Health is important to everyone. For most people, that means that understanding the healthcare system is important. As a patient or a caregiver for a loved one, your understanding of the system can mean everything from getting the right help, to economic stress in paying medical bills, to medical misadventures and even worse. And if you’re a healthcare professional (or are in training or want to be a healthcare professional someday), understanding the system is a critical – but often under-developed – part of optimizing the help you can provide your community.
