Due to "meaningful use" requirements, most EMR software have been forced to include a patient portal. The portal is used for patients to fill out forms and keep their information current. Since the office already has the portal, why not use the same portal in the office? Simply add a computer in the lobby corner and point your patients to it when they need to fill out paperwork. The data will automatically flow into the EMR and the office will get meaningful use credit for actually using the patient portal.
Using the patient portal frees up the medical check in kiosk and allows for the majority of patients to pass through without waiting for others to fill out paperwork.
