Iatrogenic delirium on symptom-triggered alcohol withdrawal protocol

Area of Science:

• Medical Science
• Clinical Practice
• Pharmacology

Background:

• Alcohol withdrawal syndrome (AWS) management often involves symptom-triggered therapy.
• This approach utilizes instruments like the Clinical Institute for Withdrawal Assessment of Alcohol, Revised (CIWA-Ar) to guide benzodiazepine administration.
• While effective in reducing dosage and duration, CIWA-Ar has limitations, particularly with non-verbal patients or those in confusional states.

Purpose of the Study:

• To highlight delirium as a potential complication of symptom-triggered therapy in alcohol withdrawal.
• To explore alternative treatment strategies for managing alcohol withdrawal and associated delirium.
• To emphasize the importance of considering differential diagnoses beyond standard AWS assessment.

Main Methods:

• Case report of a 47-year-old male admitted for overdose.
• Patient developed worsening delirium while on the CIWA-Ar protocol.
• Review of limitations of symptom-triggered therapy and alternative management options.

Main Results:

• Symptom-triggered therapy, while reducing benzodiazepine use, may obscure underlying delirium.
• Over-reliance on CIWA-Ar can lead to overlooking alternative etiologies for patient symptoms.
• The case demonstrates a scenario where CIWA-Ar protocol may be insufficient for complex presentations.

Conclusions:

• Providers must consider alternative assessment tools and treatment modalities for alcohol withdrawal.
• Objective scales, fixed benzodiazepine tapers, and antiepileptic medications are potential alternatives.
• A comprehensive approach is necessary to avoid misdiagnosis and ensure appropriate patient care.
