The National Ambulatory Medical Care Survey (NAMCS) is an annual survey of office-based physicians that gathers information about physicians and their practices through in-person interviews. A mail survey was conducted in 2011 on supplemental physician samples to allow for state-level estimates regarding physicians' use of electronic medical record/electronic health records (EMR/EHR). Each physician in the mail survey was sent questionnaires at two week intervals and phone calls were attempted with non-respondents after the third mailing for a total of four data collection waves. Because weighted and unweighted response rates for 2011 were only 61 and 64 percent, respectively, the potential for non-response bias will be investigated. Evaluation of the effect of nonresponse is difficult for a complex survey like NAMCS EMR. The method of response rate comparison across subgroup and the m
