The reliability of psychiatric diagnosis in Israel's Psychiatric Case Register.

To determine the reliability of psychiatric diagnoses in the Israel Psychiatric Case Register, DSM-III criteria were applied to case record abstracts of first admissions to a large psychiatric hospital in Jerusalem. The DSM-III diagnoses were compared with ICD-8 records diagnoses. Between 40 and 50% of those originally diagnosed as schizophrenia were re-diagnosed into less severe categories. The proportion diagnosed as affective disorder doubled from 21% for ICD-8 diagnoses to 40% for DSM-III diagnoses. The unreliability concerned the diagnoses of schizophrenia and affective disorder. Findings suggest that the introduction of standardized diagnostic criteria in Israel will lead to a substantial increase in the number of cases diagnosed as affective disorder, although difficulties involved in differentiating schizophrenia from the major affective disorders remain. The DSM-III findings suggest a high prevalence of affective disorders among Jews.

DPS--a computerised diagnostic problem solver.

The paper contains a short description of the DPS system which is a computerized diagnostic problem solver. The system is under development of the Research Institute of Medical Bionics in Bratislava, Czechoslovakia. Its underlying philosophy yields from viewing the diagnostic process as process of cognitive problem solving. The implementation of the system is based on the methods of Artificial Intelligence and utilisation of production systems and frame theory should be noted in this context. Finally a list of program modules and their characterisation is presented.

Computer-assisted recording of the objective neurologic finding.

Main principles of a computerized data collection system of the objective neurologic finding are presented. In the course of the findings recording, the physician communicates with the computer by an alphanumerical display in an interactive mode. The recording procedure is suggested by the computer program. The data are stored for further processing and are available as a narrative printout. The program uses a driving data structure of tree-like organized medical expressions with some control and formating parameters assuring medically correct procedures.

Changes in diagnosis in a 9-year national longitudinal sample.

Studied are changes in diagnosis in a random sample of 10% of all first admissions to psychiatric hospitals and psychiatric wards of general hospitals in Israel from 1983 to 1990 with follow-up evaluation to 1991. This included 4,570 hospitalizations of 2,220 patients. Data were extracted from the National Psychiatric Case Registry of the Ministry of Health. Almost 59% of the sample had one admission, 18% had two, 9% had three, and 14% had four or more. From the first admission to the last discharge (a mean of 2.15 years), 59.2% of the patients' diagnoses did not change. In 89.46% of the cases in which the diagnosis changed, the changes took place during the first admission. Diagnostic change differed between diagnostic groups. In descending order of stability in diagnosis from the first admission to the last discharge were neurotic and personality disorder (73.6%), mental retardation (73.5%), schizophrenia (73.0%), organic conditions (70.6%), affective disorders (66.2%), substance abuse (65.6%), childhood disorders (60%), paranoid disorder (43.6%), other nonorganic psychosis (30.3%), and V-codes (25.0%). The average level of diagnostic agreement between the first admission and the last discharge was a kappa of .52. The average length of stay for patients whose diagnosis became more severe was considerably longer than for patients whose diagnosis became less severe or did not change in level of severity. Older age was related to less change in diagnosis. For patients aged less than 18 years, diagnosis changed in 46.7% of the cases, for patients aged 19 to 44, 31.2%, and for patients older than 45, 27.8%.
