[ECLA grading: a system of acne classification for every day dermatological practice].

Area of Science:

• Dermatology
• Clinical Research

Background:

• Existing acne grading systems are primarily for clinical studies.
• Physicians need a practical tool for assessing acne lesions before and after treatment.

Purpose of the Study:

• To introduce and evaluate the ECLA grading scale for dermatological use.
• To assess the reliability of the ECLA scale among practitioners.

Main Methods:

• Development of the ECLA (Evaluation Cutaneous LAesions) scale by six French dermatologists.
• Assessment of intra- and inter-observer reliability for the ECLA scale.
• Evaluation of the scale's time efficiency (2 minutes).

Main Results:

• The ECLA scale demonstrated excellent intra- and inter-observer reliability, except for the retentional acne factor.
• Cross-physician reliability for retentional factors decreased over time, suggesting a need for specific training.
• The scale is quick and easy for practitioners to use.

Conclusions:

• The ECLA grading scale is a valuable and practical tool for dermatologists.
• It aids in monitoring acne patient progress and treatment efficacy.
• Specific training on retentional factors may enhance its utility in multicentric studies.
