This is an excellent presentation of errors and potential errors in these systems. I am a Physician and involved in Program development. The system a hospital I work in is so full of errors that it is frightening. There is nobody to tell, and no remedy. In the past, an attempt at pointing these out only resulted in the simple answer "there is nothing wrong". Thus implying that the error was "in the chair" (meaning user). We have problems as basic as every page has a nonfunctional tab order. We have the same problem with ordering of medication doses as well as IV and PO intermingled. The only potential advantage we could gain from these systems which waste time, and create huge error risks would be interoperability. Where I am on the East Coast, this is not even a consideration. Every system has its own proprietary database and they do not want to share with anyone. Will these systems ever achieve anything Meaningful??? At this point in time they should be labeled "Meaningless Junk". They need to be designed from the ground up by Physicians (who are not simply self appointed experts but actually understand the programming issues). Many of the problems noted in the talk are attributable to an evolution from Legacy Systems built around billing to current EMR. This we see is a prescription for poor functionality and a great deal of potential errors.
