  The development and adoption of Electronic Health Records (EHR) and health
monitoring Internet of Things (IoT) Devices have enabled digitization of
patient records and has also substantially transformed the healthcare delivery
system in aspects such as remote patient monitoring, healthcare decision
making, and medical research. However, data tends to be fragmented among health
infrastructures and prevents interoperability of medical data at the point of
care. In order to address this gap, we introduce BlockIoT that uses blockchain
technology to transfer previously inaccessible and centralized data from
medical devices to EHR systems, which provides greater insight to providers who
can, in turn, provide better outcomes for patients. This notion of
interoperability of medical device data is possible through an Application
Programming Interface (API), which serves as a versatile endpoint for all
incoming medical device data, a distributed file system that ensures data
resilience, and knowledge templates that analyze, identify, and represent
medical device data to providers. Our participatory design survey on BlockIoT
demonstrates that BlockIoT is a suitable system to supplement physicians'
clinical practice and increases efficiency in most healthcare specialties,
including cardiology, pulmonology, endocrinology, and primary care.
