Electronic Records and Healthcare Enterprise Informatics
As most other domains, healthcare computerization is going through revolutionary advances. All elements of modern healthcare systems must be connected with efficient and effective computer access and networks, providing useful and effective means for entering, processing and extracting information, including clinics and hospitals, emergency departments, operating rooms, clinical laboratories, pharmacy, radiation laboratories, patient care devices, patient care documentation, quality statistics, research & public health, IT infrastructure. The applications include patient electronic medical records, population health records, computerized medical billing, healthcare data organization, collection, storage, retrieval, and security.
Modern Electronic Health Record System Architecture should be designed for high availability, highly transactional, multiple geographically dispersed simultaneous users (including time zone issues). Data must be protected and comply with numerous security, safety and privacy regulations. User interface must be as easy and intuitive as possible. The systems must provide interoperability with multiple legacy and new systems - laboratory, radiology, financial, etc.
Subject to all safety, security and privacy regulations, the data must be accessible for research analytics which is revolutionizing the field of medicine.
This vast area of healthcare informatics presents ongoing challenges and opportunities. Presently, systems are fragmented in numerous dimensions. This vast complex system needs systems engineering to help stakeholders in planning, implementing and managing. Systems engineering elements include the identification of stakeholders, collection and management of interfaces and requirements, verifications, validation, training, and upgrading needs.
