The Evolution of Quality of Life Assessment and Use in Dermatology

The creation of the Dermatology Life Quality Index (DLQI) questionnaire facilitated many studies on the impact of skin diseases on patients' quality of life (QoL). Many national and international guidelines recommend QoL assessment in dermatology, and some of them contain detailed recommendations on treatment goals and changes of treatment approaches based on DLQI score banding and minimal clinically important difference. The methodology of QoL in strument development and validation is constantly becoming more rigorous. Initiatives on selection of core outcome sets for skin diseases are focused on clinical trials but may also be beneficial for clinicians. There are various benefits of using QoL information in clinical practice, but experience of this is very limited at the moment. QoL assessment in dermatology is a rapidly developing field with a gradual shift from theory to practice.
