  2. Definition

    Severe mental illnesses (SMIs) refers to individuals with psychological problems that are so debilitating that their ability to engage in functional and occupational activities is severely impaired. In keeping with the literature (John et al., 2018), SMIs are divided into three categories: 1) schizophrenia-related disorders (schizophrenia) that include schizophrenia, schizotypal and delusional disorders, 2) bipolar disorder and other mood related disorders that include bipolar disorder, manic depressive episodes with psychotic symptoms, and 3) other psychotic disorders/SMIs.

    The attached lists of Read codes and ICD-10 for SMIs are based on John et al. (2018) and reviewed by two clinicians (Prof. Keith Lloyd and Prof. Ann John) in the study team. The codes in these lists exclude organic psychoses (e.g., drug and alcohol induced) and psychoses with origins in childhood. Additional Read codes for 'other psychotic disorders' that were mapped to the ICD-10 codes for acute and transient psychotic disorders (F23), depressive episodes/disorders with psychotic symptoms (F32.3 and F33.3) were added to the list as reviewed by two clinicians (Prof. Keith Lloyd and Prof. Ann John) in the study team and were used in published study (John et al., 2022). Information on algorithm construction are included in the following papers (Economou et. al. 2012; McGregor et. al. 2010).
