What do you like best?
We like PDFfiller because our patients don't want to have to waste precious minutes of their appointment time completing a health history update in the office. It's much simpler, not to mention faster, to have them do it at home and submit it when they're done!
What do you dislike?
The log-in process for the patient who has never used this service. We have a few patients who value their privacy and would rather not have to create an account in order to complete a form.
What problems are you solving with the product? What benefits have you realized?
PDFfiller is wonderful for our new patients! We send them to our website and have them navigate to where we have the clickable button to either complete the forms online or to print and bring them with to their appointment.
