Interoperability between information systems of the results of clinical analysis and electronic record of the patient

The issue of interoperability between institutions in underdeveloped countries always presents good opportunities for science to contribute to substantial improvements in real-world issues. Basic support systems, such as health institutions, are among those that can benefit most from scientific advances. This paper reports an analysis made on the lack of interoperability between health institutions, specifically with regard to the interaction between physicians' offices and clinical analysis laboratory. This research was validated with a real practical use case that is presented in this paper. In order to make the information stored in different computer applications of the health information system (HIS), more specifically in the Hospital Center Dr. Ayres de Menezes, in São Tomé and Príncipe, interoperable, two distinct applications were developed, Patient Management System (PMS) and Clinical Analysis Laboratory Management System (LMS) to implement interoperability between them. In this way, take advantage of the interoperability logic implemented between these two applications and later integrate other systems. The PMS requests medical exams through your Medical Consultation panel. The second system, LMS receives the exam request and after the exams are processed and validated, the results are sent to the requesting system. To make the interoperability service effective, the SOAP protocol was used, which allowed the exchange of information synchronously between these two applications, allowing for faster transactions of patients' pathological data, and greater confidentiality of this same information. And as the work progressed, we felt the need to create a functional prototype with REST to meet the cloud model proposal.A questão da interoperabilidade entre instituições em países subdesenvolvidos sempre apresenta boas oportunidades para a ciência contribuir para melhorias substanciais em questões do mundo real. Os sistemas de apoio básico, como as instituições de saúde, estão entre os que mais podem se beneficiar dos avanços científicos. Este trabalho relata uma análise feita sobre a falta de interoperabilidade entre instituições de saúde, especificamente no que diz respeito à interação entre consultórios médicos e laboratórios de análises clínicas. Esta pesquisa foi validada com um caso de uso prático real que é apresentado neste trabalho. De forma a tornar a informação armazenada nas diferentes aplicações informáticas do sistema nacional de saúde (SIS), mais concretamente no Centro Hospitalar Dr. Ayres de Menezes, em São Tomé e Príncipe, interoperáveis, foram desenvolvidas duas aplicações distintas, Sistema de Gestão de Pacientes (SGP) e Sistema de Gestão do Laboratório de Análises Clínicas (SGL) para implementar a interoperabilidade entre eles. Desta forma, aproveitar a lógica implementada entre estas duas aplicações e posteriormente integrar outros sistemas. O SGP solicita exames médicos através do seu painel de Consulta Médica. O segundo sistema, o SGL, recebe a solicitação dos exames e após os exames serem processados e validados, os resultados são enviados ao sistema solicitante. Para tornar o serviço de interoperabilidade efetivo, foi utilizado o protocolo SOAP, que permitiu a troca de informações de forma síncrona entre essas duas aplicações. Por outro lado, sentimos a necessidade de criar um protótipo funcional com REST para atender a proposta do modelo em nuvem

Architecture of a web-based DICOM viewer showing segmentations and simulations

In teleradiology doctors view the image data of a healthcare institution from a remote site. To do so they typically connect to an image repository, download the necessary data and finally view it in a locally installed DICOM viewer. Recent research activities in teleradiology [1, 2, 3, 4] focus on the implementation of ubiquitously accessible web-based DICOM viewers which simplify the access and the collaboration among radiologists. However, these solutions either have a weak performance, they run on the client side only, or they are not as feature rich as their desktop counterpart. In this contribution we present an architecture of a web based DICOM viewer which has both, good performance as well as advanced features such as the visualization of anatomical structures. On the client side only native web technologies are used. The whole architecture has been implemented and evaluated in the GoSmart environment, a planning tool for minimally invasive cancer treatment
