RT Journal A1 Cresswell K, Sheikh A T1 ELectronic health record technology JF JAMA JO JAMA YR 2012 FD June 6 VO 307 IS 21 SP 2255 OP 2255 DO 10.1001/jama.2012.3520 UL http://dx.doi.org/10.1001/jama.2012.3520 AB While we agree with many of their points, we take issue with the claim that the benefits of EHRs are “well documented” because there is to date very little robust, generalizable evidence that investments in EHRs translate into direct short-term benefits to health professionals or patients.2 Our prospective evaluation of the implementation and adoption of England's National Health Service Care Records Service (national hospital-based EHRs) found that instead of improving care, this often resulted in considerable disruption to professionals' work flows and care provision. We found that it was this reality, rather than professional reluctance or resistance, that impeded effective integration.3
