Using electronic surveys to gather information on physician practises during a response to a local epidemic-Rhode Island, 2011

Background: Electronic invitations may improve physician response rates to participate in internet surveys administered by public health agencies. Methods: Following an increase in reported HIV/syphilis co-infection diagnoses among men-who-have-sex-with-men in Rhode Island, we invited the state's 700 adult primary care and emergency medicine physicians via e-mail to participate in an online, multiple choice survey covering their knowledge, attitudes, and practices regarding sexually transmitted diseases and HIV testing and prevention. Survey invitations were released in three waves over 28 days, triggered by declining daily response rates. Results: Among 53% (n = 372) who agreed to participate, 68% (n = 252) completed all questions. Response was higher among internal medicine physicians than either family medicine or emergency medicine physicians (63% vs. 20% and 19%, respectively; P<0.0001). Daily response rates were highest in the first 48 hours after sending a reminder e-mail. Conclusion: This approach supported the Rhode Island Department of Health in rapidly gathering useful physician practice information during an outbreak. Internet-based survey tools coupled with increased prevalence of mobile communication devices and social media could greatly decrease the time and cost of shoe-leather epidemiology.
