Multicenter Study
Peri-interventional outcome study in the elderly in Europe: A 30-day prospective cohort study.
The aim of this study was to describe the 30-day mortality rate of patients aged 80 years and older undergoing surgical and nonsurgical procedures under anaesthesia in Europe and to identify risk factors associated with mortality. ⋯ The estimated 30-day mortality rate of 4.2% was lower than expected in this vulnerable population.
