According to the legislation (Statutory Instrument 256 of 2018), HIQA must justify:
- any new practices that involve exposing patients to ionising radiation before they are generally adopted*
- existing practices that involve exposing patients to ionising radiation, if new and significant information becomes available about the efficacy or safety of the practice itself or about any alternative practice that could replace it
*generally adopted means the practice is used for broad categories of patients, rather than individual patients. The process whereby HIQA approves a practice for a broad category of patients is also known as ‘generic justification’.
