Dyspnea and Delirium at the End of Life

Risk Factors and Antipsychotic Usage Patterns Associated With Terminal Delirium in a Veteran Long-Term Care Hospice Population

Background

The development of delirium is very common in terminally ill patients. However, risk factors for terminal delirium in the veteran population are poorly identified. The purpose of this study was to (1) Identify risk factors for terminal delirium in a US Department of Veterans Affairs inpatient hospice population; (2) Assess usage patterns of antipsychotics for treatment of terminal delirium; and (3) Describe nursing assessment, nonpharmacologic interventions, and documentation of terminal delirium.

Methods

This was a retrospective case-control study of veterans who expired while admitted into hospice care at a long-term care hospice unit during the period of October 1, 2013 to September 30, 2015. Veterans' medical records were reviewed for the 2 weeks prior to the recorded death.

Results

Of 307 veterans admitted for hospice care, 67.4% required antipsychotics in the last 2 weeks of life for the treatment of terminal delirium. The average number of antipsychotic doses given was 14.9 doses per patient. The risk factors that were identified included the use of steroids, opioids, or anticholinergics; Vietnam-era veterans with liver disease; veterans with cancer and a comorbid mental health disorder; and veterans with a history of drug and/or alcohol abuse.

Conclusions

More than half of veterans admitted for hospice care experienced terminal delirium requiring treatment with antipsychotics. The identification of veterans most likely to develop terminal delirium will allow for early nonpharmacologic interventions and potentially decrease the need for treatment with antipsychotic medications.

Evaluating the Pharmacological Management of Terminal Delirium in Imminently Dying Patients With and Without the Comfort Measure Order Set

Terminal delirium is a distressing irreversible process that occurs frequently in the dying phase, often misdiagnosed and undertreated. A previous study in our organization revealed that terminal delirium was a poorly managed symptom at end of life. Pharmacological options are available in an existing order set to manage this symptom. The management plans of 41 patients identified as having terminal delirium were further evaluated. Elements extracted included medications prescribed to manage terminal delirium, whether medication changes occurred, and whether they were administered and effective. Patients with the order set were more comfortable as compared with the group without. Both groups had several changes made by the palliative care team. Nurses did not administer prescribed as-needed medication to more than one-third of patients. Modifications will be made to the existing order set, and additional education for staff will be organized.
