Comparison of ultrafiltration practice between physicians and nurses. a Methods to achieve ultrafiltration during continuous renal replacement therapy. Nurses were more likely to achieve ultrafiltration by varying ultrafiltration rate, while physicians were more likely to vary both ultrafiltration and replacement fluid rates (p < 0.001). b Frequency of net fluid balance assessment during continuous renal replacement therapy. Nurses were more likely to check fluid balance every hour, while physicians were more likely to check fluid balance every 4–24 h (p < 0.001). c Interventions to performed for hemodynamic instability during net ultrafiltration. Compared with physicians, nurses were more likely to stop fluid removal, administer a fluid bolus, and start or increase the dose of vasopressors (p < 0.05 for all responses). d Perceptions related to barriers for successful implementation of net ultrafiltration. Compared with physicians, nurses were more likely to cite barriers such as patient intolerance (p < 0.05), frequent interruptions (p < 0.001), whereas physicians were more likely to cite under prescription (p < 0.05)
