Table 3. Program Characteristics Associated with Measuring Frailty at the Time of Kidney Transplant (KT) Evaluation and Admission for KT (n = 133).

Bolded results indicate statistical significance (P < 0.05). In practice, 31% of programs never measured, 44% of programs sometimes, and 25% always measured frailty during KT evaluation and 72% of programs never measured, 19% of programs sometimes, and 9% always measured frailty at admission for KT. For this analysis “sometimes” and “always” measured frailty were combined. This table identifies the independent associations between transplant center characteristics and the chance that they measure frailty at either evaluation or at admission for KT, separately; two separate models are presented below.

	Measurement of Frailty
	At Evaluation for KT PR (95% CI)	At Admission for KT PR (95% CI)
Adult KT volume	0.99 (0.95–1.03)	1.05 (0.95–1.16)
Age in years	0.73 (0.51–1.06)	0.44 (0.17–1.09)
Mean wait time
Quartile 1 (1 to 9.6 months)	Reference	Reference
Quartile 2 (9.7 months to 1 year and 2 months)	0.85 (0.65–1.10)	0.95 (0.24–3.75)
Quartile 3 (1 year and 2 months to 1 year and 8 months)	0.73 (0.54–0.98)	0.56 (0.14–2.21)
Quartile 4 (>1 year and 8 months)	0.78 (0.62–0.98)	0.81 (0.21–3.15)
% Male	1.15 (0.98–1.35)	1.54 (1.05–2.24)
% African American	0.95 (0.87–1.04)	0.99 (0.81–1.22)
% Hispanic	1.03 (0.96–1.11)	0.97 (0.78–1.20)
% Living donor	1.03 (0.95–1.03)	1.02 (0.79–1.32)
% older (>65y)	1.13 (0.89–1.45)	1.91 (1.10–3.32)
% Working for income	1.00 (0.90–1.12)	0.99 (0.74–1.34)
% Less than high school	0.95 (0.84–1.06)	1.15 (0.85–1.54)

Note: All program characteristics are scaled by 10%, except volume which was scaled by 25 transplants, and age which was scaled by 5 years. PR=Prevalence Ratio. Wait times are the time between evaluation and KT for both deceased and live donor recipients.
