OK, so the patient is drunk. Some then might say that the blood alcohol level is obtained to determine the level of intoxication. I honestly believe that the term “blood alcohol level” almost implies a correlation between intoxication and the number (level). We know that the effects of alcohol are very idiosyncratic; everyone experiences a different response based on a multitude of factors, including their level of exposure, comorbidities, previous exposure, etc. Historically, we believed that the number could be applied to a formula to predict clearance. This has been disproved. Furthermore, Roberts and Dollard published an article in 2010, and the conclusions are words to live by: “Attempting to relate observed signs of alcohol intoxication or impairment, or to evaluate sobriety, by quantifying blood alcohol levels can be misleading, if not impossible.”9

ACEP Now: Vol 34 – No 01– January 2015The only reliable test for determining the level, or degree, of intoxication is the physical examination. In other words, if you can carry on a normal conversation, your judgment and insight are reasonable, and your motor function is not impaired (eg, ambulation without difficulty, no slurred speech), you’re not clinically intoxicated. Having all of the providers agree to this assessment in the medical record is key to avoiding discrepancies. However, adding an unnecessary blood alcohol level into the diagnostic picture only serves to cast doubt on your clinical determination that the patient wasn’t impaired. Impairment is the key, not a specific number. Remember, the legal level of intoxication (different from state to state) relates to a person’s ability to legally operate a motor vehicle in that state. This arbitrary level has no clinical basis and should not be applied in the world of clinical medicine.
Unnecessary blood alcohol levels in the medical record may cast doubt on your clinical assessment and may obviate you to observe your patients for extended periods of time while waiting for them to achieve a level for safe motor vehicle operation in your state, a number irrelevant to the clinical management of your patient.

Derek McCalmontDr. Klauer incorrectly states that the level of blood alcohol for legal intoxication varies from state to state. Laws and penalties vary but the level of .08 is universal across all 50 states.
At what point does Dr. Klauer propose discharge for intoxicated patients without family or friends to assume care in the absence of a blood alcohol level?
