Report and Journal Articles of research for the overall objective is to examine school completion, education performance and health outcomes of children who have been hospitalised with an injury or a chronic health condition (i.e. diabetes, epilepsy, asthma, or mental health conditions). This will be a population-based case-comparison study of injured or chronically ill children aged ≤18 years at the date of admission for their index hospitalisation in NSW. It will include a matched population-comparison group. The research will involve linkage of records from the NSW hospitalisation data to school outcomes from the National Assessment Plan for Literacy and numeracy (NAPLAN), school enrolment information, school completions (year 10/11/12), and healthcare utilisation and outcomes (i.e. emergency department (ED) presentation, ambulatory mental health client contacts, mortality). The comparison group will be selected from the NSW registry of births.
