Security and immutability of open data in healthcare

Clinical data are sensitive data given the origin of the information. Since the implementation of health information systems, some issues such as interoperability, security, and privacy have been strongly questioned. Storing and consulting them raises the same concerns. Given these concerns, any attempt to introduce healthcare information systems must guarantee the security and privacy, integrity, and immutability of patient information. It is in this sense that blockchain technology and the openEHR open data model appear, as they manage to guarantee interoperability between systems, data security and guarantees about queries of each stored data. In order to understand how to increase security and immutability in an implementation of open data models in hospitals, two distinct architectures were developed. In these architectures, several performance tests were carried out. To understand which of them represents more value to a health institution, an analysis of the results was prepared and, consequently, a discussion about them was held to be able to draw the respective conclusions.(undefined

An OpenEHR adoption in a portuguese healthcare facility

The quality and safety of clinical decisions depend to a large extent on the knowledge acquired by the records of health professionals. However, a traditional Electronic Health Record (EHR) has become insufficient in terms of knowledge acquisition and clinical decision support. The development of these aspects may bring marked improvements in the quality and safety of health care. The usage of open models promotes interoperability between systems, minimizing the impact of information systems on the efficient production of knowledge useful for clinical decisions. In this sense, this article describes an implementation project of a system that support the production and use of knowledge in clinical environments, based on OpenEHR two levels modelling open data approach, in a healthcare facility on the north of Portugal.he work has been supported by FCT – Fundação para a Ciência e Tecnologia within the Project Scope: UID/CEC/00319/202

Permissioned blockchain approach using open data in healthcare

Digital health records play a key role in the area. However, it is difficult to obtain a unified view of your data, as it is distributed among different providers, spread over several places, and is not integrated. To address these problems, blockchain technology and the openEHR interoperability standard have emerged. Blockchain is a new wave of disruption that has come to redesign interactions that involve any form of exchange of values, with the potential to improve healthcare, bringing a new perspective on security, resilience, and effectiveness of systems. In turn, with the use of openEHR, the standardization of electronic records is guaranteed, offering fine-grained access permissions for stakeholders. In addition to the use of archetypes as a reference to make the templates, where they are integrated to build a module with compatible standards. Based on an open data framework, OpenEHR, and blockchain technology, this paper has conceptualised a proposed two architectures that will be implemented within a Portuguese hospital, at the ICU, to increase and provide support for clinical decision-making, ensuring interoperability between systems, as well as the veracity, privacy and security of the data being used.FCT -Fundação para a Ciência e a Tecnologia(DSAPI A/DS/0084/2018

Clinical workflows based on OpenEHR using BPM

The integration of clinical workflows in electronic health records systems has been problematic due to the complex nature of clinical processes. For that reason, many health institutions have opted to maintain a few clinical workflows on paper, which has been compromising the quality and efficiency of several provided services. The purpose of this study is to investigate if the OpenEHR model can be applied in the configuration and management of clinical workflows using Business Process Modelling (BPM), with the focus on clinical forms based on OpenEHR archetypes and having has background the institution Centro Hospitalar do Porto (CHP). The need to review the workflows is pertinent due to the lack of integration of clinical workflows on their Electronic Health Records system. To analyse this possibility, a prototype was created containing: i) a BPM tool to configure and manage the clinical workflows; and ii) a web application to execute them and call the external clinical forms. The obtained results proved that the use of a BPM tool to configure clinical workflows allows the interoperability and flexibility of the prototype, which helps to improve the quality and efficiency of the clinical practice.This work has been supported by FCT – Fundação para a Ciência e Tecnologia within the Project Scope: UID/CEC/00319/2019
