The Pediatric Intensive Care Unit as a Critical Care Setting for Adults during the COVID-19 Pandemic: A Service Evaluation.

One strategy to expand critical care capacity during the coronavirus disease 2019 (COVID-19) pandemic within the United Kingdom has been to repurpose other clinical departments, including the pediatric intensive care unit (PICU) and pediatric multidisciplinary team, to accommodate critically unwell adult patients. While multiple PICUs have treated adult patients with COVID-19, there is an absence of data on the characteristics of patients transferred to pediatric care and their resulting outcomes in comparison to standard adult intensive care unit (AICU) provision. Data were collected for all adult COVID-19 intensive care admissions between March and May 2020, in three ICUs within a single center: PICU, AICU, and theater recovery ICU (RICU). Patient characteristics, severity of illness, and outcomes were described according to the ICU where most of their bed-days occurred. Outcomes included duration of organ support and ICU admission, and mortality at 30 days. Mortality was compared between patients in PICU and the other adult ICUs, using a logistic regression model, adjusting for known confounding variables. Eighty-eight patients were included: 15 (17.0%) in PICU, 57 (64.7%) in AICU, and 16 (18.1%) in RICU. Patients' characteristics and illness severity on admission were comparable across locations, with similar organ support provided. Ten (66.7%) patients survived to hospital discharge from PICU, compared with 27 (47.4%) and nine (56.3%) patients from AICU and RICU, respectively, with no significant difference in 30-day mortality (OR 0.46, 95% CI 0.12-1.85;
