data, AHRQ developed new discharge trend weights for the 1993-2011 NIS. These weights were calculated in the same way as the weights for the redesigned 2012 NIS, and are designed to be used instead of the original NIS discharge weights for trends analysis. For trends analysis using NIS data 2011 and earlier, revised weights should be used to make estimates comparable to the new design beginning with 2012 data.
