[Nosocomial infections. State of the art]. / Le infezioni nosocomiali. Stato dell'arte.

ABSTRACT

Little information exists up till now about the prevalence of nosocomial and community acquired infections in Italian hospitals. Little is known about the effects of thorough cleaning in today's hospitals. This review examines the common microorganisms associated with hospital acquired infections and their ability to survive in the hospital environment. The most frequent site of hospital acquired infections is the urinary tract, followed by surgical wounds and the upper respiratory tract. Analysis of North America and European data shows that the increase in length of stay for infected patients is the most striking of all examined costs. Improving standards of hygiene in hospitals would be a safe method to control hospital-acquired infections and their costs.
