Table 3

Outcomes of patients on continuous renal replacement therapy for acute kidney injury categorized according to the median of the filter life span (20 hours).

	Filter life span <20 hours (N = 44)	Filter life span ≥20 hours (N = 51)	value
Bleeding complication	5 (11.4)	5 (10.0)	0.83
ICU mortality, N (%)	22 (50)	30 (58.8)	0.39
Hospital mortality, N (%)	25 (56.8)	33 (64.7)	0.43
Mechanical ventilation duration (days), mean ± SD	23.8 ± 31.2	19.5 ± 19.1	0.44
ICU length of stay (days), mean ± SD	27.9 ± 32.4	25.0 ± 17.6	0.61
Hospital length of stay (days), mean ± SD	58.9 ± 86.3	61.5 ± 66.6	0.87
