How to query for Observations

Introduction

This sample will demonstrate how to issue a FHIR Query for Observations using the FHIR RESTful API and the SMART on FHIR JavaScript Client.

FHIR RESTful API

Query to find the patient demographics

Given a patient ID "BILIBABY", find the patient:

• https://api.logicahealth.org/hspcdemo/open/Patient/BILIBABY

Query to find the bilirubin observations

Find the observations for BILIBABY where the code is for Transcutaneous Bilirubin

• https://api.logicahealth.org/hspcdemo/open/Observation?patient=BILIBABY&code=58941-6

SMART on FHIR JavaScript Client

NOTE: This example is not following the SMART on FHIR launch specification.  In your code, you will not connect to an EHR this way, but will be given the serviceUrl and patient values from the launch request.  See Quick Start for details.
