Comparative Study
Incidence of delirium, risk factors, and long-term survival of elderly patients hospitalized in a medical specialty teaching hospital in Mexico City.
We determined the incidence, probable risk factors, causes, and long-term survival of delirium in patients hospitalized in a medical specialty teaching hospital in Mexico City. ⋯ In this geriatric population of Mexican patients, delirium incidence was similar to that previously reported in the worldwide literature. Its incidence is associated with longer hospital stay and greater mortality. Age, low level of schooling, greater comorbidity, high glucose levels, poor pain control, and hematocrit lower than 30% were independently associated with a greater incidence of delirium.
