Kumar,

Typically, the records are in one dataset with a screening date. Sort on patient ID and date and then use a datastep to keep only the last record per patient using the last.pid functionality.

Hi Y'all:

I am trying to do the following:

Patients come in for Screening and some of them are required to come in
for Repeat Screening. In the event the patient is required to come in
for a repeat screening, the screening values are to be "deleted" and the
Repeat Screening to be used as Screening.


At this point, I am at a loss as to how to go about doing this. Any
help would be greatly appreciated.

TIA

Kumar
