Hepatitis: risks for the surgeon
1Department of Surgery, University of New Mexico School of Medicine, Albuquerque 87106, USA.
Insights
Hepatitis B and C are significant occupational risks for surgeons due to blood-borne transmission. Vaccination prevents Hepatitis B, while barrier precautions are crucial for preventing Hepatitis C exposure.
Area of Science:
- Hepatology
- Infectious Diseases
- Surgical Safety
Background:
- Hepatitis B (HBV) and Hepatitis C (HCV) are major concerns for surgeons due to their blood-borne nature.
- Both viruses can lead to chronic liver disease, including cirrhosis, portal hypertension, and hepatocellular carcinoma.
- They pose occupational risks to surgeons through percutaneous injuries from infected blood.
Purpose of the Study:
- To highlight the risks of Hepatitis B and C infections for surgeons.
- To discuss the transmission rates, chronic disease potential, and prevention strategies for HBV and HCV in a surgical context.
- To emphasize the need for enhanced preventive measures against blood-borne hepatitis viruses in surgical settings.
Main Methods:
- Review of existing literature on Hepatitis B and C epidemiology and transmission.
- Analysis of transmission rates and chronic infection outcomes for HBV and HCV following occupational exposure.
- Evaluation of current prevention strategies, including vaccination and barrier precautions.
Main Results:
- Chronic Hepatitis B affects 1.25 million in the U.S. with a 25-30% transmission risk to healthcare workers via needle stick; 5% develop chronic disease. HBV infection is preventable with vaccination.
- Chronic Hepatitis C affects nearly 4 million in the U.S. with a lower needle stick transmission rate but a 50-80% rate of chronic disease. No vaccine exists for HCV.
- Hepatitis B is preventable by vaccine, while Hepatitis C prevention relies solely on avoiding blood exposure.
Conclusions:
- Hepatitis B and C represent significant occupational hazards for surgeons.
- Vaccination is effective for Hepatitis B prevention, but Hepatitis C requires strict adherence to blood exposure avoidance.
- Enhanced barrier use and surgical technique modifications are recommended to mitigate risks from known and unknown blood-borne hepatitis viruses.
Abstract:
Six different hepatitis viruses have now been characterized. Hepatitis B and C are the two hepatitis infections that are of greatest concern for surgeons. Hepatitis B and C share several features that have led to this concern. Both are blood-borne infections. Both are associated with chronic infection ultimately leading to cirrhosis, portal hypertension, and hepatocellular carcinoma, and both can be occupational infections for the surgeon after percutaneous injury associated with infected blood. Chronic hepatitis B infection is seen in 1.25 million people in the U.S. It is associated with a transmission rate to healthcare workers of 25 to 30 per cent following a hollow needle stick injury. Five per cent of acute infections result in chronic disease. It can be effectively prevented as an occupational infection by vaccination with the highly effective hepatitis B vaccine. Chronic hepatitis C infection is present in nearly 4 million people in the U.S. It has a lower rate of transmission than hepatitis B following needle stick injury, but it has a 50 to 80 per cent rate of chronic disease after acute infections. There is no vaccine for hepatitis C, and only prevention of blood exposure will avoid the risks of this occupational infection. Other hepatitis viruses are likely to be identified. Prevention of blood exposure, by the better use of barriers in the operating room and modification of surgical techniques, is recommended to prevent occupational infection from both known and unknown blood-borne viruses from the surgical patient.
