Funded by the National Institute for Health Research (NIHR), the study that led to the production of the Paediatric Admission Guidance in the Emergency Department (PAGE) tool was designed to support better decision-making in paediatric emergency departments about whether children need to be admitted to hospital or can be discharged home safely.\ud \ud The study was conducted over more than 12 months in three dissimilar emergency departments and an urgent care centre. A partnership of the University of Salford, the University of Manchester, and the University of Leicester (and Leicester Hospitals) together with the Northern Care Alliance NHS Group completed the study which has moved into a reporting and dissemination phase including the publication of supporting documentation.\ud \ud A huge sample of 44,501 children and young people participated in this study which has allowed robust analysis of the factors that exert the greatest impact on predicting the need to admit or the safety of discharging children who attend such departments. Moreover, the diversity of the departments in the study indicates that the PAGE instrument (tool) should be effective across the country in a variety of emergency department facilities. PAGE was the highest recruiting research study in England in 2018-2019, and is the highest recruiting paediatric study and third highest recruiting study of any specialty in the history of the whole National Institute for Health Research Clinical Research Network.\ud \ud The supporting documentation includes:\ud 1. What is PAGE?\ud 2. PAGE - comparison with other scores and systems\ud 3. PAGE - cut point considerations
