FHIR_ (Fast Healthcare Interoperability Resources) is a specification for exchanging healthcare information electronically. It is designed to facilitate the exchange of data between different healthcare systems and applications, and is commonly used to build APIs (Application Programming Interfaces) for healthcare data. It is based on modern web technologies, and is designed to be easy to use and implement. It uses a modular approach, with a set of "resources" that represent different types of healthcare data (such as patients, observations, and diagnoses). These resources can be combined and extended as needed to support a wide range of healthcare use cases.
This "fhir.resources" package is powered by pydantic_ so faster in performance and optionally orjson
support has been included as a performance booster!
Obviously it is written in modern python and has data validation built-in.
It provides tools and classes for all of the FHIR Resources <https://www.hl7.org/fhir/resourcelist.html>
_ defined in the FHIR specification,
and allows you to create and manipulate FHIR resources in Python. You can then use these resources to build FHIR-based APIs or to work with FHIR data in other ways.
ORM <https://en.wikipedia.org/wiki/Object-relational_mapping>
_.Experimental XML and YAML serialization and deserialization supports. See [Advanced Usages] section!
FHIR® (Release R5, version 5.0.0) is available as default. Also previous versions are available as Python sub-package
(each release name string becomes sub-package name, i.e R4B
).
From fhir.resources
version 7.0.0; there is no FHIR R4
instead of R4B
is available as sub-package.
Available Previous Versions:
R4B
(4.3.0)STU3
(3.0.2)DSTU2
(1.0.2) [see issue#13 <https://github.com/nazrulworld/fhir.resources/issues/13>
_][don't have full tests coverage]Just a simple pip install fhir.resources
or easy_install fhir.resources
is enough. But if you want development
version, just clone from https://github.com/nazrulworld/fhir.resources and pip install -e .[dev]
.
Example: 1: This example creates a new Organization resource with some of its attributes (id, active, name, address)::
>>> from fhir.resources.organization import Organization
>>> from fhir.resources.address import Address
>>> data = {
... "id": "f001",
... "active": True,
... "name": "Acme Corporation",
... "address": [{"country": "Switzerland"}]
... }
>>> org = Organization(**data)
>>> org.resource_type == "Organization"
True
>>> isinstance(org.address[0], Address)
True
>>> org.address[0].country == "Switzerland"
True
>>> org.dict()['active'] is True
True
Example: 2: This example creates a new Organization resource from json string::
>>> from fhir.resources.organization import Organization
>>> from fhir.resources.address import Address
>>> json_str = '''{"resourceType": "Organization",
... "id": "f001",
... "active": True,
... "name": "Acme Corporation",
... "address": [{"country": "Switzerland"}]
... }'''
>>> org = Organization.parse_raw(json_str)
>>> isinstance(org.address[0], Address)
True
>>> org.address[0].country == "Switzerland"
True
>>> org.dict()['active'] is True
True
Example: 3: This example creates a new Patient resource from json object(py dict)::
>>> from fhir.resources.patient import Patient
>>> from fhir.resources.humanname import HumanName
>>> from datetime import date
>>> json_obj = {"resourceType": "Patient",
... "id": "p001",
... "active": True,
... "name": [
... {"text": "Adam Smith"}
... ],
... "birthDate": "1985-06-12"
... }
>>> pat = Patient.parse_obj(json_obj)
>>> isinstance(pat.name[0], HumanName)
True
>>> pat.birthDate == date(year=1985, month=6, day=12)
True
>>> pat.active is True
True
Example: 4: This example creates a new Patient resource from json file::
>>> from fhir.resources.patient import Patient
>>> import os
>>> import pathlib
>>> filename = pathlib.Path("foo/bar.json")
>>> pat = Patient.parse_file(filename)
>>> pat.resource_type == "Patient"
True
Example: 5: This example creates a new Organization resource in python way::
>>> from fhir.resources.organization import Organization
>>> from fhir.resources.address import Address
>>> json_obj = {"resourceType": "Organization",
... "id": "f001",
... "active": True,
... "name": "Acme Corporation",
... "address": [{"country": "Switzerland"}]
... }
>>> org = Organization.construct()
>>> org.id = "f001"
>>> org.active = True
>>> org.name = "Acme Corporation"
>>> org.address = list()
>>> address = Address.construct()
>>> address.country = "Switzerland"
>>> org.address.append(address)
>>> org.dict() == json_obj
True
.. note::
Please note that due to the way the validation works, you will run into issues if you are using construct()
to create
resources that have more than one mandatory field. See this comment in issue#56 <https://github.com/nazrulworld/fhir.resources/issues/56#issuecomment-784520234>
_ for details.
Example: 4: This example creates a new Organization resource using Resource Factory Function::
>>> from fhir.resources import construct_fhir_element
>>> json_dict = {"resourceType": "Organization",
... "id": "mmanu",
... "active": True,
... "name": "Acme Corporation",
... "address": [{"country": "Switzerland"}]
... }
>>> org = construct_fhir_element('Organization', json_dict)
>>> org.address[0].country == "Switzerland"
True
>>> org.dict()['active'] is True
True
Example: 5: Auto validation while providing wrong datatype::
>>> try:
... org = Organization({"id": "fmk", "address": ["i am wrong type"]})
... raise AssertionError("Code should not come here")
... except ValueError:
... pass
FHIR Comments (JSON)
It is possible to add comments inside json like xml, but need to follow some convention, what is suggested by `Grahame Grieve <http://www.healthintersections.com.au/?p=2569>`_;
is implemented here.
Also it is possible to generate json string output without comments.
Examples::
>>> observation_str = b"""{
... "resourceType": "Observation",
... "id": "f001",
... "fhir_comments": [

Special Case: Missing data
In some cases <https://www.hl7.org/fhir/extensibility.html#Special-Case>
_, implementers might
find that they do not have appropriate data for an element with minimum cardinality = 1.
In this case, the element must be present, but unless the resource or a profile on it has made the
actual value of the primitive data type mandatory, it is possible to provide an extension that
explains why the primitive value is not present.
Example (required intent
element is missing but still valid because of extension)::

Custom Validators
``fhir.resources`` is providing the extensive API to create and attach custom validator into any model. See more `about root validator <https://pydantic-docs.helpmanual.io/usage/validators/#root-validators>`_
Some convention you have to follow though, while creating a root validator.
1. Number of arguments are fixed, as well as names are also. i.e ``(cls, values)``.
2. Should return ``values``, unless any exception need to be raised.
3. Validator should be attached only one time for individual Model. Update [from now, it's not possible to attach multiple time same name validator on same class]
Example 1: Validator for Patient::
from typing import Dict
from fhir.resources.patient import Patient
import datetime
def validate_birthdate(cls, values: Dict):
if not values:
return values
if "birthDate" not in values:
raise ValueError("Patient's ``birthDate`` is required.")
minimum_date = datetime.date(2002, 1, 1)
if values["birthDate"] > minimum_date:
raise ValueError("Minimum 18 years patient is allowed to use this system.")
return values
# we want this validator to execute after data evaluating by individual field validators.
Patient.add_root_validator(validate_gender, pre=False)
Example 2: Validator for Patient from Validator Class::
from typing import Dict
from fhir.resources.patient import Patient
import datetime
class MyValidator:
@classmethod
def validate_birthdate(cls, values: Dict):
if not values:
return values
if "birthDate" not in values:
raise ValueError("Patient's ``birthDate`` is required.")
minimum_date = datetime.date(2002, 1, 1)
if values["birthDate"] > minimum_date:
raise ValueError("Minimum 18 years patient is allowed to use this system.")
return values
# we want this validator to execute after data evaluating by individual field validators.
Patient.add_root_validator(MyValidator.validate_gender, pre=False)
**important notes** It is possible add root validator into any base class like ``DomainResource``.
In this case you have to make sure root validator is attached before any import of derived class, other
than validator will not trigger for successor class (if imported before) by nature.
ENUM Validator
~~~~~~~~~~~~~~
``fhir.resources`` is providing API for enum constraint for each field (where applicable), but it-self doesn't
enforce enum based validation! see `discussion here <https://github.com/nazrulworld/fhir.resources/issues/23>`_.
If you want to enforce enum constraint, you have to create a validator for that.
Example: Gender Enum::
from typing import Dict
from fhir.resources.patient import Patient
def validate_gender(cls, values: Dict):
if not values:
return values
enums = cls.__fields__["gender"].field_info.extra["enum_values"]
if "gender" in values and values["gender"] not in enums:
raise ValueError("write your message")
return values
Patient.add_root_validator(validate_gender, pre=True)
Reference Validator
fhir.resources
is also providing enum like list of permitted resource types through field property enum_reference_types
.
You can get that list by following above (Enum) approaches resource_types = cls.__fields__["managingOrganization"].field_info.extra["enum_reference_types"]
Usages of orjson
orjson_ is one of the fastest Python library for JSON and is more correct than the standard json library (according to their docs).
Good news is that ``fhir.resource`` has an extensive support for orjson_ and it's too easy to enable it automatically. What you need to do, just make orjson_ as your project dependency!
pydantic_ Field Type Support
All available fhir resources (types) can be use as pydantic_'s Field's value types. See issue#46 Support for FastAPI pydantic response models <https://github.com/nazrulworld/fhir.resources/issues/46>
_.
The module fhirtypes.py
contains all fhir resources related types and should trigger validator automatically.
Resource.id aka fhirtypes.Id
constraint extensibility
There are a lots of discussion here here i.) https://bit.ly/360HksL ii.) https://bit.ly/3o1fZgl about the length of ``Resource.Id``'s value.
Based on those discussions, we recommend that keep your ``Resource.Id`` size within 64 letters (for the seek of intercompatibility with third party system), but we are also providing freedom
about the length of Id, in respect with others opinion that 64 chr length is not sufficient. ``fhirtypes.Id.configure_constraints()``
is offering to customize as your own requirement.
Examples::
>>> from fhir.resources.fhirtypes import Id
>>> Id.configure_constraints(min_length=16, max_length=128)
Note: when you will change that behaviour, that would impact into your whole project.
XML Supports
~~~~~~~~~~~~
Along side with JSON string export, it is possible to export as XML string!
Before using this feature, make sure associated dependent library is installed. Use ``fhir.resources[xml]`` or ``fhir.resources[all]`` as
your project requirements.
**XML schema validator!**
It is possible to provide custom xmlparser, during load from file or string, meaning that you can validate
data against FHIR xml schema(and/or your custom schema).
Example-1 Export::
>>> from fhir.resources.patient import Patient
>>> data = {"active": True, "gender": "male", "birthDate": "2000-09-18", "name": [{"text": "Primal Kons"}]}
>>> patient_obj = Patient(**data)
>>> xml_str = patient_obj.xml(pretty_print=True)
>>> print(xml_str)
<?xml version='1.0' encoding='utf-8'?>
<Patient xmlns="http://hl7.org/fhir">
<active value="true"/>
<name>
<text value="Primal Kons"/>
</name>
<gender value="male"/>
<birthDate value="2000-09-18"/>
</Patient>
Example-2 Import from string::
>>> from fhir.resources.patient import Patient
>>> data = {"active": True, "gender": "male", "birthDate": "2000-09-18", "name": [{"text": "Primal Kons"}]}
>>> patient_obj = Patient(**data)
>>> xml_str = patient_obj.xml(pretty_print=True)
>>> print(xml_str)
>>> data = b"""<?xml version='1.0' encoding='utf-8'?>
... <Patient xmlns="http://hl7.org/fhir">
... <active value="true"/>
... <name>
... <text value="Primal Kons"/>
... </name>
... <gender value="male"/>
... <birthDate value="2000-09-18"/>
... </Patient>"""
>>> patient = Patient.parse_raw(data, content_type="text/xml")
>>> print(patient.json(indent=2))
{
"resourceType": "Patient",
"active": true,
"name": [
{
"text": "Primal Kons",
"family": "Kons",
"given": [
"Primal"
]
}
],
"gender": "male",
"birthDate": "2000-09-18"
}
>>> with xml parser
>>> import lxml
>>> schema = lxml.etree.XMLSchema(file=str(FHIR_XSD_DIR / "patient.xsd"))
>>> xmlparser = lxml.etree.XMLParser(schema=schema)
>>> patient2 = Patient.parse_raw(data, content_type="text/xml", xmlparser=xmlparser)
>>> patient2 == patient
True
Example-3 Import from file::
>>> patient3 = Patient.parse_file("Patient.xml")
>>> patient3 == patient and patient3 == patient2
True
**XML FAQ**
- Although generated XML is validated against ``FHIR/patient.xsd`` and ``FHIR/observation.xsd`` in tests, but we suggest you check output of your production data.
- Comment feature is included, but we recommend you check in your complex usages.
YAML Supports
~~~~~~~~~~~~~
Although there is no official support for YAML documented in FHIR specification, but as an experimental feature, we add this support.
Now it is possible export/import YAML strings.
Before using this feature, make sure associated dependent library is installed. Use ``fhir.resources[yaml]`` or ``fhir.resources[all]`` as
your project requirements.
Example-1 Export::
>>> from fhir.resources.patient import Patient
>>> data = {"active": True, "gender": "male", "birthDate": "2000-09-18", "name": [{"text": "Primal Kons", "family": "Kons", "given": ["Primal"]}]}
>>> patient_obj = Patient(**data)
>>> yml_str = patient_obj.yaml(indent=True)
>>> print(yml_str)
resourceType: Patient
active: true
name:
- text: Primal Kons
family: Kons
given:
- Primal
gender: male
birthDate: 2000-09-18
Example-2 Import from YAML string::
>>> from fhir.resources.patient import Patient
>>> data = b"""
... resourceType: Patient
... active: true
... name:
... - text: Primal Kons
... family: Kons
... given:
... - Primal
... gender: male
... birthDate: 2000-09-18
... """
>>> patient_obj = Patient.parse_raw(data, content_type="text/yaml")
>>> json_str = patient_obj.json(indent=True)
>>> print(json_str)
{
"resourceType": "Patient",
"active": true,
"name": [
{
"text": "Primal Kons",
"family": "Kons",
"given": [
"Primal"
]
}
],
"gender": "male",
"birthDate": "2000-09-18"
}
Example-3 Import from YAML file::
>>> from fhir.resources.patient import Patient
>>> patient_obj = Patient.parse_file("Patient.yml")
>>> json_str = patient_obj.json(indent=True)
>>> print(json_str)
{
"resourceType": "Patient",
"active": true,
"name": [
{
"text": "Primal Kons",
"family": "Kons",
"given": [
"Primal"
]
}
],
"gender": "male",
"birthDate": "2000-09-18"
}
**YAML FAQ**
- We are using https://pyyaml.org/ PyYAML library, for serialization/deserialization but if we find more faster library, we could use that. you are welcome to provide us your suggestion.
- YAML based comments is not supported yet, instead json comments syntax is used! Of course this comment feature is in our todo list.
Allow Empty String
~~~~~~~~~~~~~~~~~~
Although this is not good practice to allow empty string value against FHIR primitive data type ``String``. But
we in real life scenario, is it unavoidable sometimes.
Examples::
Place this code inside your __init__.py module or any place, just to make sure that this fragment of codes is runtime executed.
>>> from fhir.resources.fhirtypes import String
>>> String.configure_empty_str(allow=True)
FHIR release R4B over R4
------------------------
FHIR release R4B is coming with not that much changes over the release of R4. So we decided not to create separate sub-package for R4 like STU3, instead there just overlaps on existing R4. This also means that in future, when we will work on R5; there will be sub-package for R4B and no R4.
We suggest you to try make a plan to be upgraded to R4B. Here you could find related information dealing-strategy-R4-R4B_.
You could find full discussion here https://github.com/nazrulworld/fhir.resources/discussions/116
Migration (from ``6.X.X`` to ``7.0.X``)
---------------------------------------
First of all, you have to correct all imports path, if you wish to keep continue using FHIR release R4B or R4, as those resources
are moved under sub-package named ``R4B``. Then if you wish to use current ``R5`` release,
read carefully the following documents.
1. See the full changes history -> https://build.fhir.org/history.html
2. See complete lists of differences between R5 and R4B -> https://hl7.org/fhir/R5/diff.html
3. If you are planning to migrate direct from the release ``R4``,
then it is important to look at the differences between R4B and R4 here -> https://hl7.org/fhir/R4B/diff.html
Migration (from later than ``6.X.X``)
-------------------------------------
This migration guide states some underlying changes of ``API`` and replacement, those are commonly used from later than ``6.X.X`` version.
``fhir.resources.fhirelementfactory.FHIRElementFactory::instantiate``
Replacement: fhir.resources.construct_fhir_element
First parameter value is same as previous, the Resource name.
Second parameter is more flexible than previous! it is possible to provide not only json dict
but also
json string or json file path.
No third parameter, what was in previous version.
fhir.resources.fhirabstractbase.FHIRAbstractBase::__init__
**Replacement:** ``fhir.resources.fhirabstractmodel.FHIRAbstractModel::parse_obj<classmethod>``
- First parameter value is same as previous, json dict.
- No second parameter, what was in previous version.
``fhir.resources.fhirabstractbase.FHIRAbstractBase::as_json``
Replacement: fhir.resources.fhirabstractmodel.FHIRAbstractModel::dict
Output are almost same previous, but there has some difference in case of some date type, for example py date, datetime, Decimal are in object representation.
It is possible to use fhir.resources.fhirabstractmodel.FHIRAbstractModel::json
as replacement, when
json string is required (so not need further, json dumps from dict)
Note:
All resources/classes are derived from fhir.resources.fhirabstractmodel.FHIRAbstractModel
what was previously
from fhir.resources.fhirabstractbase.FHIRAbstractBase
.
Starting from version 5.0.0
we are following our own release policy and we although follow Semantic Versioning scheme like FHIR® version.
Unlike previous statement (bellow), releasing now is not dependent on FHIR®.
removed statement
This package is following `FHIR® release and versioning policy <https://www.hl7.org/fhir/versions.html>`_, for example say, FHIR releases next version 4.0.1,
we also release same version here.
All FHIR® Resources (python classes) are generated using fhir-parser_ which is forked from https://github.com/smart-on-fhir/fhir-parser.git.
This package skeleton was created with Cookiecutter_ and the audreyr/cookiecutter-pypackage
