Hand hygiene and instrument sanitization in ophthalmology clinics.

ABSTRACT

PURPOSE OF REVIEW This article reviews the various challenges in infection control in eye clinics and successful measures taken to prevent nosocomial infections. RECENT FINDINGS: The Center for Disease Control recommends hand-washing when hands are visibly soiled, and after direct contact with patients, and inanimate objects such as medical equipment. Published studies have identified poor hygiene in clinical settings as a major cause of nosocomial outbreaks, particularly in cases of epidemic keratoconjunctivitis (EKC). Some studies of EKC outbreaks are able to support direct observation of hygiene lapses with molecular analysis that can match viral strains on particular instruments to those found in infected patients. Although most studies are about adenoviral infection and tonometer use, researchers have found viral and bacterial loads on other common surfaces, indicating a need for further research. SUMMARY: Proper hygiene in eye clinics requires special attention because of the potential to examine many patients at a time and because multiple instruments are often used during a single exam. Studies reinforce the link between hygiene and outbreak prevention, and more research can be done to determine the specific links between certain instruments and nosocomial infections.
