Clinical research is research that either directly involves a particular person or group of people or uses materials from humans, such as their behavior or samples of their tissue, that can be linked to a particular living person. (The process of clinical research, however, protects personal data.)
The NIH definition of clinical research is:
- Patient-oriented research: This type of research involves a particular person or group of people or uses materials from humans. This research can include:
- Studies of mechanisms of human disease
- Studies of therapies or interventions for disease
- Clinical trials (see About clinical trials for more details)
- Studies to develop new technology related to disease
- Epidemiological and behavioral studies: These types of studies examine the distribution of disease, the factors that affect health, and how people make health-related decisions.
- Outcomes and health services research: These studies seek to identify the most effective and most efficient interventions, treatments, and services.
The NICHD is involved with all aspects of clinical research and supports studies without limitations based on age, disease or condition, or technical type of research.
