The Geriatric-8 (G8) is a rapid screening instrument derived from Mini Nutritional Assessment items plus age. It is widely used in older adults, especially oncology pathways, to identify those who may benefit from comprehensive geriatric assessment. Lower G8 scores suggest greater vulnerability, and a threshold of 14 or below is commonly considered abnormal.
Formula: G8 total = sum of 8 item scores (range 0-17). Common abnormal threshold: <=14.
A cutoff <=14 is commonly used to select older adults who should receive comprehensive geriatric assessment.
Lower G8 scores indicate higher vulnerability and support referral for comprehensive geriatric assessment.
Use in older adults, especially oncology or complex chronic-care pathways, when rapid geriatric vulnerability triage is needed.
G8 is screening-focused and may miss domain-specific issues unless followed by broader multidimensional assessment.
