About Message Failure Management (MFM)

MFM involves knowing about the:

Path of all inbound and outbound WTIS interface messages
Tasks involved in the MFM process
Accountabilities of the MFM Specialist and Ontario Health in the MFM process
MFM guiding principles

Note: It is important that you are familiar with the business rules related to dates and waitlist entries. The following specification documents are available on the ATC Information SiteATC Information Site:

WTIS Interface Message Path

The facility source system sends an interface message to the WTIS interface engine:

Facilities with a Standard level of integration send messages to close a waitlist entry
Facilities with a Complex level of integration send messages to add or edit a patient or to open, edit or close a waitlist entry

Two types of validation are performed on received messages:

HL7 – validates message structure and syntax to ensure compliance with WTIS HL7 specifications
Business Rules – validates message content to ensure data quality is maintained

The WTIS interface engine returns an acknowledgement message to the facility source system after HL7 validation. This can be either positive, or negative, in which case it will outline the specifics of the HL7 message received.

If	Then
The message passes HL7 validation	The WTIS then validates the message against business rules.
The message passes business validation	It will likely be deemed a success. If it does not, it will be deemed an error. In rare circumstances, a message can result in an error that is not related to HL7 and business rule validations.

Both successful and unsuccessful message types are stored in the WTIS database. Message details can be accessed through the MFM functionality within the WTIS.

Note: The WTIS will not partially process a message. Any message that results in an error is not processed. If one part of a message is wrong the whole message is deemed wrong.
