Reducing the Risk of Blood Clots in Hospital

This leaflet will explain how we try to reduce the risk of you having a blood clot after you have been admitted to hospital.

If you have a blood clot in your leg, it is called deep vein thrombosis (DVT). If you have a blood a clot in your lung, it is called pulmonary embolus (PE).

Why might I have a blood clot?

Being unwell can cause you to be less active. This can cause blood flow through your body and veins to be slower, which can increase your risk of developing a blood clot.

The illness you are suffering from can also make your blood more prone to clotting. The combination of being less mobile and your blood being more likely to clotting will increase your risk of having a blood clot.

If you are admitted to hospital for a planned operation or procedure, you can become more likely to developing blood clots. Many patients are less mobile after having their operation or procedure. As you recover from this, your blood is more likely to develop clots.

Are blood clots serious?

Yes, they can be. A DVT can cause severe pain and swelling in your leg. It can make you less able to walk and slow down your recovery. If you have a DVT, this can cause long-term damage to the veins in your leg. This can lead to persistent swelling and pain in your leg.

A clot can break off, travel up to your heart, and pass to your lungs where it becomes a PE. A PE can cause severe chest pain, breathlessness and, in a small number of cases, death.

A PE can also greatly slow down your recovery from other medical conditions.

How will I know if I am at high risk of developing blood clots?

Your medical team will complete an assessment when you are admitted to hospital. This will assess your risk factors for developing blood clots, and if it is likely that your mobility will be effected during your admission.

The medical team will also check to see if any other treatment may need to be considered in order to reduce your risk of developing blood clots.

How will you reduce my chances of having a blood clot?

There are several ways we can try to reduce your risk of developing blood clots. These include:

Blood-thinning injections

The most common way to reduce your chance of having a blood clot is by giving you small dose injection of a blood thinning medicine each day. The medicines we use are Tinzaparin or Enoxaparin. The injection is given under the skin in the stomach.

It is safe and usually painless. There is a very small risk of having an allergic reaction. You may also develop some bruises at the site of the injections. These bruises will heal without any problem.

TED (Thrombo Embolic Device) stockings or Anti-Embolism stockings

These are tight fitting stockings, worn on your legs during the day. These stockings help to improve the flow of blood through the veins in your legs, reducing the chance of a blood clot to form. They are worn all day and are to be taken off when you go to bed.

TED stockings are safe to use for most people. However, we do not give them to you if you have suffered a stroke, have circulation problems or have swollen legs.

Other ways to reduce the risk of blood clots

For patients who are not suitable for either of the above, we do use pneumatic compression boots. These coverings go over your calves and are attached to an air pump. The pump inflates and deflates the covering around your calves. This acts to squeeze the blood through your legs and keep the blood flowing well.

If you are already taking a blood thinning medication, such as warfarin, apixaban, or any other blood thinning medicine, you will usually continue taking this, without being given any of the medication mentioned above.

What can I do to help to stop blood clots forming while I am in hospital and when I go home?

You can reduce the risk of blood clots forming by doing some simple things:

• Keep well hydrated – Drink regularly and stay as well hydrated as you can (unless there is a reason that the medical team are limiting your fluid intake).

• Exercise – This can be as simple as regular movements while you are in bed. If you are able to take regular walks around your bed space or out into the ward area, this will help.

• Complete all your treatment as prescribed – If you stop any of your treatment earlier than recommended, this can cause the problem to come back. This would slow down your recovery and increase your risk of developing a blood clot.

• Stop smoking – Smoking causes your blood to clot more easily. Stopping smoking, even for a short time while in hospital, can reduce the risk of blood clots forming. You can ask to be given nicotine replacement patches that can help you do this while you are in hospital.

Will I need any further treatment when I arrive home?

It is unusual for patients to require further treatment. However, if you have had surgical or orthopaedic operations or if you have given birth recently, you may be given treatment following your return to your home.
