Impact of Candidemia on Survival Rates in Major Burn Patients: A Retrospective Study from the South of Türkiye

Abstract

Objective In severely burned patients, fungal infections are among the most devastating complications. Candidemia is an important cause of mortality with an increasing incidence despite advances in burn care management. Higher affected body surface area, long intensive care unit (ICU) stay, flame burn, third-degree burn, and previous bacterial infections were associated with the development of candidemia. Candidemia in patients with major burns admitted to an ICU of a tertiary burns center is investigated.

Methods Patients hospitalized in the ICU of Adana City Training and Research Hospital from July 1, 2017, to November 10, 2020, were included. The demographic and clinical variables, the Candida species isolated from blood cultures and their antifungal susceptibilities, need for grafting, complications, and rate of mortality are evaluated retrospectively. Patients were grouped as “candidemia” or “noncandidemia” according to whether or not they experienced Candida bloodstream infection.

Results A total of 371 patients were included; the mean age was 22.02 ± 20.9 years. Most patients were male (69.5%). The percentage of burned surface area was 25.93 ± 17.6. The mean ICU stay was 16.95 ± 16.3 days. There were 90 candidemia episodes in 69 patients. The most commonly isolated Candida species were C. parapsilosis, C. tropicalis, and C. albicans. The mortality rates in the candidemia and noncandidemia groups were 24.6 and 5.6%, respectively (p < 0.001).

Conclusion Adhering to isolation rules, early wound debridement and closure, avoidance of catheters where possible, and avoidance of the early use of broad-spectrum antibiotics are important measures in reducing candidemia in patients with major burns. Candidemia was associated with greater burn surface areas, duration of hospital stay, and larger numbers of interventional procedures. However, previous bacterial infection receiving prolonged antibiotic therapy was the greatest risk factor of candidemia. Culture results are important to select the antifungal agent with high susceptibility, but results are not rapidly available. There is need for early clinical prediction measures to inform early and effective antifungal treatment.
