Cost of the hardware, network infrastructure, storage, backup and data retention (7 years? 10 years? I don't know HIPPA reqs), redundant data center power, redundant data center cooling, plus smart people to do all that stuff? Somewhat more than Nil.
Plus, smart people to look at the Xrays and say "Yep, it's broken" or "Yep, it's broken but HERE is a larger issue" ... more than Nil, as well.
Don't get get me wrong - I'm not a fan of hospitals charging $50 for an asprin. But, I think that it's inaccurate for people to assume that all of the behind the scenes stuff that happens should be free, too.
” $50 for an asprin”
The aspirin is $50 because of all the paperwork needed to procure it; store it; and keep records of it, etc.
That is due to everyone getting sued. The real answer is all the lawsuits that happen in medicine.
