In response to the question on how to identify Nosocomial Pneumonia patients, there were different ways suggested to determine or validate on which some questions below
1. Patricia suggested “ Examine the DRG code for the patient-is it pneumonia or something else? Is pneumonia primary or secondary? If the DRG is for something else, the pneumonia is nosocomial.”
a. Is DRG code identified by the variable “RXNAME” (If am right, “RXNDC” is the
corresponding code for each RXNAME) in the medication file? If so, how do we
identify from the name which is for Pneumonia versus not?
2. There are 384 patients with one or more of the diagnosis suggesting Pneumonia of which 257 patients have SPECCOND = 1 (meaning Pneumonia is due to the hospital stay) and remaining 124 patients have missing SPECCOND. Does this mean these 257 patients are nosocomial Pneumonia patients and the rest are not?
