Staphylococcal bacterial contamination of portable electronic devices in a large veterinary hospital

Background Portable electronic devices are used regularly within the veterinary and medical environments. Use of these in clinical areas may predispose them to bacterial contamination and they could act as fomites, transmitting infection between clinicians and patients. Aim To determine the prevalence, origin and nature of Staphylococcal bacterial contamination on the surface of portable electronic devices used in a large small animal hospital. Materials and Methods Staff were surveyed on the frequency of portable electronic device use and device‐cleaning routines. Portable electronic devices were swabbed for staphylococcus species. Cultured cocci were tested for antimicrobial resistance and identified at the species level to help determine the likely source (human or animal). Findings Forty one of 48 (85%) of staff used a portable electronic device every day within the hospital. Useable swabs were obtained from 47 portable electronic devices. Staphylococci were found on 68% of portable electronic devices. Vancomycin and Oxacillin resistance were seen in 17 of 46 (37%) and 1 of 46 (2%) isolated colonies respectively, including four vancomycin resistant, coagulase‐positive staphylococci. 44% of staff never cleaned their device. Clinical Significance Portable electronic devices are commonly used in veterinary hospitals, but few staff routinely disinfect them. The use of disinfectant to reduce colony counts should be implemented when forming protocols for these devices in the hospital. The majority of staphylococci found were of likely human origin. It is suggested that contamination is therefore more likely to be originating from staff rather than patients.
