ObjectiveTo evaluate the prevalence of fungal infections (both pre-cannulation and post-cannulation) while on extracorporeal membrane oxygenation support and the associated morbidity and mortality.DesignRetrospective cohort study.Patient And MethodsThe Extracorporeal Life Support Organization database is an international voluntary registry of clinical data for patients placed on extracorporeal membrane oxygenation. The database was queried for all patients on extracorporeal membrane oxygenation from 1997 to 2009. Patient and extracorporeal membrane oxygenation data collected included age, support type, length of support, infection status and organism code, discharge status, complications, and component failures. Outcomes of interest were mortality, extracorporeal membrane oxygenation-related patient complications, and mechanical component failures.ResultsFrom 1997 to 2009, there were 21,073 patients' extracorporeal membrane oxygenation runs analyzed of which 12,933 were in the neonatal group (0-30 days), 6,073 were in the pediatric group (31 days to <18 yrs old), and 2,067 were in the adult group (≥18 yrs). The prevalence of fungal infection during extracorporeal membrane oxygenation varied by age group and timing of infection and ranged from 0.04% to 5%. Fungal infections pre-extracorporeal membrane oxygenation and on-extracorporeal membrane oxygenation conferred a statistically significant higher relative risk of mortality for all age groups and varied by support type and timing of infection. Extracorporeal membrane oxygenation-related complications and component failures were not statistically significantly affected by infection status.ConclusionsFungal infection before or during extracorporeal membrane oxygenation increases the odds of mortality and the magnitude of this effect is dependent upon age-group and timing of infection. This increased mortality was not the result of increased patient or mechanical complications during extracorporeal membrane oxygenation. For patients with fungal infections pre-extracorporeal membrane oxygenation, 82%-89% demonstrated presumed clearance during extracorporeal membrane oxygenation. Although the risk of mortality increased with fungal infections, it does not appear that fungal infection before or during extracorporeal membrane oxygenation is a contraindication to initiation or continuation of support.
