Safety of the Manchester Triage System to identify less urgent patients in paediatric emergence care: a prospective observational study

Objective To assess hospitalisation rate as a proxy for the ability of the Manchester Triage System (MTS) to identify less urgent paediatric patients. We also evaluated general practitioner (GP) services to determine if they met patients' needs compared to emergency department care. Methods Self-referred children triaged as less urgent by the MTS in two emergency departments in the Netherlands were included in a prospective observational study. Therapeutic interventions during emergency department consultation, hospitalisation after consultation and determinants for hospitalisation were assessed using logistic regression analysis. Results During emergency department consultation, extensive therapeutic interventions were performed more often in patients with extremity problems (n=175, 19%) and dyspnoea (n=30, 15%). 191 (3.5%) of 5425 patients were hospitalised. Age and presenting problem remained statistically significant in multivariable logistic analysis, predicting hospitalisation with ORs of 3.0 (95% CI 2.2 to 4.1) for age <1 year, 2.5 (1.5 to 4.1) for dyspnoea, 3.5 (2.5 to 4.9) for gastrointestinal problems and 2.8 (1.1 to 7.2) for patients with fever without identified source compared to all other patients. 3975 (76%) of 5234 patients were contacted for follow-up after discharge. Six (0.15%) patients were hospitalised after emergency department discharge. Conclusion In the MTS less urgent categories, overall hospitalisation is low, although children
