For practicality and simplicity we divide proven or potential risk factors among three categories 1 host characteristics 2 features of the acute illness and 3 environmental or iatrogenic factors Table 1 .27a The accumulation of risk factors likely portends development of delirium.

Critically ill patients easily have at least three risk factors. In fact in a study of 53 consecutive medical ICU patients Ely et al discovered that each patient had a mean standard deviation of 11 4 delirium risk factors with a range of three to The accumulation of risk factors in critically ill patients undoubtedly contributes to a high prevalence of delirium. Perhaps the most universal and potentially modifiable risk factor among critically ill patients is exposure to psychoactive .
