Inactive Cases/Date Last Modified

Hello All,

I am trying to create a hidden value for date last modified. If the patient does not show up to the clinic or the nurse does not visit the patient they are tagged as “defaulters”. I was hoping that if i had a hidden value that I would be able to use it in order to create a multi-event reminder to remind the nurse that they should follow-up with their patient.

Any thoughts on if this is the right logic? If so, how can I pull the date last modified into my form?

Best,

Hawa
