Este estudo descritivo / exploratório com análise documental, retrospectivo, utilizando o método de Estudo de Caso tem como objetivo avaliar o módulo de Gerenciamento de Unidade (PAGU) com foco no Prontuário Eletrônico do Paciente (PEP). No Complexo Hospitalar, campo de estudo, foi implantado o Sistema de Gestão Hospitalar em 2005. Iniciou-se com o levantamento da história da implantação do Sistema de Gestão Hospitalar seguindo seis fases: como primeira fase considerou-se o planejamento iniciado em 2002, seguindo para a fase de análise funcional com a determinação de rotinas, protocolos e processos operacionais; na fase de determinação de requisito avaliaram-se as necessidades da instituição em relação ao sistema, a fase do desenho e desenvolvimento foi realizada pela empresa contratada. A quinta fase constituiu-se a implementação. Como última fase considerou-se a avaliação do hardware e software realizada pelos responsáveis do Setor de Informática. Verificaram-se várias necessidades as quais foram atendidas, em parte, pela empresa contratada e outras, pelos responsáveis do setor de Informática do complexo hospitalar. O modelo proposto para avaliar o módulo PAGU baseou-se nas normas e padrões preconizados pela (ISO) International Organization for Standardization - (IEC) (International Electrotechnical Commission) 9126-4 Qualidade em uso. Para avaliar a realização das Prescrições Médica e de Enfermagem, selecionaram-se 45 e 35 usuários, respectivamente. Foram realizadas duas avaliações, sendo que entre a primeira e segunda foram implementadas melhorias que proporcionaram bons efeitos. Baseado nas normas ISO/IEC 9126-4 Qualidade em uso obtiveram-se os seguintes resultados: Métrica da Efetividade - a eficácia da tarefa realizada pelo segmento médico foi de 100% em ambas as avaliações, e 93% e 100% para o segmento Enfermeiro. Métrica de Produtividade - o tempo médio da realização da prescrição foi de 4,39 min na primeira e 6,21 min. na segunda avaliação para o usuário médico. O usuário enfermeiro obteve o resultado de 4,05 min. na primeira e 3,02 min. na segunda avaliação. O resultado da Métrica de Segurança do paciente relacionado à quantidade de itens prescritos com algum erro, pelo usuário médico, foi na primeira avaliação 1,94 e na segunda, 0,37 itens. O usuário enfermeiro resultou em 1,26 na primeira e 0,33 itens na segunda avaliação. Com respeito às falhas relacionadas à segurança, o usuário médico apresentou 1,84 itens na primeira e 0,32 itens na segunda avaliação, já o enfermeiro verificou-se 0,65 itens na primeira e 0,09 itens na segunda avaliação. Relacionado à economia obteve-se o valor de 0,13 na primeira e 0,09 itens na segunda avaliação para o usuário médico. O usuário enfermeiro obteve 0,99 itens na primeira avaliação e 0,24 na segunda. Na Métrica de Satisfação / Desempenho constatou-se o valor de 5,82 na primeira e 5,75 na segunda avaliação para o usuário médico e 5,58 na primeira e 6,41 na segunda avaliação para o usuário enfermeiro. Concluiu-se que a avaliação da realização da Prescrição, no módulo PAGU, atingiu respostas positivas na maioria das características. Os resultados obtidos neste estudo serão utilizados para ações de melhorias e treinamentos. Essa pesquisa proporciona a disseminação do conhecimento, em saúde e enfermagem / This descriptive, exploratory study with retrospective document analysis aims, using case study methodology, to evaluate the Management Unit module (PAGU) focused on the Electronic Health Record (EHR). The Hospital Management System was implemented in the Hospital Complex, field of study, in 2005. It began with a survey of the history of implementation of the Hospital Management System following six phases: the planning, which started in 2002, was considered the first phase. This was followed by the functional analysis stage with the determination of routines, protocols, and operational processes. In the requirement determination phase, the needs of the institution in relation to the system were evaluated. The design and development phase was carried out by the contractor. The fifth phase consisted of implementation. As a final step we considered the evaluation of the hardware and software comprising the I.T. systems. There were several needs which were met not only by the contractor but also by the staff responsible for the hospital\'s IT department. The model proposed to evaluate the PAGU module was based on norms and standards set by the (ISO) International Organization for Standardization - (IEC) (International Electro-technical Commission) 9126-4 Quality in use. In order to evaluate the performance of Physicians\' and Nurses\' Prescriptions, we selected 45 and 35 users, respectively. Two evaluations were carried out, and between them, improvements were implemented yielding positive effects. Based on ISO / IEC 9126-4 Quality in use, the following results were found: Effectiveness Metrics - the effectiveness of tasks performed by the physicians was 100 % in both evaluations, and for the nurses 93 % and 100 %. Productivity Metrics - the average time for completion of medical prescription was 4.39 min in the first evaluation and 6.21 min in the second for the physicians. The nurses obtained results of 4.05 min in the first and 3.02 min in the second evaluation. The result of the Patient Safety Metrics in relation to the amount of items prescribed with an error, concerning the physicians, was 1.94 items in the first evaluation and 0.37 items in the second. As for the nurses, this result was 1.26 items in the first evaluation and 0.33 in the second. With respect to security-related crashes, the physicians presented 1.84 items in the first evaluation and 0.32 items in the second, while the nurses\' result was 0.65 items in the first evaluation and 0.09 items in the second. In relation to economy, the values obtained for the physicians were 0.13 items in the first evaluation and 0.09 items in the second evaluation, while for the nurses these values were 0.99 items in the first evaluation and 0.24 in the second. In the satisfaction / performance metric a value of 5.82 was found in the first and 5.75 in the second evaluation for the physicians and 5.58 in the first evaluation and 6.41 in the second evaluation for the nurses. It was concluded that the evaluation of the performance of prescription module PAGU achieved positive responses relating to the majority of characteristics. The results of this study will be used for training purposes and quality improvement. This research provides the dissemination of knowledge in health care and nursing

Modeling Clinicians’ Cognitive and Collaborative Work in Post-Operative Hospital Care

January 2017 (has links)
abstract: Clinicians confront formidable challenges with information management and coordination activities. When not properly integrated into clinical workflow, technologies can further burden clinicians’ cognitive resources, which is associated with medical errors and risks to patient safety. An understanding of workflow is necessary to redesign information technologies (IT) that better support clinical processes. This is particularly important in surgical care, which is among the most clinical and resource intensive settings in healthcare, and is associated with a high rate of adverse events. There are a growing number of tools to study workflow; however, few produce the kinds of in-depth analyses needed to understand health IT-mediated workflow. The goals of this research are to: (1) investigate and model workflow and communication processes across technologies and care team members in post-operative hospital care; (2) introduce a mixed-method framework, and (3) demonstrate the framework by examining two health IT-mediated tasks. This research draws on distributed cognition and cognitive engineering theories to develop a micro-analytic strategy in which workflow is broken down into constituent people, artifacts, information, and the interactions between them. It models the interactions that enable information flow across people and artifacts, and identifies dependencies between them. This research found that clinicians manage information in particular ways to facilitate planned and emergent decision-making and coordination processes. Barriers to information flow include frequent information transfers, clinical reasoning absent in documents, conflicting and redundant data across documents and applications, and that clinicians are burdened as information managers. This research also shows there is enormous variation in how clinicians interact with electronic health records (EHRs) to complete routine tasks. Variation is best evidenced by patterns that occur for only one patient case and patterns that contain repeated events. Variation is associated with the users’ experience (EHR and clinical), patient case complexity, and a lack of cognitive support provided by the system to help the user find and synthesize information. The methodology is used to assess how health IT can be improved to better support clinicians’ information management and coordination processes (e.g., context-sensitive design), and to inform how resources can best be allocated for clinician observation and training. / Dissertation/Thesis / Doctoral Dissertation Biomedical Informatics 2017

Sistema informartizado para gestão de casos clínicos psiquiátricos / Computerized system for psychiatric clinical case management

Lucas Romeiro Pellozo 14 June 2016 (has links)
A grande quantidade de informação e conhecimento, armazenada nos casos clínicos médicos documentados, gera a necessidade de recuperar, relacionar e categorizar essa informação para a geração de conhecimento através de pesquisas e para melhoria de treinamento e tratamento médico. Na área da saúde, especificamente Psiquiatria, os casos clínicos apresentam determinantes multifatoriais biológicas e sociais. Pela característica multifatorial, os casos são complexos e evidências importantes podem passar despercebidas para estudo, análise e auxílio a diagnóstico. Dentro da Psiquiatria, outro fator importante é a forma como os diagnósticos relacionados à Esquizofrenia e outros transtornos psicóticos (EOP) são feitos: trata-se de uma entrevista clinica estruturada que exige uma complexidade para aplicação e gera uma grande quantidade de informação. Nesse cenário, inundado de conhecimento espalhado, este trabalho tem o objetivo de apresentar um sistema informatizado com a função de realizar a entrevista clínica de forma informatizada, assim como a recuperação, relacionamento e categorização dos casos clínicos. Permite também a busca dos casos baseados em similaridade de conteúdo textual, através de técnica de similaridade baseada em raciocínio de caso. O sistema foi testado com uma base de dados previamente montada por especialistas e validado na sua perspectiva clinica e de pesquisa através da utilização em um cenário real, com casos reais. Para uma validação voltada a uma perspectiva de expansão e comercialização deste tipo de sistema foi feita uma avaliação através da perspectiva de inovação e novos negócios, o que se alinha com as metas nacionais de inovação em softwares e a transferência tecnológica das universidades para o atendimento da população. Por fim, foi demonstrado que esse sistema tem potencial para se tornar um gerador de conhecimento e apontamento de informação de fina relevância para auxiliar e acelerar treinamentos e tratamentos na área da saúde tendo impacto direto na formação dos profissionais dessa área e consequente melhoria no atendimento feito por eles. / A large amount of information and knowledge, stored in documented medical clinical cases creates the necessity to retrieve, categorize and relate that information to generate knowledge through research and to improve training and medical treatment. In the Health area, specifically Psychiatry, clinical cases have multifactorial biological and social determinants. Because of multifactorial feature, cases are complex and important evidence can be missed for study, analysis and aid the diagnosis. Another important factor is how the diagnoses related to schizophrenia and other psychotic disorders (EOP) are done: it is a structured clinical interview which requires a complexity to application and generates a lot of information. In this scenario, full with Spread Knowledge, this project aims to introduce a computerized system with the function to perform the clinical interview computerized form, As the Recovery, Relationship and categorization of Clinical Cases. Also it allows the pursuit of cases based on textual content similarity, through technique of reasoning based on similarity Case. The system was tested with database pre-assembled and validated by experts in their clinical and research perspective through the use of a real scenario with real cases. For a more focused assessment with a view to expansion and commercialization of this system, an evaluation through innovation perspective and new business, this is in line with national goals of innovation in software and technology transfer from universities to meet the population. Lastly it was demonstrated that this system has the potential to become a generator of knowledge and information for fine pointing relevance to assist and accelerate training and treatments in healthcare with a direct impact on training of professionals in this area and consequent improvement in treatment done for them.

Acceptance and Usage of Electronic Health Record Systems in Small Medical Practices

Tannan, Ritu 01 January 2011 (has links)
One of the objectives of the U.S. government has been the development of a nationwide health information infrastructure, including adoption and use of an electronic health records (EHR) system. However, a 2008 survey conducted by the National Center for Health Statistics indicated a 41.5% usage of the EHR system by physicians in office-based practices. The purpose of this study was to explore opinions and beliefs on the barriers to the diffusion of an ERH system using Q-methodology. Specifically, the research questions examined the subjectivity in the patterns of perspectives at the preadoption stage of the nonusers and at the postadoption stage of the users of an EHR system to facilitate effective diffusion. Data were collected by self-referred rank ordering of opinions on such barriers and facilitators. The results suggested that the postadoption barriers of time, change in work processes, and organizational factors were critical. Although the time barrier was common, barriers of organizational culture and change in work processes differed among typologies of perspectives at the postadoption stage. Preadoption barriers of finance, organizational culture, time, technology, and autonomy were critical. The typologies of perspectives diverged on critical barriers at the preadoptive stage. A customized solution of an in-house system and training is recommended for perspectives dealing with technical and organizational concerns and a web-based system for perspectives concerned with barriers of finance, technology, and organization. The social impact of tailoring solutions to personal viewpoints would result in the increased sharing of quality medical information for meaningful decision making.

Essas informações são geradas em razão dos serviços de atenção à saúde e são os insumos que diariamente alimentam os sistemas de informações do Ministério da Saúde/DATASUS. Os Sistemas de Informações em Saúde (SIS) configuram-se como mecanismos de transferência de informações para a gestão em saúde, no entanto, vários problemas podem ser diagnosticados quanto à utilização desses sistemas: produção de informações de baixa qualidade e subutilizadas, duplicação de sistemas de informações de forma verticalizada e não-integrada, dificuldades quanto à retroalimentação desses sistemas. Percebe-se que as informações que alimentam esses SIS possuem um viés meramente para fins estatísticos e na maioria dos casos, a utilização desses SIS pelos gestores em saúde é feita de forma compulsória. Neste contexto, o objetivo desta pesquisa é verificar se os mecanismos de transferências de informações dos hospitais convergem com as diretrizes da Política Nacional de Informação e Informática em Saúde (PNIIS) e do Plano de Desenvolvimento para a nformação e a Tecnologia da Informação em Saúde (PlaDITIS). Para tanto, são identificadas as fontes e os mecanismos de transferência de informações utilizadas nos organismos de serviços de saúde e, se estas estão em conformidade com estas diretrizes. O arcabouço teórico, metodológico da pesquisa procurou ressaltar a importância da PNIIS e o PlaDITIS para uma gestão integrada, acesso e uso da informação e da tecnologia da informação na definição das políticas de saúde. A pesquisa é exploratória e descritiva com uma abordagem quali-quantitativa. A população para a realização desta pesquisa são 39 hospitais com termo de adesão à Rede de Inovação e Aprendizagem em Gestão Hospitalar. Para o levantamento dos dados utilizou-se como instrumento o questionário e o roteiro semi-estruturado para a entrevista, com a finalidade de alcançar os objetivos propostos. O tratamento dos dados foi realizado por meio da estatística descritiva e análise de conteúdo. Os resultados revelam a necessidade da disseminação das políticas de informação e informática e a necessidade da difusão do uso de mecanismos de transferência de informações entre os organismos prestadores de serviços de atenção à saúde no Brasil. / ABSTRACT - Health information in Brazil constitute a complex and diverse picture of the reality of health and support the deliberations for the management of the unified health system (SUS).This information is generated as a result of health care services and are the inputs that feed the information systems of the Ministry of health/DATASUS. Health Information systems (SIS) configure themselves transfer mechanisms for information management in health, however, several problems can be diagnosed on the use of these systems: production of low-quality information and under-utilized, duplication of information systems of vertical and non-integrated form, difficulties with regard to the feedback of these systems. You understand that the information that feed these SIS have a bias merely for statistical purposes and in most cases, the use of SIS for health managers is compulsory. In this context, the objective of this research is to verify if the information transfer mechanisms of hospitals converge with the guidelines of the national information Policy and health informatics (PNIIS) and the development plan for the information and information technology in health (PlaDITIS). Are identified the sources and information transfer mechanisms used in health services organizations and, where these are in accordance with these guidelines. The methodological research, sought to highlight the importance of PNIIS and PlaDITIS for integrated management, access and use of information and information technology in the definition of health policies. The research is exploratory and descriptive with a quali-quantitative approach. The population for this research are 39 hospitals with term of membership of the learning and innovation network in hospital management. To survey the data used as a tool the questionnaire and semi-structured interview script, in order to achieve the proposed objectives. The treatment of the data was performed by descriptive statistics and content analysis. The results reveal the need for dissemination of information and informatics policies and the need for the dissemination of the use of mechanisms for information transfer between agencies providers of health care in Brazil.

On the first chapter we jut out with details these scientific and ideological movements, on a wider way, but also on the specificities of the public health s information politics. On the second chapter we analyze the downward health information circle at the basic care, observing the operational processes of the information s technical systems SIAB and e-SUS. On the third and last chapter, we give references to think about an upward health information circle, centered on the places, ruled by the notions of autonomy, organic solidarity and communicational density. It would possess, as method s primary horizon, the local organization of production and managing of information through the work of the Health Community Agent, privileging therefore the urgency of the most contingent needs of the people in theirs every day s life / Atrav?s da an?lise da atividade informacional na aten??o B?sica do SUS, ou seja, na escala do lugar, esta disserta??o tem como objetivo central observar a disputa pelo conceito de sa?de e de doen?a no ?mbito da sa?de brasileira, destacando, de um lado, o pensamento cl?nico, biom?dico ou flexneriano hegem?nico, cientificamente restrito e principal quadro de refer?ncia da pol?tica de sa?de no Brasil e do outro lado uma multiplicidade de novas propostas e pensamentos cr?ticos ao modelo vigente que possuem como ponto comum a preocupa??o com a sa?de no contexto supra-biol?gico e, portanto, territorial.

Inicialmente, através de uma revisão narrativa da literatura, a pesquisa traz uma discussão teórica sobre os conceitos centrais da pesquisa (Deficiente Visual, Acesso à Informação e Promoção da Saúde), e sobre os fatores de suporte no acesso à informação pelo deficiente visual (Suporte Cognitivo, Suporte Social e Suporte Tecnológico). Em uma segunda etapa, através da Revisão Sistemática da Literatura (RSL) e da Meta-Etnografia, foi realizado um levantamento de evidências de dificultadores e facilitadores no acesso à informação. As evidências foram classificadas em oito categorias, de acordo com a responsabilidade atribuída a esses fatores. A terceira etapa teve como objetivo específico avaliar a potencialidade das ferramentas tecnológicas de redes sociais para o suporte social do deficiente visual. Para tal, foi realizado um estudo de caso quantitativo exploratório no grupo Low Vision do Facebook, utilizando a técnica de Análise de Redes Sociais (ARS). Os resultados gerais da pesquisa apontaram para um conjunto variado de fatores intervenientes no acesso à informação, de caráter multidisciplinar, sobrepostos e interrelacionados. Aspectos de natureza social foram percebidos como os mais frequentes segundo a revisão sistemática. O estudo de caso apontou para dezesseis categorias temáticas de assuntos existentes, e para uma rede social relativamente densa no suporte oferecido, em comparação com os padrões de comportamento de ambientes da Web. O suporte oferecido é mais frequente, mas promove menor interação com os usuários em relação ao suporte solicitado. O suporte do tipo instrumental apresentou resultado similar ao suporte oferecido, uma vez que foi mais frequente, porém resultou em relações menos abrangentes e intensas. A pesquisa apontou para a necessidade de avaliar a dinâmica dos fatores intervenientes no acesso à informação, e o grau de impacto causado na qualidade de vida do deficiente visual. As ferramentas de redes sociais podem ser importantes canais para a promoção da saúde por meio do suporte social. A análise de redes sociais mostrou-se uma técnica importante para análise das trocas de informação em ambientes digitais para o suporte social. / The following study aims to analyse the factors that enable and hinder the information access by visually impaired individuals, which affect their quality of life. Initially, by means of a narrative literature review, this research brings a theoretical discussion about this work’s core concepts (Visually Impaired Individual, Access to Information, Promotion of Health) and also the supporting factors in the access to information by the visually impaired (Cognitive Support, Social Support, Technological Support). During a second phase, by means of a Systematic Review of Literature (SRL) and also Metha-Etnography evidence regarding enabling and hindering factors was gathered. The data was then arranged in eight categories, according to the responsibility attributed to these factors. The third phase had the specific goal of evaluating the potential of social networks to be a support for visually impaired individuals. In order to do so, a quantitative exploratory case study of the Facebook group Low Vision was carried out, by means of the Social Network Analysis technique (SNA). The overall results of the research point to a diverse combination of multidisciplinary, juxtaposed, interrelated factors, which interfere in the information access. According to systematic review, social aspects have been found to exist as the most frequent. The case study has pointed out to sixteen themed categories of existing topics, as well as to a relatively dense social network surrounding the support offered, in comparison patterns of behavior in Web (online) environments. The support offered is more frequent, but promotes fewer interactions with users in relation to the support requested. The instrumental type of support has presented similar results in comparison to the support offered, since it has been more frequent. However, it resulted in relationships that were less broad and less intense. The research has pointed the need to evaluate the dynamics of intervening factors in information access, and the extent of the impact caused in the quality of life of the visually impaired. The tools provided by social networks may be important channels for the promotion of health by means of the provision of a social support group. The analysis of social networks has shown itself to be an important technique for the analysis of information exchanged in online environments for social support.
