If EMRs are to successfully roll out to all physicians, physician information entry has to be faster than dictating. Only the technologically eager (like me) or the coerced (like my partners who bought the product) will spend more time doing medical record-keeping than they did before EMR implementation. Those physicians who have a choice will still dictate.
Of course, medication and diagnosis lists are the exception, once they are established. But these elements can arguably be quite time-consuming.
Wise EMR products put a little "dictate here" icon at various points in the EMR to capture a voice file, for those times when a story must be told.
