Screening for preclinical disease is effective only when early diagnosis and treatment improve outcomes. Health packages must prioritize proven early detection methods to maximize benefits and minimize screening hazards.

Area of Science:

  • Preventive Medicine
  • Public Health
  • Epidemiology

Background:

  • The core principle of preclinical disease screening is that early diagnosis and intervention yield better health outcomes than delayed treatment.
  • However, this principle is validated for a limited number of diseases in practice.
  • Screening programs must be evidence-based to ensure efficacy and safety.

Purpose of the Study:

  • To emphasize the necessity of developing early detection strategies based on proven effectiveness.
  • To advocate for the revision and adaptation of existing screening programs according to international standards.
  • To ensure that early detection maximizes health benefits while mitigating potential risks.

Main Methods:

  • Review of the theoretical basis for preclinical disease screening.

  • Analysis of the practical application and limitations of current screening programs.
  • Consideration of factors influencing the effectiveness of early detection, including disease incidence, prevalence, and population compliance.

    • Main Results:

    • A small fraction of diseases benefit from screening based on improved outcomes.
    • Effective early detection requires rigorous validation of methods.
    • Programmatic success hinges on adherence to guidelines and local adaptation.

    Conclusions:

    • Early detection strategies must be built upon demonstrated effectiveness.
    • Existing screening programs require updates aligned with global best practices.
    • Tailoring programs to local contexts and ensuring population engagement are crucial for realizing the advantages of early detection and avoiding screening-related harms.
