I would also argue that it is possible to decrease the individual cost of equipment by increasing it's utilization. For example it common practice in European hospitals to run expensive equipment like MRI machines 24/7 to reduce the overall cost. 

It is also possible to increase human utilization by concentrating skills in facilities dedicated to a given specialism. This is been done to great efficiency in India and there are facilities dedicated to, for example eye surgery, or heart treatments. This has proven to be extremely useful in attracting the best specialists from all over the world, because they are guaranteed to have a high throughput of patients in their dedicated field. This allows the facilities to train up many more specialists as there is a constant utilization of their skills.
