I am doing research on the evaluation of some public health interventions at the population level. The intervention already conducted before. Know I want to evaluate its effectiveness. Thus what is your suggestion?
Dear Tegenne;
Could you make your question a bit clear?
What kind of data do you have?
There are several options to use depending on your data
Thank you, Hamid! The data are time-series data for different outcomes.
NO NO
even if it was done before you need to consider different time period may be two or more
Yes, Tegene. I know a PhD student who conducted an interrupted time series analyses using retrospective cohort HIV data to evaluate multiple outcomes of HIV care continuum—I will inbox you the contact address.
Hi Tegene Legese Dadi , Yes you can.
However, it depends on 1) presence of public health intervention at a defined point in time 2) reasonable data points before and after the intervention, etc. Have a look on the following tutorial for beginners.
