Multiple somatic symptoms predict impaired health status in functional somatic syndromes.

BACKGROUND: The relationship between functional somatic syndromes and multiple somatic symptoms is unclear. PURPOSE: We assessed whether the number of somatic symptoms is a predictor of health status in three functional somatic syndromes (FSS). METHODS: In a population-based study of 990 UK adults we assessed chronic widespread pain (CWP), chronic fatigue (CF) and irritable bowel syndrome (IBS) by questionnaire and medical record data. We assessed health status (Short Form 12 and EQ-5D), number of somatic symptoms (Somatic Symptom Inventory) and anxiety/depression (Hospital Anxiety and Depression Scale) both at baseline and at follow-up 1 year later. RESULTS: The proportion of people with an FSS who also have multiple somatic symptoms (52-55 %) was similar in the three functional syndromes. The presence of multiple somatic symptoms was associated with more impaired health status both at baseline and at follow-up. This finding was not explained by severity of FSS. In the absence of multiple somatic symptoms, the health status of the FSS was fair or good. In multiple regression analysis, the number of somatic symptoms, the presence of a functional syndrome (CWP or CF) and anxiety/depression were predictors of EQ-5D thermometer at follow-up after adjustment for confounders. CONCLUSIONS: Multiple somatic symptoms in people with an FSS are associated with impaired health status and this cannot be explained by more severe functional syndrome or the presence of anxiety and depression.

A prospective study of social difficulties, acculturation and persistent depression in Pakistani women living in the UK.

BACKGROUND: The reasons for the high prevalence of depressive disorders in women of Pakistani origin living in the UK are not clear. The aim of this study was to determine the relative importance of life events, chronic social difficulties and acculturation in a population-based sample of British Pakistani women. METHOD: A cross-sectional and prospective cohort study of 18- to 65-year-old Pakistani women in UK was carried out. The Schedule for Clinical Assessment in Neuropsychiatry for diagnosis, the Life Events and Difficulties Schedule for social stress and an acculturation questionnaire were used. RESULTS: Depressive disorder at baseline was associated with older age, social isolation and marked difficulties involving health and close relationships. Depressive disorder at follow-up was associated with severity of depression at baseline, difficulties in close relationships and two aspects of acculturation, especially less acculturation in relation to use of the English language. CONCLUSIONS: Lack of acculturation, especially less familiarity with the English language, is an independent predictor of persistence of depression in Pakistani women in UK. This needs to be taken into consideration when planning treatment, which also needs to address the personal difficulties associated with persistent depression. The implication of this work is that women of Pakistani origin with depression should be encouraged to receive help in the use of English as one part of treatment that may prevent relapse.

A prospective study of psychological distress among mothers of children admitted to a nutritional rehabilitation unit in Malawi.

OBJECTIVES: Accompanying guardians (usually the mother) have a pivotal role in promoting recovery from childhood severe acute malnutrition on Nutritional Rehabilitation Units (NRUs). We describe the prevalence of maternal distress at an NRU in Malawi and identify factors associated with this. We tested the hypothesis that maternal distress during admission would be associated with reduced child weight gain over the 4-week post-discharge period. METHODS: Maternal distress was measured using the Self Reporting Questionnaire (SRQ) administered to mothers of consecutive children during NRU admission. Repeat SRQ was administered to mothers attending a follow-up clinic 4 weeks post discharge. Maternal, child and psychosocial variables were also measured. Child weight change from discharge to follow-up was compared between children of mothers scoring SRQ ≥ 8 and those scoring SRQ < 8. FINDINGS: A total of 244 mothers and their children were recruited. In total, 71% of mothers scored SRQ ≥ 8 during admission. In all, 155 of 222 mothers eligible to complete repeat SRQ did so, and 33.5% scored SRQ ≥ 8. Maternal distress at recruitment was associated with older child age, no confiding relationship with spouse, having had a previous child die, and the child having diarrhoea. Maternal distress at follow-up was associated with older child age, the child having diarrhoea or fever since discharge, and the child being HIV sero-positive. Maternal distress during admission was not associated with child weight gain at 4-week post-discharge follow-up. CONCLUSION: Levels of maternal distress are very high during child admission to an NRU. Persistent distress is associated with child health factors including HIV. Nutritional rehabilitation programmes should pay increased attention to carer psychological wellbeing using targeted evidence-based interventions.

Can a brief psychological intervention prevent anxiety or depressive disorders in cancer patients? A randomised controlled trial.

BACKGROUND: We tested whether a brief psychological intervention could prevent anxiety or depressive disorders among newly diagnosed cancer patients. PATIENTS AND METHODS: Patients free of anxiety or depressive disorder were randomised to receive immediate intervention (start of cancer treatment), delayed intervention (8 weeks after starting treatment) or usual care. They were stratified according to risk of developing anxiety or depressive disorders. Primary outcome was measured using a standardised psychiatric interview to detect any anxiety or depressive disorder at 6 and 12 months following the cancer diagnosis. Analyses used conditional odds logistic regression models adjusting for age, gender, concerns and past history to compare outcome of all intervention patients with usual care. RESULTS: A total of 465 patients were recruited. In all, 313 (79%) of the 397 well enough to be interviewed completed the study. At 12 months, there was no difference between the groups receiving the intervention and usual care [odds ratio (OR) = 0.69, 95% confidence interval (CI) 0.41-1.17, P = 0.17]. In high-risk patients, those who received the intervention were less likely to develop an anxiety or depressive disorder compared with those who received usual care (OR = 0.54, 95% CI 0.29-1.00, P = 0.050). In low-risk patients, there was no difference (OR = 1.50, 95% CI 0.51-4.43, P = 0.47). CONCLUSION: A brief intervention, delivered by nonspecialists, promoted adjustment among newly diagnosed cancer patients at high risk of developing anxiety or depressive disorders.

The role of psychological distress and personality variables in the disablement process in rheumatoid arthritis.

OBJECTIVE: To test whether psychological distress and personality variables mediate or moderate physical health-related quality of life (HRQOL) in rheumatoid arthritis (RA) patients. METHODS: In 168 RA patients the following self-report instruments were administered: the Health Assessment Questionnaire (HAQ), the General Health Questionnaire (GHQ), the Defence Style Questionnaire (DSQ), the Hostility and Direction of Hostility Questionnaire (HDHQ), and the Sense of Coherence (SOC) scale. A total of 152 patients with several rheumatological disorders [56 with systemic sclerosis (SSc), 56 with systemic lupus erythematosus (SLE) and 40 with Sjögren's syndrome (SS)] served as disease controls. The outcome measure was the physical scale of the World Health Organization Quality of Life Instrument, Short Form (WHOQOL-BREF). We used hierarchical regression to determine whether our data were consistent with the disablement process model. RESULTS: In RA patients, sense of coherence was associated with physical HRQOL but the relationship was mediated by psychological distress. Self-sacrificing defence style moderated the relationship between pain and physical HRQOL: pain was associated with impaired physical HRQOL only in patients with predominant self-sacrificing defence style. Although psychological distress and personality variables were also associated with physical HRQOL in the disease control group, the moderating effects of personality on physical HRQOL were unique to RA. Thus, in RA, psychological distress, functional disability, and the interaction term between pain and self-sacrificing defence style were independently associated with physical HRQOL. CONCLUSIONS: In RA patients, psychological distress mediated the association of personality variables with physical HRQOL but personality moderated the effects of pain on physical HRQOL and this could be relevant to psychological interventions.

Development of a Nanofabricated Sensor for Monitoring Intraocular Pressure via Ocular Tissue Strain.

As the number of individuals developing glaucoma is increasing, researchers and ophthalmologists are exploring new approaches to monitor intraocular pressure, which is a critical measurement for glaucoma detection. Current monitoring methods, such as implantable pressure sensors and wearable contact lenses with sensors, are being explored in eye research clinics. However, these systems currently lack in providing 24 hours data through a practical platform for large-scale use. This paper presents a novel method that provides constant measurements of the scleral strain, which is correlated with the change of intraocular pressure, using a nanofabricated discrete resistor array implant sensor. A preliminary bench-top test was performed using the sensor, and it showed that the nanofabricated 1.6 mm by 2.7 mm resistor array exhibits discrete sensing levels at increments of 41 ohms as a fixture needle traversed approximately half of the array. Though the nanosensor is in the prototype developing stage, it promises a new modality for constant, remote, and around the clock glaucoma monitoring.

Guidelines on the irritable bowel syndrome: mechanisms and practical management.

BACKGROUND: IBS affects 5-11% of the population of most countries. Prevalence peaks in the third and fourth decades, with a female predominance. AIM: To provide a guide for the assessment and management of adult patients with irritable bowel syndrome. METHODS: Members of the Clinical Services Committee of The British Society of Gastroenterology were allocated particular areas to produce review documents. Literature searching included systematic searches using electronic databases such as Pubmed, EMBASE, MEDLINE, Web of Science, and Cochrane databases and extensive personal reference databases. RESULTS: Patients can usefully be classified by predominant bowel habit. Few investigations are needed except when diarrhoea is a prominent feature. Alarm features may warrant further investigation. Adverse psychological features and somatisation are often present. Ascertaining the patients' concerns and explaining symptoms in simple terms improves outcome. IBS is a heterogeneous condition with a range of treatments, each of which benefits a small proportion of patients. Treatment of associated anxiety and depression often improves bowel and other symptoms. Randomised placebo controlled trials show benefit as follows: cognitive behavioural therapy and psychodynamic interpersonal therapy improve coping; hypnotherapy benefits global symptoms in otherwise refractory patients; antispasmodics and tricyclic antidepressants improve pain; ispaghula improves pain and bowel habit; 5-HT(3) antagonists improve global symptoms, diarrhoea, and pain but may rarely cause unexplained colitis; 5-HT(4) agonists improve global symptoms, constipation, and bloating; selective serotonin reuptake inhibitors improve global symptoms. CONCLUSIONS: Better ways of identifying which patients will respond to specific treatments are urgently needed.

The validation of personal health questionnaire amongst people of Pakistani family origin living in the United Kingdom.

BACKGROUND: The Personal Health Questionnaire (PHQ) was developed to screen for depressive disorder in an English speaking population. Its validity in Urdu speaking people of Pakistani family origin living in UK is yet to be established. METHODS: The PHQ was used to screen for depression in a two phase primary care based study of depressive disorder in people of Pakistani family origin residing in Manchester, UK. A proportion of high scorers (PHQ> or =7) and a random selection of low scorers (PHQ 0-6) were interviewed with the Psychiatric Assessment Schedule (PAS) to confirm caseness (ID> or =5). A receiver operator characteristic curve (ROC) analysis was carried out to confirm the optimum threshold value. RESULTS: The PHQ was used to screen 218 subjects with cut off of PHQ> or =7. 46 high scorers and 31 low scorers were interviewed in second stage using PAS. At this threshold PHQ has a sensitivity of 70.4% and specificity of 89.3%. CONCLUSIONS: Findings of this study confirm high sensitivity and specificity of PHQ amongst people of Pakistani family origin. It can be used as a screening instrument to detect depression in Urdu speaking population in UK.

Do care patterns change over time in a newly established mental health service? A report from the UK700 trial.

PURPOSE: Data on the process of mental health care is scant. Most studies focus on services at their inception when activity may be atypical and then usually present data only mean values for the reported variables over the whole study period. We aimed to test whether care delivery changes over time, and to describe any changes at the individual patient and team levels. METHODS: Process data on 272 patients in three new intensive case management (ICM) teams were collected over 2 years. Interventions were prospectively recorded using clinician-derived categories. Changes over time are described at both patient and team level. RESULTS: The number of contacts and the proportion of face-to-face activity were remarkably constant after the first month at the patient level. The proportion of 'psychiatric' interventions (main focus on medication or a specific 'mental health' intervention performed) increased greatly after the first 6 months. The care activity received by individual patients varied considerably. Overall, teams varied significantly in the extent to which their activity rates were sustained over time. CONCLUSIONS: New ICM teams deliver highly individualised care with more marked differences in treatment patterns between patients in the same team than mean differences between teams. The early 'engagement' period is marked by a greater focus on social care. There is evidence of differences in sustainability of the services by site.

Cost-effectiveness of brief psychodynamic-interpersonal therapy in high utilizers of psychiatric services.

BACKGROUND: It is known that a small number of patients with mental health problems have chronic disorders and account for a disproportionate amount of mental health costs. This randomized controlled trial evaluated the cost-effectiveness of psychodynamic-interpersonal therapy vs treatment as usual in patients with mental health problems who were unresponsive to usual treatment. METHOD: Subjects (N = 110) with nonpsychotic disorders unresponsive to 6 months of routine specialist mental health treatment were enrolled in a randomized controlled trial. Sixty-three percent were women, the mean age was 41.4 years, the median duration of illness was 5 years, 68% were unemployed or receiving state benefits because of illness, and 75.5% had a depressive illness. Intervention patients received 8 weekly sessions of psychodynamic-interpersonal psychotherapy. Control patients received usual care from their psychiatrist. Outcome measures included ratings of psychological distress and health status and a detailed economic evaluation. Analysis was conducted on an intent-to-treat basis. RESULTS: Subjects randomized to psychotherapy had a significantly greater improvement than controls in psychological distress and social functioning 6 months after the trial. Baseline treatment costs were similar for both groups. Subjects who received psychotherapy showed significant reductions in the cost of health care utilization in the 6 months after treatment compared with controls. The extra cost of psychotherapy was recouped within 6 months through reductions in health care use. CONCLUSION: These preliminary findings suggest that brief psychodynamic-interpersonal therapy may be cost-effective relative to usual care for patients with enduring nonpsychotic symptoms who are not helped by conventional psychiatric treatment.

Common and unique associated factors for medically unexplained chronic widespread pain and chronic fatigue.

OBJECTIVE: Chronic widespread pain and chronic fatigue share common associated factors but these associations may be explained by the presence of concurrent depression and anxiety. METHODS: We mailed questionnaires to a randomly selected sample of people in the UK to identify participants with chronic widespread pain (ACR 1990 definition) and those with chronic fatigue. The questionnaire assessed sociodemographic factors, health status, healthcare use, childhood factors, adult attachment, and psychological stress including anxiety and depression. To identify persons with unexplained chronic widespread pain or unexplained chronic fatigue; we examined participant's medical records to exclude medical illness that might cause these symptoms. RESULTS: Of 1443 participants (58.0% response rate) medical records of 990 were examined. 9.4% (N=93) had unexplained chronic widespread pain and 12.6% (N=125) had unexplained chronic fatigue. Marital status, childhood psychological abuse, recent threatening experiences and other somatic symptoms were commonly associated with both widespread pain and fatigue. No common effect was found for few years of education and current medical illnesses (more strongly associated with chronic widespread pain) or recent illness in a close relative, neuroticism, depression and anxiety scores (more strongly associated with chronic fatigue). Putative associated factors with a common effect were associated with unexplained chronic widespread pain or unexplained chronic fatigue only when there was concurrent anxiety and/or depression. DISCUSSION: This study suggests that the associated factors for chronic widespread pain and chronic fatigue need to be studied in conjunction with concurrent depression/anxiety. Clinicians should be aware of the importance of concurrent anxiety or depression.

The relationship between psychosocial parameters and outcome in irritable bowel syndrome.

This article reviews the evidence that psychiatric disorders have an adverse influence on the outcome of irritable bowel syndrome (IBS) and relates this to the close relationship between psychological symptoms and severity of abdominal pain, bloating, and diarrhea. Therefore, accurate measurement of psychological symptoms may be an important aspect of trial design for IBS therapy. The importance of psychological distress and health anxiety in differentiating "consulters" and "nonconsulters" for IBS is reviewed. The consequences of excluding from a trial people with certain types of psychiatric disorder or with a known past history of sexual abuse are considered.

Systematic reviews of the effectiveness of day care for people with severe mental disorders: (1) acute day hospital versus admission; (2) vocational rehabilitation; (3) day hospital versus outpatient care.

UNLABELLED: ***ACUTE DAY HOSPITAL VERSUS ADMISSION FOR ACUTE PSYCHIATRIC DISORDERS*** BACKGROUND: Inpatient treatment is an expensive way of caring for people with acute psychiatric disorders. It has been proposed that many of those currently treated as inpatients could be cared for in acute psychiatric day hospitals. OBJECTIVE: The aim of this review was to assess the effectiveness and feasibility of day hospital versus inpatient care for people with acute psychiatric disorders. METHODS - STUDY SELECTION: Eligible studies were randomised controlled trials of day hospital versus inpatient care for people with acute psychiatric disorders. Studies were excluded if they were primarily concerned with elderly people, children, or patients with a diagnosis of organic brain disease or substance abuse. METHODS - DATA SOURCES: We searched the Cochrane Controlled Trials Register, MEDLINE, EMBASE, CINAHL, PsycLIT, and the reference lists of articles. Researchers were approached to identify unpublished studies. Trialists were asked to provide individual patient data. METHODS - DATA EXTRACTION: Data were extracted independently by two reviewers and cross-checked. METHODS - DATA SYNTHESIS: Relative risk (RR) and 95% confidence intervals (CIs) were calculated for dichotomous data. Weighted or standardised means were calculated for continuous data. Day hospital trials tend to present similar outcomes in slightly different formats, making it difficult to synthesise the data. Individual patient data were therefore sought so that outcomes could be re-analysed using a common format. RESULTS: Nine trials met the inclusion criteria (involving 1568 randomised patients and 2268 assessed for suitability of day hospital treatment). Individual patient data were obtained for four trials (involving 594 people). A sensitivity analysis of combined data suggested that day hospital treatment was feasible for at worst 23.2% (n = 2268; 95% CI, 21.2 to 25.2) and at best 37.5% (n = 1768; 95% CI, 35.2 to 39.8) of those currently admitted to inpatient care. Individual patient data from three trials showed no difference in the number of days in hospital (combining day hospital days and inpatient days) between day hospital patients and controls (n = 465; weighted mean difference (WMD) = -0.38 days/ month; 95% CI, -1.32 to 0.55). However, compared with controls, patients randomised to day hospital care spent significantly more days in day hospital care (n = 265; WMD = 2.34 days/month; 95% CI, 1.97 to 2.70) and significantly fewer days in inpatient care (n = 265; WMD = -2.75 days/month; 95% CI, -3.63 to -1.87). There was no difference between readmission rates for day hospital and control patients (n = 667; RR = 0.91; 95% CI, 0.72 to 1.15). Individual patient data from three trials showed a significant time-treatment interaction, indicating a more rapid improvement in mental state (n = 407; c2 = 9.66; p = 0.002), but not social functioning (n = 295; c2 = 0.006; p = 0.941) amongst day hospital patients. Four of five trials demonstrated that day hospital care was cheaper than inpatient care (with overall cost reductions ranging from 20.9% to 36.9%). CONCLUSIONS: Acute day hospitals are an attractive option in situations where demand for inpatient care is high and facilities exist that are suitable for conversion. They are a less attractive option when demand for inpatient care is low and where effective alternatives already exist. The interpretation of day hospital research would be enhanced if future trials made use of the common set of outcome measures used in this review. It is important to examine how acute day hospital care can be most effectively integrated into a modern community-based psychiatric service. ***VOCATIONAL REHABILITATION FOR PEOPLE WITH SEVERE MENTAL DISORDERS*** BACKGROUND: People who are disabled by severe mental disorders experience high rates of unemployment, but most want to work. Prevocational training (PVT) is the traditional approach to helping such people to return to work. PVT assumes that a period of preparation is required before those with a severe mental disorder can enter into competitive employment. Supported Employment (SEm) is a new approach that places clients in competitive employment without extended preparation. Both PVT and SEm are widely practised, but it is unclear which is the most effective. OBJECTIVES: The overall objective of this review was to assess the effectiveness of PVT and SEm relative to each other and to standard care (in hospital or the community) for people with severe mental disorders. In addition, the review examined the effectiveness of: (1) special types of PVT ("clubhouse" model) and SEm (individual placement and support model); and (2) modifications for enhancing PVT (e.g. payment or psychological interventions). METHODS - STUDY SELECTION: Eligible studies were randomised controlled trials (RCTs) examining the effectiveness of vocational rehabilitation approaches (PVT and SEm or modifications) for people of working age and suffering from a severe mental disorder. METHODS - DATA SOURCES: Relevant trials were identified from searches of the Cochrane Schizophrenia Group's specialised register, MEDLINE, EMBASE, CINAHL and PsycLIT, and the reference lists of all identified studies and review articles. Researchers who were active in the field were approached in order to identify unpublished studies. METHODS - DATA EXTRACTION: All data were extracted independently by two reviewers and cross-checked. Continuous data were excluded if they were collected by using an unpublished scale or were based on a subset of items from a scale. METHODS - DATA SYNTHESIS: For all comparisons, the primary outcome was the number of clients who were in competitive employment at various time points. Secondary outcomes were: other employment outcomes, clinical outcome and costs. The relative risk (RR) and number-needed-to-treat (NNT) were calculated for the relevant categorical outcomes. Continuous data were either presented as in the original trial reports or, where possible, combined across trials as a standardised mean difference score. RESULTS: Eighteen RCTs of reasonable quality were identified: PVT versus hospital controls, three RCTs, n = 172; PVT versus community controls, five RCTs, n = 1204; modified PVT, four RCTs, n = 423; SEm versus community controls, one RCT, n = 256; and SEm versus PVT, five RCTs, n = 491). The main finding was that, on the primary outcome (number in competitive employment), SEm was significantly more effective than PVT at all time points (e.g. at 12 months, SEm 34% employed, PVT 12% employed; RR of not being in competitive employment = 0.76, 95% confidence interval 0.69 to 0.84, NNT = 4.5). Clients in SEm also earned more and worked more hours per month than those in PVT. CONCLUSIONS: The main finding was that SEm was more effective than PVT for patients suffering from a severe mental disorder who wanted to work. There was no evidence that PVT was more effective than standard community care or hospital care. The implication of these findings is that people suffering from mental disorders who want to work should be offered the option of SEm. Commissioning agencies would be justified in encouraging vocational rehabilitation (VR) providers to develop more SEm schemes. From a research perspective, the cost-effectiveness of SEm should be examined in larger multicentre trials, both within and outside the USA. There is a case for countries outside the USA to survey their existing VR services to determine the extent to which the most effective interventions are being offered. ***DAY HOSPITAL VERSUS OUTPATIENT CARE FOR PATIENTS WITH PSYCHIATRIC DISORDERS*** BACKGROUND: This review considers the use of day hospitals as an alternative to outpatient care. Two typesof day hospital provision are covered: "day treatment programmes" and "day care centres". Day treatment programmes are day hospitals that are used to enhance the treatment of patients with anxiety or depressive disorders who have failed to respond to outpatient care. Day care centres are day hospitals that offer structured support to patients with long-term severe mental disorders who would otherwise be treated in an outpatient clinic. OBJECTIVES: There were two objectives: first, to assess the effectiveness of day treatment programmes versus outpatient care for people with non-psychotic disorders; and, secondly, to assess the effectiveness of day care centres versus outpatient care for people with severe long-term disorders. METHODS - STUDY SELECTION: Eligible studies were randomised controlled trials comparing day hospital care (either a day treatment programme or a day care centre) with outpatient care. Studies were ineligible if they were largely restricted to patients who were aged under 18 or over 65 years or who had a primary diagnosis of substance abuse or organic brain disorder. METHODS - DATA SOURCES: Relevant trials were identified from searches of the Cochrane Controlled Trials Register, MEDLINE, EMBASE, CINAHL, PsycLIT, and the reference lists of all identified studies and review articles. Researchers were approached to identify unpublished studies. Trialists were asked to provide individual patient data. METHODS - DATA EXTRACTION: All data were extracted independently by two reviewers and cross-checked. METHODS - DATA SYNTHESIS: Relative risks and 95% confidence intervals were calculated for dichotomous data. Standardised mean differences were calculated for continuous data. RESULTS: There was evidence from two of the five trials identified suggesting that day treatment programmes were superior to continuing outpatient care in terms of improving psychiatric symptoms. There was no evidence to suggest that day treatment programmes were better or worse than outpatient care on any other clinical or social outcome variable or on costs. (ABSTRACT TRUNCATED)

Negative symptoms of schizophrenia and compliance with medication.

Poor compliance with medication has been reported in up to 40 percent of outpatients with schizophrenia. This study examines the relationship between compliance with depot neuroleptic medication and severity of negative symptoms of schizophrenia. Compliance with depot neuroleptic medication during the preceding year was calculated for 64 patients with a DSM-III-R diagnosis of schizophrenia. The severity of negative symptoms was assessed using the Scale for the Assessment of Negative Symptoms (SANS). Patients who complied poorly with medication had significantly greater severity of negative symptoms of schizophrenia, especially avolition, apathy, and alogia. Duration of illness and duration of prescribed medication were independently associated with compliance, but no other features were associated in the multiple regression model. These findings suggest that negative symptoms are one of the factors of importance in determining whether a patient will attend for depot neuroleptic medication.

The relationship of current psychiatric disorder to functional disability and distress in patients with inflammatory bowel disease.

Although prior theories about psychiatric disorders causing inflammatory bowel disease (IBD) have largely been discredited, these same disorders have at times been associated with functional gastrointestinal symptoms such as those found in irritable bowel syndrome. Since functional gastrointestinal symptoms can also occur in patients with organic pathology, we hypothesized that a current psychiatric disorder might amplify or produce additional gastrointestinal symptoms in patients with organic gastrointestinal diseases such as IBD, leading to additive functional disability and decreased quality of life. This pilot study evaluated a sequential sample of 40 IBD patients using the NIMH Diagnostic Interview Schedule, structured interviews for functional gastrointestinal symptoms, and prior episodes of emotional, physical, and sexual abuse as well as self-report measures of personality and disability. We compared IBD patients with and without a current psychiatric disorder while controlling for disease severity. Eight patients with major depression were treated with antidepressants. Patients with a current psychiatric disorder had significantly higher 1) mean number of lifetime psychiatric diagnoses, 2) prevalence rates of prior sexual and physical victimization, and, 3) mean numbers of both gastrointestinal and other medically unexplained symptoms despite no differences in severity of IBD. Significant and trend level differences were apparent on several measures of functional disability. A regression analysis showed that number of psychiatric diagnoses, number of functional gastrointestinal symptoms, and dissociation scale scores significantly discriminated the groups. Treatment of current major depression decreased functional disability despite no objective changes in gastrointestinal disease severity. It was concluded that the presence of a current psychiatric disorder appears to alter the perception of disease severity in patients with IBD. Nonrecognition of the psychiatric disorder may lead to unnecessary and aggressive interventions for IBD patients such as medication changes, invasive testing, or surgery. The presence of a current psychiatric illness also appears to be associated with increased functional disability. Psychiatric evaluation and treatment, therefore, have an important role in the ongoing management of IBD patients with distressing gastrointestinal symptoms not directly attributable to their IBD.

Consultation-Liaison psychiatric service delivery: results from a European study.

The reported findings of the European Consultation-Liaison Workgroup (ECLW) Collaborative Study describe consultation-liaison service delivery by 56 services from 11 European countries aggregated on a C-L service level. During the period of 1 year (1991), the participants applied a standardized, reliability tested method of patient data collection, and data were collected describing pertinent characteristics of the hospital, the C-L service, and the participating consultants. The consultation rate of 1% (median; 1.4% mean) underscores the discrepancy between epidemiology and the services delivered. The core function of C-L services in general hospitals is a quick, comprehensive emergency psychiatric function. Reasons to see patients were the following. deliberate self-harm (17%), substance abuse (7.2%), current psychiatric symptoms (38.6%), and unexplained physical complaints (18.6%) (all means). A significant number of patients are old and seriously ill. Mood disorders and organic mental disorders are most predominant (17.7%). Somatoform and dissociative disorders together constitute 7.5%. C-L services in European countries are mainly emergency psychiatric services and perform an important bridge function between primary, general health, and mental health care.

Life events and physical illness.

This paper reviews research on the role of stressful life events in the aetiology of physical illness. Particular attention is given to the methodological problems involved in the identification and measurement of life events. There has been insufficient sound research for firm conclusions to be drawn but prospective studies make it clear that assessment of life events will lead to a more complete understanding of how psychosocial factors interact with bodily functioning. Future research studies will need to be based on an interactional model.

The cost of somatization.

Fifty-two consecutive patients referred to a psychiatrist with somatic symptoms of underlying psychiatric disorder were studied. The costs of investigations performed in the general hospital prior to referral to the psychiatrist were assessed. The median cost was pounds 286 but the range was pounds 25-2300. Those costs were determined by the physician's original assessment of the likelihood of organic disease and were independent of the view expressed in the general practitioner's referral letter. This preliminary study indicates the need to understand more fully the determinants of early or late referral of somatization patients to a psychiatrist. The determinants include the diagnostic difficulties of the presenting symptom, patient factors including resistance to adopting a psychological view of the symptoms, and physician factors determining the number of investigations performed to exclude organic disease.

Life events and somatisation among students.

137 first year undergraduates presenting to the student health service were studied to assess the effect of life events, locus of control, psychiatric symptoms and illness behaviour in determining whether a psychological or physical symptom was presented to the doctor. Psychological presenters were small in number, but showed significantly more life events additional to those expected during the first year of higher education. They also showed greater external attribution for affiliation and more prominent illness behaviour. 65% of the sample showed GHQ scores indicating probable psychiatric illness. Those with a high GHQ score and physical presentation, who did not have an organic basis for their symptoms were termed 'somatisers'. Like those with a psychological presentation, the somatisers had experienced a break, or serious difficulty in a close relationship with a member of the opposite sex, or the death of a close relative or friend. This study has used a new method of assessment of life events among students and the results indicate the high prevalence of somatisation among first year college students attending the health centre.

Depression, cognitive impairment and social stress in multiple sclerosis.

Twenty-four out-patients with established multiple sclerosis (MS) who had been neurologically assessed underwent detailed psychiatric, cognitive and social assessments. Depression was associated with significant cognitive impairment and with social stress but not with degree of neurological impairment, specific neurological symptoms, disability or handicap. It is suggested that depression in relapsing-remitting MS may arise when cognitive deficits cause problems in occupational performance and impinge on close personal relationships.
