Which is why in other countries, such as the UK, the NHS will look at the potential for preventing disease/extending QALY based on peer-reviewed evidence, the risks of harm and overall cost-effectiveness before then coming up with a model for the whole population when it comes to screening which targets patient demographics most likely to benefit. The following conditions are pro-actively screened in this way:
- Abdominal aortic aneurysm
- Bowel cancer
- Breast cancer
- Cervical cancer
- Diabetic eye screening
Patients with early symptoms of e.g. skin cancer can get moles checked out free of charge, and the yearly dental & vision check will screen for conditions like oral cancer and glaucoma.
The harm of something like a yearly colonoscopy in the general asymptomatic population would far exceed the potential benefits.
