Sixty episodes of candidemia occurring between January 1987 and September 1989 were retrospectively reviewed and the outcome was compared for three patient categories: neutropenic, postsurgical, and nonneutropenic nonsurgical. Because of increasing reports of resistant yeasts, minimal inhibitory concentrations (MICs) to amphotericin B (amB) were determined to examine its relationship to patient outcome. No significant differences between patient categories were found for selected risk factors, mortality, or species isolated, although there was a tendency for Candida tropicalis to occur in neutropenic patients. Statistical analysis using logistic regression showed that both an amB dose greater than 500 mg and a yeast MIC greater than 0.78 micrograms/ml were independent prognosticators of patient outcome.
