Synthetic data is becoming an important resource in healthcare research. It is artificially generated information that reflects the patterns and characteristics of real-world data without exposing personal patient details. Researchers use synthetic data to overcome privacy concerns, improve access to information, and support the development of new healthcare technologies. As healthcare organizations collect large amounts of data, synthetic datasets provide a safer way to analyze trends, test systems, and conduct studies. Understanding the role of synthetic data helps researchers, healthcare providers, and technology developers explore new opportunities while maintaining patient confidentiality and supporting responsible data use.
