    Burnout explained: WHO definition, causes, measurement and fixes

    WHO's ICD-11 describes burn-out as an occupational phenomenon, not a medical condition. It is a syndrome resulting from chronic workplace stress that has not been successfully managed, marked by exhaustion, mental distance or cynicism about one's job, and reduced professional efficacy.[1][2] Research links it to workload, control, reward, community, fairness and values at work, and meta-analyses find organisation-directed interventions help more than individual ones.[3][4] In AMA surveys, 41.9% of US physicians reported at least one burnout symptom in 2025, down from 53% in 2022.[5]

    “Burnout” is used loosely for almost any exhaustion. The World Health Organization uses the term more narrowly: it describes a work-related syndrome and is not classed as a medical condition.[1] This page explains the definition, how researchers measure burnout, what drives it and what the evidence says helps.

    This page is not medical advice. Researchers debate how far burnout overlaps with depression, so if you are struggling, talk to a doctor or other qualified clinician rather than assuming it is “just burnout”.[6]

    The WHO definition

    WHO’s International Classification of Diseases (ICD-11) lists burn-out as an “occupational phenomenon”. It is a reason people may seek care, not an illness.[1] It describes burn-out as the result of long-term workplace stress that has not been managed well, with three features: feeling drained or exhausted; feeling distant from, negative or cynical about your job; and feeling less effective at work.[2] WHO says the term applies only to work, not to other parts of life.[7]

    ICD-11 places burn-out in the chapter “Factors influencing health status or contact with health services”, which covers reasons for contact that are not illnesses.[1] It defines burn-out as “a syndrome conceptualized as resulting from chronic workplace stress that has not been successfully managed”, with exhaustion, increased mental distance or cynicism, and reduced professional efficacy.[2] The term is restricted to the occupational context.[7] Burn-out was already in ICD-10 in the same category; ICD-11 gives a more detailed definition.[8]

    How it is measured

    Christina Maslach and Michael Leiter describe burnout as a psychological syndrome arising from chronic interpersonal stressors at work. Its three dimensions are overwhelming exhaustion, cynicism and detachment, and a sense of ineffectiveness.[9] The Maslach Burnout Inventory (MBI) was designed to measure those three dimensions. It was the first burnout measure built on comprehensive psychometric research and is considered the standard research tool.[10] Because burnout has no agreed diagnostic criteria, a 2015 review of 92 studies concluded that its distinction from depression is conceptually fragile.[6] Questionnaires like the MBI are research and workplace tools, not a way to diagnose yourself.

    What causes it

    Research across many occupations has identified six organisational domains linked to burnout: workload, control, reward, community, fairness and values.[3] WHO similarly says poor working environments, including excessive workloads, low job control and job insecurity, pose a risk to mental health. It estimates 12 billion working days are lost each year to depression and anxiety.[11]

    What helps: the evidence

    The main meta-analyses are of doctors. They find that interventions do reduce burnout, and that changing how work is organised tends to help more than programmes aimed only at individuals.[12][4] WHO recommends that employers change working conditions, for example through flexible working or policies against violence and harassment.[13]

    • A 2016 Lancet meta-analysis of 15 randomised trials and 37 cohort studies in physicians found overall burnout fell from 54% to 44%. Both individual-focused and organisational strategies produced meaningful reductions.[12]
    • A 2017 meta-analysis of controlled studies in 1,550 physicians found small benefits overall, larger for organisation-directed interventions than physician-directed ones.[4]
    • Maslach and Leiter noted a relative lack of evaluative research on interventions.[14] Evidence outside medicine, and from long-term randomised trials, is thinner.

    Health workers

    Much burnout research has focused on health care.[15] CDC found the share of US health workers reporting burnout very often rose from 11.6% in 2018 to 19.0% in 2022, and reports of harassment at work more than doubled.[16] The US Surgeon General issued an advisory, Addressing Health Worker Burnout, in 2022.[17] As CDC researchers summarised it, the advisory emphasises improving the work environment rather than asking workers to be more resilient.[18] Among US physicians, AMA surveys show burnout falling for three years: 41.9% reported at least one symptom in 2025, down from 53% in 2022.[5] The 2025 figures come from nearly 19,000 responses across 106 organisations. Emergency medicine (49.8%) and urological surgery (49.5%) were highest.[19][20]

    Burnout, as WHO defines it, is tied to the workplace, whereas an ADHD diagnosis requires symptoms that began before age 12.[7][21] A clinician can help sort out overlapping causes. See ADHD in adults for how ADHD is assessed.

    Questions readers ask

    Is burnout a medical diagnosis?

    No. WHO includes burn-out in ICD-11 as an occupational phenomenon, not a medical condition, in the chapter on factors influencing health status or contact with health services.[1]

    What are the three signs of burnout?

    ICD-11 describes three dimensions - feelings of energy depletion or exhaustion; increased mental distance from one's job, or negativism or cynicism about it; and reduced professional efficacy.[2]

    Can you have burnout from caregiving or parenting?

    Under WHO's definition, burn-out refers specifically to the workplace and should not be used to describe experiences in other areas of life.[7]

    How is burnout measured?

    The most common research tool is the Maslach Burnout Inventory, the first burnout measure built on a comprehensive programme of psychometric research and considered the standard research tool.[10]

    Is burnout the same as depression?

    Researchers disagree. A 2015 review of 92 studies concluded the distinction is conceptually fragile, partly because burnout has no agreed diagnostic criteria.[6]

    What reduces burnout?

    Meta-analyses in physicians found that both individual and organisational strategies reduce burnout, with larger effects for organisation-directed interventions. WHO recommends that employers change working conditions through organisational interventions.[12][4][13]

    How common is burnout among doctors?

    In AMA survey data, 41.9% of US physicians reported at least one symptom of burnout in 2025, down from 43.2% in 2024, 48.2% in 2023 and 53% in 2022.[5]
