We report on the inter-rater reliability of the Life Chart Schedule (LCS). The LCS is designed to assess the long-term course of schizophrenia in four key domains (symptoms, treatment, residence, and work) over two time periods (past two years, entire period of illness). The subjects were 27 consecutive admissions to a schizophrenia research unit. The LCS was filled out by pairs of raters, blinded to each others' ratings, using the same data (interview with subject and chart). Reliability was examined for 45 LCS ratings selected from all four domains and both time periods. Selected ratings pertained to the duration of specified experiences, the quality of these experiences, and the long-term time trend. The kappa statistic and the intra-class correlation coefficient (ICC) were used to determine inter-rater reliability for continuous and categorical ratings, respectively. LCS ratings proved reliable in all four key domains and both time periods. The reliability was fair to excellent for ratings of duration of experience (ICC ranged from 0.53 to 0.99), quality of experience (kappa ranged from 0.46 to 0. 92) and long-term time trends (kappa ranged from 0.66 to 0.94). The LCS can be used to obtain reliable ratings of the long-term course of schizophrenia in multiple domains. 相似文献

BACKGROUND: The short-term course of schizophrenia is reported to be better in some developing country settings. The long-term course in such settings, however, has rarely been studied. AIMS: To examine the long-term course and mortality of schizophrenia in patients with a poor 2-year course. METHOD: The report is based on two incidence cohorts of first-contact patients in urban and rural Chandigarh, India, originally recruited for the World Health Organization Determinants of Outcome of Severe Mental Disorders study. Patients were assessed using standardised instruments at 2- and 15-year follow-ups. RESULTS: Ninety-two per cent of the patients with a poor 2-year course had a poor long-term course and 47% died - a nine times higher mortality rate than among patients with other 2-year course types. CONCLUSIONS: In this developing country setting, a poor 2-year course was strongly predictive of poor prognosis and high mortality, raising questions about the adequacy of care for such patients. 相似文献

Prevalence of HIV infection among psychiatric patients in a New York City men's shelter. 总被引:13,自引:9,他引:4
We report on the prevalence of human immunodeficiency virus (HIV) infection among psychiatric patients in a New York City shelter for homeless men. We reviewed the records of all 90 men discharged from the shelter psychiatry program to community housing over a 2-year period. HIV serostatus was recorded for 62 of the 90 men. Of these 62, 12 (19.4%) were positive. There were 28 men whose serostatus was not recorded. Data on the HIV risk behaviors of these 28 men suggested that seroprevalence could have been similarly high among them. The results indicate an urgent need to develop and apply preventive interventions for HIV in this population. 相似文献

A case is described of mediastinal and hilar fibrosis in a woman aged 22 years. The fibrotic mass compressed the lobar arteries as well as the veins of various lobes of both lungs. These large vessels as well as numerous smaller arteries and veins were to a large extent obstructed by organized thrombi. It seems likely that 3 years after the beginning of symptoms the fibrosing process was still active. The case provides some support for an immunopathological aetiology of this condition. 相似文献

OBJECTIVE: The purpose of the study was to examine the inpatient and outpatient service use and 4-year outcomes of newly admitted psychotic patients during a period of rapid change in the provision of psychiatric services in a well-defined catchment area in New York State in the 1990s. METHOD: Subjects were 573 participants of the Suffolk County Mental Health Project. This group comprised patients with psychotic disorders first admitted between September 1989 and August 1995 to 12 inpatient facilities across Suffolk County, N.Y., and followed for up to 48 months. The subjects' service use, course of illness, symptomatic outcomes, suicide risk, homelessness risk, and satisfaction with care were compared across admission years. RESULTS: The length of inpatient stays decreased significantly across the years. However, the number of outpatient visits and therapy sessions did not vary. Although the patients admitted in later years were more symptomatic at admission to their first hospitalization, their course and outcomes over the follow-up period were not worse and they were not less satisfied with their care, compared with the patients admitted in earlier years. CONCLUSIONS: The clinical characteristics of patients and the role of inpatient care in the management of patients with psychotic disorders gradually changed during the 1990s. These changes, however, were not associated with changes in the use of outpatient services or outcomes. Nevertheless, shorter hospital stays and the presence of more severely ill patients highlight the need for more attention to linkage to aftercare and enhancement of support networks in the community. 相似文献
