• | How to implement an ultraviolet (UV) disinfection program efficiently to reduce nosocomial disease rates in acute care settings is not well understood. |
• | Using 2 robots, we achieved 6-month disinfection averages of approximately 87%. Using a dedicated UV technician team, timing shifts during high discharge periods, and setting isolation rooms per shift goals improved coverage. |
• | Rooms were not held for the purpose of UV disinfection. |

Résumé |
Background |
Ultraviolet (UV) disinfection decreases nosocomial disease rates in acute care settings; effective program implementation is poorly understood. We developed a program to UV-disinfect rooms following discharge of patients in transmission-based precautions (TBP) and assessed its effect on hospital-acquired infection (HAI) rates.
Methods |
An isolation room housed a patient in any type of TBP. A priority room was an isolation room in TBP for multidrug resistant organisms or Clostridioides difficile infection. Percent rooms disinfected and HAI rates were calculated monthly. The two-robot program was started by Infection Prevention utilizing a single environmental services employee. Efficiency was increased by granting environmental services’ personnel oversight, increasing coverage, and modifying shift-based goals. Our primary goal was disinfection of all discharged priority rooms. Our secondary goal was disinfection of all discharged isolation rooms.
Results |
The program achieved 6-month disinfection averages of 85.7% of isolation, and 87.7% priority rooms, respectively. Using a dedicated UV disinfection team and setting isolation room per shift goals improved coverage. HAI rates decreased by 16.2% following program implementation.
Conclusions |
We implemented an effective UV disinfection program, and observed HAI reduction, by focusing on broad coverage and efficient deployment of assets without affecting patient flow or expanding the robot fleet.
