    Abstract:
    UNLABELLED: The ideology underpinning Paediatric Early Warning systems (PEWs) is that earlier recognition of deteriorating in-patients would improve clinical outcomes. OBJECTIVE: To explore how the introduction of PEWs at a tertiary children's hospital affects emergency admissions to the Paediatric Intensive Care Unit (PICU) and the impact on service delivery. To compare 'in-house' emergency admissions to PICU with 'external' admissions transferred from District General Hospitals (without PEWs). METHOD: A before-and-after observational study August 2005-July 2006 (pre), August 2006-July 2007 (post) implementation of PEWs at the tertiary children's hospital. RESULTS: The median Paediatric Index of Mortality (PIM2) reduced; 0.44 vs 0.60 (p<0.001). Fewer admissions required invasive ventilation 62.7% vs 75.2% (p=0.015) for a shorter median duration; four to two days. The median length of PICU stay reduced; five to three days (p=0.002). There was a non-significant reduction in mortality (p=0.47). There was no comparable improvement in outcome seen in external emergency admissions to PICU. A 39% reduction in emergency admission total beds days reduced cancellation of major elective surgical cases and refusal of external PICU referrals. CONCLUSIONS: Following introduction of PEWs at a tertiary children's hospital PIM2 was reduced, patients required less PICU interventions and had a shorter length of stay. PICU service delivery improved.
