In every industrialized nation, the movement to reform health care has begun with stories about cruelty.

We look for medicine to be an orderly field of knowledge and procedure. But it is not. It is an imperfect science, an enterprise of constantly changing knowledge, uncertain information, fallible individuals, and at the same time lives on the line. There is science in what we do, yes, but also habit, intuition, and sometimes plain old guessing. The gap between what we know and what we aim for persists. And this gap complicates everything we do.

Just look at the list of who the lowest-paid people are. Pediatricians are at the bottom. You would also look at internists. You would look at psychiatrists. You would look at family physicians, HIV specialists. People who take care of chronic illnesses by seeing people carefully over time, those are the people who get the least money. The people who have the most are people like orthopedic surgeons, interventional cardiologists. And my point isn't that there is something wrong with heroism.

Better is possible. It does not take genius. It takes diligence. It takes moral clarity. It takes ingenuity. And above all, it takes a willingness to try.

A failure often does not have to be a failure at all. However, you have to be ready for it-will you admit when things go wrong? Will you take steps to set them right?-because the difference between triumph and defeat, you'll find, isn't about willingness to take risks. It's about mastery of rescue.

People who reach certain levels of frailty, more important than getting their mammogram, more important than getting their blood pressure tweaked, they're at high risk of falling. If they fall and break their hip, they not only die sooner, they die miserably.

The Affordable Care Act also offered protections that allow for preexisting conditions, as people know, that you're provided coverage and you can maintain steady coverage. And that's an important part of being able to stay in care and do better over the long run.
