The Recall Reasons screen (File > Setup > Recalll Reasons) allows you to add the reason and the default number of months between the last exam date and the next recall date for the patient. You can also setup a recall schedule for each recall reason which would define a recall or follow up letter to be sent to the patient a certain time before or after the recall date. Recall reasons defined here are available in the ‘Profile’ tab of the Patient module and the ‘Assessment’ tab of the Exam module.
