1
Q

Explain the difference between primary, secondary and tertiary prevention?

A

Primary - prevent yourself from getting the disease in the first place e.g. Healthy eating, vaccination

Secondary - Detect disease and prevent it from getting worse e.g. Breast cancer screening

Tertiary - improve the quality of life and treat the symptoms of the disease you already have e.g. insulin therapy in T2DM, Bronchodilators in COPD

Q

Provide health-related examples of intervention, with explanations for each example as to why they may or may not be classified as need, demand or supply

A

cosmetic surgery - demand - it isn’t necessarily an intervention that people will 100% benefit from and it isn’t just provided to people automatically

Flu jab - supply - what is provided and not always what people ask for and some don’t 100% benefit from it

minimum unit pricing for alcohol - need - 100% benefit from this form of intervention and it’s not what people asked for and it isn’t provided on all types of alcohol
