[The risk factors for hepatitis B virus infection in hospital personnel]
Insights
Hepatitis B infection risk factors in Peru include blood contact and needle washing. Removing these risks and optimizing staff rotation can reduce infection rates among healthcare workers.
Area of Science:
- Hepatology
- Infectious Diseases
- Public Health
Context:
- Viral hepatitis is a significant global health issue, particularly in Latin America.
- A case-control study was performed at Cayetano Heredia Hospital in Lima, Peru.
- The study aimed to identify risk factors for Hepatitis B virus (HBV) infection.
Purpose:
- To investigate the prevalence of Hepatitis B surface antigen (HBsAg) and antibodies (anti-HBs).
- To determine specific risk factors associated with Hepatitis B infection in the screened population.
- To identify high-risk groups within the hospital setting.
Summary:
- Screening of 492 individuals revealed a 0.41% HBsAg frequency and 8.13% anti-HBs frequency.
- Direct contact with blood and disposable needle washing were confirmed as significant risk factors for HBV infection.
- Sterilization room personnel and nurse-aids were identified as high-risk groups.
Impact:
- Implementing targeted interventions, such as improving needle washing practices and adjusting staff rotation, can reduce HBV incidence.
- The findings provide actionable insights for infection control strategies in healthcare settings in Peru and similar regions.
- Reducing occupational exposure can mitigate the public health burden of viral hepatitis.
Abstract:
Viral hepatitis is one of the leading causes of disease around the world. In Latin America is a severe public health problem. We conducted a case-control study in the Cayetano Heredia Hospital, Lima, Perú, seeking for risk factors for hepatitis B infection. We found 0.41% of frequency of HBsAg and 8.13% of anti-HBs in the 492 persons screened. Contact with blood was confirmed as a risk factor for hepatitis B infection; disposable needle-wash was also identified as a major risk factor. The personnel of the Sterilization Room is also in high risk for the infection. The nurse-aid personnel was also identified as a high-risk group. We suggest that the needle wash is a risk factor very easy to remove, and also stopping the rotation of the auxiliary personnel could reduce the incidence of the infection in the personnel at risk.
