About us

The American Society for Enhanced Recovery (ASER) was founded in 2014. It is a nonprofit organization with an international membership, and is dedicated to promoting the practice of optimizing patient preparation and recovery through education and research.


To advance the practice of perioperative enhanced recovery, to contribute to its growth and influence, and to foster and encourage research, education, public policies and programs and scientific progress.


The concept of Enhanced Recovery of fast-track surgery originated from the work of Professor Henrik Kehlet in Denmark in the 1990s. The ERAS Society in Europe was formed in 2010. The first international ERAS Society Congress was held in France in 2012.

In the USA interest in Enhanced Recovery has been growing since the late 2000s. The Duke University Medical Center Enhanced Recovery Program started in 2010. Since then many centers around the country have started Enhanced Recovery programs.

The first US Enhanced Recovery congress, sponsored by Duke University, was held in Washington DC in 2013. The 2nd US Enhanced Recovery program was held in New Orleans in October 2014, and marked the official launch of the American Society of Enhanced Recovery (ASER).
