The Charta of Vicenza

work group was created [13] . This year, the summit followed an intense activity of discussion and interaction to achieve a consensus on the meaning of the terminology used, a homogenization of the abbreviations and a common definition for hardware components, techniques and operations in machines and platforms for acute extracorporeal therapies. The initiative resulted in 2 manuscripts that will be subject to further evaluation by the experts and will eventually be published in the near future. The meeting, however, was characterized by a strategic plan with the commitment of all parties to carry this initiative forward. All participants signed a document called the ‘Charta of Vicenza’. A large number of professionals, academic experts, investigators and scientists agreed on the content of the document and signed it (appendix 1). In figure 1 , we report the first page of the document. Figure 2 reports the historical photo at the end of the summit with a group of participants involved in the final discussion of the nomenclature. The text reported in the document, that was signed, is the following: We, the participants of the Vicenza 2015 NSI, agree to make any possible effort to standardize the nomenclature of CRRTs and to homogenize its terminology in manuscripts, books, machine software and data collection registries of the future. The opportunity to standardize the terminology used in continuous renal replacement therapies (CRRTs) and extracorporeal techniques for acute kidney injury (AKI) and other critical illnesses has been discussed in multiple occasions. We took advantage of the large crowd gathered in Vicenza, for the 2015 International Course on Critical Care Nephrology, to reinforce this concept and expand the level of consensus. We organized a summit with a board of worldwide experts and most producers of CRRT machines in order to generate a terminology consensus. The group was defined as the Nomenclature Standardization Initiative (NSI) alliance. Such an alliance among academicians and producers had the homogenization of the terminology used in extracorporeal therapies and related techniques as its main mission. It is not the first time that Vicenza sees the birth of important initiatives in the area of AKI. In 1995, a consensus group was created to produce the first nomenclature consensus in the area of CRRTs, and since then a continuous effort has always been made to maintain high the attention to this matter [1–6] . The first Acute Dialysis Quality Initiative meeting, held in Vicenza in 2002, gave origin to RIFLE and the universal definition of AKI, and many other achievements have subsequently been made by this consensus group [7–12] . Later, the Michelangelo Retreat, also held in Vicenza, gathered members from different scientific societies of the world and the Acute Kidney Injury NetPublished online: July 22, 2015
