCLUSIONS

These findings indicate that a single patient's report of pain onset, especially when he or she is asked to recall the onset of a long-standing pain problem, will most often lead to an underestimate of chronicity. However, high intraclass correlations indicate that patients' dating of pain onset may have satisfactory reliability for research purposes, when comparing a group of patients to one another to assess relative chronicity of pain.

Iatrogenic factors and chronic pain

OBJECTIVE

Although it is accepted that the etiology of chronic pain is multifactorial, little attention has been given to the possible role of iatrogenesis. The aim of the present study is to identify possible iatrogenic factors in chronic pain patients.

METHODS

We report a cross-sectional study of 125 patients attending specialist pain clinics in South London. Data were collected using semistructured checklists. Patients were interviewed with a structured psychiatric interview and were given a questionnaire booklet to complete.

RESULTS

We found that possible iatrogenic factors, such as over-investigation, inappropriate information and advice given to patients as well as misdiagnosis, over-treatment, and inappropriate prescription of medication were common in this sample.

CONCLUSIONS

We suggest that future studies should take account of the role of the doctors, as well as that of the patients, in the etiology, and hence prevention of chronic pain.

Patterns of TMJ surgery: evidence of sex differences

This study investigated the records from one insurance company's reimbursed claims for any TMD-related treatment. Females were disproportionately represented among those treated by surgical means.

Evidence-based care of musculoskeletal facial pain: implications for the clinical science of dentistry

The authors assert that advancement of dentistry as a clinical science has been hampered by a failure to practice evidence-based care, which incorporates principles derived from clinical epidemiology. The schism between the cultures of researcher and practitioner was most evident at a recent National Institutes of Health Technology Assessment Conference on the Management of Temporomandibular Disorders.

Temporomandibular pain and dysfunction syndrome. History, physical examination, and treatment

A stepwise method for treating TMPDS is presented. Step 1-start patient on a regimen of chloroethane or chlorofluorocarbon spray and exercise. Step 1A--if a clicking joint is the chief complaint, start with click exercise. Step 1B--if restricted mouth opening is the chief complaint, start with range of motion exercise; employ exercises sequentially, not simultaneously. Step 2--if pain is moderate to severe, start with amitriptyline 10 mg at bedtime, increasing the dose in 10-mg increments to 40 mg. Step 3--for nonresponders, add injections of tender points with lidocaine and consider a trial of a different tricyclic. Step 4--for nonresponders, consider a trial of tender point injections combining dexamethasone with local anesthetic. Start by injecting the three most painful tender points with 0.5 mL of a solution of 1 mg of dexamethasone combined with two thirds bupivacaine and one third lidocaine to reach the desired volume. Repeat injections, varying the sites as required. Do this once weekly for 4 to 6 weeks for an adequate trial. This regimen can be continued for an extended period of time with appropriate precautions in place. The value of judgment-free psychosocial support cannot be overemphasized. Patients with TMPDS are faced with long-term problems of pain management. An understanding clinician can provide the sustained support required to prevent the cycle of ever more invasive treatments with their potential for harm.

Referral delay in back pain patients on worker's compensation

Low back pain (LBP), a common illness that may progress to chronic disability, costs many billions for care, lost work, and compensation. Conventional medicine does not effectively restore chronic LBP patients to work; multidisciplinary rehabilitation does, but limited or delayed access risks unnecessary costs, additional morbidity, and permanent disability. The authors examine costs of delayed treatment for 23 disabled LBP patients in a rehabilitation program. Compensation costs average $26,159 per patient, a sum covering treatment for 3 patients. Additional medical and societal costs are estimated. Factors causing delay, such as economic incentives and ignorance about pain, and policies to remediate these problems, are discussed.

Orofacial phantom pain: theory and phenomenology

Developing a treatment strategy for patients who are in chronic pain can be challenging for any health care professional, particularly when traditional measures to relieve pain are ineffective. Pain treatment can be further complicated by phenomena known as phantom pain--most often associated with limb amputation. The author describes three phantom syndromes experienced in the orofacial region: phantom tooth pain, phantom bite syndrome and intraoral stump pain.
