This textbook begins with an introduction to the US healthcare
delivery system, its many systemic challenges and the prior efforts
to develop and deploy informatics tools to help overcome those
problems. It goes on to discuss health informatics from an
historical perspective, its current state and its likely future
state now that electronic health record systems are widely
deployed, the HL7 Fast Healthcare Interoperability standard is
being rapidly accepted as the means to access the data stored in
those systems and analytics is increasing being used to gain new
knowledge from that aggregated clinical data. It then turns to some
of the important and evolving areas of informatics including
population and public health, mHealth and big data and analytics.
Use cases and case studies are used in all of these discussions to
help readers connect the technologies to real world challenges.
Effective use of informatics systems and tools by providers and
their patients is key to improving the quality, safety and cost of
healthcare. With health records now digital, no effective means has
existed for sharing them with patients, among the multiple
providers who may care for them and for important secondary uses
such as public/population health and research. This problem is a
topic of congressional discussion and is addressed by the 21st
Century Cures Act of 2016 that mandates that electronic health
record (EHR) systems offer a patient-facing API. HL7's Fast
Healthcare Interoperability Resources (FHIR) is that API and this
is the first comprehensive treatment of the technology and the many
ways it is already being used. FHIR is based on web technologies
and is thus a far more facile, easy to implement approach that is
rapidly gaining acceptance. It is also the basis for a 'universal
health app platform' that literally has the potential to foster
innovation around the data in patient records similar to the app
ecosystems smartphones created around the data they store. FHIR app
stores have already been opened by Epic and Cerner, the two largest
enterprise EHR vendors. Provider facing apps are already being
explored to improve EHR usability and support personalized
medicine. Medicare and the Veteran's Administration have announced
FHIR app platforms for their patients. Apple's new IOS 11.3
features the ability for consumers to aggregate their health
records on their iPhone using FHIR. Health insurance companies are
exploring applications of FHIR to improve service and communication
with their providers and patients. SureScripts, the national
e-Prescribing network, is using FHIR to help doctors know if their
patients are complying with prescriptions. This textbook is for
introductory health informatics courses for computer science and
health sciences students (e.g. doctors, nurses, PhDs), the current
health informatics community, IT professionals interested in
learning about the field and practicing healthcare providers.
Though this textbook covers an important new technology, it is
accessible to non-technical readers including healthcare providers,
their patients or anyone interested in the use of healthcare data
for improved care, public/population health or research.
