The purpose of this paper is to illustrate delirium as a possible consequence of the application of symptom-triggered therapy for alcohol withdrawal and to explore alternative treatment modalities. In the management of alcohol withdrawal syndrome, symptom-triggered therapy directs nursing staff to regularly assess patients using standardized instruments, such as the Clinical Institute for Withdrawal Assessment of Alcohol, Revised (CIWA-Ar), and administer benzodiazepines at symptom severity thresholds. Symptom-triggered therapy has been shown to lower total benzodiazepine dosage and treatment duration relative to fixed dosage tapers (Daeppen et al., 2002). However, CIWA-Ar has important limitations. Because of its reliance on patient reporting, it is inappropriate for nonverbal patients, non-English speakers (in the absence of readily available translators) and patients in confusional states including delirium and psychosis. Importantly, it also relies on the appropriate selection of patients and considering alternate etiologies for signs and symptoms also associated with alcohol withdrawal.

The authors report a case of a 47-year-old male admitted for cardiac arrest because of benzodiazepine and alcohol overdose who developed worsening delirium on CIWA-Ar protocol.

While symptom-triggered therapy through instruments such as the CIWA-Ar protocol has shown to lower total benzodiazepine dosage and treatment duration in patients in alcohol withdrawal, over-reliance on such tools may also lead providers to overlook other causes of delirium.

This case illustrates the necessity for providers to consider using other available assessment and treatment options including objective alcohol withdrawal scales, fixed benzodiazepine dosage tapers and even antiepileptic medications in select patients.
