Conditions
Summary
RESPROTECT is a trial aimed at evaluating the effectiveness of upper room ultraviolet devices in reducing the frequency of severe respiratory infections in elderly nursing homes. The study takes place in 12 nursing homes in the center of France. It started in October 2024, and its final results will be availble by mid-2026.
Eligibility
Inclusion Criteria7
- Elderly Nursing homes (ENH):
- Having a system for monitoring cases of upper and lower respiratory infections among their residents.
- Agreeing to take part in the study
- Undertaking to comply with the protocol
- Accepting the installation of UVGI devices
- Undertaking to provide all residents or their legal guardians/curators with an individual information leaflet.
- All residents present in one of the participating ENH at the start of each of the two study periods, or arriving in one of the participating ENH during one of the two periods, will be eligible
Exclusion Criteria4
- ENH:
- Not wishing to be equipped with UVGI devices in all rooms considered necessary to be equipped by the investigators
- Having planned a major change to the structure (extension, renovation, closure, requalification, etc.) during the course of the study, which could affect the study population and/or UVGI air treatment devices.
- Residents of the ENH included in the study who have expressed (personally or through a relative or legal representative) the wish that their personal data not be used for the study will not be included in the study.

Interventions
Nursing homes are equipped with UVGI devices in all common living places. UVGI devices can be deactivated by installing an invisible internal filter. The inactivation filters will be installed by a technical team independent of the investigation team. Inactivation will therefore be carried out blind to the care givers and the investigation team. The centers included will be randomized into two arms. In arm A: the UVGI device will be left active during period 1, and filtered/deactivated during period 2. In arm B: the UVGI device will be filtered/deactivated during period 1 and left active during period 2. The two periods will last 7 months each, and will take place two years in a row on the same dates (October 1 to April 30). They will be separated by a 5-month wash-out period (May 1 to September 30), during which all UVGI equipments will be switched off in both arms.
