“…The lack of real-time access in interoperable systems was discussed in 6% (4/70) papers [ 13 , 40 , 70 , 71 ]. The inconsistency of data structures across heterogenous systems makes it difficult to ensure data integrity when data transfer is attempted across interoperable systems; 23% (16/70) papers indicated that blockchain could enhance data integrity across interoperable systems [ 16 - 18 , 33 , 35 - 37 , 40 , 41 , 44 , 49 , 64 , 66 , 72 - 74 ]. Furthermore, data transparency (which refers to the accessibility to data despite its location, data credibility, and data accuracy) across interoperable systems was discussed in 14% (10/70) papers [ 14 , 33 , 40 , 47 , 52 , 59 , 70 , 72 , 75 , 76 ].…”

“…The EMR differs from the EHR as it focuses on the internal medical domain of health organizations and is not integrated between health care providers. Blockchain’s use for EHRs, EMRs, and other record systems in which records are originated and controlled by providers was discussed in 51% (36/70) papers [ 11 , 14 - 21 , 27 , 29 , 30 , 33 , 35 - 37 , 40 , 42 - 44 , 46 , 49 , 53 , 55 , 59 , 60 , 63 , 67 , 68 , 72 - 74 , 76 - 78 , 84 ]. Using blockchain to integrate various health record systems (EHR, EMR, PHR, etc), mHealth, and telemedicine platforms can contribute to patient empowerment and patient engagement by providing a synchronized view of patient information to patients and health care providers, to support patient decision making and control.…”

Background Blockchain offers a promising new distributed technology to address the challenges of data standardization, system interoperability, security, privacy, and accessibility of medical records. Objective The purpose of this review is to assess the research on the use of blockchain technology for patient care and the associated challenges and to provide a research agenda for future research. Methods This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. We queried the Cumulative Index of Nursing and Allied Health Literature (CINAHL), PubMed, Excerpta Medica dataBASE (EMBASE), and Web of Science databases for peer-reviewed research articles published up to December 2019 that examined the implementation of blockchain technology in health care settings. We identified 800 articles from which we selected 70 empirical research articles for a detailed review. Results Blockchain-based patient care applications include medical information systems, personal health records, mobile health and telemedicine, data preservation systems and social networks, health information exchanges and remote monitoring systems, and medical research systems. These blockchain-based health care applications may improve patient engagement and empowerment, improve health care provider access to information, and enhance the use of health care information for medical research. Conclusions Blockchain health information technology (HIT) provides benefits such as ensuring data privacy and security of health data, facilitating interoperability of heterogeneous HIT systems, and improving the quality of health care outcomes. However, barriers to using blockchain technology to build HIT include security and privacy vulnerabilities, user resistance, high computing power requirements and implementation costs, inefficient consensus algorithms, and challenges of integrating blockchain with existing HIT. With 51% of the research focused on medical information systems such as electronic health record and electronic medical record, and 53% of the research focused on data security and privacy issues, this review shows that HIT research is primarily focused on the use of blockchain technologies to address the current challenges HIT faces. Although Blockchain presents significant potential for disrupting health care, most ideas are in their infancy.

BACKGROUND Blockchain offers a promising new distributed technology to address the challenges of data standardization, system interoperability and accessibility of medical records. OBJECTIVE The purpose of this review is to survey and analyze the current literature regarding the application of Blockchain technology in health care to broadly determine the Blockchain opportunities for patient care that health researchers are pursuing and the associated challenges. METHODS This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. We queried the Cumulative Index of Nursing and Allied Health Literature (CINAHL), PubMed, Embase, and the Web of Science databases for peer-reviewed research articles published up to December 2019 that examined the implementation of Blockchain technology in health care settings. RESULTS Applying a patient care focus, we identified three main categories of Blockchain research in health care: data privacy and security, interoperability and health care outcomes. Blockchain based health care applications include medical information systems, personal health records, mHealth and telemedicine, data preservation systems and social networks, health information exchanges and remote monitoring systems, and medical research systems. These Blockchain based health care applications may improve patient engagement and empowerment, health care provider access to information, and enhance the use of health care information for medical research. CONCLUSIONS Blockchain provides benefits such as ensuring the data privacy and security of health data, facilitating interoperability of heterogeneous HIT systems and improving the quality of health care outcomes. However, barriers for using Blockchain technology to build HIT include security and privacy vulnerabilities, user resistance, high computing power requirements and implementation costs, inefficient consensus algorithms and challenges of integrating Blockchain with existing HIT. Though Blockchain presents significant potential for disrupting health care, most ideas are in their infancy. Therefore, more research is needed to evaluate the impact of Blockchain technology post implementation.

“…Concerning the technical side, the criptography to protect the communications and the storage of medical data is gaining popularity in the eHealth domain. As an example, blockchain technology is a promising solution to face privacy and security concerns [ 26 , 27 , 28 ]. The Internet of Things have the potential to change the physical interaction between the individuals and organizations, aiming at exchanging information in a secure and reliable way through IT infrastructure [ 29 ].…”

Usability is key to achieve quality in software products. The client applications with a high score in usability might impact on the power consumption when they are run in a PC. For this reason, energy savings turn to be critical in green software systems. In this paper the relationship between the usability evaluations of the GUIs and the power consumption measurements of the main components of a PC were analysed. A set of 5 web-based personal health records (PHRs) were selected as a case study. The usability assessment was performed by an expert, employing the 14 principles of design by Alan Dix as heuristics. They were scored on a Likert scale after performing a collection of common tasks in the PHRs. At the same time, an equipment to measure the energy consumption of hard disk drive, graphics card, processor, monitor and power supply was used. Spearman’s index was studied for the correlations between the usability assessments and the power consumption measurements. As a results, some weak relationships were found. A total of 5 usability heuristics were observed to may influence energy consumption when they were considered in the implementation of the PHRs. These heuristics were the following ones: consistency, task migratability, observability, recoverability and responsiveness. Based on the results, the usability principles of design cannot always be related to lower energy consumption. Future research should focus on the tradeoffs between usability and power consumption of client applications when they are used in a computer.
