Of patients aged 70 or older, about 25 percent will come into the typical hospital already having some symptoms of delirium – but an additional 25 percent will develop hospital-acquired delirium during their hospital stay. Patients with delirium are likely to stay in the hospital longer, fall more, be readmitted sooner. Hospital-acquired delirium comes from medication interactions, infections, recovery from surgery, and other not fully understood causes. There are 200 hospitals that have adopted the Hospital Elder Life Program (HELP) http://www.hospitalelderlifeprogram.org/ which makes use of trained volunteers, primarily, to help older patients avoid hospital-acquired delirium.
