In the eye of the storm: impact of COVID-19 pandemic on admission patterns to paediatric intensive care units in the UK and Eire.

BACKGROUND: The coronavirus disease-19 (COVID-19) pandemic had a relatively minimal direct impact on critical illness in children compared to adults. However, children and paediatric intensive care units (PICUs) were affected indirectly. We analysed the impact of the pandemic on PICU admission patterns and patient characteristics in the UK and Ireland. METHODS: We performed a retrospective cohort study of all admissions to PICUs in children < 18 years during Jan-Dec 2020, using data collected from 32 PICUs via a central database (PICANet). Admission patterns, case-mix, resource use, and outcomes were compared with the four preceding years (2016-2019) based on the date of admission. RESULTS: There were 16,941 admissions in 2020 compared to an annual average of 20,643 (range 20,340-20,868) from 2016 to 2019. During 2020, there was a reduction in all PICU admissions (18%), unplanned admissions (20%), planned admissions (15%), and bed days (25%). There was a 41% reduction in respiratory admissions, and a 60% reduction in children admitted with bronchiolitis but an 84% increase in admissions for diabetic ketoacidosis during 2020 compared to the previous years. There were 420 admissions (2.4%) with either PIMS-TS or COVID-19 during 2020. Age and sex adjusted prevalence of unplanned PICU admission reduced from 79.7 (2016-2019) to 63.1 per 100,000 in 2020. Median probability of death [1.2 (0.5-3.4) vs. 1.2 (0.5-3.4) %], length of stay [2.3 (1.0-5.5) vs. 2.4 (1.0-5.7) days] and mortality rates [3.4 vs. 3.6%, (risk-adjusted OR 1.00 [0.91-1.11, p = 0.93])] were similar between 2016-2019 and 2020. There were 106 fewer in-PICU deaths in 2020 (n = 605) compared with 2016-2019 (n = 711). CONCLUSIONS: The use of a high-quality international database allowed robust comparisons between admission data prior to and during the COVID-19 pandemic. A significant reduction in prevalence of unplanned admissions, respiratory diseases, and fewer child deaths in PICU observed may be related to the targeted COVID-19 public health interventions during the pandemic. However, analysis of wider and longer-term societal impact of the pandemic and public health interventions on physical and mental health of children is required.

Transport of critically ill children to paediatric intensive care units in the UK and Ireland: 2013-2022.

OBJECTIVE: To explore the trends and changes in the transport of children to paediatric intensive care units (PICUs) between 2013 and 2022. DESIGN: Retrospective analysis of routinely collected data. PATIENTS: Children transported for care in a PICU in the UK and Ireland aged<16 years. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: There were 43 058 transports to a PICU involving 36 438 children from 2013 to 2022 with the majority of children requiring only one transport. The number of transports increased from 4131 (2013) to 4792 (2022). Over the study period the percentage of children aged under 1 year who were transported decreased from 50.2% to 45.2% and similarly, the percentage who were invasively ventilated also decreased from 81.1% to 70.2%. Conversely, the use of non-invasive ventilation during transports increased slightly from 4.0% to 7.0%. The percentage of transports where a parent was able to accompany the child increased over time (2013: 66.2% to 2019: 74.9%), although there were reductions due to the COVID-19 pandemic and requirements for social distancing (2020: 52.4%). CONCLUSIONS: We have demonstrated an increased use of specialist paediatric transport services and changes in the PICU population over time. Routine data collection from the transport services provide a means to measure improvements and changes over time in the service provided to critically ill children and young people who need transport to the PICU.
