MediLOT is an up-and-coming healthcare player in the blockchain industry.
On 5 June, Block Asia personally attended the Innovfest Unbound 2018 event hosted by National University of Singapore (NUS) to speak to the MediLOT representatives.
Luo Zhaojing, a PhD candidate from NUS, kindly granted Block Asia an exclusive interview with MediLOT.
Current Issues in Health Records
The current Electronic Health Record (EHR) provides data regarding a patient’s health and medical records such as admission and visit history, hospital discharge summaries and surgical or procedural history. While the it is essential in digitising data to help hospitals share information more efficiently, the EHR possesses certain shortcomings highlighted by MediLOT including privacy, accuracy in data analytics and security issues.
Luo explained, “For example, if a hospital wishes to collect a patient’s records from NUH, the information provided by NUH might not be fully precise. This is because the patient could have also patronised several other clinics or hospitals in between. Our solution is to provide an inter-institution data record through the blockchain system to help practitioners obtain full and accurate information.”
According to MediLOT, “By using a dual blockchain solution with a unique layered architecture, MediLOT platform is able to incorporate AI and Data Analytics capabilities on top of its control and data layers. This allows for machine learning APIs and complex applications to be built on top of MediLOT platform.”
Luo stated that MediLOT utilises blockchain to get a comprehensive medical data of patients to provide analytics. There are several components in the system, the first being data collection via blockchain to allow different hospital records to be admitted into the system. This is where the analytics comes in. Given a one-year data record prior, the system will be able to predict the severity of the patients’ conditions within the next few weeks and whether there will be a 30-day readmission.
With over five years of technological development, MediLOT has been collaborating with several hospitals for over three years, including National University Hospital (NUH) and Tan Tock Seng Hospital.
How it Works
Currently, MediLOT runs on a dual blockchain system. The LOT tokens are ERC20 tokens running on the Ethereum platform, while the other is an ongoing public blockchain that allows different hospitals to access cross-data.
Patients can enroll onto the MediLOT platform in hospitals and contribute their health and medical records in order to earn free LOT tokens. They will also be able to control access to their own personalised health records without having to rely on medical practitioners.
In order to obtain the patients’ medical records, hospitals will request for their consent and place bids using the LOT tokens to finally create insights and provide medical advice based on the information provided.
While blockchain is focused on transparency and accessibility, medical records are considered sensitive data. When asked about how MediLOT is able to continue providing security and privacy through blockchain, database systems and blockchain expert Zhou Xuxuan responded,
“The main point of blockchain is that it enables untrusted entities to share data. However, given that the patients’ data are very delicate, there will definitely be limited transparency. In the data itself, personal information will not be included.”
