Study: Cleaning Protocol Has Limited Effect on Multidrug-Resistant Bacteria

Current cleaning protocol may be insufficient to eliminate multidrug-resistant Acinetobacter baumannii in patient rooms, according to a study in the American Journal of Infection Control.

Researchers studied cultures from 32 hospital rooms from which patients with a known history of MDR A. baumannii were recently discharged. Fifteen rooms (46.9 percent) tested positive for MDR A. baumannii before terminal cleaning of the room. After cleaning, eight rooms — 25 percent — remained positive for the bacteria.

Of the 12 sites in the rooms that tested positive after cleaning, 12.5 percent were the floor, 10 percent were the call button, 9.4 percent were the door handle, 7.4 percent were the bedside table and 3.8 percent were the supply cart.
