Health care analytics aims to improve clinical care while limiting excessive spending through analyzing claims and cost data, research and development data, clinical data from electronic medical records, and patient behavior data. Analytics can help health care organizations understand patients, develop personalized treatment plans, detect fraud, and reduce administrative costs. However, challenges include protecting privacy, establishing standards, and ensuring safe and ethical use of health data and technologies. Future trends include increased adoption of cloud solutions, use of IoT and streaming data, and implementation of big data and blockchain technologies.
