ObjectivesPrevious research has documented the presence of microbes on healthcare personnel (HCP) attire. This study aimed to explore the bacterial contamination and predictors of Escherichia coli (E coli) growth, as well as, hygiene and handling practices of HCP attire that could influence growth of E coli.MethodsDescriptive, cross-sectional study was used in this study. Convenience sampling of the 188 HCP was recruited from a main comprehensive hospital in the northern part of Jordan. Three swab samples were collected from three different parts of lab coats used by each participant. The generalised mixed linear model was used for the categorical variables and to identify the predictors of E coli growth on HCP attire.ResultsEnterococcus faecalis was the most common species of bacteria found on lab coat. The HCP attire coming from the emergency department (ED) was highlighted with slightly higher contamination of E coli compared with other departments, such as critical care units. Factors associated with significant E coli growth on HCP attire were lab coat use over scrubs and borrowing of lab coats. The predictors of positive E coli growth were working in the ED, storing HCP attire in hospital lockers, believing the transmission of pathogens by HCP attire and carrying attire wrapped around arms.ImplicationsHygiene practices and policies, including a washing facility on the hospital premises, are a must to keep the lab coats clean.ConclusionHCP should be cautious about the method of use and storage of lab coats they wear.© 2021 John Wiley & Sons Ltd.
