Implementation of core outcome sets will help to ensure that critically important outcomes are consistently measured and reported in trials. Endorsement of the SONG outcomes is sought among key stakeholder organisations to support the use of core outcomes in trials in people with chronic kidney disease. This can help to improve the relevance and value of trials for informing decision-making among patients with chronic kidney disease and their healthcare providers.

Organisations that endorse the SONG outcome domains provide in-principle agreement of the following:

  • The aim of SONG is to establish core outcome domains based on their importance to patients, caregivers and health professionals for decision-making.
  • The process of SONG is transparent, evidence-based, and actively engages relevant stakeholder (patients, caregivers, and health professionals).
  • The SONG core outcomes should be reported in all trials involving patients on hemodialysis (SONG-HD) or transplantation (SONG-Tx). (Currently, core outcomes have been established for haemodialysis and kidney transplantation)
  • These outcomes are not designed to be comprehensive (to capture all the putative effects of interventions), but have been identified as the most critical to stakeholders of research in this setting.
  • They are not intervention specific and are limited in number.
  • Endorsement of the SONG core outcome domains does not cover specific measures for each core outcome. The development and validation of core outcome measures is currently underway.
  • The organisation will facilitate the dissemination and implementation of core outcome domains as appropriate.
