Clinical data standards are the rules and guidelines for collecting and sharing information about patient medical records and other important data associated with providing patient care. They help healthcare providers and researchers exchange information in a consistent and accurate manner to make sure the data can be used correctly and that patient care is safe. For example, they might define what types of information should be recorded in a patient's chart, how the data can be organized, or what should be done with the data after it's collected. Clinical data standards make sure that the data is consistent across different providers so that everyone can access the same information and make sure the right treatments are provided.
