Hi @Abhishek_24

Assuming you’re looking to filter for rows where the patient had a visit after X days, you could:

  1. Calculate difference in days from the previous visit for each patient (refer: Lag - Amazon QuickSight and dateDiff - Amazon QuickSight

  2. Apply filter on the diff in days calculated in step 1 and calculate distinct count of patient ids

Quick prototype to illustrate:

In QuickSight after adding the calculation:

Applying filter on days diff to find out visits after 40 days:
