The current selection of 'Outpatient' is shown above, note the date picker is displayed, prompting the user to indicate which date to display scheduled patients/ encounters. The 'Search by' option is used to show patients irrespective of any encounters. Thus patients that have no encounters can be listed via this option.
See next step below.
Once the selections are as desired, tap the Patient List back button to query the database and display the desired patient list.
Note the user must select the 'Add Site'/' +' button to add their custom sites to the application before an encounter can be created. In the screen above 2 sites have been added by the user. Selecting the red 'delete' icon will delete the site from the list.
