Dose

Originally proposed at Wikidata:Property proposal/Natural science

Not done

Description	MISSING
Represents	dose (Q473420)
Data type	Quantity
Allowed units	Milligrams, micrograms, international units
Example	aciclovir (Q147101) → 800 milligram route of administration (P636) = oral administration (Q285166) event interval (P2257) = 1 day
Source	en:Dose (biochemistry)
Planned use	Plan is to use as a qualifier for the price of different medications
Robot and gadget jobs	Eventually

Motivation

Doses of medications will be required for listing prices or defining how a medication is usually taken.

For example the typical dose of amoxicillin is 500 mg po TID

The wholesale price of 500 mg of amoxicillin is 0.063 USD as of July 17th, 2019 in the United States.[1]

Right now we are using "quantity" but when one adds 400 mg it gives a warning Doc James (talk · contribs · email) 04:33, 17 July 2019 (UTC)[reply]

Support The nearest current properties are measured physical quantity (P111) and quantity (P1114). Unfortunately, P111 has a datatype of "Item" and we need a "Quantity" datatype. P1114 has its qualifiers constrained to start time (P580), end time (P582), point in time (P585), statement is subject of (P805), sourcing circumstances (P1480), excluding (P1011), and including (P1012) and has a item of property constraint (P2305) set to no value, neither of which seem to align with what we need for a dose. Therefore it seems to me that the concept of a dose is sufficiently unique to be worth its own property where we can set more suitable constraints that won't interfere with the current properties. --RexxS (talk) 13:53, 17 July 2019 (UTC)[reply]
Support. Interesting property. However, its description should be further detailed. --Csisc (talk) 16:39, 17 July 2019 (UTC)[reply]

@Doc James: Please provide a description for the property and examples.
I'm a bit weary about the potential of people adding a dose to the chemical compounds. Inutively it seems to me like only packaged drugs have a dosis and the dosis isn't a property of the underlying chemical substances. ChristianKl ❪✉❫ 14:06, 17 July 2019 (UTC)[reply]
- @ChristianKl: Q147101 look at price, currently quantity is being used Doc James (talk · contribs · email) (if I write on your page reply on mine) 16:24, 17 July 2019 (UTC)[reply]
Question Should this property also address dose units for other than chemicals, such as for Q186161 ionizing radiation? LeadSongDog (talk) 17:25, 17 July 2019 (UTC)[reply]
- User:LeadSongDog you mean in a medication related context? Doc James (talk · contribs · email) 21:38, 18 July 2019 (UTC)[reply]
  - No, not just in medication-related context: In a ionizing radiation safety context, workers wear dosimetry badges to track occupational exposure; In semiconductors, defined quantities of neutrons cause defined p-type doping effects; In a photochemistry context, defined quantities of light are used to power many reactions (e.g. photosynthesis, epoxy polymerization, cross-linking of synthetic rubbers, etc.); In food safety, defined radiation doses can be used to sterile-package uncooked foods as an alternative to Pasteurization.

    - If you think that this would be useful for that purpose sure... Doc James (talk · contribs · email) 15:52, 30 July 2019 (UTC)[reply]
Oppose Isn't this what defined daily dose (P4250) is for? There are also some related properties like acceptable daily intake (P2542) that cover other aspects of this. In any case the current proposal is too ill-defined to be suitable here. ArthurPSmith (talk) 18:47, 17 July 2019 (UTC)[reply]
Oh, hang on, you just want a property that works like "quantity" but allows units/non-integer values? It looks like we don't have something for that at all - how about calling this "amount" then? ArthurPSmith (talk) 18:53, 17 July 2019 (UTC)[reply]
User:ArthurPSmith yes perfectly happy with calling it "amount". What we are looking for is a dosage which is an amount for a medication. DDD is a specific type of amount as is ADI. Doc James (talk · contribs · email) 20:56, 18 July 2019 (UTC)[reply]
@Doc James: We might want to try a completely new proposal for that - this one seems a little too tied to the medical context; we should also come up with some other examples where it would be useful, I'm sure they exist! ArthurPSmith (talk) 21:02, 18 July 2019 (UTC)[reply]
User:ArthurPSmith Actually it might be best to tie this specifically to medications. We could remove a constraint from quantity (P1114) but that could have a lot of negative effects. Doc James (talk · contribs · email) 21:11, 18 July 2019 (UTC)[reply]
I checked defined daily dose (P4250) and acceptable daily intake (P2542) to see how the proposal modeled examples for those properties. There is hardly any modeling. I tried to do some modeling here in this edit. Before it referred to an item, and now there is still that item linked but I also tried to move the administration and event frequencies here for discussion. To talk about a dose, we need an amount, a time period, and an administration route, right? Is it still worthwhile to describe a dose with less information than that? What other information is also helpful?
I am unsure with Arthur about overlap with those existing properties, which may be sufficient. Blue Rasberry (talk) 19:42, 17 July 2019 (UTC)[reply]
- We may also need formulation, like is it extended release, oral dissolving tablet, liquid, tablet, capsule, etc. Doc James (talk · contribs · email) 21:01, 18 July 2019 (UTC)[reply]
Support It is needed for the particular usage of medecine. Antoine2711 (talk) 21:11, 18 July 2019 (UTC)[reply]
Oppose Use "quantity", and fix the constraints. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 10:01, 23 August 2019 (UTC)[reply]
- User talk:Pigsonthewing who exactly is going to fix the constraint? I am not clear why it is there to tell you the truth. Doc James (talk · contribs · email) 11:17, 29 August 2019 (UTC)[reply]
  - Have suggested that here.[2] Doc James (talk · contribs · email) 14:05, 17 November 2019 (UTC)[reply]
