Description of selected CRRT quality improvement metrics for this study.

Quality domain: structure
Provider
1. Specialized CRRT team	The number of multidisciplinary experts that constitutes the CRRT QI team
2. Education and training program	The number of education sessions for clinicians, ICU nurses and other healthcare professionals
Prescription
3. CRRT modality	The percentage of the total CRRT treatments that used CVVHDF as the main modality established by protocol
4. Anticoagulation	The percentage of the total CRRT treatments that used RCA
5. Total RCA/RCA-CRRT hours	The average total RCA hours divided by total CRRT hours in patients that used RCA
Quality domain: process
Performance
6. Delivered effluent dose	The average delivered CRRT effluent flow rate (ml/kg/h)
7. Delivered vs. prescribed effluent dose	The average delivered CRRT effluent dose divided by prescribed dose
8. Filter life span	The average time (in hours) of individual filter utilization
9. Filters per patient	The average total number of filters used divided by the total number of patients on CRRT
10. CRRT access alarms	The average number of CRRT access alarms per treatment day, reflecting catheter malfunction (high venous pressure in return line or low arterial pressure in access line)
11. Economic savings	The average gross total filter cost per 100-patient receiving CRRT
