duffpkg's comment 2 years ago does not inspire great confidence in OpenEMR: https://news.ycombinator.com/item?id=40763424
>I was the main contributor and maintainer to OpenEMR about ~20 years ago and then decided it was irredeemable and started over with ClearHealth/HealthCloud. Shockingly some of my code code lives on (from PHP 3). I am reluctant to say don't use it but if you do please don't expose it to anything public, which sadly happens most of the time. There are some real problems that exist in that code base from a security and HIPAA perspective.
Finding SQL injections etc is definitely valuable, but at the same time they did not hack Epic; the "100000 medical providers" number links to https://www.hhs.gov/sites/default/files/open-emr-sector-aler... which links open-emr.org/blog/openemr-is-proud-to-announce-seamless-support-for-telehealth/ which...404s. Per archive.org the source is something the CEO of now defunct lifemesh.ai said.
"medical record software" makes it sound super serious, but again OpenEMR should not be taken as seriously as for instance Epic.
