How to combine OR , AND in one filter formula in google sheet

=filter('CASES LIST'!C:S,'CASES LIST'!Q:Q="admission",len('CASES LIST'!S:S))

I have in the sheet column Q - has "admission", "consultation", other items in dropdown list.

In column S- other dropdown list as well.

In column R- drop down list

I want to filter data based on either of these two criteria:

1- Column Q="admission" AND column S is not empty

2- OR Column Q= "consultation"

If either of these criteria is met, the row C:S, will be copied to the desired sheet

I made this formula, but it doesn't seem working

=filter('CASES LIST'!C:S,'CASES LIST'!Q:Q="admission",len('CASES LIST'!S:S))+('CASES LIST'!Q:Q="consultation")
