Please write a memo. For this assignment, imagine that you are a doctor at a mid-sized community clinic. Dr. Peterson, a doctor in your practice, suggests creating an accountable care organization (ACO) with other hospitals and healthcare providers to provide quality healthcare to Medicare patients. The other doctors in the practice are not too sure about this, mostly because they don't understand what an ACO is and what function it serves. Since you are the most junior physician on the staff and just one year out of medical school, Dr. Peterson nominates you to write a memo to the other staff members that will address their concerns.
