Clinical databases are organized collections of patient information used in healthcare settings. They store data from various sources, including electronic health records, clinical trials, and patient surveys. This information helps healthcare professionals track patient outcomes, monitor disease trends, and improve treatment protocols. These databases are essential for research and public health initiatives. They enable researchers to analyze large sets of data to identify patterns and correlations, which can lead to new medical insights. Additionally, clinical databases support regulatory compliance and quality assurance in healthcare by providing a systematic way to manage patient information and outcomes.
