The Strengths and Weaknesses of the HL7 FHIR Messaging Standard
It has been several years since we reviewed the progress of the HL7 FHIR standards adoption rate. Health Level Seven's (HL7) Fast Healthcare Interoperability Resources (FHIR) is an emerging standard that has rapidly captured the mind-share of the Health Information Technology (HIT) standards community. FHIR is a standard that enables healthcare data sharing between systems in a manner that is more easily implemented and more expressive than previous HL7 standards such as HL7 Version 2, 3 and Clinical Document Architecture (CDA). Regardless of the version of HL7 standard used, the purpose of these standards is to send clinical data in messages, whether to a party inside or outside your organization. HL7 devises flexible message formats so the receiver of the message can open it up, know who sent it and why, and break it down into understandable segments and data fields.

Why do EHR Firms Own Patient Data When Other Software Vendors Don't?
There's a healthy debate going on about healthcare data interoperability and I think the more we discuss it, the better off we'll be. It's absolutely crucial that all healthcare information systems be able to talk to each other in a way that is useful to both physicians/clinicians as well as patients. The only way to have truly interoperable systems is to have free (but safe and secure) data interchange and exchange requires access rights and an understanding of ownership rules. One part of the discussion that many vendors of electronic health records (EHRs), a large portion of the health IT ecosystem, don't want to have is about the ownership of patient data stored in "their" EHR systems.
