Core Outcome Measures in Effectiveness Trials

ICHOM: A Standard Set of Core Outcome Measures for Children and Young People with Anxiety, Depression, and OCD

General Information

The ICHOM Standard Set of outcomes for anxiety, depression and OCD in children and young people is a project that will involve an international working group of leading clinicians, measurement experts, and patients. The aim of the working group will be to produce a recommendation of the outcomes that matter most to patients with these conditions. This will enable providers to start measuring outcomes in a standardised way and better understand how to improve the lives of their patients.

Focus group(s)
Literature review
Semi structured discussion

ICHOM facilitates and organises monthly teleconference meetings with the Working Group members to develop the Standard Set in a structured way. This process involves the following steps:

• Defining how we classify the population of patients
• Compiling a list of outcome measures in use by national or regional outcome measurement efforts (including national audits) as well as those in use by leading programs and validated patient-reported outcomes that have been reported in the medical literature
• Defining a prioritised list of outcomes that assess success in managing these conditions from the patient’s perspective
• Agreeing on the best available instrument or definition to measure each domain
• Defining necessary baseline case-mix adjustment variables in order to make comparisons possible
• Developing a reference guide that describes instruments that should be used, and that provides users with the necessary background information to adopt the Standard Set
• Publishing the complete Standard Set of outcomes in a leading journal and present at conferences
• Making the Standard Set accessible and freely available to all
