Follow up is referring to a patient that needs to come back to a practitioner for the same condition for further treatment or to check the patient progress.  The follow-up indication will assist the practitioner to draw a report to indicate all the patients that need a follow-up consultation which is booked for a follow-up consultation. The follow-up consultations normally will take less time from the practitioner as a patient that comes for the first time to the practitioner. This can be used to organise the practitioners time more efficient.
