The Fast Healthcare Interoperability – FHIR Patient resource is a standardized format for representing and exchanging patient-related information in electronic health records (EHRs) and healthcare systems. FHIR is a healthcare interoperability standard developed by HL7 (Health Level Seven International), a global authority in healthcare standards.
Introduction
The Patient resource in FHIR provides a structured representation of an individual or a subject of care within a healthcare system. It includes a variety of information about the patient, such as their demographics, medical history, allergies, medications, immunizations, and other relevant clinical and administrative data.
The FHIR Patient resource follows a modular approach, allowing different healthcare systems to exchange patient information in a consistent and standardized manner. It is designed to be easily accessible, flexible, and extensible, supporting the integration of patient data from various sources and enabling interoperability between different healthcare systems.
The Patient resource in FHIR is based on a set of standardized data elements called resources. These resources can be combined and linked to represent complex healthcare scenarios and workflows. The FHIR Patient resource serves as a central hub for patient information, enabling healthcare providers, systems, and applications to access and share patient data efficiently and securely.
By using the FHIR Patient resource, healthcare organizations can improve data exchange, care coordination, and interoperability across different healthcare systems, which ultimately enhances the quality of patient care and facilitates better healthcare outcomes.
Structure of FHIR Patient Resource
The FHIR Patient resource in JSON format follows a specific structure defined by the FHIR specification. Other formats like XML and Turtle exist, but here we will talk about JSON. Here’s an example of how a Patient resource might look in JSON format:
{
"resourceType": "Patient",
"id": "example",
"identifier": [
{
"system": "http://example.com/identifiers",
"value": "12345"
}
],
"name": [
{
"use": "official",
"family": "Smith",
"given": ["John"]
}
],
"gender": "male",
"birthDate": "1970-01-01",
"address": [
{
"use": "home",
"line": ["123 Main St"],
"city": "Anytown",
"state": "NY",
"postalCode": "12345",
"country": "USA"
}
],
"telecom": [
{
"system": "phone",
"value": "555-123-4567"
},
{
"system": "email",
"value": "john.smith@example.com"
}
],
"maritalStatus": {
"coding": [
{
"system": "http://terminology.hl7.org/CodeSystem/v3-MaritalStatus",
"code": "M",
"display": "Married"
}
]
},
"active": true
}
In this example, the Patient resource contains various fields representing different aspects of the patient’s information:
resourceType: indicates that this resource is of type “Patient.”id: uniquely identifies the patient resource within the system.identifier: provides one or more identifiers associated with the patient.name: represents the patient’s name, including given name(s) and family name.gender: specifies the patient’s gender.birthDate: indicates the patient’s date of birth.address: represents the patient’s address, including street, city, state, postal code, and country.telecom: includes contact information for the patient, such as phone numbers and email addresses.maritalStatus: describes the patient’s marital status using standardized coding systems.active: indicates whether the patient’s record is currently active.
This is a simplified example, and there are many more fields and options available in the Patient resource to capture additional patient information, such as medical history, allergies, and medications. The actual structure of the resource can vary depending on the specific use case and the needs of the healthcare system implementing FHIR. The complete patient resource structure can be found here.
Commonly used fields
The FHIR Patient resource includes various fields to capture patient information comprehensively. While the specific fields used can vary based on the requirements of the healthcare system or application, here are some commonly used fields in the Patient resource:
identifier: Represents one or more identifiers associated with the patient, such as medical record numbers, social security numbers, or health insurance numbers.name: Specifies the patient’s name, including given name(s) and family name. It may also include prefixes or suffixes.gender: Indicates the patient’s gender, such as male, female, other, or unknown.birthDate: Represents the patient’s date of birth.address: Describes the patient’s address details, including street, city, state, postal code, and country.telecom: Includes contact information for the patient, such as phone numbers, email addresses, or other communication details.maritalStatus: Represents the patient’s marital status using standardized coding systems.communication: Specifies the patient’s preferred language for communication and other languages they understand or use.generalPractitioner: Indicates the primary care physician or general practitioner responsible for the patient’s care.managingOrganization: Specifies the healthcare organization or facility that manages the patient’s care.extension: Allows for additional custom or specific data elements to be included, extending the Patient resource as needed.
These are some commonly used fields, but it’s important to note that the FHIR specification provides many more fields and options to represent various aspects of patient information, such as demographics, clinical data, medical history, allergies, medications, and more. The selection and usage of fields depend on the specific use case and the requirements of the healthcare system or application implementing FHIR.
Sample use cases where patient resources are utilized
A sample use case where the FHIR Patient resource can be utilized is in the context of an electronic health record (EHR) system. The EHR system aims to maintain and manage patient information for healthcare providers, allowing them to access and update patient data efficiently. The Patient resource can be employed to represent and exchange patient-related information within the EHR system. Here’s a simplified scenario:
- Creation of a New Patient Record:
- When a new patient visits a healthcare provider, the EHR system can create a new Patient resource to capture their information.
- The Patient resource would include details such as the patient’s demographics, contact information, insurance details, and other relevant data.
- This resource serves as a central repository for the patient’s information within the EHR system.
- Retrieving Patient Information:
- Healthcare providers can retrieve patient information by querying the EHR system using the Patient resource.
- The resource allows retrieving details such as the patient’s medical history, allergies, current medications, lab results, and past procedures.
- This enables healthcare providers to have a comprehensive view of the patient’s health information when providing care.
- Updating Patient Information:
- When the patient’s information changes or new data becomes available, the EHR system can update the Patient resource accordingly.
- For example, if the patient moves to a new address, the address field in the Patient resource can be updated to reflect the change.
- Healthcare providers can also add new information such as diagnoses, treatments, or immunizations to the Patient resource.
- Interoperability with Other Systems:
- The Patient resource in FHIR facilitates interoperability by providing a standardized format for exchanging patient information.
- The EHR system can share the Patient resource with other healthcare systems or providers securely, allowing for continuity of care.
- For example, when a patient is referred to a specialist, the EHR system can share the relevant patient information using the Patient resource, ensuring that the specialist has access to the necessary data.
Overall, the use of the Patient resource in an EHR system helps streamline patient data management, improves care coordination, and enables interoperability among different healthcare systems and provider
