Health Outcome Variation 

Even after accounting for patient's severity of illness and population demographics, there are significant variations in hospital outcomes. What are some of the actions that can be taken in order to reduce the outcome variation? Provide at least one example of a policy (state or national level) in recent history (passed in the last 15 years) which was introduced to reduce these variations. Provide a brief history of the policy and a brief summary of it, as well as key aspects of the policy.
