Generally risk is poorly understood and depends on past individual and professional perception and societal norms. In medical use the situation is further complicated by practical considerations of the ease with which risk can be measured and this seems to have driven much risk assessment work with a focus on objective measurements of cardiac function. The usefulness of risk assessment and the definition of risk is however in doubt because there are very few studies that have materially altered patient outcome based on information gained by risk assessment. This paper discusses these issues highlights areas where more research could usefully be performed and by defining limits for high surgical risk suggests a practical approach to the assessment of risk using risk assessment tools. Introduction What is a high-risk patient What do we mean by risk Why do we want to assess risk How do we want to use this analysis As intensivists we use risk assessment to identify a highly selected group of patients who are at such high risk of morbidity and mortality that they might benefit from high-dependency unit or intensive care unit ICU care perioperatively and we seek to identify those patients who might benefit from haemodynamic manipulation to improve these outcomes. The intensivist s perception of risk and aims of risk assessment may well differ from that of the patient carers and other doctors leading to communication difficulties. .
