  2. Definition

    The read codes and algorithms used to identify depression have been developed and utilised in previous research (Cornish et al., 2016; John et al., 2016). These code lists include diagnosis and symptoms of depression, administrative codes relating to depression and depression codes specific to childhood and adolescence. Codes identifying prescriptions are to be used in combination with a previous diagnosis or treatment (John et al, 2015). The algorithm encompassing a historical diagnosis which is currently being treated in combination with a current diagnosis which is treated or untreated improves sensitivity from using current diagnosis alone. This method was optimal for identifying common mental disorders in primary care.
