Examining hepatitis C virus testing practices in primary care clinics

Area of Science:

• Hepatology
• Infectious Diseases
• Primary Care Medicine

Background:

• Hepatitis C virus (HCV) screening and testing in primary care settings have historically been suboptimal.
• Effective risk assessment and timely testing are crucial for managing HCV infection and preventing transmission.

Purpose of the Study:

• To evaluate the actual rate of HCV testing among primary care patients with identified risk factors.
• To identify specific variables that predict whether patients with HCV risk factors receive testing.

Main Methods:

• A prospective cohort study was conducted in four urban primary care clinics.
• Patients completed questionnaires to self-report HCV risk factors.
• HCV testing rates and predictive factors for testing were analyzed using adjusted odds ratios (aOR) and 95% confidence intervals (CI).

Main Results:

• Only 8% (46/578) of patients acknowledging HCV risk factors were tested within two months.
• Physician documentation of a specific HCV risk factor in the patient's chart was the only significant predictor of testing (aOR 4.5, 95% CI 2.1-9.5).
• Patients with documented risk factors had a testing rate of 16% compared to 5% without documentation.

Conclusions:

• A significant gap exists in HCV testing for at-risk individuals within primary care settings, with 92% remaining untested.
• Improving HCV testing rates requires enhanced physician awareness and documentation of patient risk factors.
• Targeted interventions focusing on clinical documentation are warranted to improve HCV screening in primary care.
