The High Risk Care Managers work in concert with the patient's primary care team and CIN experts to provide direct telephone and/or visit based care management services addressing comprehensive challenges that impact the health of the patient, while reducing unnecessary healthcare utilization. Working with the most vulnerable patients, these nurses collaborate with the health care team to establish a comprehensive goal-driven care plan, that addresses the patient's chronic disease, psychosocial, behavioral health, hospital utilization, pharmaceutical, and social determinants of health barriers.
