Targeting all individuals with the aim of reducing the risk for everyone. It recognises that the low risk majority may contribute a lot of cases and it reduces social inequalities.
288
What is the high risk approach to prevention?
Targeting only the individuals who are a high risk. It is accepted by society - treating those outside 'normal levels' and it is cheaper than the population approach.
289
What are the disadvantages of the high risk prevention approach?

- It can be difficult to identify those who are at high risk.
290

| - Public concerns over treating well people unnecessarily.
291

311
Categorical imperatives are a version of deontology. What are they?
A categorical imperative is a rule that is true in all circumstances. You should act in such a way that you would be willing for it to become universal law that everyone follows in the same situation.
312
What are the challenges of deontology?
Consequences aren't looked at. Duties can conflict.

| 2. Under 16, are they gillick competent?
327
A gentleman has made some nonspecific arrangements about his end-of-life management. His health deteriorates and the managing team consult family in making care-related decisions. According to the mental capacity act, why should family be consulted?
Family may be able to help the managing team better aware of the patient’s values and preferences when they have capacity. It can help with care-related decisions.
328
You are a medical student on a ward and you are concerned about the way one of the doctors is treating a patient. He tells you to examine the patient’s abdomen, but fails to ask for her consent. Which of the 4 ethical principles is being compromised here?
Autonomy is being compromised - the doctor is not respecting the patients decision. In this situation you would ask the patient for consent before carrying out the examination.
329
One of your fellow medical students turns up to ward rounds smelling of alcohol and you are concerned about their fitness to practice. Explain your course of action using the principle of deontology.
The duties of a doctor is a deontological document. Deontology is about the worthiness of the act. Turning up to work drunk is putting patients at risk; you are not protecting the health of patients and won't be able to provide a good standard of care.
330
You are walking home one day and a lady recognises that you are a doctor. She comes over to you and says you’ve recently been treating one of her neighbours and she wants to know how he is. She asks if you can tell her anything about his condition as she is really worried. What is your course of action?
You listen to the lady and understand her concern. However you can not tell her anything and you can not even reassure her as this would be breaking confidentiality. You could advise the lady to contact her neighbour herself and you apologise that there isn't anything you are able to say.
331
Can you think of reasons why you may not mind if the test is not particularly sensitive?
This may be acceptable where the consequences of missing the disease are minimal e.g. a disease with slow progression where delayed diagnosis was of no concern. Often screening tests with regular rounds e.g. when people are screened every 3 years have low sensitivity.
332
Why would a screening service look at improving the specificity of a test?
When the follow up diagnostic test is expensive or carries some risk so you want to minimise the number of disease free people having unnecessary procedures. Minimising False Positives may also be desirable where significant anxiety may be caused by a positive test result, or where there is significant stigma associated with the disease for which you are screening.
333
Can you think of reasons why you may not mind if the test is not particularly specific?
This may be acceptable where the condition creates little anxiety, and the follow on diagnostic testing is quick, cheap and safe.
334
What are deductive ethical arguments?
Using one general ethical theory and applying it to all medical problems.
335
What are inductive ethical arguments?
Using settled medical cases to generate theories or guides to medical practice.

1. Unhealthy food tends to be cheaper.
| 2. There is more advertising for unhealthy food because it is produced by large manufacturers.
