When deciding upon new interventions or strategies, these novel actions should at least prevent or lower the risk of an adverse event to occur.

In any case, an intervention is expected to change risk. A newly introduced intervention may decrease the probability of an event to happen and/or can have an effect on its impact. Some interventions have a diagnostic character, whereas others have a preventive or therapeutic effect. In healthcare, prior to introducing a new intervention or diagnostic threshold, professionals and policy makers have to consider what level of risk they would accept and what the expected effect of a newly introduced intervention is. Nonetheless, risk is an objective existence which can never be eliminated, is abrupt and often harmful with people suffering loss, may be uncertain in whether and when the event will happen, and is constantly developing with science and technology. Therefore, decisions are affected by estimating chances and taking the characteristics of these taken chances into account. The impact of that event can be either beneficial or detrimental, ranging from minor to major. However, risk is generally described as the combination of the linked likelihood of occurrence times the impact of a certain event.
