Improving Health Care Quality

A Guide for Patients and Families

This guide presents information and lists resources to help you get better quality health care. You can read all the way through or go directly to the sections that interest you the most:

Every day, millions of Americans receive high-quality health care. They get the right care, at the right time, and in the right way. And, they get the best possible results.

But every once in a while, something goes wrong. People receive health care services they don't need. Or they can't get care when they need it. Sometimes, people are affected by medical errors that could have been prevented. A medical error is a mistake that happens when a person gets health care services.

The fact is, health care quality varies. There are many reasons for this because quality depends on many things, including where you live, who you are, and how much is known about treating your condition.
