Delirium

This chapter provides an overview of delirium, differentiating among hyperactive, hypoactive, and mixed subtypes. Delirium is a common, serious medical problem that is underrecognized by healthcare providers. Evidence suggests that frequent assessment of patients can result in increased recognition of delirium, which will allow for earlier intervention. Limited data are available on effective interventions for delirium once it begins; however, proactive prevention strategies have been successful. Various screening tools are recommended to identify patients with delirium. The multiple predisposing and precipitating factors that can complicate determining the cause are explored. There is a review of the assessment and interventions for delirium management and prevention protocols that target its risk factors, as well as a brief discussion of the principles of pharmacological management and previously cited recommendations. Education of staff, patients, and family members is vital.
