Background: Clinician surveys provide critical information about many facets of health care, but are often challenging to implement. Our objective was to assess use by participants and non-participants of a prepaid gift card incentive that could be later reclaimed by the researchers if unused. Methods: Clinicians were recruited to participate in a mailed or online survey as part of a study to characterize women’s primary health care provider attitudes towards breast and cervical cancer screening guidelines and practices (n = 177).

Since some of the respondents did not redeem their gift cards, the cost of incentives was less than it might have been if we had provided a conditional incentive of $50 to responders after they had completed the survey. Conclusions: Redeemable online gift card codes may provide an effective way to motivate clinicians to participate in surveys
