What is a source patient testing?
Sometimes healthcare workers can be exposed to blood or other body fluids while caring for a patient, for example, by injury from a used needle or from a splash of blood or body fluids into their eye or mouth.
If this happens there is a risk of the healthcare worker catching any infections the patient may have. Sometimes the patient could have a serious infection which they or their doctors may not be aware of, for example, Hepatitis B, Hepatitis C or human immunodeficiency virus (HIV). In these circumstances the healthcare worker may need treatment and it is important that this is started quickly.
Why does this affect me?
A healthcare worker who has been looking after you has had an injury caused by a piece of equipment that has some of your blood or body fluid on it or was splashed by your blood.
You were probably not aware that this had happened and it was not your fault.
How can I help?
Because you were the patient being cared for when the injury happened, you are known as the source patient. We will ask if a sample of your blood can be taken for testing.
Would all patients be asked to have this test?
Whenever a patient is the known ‘source’ of such an injury, involving a healthcare worker, they will be asked to have this test. This standard procedure has been advised by the Department of Health.
What will the blood test involve?
A member of your medical team will ask for your written consent to take a sample of your blood. This will be tested in a laboratory to see if you have any blood-borne viruses, for example, either:
- Hepatitis B
- Hepatitis C
He or she will ask some questions about your health and lifestyle (like those asked at Blood Donation Centres). These give your doctor information about the chances that you may have one of these blood-borne viruses and help to decide if the healthcare worker needs immediate, urgent treatment.
Can I refuse to have the blood test?
You can choose not to give consent for the blood test. Refusing to have the blood test will not affect your treatment or future care in any way.
Will I get to know the results of the test?
Yes. One of your doctors will explain the result of your test.
What happens if my blood test is positive?
If your blood test is positive for one or more of the viruses you will be offered advice and given support. You will then be referred to a specialist doctor who will discuss the best treatment for you. The results of the test will be recorded in your healthcare record and also in the injured healthcare worker’s occupational health notes. Your GP will be told your results (unless you ask for this not to happen).
What happens if my blood test is negative?
If your blood test is negative the results of the test will be recorded in your own healthcare record and in the injured healthcare worker’s occupational health notes. Your GP will be told your results (unless you ask for this not to happen).
Will I have to tell insurance companies that I have had these tests?
No. Insurance companies should not ask if you have had an HIV or Hepatitis B or C test, had counselling in connection with such a test or received a negative test result. Doctors should not reveal this information when writing reports for insurance.
Ask one of your nurses or doctors if you want more information or if there is anything you are unsure about.
If you have any further questions or concerns, please ask your doctor or nurse, or you can contact a member of the hospital Infection Prevention and Control Team.
