Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / In despite of the great advantages of adopting computer systems for storing patient's information in hospitals and clinics, such systems are adopted with restrictions in these institutions. Some studies indicate that the rejection of such systems by the clinicians is greats due to computing not consider the particularities of the activities performed by the user in the clinical field. Considering this background, the project ClinicSpace aims to build a prototype tool to help health professionals in performing of their activities, using concepts and technologies of ubiquitous computing, which suggests that the computation must be fully integrated into the environment, disappearing from the user's consciousness and assisting him in their daily activities. This paper proposes an architecture called pEHS - Pervasive Electronic Healthcare System - a electronic health system inserted in the ClinicSpace's proposal, where the computing is oriented to clinical activities and the applications do interact with the ubiquitous environment through context information. The contribution of this paper is the proposal of a new software architecture in which pEHS modular applications follows the medical activities, making the system to adapt to the clinician's activities. In the architecture there are two points in evidence: the possibility of access to any information from the patient's health history and the adaptation of pEHS applications to the context information at runtime. The prototyped architecture will be used in the ClinicSpace project to build the applications needed for the clinicians helping them to carry out their activities. / Apesar das grandes vantagens existentes na adoção de sistemas computacionais para armazenamento das informações do paciente em ambientes hospitalares, tais sistemas são adotados com restrições em hospitais. Estudos indicam que a rejeição destes pelos clínicos é grande devido à computação não levar em consideração as características das atividades desempenhadas pelo usuário e sua forma particular de o fazê-lo. Tendo em vista essa necessidade, o projeto ClinicSpace tem por objetivo prototipar uma ferramenta para auxílio ao profissional de saúde na realização de suas atividades, utilizando conceitos e tecnologias da Computação Ubíqua, a qual propõe que a computação deve ser totalmente integrada ao ambiente de forma a desaparecer da consciência do usuário e auxiliá-lo na realização de suas atividades diárias. Este trabalho propõe uma arquitetura chamada pEHS Pervasive Electronic Healthcare System sistema eletrônicos de saúde inserido na proposta do ClinicSpace, onde a computação é orientada a atividades clínicas e as aplicações interagem com o ambiente ubíquo através das informações de contexto. A contribuição deste trabalho é uma proposta nova de arquitetura de software na qual as aplicações modulares do pEHS acompanham as atividades médicas, fazendo com que o sistema adapte-se às atividades do profissional. Destacam-se dois pontos da arquitetura:a possibilidade de acesso a qualquer informação do histórico de saúde do paciente e a adaptação das aplicações pEHS às informações de contexto em tempo de execução. A arquitetura prototipada será utilizada no andamento do projeto ClinicSpace para a construção das aplicações necessárias aos profissionais de saúde para a realização de suas atividades de forma personalizada.

The future of healthcare is increasingly digital, which includes a shift towards more personalised services that allow for more patient-centred and transparent patient care. These services are defined as PeHS and although there are great potential benefits of these services, there are also challenges regarding infor[1]mation security and privacy related to providing this type of services. This thesis project aims to examine the state of ISMS related to PeHS, which would also involve an examination of considerations taken regarding privacy in PeHS. The data collection methods for this thesis project were a systematic literature review and qualitative interviews.In total 18,667 publications published between 2017 and 2022 were found during the database searches. When the selection criteria had been applied 17 publications from the search process and 1 publication from the backward snowball process were accepted. The accepted publications were analysed by applying thematic analysis. Furthermore, two interviews with three participants were conducted after the literature review had been completed. The interview material was analysed by applying the analysis method of qualitative content analysis. The results showed that there are several challenges regarding ISMS and privacy related to PeHS. For example, there is a lack of knowledge within the organisations on why they should be applying the methods and tools available to ensure the security of the information flow through the healthcare services. Another example is the challenge of keeping up with the pace of digitalisation and adjust the ISMS to ensure sufficient information security of the services.
