Design and Proof of Concept of a Web-Based Questionnaire to Identify Patients at Risk for HIV and HCV Infection.

Despite remarkable improvement in the human immunodeficiency virus (HIV) and hepatitis C virus (HCV) care continuum, the rate of late diagnosis of HIV and HCV in high-income countries remains unacceptably high. Testing relies mainly on primary care physicians' identification of risk factors. We aimed to adapt an analogic to an online questionnaire to help HIV and HCV screening and perform a pilot study to assess its accuracy and acceptability.

Prevalence of HCV infection in a health area of Madrid (Spain): The first step towards microelimination.

Objective: To estimate the prevalence of HCV infection in the general population of a health area through an intervention in Primary Care, differentiating between new diagnoses and infections previously diagnosed but not treated.

Methods: Participants were selected through a risk assessment questionnaire, with all those who gave at least one affirmative answer and all those over 50 years of age undergoing a rapid test. Positive tests were confirmed in the lab by determination of anti-HCV antibodies by chemiluminescent microparticle immunoassay and determination of viraemia.

Outcome of an HIV education program for primary care providers: Screening and late diagnosis rates.

Background: Late HIV diagnosis remains one of the challenges in combating the epidemic. Primary care providers play an important role in screening for HIV infection. Our study aims to evaluate the relationship between knowledge and barriers to HIV testing and screening outcomes.
