Glossary of Terms

We know that many of the concepts used on this site can be difficult to understand. For that reason, we have provided you with a glossary to help you make sense of the terms used in Comparative Effectiveness Research. Every word that is defined in this glossary should appear highlighted throughout the Web site. When you come upon a highlighted term and would like to read the full definition, you can either click on the word to visit the glossary or roll your mouse over the word for a pop-up definition.

Outcome

Definition: The end result of health care practices. There are many kinds of outcomes. How long people live following a health care treatment is one kind of outcome, known as survival. Other outcomes measure the effects a treatment has on people’s lives, such as changes in their ability to function or changes in their quality of life. Outcomes also include undesirable events such as side effects of drugs. Another type of outcome is whether people needed to change to another kind of treatment.

Example: Researchers studied the outcomes of treatment for coronary artery disease. They examined how long people lived after the treatments. They also examined how many people had chest pain or heart attacks after the treatments.
