National Electronic Health Records Survey
The National Electronic Health Records Survey (NEHRS) is an annual survey of non-federally employed, office-based physicians practicing in the United States (excluding those in the specialties of anesthesiology, radiology, and pathology). NEHRS began in 2008 and was originally designed as an annual mail supplement to the National Ambulatory Medical Care Survey (NAMCS). Starting in 2010, funding permitted an increase in the sample size to allow measurement of electronic health record (EHR) adoption rates by all 50 U.S. states and the District of Columbia. Since 2012, NEHRS has been administered as a survey independent of NAMCS, using data collection through web, postal mail, and telephone.
NEHRS is conducted by the National Center for Health Statistics (NCHS) and sponsored by the Office of the National Coordinator for Health Information Technology (ONC).
Data from NEHRS can be used to produce state and national estimates of EHR adoption and capabilities, burden associated with EHRs, and progress physicians have made towards meeting the policy goals of the HITECH Act. In more recent years, survey questions have also asked about the Promoting Interoperability programs, sponsored by the Centers for Medicare and Medicaid Services (CMS).
Using NEHRS data, NCHS publishes summary web tables to describe the general frequencies of EHR adoption. Data from NEHRS have also been used by researchers in reports such as Health United States, Healthy People 2020, and various additional reports and research from the federal, public, and international communities.
To access any restricted NEHRS data from 2008-2015, and 2017 onward, investigators must first write a research proposal to the NCHS Research Data Center (RDC). Instructions for preparing and submitting an RDC proposal are available here.
