Influenza vaccine administration in a paediatric intensive care unit.

Abstract

We describe the clinical profile of children and outcomes of influenza immunisation for patients in a paediatric intensive care unit (PICU). Over two influenza seasons: 19/04/2018 to 07/08/2018 and 02/05/2019 to 10/10/2019, an immunisation nurse and PICU nurse coordinator met weekly and identified patients to receive the influenza vaccine. An inpatient list of PICU patients was screened for eligible patients: greater than 6 months of age, did not have imminent procedures (e.g. surgery) or were not critically unwell, as determined by the treating team, to receive the influenza vaccine. Patients were excluded if they had undergone surgery in the previous 24 hours or were being treated palliatively. Sixty patients in PICU were identified, with 43% (26/60) receiving the vaccine while in PICU and 17% (10/60) once discharged from PICU to the general ward environment. The majority of patients immunised were in PICU due to cardiac surgery/cardiology or general medical conditions, such as cerebral palsy or RSV bronchiolitis. There were no reported adverse events following immunisation. We have demonstrated the suitability and acceptability of children in the PICU receiving the seasonal influenza vaccine and tailored interventions to follow-up once discharged from PICU to optimise protection.
