Background: Worldwide, several bodies produce renal guidelines, potentially leading to duplication of effort while other topics may remain uncovered. A collaborative work plan could improve efficiency and impact, but requires a common approved methodology. The aim of this study was to identify organizational and methodological similarities and differences among seven major renal guideline bodies to identify methodological barriers to a collaborative effort. Methods: An electronic 62-item survey with questions based on the Institute of Medicine standards for guidelines was completed by representatives of seven major organizations producing renal guidelines: the Canadian Society of Nephrology (CSN), European Renal Best Practice (ERBP), Kidney Disease Improving Global Outcome (KDIGO), Kidney Health Australia-Caring for Australians with Renal Insufficiency (KHA-CARI), Kidney Disease Outcome Quality Initiative (KDOQI), Sociedad Latino-Americano de Nefrologia e Hipertension (SLANH) and United Kingdom Renal Association (UK-RA). © Nephrology Dialysis Transplantation

Background and objectives Fatigue is a very common and debilitating symptom and identified by patients as a critically important core outcome to be included in all trials involving patients receiving hemodialysis. A valid, standardized measure for fatigue is needed to yield meaningful and relevant evidence about this outcome. This study validated a core patient-reported outcome measure for fatigue in hemodialysis. Design, setting, participants, & measurements A longitudinal cohort study was conducted to assess the validity and reliability of a new fatigue measure (Standardized Outcomes in Nephrology-Hemodialysis Fatigue [SONGHD Fatigue]). Eligible and consenting patients completed the measure at three time points: baseline, a week later, and 12 days following the second time point. Cronbach α and intraclass correlation coefficient were calculated to assess internal consistency, and Spearman rho was used to assess convergent validity. Confirmatory factor analysis was also conducted. Hemodialysis units in the United Kingdom, Australia, and Romania participated in this study. Adult patients aged 18 years and over who were English speaking and receiving maintenance hemodialysis were eligible to participate. Standardized Outcomes in Nephrology-Hemodialysis, the Visual Analog Scale for fatigue, the 12-Item Short Form Survey, and Functional Assessment of Chronic Illness Therapy–Fatigue were used. Results In total, 485 participants completed the study across the United Kingdom, Australia, and Romania. Psychometric assessment demonstrated that Standardized Outcomes in Nephrology-Hemodialysis is internally consistent (Cronbach α =0.81–0.86) and stable over a 1-week period (intraclass correlation coefficient =0.68–0.74). The measure demonstrated convergence with Functional Assessment of Chronic Illness Therapy–Fatigue and had moderate correlations with other measures that assessed related but not the same concept (the 12-Item Short Form Survey and the Visual Analog Scale). Confirmatory factor analysis supported the one-factor model. Conclusions SONG-HD Fatigue seems to be a reliable and valid measure to be used in trials involving patients receiving hemodialysis. © 2020 by the American Society of Nephrology.
