Delirium, dementia and in-hospital mortality: the results from the Italian Delirium Day 2016, a national multicenter study

There is little evidence about the prevalence of cognitive disorders and their effect on in-hospital mortality in large multicenter studies. The objectives of the 2016th edition of the "Italian Delirium Day", a large multicenter study on in-hospital older patients, were to assess: 1) the point-prevalence of cognitive impairment/no dementia, dementia, delirium and delirium superimposed on dementia, DSD; and 2) the effect of these conditions on in-hospital mortality.
