Development of a core outcome set for pharmacist interventions in chronic kidney disease (COSP-KD): a protocol for e-Delphi consensus study

Background: Research has demonstrated the benefits of interventions delivered by pharmacists in people with chronic kidney disease (CKD). However, significant variation exists for reported outcomes and the inconsistency in measures used limits effective interpretation of the evidence. This can be addressed by developing a core outcome set (COS), which are the minimum outcomes that should be measured and reported across all trials for a particular therapeutic area.

Aims: To develop a COS for clinical trials evaluating the effectiveness of interventions involving pharmacists in people with CKD.

Methods: An online survey, e-Delphi survey, and a consensus workshop will be conducted.

Findings: The findings of this study will be published in a peer‐reviewed journal, where the results will be presented in lay language with appropriate infographics online and via social media.

Conclusion: The development of a pharmacist-specific COS in CKD will address a gap for achieving consensus in outcomes and improve the consistency of outcomes reported.
