efficacy  

Definition

  • Efficacy is the extent to which a particular health technology (medical device, drug, procedure, health program, or health service, including interventions) does what it is intended to do (i.e., a beneficial health outcome or result) under ideal conditions. For instance, clinical trials, which are conducted with a selected population and during which subjects may be monitored more closely than they would be in a clinical practice, can establish the efficacy of a health technology.
