Developing Event. Level Estimates The data in this file can be used to develop national 2007 event level estimates for the U.S. civilian noninstitutionalized population on inpatient hospital stays as well as expenditures, and sources of payment for these stays. Estimates of total stays are the sum of the weight variable (PERWT07F) across relevant event records while estimates of other variables must be weighted by PERWT07F to be nationally representative. The tables below contain event-level estimates for selected variables.
