EQ-5D and VAS mean scores of surgical patients. Grey: period 1 = before implementing the rapid response system; black: period 2 = after implementing the rapid response system; 3 m. = 3months after surgery, 6m. = 6 months after surgery; EQ-5D = Euroqol 5, scale -0.33 - 1; VAS = visual analogue scale 0–100; RRS = rapid response system. Pre-surgery: fixed factors: gender, American Society of Anaesthesiologists’ physical status (ASA-PS), covariates: age at admission. Following surgery: fixed factors: gender, ASA-PS, covariates: age at admission, planned intensive care length of stay not because of a serious adverse event, EQ-5D dimension pre-surgery. *Not all patients filled in the VAS score.
