Table 3 Secondary outcome measures against patient frailty status

From: Utility and reliability of the Clinical Frailty Scale in patients scheduled for major vascular surgery: a prospective, observational, multicentre observer-blinded study

Secondary outcome measur Non-frail (n = 49) Pre-frail (n = 15) Frail (n = 3)
Procedure Open AAA 29 (59.2%) 3 (20.0%) 0
Bypass graft 2 (4.1%) 3 (20.0%) 0
EVAR 18 (36.7%) 9 (60.0%) 3 (100%)
Postoperative critical care admission (n, % proportion)   40 (81.6%) 11 (73.3%) 2 (66.7%)
Length of stay (mean, (SD)) Critical care 2 (2.41) 5 (8.07) 1 (0.07)
Hospital 7 (4.84) 7 (6.24) 3 (0.58)
In-hospital mortality (n, % proportion)   0 (0%) 2 (13.3%) 0
30-day readmission (n, % proportion) 5 (7.9%) 0 0
Major morbidity: Clavien-Dindo Score ≥ 3A-5 (n, % proportion) 10 (20.4%)* 2 (13.3%) 0
  1. Surgical procedure, number of critical care admissions, discharges home, in-hospital mortality and 30-day readmission (values as numbers and proportions of their frailty subgroup). The total length of critical care and hospital length of stay. Values are the mean and standard deviation [SD]
  2. *Clavien-Dindo morbidity scores were unavailable for two patients in the non-frail group
