Abstract
The use of electronic health records (EHR) to support clinical practices is widespread worldwide, due to the need to optimize health care delivery. Therefore, the usability assessment of EHR systems is crucial. The objective of this study was to perform a qualitative and quantitative assessment of the usability of SClinico, the most used EHR system within the Portuguese National Health Service. This observational study to assess SClinico usability took place in several clinical services of the Centro Hospitalar de Trás-os-Montes e Alto Douro. The results show that SClinico has some usability issues that influence the clinical practice and, therefore, need to be improved. Copyright

Abstract
Venous thromboembolism is a pathology that is responsible for high rates of morbidity and mortality in hospitals. An adequate thromboprophylaxis may contribute to an effective improvement of the well-being and safety of patients. One of the important factors for the prescription of a thromboprophylaxis is the determination of the risk of thromboembolism, which can be implemented in several ways, using different methodologies, namely by using risk scales. In this work, developed in the Hospital Center of Tras-os-Montes and Alto Douro, Portugal, we describe the development and implementation of an application with two scales for the assessment and stratification of the risk of thromboembolism, to be applied in hospitalized patients (Caprini scale) and in patients in ambulatory surgery (scale recommended by the Portuguese Ambulatory Surgery Association). The application was integrated into the hospital electronic health record system (SClinico).

Abstract
The use of electronic health records to support health activities is currently quite widespread, due to the increasing complexity of health care and the need to optimize human and material resources. The requirement of health care professionals to access clinical information expeditiously is a key factor in the quality of health care services. Therefore, the assessment of the usability of the health of applications is crucial. The objective of this study was to evaluate the usability of SClinico through a questionnaire especially developed, and it took place in an hospital environment. The SClinico is an electronic health record application used on a large scale in public Portuguese healthcare institutions. The results show that SClinico has some usability issues that need to be improved. Among these we highlight the need to take a holistic view of the patient's health record and simultaneously quick access to relevant details for different clinical situations.
