Screening to detect the presence of asymptomatic disease is an important component of health maintenance and can often be accomplished at any patient visit. Frame 4 developed criteria to consider when selecting a disease and test to use for screening:
• The condition must have a significant effect on the quality and quantity of life.
• Acceptable methods of treatment must be available.

• The condition must have an asymptomatic period during which detection and treatment significantly reduce morbidity and mortality.
• Treatment in the asymptomatic phase must yield a therapeutic result superior to that obtained by delaying treatment until symptoms appear.
• Tests that are acceptable to patients must be available at a reasonable cost to detect the condition in the asymptomatic period.
• The incidence of the condition must be sufficient to justify the cost of screening.
• Test sensitivity, specificity, and positive predictive value are important factors in the selection and evaluation of screening tests.

Poor sensitivity or specificity can lead to a high rate of false-positive and false-negative results, both of which carry potentially serious consequences for patients.
Childrens For those older adults aged 45 to 64, cancer is the primary cause of death, followed next by heart disease, and then by unintentional injuries. Deaths in adults aged 65 and older resemble those for the overall population.
As the population ages, however, it seems apparent that those over the age of 65 are not a homogeneous group either. Recognize that the “young elderly” do not always fit the stereotypical profile of a geriatric patient and that the “older elderly” may have additional concerns that do not always apply to their younger peers. Patients should be viewed as a continuum rather than a series of distinct groups.
