Each recipient is awarded a plaque, monetary award, and complimentary registration to the Annual Scientific Sessions. Grading of Recommendations Assessment, Development and Evaluation (GRADE) comprehensive track workshop travel grant The Heart Rhythm Society (HRS) leadership and the Scientific and Clinical Documents Committee (SCDC) leadership have identified a need to provide resources to writing groups engaged in development of clinical practice documents, in order to increase the reliability and validity of document structure, recommendations, and implementation. One aspect of this enhancement program is to assign each writing group a member with skill in methodology of document creation. We aim to increase the number of available HRS methodology writing group members by specific training workshops. These workshops will serve as the foundation for improved development of clinical documents, systematic reviews, and clinical practice guidelines. The HRS will provide one travel grant up to $2500 to attend the Grading of Recommendations Assessment, Development and Evaluation (GRADE) comprehensive track workshop, which provides training and learning the principles of evidence-based medicine and guideline development for clinical or public health recommendations. There are 16+ hours of intensive hands-on training in small group settings with six facilitators and a maximum attendance of 44 participants. More details for the workshop can be found at https://www.gradeworkinggroup.org. The expectations for the recipient would include willingness to contribute in the following ways: 1. Provide a summary presentation of the learnings at a future SCDC meeting 2. Participate on a clinical document project as a writing committee member with an eye toward the methodological aspects of clinical document development 3. Participate in discussions within the SCDC to improve the HRS methodology for developing clinical documents, and ultimately guidelines.</ExplanationTxt>
