1. "Known Issues" are issues with the indicators or resources that have been raised by or brought forward to the Core Indicators Work Group but have not yet been addressed by the group. They are documented in more detail on the Identified Indicator/Resource Issues page. There is a link to this page included under this column for every indicator with an identified issue.
2. "Last Date Revised" refers to the last date that the resource underwent a complete review. Minor changes may have occurred since this date and will be captured in the "Changes Made" section of each indicator along with a description of the changes made during any complete review.
3. "Under Revision" refers to any resource which is currently undergoing a complete review either by the Core Indicators Work Group or by one of the current subgroups. Go to the Our Volunteer Workforce page for more information on these groups. "Under Development" refers to a new resource that is being developed and has not yet been finalized. "Needs Update" refers to resources which at minimum require updating to reflect the Ontario Public Health Standards (OPHS) and Protocols rather than the Mandatory Health Programs and Services Guidelines (MHPSG) and/or change of source, for example to reflect the switch from the Provincial Health Planning Database (PHPDB) to IntelliHEALTH. Resources with other know issues are also marked as "Needs Update".
