National Health Data Dictionary

The National Health Data Dictionary is a standardized collection of terms, definitions, and structures used to organize and record health information consistently across healthcare systems. It ensures that healthcare providers, researchers, and policymakers use the same language when describing health data, such as patient diagnoses, treatments, and outcomes. This consistency improves data quality, comparability, and analysis, supporting better decision-making and healthcare delivery. Essentially, it acts as a common reference guide that helps organize complex health information in a clear, uniform way.
