Device Interface - NDD EasyOne Connect vbase

The following is referring to the NDD EasyOne Connect spirometry system (also referred to as Easy-On or EasyWare). Contact your MIE Implementer to see if your spirometer system model can be interfaced or quoted.

Introduction

NDD’s EasyOne Connect software employs a plugin system that EMR vendors can use to provide bi-directional connectivity.  Based on the Due List,  SYSTEM  can provide the NDD software with a list of people due for testing, along with key demographic information, avoiding dual-entry of this data.  Test results can be uploaded to  SYSTEM  to create PFT documents, including graphed curve data.

Plugin Download and Installation

  • From Control Panel > Plugins, use the “Download NDD Easy-On Plugin” link to download the EHR plugin to a PC that has the NDD software already installed.
  • If Internet Explorer was used to download the file, rename the file from “nddplugin_mie.zip” to “nddplugin_mie.zemr”
  • Run the EasyOne Connect software as an administrator.
  • Click Utilities > Configuration.
  • Click the EMR tab.
  • Install new.
    • Find the plugin file you downloaded, called nddplugin_mie.zemr .
  • From Selected EMR System, choose MIE EMR Plugin.
  • For EHR URL, enter the  SYSTEM  URL as seen in a web browser, starting with https:// and ending with .cgi .  Omit any page-specific parts of the URL that start with a question mark “?”.
  • Check “Include Curve Data” and “Include Trial values” to get discrete data included in PFT documents.
  • Close the NDD software.  The next steps require the software to reload to work.

Establishing Login Credentials

The plugin will get and send data under the authority of a  SYSTEM  user.  Each user on each PC that runs the NDD software will need to provide credentials to allow this to happen.  There should be a 1-to-1 relationship between client PC users and  SYSTEM  users.

  • In  SYSTEM , the user should go to Quick View > Select Portlets.
  • Make sure the Devices portlet is selected.
  • Once per user (not on every workstation), click the One-Time setup link.  This creates a public/private key pair and a login trust record.
  • On each workstation, the user should click the Get client credentials link then click in the box to copy their credentials to the clipboard.
    • Be sure all of the text is copied.  It should should:
      • Start with “—-BEGIN RSA PRIVATE KEY—-”
      • End with “—-END RSA PRIVATE KEY—-”.
  • Open the NDD software, then go to Patients.
  • Click “Search EMR”.  A warning that the software could not make connection to EHR system should display.
  • Click “Search EMR” again.  This time you will be prompted to enter your  SYSTEM  username.
  • Click in the “Credential Data” text box and Ctrl+V or Right mouse click and Paste.
  • If successful, this setup should only need to be done once per user per PC.

Finding People Due for Testing

The “Search EMR” function under Patients should show all people with a pending PFT order on the due list that the user has access to view.  If you double-click the name of a patient found this way, an “EMR Session” has begun.  This is a streamlined workflow that will start a test and automatically upload the results to  SYSTEM  once complete. 

Uploading Data to  SYSTEM

If a test was performed “offline”, perhaps with a laptop that did not have network connectivity, even for a patient whose information had to be manually entered in the NDD software, it is still possible to upload the data once connectivity can be established.

  • In the NDD software, be sure to set the “Patient ID” to match the partition-number of the record in  SYSTEM , eg “MR-12345”.
  • Go to the list of tests for that patient in the NDD software and single click to select the test you want to upload.
  • Click the double-right arrow in the middle of the row of icons to expand options.
  • Click the EMR button.
  • If there were no problems uploading the data, you should see “Successfully uploaded data to EMR system.  Doc ID: ###”.
  • To view the document in  SYSTEM :
    • From the side menu click E-Chart.
    • Select “Doc ID” from the search options.
    • Type the number shown in the popup after “Doc ID:”.

Calibration

NDD states that their system “… delivers unprecedented accuracy and reliable results without needing calibration.”  If regulatory, legal, or other professional organization (ATS/ERS) requirements necessitate record keeping of calibration despite this, the device can be calibrated and the results can be stored in  SYSTEM .

  • To perform calibration of a spirometer, you will need a 3-Liter calibration syringe which can be purchased from NDD.
  • Each spirometer has a unique serial number.  This can be found on a sticker on the base of the grip of the handheld spirometer.
  • The suggested workflow is to use the Asset management feature of  SYSTEM  to create a chart for each spirometer.
    • This can be enabled by showing the “Assets” sidemenu tab
    • Click “Add New Asset”
    • The name field is how we uniquely identify devices, so this must be entered exactly.
      • This name can be found in a PFT document that was created using the device.
      • If you use all the same kind of device, then you can assume they will follow the same pattern, with just the serial number being different.
  • To perform calibration in the NDD software, go to Utilities > Check Calibration
  • After calibration, there will be a special patient created in the NDD patient list, named “Calibration Check” with an ID that is the serial number of the device.
  • Double click on the Calibration Check row to see a history of calibrations
  • Click to select the Calibration Check test that you want to upload
  • Click the double-right arrow in the middle of the row of icons to expand options.
  • Click the EMR button.
    • The Doc ID is the unique ID of the calibration document and you can find it in the device’s asset chart, or by searching for it by ID.
    • The calibration document will be a PFT document, and the result of calibration will be shown as the Interpretation.
  • If you try to upload calibration for a device that hasn’t yet been entered as an asset, you will see an error like this displayed:
    • After registering a chart with that name, you should be able to upload the calibration.
