Geriatric 8 Scale to Predict Functional Decline in Older Adults With Cancer: a Systematic Review (original) (raw)

Background: to determine the operative characteristics of the Geriatric Scale 8 versus the Comprehensive Geriatric Assessment to detect older adult patients with cancer at risk of functional decline. Methods: we conducted a systematic search for studies in three major indexed databases: Medline (PubMed), Embase and Google Scholar. We selected studies from 2010-2020, considering criteria such as older adults with some type of cancer, in which the G8 scale has been applied and has been associated with functional decline. Results: we found 690 relevant titles. After reviewing the titles, abstracts, and full articles, we selected two articles that met the inclusion criteria. From these articles, we found a sensitivity of 81%, a specificity of 38%, a positive likelihood ratio of 1.21 and a negative likelihood ratio of 0.63. Conclusions: We conclude that the G8 scale has a good sensitivity for the detection of functional decline in older adults with cancer, however, the scale does not hav...
