A common use of entity resolution in healthcare is to help improve patient care by linking together data from multiple sources, such as electronic health records, lab results, and prescription information. This can help healthcare providers better understand a patient's health history and provide more informed care.

​

Entity resolution can also be used to improve the efficiency of healthcare operations by helping to identify and track patients with similar symptoms or diseases, and reduce administrative burden.

​

Furthermore, it is used to identify and monitor healthcare organisations, key influencers, publishers, research developments, and competitors.
