HealthShare

Syndicate content 59 

++Update: August 2, 2018

This article provides a reference architecture as a sample for providing robust performing and highly available applications based on InterSystems Technologies that are applicable to Caché, Ensemble, HealthShare, TrakCare, and associated embedded technologies such as DeepSee, iKnow, Zen and Zen Mojo.

Azure has two different deployment models for creating and working with resources: Azure Classic and Azure Resource Manager. The information detailed in this article is based on the Azure Resource Manager model (ARM).

Hello!

This article is a small overview of a tool that helps to understand classes and their structure inside the InterSystems products: from IRIS to Caché, Ensemble, HealthShare.

In short, it visualizes a class or an entire package, shows the relations between classes and provides all the possible information to developers and team leads without making them go to Studio and examine the code there.

If you are learning InterSystems products, reviewing projects a lot or just interested in something new in InterSystems Technology solutions — you are more than welcome to read the overview of ObjectScript Class Explorer!

Hello guys,

I've got this piece of code which runs the method "WebMethod", that belongs to %SOAP.WebBase.cls.

It grabs the outcome from an internal webservice we have and after that, it writes into a file.

The thing is, when I browse the file contents, I realize that in the place where a special character should be, I see a question mark.

By querying the same webservice from a special soap tool called "SoapSonar" (I've been using this for years), the outcome shows up this special character (shows it properly).

There are often questions surrounding the ideal Apache HTTPD Web Server configuration for HealthShare.  The contents of this article will outline the initial recommended web server configuration for any HealthShare product. 

As a starting point, Apache HTTPD version 2.4.x (64-bit) is recommended.  Earlier versions such as 2.2.x are available, however version 2.2 is not recommended for performance and scalability of HealthShare.

Hi All -

I was wondering if the below query could be enhanced to automatically look back 24 hours from the current datetime the query is run. As is now I, of course, have to update the date range in the WHERE clause manually.

The query is just getting all MessageBodyClassNames, counting them and then doing an AVG on TimeCreated and TimeProcessed. Nothing too complex.

 

SELECT MessageBodyClassName, count(ID) as Count_Of_Messages, avg(datediff(ss, TimeCreated, TimeProcessed)) as avg_processing_time_in_seconds

FROM %PARALLEL Ens.MessageHeader

HealthShare's new SDA extensions

Creating and working with the new SDA extensions for storage of custom data elements

 

In HSCore 15.01, there is a new way to store custom data elements.  HealthShare now had the ability to use custom extensions on many SDA elements.

This article will:

  1. Show how to set up your system to use SDA extensions
  2. Create a new SDA extension property
  3. Use the new SDA extension property in HL7 transactions
  4. Interact with the new data
  5. Show new SDA extension used in a customization of Patient Summary Report

Hi,

Can anyone  point me to an example of a DTL & Class method that can pull a base64 encoded PDF out of a MDMT02 message?

This is really asking for two things;

- how to make a DTL that extracts a specific subfield of an HL7 2.3 message into a message of its own,

and

- how to transform an base64 encoded document into its original binary form for writing to a file.

I'd also love to see an example of an HL7 2.n MDM^T02 ==> HL73.ITK2 non-coded CDA

XML to Json conversion

Hello,

Are there any utilities/api in HealthConnect 2016.2.1 that will allow conversion of XML virtual document to Json format? We were thinking to convert HL7 ADT message to XML via Ensemble DTL and then send it to another BP to convert to Json format for transmission via Web Services. To my understanding there isn't anyway to represent Json as a virtual object so it can be use for direct mapping of HL7 2.x message to Json via Ensemble DTL.

Thanks

Yuriy

GraphQL is a standard for declaring data structures and methods of data access that serves as a middleware layer between the client and the server. If you’ve never heard about GraphQL, here is a couple of useful online resources: here, here and here.

In this article, I will tell you how you can use GraphQL in your projects based on InterSystems technologies.

Create Patient via FHIR?

Hi,

I've been trying to create a patient using FHIR, but all I seem to get back is:

{"resourceType":"OperationOutcome","issue":[{"severity":"error","code":"invalid","details":{"text":"FHIR create interaction invalid for this end point"},"diagnostics":"FHIR create interaction invalid for this end point"}]}

I've tried a variety of requests and read operations work, but create doesn't seem to. Has anyone run into this? Any ideas? Thanks.

For testing purposes, I would like to create an EnsLib.HL7.Message from either a %String or a file on disk and pass it into a function in a unit test (outside of an Ensemble context). EnsLib.HL7.Parser appears to do the necessary parsing, but it also sends the message via Ensemble service rather than returning it as a value. Is there a way to leverage the parsing outside of a Ensemble service? Alternatively, is there another way to create an EnsLib.HL7.Message?

Hello,

I am working on a Rest Service that should accept a particular content type. How and where can I set the value?

I have tried setting the value %response.ContentType by overriding Page method OnPreHttp()  but from what I see this method never got executed. 

 

Thanks

Convert HL7 to FHIR

Hello Greetings-

I am exploring on converting HL7 to FHIR.

1. I saw there are built in DTLs “FHIR.FromSDA” and “FHIR.ToSDA” to convert SDA -> FHIR and FHIR -> SDA. Similarly Do Intersystems have DTLs for HL7 -> FHIR and FHIR -> HL7?

2. The reason why I am asking is, I see in HSLIB namespace HS->GateWay->HL7->HL7toSDA3 and HS->GateWay->SDA3->SDA3toHL7 DTLs. Like-wise I am trying to locate HL7 -> FHIR and FHIR -> HL7. Please help me to locate them

Hello everyone,

I'm trying to authenticate a user(Health Share clinician) from a Java Application. 

I 'm already connected to Caché and able to run SQL commands.

My question is: How can I authenticate a user using only SQL? In fact, what I want is verify if the users exists in the base and if the given password is the same used in Health Share.

There is a column 'password' in Security.users table but I'm not able to see its content, even so, I don't know which hash function to use to compare with.

For Global Summit 2016, I set out to showcase a Reference Architecture I had been working on for a National Provider Directory solution with State Level Instances and a National Instance all running HealthShare Provider Directory and all running on AWS Infrastructure.

In short, I wanted to highlight:

  • The implementation of Amazon Web Services to provision the infrastructure, including the auto-creation of the state level instances through Cloud Formation.
  • The use of the HSPD Broadcast functionality to Notify Upstream Systems Changes in Master Provider Data.
  • The implementation of a transformation of the standard Broadcast Object to HL7 MFN for interoperability.
  • The principals of Master Data Management applied to the Provider Directory.

Diagnosing the cause of <PROTECT> errors

If your application is raising <PROTECT> errors and you're finding it hard to work out why, here's a way to get additional information.

First, if auditing is not already enabled, turn it on:

Then use "Configure System Events" (highlighted above) and locate the event named %System/%Security/Protect. In the screenshot below I used the Filter field to do this (type "protect" - highlighted below - and press TAB):

Hi, 

I can't work out how to use the Cache CA Server to process certificate request from external clients!

We are setting up an interface where we use SSL/TLS 'Mutual Authentication' to allow a client system to securely transmit document to  our server. (they are off-site and hosting a service for us)

I am not a security expert, but my understanding of setting up mutual authentication where my instance of ensemble is the server, and it is receiving messages from a client is as follows

Is this available anywhere (for Health Connect)? I've found a few presentations but they are aimed at entry level.

We're looking at supporting more and more FHIR, REST plus OAuth interfaces in future. I've built some of this into older versions of HealthShare and Ensemble but it's desirable to move to supported versions. 

We would be using Healthshare as a facade to other systems.

On one HealthShare servers (RH Linux, 2017.1.1), I am not able to login to Studio for this server. When I select the server connection from the notification tray icon, choosing Remote System Access, Studio, then the server, the error I getting is:

Unable to log on to server {Server Name}

Communication link failure

I've tried using both DNS name and IP address, same result. Using Atelier, I am able to connect to the server using the same DNS name and Web Server Port that I'm trying in Studio.

In this posting I want to raise the profile of a feature that arrived in 2009.1 but is perhaps not very well known.

It is sometimes useful to make certain packages, globals or routines available to all of your namespaces. Of course you can add the necessary mappings whenever you create a new namespace, but here's a simpler way.

Tools for CDA/CCD?

I have a tool I absolutely love for HL7 v2 analysis and manipulation. It's called 7edit.  I'm wondering if there is anything similar for HL7v3/CDA/CCD.  I know it is considerably more complex, but I still have hope.

So far the best resource I've found is http://www.cdapro.com/.  I'd love to hear anyone else's tips for tools or resources.

Enterprise Monitor and HealthShare

Enterprise Monitor is a component of Ensemble and can help organizations monitor multiple productions running on different namespaces within the same instance or namespaces running on multiple instances.

Documentation can be found at:

http://docs.intersystems.com/ens20161/csp/docbook/DocBook.UI.Page.cls?KEY=EMONITOR_all#EMONITOR_enterprise

In Ensemble 2016.1 there were changes made to make this utility work with HealthShare environments.

This article will:

  • Show how to set up Enterprise Monitor for HealthShare sites
  • Show some features of Enterprise Monitor
  • Show some features of Enterprise Message Viewer

For this article, I used the following version of HealthShare:

Cache for Windows (x86-64) 2016.1 (Build 656U) Fri Mar 11 2016 17:42:42 EST [HealthShare Modules:Core:14.02.2415 + Linkage Engine:14.02.2415 + Patient Index:14.02.2415 + Clinical Viewer:14.02.2415 + Active Analytics:14.02.2415]
