Unexplained fatigue syndromes in a multinational primary care sample: specificity of definition and prevalence and distinctiveness from depression and generalized anxiety

Abstract:

OBJECTIVE: The authors investigated whether narrow definitions of unexplained fatigue syndromes that require additional minor somatic symptoms are more strongly associated with psychiatric morbidity than wider ones.

METHOD: This was a secondary analysis of the World Health Organization Collaborative Project on Psychological Problems in General Health Care. A total of 5,438 primary care patients from 14 countries were assessed with the Composite International Diagnostic Interview.

RESULTS: The prevalence of fatigue syndromes fell from 7.99 to 1.69 as somatic criteria were added. Patients with depression or anxiety were more likely to report unexplained fatigue, but this association was stronger for definitions of unexplained fatigue with more somatic criteria.

CONCLUSIONS: Definitions of unexplained fatigue syndromes that require more somatic criteria selected more patients with psychiatric disorders in this culturally diverse sample. These findings might have implications for the revision of existing international diagnostic criteria for neurasthenia or chronic fatigue syndrome.

Chronic fatigue in general practice: is counselling as good as cognitive behaviour therapy? A UK randomised trial

Abstract:

BACKGROUND: Fatigue is a common symptom for which patients consult their doctors in primary care. With usual medical management the majority of patients report that their symptoms persist and become chronic. There is little evidence for the effectiveness of any fatigue management in primary care.

AIM: To compare the effectiveness of cognitive behaviour therapy (CBT) with counselling for patients with chronic fatigue and to describe satisfaction with care.

DESIGN OF STUDY: Randomised trial with parallel group design.

SETTING: Ten general practices located in London and the South Thames region of the United Kingdom recruited patients to the trial between 1996 and 1998. Patients came from a wide range of socioeconomic backgrounds and lived in urban, suburban, and rural areas.

METHOD: Data were collected before randomisation, after treatment, and six months later. Patients were offered six sessions of up to one hour each of either CBT or counselling. Outcomes include: self-report of fatigue symptoms six months later, anxiety and depression, symptom attributions, social adjustment and patients’ satisfaction with care.

RESULTS: One hundred and sixty patients with chronic fatigue entered the trial, 45 (28%) met research criteria for chronic fatigue syndrome; 129 completed follow-up. All patients met Chalder et al’s standard criteria for fatigue. Mean fatigue scores were 23 on entry (at baseline) and 15 at six months’ follow-up. Sixty-one (47%) patients no longer met standard criteria for fatigue after six months. There was no significant difference in effect between the two therapies on fatigue (1.04 [95% CI = -1.7 to 3.7]), anxiety and depression or social adjustment outcomes for all patients and for the subgroup with chronic fatigue syndrome. Use of antidepressants and consultations with the doctor decreased after therapy but there were no differences between groups.

CONCLUSION: Counselling and CBT were equivalent in effect for patients with chronic fatigue in primary care. The choice between therapies can therefore depend on other considerations, such as cost and accessibility.

Psychiatric morbidity and illness experience of primary care patients with chronic fatigue in Hong Kong

Abstract:

OBJECTIVE: The authors’ goal was to examine the prevalence and experience of psychiatric morbidity among primary care patients with chronic fatigue in Hong Kong.

METHOD: One hundred adult patients with medically unexplained fatigue for 6 or more months were assessed with the Explanatory Model Interview Catalogue, psychopathological rating scales, and an enhanced version of the Structured Clinical Interview for DSM-III-R.

RESULTS: The lifetime prevalence of DSM-III-R depressive and anxiety disorders was 54%. Current depressive and anxiety disorders were identified in 28 patients, who exhibited more psychopathology and functional impairment than other patients. Thirty-three patients had somatoform pain disorder, and 30 had undifferentiated somatoform disorder, but most of them could also be diagnosed as having shenjing shuairuo (weakness of nerves) and, to a lesser extent, ICD-10 neurasthenia. Chronic fatigue syndrome diagnosed according to the 1988 Centers for Disease Control criteria was rare (3%) and atypical. Generally, patients mentioned fatigue if asked, but pains (36%), insomnia (20%), and worries (13%) were the most troublesome symptoms. Most patients attributed illness onset to psychosocial sources.

CONCLUSIONS: Psychiatric morbidity was common among primary care patients with chronic fatigue. Subthreshold psychiatric morbidity was very common and was more validly represented by the disease construct of shenjing shuairuo or neurasthenia than somatoform disorder.

Use of formal and informal care among people with prolonged fatigue: a review of the literature

Abstract:

Prolonged fatigue is a common symptom in the community and a common complaint in GPs’ surgeries. The current consensus is that prolonged fatigue is most appropriately managed within primary care but that quality of care is patchy. Diagnosis is difficult and there is no conclusive evidence about effective treatment. This can lead to confusion and controversy among lay people and health professionals alike. Although the value of a positive doctor-patient relationship is emphasized, general practice consultations are frequently experienced as difficult by both parties. Moreover, little is known about how people access other sources of care and information about prolonged fatigue, such as alternative medicine, self-help groups, lay others, and self care, in conjunction with or as an alternative to care from health professionals. This paper reviews the literature on the nature and extent of the problem prolonged fatigue represents for primary care, and on the use of formal and informal care for prolonged fatigue.

A naturalistic study of the chronic fatigue syndrome among women in primary care

Abstract:

Chronic fatigue syndrome (CFS), a controversial illness without clear etiology, causes profound debilitation in its sufferers. This study explored subjects’ perceptions of the variables that mediated the course of their illness and identified coping strategies in 15 women with CFS referred from the practice of a primary care physician.

Exploratory semistructured interviews were adapted from Kleinman’s Illness Narratives. Four instruments were used: the Beck Depression Inventory, the Sickness Impact Profile, a modified Karnofsky scale, and the Defense Mechanism Rating Scale. Of the 15 women, 60% reported improvement and/or recovery at the time of the interview.

Improvement was associated with social support and lower levels of depressive symptoms. Health status was influenced by how subjects perceived their illness, their future, and the doctor’s prognosis; and by the physician’s early diagnosis, validation of the CFS, and intensive medical follow-up. Obsessional and healthy neurotic defense levels predominated, which differs from historical comparison groups with dysthymia and panic disorder.

Psychological adaptation to CFS is similar to adaptive coping in other chronic illnesses: subjective perceptions of health status can predict functional status. Physician validation is particularly important given the controversial status of CFS. Maintaining relationships with others–doctor, work, family, and group/spiritual activities reflected healthy coping strategies that promoted hope and attitudinal shifts.

The finding of a mixture of neurotic and healthy defenses and a low proportion of defenses associated with personality disorders has not been previously reported in the CFS literature and warrants further investigation.

Chronic debilitating fatigue in Irish general practice: a survey of general practitioners’ experience

Abstract:

BACKGROUND: Doctors are called upon to treat chronic debilitating fatigue without the help of a protocol of care.

AIMS: To estimate the incidence of chronic debilitating fatigue in Irish general practice, to obtain information on management strategy and outcome, to explore the attitudes of practitioners (GPs) towards the concept of a chronic fatigue syndrome (CFS), and to recruit practitioners to a prospective study of chronic fatigue in primary care.

METHOD: A total of 200 names were selected from the database of the Irish College of General Practitioners (ICGP); 164 of these were eligible for the study.

RESULTS: Altogether, 118 questionnaires were returned (72%). Ninety-two (78%) responders identified cases of chronic fatigue, giving an estimated 2.1 cases per practice and an incidence of 1 per 1000 population. All social classes were represented, with a male to female ratio of 1:2. Eleven disparate approaches to treatment were advocated. Many (38%) were dissatisfied with the quality of care delivered, and 45% seldom or hardly ever referred cases for specialist opinion. The majority (58%) accepted CFS as a distinct entity, 34% were undecided, and 8% rejected it. Forty-two (35%) GPs volunteered for a prospective study.

CONCLUSION: Chronic fatigue is found in Irish general practice among patients of both sexes and all social classes. Doctors differ considerably in their management of patients and are dissatisfied with the quality of care they deliver. Many cases are not referred for specialist opinion. A prospective database is required to accurately assess the scale of this public health problem and to develop a protocol of care.

The prevalence and morbidity of chronic fatigue and chronic fatigue syndrome: a prospective primary care study

Abstract:

OBJECTIVES: This study examined the prevalence and public health impact of chronic fatigue and chronic  fatigue syndrome in primary care patients in England.

METHODS: There were 2376 subjects, aged 18 through 45 years. Of 214 subjects who fulfilled criteria for chronic fatigue, 185 (86%) were interviewed in the case-control study. Measures included chronic fatigue, psychological morbidity, depression, anxiety, somatic symptoms, symptoms of chronic fatigue syndrome, functional impairment, and psychiatric disorder.

RESULTS: The point prevalence of chronic fatigue was 11.3%, falling to 4.1% if comorbid psychological disorders were excluded. The point prevalence of chronic fatigue syndrome was 2.6%, falling to 0.5% if comorbid psychological disorders were excluded. Rates did not vary by social class. After adjustment for psychological disorder, being female was modestly associated with chronic fatigue. Functional impairment was profound and was associated with psychological disorder.

CONCLUSIONS: Both chronic fatigue and chronic fatigue syndrome are common in primary care patients and represent a considerable public health burden. Selection bias may account for previous suggestions of a link with higher socioeconomic status.

Chronic fatigue syndrome: an update for clinicians in primary care

Abstract:

Cases of long-standing (6 months or longer) fatigue that are not explained by an existing medical or psychiatric diagnosis are referred to as chronic fatigue syndrome (CFS). CFS is a condition of unknown etiology that presents with a complex array of symptoms in patients with diverse health histories. A diagnosis of CFS is largely dependent upon ruling out other organic and psychologic causes of fatigue. CFS can present the clinician with a unique set of challenges in terms of diagnosis and treatment. A review of recent research suggests that the management of CFS requires an individualized approach for each patient. An historic overview of the condition is presented along with current theories of causation, diagnosis considerations, symptom management, and health promotion strategies.

Psychological symptoms, somatic symptoms, and psychiatric disorder in chronic fatigue and chronic fatigue syndrome: a prospective study in the primary care setting

Abstract:

OBJECTIVE: This study assessed relationships among psychological symptoms, past and current psychiatric disorder, functional impairment, somatic symptoms, chronic fatigue, and chronic fatigue syndrome.

METHOD: A prospective cohort study was followed by a nested case-control study. The subjects, aged 18-45 years, had been in primary care for either clinical viral infections or a range of other problems. Questionnaire measures of fatigue and psychological symptoms were completed by 1,985 subjects 6 months later; 214 subjects with chronic fatigue were then compared with 214 matched subjects without fatigue. Assessments were made with questionnaires, interviews, and medical records of fatigue, somatic symptoms, psychiatric disorder, and functional impairment.

RESULTS: Subjects with chronic fatigue were at greater risk than those without chronic fatigue for current psychiatric disorder assessed by standardized interview (60% versus 19%) or by questionnaire (71% versus 31%). Chronic fatigue subjects were more likely to have received psychotropic medication or experienced psychiatric disorder in the past. There was a trend for previous psychiatric disorder to be associated with comorbid rather than noncomorbid chronic fatigue. Most subjects with chronic fatigue syndrome also had current psychiatric disorder when assessed by interview (75%) or questionnaire (78%). Both the prevalence and incidence of chronic fatigue syndrome were associated with measures of previous psychiatric disorder. The number of symptoms suggested as characteristics of chronic fatigue syndrome was closely related to the total number of somatic symptoms and to measures of psychiatric disorder. Only postexertion malaise, muscle weakness, and myalgia were significantly more likely to be observed in chronic fatigue syndrome than in chronic fatigue.

CONCLUSIONS: Most subjects with chronic fatigue or chronic fatigue syndrome in primary care also meet criteria for a current psychiatric disorder. Both chronic fatigue and chronic fatigue syndrome are associated with previous psychiatric disorder, partly explained by high rates of current psychiatric disorder. The symptoms thought to represent a specific process in chronic fatigue syndrome may be related to the joint experience of somatic and psychological distress.

A comparison of the characteristics of chronic fatigue syndrome in primary and tertiary care

Abstract:

BACKGROUND: To evaluated the characteristics of Chronic Fatigue Syndrome (CFS) in primary and tertiary care.

METHOD: A comparison of subjects fulfilling criteria for CFS, identified as part of a prospective cohort study in primary care, compared to 79 adults fulfilling the same criteria referred for treatment to a specialist CFS clinic.

RESULTS: Hospital cases were more likely to belong to upper socio-economic groups, and to have physical illness attributions. They had higher levels of fatigue and more somatic symptoms, and were more impaired functionally, but had less overt psychological morbidity. Women were over-represented in both primary care and hospital groups. Nearly half of those referred to a specialist clinic did not fulfil operational criteria for CFS.

CONCLUSION:The high rates of psychiatric morbidity and female excess that characterise CFS in specialist settings are not due to selection bias. On the other hand higher social class and physical illness attributions may be the result of selection bias and not intrinsic to CFS.
