Derivation and validation of a machine learning record linkage algorithm between emergency medical services and the emergency department.
Linking emergency medical services (EMS) electronic patient care reports (ePCRs) to emergency department (ED) records can provide clinicians access to vital information that can alter management. It can also create rich databases for research and quality improvement. Unfortunately, previous attempts at ePCR and ED record linkage have had limited success. In this study, we use supervised machine learning to derive and validate an automated record linkage algorithm between EMS ePCRs and ED records. ⋯ We were able to successfully derive and validate a record linkage algorithm from a single EMS ePCR provider to our hospital EMR.
