Linkage of Hospital Records and Death Certificates by a Search Engine and Machine Learning.
Vital status is of central importance to hospital clinical research. However, hospital information systems record only in-hospital death information.

The objective of this study was to link French death certificates to the Bordeaux University Hospital records to complete the vital status information.
