Characteristics and outcome of Emergency Department intubation in geriatric patients

IntroductionThe number of elderly patients admitted to the Emergency Department (ED) continues to grow due to the natural aging of the population. Consequently, tracheal intubation will be increasingly used in the oldest old. The objective of this retrospective study is to evaluate the characteristics and outcome of patients of 75years and older undergoing an endotracheal intubation in the ED.MethodsIn a single center, retrospective study we reviewed digital medical files of patients of 75years and older in the period from 1/01/2008 to 31/12/2010, who were admitted to the ED of the Universitair Ziekenhuis Brussel in Brussels, Belgium and underwent endotracheal intubation. Survival served as primary outcome and survival without sequelae as secondary endpoint.ResultsIn the study period, 88 patients of 75years and older were intubated in the ED. Sixty three (72%) patients died after intubation and 25 (28%) survived until discharge. All 23 patients (26%), who were intubated during cardiopulmonary resuscitation died. A survival rate of 48% was observed in patients, who were intubated for respiratory failure (28%), intracerebral hemorrhage or ischemic stroke (17%), cardiac failure (8%) or other reasons. Non-survivors were significant older, of male sex, had higher APACHE scores and more frequently used cholesterol lowering drugs.ConclusionSenior adults, aged 75years or older and undergoing endotracheal intubation at the ED, have a high mortality rate. Younger age and female sex at admission were positively correlated with survival. Of those who left the hospital, one-third were able to return home without major sequelae.
