Summary
In 12 Danish care homes (635 residents), homes with far-UVC lamps in common rooms had fewer hospital-treated infections and antibiotic prescriptions than homes with usual care. Homes with lamps in residents' rooms as well showed no clear change. The trial was not randomised, and its authors call the results preliminary.

- Lamps in common and residents' rooms: infection rate ratio 0.69 (95% CI 0.23 to 2.07), not a clear change.
