Anticoagulation and thrombosis
What we do
We look after people who have had blood clots, also known as deep vein thromboses. These are common but can make people very unwell. They usually occur in the veins of the lungs (known as a pulmonary embolism) , legs, arms, brain or abdomen. Occasionally we will also look after people who have had blood clots in other places, for example in the heart, where we would work alongside the cardiology team.
We help the teams on the ward and in A&E decide what treatment to start, then we see patients in clinic and help decide how long treatment is needed, whether any tests are needed for an underlying cause, and what the best treatment is from that point onwards. We help educate and counsel patients about how to use their medicine for blood clots (anticoagulants) safely, and how to lower their risk of further clots in future. Sometimes you will speak to a doctor, and sometimes a nurse or pharmacist, depending on the type of decision or counselling that you need.
- We also help patients who have an irregular heart rhythm (atrial fibrillation) to start anticoagulants safely, after the decision to start this treatment has been made, usually by a GP, cardiologist or stroke doctor.
- If a decision is made to start you on warfarin you will be seen in the warfarin clinic.
- Our team is made up of doctors, nurses, pharmacists and scientists, and together we look after patients at the Royal London, St Bartholomew's, Newham and Whipps Cross hospitals, with lots of us working at more than one hospital.
What to expect in our warfarin clinic
You will receive a letter to invite you to a face-to-face clinic at either The Royal London, Whipps Cross, St Bartholomew's or Newham, depending on where you live.
We will explain how to take warfarin safely. You will have your first blood test and be told how much warfarin to take. This will be written in your yellow warfarin record. You will need regular blood tests in this clinic to determine what dose of warfarin you need. If you are housebound, we will try to arrange someone to come to your house to do the blood tests. If you are on dialysis we can do this through the dialysis unit. Some people prefer to buy self-testing kits at home, in which case we can use the blood tests you do yourself to dose your warfarin. Your GP will give you prescriptions for the warfarin tablets but the warfarin clinic will keep letting you know how much to take.

What to expect in our thrombosis clinic
If you have been diagnosed with a blood clot, also known as a deep vein thrombosis or pulmonary embolism, you will be given medicine called an anticoagulant to help your body heal and prevent another clot from forming when you are sent home from hospital. Unless advised specifically otherwise, please keep taking your medication until you are seen in thrombosis clinic, with extra prescriptions from your GP if needed.
You will receive a letter informing you of your appointment, which is likely to be by phone or video the first time, and is usually around 6 to 12 weeks after the clot happened. Please make sure your GP has your correct telephone number and address as we use your GP record to contact you. The doctor in clinic will go over your history and help you decide how long to take the anticoagulant, what the best type of anticoagulant is for you going forwards, whether there was an underlying cause for the blood clot that needs treatment, and what you can do to try to prevent another blood clot in future.
After an appointment you and your GP will receive a letter summarising what you discussed. If you need another appointment you will be sent another letter letting you know when it will be. Any new prescriptions will be issued from the hospital pharmacy. Sometimes you may need further tests like scans or blood tests.
Contact us to cancel or rearrange an appointment for thrombosis clinics, including if you would like to request a change to the format of the clinic (phone/ video/ face-to-face).

We look after patients who have been diagnosed with immune thrombocytopenia (ITP). ITP is rare and occurs in about 3-4 per 100,000 adults per year. It is an autoimmune condition defined by low platelet count (<100 x10^9/L) and may cause easy bruising or bleeding if the platelet count is very low (<50 x10^9L).
The ITP clinic at The Royal London Hospital is a specialist clinic. Once a diagnosis of ITP has been made, we provide treatment, if needed, and follow up patients in our haematology day unit and outpatient clinic. Treatment for ITP is individualised and not all patients with this condition require treatment.
In addition to caring for patients with ITP who live near our hospital, we are also a tertiary referral centre for complex patients from other hospitals in the region.
We also offer the opportunity to take part in clinical studies on the causes of or treatment of ITP where we feel this would be suitable.
What to expect in our clinic
We use a combination of face to face, video and telephone clinics. During your first consultation, which may be face to face or virtual, we will discuss your medical history, family history, medication use and review any investigations you have had to date.
Usually you will have to have further blood tests and sometimes other investigations which help us to make the diagnosis of ITP. These may include ultrasound scans or a bone marrow test.
Having completed our initial assessment, we will discuss what treatment options, if any, may be required for ITP. We may also discuss studies of new medications (clinical trials) that may be available to you and give you the opportunity to take part if you so wish.
During follow up appointments, we will monitor your blood test results and response to any treatment you are taking for ITP. Subsequent appointments may be virtual or face to face.
We also review patients on our haematology day unit (2nd floor, The Royal London hospital). Sometimes you may be asked to attend here for a blood test or to meet with a member of the team.
Occasionally you may need urgent treatment and this will be managed either on our haematology day care unit or by an admission to hospital.
What to expect after an appointment
After an appointment, you and your GP will receive a letter summarising what was discussed. If you need another appointment you will be sent another letter letting you know when it will be.

The clinical team can provide you with information about ITP and treatments when you are seen in the outpatient clinic.
The ITP Support Association has lots of useful information and support for patients and relatives, including information on Covid-19.
We also host the national registry for adult ITP. This is a study which aims to help us better understand the causes of ITP, responses to treatment and outcomes for patients. Your team will discuss this with you at your clinic appointment.
