An outbreak of Candida spp. bloodstream infection in a tertiary care center in Bogotá, Colombia.

Several cases of Candida bloodstream infections were documented from June to October 2004 at a tertiary care center in Bogotá, Colombia. Since no cases of candidemia had occurred during the preceding four months, an outbreak was declared. As a result, a microbiological study, a revision of infection control practices and a case-control study were performed. In all, 18 cases of candidemia were ascertained. Parenteral nutrition (p=0.04), presence of a central line (p=0.03), and severity of illness (p=0.03) were associated with candidemia in bivariate analysis. Diverse Candida species were observed. Candida parapsilosis contamination was found in plastic containers used for transient intravenous (IV) medication storage at the bedside, plastic bags reused for the transportation of IV medicines and cotton used for disinfection of IV ports. Poor infection control practices were widely observed. The outbreak was controlled after elimination of plastic bags used for transportation, instauration of daily disinfection of IV medication containers, acquisition of sterile alcohol swabs for port disinfection and staff education. It was concluded that candidemia was associated with previously-described risk factors and that poor infection-control practices were likely responsible for the outbreak.
