Question : COALESCE and AS with CASE WHEN statment, other ways?

Can't figure out if this is the only way to achieve wanted result. Probably not...i hope, but im stuck.
In a data retrival stored procedure i provide an integer that determines if some information should be hidden in query. A user might have the right to see scheduled item but not the information is scheduled for.

The information is an COALESCE as it has various of information to show due to joins. The only way I have come up with is the following:
     
     R.ResourceText+', '+
      COALESCE( CASE
                  WHEN ( RS.CreatedBy_SystemCompany_ID_FK = @syscompid
                         OR
                         RS.UpdatedBy_SystemCompany_ID_FK = @syscompid
                         OR
                         INV.CreatedBy_SystemCompany_ID_FK = @syscompid      
                         OR
                         PER.CreatedBy_SystemCompany_ID_FK = @syscompid      
                         OR
                         PRO.CreatedBy_SystemCompany_ID_FK = @syscompid
                      ) THEN null ELSE ' | INFORMATION UNAVAILABLE |'
                     
                END,
                FE.Feed_Title+' ('+FT.FeedType_Title+')',
                FE.Feed_Title,
                WO.WorkOrder_Title,
                EV.EventFlowOrder_Title,
                RS.ResourceSchedule_Title + ' | '+RS.ResourceSchedule_Description,
                RS.ResourceSchedule_Title,
                'not found' ) as RSTitle

Isn't there a smarter syntax or way? In above case I would have to use the CASE statement in all COALESCE's that needs information to be hidden.

Thanks in advance.

Answer : COALESCE and AS with CASE WHEN statment, other ways?

Yes that's what I meant.
In my opinion a function should increase performance however that's not always the case.
It's just a matter of trying.
