As I wrote what seems like an age ago, concern over medical errors is exaggerated, but of those errors that do occur, a substantial amount (I cannot remember the figure) relates to inability to read or understand other people’s notes. Computerization of medical records would presumably eliminate that source of error, and is therefore a good thing. I’m not sure why insurance companies haven’t insisted on it, but my guess (and I stress it is a guess) would be some regulations related to privacy, which was the source of the AMA and ACLU’s opposition in the past.
