In general, up here the 3 relevant ISO certifications (around $45k to $80k each) that apply to e-record and diagnostic systems are required, or software cannot be legally purchased by the health authority. For many reasons, the e-record system software was written in partnership between a large telecom and Microsoft.

slicer.org has their detailed story why "3D Slicer is NOT FDA approved", and its unfortunate given the transient nature of volumetric imaging data formats.

My point was this area is a mine-field of regulation. Generally, the above rules trip the instant a doctor uses something to diagnose or communicate patient data. Notably, the same software is deployed across provinces and states... but will obviously have different certification requirements in each locale.

Some people seem to get really rude over the most mundane details. =3

It's kind of hilarious how some people with no real industry experience aren't able to do a simple search on the CHPL. Obviously, there's nothing illegal about using OpenEMR regardless of who wrote the code. And certification isn't even necessarily required. Providers who don't participate in certain federal or state programs are free to use non-certified software as long as they're able to comply with applicable interoperability and privacy/security regulations; regulatory compliance and enforcement for that stuff is at the provider organization level, not at the product level.

"there's nothing illegal about using OpenEMR regardless of who wrote the code"

Indeed, in your area this may be true. However, the health authority can't legally purchase or use these projects without the ISO certs, and thus it is a moot point.

I think we will have to agree to disagree, as there are two truths here. And people seem to be getting emotional about their egos. =)
