Patient health data are stored in disparate silos—separate islands of information residing in often incompatible EMR/EHR and PHR databases controlled by different hospitals, clinics and public health agencies, as well different group and solo practices. The question is: What is the best way for this personal health information to be shared securely between the people who need it to provide quality care to individual patients, protect populations, and perform research leading to valid evidence-based guidelines?
There's actually a simple, inexpensive and secure way to exchange data between any PHRs, EHRs, EMRs and public health/research/biosurveillance databases. As I've discussed in previous posts, it requires a paradigm shift from...
- Monolithic, centralized, pull, synchronous systems—an architecture that's good behind an organization's firewall
- Distributed federation of asynchronous pub/sub nodes that push data from publishing to subscribing nodes—an architecture that's good for the kind of loosely coupled P2P networks crossing organizational boundaries that comprise the NHIN (National Health Information Network).
- Data slicing, dicing and drilling down (i.e., breaking a body of information down into smaller parts, examining it from different viewpoints and dividing an information area up into finer and finer layers)
- Switching from lists and tables to graphs
- Answering ad hoc "what if" questions
I discuss this solution in detail at this at my company's LinkedIn group at http://www.linkedin.com/groups?home=&gid=2697006&trk=anet_ug_hm&goback=%2Eanh_2697006. You're welcomed to join.
