Making health choices

Sometimes it’s very clear that treatment is needed, fast.

• George

  George is walking down the street when he is suddenly run over by a car. He is knocked unconscious and is bleeding heavily. An ambulance is called and paramedics immediately start treating him with fluids into his veins and drugs to support his heart and lungs.

But sometimes it is much less clear - and more difficult to decide.

• Helen and Susan

  Helen and Susan have had their blood pressure checked and been told it is high. They are each recommended medication to lower their blood pressure. They are each on five other tablets already, and don't really want to take another one. Helen and Susan also know that having a high blood pressure increases the risk of a heart attack or stroke. Helen and Susan wonder what to do.

In many situations there are pros and cons which have to be weighed up. These depend on the circumstances and wishes of the person.

For example:

• Helen

  Helen has lung cancer which has spread. She knows that she is not likely to live for more than a year or two. She has decided that she wants a good quality of life and wants to avoid the change of side effects from treatment. Since the blood pressure tablets are designed to work to reduce the risk of heart attacks and strokes over years, she decides not to take them.

• Susan

  Susan’s parents had heart attacks. She has a type of arthritis which she knows increases her risk of a heart attack or stroke. She is very keen to try and reduce her risk as much as she can. She is already eating healthily, has stopped smoking, and exercises regularly. She decides that taking another tablet is worth it.

• Naz

  Naz has a chesty cough but is otherwise well. He wants to know if he really needs antibiotics. Guidelines from the National Institute of Health and Care Excellence (NICE) say that antibiotics are not needed if the person is otherwise well. He is just as likely to get better without them. Naz is right - he doesn’t need antibiotics. However - if he had taken them, he would get still have got better. That could make us think the antibiotics helped - when they didn’t.

People are different and can make different, but equally good, choices about their health

It’s usually a good idea to take some time to think about your options.

Your options will often include doing nothing - sometimes the treatment can be worse than the condition you have. Some people find thinking about their choices with a checklist helps, like this one 

There is also help available for some choices at NHS Right Care. Many people want to make sure that their healthcare professionals know about their choices. This can be done with a care plan.

You might be offered one or you can ask for one.

You might also be interested in guardianship or powers of attorney.

These are legal documents designed for people who are not able to make choices about their healthcare, either because of disability or illness. They try to make sure that healthcare staff know about your wishes.

Powers of attorney are created when you are well and able to say what you would like if you can’t make your own choices in the future. It’s better to have one and not need it rather than need one and not have it!

It’s never too early for adults to consider making a power of attorney.

Steve is 70 and is taking several medications for gout, hip arthritis, and chronic bronchitis. The pharmacy offered to check his blood pressure when he last went for his prescriptions. It was high and they have told him to see his doctor. He agreed to start medication for it - but he felt dizzy with the tablets and this is stopping him getting out for walks. He goes back to see his doctor. 
 
Steve wants to know if he really needs the tablets? His doctor tells him that they are recommended by guidelines. Steve asks his doctor how likely they are to help him, and wants to know if there are any alternatives?

• Balancing risks

  Making choices about treatment is often hard. People have to balance the potential for risks, harms, benefits, and side effects. We know that lowering blood pressure can help to avoid a heart attack or stroke. But it does not help everyone who takes it.

  • But not everyone who has high blood pressure will have a heart attack or a stroke

  • But some people who have high blood pressure will have a heart attack or a stroke

  • Taking medication can reduce the risk of having a heart attack or stroke

  • But not everyone who takes medication for their blood pressure will stop a heart attack or stroke from happening

  • It isn’t possible to predict which individual people with high blood pressure are going to have a heart attack or stroke

  • It isn’t possible to know which individual people taking blood pressure medication prevent a heart attack or stroke by taking the tablets

  • There are other tablets to treat blood pressure which might be better for Steve and could be tried

  • Blood pressure can also be lowered by exercise or a low salt diet

  And of course, maybe Steve's blood pressure is fine at home and he just gets high blood pressure when meeting health professionals (white coat syndrome).

Making good choices often means juggling many possibilities

There is a similar problem with tests - like blood tests or X-rays or CT scans.

Often the result is clear.

However, the result is often not clear - the blood test result may be slightly abnormal. Or a scan shows a small lump somewhere unexpected - and it’s not clear whether it is something worrying or not. As we get older we get more small abnormalities in our bodies - like cysts or warty skin growths - and the majority are benign - not cancer, and will not do us any serious harm.

This is one of the reasons why it’s important to carefully consider when to do tests, and when not to.

It can be hard to work out which are worrying abnormalities, and which are 'normal' abnormalities. This often means people have further tests or scans to see if they are worse or better. Rather than reassuring people, these further tests can cause more anxiety, or pain, or infection. Tests can end up doing more harm than good. If you are interested, there is more about that on the Conversation website. 

This is why doctors are taught to think before testing. People need reliable information before deciding to be tested too.

For example, coughing is a common symptom of lung cancer.

• Lung cancer

  But most people with coughs will not have lung cancer... they will have colds, or flu, or allergies. Very few p
