Introduction:

Infections Associated with Health Care (IAAS) are a serious problem for health care facilities, not only as a cause of morbidity and mortality but also because of the high costs they generate. Contaminated environments are a danger for any health care facilities.

Objective:

To determine the efficacy of hospital disinfectants against microorganisms isolated from surfaces (ventilator, monitor and surface of the hospital bed) in critical areas of the “Santa Rosa” Hospital, Lima-Peru.

Material and Methods:

An observational, prospective and cross-sectional study was conducted to evaluate disinfection products used to clean floors and surfaces. The surface challenge test was performed using control strains. Samples were collected from the adult intensive care unit (ICU), the neonatal intensive care unit (NICU) and the special care unit (SCU) of the Santa Rosa Hospital. The effect of the disinfectants was evaluated at the fifth, tenth and fifteen minutes.

Results:

Under the study conditions and considering the time and speed of bacterial death due to the disinfectant effect, the most effective products were quaternary ammonium (Supersafe-D) and 1% sodium hypochlorite.

Conclusions:

None of the disinfectants met the chamber test requirements. The products achieved the expected effects after 10 to 15 minutes.
