Medically Unexplained Symptoms: Exacerbating Factors in the Doctor-Patient Encounter

Communication interventions for medically unexplained symptom conditions in general practice: A systematic review and meta-analysis of randomised controlled trials

Background

Medically unexplained symptoms (MUS) account for 3–50% of all General Practitioner (GP) consultations and are difficult to diagnose due to their unknown aetiology, symptom overlap between conditions, and lack of effective treatment options. MUS patients’ and primary care clinicians frequently face challenges during consultations, with GPs reporting difficulty identifying and classifying MUS, whilst patients report stigma and feeling illegitimised by clinicians. Communication interventions have been proposed as a method to facilitate the doctor-patient relationship and aid the management of MUS.

Aim

This systematic review aims to evaluate the effectiveness of primary care based communication interventions at improving MUS patients’ and/or clinician outcomes.

Method

Four electronic databases were searched from inception to November 2021. Two researchers independently undertook screening, data extraction and quality appraisal. Given the heterogeneous nature of the studies identified, narrative syntheses were conducted, along with meta-analyses where possible to pool data.

Results

9 papers from 10 Randomised Controlled Trials were included. The included studies displayed considerable risk of bias and poor reporting. Some limited evidence suggests that communication interventions tailored to MUS and not following a pre-specified model (such as reattribution) could improve pain, mental and physical functioning whilst reattribution training may improve clinician confidence treating MUS. However, methodological limitations mean that these findings should be interpreted with caution.

Conclusion

A range of interventions for improving communication with MUS patients in primary care have been evaluated. However, the heterogeneous nature of existing evidence and poor study quality mean we cannot conclude whether these interventions are effective. Before considering further randomised controlled trials researchers should focus on developing a new or modified communication intervention for MUS patients and their clinicians.

Trail registration

The systematic review was prospectively registered with PROSPERO (registration record CRD42020206437).

The effect of personalized invalidation of symptoms by healthcare providers on patient depression: The mediating role of self-esteem

OBJECTIVES

Qualitative research has thoroughly investigated the diagnostic journeys of patients, who have often reported difficulty with healthcare providers regarding the acknowledgement of an organic, pathological cause for their symptoms (hereafter referred to as invalidation of symptoms). These encounters also reportedly contributed to reductions in self-esteem and to feelings of depression, particularly prior to diagnosis. The aim of this research was to quantitatively validate these observed relationships and examine the potential compounding effect of personalization of this reported invalidation.

METHODS

Participants were 609 patients with self-reported endometriosis from a larger online research study. Invalidation and personalization of invalidation were measured with survey items developed for this research. Self-esteem and depression were assessed with well-known validated and reliable self-report instruments. Hierarchical linear regressions were performed, with path analysis to test for mediation.

RESULTS

Invalidation predicted self-esteem but not depression. However, when personalized, invalidation predicted both self-esteem and depression. Path analysis testing the effect of personalization of invalidation on depression through self-esteem was significant, demonstrating full mediation.

CONCLUSIONS

Results confirm qualitative research and provide the first known quantitative support that invalidation, particularly when personalized, can be associated with reduced self-esteem and, in turn, greater depression.

PRACTICE IMPLICATIONS

These findings demonstrate an important barrier to patient-centered communication.

The general practitioners perspective regarding registration of persistent somatic symptoms in primary care: a survey

Background

Persistent somatic symptoms (PSS) are common in primary care and often accompanied by an increasing disease burden for both the patient and healthcare. In medical practice, PSS is historically considered a diagnosis by exclusion or primarily seen as psychological. Besides, registration of PSS in electronic health records (EHR) is unambiguous and possibly does not reflect classification adequately. The present study explores how general practitioners (GPs) currently register PSS, and their view regarding the need for improvements in classification, registration, and consultations.

Method

Dutch GPs were invited by email to participate in a national cross-sectional online survey. The survey addressed ICPC-codes used by GPs to register PSS, PSS-related terminology added to free text areas, usage of PSS-related syndrome codes, and GPs’ need for improvement of PSS classification, registration and care.

Results

GPs (n = 259) were most likely to use codes specific to the symptom presented (89.3%). PSS-related terminology in free-text areas was used sparsely. PSS-related syndrome codes were reportedly used by 91.5% of GPs, but this was primarily the case for the code for irritable bowel syndrome. The ambiguous registration of PSS is reported as problematic by 47.9% of GPs. Over 56.7% of GPs reported needing additional training, tools or other support for PSS classification and consultation. GPs also reported needing other referral options and better guidelines.

Conclusions

Registration of PSS in primary care is currently ambiguous. Approximately half of GPs felt a need for more options for registration of PSS and reported a need for further support. In order to improve classification, registration and care for patients with PSS, there is a need for a more appropriate coding scheme and additional training.

The need for a standardized conceptual term to describe invalidation of patient symptoms

In this paper, I comment on a growing literature documenting that many patients perceive their symptoms have been dismissed, ignored, not taken seriously, not believed, etc. (i.e. invalidated) by healthcare providers. I provide a narrative review of research reporting on this patient-provider phenomenon, invalidation of patient symptoms, in various illness contexts in order to highlight the variability concerning how scholars have been referring to the seemingly same phenomenon. Next, I discuss the challenges this variability poses for scholarship, including how it precludes the ability to build on our understanding of how it contributes to the patient experience and related health outcomes. I conclude with recommendations for future research.

Electronic Delivery of Pain Education for Chronic Overlapping Pain Conditions: A Prospective Cohort Study

OBJECTIVE

To examine the impact of educational materials for chronic overlapping pain conditions (COPCs), the feasibility of delivering materials online, and to explore its impact on self-reported self-management applications at 3-month follow-up.

DESIGN

Prospective cohort study.

SETTING

Online.

SUBJECTS

Individuals from a university-wide active research repository with ≥1 coded diagnostic COPC by ICD-9/10 in the medical record.

METHODS

We determined the number of COPCs per participant as indicated by diagnostic codes in the medical record. Consenting participants completed self-report questionnaires and read educational materials. We assessed content awareness and knowledge pre- and post-exposure to education. Comprehension was assessed via embedded questions in reading materials in real time. Participants then completed assessments regarding concept retention, self-management engagement, and pain-related symptoms at 3-months.

RESULTS

N = 216 individuals enrolled, with 181 (84%) completing both timepoints. Results indicated that participants understood materials. Knowledge and understanding of COPCs increased significantly after education and was retained at 3-months. Patient characteristics suggested the number of diagnosed COPCs was inversely related to age. Symptoms or self-management application did not change significantly over the 3-month period.

CONCLUSIONS

The educational materials facilitated teaching of key pain concepts in self-management programs, which translated easily into an electronic format. Education alone may not elicit self-management engagement or symptom reduction in this population; however, conclusions are limited by the study's uncontrolled design. Education is likely an important and meaningful first step in comprehensive COPC self-management.

The Role of Descending Pain Modulation in Chronic Primary Pain: Potential Application of Drugs Targeting Serotonergic System

Chronic primary pain (CPP) is a group of diseases with long-term pain and functional disorders but without structural or specific tissue pathologies. CPP is becoming a serious health problem in clinical practice due to the unknown cause of intractable pain and high cost of health care yet has not been satisfactorily addressed. During the past decades, a significant role for the descending pain modulation and alterations due to specific diseases of CPP has been emphasized. It has been widely established that central sensitization and alterations in neuroplasticity induced by the enhancement of descending pain facilitation and/or the impairment of descending pain inhibition can explain many chronic pain states including CPP. The descending serotonergic neurons in the raphe nuclei target receptors along the descending pain circuits and exert either pro- or antinociceptive effects in different pain conditions. In this review, we summarize the possible underlying descending pain regulation mechanisms in CPP and the role of serotonin, thus providing evidence for potential application of analgesic medications based on the serotonergic system in CPP patients.

Quantifying implicit uncertainty in primary care consultations: A systematic comparison of communication about medically explained versus unexplained symptoms

OBJECTIVE

General practitioners (GPs) disclose more uncertainty (e.g. "I don't know") in consultations with patients presenting medically unexplained symptoms (MUS) versus medically explained symptoms (MES), which could negatively affect patient outcomes. This study assessed if this pattern also holds for more subtle, implicit uncertainty expressions (e.g. "maybe", "might") during different consultation phases, and assessed their relation to patient pre-post consultation anxiety.

METHODS

We quantified implicit markers of uncertainty of 18 GPs in 82 consultations about MUS or MES during different consultation phases. Relative frequencies of implicit uncertainty per consultation were regressed on differences in momentary anxiety pre and post consultation.

RESULTS

We coded 2590  GP utterances. Uncertainty expressions were more frequent in MUS versus MES consultations (OR = 1.54, p = .004), especially during diagnosis and treatment recommendations compared to physical examinations (OR =0 .45, p = .001). Implicit uncertainty was not related to patients' changes in anxiety (b = -0.11, p = .817).

CONCLUSIONS

GPs express more uncertainty during MUS (versus MES) consultations, especially during the diagnostic phase and treatment recommendations. This does not necessarily affect patient anxiety.

PRACTICE IMPLICATIONS

Implicit uncertainty expressions reflect the mere complexity of communicating a medically unexplained diagnosis, which does not affect patient anxiety.

Medicine is Patriarchal, But Alternative Medicine is Not the Answer

Women are over-represented within alternative medicine, both as consumers and as service providers. In this paper, I show that the appeal of alternative medicine to women relates to the neglect of women's health needs within scientific medicine. This is concerning because alternative medicine is severely limited in its therapeutic effects; therefore, those who choose alternative therapies are liable to experience inadequate healthcare. I argue that while many patients seek greater autonomy in alternative medicine, the absence of an evidence base and plausible mechanisms of action leaves patients unable to realize meaningful autonomy. This seems morally troubling, especially given that the neglect of women's needs within scientific medicine seems to contribute to preferences for alternative medicine. I conclude that the liberatory credentials of alternative medicine should be questioned and make recommendations to render scientific medicine better able to meet the needs of typical alternative medicine consumers.

The Four-Cluster Spectrum of Mind-Body Interrelationships: An Integrative Model

Despite the shift toward a biopsychosocial paradigm of medicine, many physicians and mental health professionals (MHPs) find it difficult to treat patients with psycho-somatic disorders. This situation is particularly troublesome due to the high prevalence of these conditions. Although progress has been made over the last few decades in understanding mechanisms underlying the mind-body relationship, disparities remain between research and its clinical implementation. One possible reason for this is the lack of a comprehensive, agreed-upon model that incorporates a biopsychosocial framework and is rooted in an understanding of the various psychobiological pathways. Such a model would enable better communication between physicians and MHPs, allowing them to provide coordinated, stratified treatment. In this paper, four archetypal case studies, together with standard care options are presented to illustrate the current state of affairs. A four-tiered conceptual model of mind-body interrelationships based on pathophysiological and psychopathological mechanisms is suggested to help optimize the treatment of somatic complaints. This Four-Cluster model consists of: (1) Organic Conditions: Structural, or degenerative processes that can affect mood and psychological responses but are not clearly exacerbated by stress. (2) Stress Exacerbated Diseases: Biological disorders with a distinct pathophysiology, such as inflammatory or autoimmune diseases, whose progression is clearly exacerbated by stress. (3) Functional Somatic Syndromes: Conditions wherein heightened sensitivity to stimuli together with hyper-reactivity of the autonomic system form a "vicious cycle" of mutually enhancing learning processes. These processes involve biological mechanisms, such as central sensitization and psychological mechanisms such as catastrophization and selective attention. (4) Conversion Disorder: Physical manifestations of psychological distress, expressed somatically. Symptoms are solely an expression of problems in patients' psychic functioning and are not caused by biological pathology. Finally, suggested management of the aforementioned case studies is presented through the lens of the Four-Cluster model and a proposed integration of our model with existing theories is discussed. As it is rooted in an understanding of psychobiological pathways of illness, the proposed model enables a new way to discern which form of mind-body interaction is manifesting in different diseases and proposes a way to coordinate treatment plans accordingly, to enhance the accuracy and efficacy of care.

Epistemological and methodological paradoxes: secondary care specialists and their challenges working with adolescents with medically unexplained symptoms

Background

Early adolescence is considered a critical period for the development of chronic and recurrent medically unexplained symptoms (MUS), and referrals and system-initiated patient trajectories often lead to an excess of examinations and hospitalizations in the cross-section between mental and somatic specialist care for this group of patients. Dimensions of the relationship and communication between clinician and patient are shown in primary care studies to be decisive for subsequent illness pathways, often creating adverse effects, but knowledge on clinical communication in specialist care is still scarce.

Methods

This study explores communicative challenges specific to clinical encounters between health professionals and adolescent patients in specialist care, as presented through interviews and focus group data with highly experienced specialists working in adolescent and child services at a Norwegian university hospital.

Results

The results are presented in a conceptual model describing the epistemological and methodological paradoxes inherent in the clinical uncertainty of MUS. Within these paradoxes, the professionals try to solve the dilemmas by being creative in their communication strategies; applying metaphors and other rhetorical devices to explain complex ideas; creating clinical prototypes as a way to explain symptoms and guide them in clinical action; relying on principles from patient-centered care involving empathy; and trying to balance expertise and humility.

Conclusion

The challenges in communication arise as a result of opposing discourses on biomedicine, family, health and adolescence that create dilemmas in everyday clinical work. By moving away from a positivist and biomedical framework towards an interpretive paradigm, where culturally derived and historically situated interpretations are used to understand the social life-world of the patient, one can create a more humane health service in accordance with ideals of patient-centered care.

Quantifying positive communication: Doctor's language and patient anxiety in primary care consultations

OBJECTIVE

Positive communication is advocated for physicians during consultations with patients presenting medically unexplained symptoms (MUS), but studies generally focus on what is said rather than how it is said. This study quantified language use differences of general practitioners (GPs), and assessed their relation to patient anxiety.

METHODS

Language use of 18 Dutch GPs during 82 consultations was compared for patients with MUS versus medically explained symptoms (MES). Message content (positive or negative) was differentiated from its directness (direct or indirect), and related to changes in patient's state anxiety (abbreviated State Trait Anxiety Inventory; STAI).

RESULTS

In total, 2590 clauses were identified. GPs approached patients with MES with relatively more direct (vs. indirect) positive and indirect (vs. direct) negative messages (OR 1.91, 95% CI 1.42-2.59). Anxiety of both patient groups increased when GPs used more direct (vs. indirect) negative messages (b = 0.67, 95% CI 0.07-1.27) CONCLUSIONS: GPs use different language depending on the content of messages for patients with MES, but not MUS. Direct negative messages relate to an increase in patient anxiety.

PRACTICE IMPLICATIONS

GPs could manage patient's state anxiety by expressing negative messages in an indirect rather than direct manner.

Managing patients' information in a community mental health team

Aims and Method

To explore current practice in offering patients copies of correspondence, we audited the documentation of 422 patients of a community mental health team.

Results

Discussion about copying letters was documented in 194 case notes (46%); older patients and those with medically unexplained physical symptoms were less likely to be offered copies. There were 159 patients (82%) that wanted to receive copies of letters; male gender was associated with declining this option. In 167 (87%) instances the professional completing the form was a psychiatrist.

Clinical Implications

Older patients need to be offered the opportunity to receive correspondence. Clinicians should record and substantiate their decision not to offer copies of letters to some patients. Professionals other than psychiatrists should be encouraged to discuss copying letters with patients.

Functional Somatic Syndrome: Assessment and Management

Functional somatic syndrome (FSS) occurs in as many as 30% of patients in general medical practice, but it is infrequently a topic of formal instruction. Many physicians feel uncomfortable with medically unexplained symptoms and are unfamiliar with how to assess or manage them. Traditional medical approaches can be ineffective and can contribute to iatrogenic or adverse physiologic effects in patients. Physicians treating patients with FSS should not only consider standard medical tests, but they should also try to gain a deeper behavioral understanding of the mind-body connections that underlie the presenting symptoms. Osteopathic physicians, with their emphasis on holistic patient care, are in a key position to treat patients with FSS. This review provides a brief recapitulation of the literature and illustrates key factors in the assessment and management of FSS.

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.

"Because everything changes that day; you don't do the routine": Alterations and activities chronically ill women undertake on days with health care provider appointments

OBJECTIVES

Research points to the importance of interactions with health care providers for chronically ill patients. Meanwhile, we know little about how visits to providers' offices are accommodated in these patients' lives. This analysis identifies the full scope of routine alterations and preparatory activities that require chronically will women's time and energy specifically on appointment days.

METHODS

55 semi-structured interviews were conducted with women with fibromyalgia syndrome living in Ontario, Canada. Interviews were transcribed verbatim and analyzed using the constant-comparative technique.

RESULTS

Two trajectories are identified: (1) alterations to daily routines on appointment days; and (2) activities to prepare for the provider-patient interaction. Factors such as wanting to minimize symptom exacerbation, desires to come across as informed patients, limited time afforded to interactions, and access to transportation explain why these particular routine alterations and preparatory activities were undertaken.

DISCUSSION

Findings demonstrate that the health care provider-patient interaction does not start or end in the space of the provider's office but is, rather, an event that is part of a larger process primarily focused on its successful negotiation. This suggests that the boundaries of the appointment need to be reconsidered, which holds implications for appointment-focused interventions aimed at chronically ill patients.

Medically Unexplained Symptoms: Barriers to Effective Treatment When Nothing Is the Matter

Patients with symptoms that elude medical explanation are a perennial challenge to practicing physicians of all disciplines. Articles appear virtually monthly advising physicians how to care for them. Efforts at postgraduate education have attempted to ameliorate the situation but have shown limited or disappointing results at best. Physicians continue either to avoid these patients or to resort to a "seat-of-the-pants" approach to management. Literature on patients with medically unexplained symptoms, along with extensive experience consulting with primary care physicians, suggests that it is not primarily lack of physician skills but rather a series of barriers to adequate care that may account for suboptimal management. Barriers to implementation of effective care reside in the nature of medical education, the doctor-patient relationship, heterogeneity of symptoms and labels, changes in the health care system, and other variables. These impediments are considered here, with suggested potential remedies, in the conviction that the proper care of patients with medically unexplained symptoms can, among other things, bring satisfaction to both the patient and the physician, and help to reduce ineffective health resource utilization.

Causal explanatory pluralism and medically unexplained physical symptoms

In this paper, we propose a methodology for investigating medically unexplained physical symptoms (MUPSs). These symptoms are common in both primary and specialist medical practices, but are poorly understood. Currently, MUPSs are diagnosed via non-explanatory labels. However, we show that explanatory diagnoses are preferable to non-explanatory syndromic diagnoses because they bring both epistemic and therapeutic benefits to patients and their providers. Thus, we advocate a methodology of causal explanatory pluralism in the diagnostic workup and clinical management of MUPSs.

Psychiatric assessment of mood instability: qualitative study of patient experience

BACKGROUND

Mood instability is a common reason for psychiatric referral. Very little is known about how patients with unstable mood experience assessment and diagnosis.

AIMS

To investigate the experiences of assessment and diagnosis among patients with mood instability and to suggest improvements to this process.

METHOD

Qualitative study, gathering data through individual interviews with 28 people experiencing mood instability and receiving a psychiatric assessment in secondary care.

RESULTS

Participants described the importance of receiving an explanation for their symptoms; the value of a good interpersonal relationship with their clinician(s); being listened to and acknowledged; and being involved in and informed about clinical decisions. These needs were not, however, consistently met. Receiving a psychiatric diagnosis, including a diagnosis of bipolar disorder or borderline personality disorder, evoked both positive and negative responses among participants, relating to stigma, personal understanding and responsibility, prognosis and treatment.

CONCLUSIONS

Patients with mood instability seek explanation for their symptoms and difficulties, empathetic care and consistent support as much as cure. Clinicians may incorrectly assume what patients' attitudes towards diagnosis are, a mismatch which may hamper the development of a strong therapeutic relationship. Clear, patient-centred communication, which acknowledges the patient's experience, may result in greater patient engagement and satisfaction.

Misinformation increases symptom reporting: a test - retest study

Objectives

We examined whether misleading information (i.e. misinformation) may promote symptom reporting in non-clinical participants.

Design

A test–retest study in which we collected baseline data about participants' psychological symptoms and then misinformed them that they had rated two target symptoms relatively highly. During an interview, we determined whether participants would notice this misinformation and at direct and one-week follow-up, we evaluated whether the misinformation would exacerbate retest measures of the same symptoms.

Setting

A psychological laboratory.

Participants

A total of 78 undergraduate students.

Main outcome measures

Participants' scores on a widely used self-report measure of psychological symptoms.

Results

We found that most participants (63%) were blind to the discrepancies between their original symptom ratings and the upgraded scores they were misinformed with. Furthermore, at the one-week follow-up retest, blind participants revised their symptom ratings in the direction of the misinformation (i.e. they increased their ratings of these symptoms).

Conclusion

Introspective monitoring of common psychological symptoms is poor and this creates an opportunity for misinformation and symptom escalation. Our finding bears relevance to theories about the iatrogenic amplification of medically unexplained symptoms.

Psychosomatic symptoms and the 'group mind'

OBJECTIVES

In this work, we propose a model, designed to understand mental symptoms and adapted for the analysis of psychosomatic symptoms, to be used as a tool to represent group phenomena, named the 'group mind'.

DESIGN

A revision of the relevant literature on the concept of 'group mind' and psychosomatics, and the presentation of the Cambridge model.

METHODS

We describe how unformatted experiences can appear as somatization, and how this process can be corrected via mental representations. Group dynamics can function creating these representations and thus contribute to solving psychosomatic symptoms. We refer to W. R. Bion's concepts, mainly the ones on proto-thoughts and the proto-mental system, comparing them to the proposed model and giving a foundation to this conceptual representation. We illustrate with four cases of clinical interaction.

CONCLUSIONS

Psychotherapeutic groups are privileged places to comprehend and transform psychosomatic symptoms. The Cambridge model allows a representation of these processes. Further studies are necessary to assess its validity, test its adequacy, and expand its possibilities.

Diagnosing somatisation disorder (P75) in routine general practice using the International Classification of Primary Care

OBJECTIVE

(i) To analyze general practitioners' diagnosis of somatisation disorder (P75) using the International Classification of Primary Care (ICPC)-2-E in routine general practice. (ii) To validate the distinctiveness of the ICD-10 to ICPC-2 conversion rule which maps ICD-10 dissociative/conversion disorder (F44) as well as half of the somatoform categories (F45.0-2) to P75 and codes the other half of these disorders (F45.3-9), including autonomic organ dysfunctions and pain syndromes, as symptom diagnoses plus a psychosocial code in a multiaxial manner.

METHODS

Cross-sectional analysis of routine data from a German research database comprising the electronic patient records of 32 general practitioners from 22 practices. For each P75 patient, control subjects matched for age, gender, and practice were selected from the 2007 yearly contact group (YCG) without a P75 diagnosis using a propensity-score algorithm that resulted in eight controls per P75 patient.

RESULTS

Of the 49,423 patients in the YCG, P75 was diagnosed in 0.6% (302) and F45.3-9 in 1.8% (883) of cases; overall, somatisation syndromes were diagnosed in 2.4% of patients. The P75 coding pattern coincided with typical characteristics of severe, persistent medically unexplained symptoms (MUS). F45.3-9 was found to indicate moderate MUS that otherwise showed little clinical difference from P75. Pain syndromes exhibited an unspecific coding pattern. Mild and moderate MUS were predominantly recorded as symptom diagnoses. Psychosocial codes were rarely documented.

CONCLUSIONS

ICPC-2 P75 was mainly diagnosed in cases of severe MUS. Multiaxial coding appears to be too complicated for routine primary care. Instead of splitting P75 and F45.3-9 diagnoses, it is proposed that the whole MUS spectrum should be conceptualized as a continuum model comprising categorizations of uncomplicated (mild) and complicated (moderate and severe) courses. Psychosocial factors require more attention.

A Biopsychosocial Model of Sickness and Disability

Despite improvements in objective measures of impairment, health, and working conditions, long-term incapacity and ill-health retirement are major problems in all western societies. This article explores three models that address disability: the medical, social, and biopsychosocial models. The medical model identifies the sequence from disease that causes an impairment to a disability that leads to incapacity; this model works best when identifiable pathology permits objective diagnosis and assessment but is inappropriate for many common health problems, particularly those that are subjective or when treatment is symptomatic and often ineffective. The social model is widely accepted as the basis for social inclusion and antidiscrimination policies but cannot be operationalized as the basis for individual entitlement for incapacity benefits. The biopsychosocial model attempts to tack account of biological, psychological, and social dimensions of health and is reflected in the International Classification of Functioning, Disability, and Health (ICF), which is the contemporary model of disablement used in the AMA Guides to the Evaluation of Permanent Impairment (AMA Guides), Sixth Edition. Powerful links exist among poor health, disability, social and regional disadvantage, worklessness, and poverty. Vocational rehabilitation, in the biopsychosocial model, reverses the question of why people develop long-term incapacity and instead asks why people with common health problems do not recover as expected. The answer involves addressing the biopsychosocial obstacles that delay or prevent expected recovery and requires a fundamental cultural shift in how we perceive and manage common health problems.

Primary care consultations about medically unexplained symptoms: patient presentations and doctor responses that influence the probability of somatic intervention

OBJECTIVE

In primary care, many consultations about physical symptoms that the doctor thinks are not explained by physical disease nevertheless lead to somatic interventions. Our objective was to test the predictions that somatic intervention becomes more likely a) when doctors provide simple reassurance rather than detailed symptom explanations and do not help patients discuss psychosocial problems and b) when patients try to engage doctors by extending their symptom presentation.

METHODS

Consultations of 420 patients presenting physical symptoms that the doctor considered unexplained by physical disease were audio-recorded, transcribed, and coded. Analysis modeled the probability of somatic intervention as a function of the quantity of specific types of speech by patients (symptomatic and psychosocial presentations) and doctors (normalization, physical explanations, psychosocial discussion).

RESULTS

Somatic intervention was associated with the duration of consultation. Controlling for duration, it was, as predicted, associated positively with symptom presentations and inversely with patients' and doctors' psychosocial talk. The relationship with doctors' psychosocial talk was accounted for by patients' psychosocial talk. Contrary to predictions, doctors' normalization was inversely associated with somatic intervention and physical explanations had no effect.

CONCLUSION

Somatic intervention did not result from the demands of patients. Instead, it became more likely as patients complained about their symptoms. Facilitating patients' psychosocial talk has the potential to divert consultations about medically unexplained symptoms from somatic interventions. To understand why such consultations often lead to somatic interventions, we must understand why patients progressively extend their symptom presentations and why doctors, in turn, apparently respond to this by providing somatic intervention.

Why do general practitioners decline training to improve management of medically unexplained symptoms?

BACKGROUND

General practitioners' (GPs) communication with patients presenting medically unexplained symptoms (MUS) has the potential to somatize patients' problems and intensify dependence on medical care. Several reports indicate that GPs have negative attitudes about patients with MUS. If these attitudes deter participation in training or other methods to improve communication, practitioners who most need help will not receive it.

OBJECTIVE

To identify how GPs' attitudes to patients with MUS might inhibit their participation with training to improve management.

DESIGN

Qualitative study.

PARTICIPANTS

GPs (N = 33) who had declined or accepted training in reattribution techniques in the context of a research trial.

APPROACH

GPs were interviewed and their accounts analysed qualitatively.

RESULTS

Although attitudes that devalued patients with MUS were common in practitioners who had declined training, these coexisted, in the same practitioners, with evidence of intuitive and elaborate psychological work with these patients. However, these practitioners devalued their psychological skills. GPs who had accepted training also described working psychologically with MUS but devalued neither patients with MUS nor their own psychological skills.

CONCLUSIONS

GPs' attitudes that suggested disengagement from patients with MUS belied their pursuit of psychological objectives. We therefore suggest that, whereas negative attitudes to patients have previously been regarded as the main barrier to involvement in measures to improve patient management, GPs devaluing of their own psychological skills with these patients may be more important.

Somatization disorder and cancer: a case history and review

Cancer pain generally has a physical cause exacerbated to varying degrees by psychological, social, and spiritual factors. This article describes the case history of a cancer patient with severe pain for which no physical cause could be found, who was subsequently found to have a history of somatization disorder. There follows a review of the literature, with specific reference to the difficulties of managing somatization in the context of cancer.

The potentially somatizing effect of clinical consultation

Many patients who present physical symptoms that their doctors cannot explain by physical disease have persisting symptoms and impairment. An influential view has been that such symptoms are the somatization of emotional distress, but there has also been concern that medical practice contributes to shaping these presentations. Analysis of patients' accounts indicate that they approach these consultations with a sense of being the expert on the nature and reality of their symptoms and, in primary care at least, they seek convincing explanations, engagement, and support. They often describe doctors as doubting that their symptoms are real and as not taking their symptoms seriously. Observational research has demonstrated that patients presenting idiopathic symptoms in primary care generally provide cues to their need for explanation or to psychosocial difficulties. Their doctors tend to provide simple reassurance rather than detailed explanations, and often disregard psychosocial cues. Patients seem to intensify their presentation in consequence, elaborating and extending their accounts of their symptoms, perhaps in the effort to engage their doctors and demonstrate the reality of their symptoms. When doctors propose physical investigation and treatment in response to such escalating presentation, they thereby inadvertently somatize patients' psychological presentation. Consultations, therefore, have elements of contest, whereby patients seek engagement from doctors who seek to disengage. Although provision of a medical label, such as a functional diagnosis, can legitimize patients' complaints and avoid contest, this is at the risk of indicating that medicine can take responsibility for managing the symptoms. More collaborative relationships rely on doctors recognizing patients' authority in knowing about their symptoms, and providing tangible explanations that make sense to the patient and allow them to tolerate or manage the symptoms. Researchers need to study how doctors can best achieve these aims within routine consultations.

Incidence of fatigue symptoms and diagnoses presenting in UK primary care from 1990 to 2001

Little is known about whether the incidence of symptoms of fatigue presented in primary care, and the consequent diagnoses made, change over time. The UK General Practice Research Database was used to investigate the annual incidence of both fatigue symptoms and diagnoses recorded in UK primary care from 1990 to 2001. The overall incidence of all fatigue diagnoses decreased from 87 per 100 000 patients in 1990 to 49 in 2001, a reduction of 44%, while postviral fatigue syndromes decreased from 81% of all fatigue diagnoses in 1990 to 60% in 2001. Chronic fatigue syndrome (CFS) and myalgic encephalomyelitis (ME) together increased from 9% to 26% of all fatigue diagnoses. The incidence of fibromyalgia increased from less than 1 per 100 000 to 35 per 100 000. In contrast, there was no consistent change in the incidence of all recorded symptoms of fatigue, with an average of 1503 per 100 000, equivalent to 1.5% per year. CFS/ME and fibromyalgia were rarely diagnosed in children and were uncommon in the elderly. All symptoms and diagnoses were more common in females than in males. The overall incidence of fatigue diagnoses in general has fallen, but the incidence rates of the specific diagnoses of CFS/ME and fibromyalgia have risen, against a background of little change in symptom reporting. This is likely to reflect fashions in diagnostic labelling rather than true changes in incidence.
