Vascular surgical operations are major procedures with significant associated morbidity and mortality. Frailty is a major factor influencing surgical outcome, but the effect on morbidity/mortality and quality of life is poorly understood in vascular surgery. Activity levels play a significant role in frailty and in pre-intervention preparation. It is anticipated that as frailty levels increase, activity levels decrease. It is hypothesised that vascular surgery patients suffer from a high prevalence of frailty and that increasing frailty will lead to increased morbidity and mortality and decreased quality of life.
This initial study will provide the foundations to identify targets for improvement in degree of frailty, appropriateness for surgery and outcome.
This project aims to:
Assess and quantify the prevalence of frailty as well as recording activity levels in the vascular surgery patient cohort Explore the impact of frailty and pre-op activity on surgical outcomes in the vascular surgical patient cohort to guide surgical treatments as well as future studies aimed at improving frailty and activity and thereby quality of life.
Identification of an appropriate metric of frailty for this population group to include activity, is a secondary aim of this proposal.
