Objectivity and Reproducibility of Probabilistic Record Linkage.

Music City Center 

There has been tremendous research on the consolidation of health and medical data over the years, and researchers continue to explore the efficient way of consolidating and validating fragmented health and medical data to improve the service provided and better understand all other analyses. The two main approaches for record linkage are deterministic and probabilistic linkage. Probabilistic linkage has more advantages over the deterministic approach. However, subjective decisions are made when probabilistic linkage is applied. The data was generated with 20% noise input in the source dataset to support our proposed method. We showed an approach to selecting the optimal matching score for a match. Our results indicate an increase in the matching rate with an improvement in sensitivity, specificity, and precision.
