Prevalence and risk factors associated within 48-hour unplanned paediatric intensive care unit readmissions: An integrative review

Abstract

BackgroundUnplanned paediatric intensive care unit (PICU) readmission is associated with increased morbidity/mortality, hospital length of stay, and health service cost and is recognised as a key performance indicator of quality-of-care delivery. However, research evidence on unplanned PICU readmission risk factors is limited, and results were inconsistent across studies. AimThe aim of this experiment was to collate and synthesise unplanned within-48-h PICU readmission prevalence and associated risk factors. MethodsAn integrative review was conducted, guided by a five-stage framework. Seven electronic databases were searched (2013–30th June 2023). Studies published in English with full-text accessibility and detailed methodologies were included. The quality of included studies was critically appraised using the Joanna Briggs Institute checklists. Prevalence and risk factors were extracted, synthesised, and presented narratively. ResultsTen studies met eligibility criteria and reported a varied readmission rate from 0.008% to 6.49%. Fifteen types of significant risk factors were extracted. Twelve consistently cited risk factors were age, weight, complex chronic conditions, admission source, unplanned admission, PICU length of stay, positive pressure ventilation, discharge disposition, oxygen requirements, respiratory rate, heart rate, and Glasgow Coma Score at discharge. Of the 12, five predictors were classified as modifiable factors, including discharge disposition, oxygen requirement, abnormal respiratory rate, abnormal heart rate, and decreased Glasgow Coma Score at discharge. ConclusionThis review acknowledges the complexity of confounding factors impacting unplanned PICU readmission and the lack of standardisation examining potential risk factors. The five modifiable factors are suggestive of clinical instability and premature PICU discharge. Patients with modifiable risk factors should have their readiness for discharge re-evaluated. Scaffolding support to manage patients at risk of readmission includes senior bedside nursing allocation, use of PICU outreach services, and 1:2 nurse-to-patient ratios in the ward setting, which are warranted to ensure patient safety.
