Feasibility study of an online modifiable Enhanced Recovery After Surgery protocol with specific focus on opioid avoidance.

Background: The high and increasing rate of opioid use is a serious issue in the Western world affecting the population's physical and mental health. In most cases, opioid dependency starts with prescriptions by medical professionals, so efforts aimed at reducing in-hospital opioid use should result in less long-term dependency. The aim of the current study was to evaluate the feasibility of implementing an opioid-scarce protocol as part of a new online modifiable Enhanced Recovery After Surgery (mERAS) programme.
