poisson multilevel model after multiple imputation

I have carried out a multiple imputation in R using Amelia II and have created 5 multiply imputed datasets. The purpose of my research is to fit a Poisson Multilevel Model to the data to estimate numbers of hospital admissions.
Now that I have 5 completed datasets, how do I go about fitting the multilevel model? How do I pool all the 5 datasets to get one final multilevel/mixed model?

Can anyone PLEASE guide me?!

Many thanks and regards...
