 It is standard of care for ELBW infants in the Duke Intensive Care Nursery that non-sterile gloves are worn by all providers and family members for contact with the infant for the first two weeks of life. Providers and relatives will be asked to place used gloves in a zip-lock bag at the bedside after contact with the infant. The gloves will be grouped into zip-lock bags by provider type medical provider, nurse, or ancillary staff or relative. The bags will be collected each shift or day. Glove samples will not be labeled or linked with individual providers or relatives.
