Enterprise architecture (EA) has been present in scientific literature since the 1980s and has branched out into several research fields. EA delivers value by presenting business and information technology leaders with recommendations for adjusting policies to achieve business goals. Although there are many works on the EA application in healthcare systems, the literature lacks studies that provide a systematic approach to this topic. This work presents a broad systematic literature review (SLR) to select studies demonstrating current EA practices in healthcare systems. The researchers established an SLR protocol returning 280 primary studies after the first step of the data selection and a consolidated inclusion of 46 articles after the second step. They assessed the level of disagreement during the team's evaluations using Cohen's Kappa. This SLR revealed essential aspects of state-of-the-art EA application in healthcare systems, such as the challenges, positive impacts, and critical success factors described by the studies' authors based on empirical approaches.

<p>Este trabalho teve como objetivo implementar uma solução de inovação tecnológica no Hospital das Clínicas da Universidade Federal de Pernambuco (HC-UFPE), utilizando uma abordagem com Gateway GSM, a partir de uma contratação pública, na qual foram locados equipamentos de telefonia IP. Como procedimento metodológico, realizou-se uma pesquisa aplicada, na modalidade de pesquisa-ação, na qual foi modificada a infraestrutura de telecomunicações do presente hospital para reduzir custos de telefonia, assim como melhorar o plano de contingência para este serviço e implementar tecnologia para a organização. Os materiais utilizados foram Gateway GSM com 16 canais para os 16 SIM’s <em>cards</em> (chips de celular) institucionais, um servidor Asterisk, e uma interface coaxial para interligar dois troncos E1, a central analógica/digital e o Asterisk. Como resultado, identificou-se que foi possível reduzir os custos com telefonia do hospital em aproximadamente 42%, incluindo o valor pago à empresa contratada, além de otimizar o plano de contingência de telecomunicações e agregar tecnologia na organização. Os achados deste trabalho podem contribuir com a redução de custos das empresas.</p>

The growing number of sick leave at work is a matter of concern in organizations. Recent researches show that a large part of these absences are related to Repetitive Strain Injuries (RSI) and Work-Related Musculoskeletal Disorders (WMSD), and that the performance of labor gymnastics (LG) at regular intervals during the employee's working hours can decrease the incidence of these diseases. The objective of this work is to present the contributions of the implementation of an open source LG software for the promotion of a healthier work environment, aiming at the prevention of RSI/WMSD. The methodology applied is a case study with an exploratory approach, with the voluntary participation of 23 employees from administrative sectors of a federal public hospital. The Nordic questionnaire was applied before the implementation of the LG software in order to identify musculoskeletal symptoms of the study participants, as well as a questionnaire to assess the possible benefits after 6 months of using the software in the corporate environment. As a result, it was possible to identify the acceptability of the software by the survey employees, as well as data on improvements in quality of life and in the work environment.
