Researchers from the University of Oxford have benchmarked artificial intelligence (AI) tools capable of automatically removing personal information from patient electronic health records (EHRs) in a key step toward enabling large-scale, confidential medical research.
As health care becomes digitized, the wealth of information stored in millions of electronic health records (EHRs) is providing a valuable resource. These routinely collected data are driving advances in research, education, and quality improvement. But the increasing interest in using EHRs to train AI models aimed at improving patient outcomes is raising questions over whether current de-identification methods are robust enough to fully protect patient privacy.
“Patient confidentiality is essential to building public trust in health care research,” said Dr. Rachel Kuo, NIHR Doctoral Research...
