Scrubs contamination, domestic laundry effect and workwear habits of clinical staff at a referral hospital.

OBJECTIVE

To determine contamination rates of scrub suits worn by veterinary surgeons and nurses following a single shift.

MATERIALS AND METHODS

Cross-sectional preliminary study at a UK small animal referral centre. Sterilised scrub suits were distributed to veterinary surgeons (n = 9) and nurses (n = 9) at the beginning of their clinical shift and worn for at least 8 hours. They were then analysed for bacterial contamination before and after home laundry at 30°C. A questionnaire was distributed to hospital clinical staff regarding workwear habits.

RESULTS

Median bacterial counts were 47 (interquartile range: 14 to 162) and 7 (interquartile range: 0 to 27) colony forming units per cm before and after laundering scrub suits. Bacteria identified included Staphylococcus sp., Enterococcus sp., Escherichia coli , Bacillus sp., Pseudomonas aeruginosa , Micrococcus sp., β-haemolytic Streptococci and a Group G Streptococcus. From 101 staff surveyed, 64.0% reported wearing fresh, clean scrub tops and 58.4% fresh, clean trousers each day, while 64.4% left the workplace wearing the same clothing in which they undertook clinical work.

CLINICAL SIGNIFICANCE

Workwear contamination risks spread of pathogens into the community and personnel compliance with workplace guidelines warrants further attention. Home laundry at 30°C significantly decreases, but does not eliminate, the bacterial burden after a single shift.
