Insights

Offering Continuing Medical Education (CME) credit and a five-dollar bill significantly boosted physician survey response rates. This combined incentive effectively motivated both surgeons and non-surgeons to complete mailed questionnaires.

Area of Science:

  • Medical Education Research
  • Survey Methodology
  • Health Services Research

Background:

  • Physician surveys are crucial for research but often suffer from low response rates.
  • Mailed questionnaires present unique challenges in engaging busy medical professionals.
  • Effective strategies are needed to improve participation in physician surveys.

Purpose of the Study:

  • To evaluate the impact of Continuing Medical Education (CME) credit and a monetary incentive on physician survey response rates.
  • To determine if these incentives improve questionnaire completion rates among different physician specialties.
  • To assess the effectiveness of combined incentives in mailed survey research.

Main Methods:

  • A randomized study involving 1,314 non-surgeons and 264 vascular surgeons from the AMA database.
  • Two distinct mailings with combined CME credit and a five-dollar bill were sent to non-respondents.
  • Response and completion rates were compared before and after the incentive interventions.

Main Results:

  • For non-surgeons, response rates increased from 26.5% to 30.2% after incentives.
  • For surgeons, response rates increased from 39% to 32.7% after incentives.
  • The combined incentive proved effective in motivating participation across physician groups.

Conclusions:

  • Offering CME credit alongside a small monetary incentive is a successful strategy for increasing physician survey participation.
  • These combined incentives significantly enhance response and completion rates for mailed questionnaires.
  • The findings provide valuable insights for designing future physician-based research studies.
