Finding a patient by name
To find a patient without having to scroll through your entire list of patients, start by going to the Patients tab. Above your list of patients, you will see a blue box that says "Add a filter". Click on it, and then click on "Last name". You will see a place to enter the last name of the patient for whom you are looking.
Enter the patient's last name in the appropriate field, and click "apply". Your screen will refresh to show you only those patients who have the last name you entered.
