Enhanced Recovery After Surgery: a patient centered process.

The Enhanced Recovery After Surgery (ERAS) is a model of care introduced in 1997 by a group of general surgeons from Northern Europe led by Henrik Kehlet. The core of this approach is to produce improvements in surgical patient outcomes, especially in the reduction of hospital stay, complications rate, early recovery and reduction of economic burdens. Simply elaborating and establishing a protocol is not enough and much more efforts and changes are needed to achieve the aim to offer a sustainable improvement in the overall quality of patient care, therefore, ERAS is not a single and rigid protocol but is a method, a "modus operandi", a new way of multidisciplinary teamwork with readiness to make changes as knowledge evolves, i.e., a revolution of medical-scientific thought: we have to move from the concept of "management of disease" to that of "health promotion".
