Letter to the editor, RE: The Hack Index

Abstract

We read Hack et al's recent work with great interest.(1) While we applaud the effort to objectively quantify degree of impairment of intoxicated patients using the Hack Impairment Index (HII) in the emergency department, there are some notable limitations to this study which require further discussion.The HII score had a strong agreement with nurses’ clinical assessments of intoxication. Despite the p value being impressive, their value for agreement was not indicated in the results.
