Primary care providers are often first-line responders for complex patients. In rural and underserved areas, where access to specialists is limited, complex medical and psychiatric concerns are managed by providers who often feel under-resourced and isolated. Tele-mentoring interventions like Project ECHO can address this challenge. This poster presentation will provide an overview of ECHO Ontario Complex Patient Management, a tele-mentoring program that virtually connects a specialist team with inter-professional providers working in rural and remote areas to build provider capacity in the assessment and management of complex medical and psychiatric patient health concerns. Through the sharing of knowledge and best practices, and anonymized real time case-based learning, providers are able to apply what they have learned to support their own patients with complex health needs within their local communities. We will also describe the evaluation findings from this 12-week virtual intervention, which demonstrates participants are highly satisfied and engaged with the program, and feel more confident after their participation.
