Main Healthcare APIs for Software Development: Benefits and Use Cases

Main Healthcare APIs for Software Development: Benefits and Use Cases

20 May 2022 • 16 min read

Imagine a world where all health apps, wearables, clinics, hospitals, private practices, and third-party vendors exchange data seamlessly. Using APIs in healthcare software development is just about that.

APIs significantly facilitate interoperability. You can think about it as a reflection of the medical industries' need to coordinate patient care across an ever-larger subset of players. There is some ability to do that now, but improvement is definitely needed.

A survey conducted by Black Book Research proves it. According to the report, more than 90% of US patients complain about the lack of data exchange. And two out of three respondents will consider changing their doctor or healthcare provider because of this.

But what exactly does API stand for in healthcare? Today, we’ll explain what these two concepts have to do with each other.

Let us start with an API, an application programming interface. It is a set of procedures and functions that allow the creation of applications that access the data or features of an app, operating service, or another service that is separate from it.

Using APIs, the healthcare providers can transfer data between EHR/EMR, informational systems, networks, healthcare applications, and devices, managing it effectively and combining it in one place. Saying simply, APIs in the healthcare industry, at its core, is all about the sending of information from one system to another.

Suppose your healthcare provider can input your information into a unified hospital database with health APIs. This way, all the data on your health record would be in one place, along with information about other patients. It is just what we did in our HIPAA Telmed application. It’s only one example, though; there are many more.

So, let’s look at APIs in more detail. Based on our experience, we will tell you about the most common APIs use cases and types, the challenges of their integration, and even more.

Share Medical Data Efficiently

APIs are all about fast and seamless data exchange. The patient can easily view all his medical records, share them with the doctor and receive medical care as quickly as possible. It is made possible by simplified solutions for managing private medical information.

Promote Innovation in Medicine

The quality and accuracy of medicine are founded primarily on the evidence base. APIs help build this base by making it easier to access patient data. In this way, companies can cooperate and make significant breakthroughs in the medical field.

Get the Best Treatment Results

APIs allow you to connect multiple systems. It, in turn, will enable the doctor to get a complete picture of his patient’s condition. Then the physician will be able to make more accurate treatment regimens, which will result in better treatment results.

Healthcare APIs Use Cases

We’ve learned about the benefits of using APIs for healthcare application development. But where exactly can you apply these technologies? Let us clarify.

Bridging the Gap Between Doctors and Patients

If you are:

  • A healthcare software provider (or own a healthcare organization) seeking to enable mobile and web diagnostic tools for your users
  • A research institution looking for new ways to connect with doctors and patients
  • A healthcare practitioner or hospital aiming to provide faster and real-time patient data or health records

In all of the above scenarios, medical APIs would help.

Just consider the next case of using API in the medical system. Persons with diabetes need to record their blood sugar levels, while the doctors need to control that and adjust the treatment accordingly.

A health API would facilitate the management and recording of physician-reported data. In easier words, the data on patients’ health records collected with, for example, IoT devices, can instantly be reflected in doctors’ dashboards.

Then based on that, the doctors can adjust to treatment that is instantly reflected in the diabetes platform for patients and saved in the physician’s system. In such a way, decision-makers can cut overhead costs and improve the efficiency of the treatment where APIs are involved.

Integrating Healthcare Operations

Another application of API in healthcare is a clinical API a hospital could develop for employees’ use. For instance, it could better predict the staff’s requirements and improve data management. It would reduce overtime costs and better serve patients.

Clinical API could also facilitate record sharing with other hospitals and medical offices. It would lessen the possibility of medical errors when hospital staff is focused on patient care instead of paperwork. Both time and money could be saved.

Providing Data Integration

Patients always want to have as much control over their health data as possible. APIs help make that a reality. They let patients provide health records to new facilities without making phone calls to receptionists.

Patients can leverage all the advantages of health fitness trackers and other smart devices since an API could connect such devices with an EHR system. It will assist doctors with diagnosis and treatment, which is a win-win for patients and doctors both.

Mobile Health

mHealth apps are becoming more common among users. For example, the number of such app downloads in the United States jumped by 30% at the beginning of the pandemic in 2020.

But what do APIs have to do with this? These tools enable smooth sharing of patient data via mobile devices, virtual appointment booking, video visits of doctors, and more.

Patient Insurance Management

You can connect your product’s APIs with insurance companies. Thus, these organizations would be able to determine the patient’s coverage for medication or a specific procedure almost instantaneously.

Of course, these are not all the medical APIs use cases. There is much more. To showcase you that, here is an illustration of some other medical system parties who can benefit from data exchange and management with APIs:

Types of Healthcare APIs

The APIs in a marketplace can be considered products if their consumption patterns warrant such a designation. In healthcare, common patterns might include finances and billing, scheduling, patient registration, ancillary, clinical, public health, and IoT.

Here are the main types of APIs for healthcare software development:

Registration API

The purpose of the registration APIs is to handle the registration functions involved with many EMR/EHR systems. By utilizing these registration APIs, engineers develop easy-to-use interfaces for patients. Then these can be integrated with various EMR systems to manage patient-specific data exchanges.

Scheduling API

Patients love the ability to schedule doctor appointments within the app. For this purpose, you could also use the scheduling API to integrate the appointment booking feature, send reminders, synchronize with other calendars, or check for open appointment slots. You could update, cancel, or reschedule appointments, again saving the need to make a phone call.

Financial API

Financial APIs for hospitals help manage money transactions between different healthcare providers and other parties like insurance agencies, pharmacies, etc. These APIs can be narrowed down into different categories. Some of those might be billing APIs or claims APIs.

Integrated this technology into your system or app, the doctors can automate payment posting, e.g., eBilling, or generate and send prescriptions to patients or insurance agencies.

It has become a must-have feature for mHealth apps that allows patients to pay with smartphones. Samely, this is a very convenient function for insurance and other medical parties. All of these become much easier where APIs are used.

Hospital Management API

Hospital management APIs can handle any clinical data exchange through EHR/EMR systems of different standards. Perhaps you have a mature API platform capable of data format transformations. It would connect to multiple systems and provide data feeds whenever a consumer made such requests.

These systems would include data streams like treatment plans, patient medication data, immunization details, and detailed family medical history. The physician looks at this data and makes decisions about the patient’s treatment.

By using clinical API, data is more secure and readily accessible. If a speedy decision is needed about an ailing patient, this will allow consulting doctors to make it.

Ancillary API

Ancillary APIs can integrate into one place information stored in the systems separated from core medical functions. Those might include radiology, nutrition, pharmacy, laboratory, telemedicine platforms, etc.

For example, this API application might be helpful when hospitals need to exchange data with external pharmacies regarding prescriptions and refill requests.

A medical API might also help in laboratory result data exchanges with different information systems or managing dietary orders with an external nutrition system. It is particularly helpful in an era where diabetes is on the rise.

Public Health API

Public health APIs can exchange reportable clinical data to the public, professional, federal registries, or research organizations. It can be used to track public health in the case of a threat, like the ongoing Covid-19 pandemic. These APIs also enable easy data exchanges for public health surveillance like EHR systems.

Challenges of APIs Integrations in Medical Apps

With advancements in technology, healthcare environments consist of a complicated mix of systems, databases, devices, processes, and applications. These serve physicians and patients, and there are always organizational challenges on how to combine and store all that data securely. So let’s look at the pitfalls of APIs Integrations in healthcare applications.

Privacy, Security, and Legacy Concerns

Medicine depends a lot on medical regulations. It’s no surprise as every person as a patient wants their data, e.g., personal health information (PHI), to be kept secure and private.

For that purpose, many have their own set of legal regulations regarding protecting medical data: HIPAA in the US, GDPR in Europe, PIPEDA in Canada, and DPA in the UK. All that has slowed down the growth of health APIs as they need to meet the requirements of these regulations.

Hopefully, most medical APIs provide safe data storage and exchange between all systems and networks with such technologies as encrypted protocol usage, blockchain, advanced authentication, and system access controls.

Technical Barriers

Many medical organizations are faced with the lack of technological resources, development standards, and low scalability of medical software. All of this slows down healthcare interoperability and affects the treatment quality of these healthcare providers.

Moreover, some healthcare providers use outdated software that does not support API integration. As a result, they keep exchanging data manually.

Financial Concerns

These issues stem from a lack of financial resources in the healthcare system. Another reason is the low awareness that investments in healthcare interoperability improve the quality of medical services.

For sure, the costs of medical software development or implementing and optimizing current software require a lot of resources. But it’s a long-term investment for making healthcare systems much better.

Lack of IT Usability

An additional challenge in API integration into healthcare systems is the lack of full documentation and practical tools for developers’ testing, designing, and monitoring.

In such cases, it’s often challenging for healthcare providers to integrate API with their own development resources. The solutions for that might be the API dev community that provides feedback and insight into features or using external developers with already proven experience.
