Risk of Bloodborne Infections for Nurses: What You Need to Know - Family Medicine

More Info

---

As a newly practicing nurse, it's understandable to be concerned about the risk of bloodborne infections, especially after an incident involving exposure to a patient's blood. The primary bloodborne pathogens of concern in healthcare settings include Hepatitis B (HBV), Hepatitis C (HCV), and Human Immunodeficiency Virus (HIV). Each of these viruses has different transmission routes and risks associated with exposure.


Understanding the Risks
1. Transmission Routes:
- HIV: This virus is primarily transmitted through direct contact with infected blood, sexual contact, or from mother to child during childbirth or breastfeeding. The risk of transmission through exposure to blood is significant, especially if the blood comes into contact with an open wound or mucous membranes.

- Hepatitis B and C: Both viruses are also transmitted through direct contact with infected blood. Hepatitis B is more infectious than HIV and can survive outside the body for up to a week. Hepatitis C, while less infectious than Hepatitis B, can still pose a risk if blood from an infected person enters your bloodstream.

2. Your Specific Situation:
- In your case, since you mentioned that blood from the patient splattered onto your fingers, and you have existing wounds (from frequent picking), there is a potential risk for infection. The risk increases if the blood was from a person who is known to be infected with HBV, HCV, or HIV.

3. Immediate Actions:
- Wash the Area: It is crucial to wash the exposed area thoroughly with soap and water as soon as possible. This can help reduce the risk of infection.

- Report the Incident: Notify your supervisor or the infection control department at your facility about the exposure. They will guide you on the next steps, which may include post-exposure prophylaxis (PEP) for HIV if the patient is known to be HIV positive.

- Testing: You may be advised to undergo baseline testing for HBV, HCV, and HIV. Follow-up testing may also be necessary after a few weeks to ensure that no infection has occurred.

4. Preventive Measures:
- Always use personal protective equipment (PPE), including gloves, when handling blood or bodily fluids. This is essential to minimize the risk of exposure.

- Be vigilant about hand hygiene and avoid touching your face, especially if you have open wounds or cuts on your hands.

- Familiarize yourself with your facility's protocols for handling blood and body fluid exposures.


Conclusion
While the risk of contracting HBV, HCV, or HIV from a single exposure incident can vary based on several factors (such as the viral load of the patient and the nature of the exposure), it is essential to take any exposure seriously. Prompt action, including washing the area, reporting the incident, and following up with appropriate testing, can significantly mitigate the risks involved.
As a healthcare professional, it's also important to stay informed about bloodborne pathogens and the best practices for preventing exposure. Regular training and adherence to safety protocols are vital in protecting both yourself and your patients. If you have further concerns or questions, don't hesitate to reach out to your facility's infection control team or a healthcare professional for guidance.
