Inclusion criteria
Inclusion criteria: Patient participants: 1. Elective surgical patients entering the routine preoperative assessment workflow at either of the two campuses during the study period; 2. Scheduled to receive general anesthesia, neuraxial anesthesia, peripheral nerve block, or other anesthesia requiring preoperative assessment by the anesthesiology department; 3. Complete preoperative electronic medical record available. Anesthesiologist participants: 1. Junior anesthesiologists currently practicing in the anesthesia and surgery center of the institution, in principle with <= 5 years of clinical anesthesia experience; 2. Voluntary participation with written informed consent.
Exclusion criteria
Exclusion criteria: Patient exclusion criteria: Exclude those undergoing emergency surgery, those receiving only local infiltration anesthesia without the need for systematic preoperative evaluation by the anesthesiology department, and those with critical documents or key fields missing in the electronic medical record, making it impossible to establish effective reference labels. Anesthesiologist exclusion criteria: Exclude those unwilling to participate in the study or who withdraw midway, those unable to complete the required case evaluations due to rotation arrangements during the study, and those who have been deeply involved in establishing the gold standard of this study, making it impossible to meet blinding requirements.
