REST API - FHIR, GraphQL, Reactive API &
Subscriptions
We provide FHIR API, Subscriptions, GraphQL,
and SQL API. It can be extended with Custom Operations.
Service supports all major versions of FHIR: DSTU2, STU3, and R4. Strict validation ensures data consistency and integrity for all FHIR resources. With ”Subscriptions”, users can execute custom logic in their applications when specific data is changing.
GraphQL API
System supports default GraphQL implementation without any extensions. It generates different GraphQL scalars, objects, queries with args and unions from FHIR metadata.

Auth Server
An authentication server is used to verify credentials when a person or another server needs to prove who they are to an application. The Auth0 Identity Platform takes a modern approach to identity and enables organizations to provide secure access to any application, for any user. Auth0 is a highly customizable platform that is as simple as development teams want, and as flexible as they need.
OpenID is an open standard and decentralized authentication protocol promoted by the non-profit OpenID Foundation. It allows users to be authenticated by co-operating sites (known as relying parties, or RP) using a third-party identity provider (IDP) service, eliminating the need for webmasters to provide their own ad hoc login systems, and allowing users to log in to multiple unrelated websites without having to have a separate identity and password for each. System has built-in OAuth 2.0 OpenID Connect server and can work as Resource Server.

Access Control
Provides a flexible model to customize request authorization rules. User is allowed to declare a set of checks for all incoming requests. If the incoming request satisfies those checks, it's considered authorised and being processed further. Otherwise the request is denied and the client gets 403 Unauthorized. Such checks are declared with AccessPolicy resource.
Module HL7v2 / X12
Integration adapters comes with HL7 v.2 and X12 integration modules. Not all the systems that interact with modern healthcare application speak FHIR yet. Support of other interoperability standards takes a lot of burden from developers.
FHIR/Bulk API
Providing exchange data with external FHIR systems.

Custom Resources
Resource has a type. All resource types are described with "meta-resources" - Entity and Attribute. Entity defines the resource or complex type and set of Attributes describe its structure. Not all healthcare data fits the FHIR data models. System allows adding custom resources and attributes with an easy update of metadata over RESTful API.

FHIR Resources
System stores FHIR resources almost as is with 3 types of isomorphic transformations:
Union (Choice) Types: some elements can have multiple types.
First-Class Extensions - while FHIR uses two different ways to define core elements and extensions, System provides unified framework to describe both. It supports user-defined attributes or "first-class extensions". So, can define new attributes (elements) for existing (FHIR) resources.

Audit
System automatically logs all auth, API, database and network events, so in most cases basic audit log may be derived from System logs. FHIR Standard introduced AuditEvent resource which into FHIR ecosystem. System provides comprehensive FHIR API for AuditEvent resource.
Terminology
System terminology comes with FHIR, ICD-10, SNOMED, RxNorm, LOINC, and US NPI. Users can extend it with other terminologies and custom value sets.

Database
FHIR-aware PostgreSQL with SQL on FHIR
support System uses PostgreSQL exclusively but squeezes everything out of this database
technology. Most of System flexibility and performance is coming from advanced PostgreSQL
features like binary JSON, rich indexing system, etc. SQL is the second System API, which
gives you extra power on structured data.

Real-time integration pipeline
Export while importing data from CCDA
documents, there are many nuances on every step. How does your system receive CCDA
documents? What data elements do you want to persist? How would your system deduplicate
patient records?
Because answers to those questions are strictly system-specific, System does not provide a ready-to-use solution here. But we can implement new pipeline, using any favourite technology stack.

Receiving CCDA files
The first step is to understand how System
would receive CCDA files. In case when we have an user-facing application like Patient
Portal or EHR user will upload his CCDA file manually. The other common case is bulk import
from remote storage like SFTP server or S3 bucket.
Processing received files is usually a resource consuming task, so it’s better to make it asynchronous. This way our system would be responsive while the file is being converted, and the entire conversion process would be much more manageable. For example, we may notice a bug in the CCDA converting logic, our engineers will fix it and we would like to process all recently received files. Holding all received files in a queue will give you this ability.
There are dozens of ways to set up such a queue, probably the most simple one is to use the DocumentReference resource (if we know a patient to whom this document belongs). Alternatively we can use a dedicated queue service like Apache Kafka or just a custom table in our RDBMS. However, despite the storage we would use, we would store the original CCDA file to be able to access it at any time.
On the next step some kind of background job or a worker will pick received files from a queue and process them one after another.

Timely and efficient diagnostic became one of
the ways to prevent the COVID-19 infection spread.PCR tests show whether the carrier is
infected and proved to be inefficient in 30-40% in field testing and even in lab testing. It
is also non-instant, uncomfortable and costly. Temperature screening with handheld devices
is easy but inaccurate and detects only a fever, not the infection and useless in
asymptomatic cases. The user just coughs in the microphone of any smartphone a few times for
instant result provided by neural network. We use ML (machine learning) algorithms to detect
the COVID19 specific resonance in vocal sounds (coughing, speaking, etc.). This make field
screening instant, non-invasive, supplies free.
