I'm currently working in an office that primarily serves elderly Hispanic patients. There's one doctor and the support staff. The doctor happens to be a technophile and converted the office to an EMR back in Nov. of 2007. There were a LOT of bumps along the way, but 18 months later, we have other doctors tour our office to see the way we've successfully integrated the EMR into the office workflow.
I started working here a year after the conversion, but I was the first IT-competent person hired since then (I wasn't even hired for IT purposes). As such, I've been able to significantly streamline office practices to the point where lab results are directly inserted into progress notes from Quest, the doctor gets real-time indications of patient insurance drug coverage while prescribing, ePrescribe capabilities which allow the doctor to send the Rx to the pharmacy while noting the medication in the progress note, fax records and progress notes directly from patient charts, etc. Pretty much any piece of paper that passes through the office (billing aside) gets scanned into the patient's chart. We do this both for ease of reference (easier to just pull up the high-quality TIFF than typing in a summary of a consult or diagnostic image) and for legal purposes. The doctor, contrary to some of the other comments, feels much safer legally having everything scanned, titled, timestamped and easily accessible. Oh, not to mention how much time is saved when we're subpoenaed for records and it takes the better part of 30 seconds to do a multi-doc fax.
The only real complaint I have with our EMR is its lack of ability to share records. We still have to fax records (certainly not snailmail!) and burn through reams of paper receiving records from other offices. I would love to see a connectivity standard between EMRs. That may be putting the buggy before the horse, though, with the lack of adoption we've been seeing in our area. Medicare's office a lot of incentive bonuses for using the EMR and ePrescribe, which are a lot more beneficial for early adopters, but still doctors seem to be dragging their feet. Maybe that'll change when they start seeing a 2% penalty tacked onto their Medicare payments in 2014?
