The continuously increasing elderly population (≥80 years) in Europe suggests a dramatic growth in the number of elderly patients undergoing a variety of surgical and non-surgical interventional procedures. Little is known about the peri-interventional mortality rates and outcome in this specific elderly population.

The POSE Group Business meeting will take place at Euroanaesthesia on Monday June 4th 08h30-10h00 at Meeting Room 18-19


Primary: To determine the peri-interventional (surgical and non-surgical interventional) all-cause mortality rate on day 30.

Secondary: To assess an array of post-interventional major complications and functional and cognitive outcome until the post-interventional day 30.
