This course aims to enhance the understanding and management of Desmopressin (DDAVP) challenges in patients. Participants will learn to recognize key drivers that lead to DDAVP challenge errors and understand the importance of timely lab draws for patients receiving test doses of DDAVP. The course will also cover the identification of barriers in obtaining appropriate laboratory testing after the administration of the DDAVP test dose. Additionally, participants will integrate interventions that have demonstrated a reduction in DDAVP challenge errors and analyze data obtained following the incorporation of these interventions. Through this comprehensive approach, the course seeks to improve patient outcomes and reduce errors related to DDAVP challenges.
