Electronic Health Record: Blockchain Technology
Electronic health record (EHR) is a systematic
collection of compact real-time patient-centric information
which includes all types of treatments the patient has
undergone along with the lab results, medical prescriptions
etc.EHR allow faster sharing of records and information
retrieval.EHR is about helping the medical practitioners
provide quality treatment to their patients while also
maintaining the safety and efficiency of their records. But, one
of the exasperating problem that the health care systems face
is the ability to share medical records with more than one
stakeholders, while maintaining complete security and
ensuring data integrity. Storage and sharing of medical records
securely have been one of the important aspects of the
EHR.Medical data consists of sensitive information that the
patient expects to be kept confidential. At present, the biggest
issue of health care systems is the central administration of
data. Regardless of various advancements in the healthcare
industry, the EHRs have still been suffering from various data
breaches. Storing patients sensitive health records on the
Blockchain based storage can help in rectifying these
shortcomings. The Blockchain technology is decentralized and
a unique approach of storing data on a distributed network
without any central authority. The blockchain has the ability to
transform the healthcare industry, by placing the patient at the
center of the ecosystem and increasing quality, security,
interoperability of health records. Blockchain offers a set of
tools for solving many issues related to patients consent for
data sharing.Recent findings indicate that the blockchain
research has been increasing in the healthcare industry and is
mainly used for managing health records and access control.
