Jordan A. Kempker, MD, MSc August 4, 2016 NIS 2002-2011 Hospital-Level Variables This Code will create the below hospital-level variables for the entire dataset and then merge these statistics back into each observation. hosp_vol Number of Annual Hospital Discharges hospmort Annual Hospital In-Hospital Mortality Rate Average Annual Hospital Elixhauser Score Of note, this code was first tested on a random 5% sample stratified by year before applying to entire dataset. Below, is the pared down functional version that resulted but does not contain any of the internal tests.<br>Jordan A.
