Toward Application of Blockchain for Improved Health Records Management and Patient Care
Blockchain in Healthcare Today, 2019
Technological advancements have proven to be indispensable for improving patient care, yet they continue to present a host of problems. One of the most pressing concerns is how to improve quality of care while controlling costs. Beyond clinical care, one plausible solution is to share patient information freely and efficiently. Hospitals and clinics may share data internally, but external information sharing remains an issue. Despite the digitization of medical records, there remains a lack of adequate computing infrastructure or unwillingness to share data among providers. Care quality often suffers as a result. Implementing a type of peer-to-peer distributed digital technology, known as a blockchain, to record and transmit transactional data could be a solution to these concerns. Originally, blockchain was developed to record cryptocurrency transactions. However, as blockchain technologies have matured and adopted across dissimilar industries, the feasibility of possible applications of blockchain technology in healthcare is getting more attention. This article explores possible opportunities of adoption of blockchain technology to improve patient data security, privacy, and care while outlining the challenges that practitioners may encounter

Blockchain as a Foundation for Sharing Healthcare Data
Blockchain in Healthcare Today, 2018
Blockchain technology has the potential to transform healthcare delivery by facilitating data sharing between providers and electronic health record (EHR) systems. However, significant roadblocks stand in the way of widespread implementation of this technology across the healthcare industry. Our blockchain-based data-sharing solution addresses two of the most critical challenges associated with using blockchain for health data sharing: protecting sensitive health information and deploying and installing blockchain software across diverse hospital environments. Since transparency is a fundamental feature of blockchain, we enabled user-and group-based secret sharing by adding purpose-built software that leverages a collection of well-established cryptographic algorithms. To streamline deployment, we built a containerized solution that guarantees portability, simplifies installation, and reduces overhead maintenance costs associated with administration. To ensure ease of implementation in a hospital system, we designed our blockchain solution using a distributed microservices architecture that allows us to encapsulate core functions of our system into isolated services that can be scaled independently based on the requirements of a particular hospital system deployment. As part of this architecture, we built core components for securely handling cryptographic secrets, interacting with blockchain nodes, facilitating large file sharing, enabling secondary-index based lookups, and integrating external business logic that governs how users interact with Smart Contracts. The innovative design of our blockchain solution, which addresses critical data security, deployment, and installation challenges, provides the healthcare community with a unique approach that has the power to connect providers while protecting sensitive data
