Insights
Pandemic influenza A(H1N1) may significantly increase demand for UK paediatric intensive care units (PICUs). Regional variations in critical care provision necessitate enhanced paediatric retrieval services to manage increased winter activity.
Area of Science:
- Pediatric Intensive Care
- Epidemiology
- Public Health
Background:
- Seasonal respiratory viruses cause significant unplanned admissions to UK paediatric intensive care units (PICUs).
- Pandemic influenza A(H1N1) disproportionately affects children, potentially straining PICU resources.
Purpose of the Study:
- To project paediatric intensive care unit (PICU) demand during a pandemic using current data.
- To analyze the impact of regional variations in critical care bed availability on pandemic preparedness.
Main Methods:
- Utilized the FluSurge 2.0 model for demand estimation.
- Employed age-stratified UK population data and conservative epidemiological parameters.
Main Results:
- A substantial portion of existing paediatric intensive care unit (PICU) capacity may be required during the pandemic peak.
- Significant regional disparities in critical care provision exist across the UK, leading to varied pandemic impacts.
Conclusions:
- Contingency planning is essential to address the anticipated rise in paediatric intensive care needs due to pandemic influenza.
- Paediatric retrieval services are crucial, especially given the uneven distribution of critical care resources regionally.
Background:
Each winter seasonal respiratory virus infections account for large variations in unplanned admission to UK paediatric intensive care units (PICU). The emergence of pandemic influenza A(H1N1) has been associated with a notable predominance in children and may be expected to have a significant impact on PICU provision.
Aims:
To derive conservative projections for PICU demand from current data and examine the effect of regional variations in bed provision.
Methods And Results:
PICU demand was estimated with the FluSurge 2.0 model using age-stratified data for the UK population and recently published conservative estimates for epidemiological parameters. The data suggest that a significant proportion of current total capacity may be required at the peak of the pandemic. Variation in per capita critical care provision across the UK leads to a wide range in potential impact at a regional level.
Conclusions:
Contingency measures for children needing paediatric intensive care are needed to absorb the likely increase in activity expected due to pandemic influenza this winter. Because of variations in provision by region, the role of paediatric retrieval services will be especially important.
