The study investigates a novel anaesthesiological clinical decision support (CDS) application, that integrates risk evaluation tools and updated clinical guidelines guided by artificial intelligence in the setting of preoperative anaesthesiological assessment. It will be compared to the current standard preoperative assessment workflow with participants being actual patients. 480 participants will be randomly assigned to either the CDS group (preoperative assessment using the CDS application) or the Control group (standard preoperative assessment workflow).

Preoperative anaesthesiological assessment and risk evaluation using a clinical decision support application, that calculates perioperative risks for the patient and informs the anaesthesiologist on indicated diagnostics and procedures according to clinical guidelines in real-time.
Preoperative anaesthesiological assessment using standard procedures of the hospital. In addition a sham clinical decision support application will be used. Information on perioperative risks and indicated diagnostic procedures according to clinical guidelines is not given to the physician.

Number of clinically not indicated preoperative diagnostic procedures ordered by the anaesthesiologist
Preoperative diagnostic procedures ordered by the anaesthesiologist are defined as ECG, echocardiography, carotid (Duplex) ultrasound, chest X-ray and functional non-invasive tests for coronary artery disease (e.g. stress echocardiography)
Time frame: preoperative assessment until operative procedure
Number of documented items from a predefined set of relevant cardiovascular symptoms and conditions during the anaesthesiological assessment
Completeness of medical documentation will be measured by the number of documented items from a predefined list of relevant cardiovascular symptoms and conditions during the preoperative anaesthesiological asssessment.
Time frame: preoperative assessment until operative procedure
Incidence of intra- and postoperative complications
Time frame: operative procedure until hospital discharge, assessed up to 4 weeks
Incidence of 30-Day unplanned All-cause Hospital Readmission
Time frame: hospital discharge until 30th postoperative day
Length of Hospital Stay
Time frame: hospital admission until hospital discharge, assessed up to 4 weeks
