Selected Research

Electronic health record usability and safety

With funding from the Agency for Healthcare Research and Quality and the Pew Charitable Trusts, Dr. Ratwani has led several studies focused on identifying usability and safety challenges associated with electronic health records (EHRs) and analyzing the effectiveness of federal policies on EHR usability. This work has been published in Health Affairs and JAMA.

Digital Health Utilization

Dr. Ratwani has led research analyzing how patients use different types of digital health (e.g., telehealth, chatbots) and study variability by patient demographics. This work has led to a deeper understanding of engaging different patient populations effectively.

Patient Safety Event Report Analytics

In this work, Dr. Ratwani has developed machine learning models to support more effective analysis of large databases of patient safety event reports. Applying machine learning and natural language processing to thousands of patient safety event reports has supported identifying critical safety signals.
