Hospital Integration Environment

Ancillary systems do not communicate directly with SXA.SXA interfaces with other applications and HL7 messaging is mediated and

routed via an Interface Engine.Interface Engines also provide some services for minor

routing/remapping/reformatting of messages to support differences between systems.

Interface Engines provide a reliable store-and-forward mechanism for message flow management.

Understanding the Interfaces Sub Components

HL7 Connections- Provide TCP/IP Socket connection Controls the messaging flow with Interface Engine Allow SXA to communicate with various ancillary systems

HL7 Executive- Monitor and manage the work of all the other components in the HL7 Interfaces system One executive per enterprise

HL7 Manager- Not directly involved in the processing of messages Wakes up the workers and assigns the message to the worker HL7Manager & Worker's are on same server Pool of HL7 workers and manages the communication with HL7 executive

HL7Workers- Process HL7 messages Reports to the HL7 manager as they reach an "idle" state for the next patient record to be

processed HL7Manager & Workers are on same server

HL7 Executive Components cont..

HL7 Executive

The HL7 Executive is comprised of seven tasks:

Remote Client Task - any control or query application that connects to the HL7 Executive

Remote Manager Task - any operation initiated in the HL7 Executive by a HL7 Manager

Remote Connection Task - any operation initiated in the HL7 Executive by one of the connections in the HL7 Connection server



HL7 Executive Tasks Continued:

Outbound Event Task - updates and queries tables in the Primary Active database server

Configuration Task - retrieves configuration data from Enterprise Server

Environment Management Task - responsible for various management tasks

Monitoring Task - checks interface components and restarts failed components



HL7 Connection

The HL7Connection is comprised of three tasks:

Inbound connections have:

Received Message Task - receives messages from integration engine

Message Registration Task - implements flow control for messages inserted into the manager’s input queue

Outbound connections have:

Send Message Task - sends SXA Clinical Manager generated messages to the integration engine

HL7 Manager

The HL7 Manager is comprised of the following tasks:

Remote Executive Task - performs status queries, configuring, starting and stopping the manager

Remote Worker Task - acquires client IDs from the HL7 Manager

Manager Background Processing Task - requests new client IDs from the HL7Executive and notifying the HL7Executive of status changes

Worker Monitor Task - ensures the workers are still running


HL7 Manager/Worker Components cont..

HL7 Worker

The HL7 Worker is comprised of two tasks:

Remote Manager Task - HL7Manager initiates requests via this task

Message Processing Task - responsible for requesting a client ID from the HL7Manager and processing all the events associated with the returned client ID

Eclipsys standard Format- “eStd Message Format”

Eclipsys has defined a standard HL7 message format to support ADT, Orders, Results, and Medical Document Messaging.This standard format is called as eStd message type format.

The format is used to exchange information between Eclipsys Sunrise applications, and to send and receive order information , results information , ADT information etc to and from external third-party systems.

All messages received by the SIM must be in the eStd format prior to being routed by the SIM Router.

Note: AM-PFM outputs ADT messages already composed in the eStd ADT format.


Sunrise Integration Module (SIM Overview)

Provide packaged solutions used to integrate the Eclipsys products.The SIM is constructed and maintained using Sunrise eLink.Can be deployed at customer sites and it can interact with other 3rd

party integration engines. Allow more accurate implementation planning, estimates and

integration pricing models .Deliver a pre-configured solution, which accommodates unique,

configurable customer requirements.Reduce the number of interfaces, which reduces the costs to customersThis SIM software is free (customer pays for implementation hours).


Sunrise Integration Module Components…

Components include the Message Center, Message Configurator and eLink console

Message Center Standard Send/Receive TCP-IP connectivity components SIM Router – pre-configured message router delivered for each message type

(ADT, Order, Result and MDM), routes HL7 events and segments per event Application Adapter –Total Integration package for a specific application

including translators that convert messages from or into the Eclipsys standard format per supported message type SIM Configurator -Web-based application that provides a user interface to

allow site-specific customizations as needed eLink console- Used to provide monitoring, start/stop and status capabilities


Sunrise Integration Module - Message flow

The sending application creates a message and sends it via TCP-IP to SIM.An application adapter translates the message and outputs a message in the

Eclipsys standard message format according to the specifications.The SIM router determines which applications are to receive the message.

The same process is followed for sending messages to Eclipsys applications and SIS as for receiving them. An Application Translator is supplied if necessary, to convert messages from the eStd format into the format specified by the application, along with a Send translator.


eLink Overview (Eclipsys Interfaces Engine)

eLink is an enterprise application integration solution that provides application-to-application integration support in a unified design environment.

eLink is scalable; it can be deployed as an executable to support a single interface. eLink supports connections in different environments like NT, UNIX etc enabling

disparate systems, platforms and software applications to transparently share, pass and update multiple forms of data between systems in real-time.

eLink captures and sends data from systems using processes called host connections. Data is translated using processes called translators. While data is being captured,

translated, and sent, it can be stored in a queue.


Sunrise e-link Interface Components

Management Server- The Management Server controls the eLink environment Installation of New interface components Controls and monitors the data flow Maintains the logs and queues

Archive Server- Archives the records in the system Determine the moving and processing of the records through the system.

Service Manager- Service Manager normally runs as a service Responsible for directly communicating with and monitoring both Archive Server and Management Server. Start both Archive Server and Management Server processes when it is started and stop both processes when it is stopped .

Console- The Console is the graphical user interface (GUI) into the Management Server The Console is primarily used to start and stop translators Provide information on the current status of the logs and queues associated with each translator.

Designer- Allows the construction and compiling of translators without writing any code.


Sunrise e-link Interface Componentscont…

Translator: An executable program that manipulates and moves data between applications using host connections, databases, or web-browser applications.

Application Translator : Reads the message from a queue, reformats the message according to the requirements of a specific target application

Communication Translator : Receives data from or sends data to an application using a host connection

Application adapter: Translates the message and outputs a message in the Eclipsys standard format according to the specifications.

Router Translator : Translator that reads each message formatted to Eclipsys standard HL7 message specifications and routes the message to right target application

Queue-Reliable storage area for messages to be passed between router, application, or communication translators. Messages are processed in first-in first-out (FIFO) order.

Both Archive Server and Management Server are down.

Service Manager is down therefore no status is available for theprocesses.


Eclipsys Custom Interfaces

SCM and SIS Integration-Eclipsys Corporation (Eclipsys) and Surgical Information Systems (SIS) have

a number of mutual customers who are currently using or implementing Sunrise Clinical Manager (SCM) and Surgical Information System (SIS).

To enhance the workflow between these systems, SIS and Eclipsys have come together to offer a combined solution that brings integration, not only delivering greater data sharing, but more importantly driving improved workflows throughout the clinical and administrative processes associated with surgery.

On-line, real-time interface complying with Eclipsys eSTD specification
