CODI data models

The CODI data models are an extension of the National Patient-Centered Clinical Research Network’s (PCORnet) Common Data Model (CDM), a standard data model representing anonymized patient-level data for research. CODI augments the PCORnet CDM with a representation of chronic disease prevention programs and individual-level program participation data. Researchers can use CODI to access anonymized longitudinal record data for individuals that includes both clinical history and local public health program data.8 The Implementation Guide provides details on both data models.

RECORD LINKAGE DATA MODEL (RLDM)

Defines the data tables and data elements needed to perform the Privacy Preserving Record Linkage (PPRL) process. The model includes two tables from PCORnet CDM designed to contain unencrypted personal identifiable information (PII). These two tables must be implemented by a data owner or partner in a secure repository.

RESEARCH DATA MODEL (RDM)

Provides the data tables and data elements needed to answer selected chronic disease research and program evaluation questions.
