Analysis of a hepatitis C screening programme for US veterans

Area of Science:

• Hepatology
• Infectious Diseases
• Public Health

Background:

• Hepatitis C virus (HCV) infection remains a significant public health concern, particularly among veteran populations.
• Existing screening guidelines (2001 National U.S. Veterans Health Administration) list 11 potential risk factors for HCV.
• Effective screening strategies are crucial for early detection and management of HCV.

Purpose of the Study:

• To analyze an HCV screening program among US veterans.
• To identify independent predictors of HCV infection based on established risk factors.
• To evaluate the effectiveness of current screening guidelines and propose targeted approaches.

Main Methods:

• Retrospective analysis of 5400 at-risk veterans undergoing screening between October 2001 and December 2003.
• Utilized questionnaires to identify at-risk individuals within primary-care settings.
• Employed multivariate logistic regression to determine independent predictors of HCV infection.

Main Results:

• Of 2282 veterans tested, 4.6% were confirmed HCV positive via PCR.
• Independent predictors of HCV infection included: injection drug use, blood transfusion before 1992, Vietnam era service, tattoos, and abnormal liver function tests.
• These five factors emerged as significant indicators in the multivariate model.

Conclusions:

• The study supports a more targeted screening approach for HCV in veterans.
• Focusing on five key risk factors can enhance the efficiency and effectiveness of HCV detection.
• This refined approach may optimize resource allocation and improve patient outcomes.
