Variables associated with suicide risk were collected from the files of 161 hospitalized psychiatric patients with a 10 year or greater history of illness. 84 patients were hospitalized due to suicide attempts and 77 had no previous suicide attempts or ideations. Suicide attempts were rated as medically serious suicide attempts (MSSA) or non-MSSA and used for training the systems. The ability of the neural networks was evaluated by screening the extremes of the suicidal spectrum (1) 54 records of patients who committed suicide and (2) 150 records of patients who never had suicidal thoughts. The records were taken from 3 hospitals, in various geographic regions in Israel. Neither neural network system is reliable in predicting suicide, however, records from one hospital, Gehah Hospital, were better identified than those from the two other hospitals (p < 0.05 for PPV; p < 0.01 for specificity). At present, neural networks are not reliable instruments for evaluating suicidal risk due to the significant number of false positive results. When low risk was indicated reliability was greater (NPV = 75.28%, specificity = 97.10% with ART; NPV = 91.76%, specificity = 95.12% with backpropagation). However, PPV, NPV and specificity rates of both systems achieved with Gehah Hospital records suggest that using a direct-subjective questionnaire may produce better results in the future.

Since the Internet is available worldwide, it can be of interest to define which of these tasks can be performed by means of some telepathology method based on it. This paper focuses particularly on the use of Internet multimedia electronic mail for exchanging multimedia cases. To test the validity of the proposed approach for transmission of multimedia cases, the first step is to evaluate its diagnostic accuracy. Trials involving the transmission of 299 cases have been carried out between two departments of Pathology in Italy (at the University of Udine and at the City Hospital of Trento, respectively) in order to evaluate the diagnostic accuracy as well as the time needed for acquisition and transmission. First results show that good diagnostic agreement can be reached, but the time needed for transmission, generally low, is not sufficiently affordable to be adopted in those cases where time is important. In particular, telepathology through multimedia e-mail can be adopted for second opinion consultation, remote image processing, quality assessment and continuing education possibly by means of software that integrates acquisition and delivery of cases with HIS functionalities.</p>","PeriodicalId":76132,"journal":{"name":"Medical informatics = Medecine et informatique","volume":"23 3","pages":"237-44"},"PeriodicalIF":0.0,"publicationDate":"1998-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3109/14639239809001404","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20698510","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
