Average patient visits based on age group and condition tags

It would be really useful to be able to see the average number of patient visits filtered by age group and/or filtered by condition/diagnosis/body area tags.

E.g. seeing the average patient visits for those 20's, 30's, 40's, 50's, 60's etc (before discharge or maintenance care) for their initial course of care.

Whilst every patient is different it gives an overview of results for each patient depending on their age group which could be shown to patients to see how they compare to their age group in terms of recovery times.
