Creating Patient and Patient Observations by using iris-fhir-client application

Hi Community,

This article will demonstrate how to create Patient and Patient Observation Resources  by using iris-fhir-client application.

I recommend to read my  first article  about this app and watch Youtube Video  before continue

so let's start

1-Create Patient Resource

below CreatePatient() function of dc.FhirClient can be use to Create Patient Resource

ClassMethod CreatePatient(givenName As %String, familyName As %String, birthDate As %String,gender As %String)

function requires giveName,failyName,birthDate and gender to create Patient Resource
 below command will create Patient

do ##class(dc.FhirClient).CreatePatient("PatientGN","PatientFN","2000-06-01","male")

Below is the python function in irisfhirclient.py file which will create patient

import json
from fhirpy import SyncFHIRClient
from tabulate import tabulate
from fhirpy.base.searchset import Raw
import requests

def CreatePatient(givenName,familyName,birthDate,gender,url,api_key):
    headers = {"Content-Type":contentType,"x-api-key":api_key}
    client = SyncFHIRClient(url = url, extra_headers=headers)
    
    patient = client.resource("Patient")
    patient['name'] = [
        {
            'given': [givenName],
            'family': familyName,
            'use': 'official'
        }
    ]

    patient['birthDate'] = birthDate
    patient['gender'] = gender
    try:
        patient.save()
    except Exception as e:
        print("Error while creating Patient:" +str(e))       
        return
    print("Patient Created Successfully")    

 

2- Create Patient Observation Resource
 

Let us create Observation against our newly created Patient Resource

below CreateObservatoin() function of dc.FhirClient can be use to Create Patient Observatoins
ClassMethod CreateObservation(patientId As %String, loincCode As %String, ObrCategory As %String, ObrValue As %Integer, ObrUOM As %String, effectiveDate As %String)

Parametres

  • patientId is the Id of Patient
  • LioncCode is Lionc Code, Detail can be found here
  • ObrCategory is Observation Category, Detail can be found here
  • ObrValue is Observatoin Value
  • ObrUOM is Observation Unit
  • EffectiveDate

below command will create Patient Vital Sign Observation

do ##class(dc.FhirClient).CreateObservation("8111","8310-5","vital-signs",96.8,"degF","2022-01-22")

image

Let's List down patient observations

do ##class(dc.FhirClient).GetPatientResources("Observation","8111")

image

Below is the python function in irisfhirclient.py file which will create patient

import json
from fhirpy import SyncFHIRClient
from tabulate import tabulate
from fhirpy.base.searchset import Raw
import requests

#Function to create Patient Observation
def CreateObservation(patientId,loincCode,ObrCategory,ObrValue,ObrUOM,effectiveDate,url,api_key):
    headers = {"Content-Type":contentType,"x-api-key":api_key}
    client = SyncFHIRClient(url = url, extra_headers=headers)
    observation = client.resource(
    'Observation',
    status='preliminary',
    category=[{
        'coding': [{
            'system': 'http://hl7.org/fhir/observation-category',
            'code': ObrCategory
        }]
    }],
    code={
        'coding': [{
            'system': 'http://loinc.org',
            'code': loincCode
        }]
    })
    observation['effectiveDateTime'] = effectiveDate
       
    observation['valueQuantity'] = {
    'system': 'http://unitsofmeasure.org',
    'value': ObrValue,
    'code': ObrUOM
    }
    
    #find the patient
    patient = client.resources('Patient').search(_id=patientId).first()
    observation['subject'] = patient.to_reference()
    
    try:
        observation.save()
    except Exception as e:
        print("Error while creating observation :"+ str(e))       
        return
    print("Patient Observation Created Successfully")

That's it
