PURPOSE: To determine the changes in attitudes toward the inclusion of acardiometabolic health nurse for the physical healthcare management of peoplewith serious mental illness following a 6-month trial. DESIGN AND METHODS: Repeated survey of nurses working in a regional menta lhealth facility. FINDINGS: Nurses working in mental health were initially supportive of the role. A6-month trial of a cardiometabolic health nurse in the workplace reduced ambivalence and increased positivity toward the role. PRACTICE IMPLICATIONS: Reduced ambivalence and improved positivity toward the role may facilitate less organization resistance to the implementation of acardiometabolic health nurse in the mental healthcare setting. Specialized training and role recognition may be needed to further support this role.
