Our hypothesis is that this abbreviated geriatric screening tool will be a better predictor for surgical and oncologic complications after surgery than performance status alone (which is currently the only measure of fitness used in routine oncology care). In addition, we predict that parts of the TOGA, specifically the instrumental activites of daily living score (IADL), mini nutritional assessment (MNA) and the brief fatigue inventory (BFI), will be the strongest predictor(s) of outcomes in our thoracic surgery population. The outcomes data we generate will also be important in quality improvement and standardization of preoperative risk assessment for elderly patients with thoracic malignancies.
