What's the variablility you're trying to model: variability in
the patient's risk of complications or variability in the
physician's case mix? Indirect standardization is set up to
handle the latter. Is this what you really want? You're going to
have to be clearer about the hypothesis that you're testing.
You didn't ask, but I would be surprised if you got exactly what
you expected out of complication data. They tend to be poorly
collected so it's hard to eliminate the influence of differential
coding practices.
