The healthcare industry is changing, with a greater dependence on technology, as seen by the incorporation of chatbots powered by artificial intelligence. Chatbots serve as virtual assistants, improving patient assistance, education, and engagement by providing information on medical issues and easing administrative procedures. Chatbots are particularly useful in symptom evaluation and telemedicine, allowing for virtual consultations and remote patient monitoring. Although chatbot technology is highly innovative and useful for medical and management professionals, the literature is still scarce and highly fragmented among different research areas. This chapter aims to analyze the power of chatbots in healthcare through scientific literature, providing a holistic understanding of the state of the art and future applications of chatbots. Despite acknowledged limitations, the substantial advantages hint at a positive outlook for their ongoing growth and integration into the healthcare ecosystem.
