Each of the three approaches has an important role to play in disease prevention. Health promotion EPHO 4 is inextricably intertwined with disease prevention. A recent self-assessment of public health services in 41 of the 53 countries in the WHO European Region found that:.

As a result, a recommendation was made to ensure a balance in the three disease prevention approaches: primary vaccination and health promotion , secondary screening and early detection of disease and tertiary integrated patient-centred disease management.

It provides data to facilitate international comparisons on performance in primary care services. WHO supports countries with surveillance of diseases, risk factors and enhancing early detection of diseases. EPHO5: Disease prevention, including early detection of illness. A recent self-assessment of public health services in 41 of the 53 countries in the WHO European Region found that: Primary prevention: routine immunization programmes are established in some form in all countries, and in most cases are well developed and effective.

However, arrangements for delivery of vaccine programmes are under-developed in some countries, especially for minority populations. Some Commonwealth of Independent States have seen an increase in vaccine preventable diseases following the breakdown of services available in the Soviet era. Secondary prevention: routine screening for major forms of cancer now exists in many countries, but not in all of them. Screening programmes are not always evidence-based and systemic health checks for noncommunicable diseases are not routine in most countries.

Staff need training in evidence-based treatment and management approaches for noncommunicable diseases, and modern equipment. Cardiovascular diseases, cancers, chronic respiratory diseases and diabetes WHO supports countries with surveillance of diseases, risk factors and enhancing early detection of diseases.

Natural History of Diseases: Statistical Designs and Issues

Understanding the natural history of a disease is an important prerequisite for designing studies that assess the impact of interventions, both chemotherapeutic and environmental, on the initiation and expression of the condition. Identification of biomarkers that mark disease progression may provide important indicators for drug targets and surrogate outcomes for clinical trials. However, collecting and visualizing data on natural history is challenging in part because disease processes are complex and evolve in different chronological periods for different subjects. Various epidemiological designs are used to elucidate components of the natural history process.
