General Notes
 

DISCWT10 is the discharge-level weight on the 10% NIS Sample Core file. To produce national estimates, use DISCWT10 to weight discharges in the Core file to the discharges from all community hospitals located in the U.S.

  • From 2001 on, DISCWT10 should be used to create all national estimates, including total charge.
  • In the 2000 NIS, there are two discharge-level weights (DISCWT10 and DISCWTcharge10). DISCWT should be used to create national estimates for all analyses except those that involve total charge. DISCWTcharge10 should be used to create national estimates of total charge.
  • In the 1998-1999 NIS, DISCWT10 should be used to create all national estimates, including total charge.
  • Prior to 1998, the discharge weight was named D10CWT_U.

For detailed information about the development and use of discharge and hospital weights, see the year-specific report on the Design of the HCUP Nationwide Inpatient Sample.
