General Notes
 

Admission day of the week (ADAYWK) is calculated from the admission date (ADATE). If ADAYWK cannot be calculated (ADATE is missing or invalid), then:

  • ADAYWK is set to the supplied admission day of the week, if available.
  • ADAYWK is missing (.) if the supplied admission day of week is missing.
  • If ADAYWK is out of range (ADAYWK NE 1-7) or nonnumeric, it is set to invalid (.A).
  • In the 1988-1997 HCUP files, if the data source does not provide the admission date or admission day of week, then ADAYWK is set to unavailable from source (.B).

Beginning in the 1998 HCUP files, the data element ADAYWK is replaced by admission weekend (AWEEKEND).

State Specific Notes

Maryland

For 1990-1994, the source did not report admission day of week. Only the calculated admission day of week could be used to assign ADAYWK.

Beginning in 1995, the source reported admission day of week. During HCUP processing, ADAYWK was assigned using the reported admission day of week if the day could not be calculated from admission date.



New York

In the 1988-1997 HCUP New York databases, ADAYWK could not be calculated because New York did not report full admission dates. During HCUP processing, only the reported admission day of the week could be used to assign ADAYWK. Please refer to the notes for AWEEKEND for information on this data element in data years after 1998.
