Bacterial colonisation and the effect of a cleaning regime on iPad patient side electronic devices used in a veterinary healthcare setting.

Abstract

OBJECTIVES: This study aimed to determine the prevalence of clinically relevant bacteria on the surface of hospital-issued iPads and to assess the effectiveness and residual effect of a new cleaning regime using 70% alcohol and 2% chlorhexidine wipes. METHODS: Hospital-issued iPads were swabbed to determine the presence of clinically relevant organisms. The iPads were wiped using 70% alcohol and 2% chlorhexidine. Further samples were taken 5 mins, 6 h and 12 h after implementation of the cleaning regime. Cultured bacteria were tested for antimicrobial resistance. RESULTS: A total of 25 hospital-issued iPads were analysed. Seventeen iPads (68%) sampled in this study were contaminated.species (21%) were the most predominant, followed byspecies (14%),species (11%),species (11%), beta-haemolytic streptococci (11%), coagulase-positive staphylococci (7%),(7%), coagulase-negative staphylococci (7%), alpha-haemolytic streptococci (3%),species (4%) andspecies (4%). Of the isolated bacteria, 89% were resistant to at least one of the tested antibiotics. Of our isolates, 24 (75%) were resistant to clindamycin. After the cleaning regime, there was no bacterial growth from any of the devices at 5 mins, 6 h and 12 h despite repetitive use within the hospital. CONCLUSIONS AND RELEVANCE: A variety of nosocomial pathogens, including antibiotic resistant pathogens, were isolated from the iPads. Cleaning with 70% alcohol and 2% chlorhexidine wipes is recommended every 12 h during use, between patient contacts and after witnessed contamination. A variety of nosocomial pathogens, including antibiotic-resistant pathogens with potential devastating effects on both human and animal health, were isolated from the iPads. Infection prevention strategies related to the devices should be employed in a hospital setting.
