What is the abbreviation for alcohol used in medical notes?

The abbreviation for alcohol in medical notes is EtOH. This term comes from the chemical name for ethanol, which is the type of alcohol that is typically consumed. In medical contexts, using the abbreviation EtOH helps to clearly refer to alcohol without confusion, particularly when discussing alcohol use, abuse, or related health issues.

The other choices represent different medical abbreviations: DM stands for diabetes mellitus, F/U denotes follow-up, and DVT refers to deep vein thrombosis. Each of these has its own specific medical meaning, but none relate to alcohol or its notation in medical records. Therefore, EtOH is the appropriate and standardized abbreviation used by healthcare professionals.
