The correct answer is: To provide definitions and descriptions of data elements within a database

The purpose of a data dictionary in health information systems is to provide definitions and descriptions of data elements within a database. A data dictionary serves as a centralized repository that outlines what data is collected, how it is structured, and the format in which it is presented. This is essential for ensuring consistency in the use of data across different systems and departments, facilitating data sharing and understanding among various users such as healthcare providers, administrators, and IT personnel. A well-constructed data dictionary helps to clarify the meaning of various data elements and their relationships, making it easier for users to interpret data accurately. This is particularly important in health information systems, where precise definitions can directly impact patient care, billing processes, and compliance with regulations. By defining data elements, a data dictionary contributes to improved data quality and ensures that everyone involved has a clear understanding of the information being utilized.
