Nutrition Intake observables

Current template, still in process is located here: A nutritional intake (observable entity) - v1.0

Example:

Questions:

A few examples being requested, unclear on how/if we can model:

  • Fasting pattern in one calendar day (observable entity) - also requesting same for "one calendar week", "one calendar month", "one calendar year".

Estimated fruit servings in 24 hours (observable entity)| - in number per day, what to do with servings:

Substance questions

  • 784184006 |Estimated oral fluid intake in 24 hours (observable entity)| - no substance of "fluid"?
  • Estimated total intake of fluid from food (observable entity) - "fluid from food"?
  • Intake of enriched food (observable entity) also requesting same for "fortified food", "special dietary food", "medical food", "processed food", "quick service food", "self prepared food", "prepared food"
  • Measured number of snacks in 24 hours (observable entity) - "snacks" is there an international definition?
  • 100% fruit juice - concentration - (https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfcfr/CFRSearch.cfm?fr=101.30)

  1. On our discussion, the approach of describing just the observed mass with a 24 process duration is simpler and would seem more faithful to the real world in these mass/24h concepts.  It would avoid the 'rate' ambiguity as well as the specimen detail in outputs.  It would fit both intake and output.  People would be at liberty to transform the values into a mass/minute avg rate or whatever, as they wish; the opposite direction might be more dubious, but if a 12 hour measurement is done and doubled then doesn't that indicate a calculation technique should be represented?

  2. We think that 33463005 |Liquid substance (substance)| might help for the question above and would like some input.

  3. Hi Donna,

    33463005 |Liquid substance (substance)| refers to a state of matter. Considering its children, which requires some clean up, I doubt it is a suitable concept for defining nutrition concepts referring to edible liquids.

    Thanks,

    1. Farzaneh,

      Thank you for taking a look at this. Yes, we recognize that this is a state of matter and may seem an odd fit except that is what liquids are. Our concept not only includes edible liquids, but also liquids via enteral feeding tube and Intravenous fluids 118431008 |Fluid for intravenous administration (substance)|, which also uses this concept as a parent. Any suggestions are welcome!

  4. HI Donna and Farzaneh,

    My suggestion (and also after consultation in pharmacy) would be to use the product hierarchy rather than substance. As Farzaneh says the substance hierarchy is the state of matter.

    Substances can be used to describe the ingredients of a product ...

    Here is the difference

    • Substance| represents general substances, the chemical constituents of pharmaceutical/biological products, body substances, dietary substances and diagnostic substances (e.g. |methane|, |insulin|, |albumin|).
    • |Pharmaceutical/biologic product| represents drug products (e.g. |amoxicillin 250mg capsule|, |paracetamol + codeine tablet|). It also includes nutritional products..

    Hope this helps

    Debbie 

  5. I agree, there are a number of places we would prefer to use a product (e.g. 412413001 |Infant formula (product)|)but we are currently prohibited from doing so outside of the substance project.  Toni Morrison Farzaneh Ashrafi I am not sure when that will change, in the interim with only "substance" available we would need to leave these concepts primitive.  I would like a process for tracking concepts awaiting the availability of products.

    Regards, 

    Penni

  6. Hi Penni Hernandez Farzaneh Ashrafi

    I'd suggest tracking the primitive concepts via CRS; there are already a number of similar instances where we are awaiting the availability of modeling with a product concept logged there. You can assign the requests to me. It looks like there is work needed in the dietary product and foods area that is beyond the work planned for 2020-Jan. (which is focused primarily on medicinal products and therapeutic roles).

    Thanks,

    Toni
