PREOPERATIVE ASSESSMENT INDEXES	CATEGORY EVALUATED
G8 score	Health status. Evaluates 1. decline of food intake, 2. weight loss, 3. mobility, 4. Neuropsychological problems, 5. BMI, 6. more or less than 3 prescription drugs, 7. Age, 8. comparison with other people of the same age[14-15].
sFI frailty index	Frailty. 1. diabetes mellitus, 2. functional status, 3. history of chronic obstructive pulmonary disease, 4. history of congestive cardiac failure, and 5. hypertension requiring treatment[9].
Johns Hopkins frailty assessment calculator	Frailty. Five phenotypic criteria: unintentional weight loss, exhaustion, low energy expenditure, low grip strength, and/or slowed walking speed[21].
CGA	Frailty functional status, fatigue, comorbidity, cognition, mental health, social support, nutrition and geriatric syndromes (e.g. dementia, delirium, falls, incontinence, osteoporosis or spontaneous fractures, neglect or abuse, failure to thrive, constipation, polypharmacy, pressure ulcers, and sarcopenia)[23].
ASA physical status classification	Health status. Assessing the fitness of patients before surgery five classes (I to V)[11,14].
mini-COG assessment	Cognitive status. Consists of two components, a 3-item recall test for memory and a simply scored clock drawing test[14,18].
Karnofsky score and ECOG performance status	Physical function. Performance status. ECOG 0-5, Karnofsky score 0-100[14,19-20].
CISR-G and CCI	Comorbidities. CISR-G 14 categories. CCI 17 categories, Predicts 10-year survival in patients[14,16-17].
