In medical terms, ETOH stands for ethylalcohol. When found noted on a medical record, it indicates the presence of alcohol on the breath of a patient.
Hospital staff and emergency responders use many abbreviations on medical documents to help record, communicate and track a patient's status. When an emergency responder or emergency room nurse treats a patient who smells of alcohol, ETOH is noted on the medical record. Whether the patient admits alcohol use or not, this communication ensures that doctors and nurses are aware of its presence so they can factor that into their treatment plan for the patient.
