The Most Effective Part of Infection Control to Reduce the Incidence

The most effective part of infection control to reduce the incidence of health care-associated infections (HAIs) is to:

A) use surgical asepsis for care of patients outside the operating room who are most at risk for a HAI.
B) put all patients with wounds or invasive procedures on transmission-based precautions before they become infected.
C) place an alcohol-based hand sanitizer solution in every patient room.
D) use proper hand hygiene before and after caring for any patient, before donning gloves and after their removal.
