Disease State: Atopic eczema / Atopic dermatitis / Eczema



HOME is a global initiative involving patients, healthcare professionals, journal editors, regulatory authorities and the pharmaceutical industry to establish a consensus-agreed core outcome set for eczema (homeforeczema.org).

Despite a high burden of atopic eczema, evidence-based clinical care and decision making is limited by the use of multiple, unvalidated outcome measures. A systematic review (Charman et al. 2003), showed that only 27% of the 93 included trials utilize a published severity scale, with the remainder using modified versions of published scales or un-named scales with no data on validity or reliability. Another systematic review (Schmitt et al. 2007) showed that most named outcome measurements for eczema have not been tested sufficiently and have inadequate performances related to validity, reliability, or ease of use.

HOME was founded in 2008 by Professors Hywel Williams and Jochen Schmitt to bring together the eczema research community to standardise outcome measures by agreeing a core outcome set to be included in all eczema clinical trials. 

Scope of the intended COS:

  • Study types: Clinical Trials. A core set for clinical practice and use in registries is also being developed alongside the clinical trials core outcome set
  • Region: Global


Project Goal

To develop a consensus-based core outcome set (COS) for clinical trials and a clinical practice set.


Current Status

Consensus on core outcome domains and instruments has been achieved. The focus of HOME is now on implementation of the core set.

Home developed the methodological Roadmap for development of a core outcome set and has followed this roadmap (along with other guidance from COMET and COSMIN).
