What Are APIs and Why Are They Essential for Healthcare Businesses?

IBM describes the API function as: "An intermediary layer that processes data transfers between systems letting companies open their application data and functionality to internal departments within their companies, as well as external third-party developers."

As the data sharing regulations of the 21st Century Cures Act encourage standardization and proliferation throughout the healthcare ecosystem, APIs will play a significant role in health IT interoperability now and in the future.

With the use of a standardized implementation model of the application programming interface, a health system may be operating one EHR in the office, another in the hospital, and the anesthesiology department may be utilizing a third, and before the patient even leaves the OR, their essential clinical data is exchanged over an extensive number of disconnected data silos. APIs could propel the industry to unprecedented levels of consumption and interoperability by establishing a single data exchange and communication point.

The Benefits and Challenges of APIs in Healthcare

challenges of solving complex clinical problems with APIs in healthcare. Can they improve medicaid services?

API provides several advantages to healthcare organizations, payers, and health insurance portability businesses. It also has limitations and issues when it comes to system integration. This section will educate you about the benefits and drawbacks of healthcare APIs.

Benefits of APIs in Healthcare

APIs are quite useful in any industry. However, there are some special benefits when it comes to healthcare.

  • Boosting the development process:

    Because using APIs speeds up the development process without affecting the end-user experience, APIs contribute to rapid, creative development in the healthcare industry.

  • Integration and personalization:

    By data exchange with a third-party app, businesses can better understand what other applications patients use to track their health, how users manage this demographic data, and what worries them about their health, allowing them to design better services based on this knowledge.

  • Enhanced Patient Engagement:

    By offering a complete picture of a patient's medical data, the Business API enables healthcare organizations to deliver personalized and proactive treatment, resulting in higher patient engagement and satisfaction.

  • Workflow Automation:

    It streamlines healthcare operations by automating procedures, lowering administrative responsibilities, and assuring seamless collaboration across healthcare teams.

  • Scalability and adaptability:

    The Health Cloud Business API is extremely scalable, allowing healthcare organizations to support expansion while adapting to changing needs. Its adaptability allows for modification to meet unique business requirements.

  • Capabilities for Healthcare Data Integration:

    API interfaces smoothly with other products and third-party systems, allowing interoperability and centralizing data exchange for quick decision-making.

  • Compliance and Security:

    Health Cloud complies with industry standards and laws, protecting data privacy and Security, including HIPAA and GDPR compliance.

Challenges of APIs in Healthcare

Despite all the benefits, there can be some limitations to the API introduction. Here are the main ones:

  • Budget:

    Creating a corporate healthcare solution always costs money. The establishment of the API raises the total even further.

  • Security and privacy:

    There are more requirements for safeguarding medical information. For instance, access via APIs can be authorized and authenticated using third-party apps.

  • The culture and workflow:

    The process of data exchange starts when the patient starts creating data and receiving access to specific data sources. Certain firms exhibit caution over the inflow of data.

  • Learning Curve:

    Healthcare organizations may need to devote time and money to employee training to fully utilize the platform's features after adopting the Health Cloud Business API.

  • Complexity of Customization:

    Advanced modifications may require Salesforce development and management knowledge to ensure a successful deployment.

Data Integration and Interoperability

There is a substantial difference between healthcare data Integration and Interoperability. Integration refers to the method of connecting applications to access data sources from one system. However, integration involves a third party such as "middleware" that translates the data and makes it "work" for the receiving system. Integration doesn't provide a direct path for information to get from point A to point B.

Whereas, Healthcare Interoperability cannot only share information but also interpret incoming data and present it as it was received, preserving its original context.

For instance, when a hospital's IT system and the electronic health record (EHR) of a primary care physician (PCP) are integrated, healthcare interoperability is accomplished.

There are several approaches to accommodate this data flow. These consist of:

  • Interaction of clinical data via healthcare data integration services.
  • A care team member using a different software system to access another directly
  • Systems inform one another of certain occurrences or activities.

Fast healthcare interoperability resources, which support linking systems and exchanging information, are made possible via healthcare data integration.

Integration of apis in healthcare for next generation data exchange and robust interoperability standards can achieve the following

The 2023 State of Interoperability is a comprehensive analysis produced in January by Health Gorilla, a software platform promoting interoperability. Its contents provide in-depth analyses from over 130 senior healthcare decision-makers, and it was determined that data sharing and quality issues still exist.

Statistics from the report further solidify the need for comprehensive integration and interoperability:

  • 60% of health systems receive duplicate, incomplete, and junk data
  • 69% of health organizations receive incomplete data
  • 69% of digital health executives receive incomplete data
  • 32% of diagnostic labs do not contribute at all to a health information exchange (HIE); when they do, 76% participate only regionally
  • 40% of surveyed EHR vendors are aware of a potential need to join a Qualified Health Information Network (QHIN) but are not prioritizing this action

Integration and interoperability are not fully adopted, mainly because of concerns about patient privacy, data security, and challenges in implementing new technologies.

How Do Healthcare API Solutions Improve Patient Outcomes?

Healthcare APIs improve patient outcomes by increasing cooperation between healthcare professionals and patients, which leads to a better user experience, more care, and feasibility in accessing medical data.

Healthcare organizations produce an incredible volume of patient data daily, including test results, vital signs, medical histories, and prescription data. APIs can lessen test duplication while enhancing clinical decision-making as they make it simpler for healthcare practitioners to access and exchange patient data. Patients with complicated medical histories or chronic ailments should pay particular attention to this as they may find it difficult to track their medical information and frequently see many healthcare providers.

Patients are unwilling to participate in their care passively. APIs are essential in enabling patients to engage in more active participation. By granting patients access to medical records, they can dispel the mystery surrounding the healthcare system. Patients are more likely to be more proactive in managing their health when they are better informed about the process. Patient access to their medical data provided by healthcare organizations is an important part of data integration strategies.

Research indicates that 98% of medical providers concur that health information technology is essential to delivering an exceptional patient experience.

The Future of API Interoperability in Healthcare

The 21st Century Cures Act data exchange rules, which promote standardization and growth among healthcare interoperability businesses, indicate that healthcare APIs have a promising future. Anticipate an increase in the use of APIs in the healthcare industry in the next few years to link providers to more comprehensive data, enhance patient outcomes, and provide the general public with better access to their medical information.

The healthcare business cannot optimize interoperability unless it adheres to data standards. Standardized data results in a linked data collection that is simple to process and utilize. This data should give the sector new levels of insight and opportunity into the requirements of patients, providers, and payers, allowing it to make better-educated decisions. API data in healthcare can then guide the industry in standardizing new data points and influencing regulations that govern and control the healthcare business.

Business cases are driving the future of APIs in healthcare for next-generation data interchange. While FHIR is intended to strive towards a completely backward-compatible standard, the industry is pressuring healthcare interoperability organizations to adopt a standardized implementation strategy.

What Is A Better Choice? Ready-Made Solution Or Custom Integration?

What offers more robust interoperability standards? ready-made api framework or customized api in healthcare

The main goal of healthcare API is to transmit and connect data at a single point.

Healthcare organizations have two options: choose a ready-made solution or develop a customized one with the help of an experienced healthcare software developer. Both choices have advantages and disadvantages.

A ready-made solution is cost-effective and takes less time than custom software development. They come with comprehensive features tested and refined by the software provider. Ready-made software is typically sold on a subscription or licensing basis, which helps businesses avoid upfront development costs associated with custom solutions. BUT!

In healthcare, client data safety and privacy are the biggest priorities. Any negligence can have a massive financial impact on the organization and the patient and damage the reputation. For this sole purpose and to comply with healthcare regulations, a business should consider building a custom API rather than using a third-party ready-made API.

Custom APIs provide businesses with opportunities for innovation and scalability. It also helps them cater to the changing needs of patients without halting the system. In ready-made API, a company has limited access to make the changes.

Custom API is a better option because companies can make alterations to integrate with any system or cloud computing, whereas it can not be done in ready-made API.


A new generation of creative direct-to-consumer companies is revolutionizing the healthcare and population health technology industries due to the increased desire for long-term, preventative treatment outside hospitals.

The developments in the finance and consumer tech sectors serve as inspiration for a large number of developers nowadays. A new wave of healthcare IT businesses is emerging, driven by APIs and eager to innovate in response to the growing need for patient-centered virtual care.

Healthcare APIs are the next big thing in the software development industry.
