KDIGO hires an Evidence Review Team (ERT) as part of the development process for each of its guidelines. Before selecting an ERT, KDIGO issues a Request for Proposal based on the Scope of Work (SOW). Institutions with expertise in evidence synthesis submit proposals detailing their assessment of the key clinical questions based on the SOW, their methods for the evidence review and synthesis, description and credentials of all staff, proposed timeline for completion of the work, and budget. Proposals are evaluated for scientific merit, topic-specific expertise (especially in nephrology), understanding of the SOW, ability to create efficiencies in the process, and costs. Selection of an ERT is made jointly by the KDIGO Co-Chairs, Work Group Co-Chairs, and the KDIGO team.
