I know this was a topic that was looked at a few years (2021-01-27 Editorial Advisory Group Conference call - SNOMED CT Editorial Advisory Group - SNOMED Confluence) and "resolved" but I'm not convinced the outcome is correct.
Specifically, that Intoxication (disorder) IS A Poisoning (disorder).
The current text definition "Diminished control of mental or physical functioning caused by a substance." Indicates this about "being under the influence" not simply "toxic affects". (Though I think "altered" might be better than "diminished"). Also, is there an actual difference between Intoxication (disorder) and Acute intoxication (disorder)
If there are chronic/persistent issues - that's something much more serious. I see this
82782008|Alcohol poisoning| and 25702006|Alcohol intoxication| are two quite different things for an ED presentation.
Somebody with Alcohol poisoning is going to be intoxicated, but cases of Alcohol intoxication are not poisonings. - suggesting the current modelling is around the wrong way.
If it's regarded from the very generous view of "any alcohol is poisonous" then - even without taking a Paracelsus view of toxicity - many/most medicines, especially those with side-effects could be considered.
Then there's sedatives (and as mentioned in the minutes "do not operate machinery").
I think this is where Overdose (disorder) comes in - where it is a poisoning caused by something that can be "taken" in some acceptable/recommended dose.
However, 82782008|Alcohol poisoning| is not currently a subtype of |Overdose (disorder)|
Here's the definition from ICD-10 for Acute intoxication
A condition that follows the administration of a psychoactive substance resulting in
disturbances in level of consciousness, cognition, perception, affect or behaviour, or
other psycho-physiological functions and responses. The disturbances are directly
related to the acute pharmacological effects of the substance and resolve with time,
with complete recovery, except where tissue damage or other complications have
arisen. Complications may include trauma, inhalation of vomitus, delirium, coma,
convulsions, and other medical complications. The nature of these complications
depends on the pharmacological class of substance and mode of administration.
Acute drunkenness (in alcoholism)
- ‘Bad trips’ (drugs)
- Drunkenness NOS
- Pathological intoxication
- Trance and possession disorders in psychoactive substance intoxication
Excl.: intoxication meaning poisoning
