Things We Do For No Reason: Use of Antipsychotic Medications in Patients with Delirium

In addition, hospitalists should implement the core elements of the nursing delirium protocol from the Hospital Elder Life Program (https://www.hospitalelderlifeprogram.org/). The program focuses on orientation, hydration, mobility, sensory aids, and an environment conducive to sleep.¹⁸ When not representing an acute threat to the patient or staff, hospitalists should manage transient agitation from blood draws or vital sign checks by having staff members deescalate and re-approach the intervention later. While multicomponent nonpharmacologic interventions have more robust evidence for prevention of delirium than for treatment, they are low risk and still recommended for the patient with established delirium.^19,20

A delirious patient picking at PIVs should prompt clinicians to re-evaluate the need for continued PIV access. If still necessary, experience suggests that PIVs can be protected with a combination of well-taped gauze extending from wrist to shoulder with any attached tubing exiting out of reach behind the shoulder. Also “beneficial distraction” with a task or “activity vest” that consists of an apron with zips, ties, and buttons designed to provide harmless objects can occupy the patient’s hands.

The literature does not provide clear evidence for when the use of antipsychotics is warranted. Antipsychotics may have a role for patients who are having severe psychotic symptoms posing an acute safety risk. In those situations, the American Geriatrics Society recommends using the “lowest effective dose for the shortest possible duration to treat patients who are severely agitated or distressed, and are threatening substantial harm to self and/or others…only if behavioral interventions have failed or are not possible.”¹² In those patients who are having an acute myocardial infarction, consider atypical antipsychotics since haloperidol carries a small increased risk of mortality in that patient population.²¹

• Address underlying modifiable contributions to the delirium paying attention to medications, pain, electrolytes, ischemia, infection, alcohol withdrawal, and reducing invasive lines. Deprescribe sedative/hypnotic and anticholinergic medications.
• After addressing modifiable risk factors, attempt behavioral interventions for continuous problematic behaviors or symptoms of delirium.
• Reserve antipsychotics for cases where the patient poses an immediate danger of self-harm or harm to others. Treat for the shortest possible duration with the lowest effective dose of antipsychotic.

Returning to our case presentation, the hospitalist should not prescribe antipsychotic medications since there is no immediate risk of harm and antipsychotics do not treat hypoactive delirium. Delirium is a complex condition requiring a review of multifactorial causes. The hospitalist should investigate and address modifiable contributions. Furthermore, the hospitalist can make the PIV less accessible to deter the patient’s efforts to remove it and offer a distracting activity. Resolution of delirium, in all its forms, is still best achieved by treating the underlying etiology. The use of antipsychotics for treatment of patients with delirium in the absence of severe agitation and potential for self-harm or harm to others is not supported by the current body of literature as it is more likely to cause an adverse event than it is to improve the symptoms.
