Introduction: There is ongoing controversy concerning the potential influence of industry and financial conflict of interest (FCOI) in the development of clinical practice guidelines (CPG). The influence of industry in renal guideline development has been discussed in the past with emphasis on the National Kidney foundation (NKF) and Kidney and Dialysis Outcomes Quality Initiative guidelines. In this study we evaluate the self-reported FCOI among guideline panel members in Kidney Disease: Improving Global Outcomes (KDIGO) CPGs. Methods: We examined 10 of the most recent KDIGO CPGs developed between 2009 and 2018. Using disclosure lists, we catalogued FCOIs for panelists for each individual CPG. The categories were Advisor/Consultant, Honoraria, Travel Stipend, Grant/Research Support, Speaker, Equity Interest, Employee, Board of Trustees, Royalties, Advisory Board, Employment, Ownership, Data Monitoring Committee, Expert Testimony, and Development of Education Materials. We also reviewed FCOIs for members of evidence review team (ERT). We also catalogued the company involved in each disclosure. One conflict describes 1 instance of participation of an individual in 1 category in each guideline. “Company” describes a commercial, industry, or institute affiliation reported in each episode. Results: One hundred two (66.4%) of the total 151 panelists reported FCOI. A total of 662 conflicts were disclosed. Being a consultant or advisor was the most common category. One hundred fifty-one companies were associated with FCOI disclosure. One company was most frequently reported, involving 60 (9%) of 662 conflicts. Of the 52 members in the ERT, there was 1 instance of FCOI. Conclusion: FCOI is prevalent in KDIGO guidelines with almost two thirds of the panelists self-reporting FCOI. The evidence review team had only 1 instance of FCOI.
