5 DESCRIPTION: THIS EXAMPLE SHOWS THE DIFFERENCE BETWEEN TWO USES OF
6 THE TERM "PRIORITY CONDITION" IN MEPS.
7
8 THE MEPS SUPPLEMENTAL PRIORITY CONDITIONS (PC) SECTION
9 ASKS (IN ROUNDS 2/4), FOR EACH PERSON, ABOUT THE
10 EXISTENCE OF CERTAIN PRIORITY CONDITIONS (SEE PAGES C-56 -
11 C-60 OF THE HC-097 DOCUMENTATION FILE).
12 INFORMATION COLLECTED IN THE PC SECTION OF THE MEPS
13 IS DISTINCT FROM THAT INCLUDED IN THE CONDITION
14 ROSTER. THESE CONDITIONS ARE NOT PART OF THE CONDITION
15 ROSTER UNLESS THEY ARE MENTIONED ELSEWHERE IN THE
16 INTERVIEW. NOTE THAT PC QUESTIONS ARE OF THE FORM,
17 "HAS PERSON *EVER* BEEN TOLD BY A DOCTOR OR OTHER
18 HEALTH PROFESSIONAL THAT THEY HAVE (CONDITION)?"
19 THE VARIABLES ASSOCIATED WITH THESE PC SECTION
20 QUESTIONS ARE ON THE FULL-YEAR FILE (HC-097 FOR 2005).
21
22 THE CONDITIONS FILE ALSO HAS A SET OF CONDITIONS
23 FLAGGED AS PRIORITY BY THE VARIABLE PRIOLIST (SEE APPENDIX
24 4 OF THE CONDITIONS FILE DOCUMENTATION). THESE
25 CONDITIONS MIGHT COME FROM A REPORT OF BEING BOTHERED BY THE
26 CONDITION DURING THE YEAR, FROM AN ASSOCIATED
27 EVENT OR PRESCRIPTION MEDICINE IN THE YEAR, FROM BEING
28 ASSOCIATED WITH A DISABILITY DAY DURING THE YEAR, OR AS A
29 FOLLOW-UP QUESTION FOR A PREVIOUSLY REPORTED CONDITION WHERE
30 THE PRIORITY LIST FLAG IS SET (PRIOLIST=1). SETTING THE
31 PRIORITY LIST FLAG IS A MANUAL PROCESS AND MAY NOT HAVE BEEN
32 SET FOR ALL ELIGIBLE CONDITIONS.
