Healthcare Chatbots and Virtual Assistants

Abstract

Healthcare chatbots and virtual assistants are transforming patient care by integrating artificial intelligence (AI) and automation into healthcare systems. Chatbots act as interactive text conversational agents, whereas virtual assistants are more sophisticated, enabling voice interaction and personalized healthcare assistance. These technologies help to improve patient engagement, access to information, and administrative efficiency. AI, machine learning, natural language processing (NLP), and voice recognition play a critical role in helping chatbots and virtual assistants understand and respond to patient needs. Due to their integration with Electronic Health Records (EHRs), these tools are also used in a variety of specializations that allow for seamless communication, personalized symptom checkers, medication management, mental health support, chronic disease management, and even diagnostic assistance. They also enable telemedicine visits and clinical decision support, streamlining the healthcare experience. Despite their potential, challenges remain, including the accuracy of medical information and the need for continuous learning. This chapter discusses the different types of healthcare chatbots and virtual assistants and their applications and technologies; it also highlights the limitations involved in their use.
