re: Sharing Electronic Medical Records Still Too Hard
I'll add to your list of barriers for interoperability all day long, if you'd please show us just one clear path to smooth, reliable interoperability (within budget.)
Out of over 600 EHRs certified in 2011 for ambulatory clinics, less than 18 of them now certify for basic standards of interoperability. The reality is those disparate systems were not developed to work together in the first place. Therefore, any efforts for "interoperability" can only be a temporary fix. (Ie. "make-do" or "work-around")
Problematic, temporary fixes do not work in medicine.
At some point we'll have to give up the "jury-rigging" of current EHRs to adopt a more viable solution. A solution which is thoroughly planned & professionally developed from scratch. Essentially, it'd be what Epic has provided to the large hospitals, but for ambulatory medicine.
