Burden of aspergillosis-related hospitalizations in the United States.

In the United States in 1996, there were an estimated 10,190 aspergillosis-related hospitalizations (95% confidence interval [CI], 9000-11,380); these resulted in 1970 deaths (95% CI, 1659-2280), 176,272 hospital days (95% CI, 147,163-206,275), and $633.1 million in costs (95% CI, $492.0-$780.2 million). The average hospitalization lasted 17.3 days (95% CI, 16.1-18.6) and cost $62,426 (95% CI, $52,670-$72,181). Although aspergillosis-related hospitalizations account for a small percentage of hospitalizations in the United States, patients hospitalized with the condition have lengthy hospital stays and high mortality rates.
