The dirty truth of hospital cleaning: thin science
Modern Healthcare

U.S. hospitals are evaluated on their ability to reduce the incidence of infections patients acquire during their stays, but there’s surprisingly little evidence suggesting the best method to disinfect surfaces in patient rooms.

An abundance of research looks at the number of bacteria on a surface before and after cleaning and disinfecting. But few studies have taken the next step to specifically evaluate to what degree those procedures led to fewer patients getting sick. Even fewer studies compared the effectiveness of one environmental cleaning method over another, according to an analysis published Aug. 10 in the Annals of Internal Medicine.
