Can't find your patient's clinical note?
The most likely culprit is the associated appointment was deleted and therefore the clinical note attached to that appointment was deleted.
To verify that this was the cause follow these steps:
1. Go to Clinical > Audit Log
2. Search for the patient name. Make sure that the date range is correct
3. If the appointment was deleted there will be a log of the deleted appointment
4. Now that you have this information, you can go in and recover the appointment. Learn how to here!
