Randomized controlled trial evaluated efficacy of hydrogen peroxide and peracetic acid disinfection on clinician phones, suggesting routine practice impacts cleanliness.
We conducted a two-phase randomized controlled trial evaluating routine versus automated hydrogen peroxide-peracetic acid disinfection of inpatient clinician-assigned phones. Both strategies significantly reduced microbial bioburden and clinically important pathogens. High baseline contamination under routine practice suggests adherence, rather than intrinsic efficacy, is the primary determinant of device cleanliness.
