The World Health Organization (WHO) has published a report examining the risks and benefits of evidence-based screening. The report highlights the key elements of organised screening programmes, including identification of target populations, treatment, monitoring and evaluation.
Effective screening programmes can improve public health outcomes, reduce disease and disability, but new technologies such as biomarkers, new imagery techniques or smart technologies may lack a robust evidence base. It is also important to note the potential for commercially driven interests and supplier-induced demand.
The report states that care is needed when implementing a screening programme to ensure benefits and risks are evaluated thoroughly, before screening takes place.
