A re-sample study to assess whether there was measurable non-response bias in the 2003 Innovative Surgery study. The questionnaire used for this study was an exact replication of the original questionnaire. The instrument contained questions about surgeons' opinions concerning innovative or experimental surgery. Responses of the new respondents were compared to those who responded originally.
