I'm working on a quality improvement proposal where I am developing a plan to improve childhood immunization compliance in a rural public school setting. I will use previous years state reports on compliance with our school, and use that same process/data to measure the success of the changes my proposal plans implement. There is no randomization or informed consent needed. The results will include all students from pre-K-grade 12, which is 1200 students. I am unsure how to proceed on this question: "Identification of variables, hypothesis test, and statistical test needed to prove the quality improvement succeeded and are accurate. The proposed elements will prove whether the QI succeeded." Thank you for your assistance.
