Purpose: Patients with communication impairments including speech, language, cognition, or hearing disorders face many barriers to communication in health care settings. These patients report loss of autonomy in health care decision making, are at increased risk for medical errors, and are less satisfied with health care than patients without communication disorders. Although medical students receive training in effective patient-provider communication, most of this training assumes patients have intact communication abilities. Medical students and other health care providers are often unprepared to meet the communication needs of patients with communication disorders in health care encounters. The purpose of this study was to assess the impact of a curriculum for training medical students to communicate effectively with patients who have a range of communication disorders.
