Informatics impact requires effective, scalable tools and standards-based infrastructure
Abstract
Our field of biomedical and health informatics frequently considers the question of the impact of our research and its application on discovery, care delivery, health, and health equity. In this editorial I highlight 5 papers that illustrate scalable tools and standards-based infrastructure. Such innovations are components of the essential foundation for realizing the impact of informatics. Two papers address the critical issue of privacy preservation in secondary use of electronic health record (EHR) data,1,2 while a third focuses on information retrieval for COVID-19-related questions.3 Two additional papers focus on data definitions, codified vocabularies, and other components that enable semantic interoperability and their particular role in the COVID-19 pandemic.4,5 Carrell et al describe the hiding in plain sight (HIPS) approach which replaces personally identifying information (PII) tagged by a deidentification system with resynthesized content with the intent of making it harder to detect unredacted PPI.1 They used 2000 representative clinical documents from each of 2 healthcare settings to generate 2 deidentified 100-document corpora (200 documents total) where PII tagged by a typical automated machine-learned tagger was replaced by HIPS resynthesized content with a 10% leaky PII rate. Two readers from the originating institution and 2 external readers conducted aggressive reidentification attacks to isolate leaked PII. Mean recall and precision, respectively,…
