This document outlines the role of medical social workers in an outpatient setting. It begins by defining medical social work and outpatient care. Medical social workers in outpatient settings, known as ambulatory social workers, help connect patients to services, provide mental health treatment, and aid in care coordination, patient navigation, discharge planning, and legal/financial assistance. Their scope of practice includes assessment, counseling, crisis intervention, advocacy, case management, psychoeducation, research, and policy work. Key functions involve early prevention, recognition of burnout, referrals, communication, and collaboration with the patient's care team.
