oXirisNet Registry: A Prospective, National Registry on the oXiris Membrane.

Worldwide, the widespread use of extracorporeal blood purification therapies (EBPTs) is progressively increasing in everyday clinical practice, particularly in critical care settings. The efficacy of EBPTs on removal of inflammatory mediators is already well established in the literature. Nonetheless, clinical research is particularly cumbersome in this setting, and many clinical trials aiming at exploring the effect of EBPTs on outcomes have failed in demonstrating consistent results regarding 28-day- or hospital-mortality rates. In recent years, data emerging from large registries have been increasingly used to provide real-world evidence on the effectiveness, quality, and safety of EBPTs. The philosophy behind this-Italian Registry is a renewal of the concept of "clinical research" in the field of EBPTs applied to critically ill, septic patients with or without acute kidney injury. The platform used for the registry-specifically designed for research purposes and fed by clinical data prospectively observed-promotes good practice with a positive and active interaction with the physician/researcher. This interaction has favorable real-time effects for the specific patient, providing "bed-side clinical feedbacks," similarly to the decision support system. Examples of these issues are bundles reminders, suggestions for drug adjustment according to the extracorporeal clearance, clinical calculator for body mass index, or mechanical ventilation setting. The platform-physician interaction has additional useful effects on the single utilizing center, providing "mid-term, center-specific clinical feedbacks." These generally consist of clusters of data taken over a certain period, for example, regarding patients' outcome, microbiological data, or use of disposable for EBPTs.
