The G-8 tool showed good screening properties for identifying elderly patients who could benefit from comprehensive geriatric assessment (CGA). This 8-item questionnaire is easy and fast to perform (4 - 5 minutes), even by medical staff untrained in geriatrics. In several studies, it provides an independent prognostic indicator for the overall survival of cancer patients.
The G-8 tool is not aimed at replacing expertise of geriatricians for the diagnosis of frailty. Rather, it should be used as a screening tool to identify patients in need for a further assessment and appropriate care.
