What is data mapping in healthcare?

Data mapping in healthcare refers specifically to the process of connecting data elements from one database to another. This is a crucial function in managing healthcare data because it allows for the integration and interoperability of different health information systems. As various databases and electronic health record (EHR) systems may use different formats or terminologies for similar data elements, data mapping ensures that data from one system can be accurately translated and utilized in another.

For example, when an organization switches EHR systems or needs to combine data from multiple sources for reporting or analysis, data mapping helps to match fields (like patient ID numbers, diagnosis codes, and medication records). This mapping process guarantees that all relevant data is not only transferred correctly but can also be interpreted appropriately across systems.

The other options represent important concepts in healthcare data management but do not define data mapping specifically. Creating graphical representations of health data pertains to data visualization, analyzing patient health outcomes involves evaluating data to understand patient care effectiveness, and ensuring data security and compliance relates to adhering to regulations like HIPAA but doesn't address the mapping of data between systems.
