Burn-out is included in the 11th Revision of the International Classification of Diseases (ICD-11) as an occupational phenomenon. It is not classified as a medical condition.

It is described in the chapter: ‘Factors influencing health status or contact with health services’ – which includes reasons for which people contact health services but that are not classed as illnesses or health conditions.

Burn-out is defined in ICD-11 as follows:

“Burn-out is a syndrome conceptualized as resulting from chronic workplace stress that has not been successfully managed. It is characterized by three dimensions:

• feelings of energy depletion or exhaustion;
• increased mental distance from one’s job, or feelings of negativism or cynicism related to one's job; and
• reduced professional efficacy.

Burn-out refers specifically to phenomena in the occupational context and should not be applied to describe experiences in other areas of life.”
