What does interventional mean?
Interventional describes something that involves deliberate action intended to change a situation, outcome, or condition. It is especially common in medicine, where an interventional procedure is a treatment that actively addresses a problem rather than merely identifying or monitoring it; examples include interventional radiology, cardiology, and neuroradiology. In research and public policy, the adjective can refer to a planned action designed to test a hypothesis, improve performance, or produce a specific effect. The word is typically formal and technical rather than conversational. Its meaning generally emphasizes purposeful intervention, but it does not by itself indicate whether that intervention is successful, necessary, or appropriate. The related noun intervention names the action or measure, while intervene describes the act of stepping in.
