Medical software

As part of the ACA there is a requirement for all medical institutions to switch over to electronic medical records (EMR or EHR).  The theory is that too many mistakes were made due to sloppy handwriting and there was no communication between various offices which also led to mistakes.

Nothing is foolproof, but the EMR systems out there have to be very secure due to all of the healthcare related privacy laws.  I wouldn't get too worked up about them from a security standpoint, and focus on the benefits.  I do enjoy being able to schedule an appointment or check on test results online or via a phone app.

As for what software to use as a Doctor, you're husband will need to evaluate several different vendors to see which ones make the most sense for his practice.  There are a lot of factors that come into play such as what systems you currently use and what other offices you may be affiliated with.  If they're using software X, then you don't want to necessarily use software Y because it may not integrate as well.
