IMPROVED is an independent, international group of health professionals collaborating to develop core outcome sets and measures in dermatologic surgery. 

To the extent that the outcomes selected for inclusion in skin surgery clinical trials and observational studies can be agreed upon, study data can be better pooled, compared, and ultimately used to devise safer and more effective interventions.

The focus of IMPROVED is on diseases or conditions of the skin and subcutaneous tissues, particularly those that may be treated with procedural interventions, such as surgery, laser, or minimally invasive approaches.

IMPROVED is affiliated with the Cochrane Skin Group's Core Outcome Set Initiative (CSG-COUSIN), the international center for core outcome sets in skin disease.
