OBJECTIVE: Single-use supplies stored in bedside supply carts with paper packaging cannot be wiped with disinfectants. We aimed to determine the prevalence of pathogens on these unused supplies.
DESIGN: Prospective study over 7 weeks in 2025.
SETTING: Two pediatric ICUs at a university affiliated children's hospital.
PATIENTS: The unit of analysis was the bedside supply cart from each discharged ICU patient.
INTERVENTIONS: One swab was used to swab three supply items contained in a single drawer in a room's bedside cart. Carts had two drawers sampled, each with a swab for bacterial culture and respiratory viral nucleic acid amplification testing (NAAT).
RESULTS: Paper-packaged supply items (n = 840) from 70 consecutive bedside carts were swabbed after patient discharge. All bacterial swabs had no growth of pathogen [0/140 (0%), 95% CI 0%, 2.3%)]. A non-pathogen was cultured from 8/140 (5.7%) swabs [7/70 (10.0%) carts], most with scant growth [7/8 (87.5%) only one colony]. Non-pathogens (common commensal skin and oral flora) included coagulase-negative staphylococci (n = 5), Actinomyces oris (n = 1), aerobic spore-forming Bacillus (n = 1), and viridans group streptococcus [non-anginosus] (n = 1). Of viral swabs, 3/140 (2.1%, 95% CI 0.5%, 6.4%) were NAAT positive (3/70 (4.3%) carts). Room isolation status, length of stay, and ICU were not associated with a positive bacterial or viral swab.
CONCLUSIONS: Bacterial pathogen detection on supplies, a necessary step in transmission, was extremely low. Viral NAAT detection on supplies was low and likely exaggerated the risk of fomite transmission, as whether there was viable virus at sufficient concentration to transmit infection is unknown.
