Introduction: Frailty has been proven to lead to higher morbidity and mortality rates in surgical patients, independent of age. The modified Frailty Index (mFI) is a validated means of assessing for frailty.
Aim of study: The aim of this study is to ascertain if the mFI correlates with clinician experience in turning down patients for abdominal aortic aneurysm (AAA) surgery and/or AAA surveillance.
Methods: A contemporaneously recorded database of all AAA patients treated during 2017 at a large University Hospital was reviewed. Patients were categorised into the following groups; continued surveillance, turned down for surveillance, patient declined surveillance, patient offered surgery, patient turned down for surgery and patient declined surgery.
Results: One hundred and forty two patients were included. Twenty-eight patients <5.5 cm were turned down for surveillance with a mFI of 0.27. Forty-one patients <5.5 cm continued with surveillance, with a mFI of 0.09 (p < 0.0001). Eighteen patients >5.5 cm were turned down for surgical intervention with a median mFI of 0.36. Forty-two patients were offered surgical intervention had a median mFI of 0.09 (p < 0.0001).
Conclusion: Frailty is associated with higher morbidity and mortality amongst frail patient cohorts. mFI is a valid and easy to use tool to predict perioperative outcomes in AAA intervention. It correlates well with senior, experienced clinicians' decision-making in relation to who should and who should not undergo elective AAA surgery and those patients who should have ongoing aneurysm surveillance.
