The integrity of health information in Electronic Health Record (EHR) is critical to delivering evidence-based care and improving population health through research. EHR errors are observed on fundamental data elements such as height/weight, causing both biologically implausible and patient-level conflicting data. We used a nonparametric regression with a Gaussian moving window to systematically identify outliers on population and individual level from IBM Explorys Therapeutic Dataset. This framework proves effective in improving data quality of EHR.
