Top 5 AI Use Cases in Health Care with CRISP-DM Framework

Artificial Intelligence (AI) is revolutionizing the healthcare industry by enabling more efficient, accurate, and personalized care. From predictive analytics that help prevent patient readmissions to advanced imaging diagnostics that enhance disease detection, AI is reshaping how healthcare providers approach patient treatment and care delivery. The integration of AI technologies into healthcare processes is guided by structured methodologies like the CRISP-DM (Cross-Industry Standard Process for Data Mining) framework, which ensures that AI solutions are developed systematically, from understanding business objectives to deploying models in real-world clinical environments. This framework facilitates the development of AI use cases that are not only innovative but also practical and impactful in improving patient outcomes and operational efficiency.
