I've been in practice 5 years, 3 years solo and we are 5th month into AC. We have 2,000 pts and have been scanning all of our paper charts. I want absolutely no paper charts to lug around. We have only about 10-15% of our charts remaining to be scanned.
Our old records (i.e. charts from outside doctor's offices) are almost never referenced. Therefore these are last priority. We have a lot of these and will eventually scan these in too. But these won't be done until later this year.
However, we've done similar to what other users discussed above. We pulled the charts apart and scanned everything into the Imported Items tab under the "Batch Import" folder. Each .PDF file is labeled as appropriate, i.e. labs are called "labs," imaging studies are called, "radiology," etc.
