About the team
Based at St Peter’s Hospital and Woking Community Hospital
We are an outpatient led service managing patients taking anticoagulant (blood-thinning) medication to prevent blood clots. The team provides monitoring of INR (International Normalised Ratio), adjust warfarin dosages, offer support and education on anticoagulation and manage conditions such as deep vein thrombosis (DVT) and atrial fibrillation (AF).

What we do
- Monitoring and management: Provide regular monitoring for patients, particularly those on warfarin, using blood tests, to ensure it is within the correct INR target range.
- Treatment adjustments: Advise on changes to anticoagulation medication dosage to maintain a safe and effective level of anticoagulation.
- Initiating treatment: Start new patients on anticoagulant therapy and manage conditions like AF, pulmonary embolism, and other thrombosis-related issues.
- Ongoing monitoring: for patients on warfarin we provide ongoing monitoring of INRs either with a Venus blood test or finger prick INR appointment and we advise on dosage and next appointment date.
How to access our service
- Referral: You will typically need a referral from your GP or another healthcare professional to attend the clinic.
- Inpatient or A&E: You may be referred after being admitted to the hospital or visiting the emergency department.
What can patient expect
- Appointments: You will have scheduled appointments to check your progress and receive advice on your anticoagulant. Some patients have their own anticoagulation machines at home where they monitor their own INR results and send to the team via email, where the information is logged and the patient receives their dose instruction and next due date for INR reading.
- Testing: Venus blood tests or INR finger prick tests are part of the appointment to monitor your International Normalised Ratio (INR) if you are on warfarin.
- Education: All new patient will receive information about your anticoagulation medication and how to manage your condition and an alert card to keep on your person.
Important advice for patients
An Anticoagulant delays your blood from clotting, Warfarin is an anticoagulant. Taking Warfarin is safe provided you follow the DO’s and DON’Ts.
A letter will be sent to your GP advising them that you have commenced Warfarin, the reason why and how long your treatment should last.
A blood test called an ‘INR’ is required to tell us how long Warfarin is delaying your blood from clotting. We will inform you by means of a dosage letter what the result of the INR is and what dose of Warfarin you must take. The letter will also advise you when your next blood test is due and provide a blood test request form.
Always carry your dosage letter with you and show it to your doctor dentist or any other medical practitioner, when obtaining treatment. Show it to your Pharmacist when you are having a prescription dispensed and when purchasing medicines ‘over the counter’ as a pharmacist can advise you if it is suitable.

Don'ts

| DON’T take an extra dose of anticoagulant if you are unsure if you have taken your tablets. | If necessary use a calendar and mark off each dose by a line through the date. |
| DON’T run out of tablets you can obtain a repeat prescription for Warfarin tablets from your GP. | Do not run out of tablets before the repeat prescription is requested |
| DON’T take aspirin or any preparation containing aspirin (acetylsalicylic acid) unless this is prescribed by a doctor who knows you are taking anticoagulants. | When buying any medicine over the counter, check with a pharmacist to see if it is safe to take along with your current prescribed medication. Paracetamol can be taken in normal doses while on anticoagulants. Changes in your medication should be written on the bottom slip of your dosage letter before your next blood test. |
| DON’T go on crash diets marked changes in the amount you eat can influence your INR. | Be moderate and consistent when planning your meals. There are certain foods that will have a greater impact than others on your INR result. |
| DON’T take more then moderate amounts of alcohol marked changes in consumption can be dangerous | |
| PREGNANCY. |
Oral anticoagulants taken in the early weeks of pregnancy carry a small risk of damaging the unborn child. If you are a woman of childbearing age receiving anticoagulants you should not start a pregnancy without consulting your doctor, who will be able to decide whether or not you should continue your anticoagulation therapy. If you find that your period is one week overdue, and you think you may e pregnant, you must see your doctor straight away. |
