Only those in our sample could access the Web site. We alternately assigned the participants to receive the survey by mail (n=221) or an email invitation to participate on the Internet (n=221). Non-respondents in the mail arm received up to three additional copies of the survey, while non-respondents in the Internet arm received up to three additional requests, including a final mailed copy. All participants in the Internet arm had an opportunity to request an emailed Portable Document Format (PDF) version. Results: The Internet arm demonstrated a lower response rate (99/221, 45{\%}) than the mail questionnaire arm (129/221, 58{\%}) (absolute difference 13{\%}, 95{\%} confidence interval 4{\%}-22{\%}, P<0.01). Conclusions: Our Internet-based survey to surgeons resulted in a significantly lower response rate than a traditional mailed survey. Researchers should not assume that the widespread availability and potential ease of Internet-based surveys will translate into higher response rates.
