2. During ultraviolet disinfection, hospital-acquired CDI was 22 percent less than the year before pre-ultraviolet disinfection.
 
3. There was a 70 percent decrease for the adult intensive care units where the percentage of room discharges with ultraviolet disinfection was greater.

4. During ultraviolet disinfection, community-acquired CDI increased by 18 percent, and length of stay of all CDI cases was lower.

5. No significant difference was found in days to hospital-acquired CDI cases in rooms with a prior CDI occupant.
