how did this bacteria develop? is it only possible to get it in hospitals?

I'm having a hard time believing these health care facilities can't make their employees wash their hands, what is up with that? Haven't we known for several centuries that hand washing is one of the number one ways to prevent the spread of infection? 

Okay so employers can't make their employees wash their hands, how about if the patients make them? Is there anything wrong with asking the health care worker if they washed their hands after they saw their last patient? It might make them more accountable for their actions and it could save the patients life.
