In their review of surveillance methods for alcohol withdrawal syndrome (AWS) in the surgical ICU, the authors state that both the CIWA-Ar and BAWS scales “are not validated in critically ill, medically complex, or postoperative patients.” They correctly point out that one of the limitations of the CIWA-Ar is that most items require the patient to answer questions. They recommend the mMINDS tool because it “does not require the patient to answer questions.”
First, I would like to point out that the BAWS has been studied in critically ill patients – we published a report on 279 admissions to intensive care units at two hospitals where the BAWS was used to guide treatment (1). Second, while both the BAWS and mMINDS rely more on observation that patient report, both include assessment of orientation and hallucinations (plus delusions with mMINDS), which requires a patient to answer questions.
