Trial Outcomes & Findings for Enhanced Room Cleaning in Intensive Care Units to Reduce Gown and Glove Contamination With Multi-drug-resistant Bacteria (NCT NCT01481935)

NCT ID: NCT01481935

Last Updated: 2022-02-16

Results Overview

Swabs will be collected from the disposable gown and gloves of healthcare workers exiting the enrolled room. A single swab will be used for both gloves and the gown. The swab will be assayed for methicillin-resistant Staphylococcus aureus, multi-drug-resistant Acinetobacter baumannii, or both, depending on which organism(s) the occupant of the enrolled room is colonized with. The swab will be considered positive if the relevant organism is isolated. We will sample the first 15 healthcare worker exits after the room has received the allocated intervention.

Measure
Sham Enhanced Cleaning
Rooms in the Sham Enhanced Cleaning arm received a single sham extra cleaning of frequently contaminated surfaces by a study researcher in addition to standard room cleaning by hospital housekeeping staff. Sham Enhanced Cleaning was performed once per day of enrollment and follow-up. Seventeen surfaces identified by the CDC as being 'frequently touched and frequently contaminated' were cleaned as part of the experimental intervention. Cleaning was performed using standard hospital cleaning products (wipes soaked in a commercially-available quaternary ammonium solution).

PRIMARY outcome

Timeframe: As a healthcare worker exits the enrolled room (1 day)

Population: Unit of analysis was the ICU room. Results from multiple participants who occupied a single room over the course of the trial were summarized by room.

Swabs will be collected from the disposable gown and gloves of healthcare workers exiting the enrolled room. A single swab will be used for both gloves and the gown. The swab will be assayed for methicillin-resistant Staphylococcus aureus, multi-drug-resistant Acinetobacter baumannii, or both, depending on which organism(s) the occupant of the enrolled room is colonized with. The swab will be considered positive if the relevant organism is isolated. We will sample the first 15 healthcare worker exits after the room has received the allocated intervention.
