Hi Denise, Thanks for this analysis. I would have love to have a comment of you to support this finding. Like Alok Prasad, I found an interesting web that explains the differences between EHR and EMR and how the market uses them : http://www.softwareadvice.com/articles/medical/ehr-vs-emr-whats-the-difference/ However, to add to your work, I looked in the Pubmed medical literature database when these terms were used for the first time (according to pubmed mesh and keywords recordings. Have a look at my blog to see the results : http://dcisante.blogspot.com/2010/01/pubmed-search-of-emr-ehr-and-phr-terms.html Regards, Adam Mohammed Selamnia
