Evidence-based practice (EBP) has changed the healthcare in a positive way. It has been leading lots of changes in policies and procedures throughout the health care field. There is new research flowing continuously which helps in changing and amending the existing policies and procedures. Both internal and external evidences affect the practice. There are levels of evidence based on ranking and reliability, and are as follows:

Level I: Experimental study, RCT (randomized control trials), with or without meta-analysis. Example: Tuskegee syphilis experiment.

Level II: Quasi-experiment study, combination of RCTs and quasi-experimental studies (with or without meta-analysis). Example: New order-entry system in hospital and its effects before and after the intervention.

Level III: Non-experimental study: combination of RCTs, quasi-experiment, and non-experimental studies (with or without meta-analysis). Example: Research study on long-term ecstasy use.

Level IV: Opinions based on scientific evidence by reputed agencies. Example: consensus panels, clinical practice guidelines.

Level V: Non-research evidence and experiential evidence. Example: Case report, literature reviews.
