In my EMS reports,( and this is coming from a crosstrained Medic/LEO)
are worded like this:
The patient had an odor of an alcoholic beverage on or about their person. They had slurred speech, horizontal gaze nystagmus was present, and he/she had an unsteady gait. Their eyes were also noted to be red and glassy. Pt also appeared to be lacking fine motor control when asked to perform simple motor tasks. Pt did admit to drinking "at least 4 bud lite beers" over the course of the last 2 hours. Pt denies any previous or current medical conditions that could cause similar impairment. They also deny the use of illegal drugs, or other precription medications that would also cause such impairment.
The State Attorney's here LOVE me for this, because even though I cannot always go over to the LEO and tell them exactly what Ive written in my report, the SAO will subpoena my PCR, and when they read that statement, its a slam dunk as far as establishing that they did, in fact, appear to be under the influence of alcohol ( or whatever they took)
I DO NOT state they are drunk, or appear to be drunk or intoxicated.
YOU DO NOT WANT TO SAY "smell of alcohol" or ETOH. (Abbreviations are NOT A GOOD THING IN COURT, and bad practice in the current day and age of ePCR's when space is not an issue for the narrative, and you dont have to worry about poor penmanship.)
Alcohol does not have an odor, but beer does, mixed alcoholic drinks do. You DO NOT want to state they are drunk, as I said above, but you do want to clearly and carefully document ALL of your observations about the exam, the patient's behavior, and anything they say and do during your time with them, because the totality of the circumstances will point out loud and clear to a jury or a judge, or an attorney, that the suspect/patient did exhibit several signs consistent with alcohol or drug intoxication, and coupled with an admission of consumption of an intoxicating agent, its very easy to see the conclusion one would draw in the situation.
Id also like to point out that even in a situation where EMS will not be transporting the patient, a very very thorough examination and point of care diagnostic testing (blood glucose levels, 12 lead ekgs, Stroke assessment, cranial nerve exam, etc) is VERY IMPORTANT. Not only does it assure you that your patient is exhibiting the signs and symptoms of alcohol intoxication (or drug intoxication) but it also establishes redundancy and corroborates the LEO's DUI examination. On the other hand, if they are not drunk or under the influence of drugs, your thorough examination may be what helps the defense attorney prove that their client's innocence.
You also need to be impartial... and sometimes this can be very very hard, especially if you're doing your exam on a suspected DUI that just killed an entire family... but it is essential that you remain impartial, and do your job. Interjecting personal assumptions and opinions can cloud the PCR, and even allow the defense attorney to establish a pattern showing that you're biased toward or against a suspected DUI... and they can use that in future DUI's to help their client beat the charge. Just some food for thought.
This is the same advice given to the EMS crews by the State Attorney's Office, and the same advice given to LEO's during DUI training
and if you follow it correctly, and carefully, and choose your statements and words carefully, they are pretty darn near airtight.
Hope this helps.
