Table 2.

Agreement between clearance decisions for elective surgery in 204 patients at high perioperative risk using digital guideline support and an expert's decision compared with the agreement of standard clearance decisions with an expert's decision. The values are the number of patients (%) whose preoperative evaluation with the respective approach was judged correct or incorrect by the expert. Correctly evaluated patients were either correctly cleared or correctly rejected (non-clearance) for surgery. Patients with incorrect evaluations were either incorrectly cleared for surgery because examinations were not performed that the expert considered necessary (not followed recommendations) or incorrectly not cleared for surgery because unnecessary examinations were requested (incorrectly rejected).
