How to calculate predictive value?

Hi everybody,

I'm a doctor working in a hospital somewhere and I'm doing an audit on my ward. I want to know if certain variables (i.e. diagnosis, ethnicity, DOB, etc.) OR a combination of certain variables has any predictive value in predicting patient's length of hospital stay.

I have a large dataset to look at.

How would you go about doing this?

Multiple linear regression could be used to build a model with diagnosis, ethnicity, DOB etc.
as predictors, and length of stay as dependent variable.

With kind regards
