The C. difficile infection rate is calculated as a rate per 1,000 patient days.  The "total patient days" represents the sum of the number of days during which services were provided to all inpatients during the given time period.  The rate is calculated as follows:

Number of new hospital acquired cases of C. difficile in our facility divided by number of patient days (minus newborn days) X 1,000 = C. difficile rate per 1,000 patient days.
