can some one help me, I need to find where in FHIR can i get Patient's BLOOD GROUP

It would be an Observation. Question for others - should we add this as a standardized vital sign?
Pascal Pfiffner (Feb 27 2017 at 10:59):
Interesting, has blood type been handled as an Observation generally or have people used an extension? It being a characteristic that doesn't change, like birthdate and gender, I would have expected it to live on Patient, maybe as a standardized extension.
I don't quite think of it as a vital sign, which usually are common measures of the body's current functioning. Not saying that Observation is wrong though, there are Profiles on Observation for things like gestational age at birth, which usually also doesn't change. :)

It not a vital sign is more like a patient characteristic like eye color.

we should keep medical concepts out of the Patient resource. It needs to be broadly communicated, so it should focus on describing the patient as an 'identity'. Identity is a sensitive enough concept, but to add medical concepts would make the Patient resource even harder to manage properly.

The blood group can change after getting a Bone Marrow Transplant. Gender can change over time as well.
Pascal Pfiffner (Feb 27 2017 at 15:48):
Agree John, I didn't mean to suggest it should live on Patient, just saying that this would be my immediate expectation as opposed to looking in vital signs.
Would it make sense to have patient characteristics profiles, a sister page to the Observation profiles? Those would capture things like blood type, gestational age at birth, Fitzpatrick skin type and other characteristics which only rarely change but don't live on Patient? Of course stuffing them into vital signs wouldn't be the end of the world.
Lloyd McKenzie (Feb 27 2017 at 16:36):
Seems reasonable to have a distinct category for those things where you'd expect there to generally only be "1" observation instance and the observation time doesn't much matter as opposed to vitals where there'll be lots of observations and the notion of trending, baseline and most recent are relevant.
Eric Haas (Feb 27 2017 at 16:36):
AS the vitals profile editor - I'm saying no stuffing more into that profile... I'd rather create a new profile
Lloyd McKenzie (Feb 27 2017 at 16:37):
Does this seem like the sort of thing where standardizing at an international level is reasonable?
Eric Haas (Feb 27 2017 at 16:39):
It will face the same resistance as vitals did.
Lloyd McKenzie (Feb 27 2017 at 16:43):
Sure. But do we think we can come up with a reasonable, commonly needed set of characteristics where the benefits of consistency would be worth dealing with that resistance?
Grahame Grieve (Feb 27 2017 at 20:06):
it would be good to try. but it will never be as tight as vitals.

Gender is a social construct and can change; however I don't think that biological (birth) sex can change over time, as could the person's blood type due to BMT.
Lloyd McKenzie (Mar 02 2017 at 05:17):
Birth sex can change if someone decides it was captured wrong. And of course there are multiple aspects of birth sex that can be captured. So it might be pretty rare to change, but "can't" is a word I use with great caution when it comes to healthcare data :) The key differentiator we care about here is that a given patient should, at a given point in time only have *one* value for each of these properties that is deemed to be correct/accurate. And there wouldn't be a notion of trending. (Which makes it quite different from vital signs.)
