Proportion of patients with ultrafiltration rates ≥13 ml/h per kilogram after application of varied hypothetical treatment time extension paradigms

Facility TT Change	UF Rate ≥13 ml/h per kg before TT Extension, % (no. of patients)	UF Rate ≥13 ml/h per kg after TT Extension, % (no. of patients)
Extend TT by 15 min if TT is <240 min	19.4 (20,152)	15.8. (16,418)
Extend TT by 30 min if TT is <240 min	19.4 (20,152)	12.8 (13,332)
Extend TT to 240 min if TT is <240 min	19.4 (20,152)	11.0 (11,395)
Extend TT long enough to achieve UF rate <13 ml/h per kg if TT is <240 min	19.4 (20,152)	3.1 (3199)
Extend TT long enough to achieve UF rate <13 ml/h per kg regardless of TT	19.4 (20,152)	0.0 (0)

Estimation of TT extension was on the basis of the monthly Kidney Care Quality Alliance cohort from January of 2012 (n=103,850). TT, treatment time; UF, ultrafiltration.
