I agree completely. Fortunately, at this time my PM program has a reminder feature. My staff can enter in a reminder and it will pop up at the desired date and time as soon as they sign on. For instance, if Joe Schmo needs a repeat CT of the chest in 6 months, I have the ladies enter it to have it pop-up in 5 months and 2 weeks so we can get it scheduled for them. You can also bring up all the reminders in the system at once in order to review them. Very nice feature.
I also use the "sticky note" feature of AC to make reminder notes such as when a patient's next colonoscopy is due but this will not appear unless you opent their chart.
