We aimed to investigate the economic burden and cost-effectiveness evidence base for RKDs. Methods: We conducted a systematic scoping review to identify economic evaluations, health technology assessments, and cost-of-illness studies relating to RKDs, published since 2012. Results: A total of 161 published studies, including 66 cost-of-illness studies and 95 economic evaluations; 72 grey literature reports were also included. Most published literature originated from high-income nations, particularly the USA (81 studies), and focused on a handful of diseases, notably renal cell carcinomas (70) and systemic lupus erythematosus (36). Limited evidence was identified from lower-income settings and there were few studies of genetic conditions, which make up most RKDs. Some studies demonstrated the cost-effectiveness of existing treatments; however, there were limited considerations of broader economic impacts on patients that may be important to those with RKDs. Included health technology assessments highlighted difficulties in obtaining high-quality clinical evidence for treatments in very small patient populations, and often considered equity issues and other patient impacts qualitatively alongside clinical and economic evidence in their recommendations. Conclusion: We found large gaps in the economic evidence base for RKDs and limited adaptation of methods to account for the uniqueness of these diseases. There may be significant scope for innovation in building an investment case for RKD treatments, as well as in decision-making processes to inform investment decisions. date: 2024-12 date_type: published publisher: ELSEVIER SCIENCE INC official_url: https://doi.org/10.1016/j.ekir.2024.09.004 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 2328549 doi: 10.1016/j.ekir.2024.09.004 medium: Electronic-eCollection pii: S2468-0249(24)01922-3 lyricists_name: Gale, Daniel lyricists_id: DGALE18 actors_name: Gale, Daniel actors_id: DGALE18 actors_role: owner funding_acknowledgements: [Novartis] full_text_status: public publication: Kidney International Reports volume: 9 number: 12 pagerange: 3553-3569 pages: 17 event_location: United States issn: 2468-0249 citation: Angell, Blake; Wang, Siyuan; Gadsden, Thomas; Moorthy, Monica; Malik, Charu; Barratt, Jonathan; Devuyst, Olivier; ...
