Trial Outcomes & Findings for Preventing the Spread of Infection in Nursing Homes (NCT NCT03319368)

NCT ID: NCT03319368

Last Updated: 2024-03-21

Results Overview

Rates of Staphylococcus aureus acquisition in the baseline and intervention periods: Participants were swabbed in the anterior nares and inguinal fold at nursing home admission (or start of study period) and again at discharge (or end of study period). This is the percentage of participants who acquired MRSA or MSSA (or both) during the study period.

Participant Flow

Long stay residents (n=42) were enrolled in the study specifically to examine if they transmitted S. aureus to short stay residents for the secondary outcome measure. They were excluded from all other study analyses.

PRIMARY outcome

Timeframe: 5 months: 2 months in the baseline period, one month to prep the intervention, then 2 months in the intervention period

Population: All short stay participants who had admission and discharge swabs collected and who were not co-colonized with MRSA and MSSA on admission swabs.

Rates of Staphylococcus aureus acquisition in the baseline and intervention periods: Participants were swabbed in the anterior nares and inguinal fold at nursing home admission (or start of study period) and again at discharge (or end of study period). This is the percentage of participants who acquired MRSA or MSSA (or both) during the study period.

SECONDARY outcome

Timeframe: 5 months

Population: All short stay participants who had admission and discharge swabs collected and who were not co-colonized with MRSA and MSSA on admission swabs.

Rates of Staphylococcus aureus transmission in the baseline and intervention periods: Participants were swabbed in the anterior nares and inguinal fold at nursing home admission (or start of study period) and again at discharge (or end of study period). The DNA sequences of each SA isolate from each acquisition were evaluated to see if there was a match to another epidemiologically linked (same floor, same study period) SA isolate. This is the percentage of participants who acquired MRSA or MSSA (or both) from MRSA/MSSA transmission from another study participant during the study period.
