Just over ten years ago, a pivotal piece of legislation, the HITECH Act, was created to motivate the implementation of electronic health records (EHR) and supporting technology. Today, with EHR adoption at more than 90 percent, we are facing the new challenge of generating real-world data at the quality, completeness and accuracy necessary for the most valuable applications across the healthcare ecosystem.
A major hurdle in surfacing real-word data comes from interpreting the complex clinical context and nuances within a patient’s health record. Due to their expertise, trained clinicians are best suited for this. However, as researchers seek data on rarer cohorts, statistical techniques like machine learning are helping to scale data curation efforts by humans. These same techniques are also emerging as valuable tools for researchers as they explore novel approaches to increase data quality and completeness, and to identify meaningful patterns in large sets of data. Together, these tools are proving essential for realizing the promise of real-world data.
