Artificial Intelligence (AI) is a data driven technology that helps to generate intelligent and smart machines that are highly capable of performing different tasks by analysing data without human intervention. This technology is able to identify the patterns and deliver automated insights by using data and algorithms. Hence, it becomes useful in various applications in healthcare like Health monitoring, Management of medical records, Digital consultations, Treatment designing etc. In spite of evident benefits of AI in healthcare, its usefulness in patient care is debatable. The merits and demerits AI use in healthcare are compiled together to seek its potential impact on healthcare system and thereby explore its controversy.
