Core Outcome Measures in Effectiveness Trials

Standardised outcomes in nephrology – Haemodialysis (SONG-HD): establishing a core outcome set in haemodialysis

General Information

The Standardised Outcomes in Nephrology-Haemodialysis (SONG-HD) study aims to establish a core outcome set for haemodialysis [hemodialysis] trials, to improve the quality of reporting, and the relevance of trials conducted in people on haemodialysis.

SONG-HD is a five-phase project that includes the following: a systematic review to identify outcomes that have been reported in haemodialysis systematic reviews and trials; nominal group technique with patients and caregivers to identify, rank, and describe reasons for their choices; qualitative stakeholder interviews with patients, caregivers, clinicians, researchers, and policy makers to elicit individual values and perspectives on outcomes for haemodialysis trials; a three-round Delphi survey with stakeholder groups to distil and generate a prioritised list of core outcomes; and a consensus workshop to establish a core outcome set for haemodialysis trials.
