Risk factors and prognoses of invasive Candida infection in surgical critical ill patients with perforated peptic ulcer

The risk of invasive Candida infection (ICI) is high in patients with perforated peptic ulcer (PPU) who received laparotomy or laparoscopic surgery, but the risk factors and predictors of morbidity outcomes remain uncertain. This study aims to identify the risk factors of ICI in surgical critically ill PPU patients and to evaluate the impact on patient's outcomes. This is a single-center, retrospective study, with a total of 170 surgical critically ill PPU patients. Thirty-seven patients were ICI present and 133 were ICI absent subjects. The differences in pulmonary complications according to invasive candidiasis were determined by the Mann–Whitney U test. Evaluation of predictors contributing to ICI and 90-day mortality was conducted by using multivariate logistic regression analysis. Candida albicans was the primary pathogen of ICI (74.29%). The infected patients had higher incidence of bacteremia (p
