The SMART Launch Sequence: A Step-by-Step Breakdown
The SMART launch sequence is a crucial process that ensures a secure and seamless connection between your SMART on FHIR application and a patient’s EHRs. Each step in this sequence plays a vital role in establishing a robust and interoperable link, facilitating efficient data exchange, and promoting interoperability in healthcare systems.
Let’s break down each step for a clearer understanding.
Step 1 – Application Launch
The application launch is triggered when users interact with your application by clicking a link or button within the Electronic Health Record (EHR) system. This initiation prompts the user’s browser to be redirected to a predefined URL supplied by the EHR system. This redirection mechanism is a fundamental aspect of the secure and standardized approach adopted by SMART on FHIR, facilitating a controlled and authenticated transition between the EHR environment and your application.
Step 2 – Request Access
The URL generated from the EHR system directs users to the authorization server. This authorization server plays a vital role by presenting a login screen where users are prompted to confirm their identity. Through this secure authentication process, users can grant explicit access permissions to your application, ensuring that only authorized individuals can interact with and retrieve data from the patient’s Electronic Health Record (EHR) system.
This step establishes a critical layer of security, safeguarding sensitive health information throughout the integration process.
Step 3 – Receive Tokens
After a successful login, the authorization server redirects the user’s browser to your application. Your application receives an authorization code—a temporary key along with the redirection. The authorization code is crucial, enabling your application to obtain more permanent access tokens securely.
These tokens facilitate ongoing interactions between your SMART on the FHIR application and the patient’s Electronic Health Record (EHR) system, ensuring continued secure access to relevant health data.
Step 4 – Client Request to Access or Modify Clinical Data
In the fourth step of the SMART launch sequence, your application utilizes the authorization code acquired and establishes a connection with the EHR’s token endpoint. Your application sends a request through this connection that includes the authorization code and other pertinent information.
This step is crucial as it serves as the mechanism for exchanging the temporary authorization code for more durable access and refresh tokens. These tokens help your application securely access or modify clinical data within the patient’s EHR, maintaining the integrity and confidentiality of health information.
Step 5 – Validate Token
In the further stage, the token endpoint receives the request from your application and performs a crucial verification process by validating the authorization code with the authorization server. Upon successful validation, the token endpoint generates two necessary tokens for your application:
Access Token: This token is a temporary permission slip granting your application the specific authorization to access defined patient data within the Electronic Health Record (EHR) system based on the user’s consent.
Refresh Token: This token is designed to obtain new access tokens when the current one expires. It plays a crucial role in ensuring continuous and uninterrupted access to patient data, enhancing the longevity and sustainability of your application’s integration with the EHR system.
Step 6 – Response of the Server to Access or Change Clinical Data
In the sixth step of the SMART launch sequence, your application, now equipped with the access token from the previous stage, is ready to request the Fast Healthcare Interoperability Resources (FHIR) API within the Electronic Health Record (EHR) system.
These requests can serve two primary purposes:
Retrieve Specific Patient Data: Your application can request specific patient information, such as allergies or medications, based on the authorized scopes granted during the initial authentication process.
Modify Data within the EHR System: Your application can request to modify data within the EHR system with appropriate permissions.
The EHR FHIR server validates the received access token before responding to your application’s requests. If the access token is valid, the server fulfills the request by delivering the requested data or confirming the successful modification. This secure exchange ensures that your application only accesses authorized data, safeguarding patient privacy and maintaining the integrity of the clinical information.
