Accurately and consistently matching patient data records is critical to ensuring safe and effective care to patients, preventing incorrect treatment and diagnosis decisions. The Patient Demographic Data Quality (PDDQ) Framework was derived from the Data Management Maturity Model by CMMI Institute, commissioned by Health and Human Services, Office of the National Controller for Health IT. The PDDQ helps organizations ensure that formulation, agreements, approvals, and implementation of standards and processes will be effective and sustainable, supporting the minimization of the number of duplicate records across the industry, ultimately improving patient safety.
