What are the best study materials to learn more about healthcare industry/problems in medicine/etc.

Does anyone have any recommendations for condensed study guides or short books (i.e. please do not link general websites with thousands of links) for interviews to prepare for healthcare industry/biggest problems in medicine/life of a physician/Medicare/Medicaid/ACA/healthcare policy? I have already read The Healthcare Handbook by Askin. Thank you.
