comparing surgery case loads during two periods
Posted: Thu Mar 23, 2023 5:28 pm
Hi all,
Potentially silly question I'm hoping to get some insight on regarding how to compare trends in procedure volume in two different time periods. Essentially I have around 4500 cases(patients) for people who underwent the surgery of interest either in time period A or time period B. While I think I have a handle on comparing differences such as length of stay, hospitalization cost, etc., between the two time periods, I'm not sure how to statistically compare the changes in overall surgical volume between the two time periods.
In other words, there were ~22% fewer cases in period B than period A, and while I'm guessing that's a statistically significant decline, I don't know how exactly to test that.
Thanks for any help, I feel like this should be really straight forward but I'm struggling to grapple with this for whatever reason.
best,
Xavier
