The detection of psychological problems by General Practitioners--influence of ethnicity and other demographic variables.

BACKGROUND: Common mental illness in Black Africans and Black Caribbeans has been relatively little studied in the UK. Previous studies of the detection of psychological problems by General Practitioners (GPs) in these groups have been inconclusive. AIMS: The aim of this study was to investigate the prevalence, detection and management of psychological problems in General Practice among Black Caribbeans and Black Africans compared to White English attenders and to examine the relative contribution of other sociodemographic factors to these main outcome variables. METHOD: Consecutive attenders aged 16-65 years at 18 General Practitioners in South-East London completed the General Health Questionnaire (GHQ-12) before seeing the GP. The GPs rated the current emotional state of the patients at the end of each consultation. Comparison of the GHQ and GP ratings was used to compute the detection indices. RESULTS: A total of 1211 patients aged 16-65 years were approached to take part in the study. Of the patients, 75 (6%) declined or were not able to complete the GHQ. In all, 994 individuals had both GP and GHQ ratings. There was an overall probable prevalence of 37%, of which 73% were identified as cases by the GPs. Black African patients had lower rates of common mental disorders, were less likely to be detected as psychiatric cases by the GP and less likely to receive active management for their psychological problems than Black Caribbean and White English patients. Rates of prevalence, detection and management were similar between Black Caribbean and White English patients. In the multivariate analysis, ethnicity, employment and age all played a significant independent role in predicting probable prevalence. The patients' reported decision to talk to their GP about psychological problems was the main predictor of detection. Ethnicity did not independently predict detection, but Black African cases were less likely to say that they would talk to their GP about psychological problems. GPs' identification indices mirrored probable prevalence, suggesting that GPs were more sensitive to detecting psychiatric illness in individuals belonging to groups which commonly presented as symptomatic. CONCLUSIONS: The findings suggest that in General Practice the prevalence of common mental disorders, their detection and management in Black Caribbeans are similar to those in White English, but that Black Africans have lower prevalence, are less likely to be detected and are less likely to receive active management. The study of GP consulters presents problems for the interpretation of these results and it may be that Black Africans with psychological problems are less likely than their Caribbean and English counterparts to attend their GP, and less willing to speak to them about these problems when they do. Future similar studies should distinguish Black African and Black Caribbean subjects in their analyses, as categories such as 'Afro-Caribbean' may mask important differences in attitudes and illness behaviour.

Modelling suicide risk in affective disorders.

BACKGROUND: The lifetime risk of suicide in affective disorders is commonly quoted as 15%. This stems from hospital populations of affective disorders. AIMS: To model the lifetime prevalence of suicide using data on completed suicides from one English Health District and community-based rates of prevalence of affective disorders. METHODS: A secondary analysis of a primary data set based on 212 suicides in North Staffordshire was undertaken. The population rates of psychiatric morbidity were obtained from the National Comorbidity Survey. RESULTS: The model suggests a lifetime prevalence rate of suicide for any affective disorder at 2.4%, with a rate for those uncomplicated by substance abuse, personality disorder or non-affective psychosis at 2.4%, and a rate for uncomplicated cases who had no mental health service contact at 1.1%. CONCLUSIONS: Lifetime prevalence rates of suicide in subgroups of affective disorders may be lower than the traditional rates cited for hospital depression. This has implications for primary care projects designed to investigate the occurrence of and the prevention of suicide.

Prediction of readmission to acute psychiatric units.

BACKGROUND: Many factors are known to influence readmission to psychiatric wards, and readmission rates have been suggested as proxy outcome indicators of quality. METHOD: Korner returns were used to ascertain readmission rates for all psychiatric admissions to acute wards in North Staffordshire, 1987-1993. Predictor variables were derived from Korner returns or obtained from the 1991 Census data. Survival analysis techniques were used to examine which variables predicted readmission. RESULTS: A predictive model was derived using Cox regression, which followed the observed data at greater than chance probability (chi2=48.5, df=4, P < 0.001). A psychotic diagnosis was the most influential predictor of readmission. CONCLUSION: Length of stay is not predictive in the Cox regression model, which suggests patients are not being prematurely discharged. The derived models may have value in service planning, audit and resource allocation.

A prospective study of primary care patients with musculoskeletal pain: the identification of predictive factors for chronicity.

Primary care faces the challenge of reducing the proportion of patients continuing with musculoskeletal pain beyond the acute phase. This study assessed patients presenting in general practice with a four- to 12-week history of pain and re-assessed them 12 weeks later. Patients whose pain was described as 'none' or 'slight' were allocated to the 'acute group', and those whose pain continued to be 'moderate' or 'severe' were allocated to the 'chronic group'. Comparative analysis of the two groups' responses at initial assessment identified pain intensity, active coping score, and previous pain episode to be factors independently predictive of chronicity.

The North Staffordshire Suicide Study: a case-control study of suicide in one health district.

BACKGROUND: The aim of the study was to identify sociodemographic and clinical risk factors for death from suicide and undetermined injury in residents of one health district. METHOD: Data were collected on all cases of suicide (ICD-9 E950-959) and undetermined injury (ICD-9 E980-989) for residents in North Staffordshire Health District between 1991 and 1995. Controls identified from the Coroner's inquest register, who died from other causes, were matched for age and sex. RESULTS: Two hundred and twelve pairs of cases and matched controls were identified. Multivariate analysis (conditional logistic regression) showed that the risk of death due to suicide and undetermined death was associated with: recent separation, relationship difficulties, experience of financial difficulties, history of past criminal charges or contact with the police, a past history of deliberate self-harm, being on psychotropic medication at the time of death and a diagnosis of bipolar affective disorder. For sociodemographic variables, a univariate analysis found associations between the cases and being separated, living alone, having a past history of criminal charges and unemployment. Cases were more likely to have a psychiatric disorder, past history of deliberate self-harm and a past history of psychiatric contact for themselves or a family member. Controls were more likely to have a current medical disorder. Cases were more likely than controls to be on any form of medication at the time of death and to have received a prescription for psychotropic or non-psychotropic medication in the week and month before death. Cases were more likely than controls to have had contact with medical services in the week and month before death, with the general practitioner in the week before death and with psychiatric services at any time in the year before death. Strong associations were found between suicide and undetermined injury and life events such as recent separation and bereavement, and financial and relationship difficulties. CONCLUSIONS: The study provides an analytical investigation utilizing a dead control group, data gathered from several sources and adequate numbers of cases. It confirms many of the risk factors identified in other studies and highlights the high proportion of suicides who have been in recent contact with the criminal justice system or have been prescribed medication shortly before death.

North Staffordshire Community Beds Study: longitudinal evaluation of psychiatric in-patient units attached to community mental health centres. I: Methods, outcome and patient satisfaction.

BACKGROUND: This study evaluates two in-patient units attached to community mental health centres (CMHCs) that were designed to supplement acute in-patient care and to integrate with community-based after-care services. AIM: To examine the comparative outcome of patients with severe mental illness (SMI) admitted to the two units. METHOD: All patients with SMI admitted to the acute psychiatric wards serving the two CMHCs, those transferred to the community in-patient units and those admitted directly to these units (n = 110) were compared with patients (n = 67) admitted to acute wards serving two similar catchment areas without associated community beds. Baseline clinical and social measures were made and repeated at six and 12 months. Satisfaction with services was assessed at 12 months. RESULTS: The experimental group showed significantly better outcomes, significant reduction in unmet need and better satisfaction with services. CONCLUSIONS: The use of the community beds appears to have significant benefits for patients with SMI.

North Staffordshire Community Beds Study: longitudinal evaluation of psychiatric in-patient units attached to community mental health centres. 2: Impact upon costs and resource use.

BACKGROUND: Innovative approaches to the provision of psychiatric care must justify their ability to improve the quality of life within the resource constraints imposed on psychiatry. AIMS: To examine the average costs per patient of the experimental and control group services. METHOD: An individual patient costing methodology that identified, measured and valued all public and private resources. RESULTS: The experimental group was more likely to remain in contact with services over a 12-month period, had fewer acute readmissions and spent less time in acute in-patient units. There were significantly different levels and patterns of resource consumption between the groups and between the two separate catchment areas. CONCLUSION: The cost analysis should be assessed in the context of the previous outcome analysis. It is likely, but not inevitable, that such units will increase the overall costs of care provision; this largely depends on the effectiveness with which such units are integrated into existing care provision.

Randomisation in clinical trials.

BACKGROUND: Several studies of papers published in non-psychiatric medical journals that report on randomised controlled trials (RCTs) indicate that there is inadequate reporting of the process by which randomisation is carried out. AIMS: To examine the adequacy of the reporting of the procedure of randomisation in clinical trials of parallel design published in the British Journal of Psychiatry (BJP) and the American Journal of Psychiatry (AJP). METHODS: All issues of the BJP and the AJP published between January 1990 and December 1998 were surveyed, and papers that reported on RCTs were examined to judge the adequacy of the reporting of the process of randomisation. RESULTS: We found 183 papers which claimed to report on RCTs (73 in the BJP and 110 in the AJP). Nine (8.2%) of those in the AJP and six (8.2%) in the BJP described the technique of creating the randomisation sequence. Two (1.8%) of those in the AJP and 11 (15.1%) of those in the BJP described the mechanism of allocating treatment. One paper in the AJP and five papers in the BJP described both the generation of random numbers and allocation. CONCLUSIONS: Adequate reporting of the method of randomisation was uncommon. The RCT status of some of the papers must therefore be in doubt.

Social indicators and the prediction of psychiatric admission in different diagnostic groups.

BACKGROUND: Recent findings indicate that the established association between social indicators of deprivation and psychiatric admission rates may not hold across all diagnoses. METHOD: Admission rates in individuals aged 16-64 years for 71 electoral wards in North Staffordshire were calculated for six diagnostic groups using data from the Korner Episode System for 1987-1993. These were correlated with selected individual census variables, Townsend and Jarman indices. The ability of regression models to predict admission rates was tested. RESULTS: The strongest correlations were found for total admissions (r 0.44-0.79). Strong correlations were found for neurotic disorders/depression (r 0.29-0.62), schizophrenia (r 0.24-0.59), all non-psychotic disorders combined (r 0.41-0.71) and all psychotic disorders combined (r 0.33-0.67). Predicted admission rates for total admissions, psychotic and non-psychotic admissions using regression models showed strong positive correlations with observed admission rates. CONCLUSIONS: The strong correlations between social indicators of deprivation and total psychotic admission rates are consistent with the results of previous studies. The strong associations between social indicators and admissions for non-psychotic disorders is contrary to previous findings and may be partly explained by the relatively high admission rates for neurotic disorders.

The South London Somatisation Study. II. Influence of stressful life events, and secondary gain.

BACKGROUND: A study of the influence of life-event stress on the onset and course of acute somatisation in primary care. METHOD: Forty-four somatisers were compared with 11 subjects who had psychiatric disorder but complained only of psychological symptoms, 39 patients who had 'mixed' conditions involving independent physical and psychiatric illness, 90 patients who had physical illness, and 123 healthy members of the general population. RESULTS: Severely threatening life events were more common among all subjects with psychiatric disorder. A novel contextual rating of the potential of stressors to produce symptoms for 'secondary gain' was developed. In the 38 weeks before symptom onset, somatisers and psychologisers were more likely to have experienced at least one event which had this potential. Somatisers were also less likely to adopt neutralising coping efforts when faced with such a crisis. CONCLUSIONS: The likelihood of adopting neutralising efforts was closely related to the presence of a joint index of parental problems in care and exposure to physical illness in the subject's childhood. In a two-year follow-up, subsequent functional illnesses were also associated with experiences which had secondary-gain potential, and subjects with childhood risk factors continued to have higher rates of crises with secondary-gain potential and to fail to adopt neutralising coping strategies.

The South London Somatisation Study. I: Longitudinal course and the influence of early life experiences.

In a two-year longitudinal study, a two-stage screening procedure was used to identify subjects in primary care with emotional disorder presenting with a recent onset of physical symptoms and a comparison sample of patients presenting with physical symptoms only. Somatisers (n = 44) were defined as subjects who had an emotional disorder but who presented with physical symptoms that could not be attributed to organic disease. The course and outcome of these conditions were compared with those of pure emotional disorder (n = 11), pure physical disorder (n = 90) and 'mixed' conditions (n = 39). The physical symptoms of somatisers were less likely to improve and lagged behind those of the other groups, and 16 of these acute somatisers went on to develop chronic somatoform disorders. Among somatisers, changes in physical symptom levels throughout the follow-up closely mirrored changes in emotional arousal. Emotionally disordered subjects reported more instances of parental lack of care, but somatisers were also more likely than other groups to report parental physical illness and to have had more physical illness themselves in childhood. A logistic regression suggests that adult somatisation is best modelled by parental lack of care followed by childhood illness.

The detection of psychiatric cases by Greek physicians: report on a study carried out in a Greek primary care setting.

The detection of psychiatric disorder by primary care physicians in Greece was investigated using four non-psychiatric physicians. The General Health Questionnaire indicated a high probable prevalence of psychiatric disorder (77.8%), but the physicians rated only 9.3% of the sample as cases. Eighty eight per cent of the probable cases were undetected by the doctors. The doctors' reporting of cases was not affected by the demographic characteristics of the sample and only weakly affected by the patients' total GHQ score. The high probable prevalence and low detection rate is a cause for concern and requires further investigation.

The development of community mental health centres in the U.K.

This paper describes a survey of British Community Mental Health Centres (CMHCs). CMHCs are by far the most visible manifestation of the implementation of community mental health care policies of the 1980s. While these centres have demonstrated achievements in terms of accessibility, co-ordination and responsiveness to clients, they have also been bedevilled by ambiguity. The vast majority of CMHCs aim to serve the needs of all forms of mental illness within their catchment area, yet in practice, they have frequently failed to meet the needs of people with long term severe disorders and concentrate instead on providing assessment and counseling services for neurotic and transient situational disorders. It appears that this is a function of an early failure of multidisciplinary teams to delineate boundaries and priorities. If the British CMHC movement sharpens its focus and combines this with a determination to address the complexities involved in both rationing and enhancing choice, it could begin to improve upon rather than simply repeat the history of similar developments in America.

The Mental Health Advice Centre in Lewisham.

This paper describes the use of a psychiatric service within a catchment area and the effects on existing services of establishing a community-based service, the Mental Health Advice Centre (MHAC). Major effects were the expansion of ambulatory services and an increased access to patients from primary care. Some of these findings are discussed. The importance of monitoring and evaluating novel community services is emphasised.

General practitioner referrals to an ambulatory psychiatric service. The effects of establishing an ease of access service.

The effects of establishing an ease of access 'walk-in' service on General Practitioner referrals to the ambulatory services of a catchment area psychiatric service are outlined. The characteristics of the patients referred are described. GPs made immediate and sustained use of the walk-in service and its creation expanded use of the ambulatory services by an overall 50%. Individual GPs were found to use the ambulatory services disproportionately and to discriminate between their use of the walk-in service and the coexisting traditionally run outpatient clinic. The walk-in service also allowed patients to refer themselves; a policy which did not result in a flood of inappropriate referrals but enabled patients, already familiar with the service, to re-establish contact in times of distress. The findings are discussed in terms of the current growth of Community Mental Health Centres in the United Kingdom and their implications for GP/Psychiatric Service liaison.
