title: Nosocomial infections on nursing units with floors cleaned with a disinfectant compared with detergent.
abstract: Nosocomial infections on eight acute care nursing units in a tertiary care hospital was compared between two 3-month periods in which floors were cleaned with either disinfectant or detergent. Personnel performing infection surveillance were unaware of the cleaning product used. Surface cultures from selected floor sites were obtained at 3 and 6 months to assess microbial contamination. The combined nosocomial infection rate for the eight wards did not differ between disinfectant (8.0/100 patient discharges) and detergent (7.1/100). For individual wards, a significant difference in nosocomial infection rate between the two periods was observed in only one ward, favouring the detergent. No differences in floor contamination were observed.
