For clinical survey design and IRB submission, we have to go through the following steps:

1. Find topic and search literature (see attached)
2. Get idea for hypothesis and write the outline for Background and Objectives
3. Design clinical survey
4. Generate survey questionnaire
5. Process IRB submission
