The purpose of the National CLAS Physician Survey was to understand the provision of culturally and linguistically appropriate services among office-based physicians. The National CLAS Physician Survey was a supplement to the National Ambulatory Medical Care Survey (NAMCS), which is a national probability sample survey of visits to office-based physicians. NAMCS is a component of the National Health Care Surveys that measured health care utilization across a variety of health care providers’ settings. NAMCS and the National CLAS Physician Survey were conducted by the National Center for Health Statistics (NCHS). The National CLAS Physician Survey public use file includes data from office-based physicians. No patient level data were collected. This documentation describes the public use micro-data file produced from data collected in the National CLAS Physician Survey.
