Dear Community,
Hopefully, an easy question to answer! Thanks for picking up this thread. I'm doing an evaluation on whether the use of a digital health tool (MyHealth app) changes the utilisation of healthcare services and am stumped on how to do the analysis. We have 4 groups, based on usage of the app: low, medium, high and a control group.
Hypothesis: patients who used the MyHealth app miss fewer hospital appointments / the more patients use the MyHealth app, the less likely they are to miss hospital appointments
I have data for a 12-month period in the following format as mocked-up in the table below:
I've also got aggregated data in this format:
Is there a statistical test that can tell me if there is a significant difference in the 4 groups rate of missed hospital appointments? Or do I need to do a test on the raw data (table 1)? I think a poisson regression might be in order but I can't figure out the periodicity e.g. if I need to take averages of hospital appointments over a time frame e.g. units of months.
Thank you so much for any and all help!
