What Physicians Need to Know

Healthcare API Support (FHIR/HL7)
Particle Health's API supports HL7u00ae FHIRu00ae R4 and C-CDA formats, aligning with the USCDI v2 standard and emphasizing 24 clinically significant FHIRu00ae resources. It also offers customer EHR integrations via HL7u00ae for specific requests.
HIPAA-Compliant Infrastructure
The platform is 100% committed to data privacy and security, exceeding legislative requirements for PHI. It is HIPAA compliant, SOC 2 compliant, and HITRUST certified. Data at rest is encrypted using AES, and it includes OAuth 2.0 compliance and Multi-factor Authentication (MFA).
Clinical NLP Capabilities
Particle Health offers 'Snapshot' for AI-generated summaries of clinical records to reduce information overload, and 'Signal' for real-time, pertinent alerts on high-risk patients to optimize care. These features imply underlying NLP-like processing for insights and summarization.
De-Identification Tools
Protected Health Information (PHI) is de-identified for Particle Health's internal analytics. The sandbox environment is provided as a PII- and PHI-free space for development and testing.
Medical Terminology Support
Particle's data normalization capability standardizes structured clinical codes and descriptions into easily understood clinical concepts. Its imputation engine enriches clinical data across records, reducing gaps and handling varied coding systems. The API supports refining queries using FHIRu00ae-supported medical coding terms.
Sandbox/Testing Environment
A fully-featured Sandbox environment is available for API development, populated with synthetic patient demographics and mock medical records for secure, PII- and PHI-free testing. It supports all production APIs and workflows, with a query limit of 500 per organization per day.
SDK Languages
As a REST API, Particle Health's API is accessible from most programming languages. Specific SDKs for the Particle Health API are not explicitly mentioned in the provided information.
Rate Limits & Pricing
Rate limits and quotas are implemented to manage traffic, returning a '429 Too Many Requests' HTTP status code if exceeded. Limits are typically tracked per minute and configured per project. Pricing is noted as approximately $1 per query, with enterprising options for higher volumes.
Certification Program
Particle Health has achieved HITRUST Implemented i1 Validated Assessment, SOC 2 compliance, and completed certification for Surescripts Medication History for Populations. There is no explicit mention of a developer certification program for using the Particle Health API.
Physician Tip

Leverage Particle Health's API to gain rapid access to comprehensive patient health histories, including medication, clinical, and ADT data, directly within your EHR. Utilize the AI-powered 'Snapshot' for summarized patient clinical history, reducing information overload and enabling a focus on patient care. Employ 'Signal' for real-time alerts on high-risk patients to optimize care, reduce intervention delays, and improve outcomes. The platform can assist in identifying gaps in preventative care and provides insights to enhance quality measures and reimbursements. For treatment purposes, data can be queried efficiently under HIPAA guidelines, streamlining patient onboarding and care management.

Particle Health offers extensive interoperability by connecting to all three nationwide health information networks (Carequality, CommonWell, eHealth Exchange), providing access to approximately 90% of EHRs through a single API. It also integrates with state HIEs (e.g., Healthix, Manifest MedEx) and the Surescripts network for medication data. The 'Particle for EHRs' solution enables EHR vendors to integrate the API for bi-directional record sharing. The API is designed for seamless integration into existing systems and workflows, aggregating and normalizing clinical records from diverse sources into standard formats.

Frequently Asked Questions

Particle Health API aggregates patient records from over 160,000 health systems and 320 million FHIR-enabled records, providing a comprehensive view of a patient's history through a single integration. It can streamline patient onboarding, medication reconciliation, and care coordination, and its AI-powered summarization feature can quickly distill complex clinical histories into actionable insights for your team.
Particle Health is HITRUST certified, SOC 2 compliant, and HIPAA compliant, ensuring robust security and privacy for Protected Health Information (PHI). They employ data encryption at rest, OAuth 2.0, and multi-factor authentication, exceeding legislative requirements to safeguard sensitive patient data used in any integrated AI applications.
While Particle Health boasts a high success rate in finding patient records, it's not 100%, and its effectiveness can depend on the inherent limitations of FHIR standards and access to various data sources. Additionally, the API has rate limits and quotas to manage traffic, which could impact very high-volume, real-time AI processing if not properly managed.
Particle Health differentiates itself by acting as a 'network of networks,' aggregating data from numerous EMRs and HIEs into a standardized FHIR, Flat, or CCDA format through a single API. Alternatives like Redox, 1upHealth, or Google HealthAPIx also offer interoperability, but Particle focuses on simplifying the complex integration landscape to provide comprehensive patient data quickly.
Specific pricing details for physicians are not publicly disclosed, but API services typically involve costs based on factors like data storage, request volume, and potentially advanced operations like de-identification. Healthcare organizations are generally encouraged to contact Particle Health directly for a customized quote, often implying a subscription or usage-based model.
Particle Health adheres to HIPAA's 'Purposes of Use' framework, allowing data disclosure for Treatment, Payment, and Operations (TPO) without explicit patient authorization. However, for 'Individual Access' or other purposes outside TPO, explicit patient consent is required to ensure compliance and protect patient privacy.
Yes, Particle Health supports near-real-time data access for various clinical workflows and offers data in FHIR, Flat, and CCDA formats for integration. While the FHIR R4 endpoint for v2 APIs was noted as temporarily disabled for certain implementation requirements, the platform generally aims to provide timely and structured data for seamless integration.
