A very thought provoking post this morning by John. http://www.emrandhipaa.com/emr-and-hipaa/2012/07/05/what-saas-ehr-users-can-learn-from-the-megaupload-takedown/?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+EmrAndHipaa+%28EMR+and+HIPAA%29
Everything is relevant, including all the concerns.
Isn't everything pegged against cost? One reason why we choose web based EHR is because we don't want the headaches. Why do top fortune 50 companies choose Salesforce.com?
Data backup is a kind of 'insurance' policy that can be bought. I don't see a reason why not. The question is, how much are you willing to pay.
I do agree that SaaS EHR companies should offer that 'insurance' of data backup and allow customers to decide if they want to buy.
