Abstract

Objective: To evaluate which of the three studied strategies is the most effective to detect new cases of Hepatitis C virus (HCV) infections in primary care.

Methods: This is an observational, prospective, and multicentre study evaluating three strategies. Strategy 1: provide an explanatory letter to adults assigned to two primary care teams (PCTs), inviting them to have a blood test. Strategy 2: place posters and leaflets in PCTs advertising the possibility of laboratory tests. Strategy 3: reexamine HCV antibody test results in patients with hypertransaminasemia diagnosed within the last two years through electronic records, and determine anti-HCV status in undiagnosed cases.

Results: There were a total 598 participants (51% female with an average age of 50.6 ± 13 years). There were 238 people (4.1% of letters sent) in Strategy 1, 69 people (0.3% of potential participation) in Strategy 2, and 291 people (100% participation) from Strategy 3. One new case of HCV was found in both Strategy 1 and Strategy 2, representing a prevalence of 0.4 and 1.4%, respectively. Two new cases of HCV were found in Strategy 3, representing a prevalence of 0.7%.

Conclusions: The three studied strategies for detecting new cases of HCV infection are ineffective, especially in regards to their cost and effort.
