On behalf of EORNA, the Scientific Committee, and the Local Organizing Committee, we are delighted to welcome you to the 12th EORNA (European Perioperative Nurses Association) Congress taking place from 14 to 16 May 2026. Since the first congress in 1997, EORNA has hosted congresses for its members and the international perioperative nursing community. Furthermore, our congresses have always been internationally recognized among experts in the field. The theme for this Congress is “The Synergy of Expertise and Knowledge”. It highlights the power of combining the specialized skills and experiences of perioperative nurses with the latest evidence-based knowledge. This synergy enhances patient care, improves surgical outcomes, promotes sustainability, and fosters a collaborative environment, where continuous learning and professional development are prioritized.
