Achieving Health care Interoperability through Cloud-based Data Integration

In the healthcare industry, the data captured from the devices will be in a different format and standard. Though there are networks for exchanging health information, interoperability, governance, and data adjustment create difficulties. Health analytics analyses data to derive insights, identify trends, and enhance healthcare quality.

Global health data combines information from several sources to evaluate health trends, results, and the success of healthcare initiatives. It includes information about the patient’s medical records and diagnosis.

Here are some key areas to focus on in healthcare data:

  • A lack of standardized interfaces and protocols constrains exchanging capabilities.
  • Medical equipment utilizes exclusive data forms and protocols for communication, especially EHR from different healthcare devices.
  • The level of setting initiatives varies between vendors, nations, and regions, which might result in discrepancies in medical procedures and data interchange.

Business Challenges

To ensure patients’ data portability and safety, standardization is essential and needed since the healthcare industry utilizes many electronic devices for data capture.

The lack of interoperability across various healthcare systems and devices is one of the significant challenges. Healthcare equipment and systems might interpret the data differently, which could result in discrepancies. Complex integration interfaces, challenges in connecting to different networks, and concerns with the compatibility of devices across versions are critical for the HC Domain. Data exchange between devices and healthcare providers is another challenge. Porting patients’ data across vendors is very much required for all operational changes.

Azure FHIR enables easy interoperability and integration with healthcare systems.

It allows data exchange among healthcare providers and applications, making it easier for them to make better decisions based on the reports and information.

FHIR (Fast healthcare interoperability resource)  

In Azure, the FHIR is important in exchanging electrical healthcare data in a standardized structure. Each resource will be created for each domain, for example, patient demography, patient observation, clinical documents, etc. Each resource will have a standardized format to capture the data. The FHIR search API is a powerful search mechanism to retrieve specific information about the resources based on the particular specifications we need. If the base resource does not define the data, the extension will help include custom data. Here are the key aspects of Azure FHIR:

Data Storage:  

For the storage of FHIR data, Azure FHIR offers a fully controlled, flexible, and reliable solution. Azure provides the managed services to store and access the data.
Azure uses Blob Storage and Data Lake Storage.

FHIR APIs and Services:

A group of RESTful APIs (application programming interfaces) that adhere to the FHIR protocol are made available by Azure FHIR. These APIs allow programmers to handle medical records and clinical information, interface with FHIR resources, and help retrieve, update, and delete records based on requirements.

 Scalability and performance:

Azure FHIR uses the Azure cloud platform’s scalability and performance features. Even during times of high demand, it can manage enormous quantities of medical data, maintain rapid exchange rates, and offer quick access to FHIR services.


In FHIR, many more specifications are involved in structuring the data from the electronic device. For example, if the patient is under observation for an allergy or MRI scan, the data will also be in an image format with documentation. In this case, sending only the patient observations to the application devices will not be sufficient. It also requires patient information to map this. As we discussed earlier, each domain will have different resources. To solve this problem, the FHIR BUNDLE is needed. It helps exchange data from multiple sources to the application devices or the web server.

There are four types involved in the FHIR bundle,

  1. 1. Transaction
  2. 2. Messages
  3. 3. History
  4. 4. Documents

Here, the transaction type is used to create, update, and delete resources as a part of a single-unit transaction. It works on collecting requests from each resource and submitting them to the FHIR server. For each help, a separate request should be added. If any one of the requests fails while advancing to the FHIR server, the whole thing will fail. There is no partial result or success in the transaction-type FHIR bundle.

The Azure API for the FHIR resources has AAD (Azure Active Directory), which helps with authentication for the user. The FHIR resource can be written in any programming language, such as Java, Python, etc. The resources will be created in JSON or XML format, but the standard should be followed while creating the resources.


DICOM (Digital Imaging and Communications in Medicine) helps convert the various types of image data, such as MRIs, CT scans, and X-rays, into meaningful data. For example, it details the parameters, patient demography, etc. It is crucial for the consistency and interoperability of the exchange of medical data and images. There will be a standard format achieved here for the observations. It will also support better treatment planning.

ImagingStudy FHIR:  

FHIR has an ImagingStudy resource type, which helps exchange the data from the image to any other application device. There will be more series elements and instances associated with this imaging study. The standard is constructed with the identifiers for the image before it is published. Then, the ImagingStudy resource type is created, and the request can be made to get the response from the server. The endpoint from the server will be the URL. This URL will help get DICOM information about the study. The “study” will have the UID (unique identifier) and modality. Each study will have a “series,” and it will have more details in it, for example, the body part where it affects. There are instances where I will be giving in-depth information.


To summarize this study, FHIR facilitates interoperability by offering a standardized framework for exchanging medical data. Using bundles helps guarantee that relevant resources are gathered together, improving data management and system interaction.

The FHIR resources with bundles help exchange health care data from multiple resources, enable effective querying and searching, facilitate thorough data exchange, and improve data integrity. Data integrity is enhanced by employing transaction types in the FHIR bundle. ImageStudy resources in FHIR support interoperability, enable thorough imaging data transmission, improve care coordination, optimize data administration, provide easy connection with other healthcare resources, and encourage research and analytics. These benefits help healthcare providers offer better patient care, more effective processes, and better use of medical imaging data.
