Main healthcare APIs: Types, providers, and use cases

Written by Farah Amod | November 30, 2024

Over 90% of US patients are frustrated with the lack of data sharing between healthcare providers. Traditional methods like fax machines and phone calls are still widely used.

To fix this, new regulations require healthcare systems to use APIs (Application Programming Interfaces) for data exchange. APIs promise to transform healthcare by allowing different systems to connect smoothly, empowering patients to manage their health better.

 

API standards in healthcare

  • FHIR API: The Fast Healthcare Interoperability Resources (FHIR) standard, developed by HL7, provides the framework for the exchange of electronic health records (EHRs) through REST APIs. FHIR simplifies exchanging healthcare data by representing patient information as "resources" (e.g., lab results, medications, or conditions). This modular approach allows different healthcare systems to "talk" to each other in a standardized format. EHR vendors and hospitals adopting FHIR make it easier for developers to create health apps, improving patient care coordination and streamlining access to health data.
  • USCDI standard: The United States Core Data for Interoperability (USCDI) outlines the specific health data elements that must be exchanged using APIs. It covers clinical information such as allergies, medications, and lab results. The goal of the USCDI is to ensure that healthcare providers and patients have a consistent set of data accessible across platforms, improving care delivery and continuity.
  • Security and privacy standards: Since APIs involve sharing sensitive medical data, strong security measures must be in place. HIPAA (in the US) and GDPR (in Europe) govern the privacy and security of health information. API protocols include encryption and secure authentication mechanisms, ensuring only authorized users can access patient data. These security measures are needed to maintain patient trust and meet legal compliance.
  • SMART on FHIR: The SMART on FHIR framework builds on FHIR, enabling third-party developers to build health apps that can securely connect to EHRs. Using OAuth 2.0 authentication, SMART ensures that health apps can safely access a patient’s data with their consent, creating opportunities for personal health management tools that empower patients to monitor and manage their conditions outside the traditional healthcare setting.

EHR API providers

Electronic Health Record (EHR) APIs enable healthcare providers to access and exchange patient data easily. Major EHR vendors like Epic, Cerner, and Allscripts have developed APIs that improve data sharing and compliance with interoperability standards. These APIs support healthcare organizations in managing patient records, enhancing clinical workflows, and improving care coordination.

Public health and drug data APIs

Public health APIs provide access to health data and drug information. APIs like openFDA and RxNorm allow healthcare providers and researchers to access data on drugs, interactions, and recall. Public health authorities can also use these APIs for epidemiology studies, trend monitoring, and disease management strategies.

 

Clinical data management APIs

Clinical data management APIs assist healthcare providers in organizing and analyzing patient data for better care delivery. With the help of artificial intelligence (AI) and machine learning, these APIs—such as those offered by Amazon HealthLake and Google Cloud Healthcare—enable healthcare providers to uncover insights from vast clinical datasets, improving diagnosis, treatment, and operational efficiency.

Symptom checker and telehealth APIs

Symptom checker APIs, such as Infermedica or Mayo Clinic's solutions, enable healthcare platforms to provide patients with preliminary assessments and guidance based on reported symptoms. Additionally, telehealth APIs like those from DrChrono or Bluestream power remote healthcare services, allowing virtual consultations, scheduling, and secure communication between patients and providers.

 

Consolidated APIs

Consolidated APIs aggregate health data from various sources such as EHRs, wearable devices, and labs. These APIs provide a holistic view of a patient's health, facilitating better chronic disease management and wellness tracking. Solutions like Apple Health Records and Human API allow patients and providers to access medical history and vital signs from multiple platforms, empowering patients to take control of their health data.

Challenges and the future outlook

Despite their transformative potential, healthcare APIs face challenges such as incomplete data exchange, security concerns, and cost barriers. However, continued API adoption promises a future where healthcare becomes more connected, personalized, and patient-centered.

 

Paubox’s solution

Paubox offers a HIPAA compliant Email API designed to securely automate the sending of transactional emails while maintaining the highest standards of data protection. It allows healthcare providers to send emails that contain protected health information (PHI) with ease, ensuring compliance with HIPAA without adding extra complexity to the process. The API uses TLS encryption to safeguard emails in transit, and all communications are secured from the moment they leave your system until they arrive in the patient’s inbox.

The main features of Paubox’s Email API include customizable dynamic templates, which enable personalized email content, and webhooks that provide real-time data on email delivery status. Additionally, the API allows seamless integration into existing applications, making it easier for healthcare providers to automate communications such as appointment reminders, lab results, and patient onboarding notifications. The API is also equipped with audit logging and reporting tools, which allow providers to track email interactions for compliance and security audits​.

Paubox’s solution is ideal for healthcare organizations looking to improve operational efficiency by automating patient communications while ensuring compliance with strict data protection regulations like HIPAA.

FAQs

How do healthcare APIs improve data exchange between systems?

Healthcare APIs enable seamless communication and data exchange between different systems, such as electronic health records (EHRs), insurance platforms, and laboratory information systems. APIs allow healthcare providers to access and share patient information more efficiently, improving coordination of care and reducing administrative burdens.

 

Are APIs in healthcare HIPAA compliant?

Yes, APIs in healthcare can be designed to be HIPAA compliant. To meet HIPAA regulations, healthcare APIs must ensure that data is encrypted, access is controlled through strong authentication methods, and audit trails are maintained to track who accesses sensitive patient information. These features ensure that APIs protect patient data while allowing secure and efficient data transfers​.

 

What challenges do healthcare providers face when implementing APIs?

One of the primary challenges healthcare providers face when implementing APIs is ensuring interoperability across different systems and platforms. Many healthcare organizations use a wide range of software applications, such as EHRs, patient portals, and billing systems, which may not be designed to work together seamlessly. Additionally, maintaining compliance with privacy regulations like HIPAA and ensuring that APIs are secure from cyber threats can also present challenges. Proper integration, staff training, and continuous monitoring are necessary to address these hurdles and ensure the smooth operation of API systems.
