Dear all,

I wonder if anyone has come across this issue?

I'm calculating directly age/sex standardised hospital admission rates for 
sub-national areas, using national totals as the standard population. Since 
individuals can have multiple admissions, it seems that the usual methods 
for calculating confidence intervals (I usually use -dstdize-) are not 
appropriate, due to extra-Poisson variation.

I've found references to methods that account for this, neatly summarised 
here: <http://www.doh.wa.gov/Data/Guidelines/ConfIntguide.htm#tth_sEc4.6>

I'm having trouble figuring out exactly how to implement these methods in 
Stata, and just wondering if anyone has dealt with this issue and has a 
sample do file that I might be able to adapt? Or an alternative method?

Thanks a lot
Ben
