Table 1. The modified geriatric assessmenta.

Domain	Scale	Range	Rated by	Cutoff value for frailty	Rationale for cutoff values
Activities of daily living	EORTC QLQ-C30 Q5b		Patient	If reported yes a little/quite a bit/very much on the question ‘Do you need help with eating, dressing, washing yourself or using the toilet’	ADL-deficiencies previously used in frailty classifications of cancer patients (Balducci and Extermann, 2000)
Comorbidity	OARSc	0–15 (Higher score indicates more comorbidities)	Patient	>3 points	Threshold for shorter survival in previous study of cancer patients (Klepin et al, 2014)
Medications, polypharmacy	ATCd	0–13	Nurse/ MD	>7 regular medications (ointments & common vitamins excluded)	Previously used in frailty classifications of cancer patients (Ommundsen et al, 2014)
Physical function	TUGe		Nurse	>14 seconds	Similar cut-offs (⩾14/>14.5) used to identify GA deficits in cancer trials (Owusu et al, 2011; Jolly et al, 2015; Williams et al, 2015)
Cognitive function	MMSEf	0–30 (Higher score indicates better function)	Nurse	<24 points	Previously used in frailty classifications of cancer patients (Ommundsen et al, 2014)
Depressive symptoms	GDS-15g	0–15 (Higher score indicates more symptoms)	Patient	⩾7 points	Chosen to ensure high specificity (Friedman et al, 2005; Cullum et al; 2006)
Nutritional status	PG-SGAh		Nurse/Patient	Considered severely malnourished by nurse or self-reported weight loss ⩾10% the last 6 months.	Weight loss ⩾ 10% the last six months is generally considered as an indicator of severe malnutrition (Nitenberg and Raynard, 2000)
Falls			Nurse	Patient reports ⩾2 falls the last 6 months	Previously used to identify GA deficits in cancer trials (Owusu et al, 2011; Jolly et al, 2015)
