Their high cost may restrict use.</span></p><h4 style="font-size: 13px; margin: 0px 0.25em 0px 0px; text-transform: uppercase; float: left; font-family: arial, helvetica, clean, sans-serif;"><span style="font-size: 10pt;">AIMS:</span></h4><p style="margin: 0px 0px 0.5em; line-height: 1.538em; font-size: 1.04em; font-family: arial, helvetica, clean, sans-serif;"><span style="font-size: 10pt;">This pilot study investigated the efficacy and compared the costs of routine universal use of peracetic acid sporicidal wipes versus sporicidal quaternary ammonium compound and alcohol wipes in the disinfection of a hospital environment.</span></p><h4 style="font-size: 13px; margin: 0px 0.25em 0px 0px; text-transform: uppercase; float: left; font-family: arial, helvetica, clean, sans-serif;"><span style="font-size: 10pt;">METHODS:</span></h4><p style="margin: 0px 0px 0.5em; line-height: 1.538em; font-size: 1.04em; font-family: arial, helvetica, clean, sans-serif;"><span style="font-size: 10pt;">The routine universal use of peracetic acid wipes (Clinell Sporicidal; GAMA Healthcare Ltd, London, UK) was allocated to a study ward, whereas the control ward continued with the use of quaternary ammonium compound wipes (Tuffie 5; Vernacare, Bolton, UK) and alcohol wipes (PDI Sani-Cloth 70; PDI, Flint, UK). Twenty high-touch areas in the 2 wards were sampled for the presence of indicator organisms. The weekly detection rates of indicator organisms and weekly healthcare associated infection (HCAI) rates in the 2 wards were compared and examined for decreasing trends over the trial period.</span></p><h4 style="font-size: 13px; margin: 0px 0.25em 0px 0px; text-transform: uppercase; float: left; font-family: arial, helvetica, clean, sans-serif;"><span style="font-size: 10pt;">RESULTS:</span></h4><p style="margin: 0px 0px 0.5em; line-height: 1.538em; font-size: 1.04em; font-family: arial, helvetica, clean, sans-serif;"><span style="font-size: 10pt;">The detection rates of indicator organisms and HCAI rates were not significantly different in the 2 wards, and did not decrease significantly over the trial period. However, the peracetic acid wipes seem to be more effective against gram-negative organisms but at a significantly higher cost.</span></p><h4 style="font-size: 13px; margin: 0px 0.25em 0px 0px; text-transform: uppercase; float: left; font-family: arial, helvetica, clean, sans-serif;"><span style="font-size: 10pt;">CONCLUSIONS:</span></h4><p style="margin: 0px 0px 0.5em; line-height: 1.538em; font-size: 1.04em; font-family: arial, helvetica, clean, sans-serif;"><span style="font-size: 10pt;">Further prospective studies are needed to assess the cost-effectiveness of peracetic acid wipes.</span></p>
