Expressing the Yield of a Screening Test Number Needed to Screen

"Number needed to screen" is a concept used to express the number of individuals who would need to be screened for a disease to prevent a single complication (morbidity or mortality) of that disease. The "number needed to treat" is a corollary concept that may be used for preventive medications (e.g., aspirin therapy). The number needed to treat is the number of individuals who would need to undergo the treatment or intervention to prevent a single case of disease (e.g., heart disease). This type of statistic may be useful for clinicians and patients when prioritizing different prevention or treatment options.
