In the comparison between EQ-5D pre-admission and at 3 months "same" means that the scores at 3 months were the same while "different" means that at least one score at 3 months was different in at least one EQ-5D item in comparison with that before surgery and ICU admission.

P: statistical significance according to chi square test, except for age, SAPS II, ICU and Hospital length of stay, and PTSS-14 (Mann Withney test).

a IQR: Inter Quartile Range

b Perceived severity of illness assessed by Numerical Rating Scale 0 to 10.
