  3. Methodology

    Identified from intial search terms outside of OpenCodelists: "depress" "dysthymia" "sad" "melanchol" "dysthymic" mood" "unhappy"

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

    Candidate codelist uploaded to OpenCodelists for review of candidate codes.

    Excluded terms relating to antidepressant drugs or therapy, enhanced services administration, or depression annual reviews/monitoring as symptoms may have resolved due to treatment.

    Excluded terms related to depression screening as depression diagnosis/symptoms not necessarily present.

    Excluded depression due to clear causes, e.g., drugs such as amphetamines, pregnancy/childbirth.

    Excluded ambiguous terms related to change/disruption in mood, as could represent manic rather than depressive mood or biploar disorder. Excluded ambiguous mood disorders as not necessarily depression, e.g., could include bipolar disorder.

    Retained mixed anxiety and depression codes as suggests presence of depressive symptoms.
