Performance of fungal blood cultures by using the Isolator collection system: is it cost-effective?

Abstract

Enhanced recovery of fungal isolates from blood by using the Isolator system has been reported previously. We examined bacterial and fungal blood cultures during a 14-month period to determine if this enhanced recovery required a separate fungal culture and to determine the differential utility between a fungal blood culture and a routine bacterial culture. During this period, 84 of 5,196 (1.6%) fungal blood cultures and 170 of 25,702 (0.6%) bacterial blood cultures were positive for yeast or filamentous fungi. Thirty-seven positive fungal cultures, simultaneously collected, had correspondingly positive bacterial cultures. An additional 15 positive fungal cultures yielded isolates that had either been previously recovered from a bacterial culture or were recovered from a bacterial culture collected within 48 h. Of the 32 unpaired fungal cultures remaining, 5 were Candida albicans whose unique isolation was believed to be the result of specimen sampling variance rather than any enhanced recovery characteristics of fungal culture methods. Examination of patient data relating to the 27 remaining isolates (24 patients episodes) showed that only five fungal blood cultures (0.096% of all collected) had any impact on patient therapy d...Continue Reading
