Patients' perceptions of medical care in chronic fatigue syndrome.

This study investigated perceptions of medical care among patients with chronic fatigue syndrome (CFS) referred to a specialist clinic. Sixty-eight patients completed a questionnaire survey on their overall satisfaction with medical care received since the onset of their illness, and their views on specific aspects of care. Two-thirds of patients were dissatisfied with the quality of medical care received. Dissatisfied patients were significantly more likely to describe delay, dispute or confusion over diagnosis; to have received and rejected a psychiatric diagnosis; to perceive doctors as dismissive, skeptical or not knowledgeable about CFS and to feel that the advice given was inadequate or conflicting. Satisfied patients were significantly more likely to perceive doctors as caring, supportive and interested in their illness; to state that they did not expect their doctors to cure CFS and to perceive their GP or hospital doctor as the source of greatest help during their illness. Many patients were critical of the paucity of treatment, but this was not associated with overall satisfaction. The findings suggest that medical care was evaluated less on the ability of doctors to treat CFS, and more on their interpersonal and informational skills. Dissatisfaction with these factors is likely to impede the development of a therapeutic doctor-patient alliance, which is central to the effective management of CFS. The findings suggest a need for better communication and better education of doctors in the diagnosis and management of CFS.

Diagnosis of psychiatric disorder in clinical evaluation of chronic fatigue syndrome.

The overlap of symptoms in chronic fatigue syndrome (CFS) and psychiatric disorders such as depression can complicate diagnosis. Patients often complain that they are wrongly given a psychiatric label. We compared psychiatric diagnoses made by general practitioners and hospital doctors with diagnoses established according to research diagnostic criteria. 68 CFS patients referred to a hospital fatigue clinic were assessed, and psychiatric diagnoses were established by use of a standardized interview schedule designed to provide current and lifetime diagnoses. These were compared with psychiatric diagnoses previously given to patients. Of the 31 patients who had previously received a psychiatric diagnosis 21 (68%) had been misdiagnosed: in most cases there was no evidence of any past or current psychiatric disorder. Of the 37 patients who had not previously received a psychiatric diagnosis 13 (35%) had a treatable psychiatric disorder in addition to CFS. These findings highlight the difficulties of routine clinical evaluation of psychiatric disorder in CFS patients. We advise doctors to focus on subtle features that discriminate between disorders and to use a brief screening instrument such as the Hospital Anxiety and Depression Scale.

Illness beliefs and treatment outcome in chronic fatigue syndrome.

Longitudinal studies have shown that physical illness attributions are associated with poor prognosis in chronic fatigue syndrome (CFS). Speculation exists over whether such attributions influence treatment outcome. This study reports the effect of illness beliefs on outcome in a randomized controlled trial of cognitive-behavior therapy versus relaxation. Causal attributions and beliefs about exercise, activity, and rest were recorded before and after treatment in 60 CFS patients recruited to the trial. Physical illness attributions were widespread, did not change with treatment, and were not associated with poor outcome in either the cognitive-behavior therapy group or the control group. Beliefs about avoidance of exercise and activity changed in the cognitive behavior therapy group, but not in the control group. This change was associated with improved outcome. These findings suggest that physical illness attributions are less important in determining outcome (at least in treatment studies) than has been previously thought. In this study, good outcome is associated with change in avoidance behavior, and related beliefs, rather than causal attributions.

Clinical improvement in chronic fatigue syndrome is not associated with lymphocyte subsets of function or activation.

The relationship between markers of immune function and chronic fatigue syndrome (CFS) is controversial. To examine the relationship directly, 43 subjects with CFS entering a randomized controlled trial of a nonpharmacological treatment for CFS gave samples for immunological analysis before and after treatment. Percentage levels of total CD3+ T cells, CD4 T cells, CD8 T cells, and activated subsets did not differ between CFS subjects and controls. Naive (CD45RA+ RO-) and memory (CD45RA- RO+) T cells did not differ between subjects and controls. Natural killer cells (CD16+/CD56+/CD3-) were significantly increased in CFS patients compared to controls, as was the percentage of CD11b+ CD8 cells. There were no correlations between any immune variable and measures of clinical status, with the exception of a weak correlation between total CD4 T cells and fatigue. There was a positive correlation between memory CD4 and CD8 T cells and depression scores and a negative correlation between naive CD4 T cells and depression. No immune measures changed during the course of the study, and there was no link between clinical improvement as a result of the treatment program and immune status. Immune measures did not predict response or lack of response to treatment. In conclusion, we have been unable to replicate previous findings of immune activation in CFS and unable to find any important associations between clinical status, treatment response, and immunological status.

Cognitive behavior therapy for chronic fatigue syndrome: a randomized controlled trial.

OBJECTIVE: Cognitive behavior therapy for chronic fatigue syndrome was compared with relaxation in a randomized controlled trial. METHODS: Sixty patients with chronic fatigue syndrome were randomly assigned to 13 sessions of either cognitive behavior therapy (graded activity and cognitive restructuring) or relaxation. Outcome was evaluated by using measures of functional impairment, fatigue, mood, and global improvement. RESULTS: Treatment was completed by 53 patients. Functional impairment and fatigue improved more in the group that received cognitive behavior therapy. At final follow-up, 70% of the completers in the cognitive behavior therapy group achieved good outcomes (substantial improvement in physical functioning) compared with 19% of those in the relaxation group who completed treatment. CONCLUSIONS: Cognitive behavior therapy was more effective than a relaxation control in the management of patients with chronic fatigue syndrome. Improvements were sustained over 6 months of follow-up.

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

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.

Does imagined exposure to the consequences of not ritualising enhance live exposure for OCD? A controlled study. I. Main outcome.

BACKGROUND: This randomised controlled study tested whether adding imagined to live exposure plus ritual prevention would enhance gains in obsessive-compulsive disorder (OCD). METHOD: Out-patients with OCD were randomly allocated to either have nine sessions of daily live self-exposure and ritual prevention to external cues alone (Ex) (n = 23) or to have, in addition to Ex, daily self-exposure to the imagined internal cues of the consequences of not ritualising (group Exi) (n = 23). All patients had the same sessional exposure time of 1 h 30 min (Exi 1 h live, 30 min imagined; Ex 1 h 30 min live), and had to practise either Exi or Ex daily for the same duration and to keep diaries of that self-exposure homework throughout treatment. Patients were followed up to week 32. Outcome measures were YBOCS for rituals and obsessions, compulsion checklist, target rituals and obsession, general anxiety, depression (Beck, Hamilton), work and social disability, clinical global impression (CGI). RESULTS: At weeks 4, 9, 20 and 32 the two groups improved similarly with no significant difference between them, neither for washers nor for checkers. Imagined exposure was more difficult to do than live exposure and there were more drop-outs. CONCLUSIONS: Daily imaged exposure to internal cues did not enhance exposure to external cues. Perhaps longer imagined exposure would have been more enhancing.

Gender differences in obsessive compulsive disorder.

We investigated gender differences in 219 patients with obsessive compulsive disorder consecutively referred to a centre specialising in the behavioural treatment of anxiety disorders. Females had a later mean onset-age, and were more likely to be married and to have children; they were also marginally more likely to have a past history of an eating disorder or depression, while males were more likely to have a history of anxious or meticulous personality traits. Family loading for psychiatric disorders did not differ significantly between the sexes. The results are discussed in the context of the epidemiological literature on gender differences in OCD.

Obsessive-compulsive disorder: prediction of outcome from behavioural psychotherapy.

Prediction of outcome after behavioural psychotherapy was determined in 178 outpatients with obsessive-compulsive disorder. For women (n = 103), factors significantly associated with good outcome included paid employment at time of assessment, having a co-therapist and low initial ratings on global phobia, work and home activity impairment and the compulsion checklist. In men, the only factor to approach statistical significance as a predictor of outcome was solitary abode, associated with "less improved" status.

Hyperventilation and chronic fatigue syndrome.

We studied the link between chronic fatigue syndrome (CFS) and hyperventilation in 31 consecutive attenders at a chronic fatigue clinic (19 females, 12 males) who fulfilled criteria for CFS based on both Oxford and Joint CDC/NIH criteria. All experienced profound fatigue and fatigability associated with minimal exertion, in 66% developing after an infective episode. Alternative causes of fatigue were excluded. Hyperventilation was studied during a 43-min protocol in which end-tidal PCO2 (PETCO2) was measured non-invasively by capnograph or mass spectrometer via a fine catheter taped in a nostril at rest, during and after exercise (10-50 W) and for 10 min during recovery from voluntary overbreathing to approximately 2.7 kPa (20 mmHg). PETCO2 < 4 kPa (30 mmHg) at rest, during or after exercise, or at 5 min after the end of voluntary overbreathing, suggested either hyperventilation or a tendency to hyperventilate. Most patients were able voluntarily to overbreathe, but not all were able to exercise. Twenty-two patients (71%) had no evidence of hyperventilation during any aspect of the test. Only four patients had unequivocal hyperventilation, in one associated with asthma and in three with panic. Only one patient with severe functional disability and agoraphobia had hyperventilation with no other obvious cause. A further five patients had borderline hyperventilation, in which PETCO2 was < 4 kPa (30 mmHg) for no more than 2 min, when we would have expected it to be normal. There was no association between level of functional impairment and degree of hyperventilation. There is only a weak association between hyperventilation and chronic fatigue syndrome.(ABSTRACT TRUNCATED AT 250 WORDS)
