Frailty Is Associated With Increased Care Dependence in Patients Following Major Vascular Surgery.

OBJECTIVE

To assess if frailty scoring can predict increased frailty and care dependence requiring a change in living situation in patients with peripheral artery disease (PAD) following major vascular surgery.

DESIGN

A single center, retrospective cohort study.

SETTING

Fiona Stanley Hospital, a tertiary center located in Perth, Western Australia.

PARTICIPANTS

Seventy-nine patients with PAD who underwent major vascular surgery at the study hospital in 2022 were enrolled.

INTERVENTION: Baseline Clinical Frailty Scale (CFS) scores were assigned retrospectively. A quantitative analysis using two partitions, CFS 1-3 (not frail) versus 4-9 (frail) was used. Cases were screened for hospital-acquired complications, and records were reviewed to assess the level of care dependence at the time of discharge and 6 months following.

MEASUREMENTS AND MAIN

RESULTS

The primary outcome was to assess if frailty predicts increased care dependence. Secondary outcomes included unplanned readmissions and hospital-acquired complications in this cohort. A logistic regression was performed to predict the effects of age and baseline, discharge, and 6-month CFS on the likelihood of change in living situation. Baseline frailty was associated with a higher frailty score at discharge (p = 0.001), which persisted at 6 months (p = 0.001). There was no difference in American Society of Anesthesiologists classification, sex, age, 30-day mortality, or in-hospital complications between groups. After correcting for age, a lower baseline CFS (odds ratio 0.19, confidence interval 0.04-0.84, p = 0.028) and discharge CFS (odds ratio 34.00, confidence interval 3.88-298.42, p = 0.001) predicts the likelihood of patients having a change in living situation after surgery.

CONCLUSIONS

Frail patients with PAD undergoing major vascular surgery are at significant risk of functional decline, necessitating a change in living situation to meet their increased care needs. This increased care dependence persisted 6 months following discharge.
