This is a good question. I would give a few pieces of advice.
First, I would want to see if all that can be automated is automated. For example, patient history, medical billing, and things like this should be on a database. This will allow for efficiency, and it will also cut costs.
Second, I would also make sure that the right people are hired and more importantly doing the right things. I would want to make sure that there are no redundancies in the process.
Finally, I would make sure that customer satisfaction is great as well. There is little point is being efficient, if customers are not happy.
