Methods and materials
- A retrospective study was performed in which patients admitted to our mental health unit with a diagnosis of FEP from 31st May 2017 to 31st May 2019 were identified via medical record search
- Inclusion criteria: patients aged 16 and above with a diagnosis of FEP or an admission with a primary psychotic disorder (as per DSM-V), non-organic or organic psychosis and no evidence of prior contact with mental health services, as documented on the hospital discharge summary or in the clinical notes
- Exclusion criteria: patients where the imaging referral was specifically for delirium or dementia
- Imaging request forms, studies and reports were obtained from the hospital’s PACS system
- The emergency department (ED) and admission notes were examined for further information regarding imaging indications
- Image findings were classified into incidental (clinically non-significant), clinically relevant with a possible but unlikely causal link to psychosis and clinically relevant with a probable causal link to psychosis
- Relevant statistical calculations were performed in STATA (v16)
