ERA Model 2018 - personalised patient outcomes prediction after endovascular aneurysm repair of abdominal aortic aneurysms

The interactive Endovascular
Aneurysm Repair Risk Assessment (ERA) Model, originally developed in 2008, is
updated and improved. Vascular surgeons enter preoperative variables for a
patient undergoing EndoVascular Aneurysm Repair (EVAR) and the ERA Model estimates that patient's
individualised expected outcomes. The new model uses variables that are
routinely collected preoperatively, and hence can be used to support surgeon-patient
discussions prior to the operation. Patients can be fully informed of potential
risks based on individualised assessments of likely outcomes following elective
EVAR surgery.

Outcomes include: 1 and 3 year
survival, 30 and 90 day mortality, Early and mid-term endoleaks, operative and
complication likelihoods.

Pre-operative variables are fitness (fit or unfit), ASA, history of stroke-TIA, age, aneurysm angle, infrarenal neck
length, white cell count, respiratory assessment, diabetes and use of statins.
