Updating the diagnosis, classification and assessment of rosacea: recommendations from the global ROSacea COnsensus...

Area of Science:

• Dermatology
• Ophthalmology
• Clinical Classification

Background:

• Current rosacea diagnosis relies on subtype classification.
• Phenotypes can overlap subtypes, complicating diagnosis and research.
• A phenotype-led approach may improve patient-centered care.

Framework:

• International consensus established a phenotype-led rosacea diagnosis and classification scheme.
• Modified Delphi approach involved 20 international experts (17 dermatologists, 3 ophthalmologists).
• Electronic and blinded voting ensured objective consensus.

Implementation:

• Consensus reached on a phenotype-based approach for rosacea diagnosis and classification.
• Persistent centrofacial erythema and phymatous changes identified as independently diagnostic.
• Flushing, telangiectasia, inflammatory lesions, and ocular manifestations were not deemed individually diagnostic.

Implications:

• Shift towards phenotype-based diagnosis enhances clinical practice and research.
• Agreement on phenotype severity measures and patient burden assessment.
• Facilitates standardized, patient-centered rosacea management globally.
