I am surprised nobody is using the Tracked Data/Flowsheets section, under the Summary Sheet tab. It seems like it would work just fine. New colonoscopy comes in. You can open chart, go to Summary Sheet tab, and add a row in the Tracked Data/Flowsheets section that says today's date, "colonoscopy" under Item, and "adenomatous polyp, repeat 2014" under Value. Is this really harder than going through the hassle of adding a spreadsheet to each chart?
Agreed Amazing Charts could do a much better job at tracking such data
