  2. Definition

    This codelist was taken from OpenCodelists, created by OpenSAFELY. We recommend viewing this Phenotype on the OpenCodelist website to view the most recent version.

    Code list aiming to identify individuals consulting complaining of anxiety symptoms and with anxiety diagnoses.

  3. Methodology

    Identified from intial search terms outside of OpenCodelists: "anxiety" "anxio" "nueroses" "neurosis" "neurotic" "worry" "worried" "hypervigilan" "angst" "panic" "phobia" "fear" "adjustment" "stress" "nervous" "unease" "terror" terrify" "terrified" "hysteri" "afraid" "apprenhen"

    Clearly irrelevant codes excluded (not reviewed by a second clinician)

    Candidate codelist uploaded to OpenCodelists for review of candidate codes.

    Retained named phobias.

    Retained terms relating to anxiety about specific circumstances (e.g., Anxiety about vomiting in public), as still indicate anxiety.

    Retained terms relating to anxious depression, as still indicate presence of anxiety. Retained terms with anxious and depressive symptoms. However excluded neurotic depression, as implies primary depressive state.

    Excluded terms about counselling for anxiety or anxiolytic drugs, as symptoms may have been resolved by therapy. Excluded terms relating to resolved anxiety, or anxiety screening.

    Excluded terms related postpartum and drug-induced anxiety (e.g., cocaine), as clear cause of symptoms, not likely to be related to covid.

    Retained all "fear of x" codes, as unclear if these represent reasonable fears (e.g., fear of infection with a particular virus following exposure) or unfounded fears related to anxiety (e.g., fear of open spaces).

    Excluded terms related to stress monitoring or anxiety disorder clinic, as not necessarily anxious (symptoms may have resolved).

    Excluded organic anxiety disorders, as related to clear underlying diagnosis.

    Excluded terms specifying 'neurosis or psychosis' as could be due to psychosis.
