ROI

A few great case studies:

There are numerous studies showing that EHR has a significant ROI: http://content.healthaffairs.org/cgi/content/full/hlthaff.w5.10/DC1 http://content.healthaffairs.org/cgi/content/full/24/5/1103

For example, a detailed case study of the cost and quality benefits of EHR at Family Care of Concord, NH found net benefits per clinician per year of $30,324 https://www.acponline.org/atpro/timssnet/products/tnt_products.cfm?action=long&primary_id=330371070.

Another study of hospital-based provider order entry identified net savings of $1.7 million per year from drug dosing guidance, nursing time utilization, and error prevention http://www.jamia.org/cgi/content/full/13/3/261.

Studies show that there is benefit for health conditions like diabetes and heart disease from EHR http://www.pubmedcentral.nih.gov/articlerender.fcgi?tool=pubmed&pubmedid=15802479, http://www.ncbi.nlm.nih.gov/pubmed/18373141, and http://www.bmj.com/cgi/content/abstract/330/7494/765.

EHRs increase overall patient safety. Children's Hospital of Seattle, following best practices for implementation, have experienced a trend toward a lower mortality rate http://pediatrics.aappublications.org/cgi/content/abstract/118/1/290.

The level of medication error reduction with computerization of prescribing seen in multiple studies is over 80%
