General Notes

An indicator of whether the admission day is on the weekend (AWEEKEND) is calculated from the admission date (ADATE). If AWEEKEND cannot be calculated (ADATE is missing or invalid), then AWEEKEND is missing (.) if ADATE is missing (.) or AWEEKEND is invalid (.A) if ADATE is invalid (.A). Beginning in the 1998 HCUP files, the data element ADAYWK is replaced by admission weekend (AWEEKEND).

State Specific Notes

Florida Prior to 2004, the procedure day was used to assign AWEEKEND because the data source does not provide information on the admission date. Beginning in 2004, the data source provided information on the admission date. Thus, AWEEKEND was calculated from the admission date (ADATE). Due to an error in HCUP processing, the values of AWEEKEND were incorrectly assigned in data year 2000. There is no way to determine AWEEKEND from other information on the discharge record. The original data element, reported procedure day of the week, is not retained on the HCUP record and the admission date is unavailable for discharges over 11 years of age. AWEEKEND is correctly coded in all other data years. Maryland During HCUP processing, AWEEKEND was assigned using the reported admission day of week if the day could not be calculated from admission date. New York In the 1998-2000 data, AWEEKEND was calculated from the admission date. Because New York masked the admission dates on AIDS/HIV* records, AWEEKEND is missing (.) on these discharges. *Beginning with 2005, New York identifies AIDS/HIV records by ICD-9-CM diagnosis code or DRG: An admitting, principal, or secondary diagnosis of "042" "043" "044" "7958" "27910", "27919", "2793", "1363", "79571", "07951", "07952", "07953", "V017" or "V08". A DRG of 488 through 490 or 700 through 716. *From 2001 - 2004 data, New York identifies AIDS/HIV records by ICD-9-CM diagnosis code or DRG: An admitting, principal, or secondary diagnosis of "042" "043" "044" "7958" "27910", "27919", "2793", "1363", "79571", "07951", "07952", "07953" or "V08". A DRG of 488 "HIV with Extensive Operating Room Procedure", 489 "HIV with Major related condition", or 490 "HIV with or without Other Related Condition". Please note that the admitting diagnosis is not retained in the HCUP databases.
