Document Summary
Process of evaluating population for asymptomatic disease or risk factors associated with the development of disease/injury. In community setting applied population (residents, students, workers) Positive screening test must be followed up by a diagnostic test. Healthy-seeming patients, with no perception of disease: greater risk of doing net harm via haphazard screening tests, higher standards should be set for screening than for actual therapeutic interventions. Process of searching for asymptomatic disease or risk factors in clinical setting. First time patients undergo history, physical exam and necessary laboratory tests. Screening: employees having an annual blood pressure check through a company program. Case finding: a patient undergoing an elective surgery has a chest x-ray. Test a large population sample from a community setting (education, work, recreational, etc. ) for one or multiple diseases or risk factors. Minimal or no direct financial cost to the patient. Disease: management to reduce mortality, to prevent complications/sequelae, to eradicate and prevent spread of infection, diet and lifestyle change.
