I don't know if it will improve performance but since you know that in a = certain number of cases you will get a SQL%NOTFOUND why not use IF/THEN = to deal with it instead of throwing an exception?

select title, volume, pages, year, journalid

into ttl, vol, pg, yr, jid from ref where id=3Drn; begin

       select abbrev into jname from journal2abbrev
       where id=3Djid and medline=3D'Y';
	IF SQL%NOTFOUND THEN
      select name into jname from journal where id=3Djid;
	END IF;
     end;
