The aim of my work was to find out the specific features of Czech medical reports in terms of the possibility of extracting specific information from them. For my work, I had a total of 268 anonymized narrative medical reports from two outpatient departments. I have studied standards for preserving electronic health records and for transferring clinical information between healthcare information systems. I have also participated in the process of implementing electronic medical record in the field of dentistry. First of all, I tried to process narrative medical reports using natural language processing (NLP) tools. I came to the conclusion that narrative medical reports in the Czech language are very different than a typical Czech text, especially because it mostly contains short telegraphic phrases and the texts lack typical Czech sentence structure. It also contains many misspellings, acronyms and abbreviations. Another problem was the absence of existence of the Czech translation of the main international classification systems. Therefore I decided to continue the research by developing the method for pro-processing the input text for translation and its semantic annotation. The main objective of this part of the research was to propose a method and support software for interactive correction...

Supervised machine learning models require a labeled data set of high quality in order to perform well. Available text data often exists in abundance, but it is usually not labeled. Labeling text data is a time consuming process, especially in the case where multiple labels can be assigned to a single text document. The purpose of this thesis was to make the labeling process of clinical reports as effective and effortless as possible by evaluating different multi-label active learning strategies. The goal of the strategies was to reduce the number of labeled documents a model needs, and increase the quality of those documents. With the strategies, an accuracy of 89% was achieved with 2500 reports, compared to 85% with random sampling. In addition to this, 85% accuracy could be reached after labeling 975 reports, compared to 1700 reports with random sampling.

Temos como pressuposto que para promover o restabelecimento de pessoas com transtornos mentais graves e reduzir o estigma é necessário desenvolver modos de cuidar em que a própria experiência da doença não seja negada. Por isso este trabalho foi apoiado na noção de recovery, que no cenário internacional tem contribuído para valorizar a dimensão da experiência do usuário. Para cumprir nosso objetivo, além de realizar uma revisão sobre o conceito de recovery, a fim de melhor compreende-lo, realizamos grupos focais com psiquiatras dos municípios de Campinas e Rio de Janeiro, e através desses grupos pretendemos acessar a experiência dos psiquiatras na formulação do diagnóstico de esquizofrenia e proposição do tratamento. Através do material produzido neste estudo pudemos perceber que a formulação do diagnóstico de esquizofrenia exerce grande impacto sobre a experiência de cuidar do usuário. E a concepção de esquizofrenia como doença grave e crônica parece influenciar amplamente o tipo de assistência que estes profissionais irão ofertar, assim como as expectativas que terão em relação à vida futura do usuário. A idéia de tratamento dos psiquiatras parece permeada não pela idéia de recovery, mas pelos princípios e objetivos da reabilitação psicossocial em seu sentido mais ortopédico e normalizante, que tem grande compatibilidade com o modelo biomédico, e oferece poucas ferramentas de acesso ao mundo e à experiência do usuário / Abstract: This master research is a qualitative multiside study, marked by the reference of phenomenology and hermeneutics, and aims to understand how psychiatrists of community-based mental health services deal with the dimension of the particular experience of people diagnosed as suffering from schizophrenia in the caring process. We have assumed that to facilitate the recovery of people with severe mental disorders and to reduce stigma is necessary to develop ways of caring in which the very experience of illness is not ignored. Therefore this work was supported by the notion of "recovery", which in the international arena has contributed to enhance the meaning of the user experience. To accomplish our goal, besides doing a review on the concept of recovery in order to better understand it, we conducted focus groups with psychiatrists from Campinas and Rio de Janeiro. In these groups we intended to access to the experience of psychiatrists in formulating diagnosis of schizophrenia and treatment proposition. Based on the material produced in this study, we realized that the formulation of schizophrenia diagnostic has a major impact on the experience of caring user. And the concept of schizophrenia as a chronic and severe illness seems to largely influence the type of care these professionals will offer, as well as the expectations they have regarding the future life of the user. The psychiatrists? idea of treating seems to be permeated not by the idea of recovery, but by the principles and goals of psychosocial rehabilitation in its most orthopedic and normalizing sense, which has great compatibility with the biomedical model, and provides few tools to access the world and experience of the user / Mestrado / Política, Planejamento e Gestão em Saúde / Mestre em Saude Coletiva
