Characteristics and Outcomes of Long-Stay Patients in the Pediatric Intensive Care Unit

Long-stay patients in the PICU have a higher risk of mortality as compared with non-long-stay patients. We aim to describe mortality and characteristics of long-stay patients and to determine the risk factors for mortality in these children. Total 241 (4.8%) long-stay admissions were identified. Mortality of long-stayers was 48/241 (20%). Higher severity-of-illness score at admission, need for organ support therapies, number of nosocomial infections, and bloodstream nosocomial infection were associated with a higher mortality in long-stay patients in the PICU. Based on multivariate analysis, oncologic diagnosis as a preexisting comorbidity is a strong independent predictor of mortality for long-stay patients.
