Core Outcome Measures in Effectiveness Trials

A core outcome set for clinical trials of Traditional Chinese Medicine for Sjogren's syndrome

General Information

Objective: To develop a core outcome set (COS) for Sjogren's Syndrome treatment by traditional chinese medicine, which should assist in standardizing outcome selection, collection and reporting in future research studies.
Methods: Drawing on the guidance and approaches of the Core Outcome Measures in Effectiveness Trials (COMET), this study uses a four-phase mixed-methods design: (1) Focus groups and interviews with key stakeholder groups (patient living with Sjogren's Syndrome, researchers and clinician) and a review of the literature will be undertaken to build a long list of outcomes; (2) Three rounds of Delphi surveys will be used with key stakeholder groups. Statements for the Delphi surveys and participation processes will be developed and informed through substantial member involvement with patient living with Sjogren's Syndrome and clinician; (3) A consensus meeting will be convened with key participant groups to discuss the key findings and finalize the COS.
Discussion: We hope that the COSs will lead to an improvement in the quality of evidence-based
clinical practice, enhance patient care, and improve the quality and consistency of research.
