Core Outcome Measures in Effectiveness Trials

Developing a Core Outcome Set for Children with Chronic Wet Cough

General Information

The aim of this project is to develop a Core Outcome Set for the treatment of chronic wet cough in children (excluding cystic fibrosis) which can be used in clinical and cost effectiveness studies. This will be undertaken in accordance with the Core Outcome Sets - Standards for Development (COS-STAD) document.

Nature / type of Intervention


Consensus meeting
Delphi process
Semi structured discussion
Systematic review

1. Systematically review current literature to identify outcomes used in previous intervention studies for children with chronic wet cough.
2. Identify outcomes important to parents of children with chronic wet cough through semi structured interviews and outcomes important to children with chronic wet cough through group discussions.
3. Conduct Delphi survey with key stakeholders to prioritise outcomes. Stakeholders will include general practitioners, paediatric respiratory nurse specialists, secondary care paediatricians and tertiary care respiratory paediatricians.
4. Hold a consensus meeting where the prioritised outcome list will be discussed between key stakeholders and parent/child representatives to generate a COS.
