A comparative study of risk factors and outcome among outpatient-acquired and nosocomial candidaemia.
Candidaemia is perceived as a nosocomial infection. The aim of this study was to describe all cases of candidaemia that occurred in the outpatient setting, and to compare risk factors and outcome among patients with outpatient-acquired and nosocomial candidaemia. During 1995 and 2003, 210 patients developed candidaemia at our institution, and 9.0% were outpatient acquired. Major underlying diseases were cancer (47.4%) and chronic renal failure (36.8%). Most occurred within 24 h of hospitalization (63.2%), and 83.7% were caused by species other than Candida albicans, mainly Candida parapsilosis (36.8%). Candida spp. were isolated from catheters in 21% of cases, and 52.6% of patients had been admitted to hospital in the 60 days preceding candidaemia. Compared with patients with nosocomial candidaemia, chronic renal failure was more frequent in the outpatient group, who were also more commonly exposed to haemodialysis. Ileus, gastrointestinal bleeding, previous bacteraemia, use of proton pump inhibitors, previous stay in the intensive care unit and requirement for antibiotics, blood transfusion, vasopressors and invasive medical procedures were more frequent in the nosocomial group. Overall mortality was high in both groups. Candidaemia must be considered as a potential cause of sepsis in the community, and it is associated with a high mortality rate.
