Current evaluation and future needs of a mental health data linkage system in a remote region: a Canadian experience.

Linking client data across care sectors and agencies is becoming essential to ensure continuity of care, evaluation, and planning of mental health services delivery.

It is a voluntary system currently used by 30 of 40 mental health programs.
