Care Companion is a mobile phone application for patients which supports the engagement of patients with the Care Management team of nurses, pharmacists, social workers, and others in the process of improving individual patient outcomes. Most patients have experienced the frustration of not knowing their care plan nor how to become engaged to ensure the plan’s success. Health Catalyst’s patient engagement tools solve this problem by leveraging smart phones and mobile connectivity. The tools enable secure messaging, assessments, care planning, and the associated activities and education that engage patients in collaboration with their care team. Family, friends, or caregivers can be invited to share in these plans and communications to ensure patients receive the best care.
