Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Incidence of postoperative delirium	Postoperative delirium was assessed using the 3D-CAM scale. It consists of 4 features, and a positive feature 1 and 2 plus 3 or 4 is considered postoperative delirium.	Within 7 days after surgery. Delirium at any time during the 7 days after surgery was considered postoperative delirium.
Secondary	Systolic pressure	"just entering the operating room", "immediately after intubation", "every 5 minutes after intubation until the patient leaves the operating room".	Up to 5 hours in the operating room
Secondary	Diastolic pressure	"just entering the operating room", "immediately after intubation", "every 5 minutes after intubation until the patient leaves the operating room".	Up to 5 hours in the operating room
Secondary	Mean pressure	"just entering the operating room", "immediately after intubation", "every 5 minutes after intubation until the patient leaves the operating room".	Up to 5 hours in the operating room
Secondary	Heart rate	"just entering the operating room", "immediately after intubation", "every 5 minutes after intubation until the patient leaves the operating room".	Up to 5 hours in the operating room
Secondary	Incidence of postoperative admission to ICU	Including immediate postoperative admission to ICU and postoperative admission to ICU in the ward.	Up to 1 month after surgery
Secondary	Length of stay in ICU	Duration of stay in ICU after surgery	Up to 1 month after surgery
Secondary	Postoperative pain	The degree of postoperative pain was assessed using the Numerical Rating Scale (NRS). The pain level increased sequentially from 0-10	Within 7 days after surgery
Secondary	Maximum postoperative C-reactive protein (CRP)	Only the highest CRP values detected in the normal course of gastrointestinal surgery are collected, and no additional blood sampling or interventions are performed	Up to 1 month after surgery
Secondary	Minimum postoperative albumin	Only the lowest albumin values detected in the normal course of gastrointestinal surgery are collected, and no additional blood sampling or interventions are performed	Up to 1 month after surgery
Secondary	Length of hospitalization	The total number of days the patient spent at the hospital for the current consultation	After the patient is discharged from the hospital, average 1 month
Secondary	Complication	All the perioperative complications are recorded	During the perioperative period, up to 1 month after surgery
