Hello,
Can anybody help to understand how can I calculate the risk-adjusted length of stay (LOS), I have los which is a continuous variable counted in number of days, I want to calculate adjusted Los of stay between group A and group B. the idea is that group B is sicker cohort than A that's why group B has higher in-patient stay in terms of numbers of days? however, is it possible that once adjusted for differences in characteristics of the two groups, the Los is similar between both groups? I have tried using predict estimation post Poisson model but this has failed to yield my desired results? any help would be appreciated I am happy to share the code or data if that's essential. but I feel this more sort of a general question instead of a coding issue.
