The "HepatoAINEs" program introduces information and communication technologies (ICTs) to identify patients with ACLD and prevent NSAIDs/metamizole prescription during perioperative care. The intervention includes guideline updates, automated alerts, and multidisciplinary support program (MSP) with collaboration among Digestive, Anesthesia, Surgery, and Pharmacy services to avoid the use of NSAIDs or metamizole in patients with ACLD scheduled for major surgery.
