Hi, friend! I am very interested in the staggered randomized or stepped wedge design you mentioned before. Could you please let me know more about it?

Hi, friend! I know that the most rigorous and credible way to develop a counterfactual is to randomize practices interested in participating in the intervention to an intervention or control group. The control group will then provide a good proxy of what would have happened to intervention practices had they not adopted the model. However, our team all believes that we cannot conduct a randomized trial for ethical and also fairness reasons. In such cases, may I ask if there is any possible solution?

Hi, friend! May I ask why should evaluators need to make sure comparison practices are as similar as possible to intervention practices before the intervention begins?

Thanks for your previous information. I wonder if, I mean “if”, I get huge funding for supporting my program evaluation. Lots of doctors and nurses would come to my support. Then how can I design the data collection?
