Attributable mortality of nosocomial candidemia, revisited.

We reexamined the attributable mortality of nosocomial candidemia 15 years after a retrospective cohort study performed at our hospital demonstrated an attributable mortality of 38%. For all episodes of nosocomial candidemia between 1 July 1997 and 30 June 2001, we matched control patients with case patients by age, sex, date of hospital admission, underlying disease(s), length of time at risk, and surgical procedure(s). We analyzed 108 matched pairs.
