Effectiveness of a shielded ultraviolet C air disinfection system in an inpatient pharmacy of a tertiary care children's hospital

摘要

Viable air particles pose a risk in areas where sterile preparations are compounded. This study investigated the efficacy of an innovative air purification technology that uses a shielded ultraviolet C light lamp to continuously purify the air in an inpatient pharmacy. Mean airborne fungal and bacterial colony forming units were obtained preinstallation and again in 6 months. A statistically significant decrease of 78% and 62% was observed for fungal and bacterial particles, respectively. This study demonstrates a potential role for this novel technology in decreasing the spread of airborne pathogens.
