Core Outcome Measures in Effectiveness Trials

The COMPARE (Core Outcome Measures PAediatRic Endocrinology) Initiative

General Information

The COMPARE (Core Outcome Measures PAediatRic Endocrinology) Initiative is an international not-for-profit research collaboration working towards an international consensus on definitions and standardised outcome measures for therapeutic trials (and epidemiological studies) in Paediatric Endocrinology.

The outcomes are developed based on shared priorities between patients, families and caregivers, clinicians, researchers, policy makers and other relevant stakeholders.

Principal investigator: Dr Richard G McGee

The process is based on the methods used in many other research areas, in particular the Outcome Measures in Rheumatology (OMERACT) initiative and the World Health Organisation (WHO)-endorsed OMERACT framework. This process is underpinned by the values of: partnership, transparency, equity, trust, respect, evidence, and diversity.
Each ‘domain’ will run individually under the guidance of the COMPARE steering group. For example, the COMPARE-Diabetes group will develop core outcomes for trials related to paediatric diabetes.
There is a five phase process to the creation of a core outcome set: study protocol, systematic review of published outcomes, online Delphi survey, consensus workshop, and publication of core outcome set.
