400 eligible primary care providers (PCPs) will be recruited across the 7 participating sites to complete an anonymous survey. The survey will be distributed to eligible PCPs by the study site research coordinator via anonymous REDCap internet survey with 2 additional automated electronic reminders. There will also be opportunities for providers to complete a paper survey at PCP clinic meetings which will be collected by only the site research coordinator to maintain response anonymity.

100 eligible gastroenterologists (GIs) will be recruited across the 7 participating sites to complete an anonymous survey. The survey will be distributed to eligible GIs by the study site research coordinator via anonymous REDCap internet survey with 2 additional automated electronic reminders. There will also be opportunities for GIs to complete a paper survey at provider clinic meetings which will be collected by only the site research coordinator to maintain response anonymity.

500 eligible patients will be recruited across the 7 participating sites to complete a survey. The survey will be distributed to eligible patients at the time of a clinic appointment, via telephone, or via a REDCap internet survey that will allow for 2 additional electronic phone call reminders and 1 email reminder.

To assess PCP demographics, attitudes, and perceived barriers to BE screening, we have developed a PCP survey using a theoretical model of physician behavior based on Social Cognitive Theory and the Theory of Reasoned Action. This approach has proven effective in colorectal cancer and hepatocellular carcinoma screening. This model includes domains of provider background and experience, screening practices, perceptions of screening, physician influences, and practice environment and practice patterns. To assess PCP knowledge of BE screening, we have designed 9 clinical vignettes that will categorize provider responses into under-, appropriate, and over-use of BE screening. Survey questions and vignettes have been adapted from earlier validated surveys. Prior to distribution, the survey and vignettes will be pretested and refined based on a cognitive interview about the survey among a convenience sample of 10 PCPs.

This investigator will conduct a survey study among primary care providers and gastroenterologists at 7 large health systems in the U.S.-including 4 tertiary care referral centers and 3 safety-net health systems. Based on constructs from Social Cognitive Theory and Theory of Reasoned Action, the survey will assess provider knowledge, attitudes, and barriers to BE screening among at-risk individuals.

This investigator will conduct a survey study among patients at 7 large health systems in the U.S. Based on constructs from the Health Behavior Framework, the survey will assess patient knowledge, attitudes, and barriers to BE screening. To accomplish these study aims, this investigator has assembled a strong and diverse team with complementary areas of expertise in Barrett's esophagus, and survey research.
