Evidence-based practice is patient care based on research. It helps medical practitioners to make practical decisions based on the best available evidence. There are two types of sources you would want to look for: systematic reviews and clinical trials.
Primary Sources:
- Clinical trials
"A type of research study that tests how well new medical approaches work in people. These studies test new methods of screening, prevention, diagnosis, or treatment of a disease." -PubMed Health
- Randomized Control Trials
"A study in which the participants are assigned by chance to separate groups; neither the researchers nor the participants can choose which group." -PubMed Health
Secondary Sources:
- Systematic reviews critically assess and review research studies of a particular clinical issue.
"A systematic review is a research study that collects and looks at multiple studies. Researchers use methods that are determined before they begin to frame one or more questions, then find and analyze the studies that relate to that question." -PubMed Health
