The ISN World Congress of Nephrology, taking place in Yokohama, Japan, from March 28-31, 2026, has applied for accreditation by the European Accreditation Council for Continuing Medical Education (EACCME®). The final decision will be shared on this page by the end of 2025.

Through an agreement between the Union Européenne des Médecins Spécialistes and the American Medical Association, physicians may convert EACCME® credits to an equivalent number of AMA PRA Category 1 Credits™. Information on converting EACCME® credit to AMA credit can be found at www.ama-assn.org/education/earn-credit-participation-international-activities. Live educational activities, occurring outside of Canada, recognised by the UEMS-EACCME® for EACCME®’s are deemed to be Accredited Group Learning Activities (Section 1) as defined by the Maintenance of Certification Program of the Royal College of Physicians and Surgeons of Canada.
