Case study 1
There is significant heterogeneity in the decision to hospitalise patients from the emergency department (ED). In this study, the Consortium aims at evaluating the propensity to hospitalise patients of the participating EDs, comparing the hospitalisation rate after adjusting for the differences among the case-mixes of the centres. An accurate and adjusted measure of the hospitalisation rate will be used to investigate the association between attitude of ED disposition decision and a short-term clinical outcome (i.e., 30-day survival).
