There are LOTS of errors that can be made in a hospital. Fortunately, at every step of the way, there are people that can prevent it. In the Swiss Cheese Model (This is real!

This is especially relevant in medical training, where mistakes (harm to patients) are prevented by having series of residents, attendings, nurses, pharmacies, etc.
