Clinical Trial Summary
A prospective observational cohort study to assess the predictive value of preoperative
frailty on postoperative quality of life in peripheral vascular surgery patients.
Description:
Introduction:
The percentage of elderly in the general population is increasing rapidly. Currently, the
Dutch population comprises for one fifth of persons aged 65 years or older and recent
estimates show this will increase to roughly a quarter in the next 20 years. Since th
incidence of peripheral arterial disease increases with age, this rise in elderly will also
reflect on the population of patients being referred for vascular surgery. Elderly patients
are at higher risk for postoperative complications, mortality or functional decline than
younger patients. In frail elderly this effect might be more pronounced. Frailty is an
umbrella term that encompasses patient related factors such as weight loss, muscle wasting,
inactivity, comorbidities and polypharmacy. Current scoring systems that are used to predict
postoperative mortality and complications following vascular surgery perform poorly in the
elderly population and do not take into account frailty. Moreover they are designed to
predict mortality and complications and are not validated to predict patient reported outcome
measures such as quality of life or functional status. The aim of the AGE VASC study is
assess the value of frailty factors in predicting an improvement in quality of life one year
after peripheral vascular surgery.
Methods:
The AGE VASC study is a prospective observational cohort study. All patients aged 70 years or
older, scheduled for peripheral vascular surgery of the lower limb, mentally competent and
have signed informed consent are eligible for the study. Before surgery patients will be
screened for frailty using different questionnaires and physical tests. The battery of tests
exists of Short Form 36 (SF36), Walking Impairment Questionnaire (WIQ), Multi Nutritional
Assessment (MNA), Montreal Cognitive Assessment (MoCA), Nagi's scale for disability,
Geriatric Depression Scale -8 (GDS8), three physical tests: five meter walking speed, timed
get up and go test and hand grip strength. And a non-invasive measurement of Advanced
Glycation Endproducts (AGEs). A blood sample will be taken to determine vitamin status,
immune status and iron deficiency. After surgery, electronic patients charts will be studied
to score postoperative complications or mortality. Three and twelve months after surgery
patients will receive SF-36, WIQ, and World Health Organization Disability Assessment
Schedule (WHODAS) 2.0 questionnaires to determine quality of life and functional status.
