WI OASIS Educational Forum

DQA is sponsoring a new educational venue for Wisconsin HHAs to help keep current with evolving OASIS information.

Each OASIS Educational Forum will be conducted over the internet utilizing the Adobe Connect Meeting software. Adobe Connect Meeting is web-conferencing software that allows users to connect to live meetings/presentations over the internet.

The next forum will be on Thursday, August 14, 2014, starting at 1:00 pm.

Use this website to join the meeting:
Select "Enter as a Guest" and enter your agency name and number of attendees participating.

It is highly recommended that you test your computer for ‘connection compatibility’ prior to the day of the Forum. For more detailed information, please see the complete article published in the DQA Quarterly Information Update - January 2013.

Listed below are the recordings of previous OASIS Educational Forums:

CMS OASIS-C Training Modules 

CMS has developed 16 online modules to assist HHA staff to accurately complete OASIS-C assessment questions. These modules include conventions for accuracy, and cover each of the OASIS-C domains. Guidance includes item intent, time points for completion, response-specific instructions, data sources, and resources.

Each module has an accompanying set of PowerPoint slides that should be printed and available to the user prior to beginning each module. The modules are available on the CMS SurveyorTraining OASIS website.(exit DHS)

CMS YouTube Training Videos

These training videos were developed prior to the OASIS-C Training Modules noted above.

Other Educational Resources

OASIS Submission User's Guide Effective 01/01/2015 for ASAP is now available under the QTSO OASIS User Guides & Training website. Refer to Appendix A Quick Reference to OASIS Submission, Submission Status, and Final Validation Reports.  The access to the CMS OASIS System will not change.  The same CMSNet User IDs and OASIS Individual User IDs will be used to submit OASIS records to ASAP.  The OASIS Submissions link on the CMS Welcome page will be changed to access ASAP instead of the current submission web page.

Windows XP

  • Effective October 1, 2014, the QIES systems will no longer support Windows XP operating system and Internet Explorer 8 or below.

IE 8 (Internet Explorer)

  • For security purposes, the QIES systems will be programmed to block the browser’s access if IE 8 or below is used to access the QIES systems.

  • In such situations, users will receive a message to upgrade to a supported version of the browser. Windows XP does not support any higher versions of IE than IE 8.

  • Refer the the CMS System Requirements available on the QTSO website.

OASIS Assessment Deletion Request

Refer to the OASIS Correction Policy for HHAs (above) for information on when to submit an OASIS Deletion Request.  Email Chris Benesh to obtain the required CMS form that must be completed to request a removal of a previously submitted and accepted OASIS record.

OASIS Data Specifications

Effective January 1, 2015, OASIS assessments will be submitted to CMS via the CMS OASIS Assessment Submission and Processing (ASAP) system. The submission format for both OASIS-C and OASIS-C1 assessment data will change from the current fixed-format record layout to Extensible Markup Language (XML).  The CMS OASIS Data Specifications web page includes information for both OASIS-C and OASIS C1. (exit DHS)

User IDs/Passwords Required

In order to submit OASIS records and/or access CASPER reports, users must have both a CMSNet (Verizon) User ID and a OASIS Individual Login ID to submit OASIS records/and or to access CASPER reports.  Both of these IDs and passwords are assigned to an individual and should not be shared. 

CMSNet User ID

New users need to complete the CMSNet Access Request Form that is available QIES Technical Support Office (QTSO) website located at: (exit DHS)

OASIS Individual User Login ID Requirement

Each HHA and each of their respective branch locations are allowed two individuals with OASIS Individual User IDs to submit OASIS assessment information and view CASPER reports.  It is the agency’s responsibility to revoke access for any users who no longer require access to this data.  Revoking the account of a user who no longer requires access permits the agency to request a personal login ID for an additional user.

To obtain an OASIS Individual User Login ID, a request must be submitted to the QIES Technical Support Office (QTSO) using the OASIS Individual User Account Request form available on the QTSO website located at: (exit DHS)  This same form is used to revoke access for a user.

OASIS Individual Login Passwords

A user selects their own personal login password when they register for an OASIS Individual User ID.  The password must meet stringent password rules that are available to view on the password web page.  Passwords are set to expire in 60 days.  Users must enter a new password when they are prompted to change their password or they may use the QIES User Maintenance application that is available on the OASIS Welcome Page to change their password at any time prior to the 60 day expiration date.  

Forgot OASIS Individual Login Password and Inactivated Accounts

If an incorrect OASIS Individual Login password is entered too many times the account will be made inactive.  If the user does not log into CASPER reports within 60 days, their account will also be made inactive.  Inactive accounts will not be able to submit OASIS assessments.

One indication of an inactive account or an expired password: after attempting to login the following message appears, "Authorization Required", indicating the server can't verify the appropriate access credentials.  

To reactivate an OASIS personal account, follow these steps:

  1. On the State OASIS Welcome page select the QIES User Maintenance link.
  2. Select  "Forgot your password or Inactive Account?".
  3. Enter your Personal Login ID and answer the three security questions and follow the directions provided.

Providing answers to the security questions were part of the process for registering for an individual OASIS account.  Users will have three attempts to correctly answer the security questions, after that, they are locked out and must contact the QIES Help Desk to reset their account, 800-339-9313.  

To avoid getting locked out be sure to log into CASPER or the QIES User Maintenance application at least once every 60 days.
