The wide range of sectors included in the discussion is the ideal setting for making a decision as to whether acutely elevated risk factors across a range of professionals are indeed present. If the circumstances do not meet this threshold, no personal information may be disclosed and no further discussion of the situation should occur. However, if at this point the presenting agency/organization decides that, based on the input and consensus of the table, disclosing limited personal information (e.g., the individual's name and address) to the group is necessary to help eliminate or reduce an acutely elevated risk of harm to an individual(s), the parties may agree to limited disclosure of such information to those agencies/organizations at filter three.

Filter Three: Limited Identifiable Information Shared

If the group concludes that the threshold of acutely elevated risk is met, they should determine which agencies/organizations are reasonably necessary to plan and implement the intervention. Additionally, the presenting agency should inform the table of whether the individual has consented to the disclosure of his or her personal information to any specific agencies/organizations. All those agencies/organizations that have not been identified as reasonably necessary to planning and implementing the intervention must then leave the discussion until dialogue about the situation is complete. The only agencies/organizations that should remain are those to whom the individual has expressly consented to the disclosure of his or her personal information, as well as those that the presenting agency reasonably believes require the information in order to eliminate or reduce the acutely elevated risk(s) of harm at issue.

Identifying information may then be shared with the agencies/organizations that have been identified as reasonably necessary to plan and implement the intervention at filter four.

Any notes captured by any professionals that will not be involved in filter four must be deleted. Consistency with respect to this “need-to-know” approach should be supported in advance by way of an information sharing agreement that binds all the involved agencies/organizations.

*Note: It is important that the agencies/organizations involved in multi-sectoral risk intervention models be reviewed on a regular basis. Agencies/organizations that are rarely involved in interventions should be removed from the table and contacted only when it is determined that their services are required.

Filter Four: Full Discussion Among Intervening Agencies/Organizations Only

At this final filter, only agencies/organizations that have been identified as having a direct role to play in an intervention will meet separately to discuss limited personal information required in order to inform planning for the intervention. Disclosure of personal information in such discussions shall remain limited to the personal information that is deemed necessary to assess the situation and to determine appropriate actions. Sharing of information at this level should only happen to enhance care.

After that group is assembled, if it becomes clear that a further agency/organization should be involved, then professionals could involve that party bearing in mind the necessary authorities for the collection, use and disclosure of the relevant personal information.
