Control (SENIC) to determine whether infection surveillance and control programs have reduced the rates of nosocomial (hospital-acquired) infection in US hospitals. This data set consists of a random sample of n=113 hospitals selected from the original N=338 hospitals surveyed. Each hospital is given an ID number, and is measured on 11 other variables.
