Accuracy of privacy preserving record linkage for real world data in the United States: a systemic review.

ABSTRACT:

Objectives

Examine the accuracy of privacy preserving record linkage (PPRL) matches in real world data (RWD).

Materials and methods

We conducted a systematic literature review to identify articles evaluating PPRL methods from January 1, 2013 to June 15, 2023. Eligible studies included original research reporting quantitative metrics such as precision and recall in health-related data sources. Covidence software was used to manage the review process.

Results

Five studies met our inclusion criteria. Tokenization and hash functions were used to hash and encrypt personally identifiable information (PII) including first and last names, dates of birth (DOB), and Social Security Numbers (SSNs) in a variety of RWD. All identified studies utilized deterministic matching. Combi
