Plain English Summary
Background and study aims
Hepatitis C is a virus that can infect the liver. Most people do not have any symptoms as they do not arise until the virus has caused significant damage to the liver. When they do occur, they tend to be vague and similar to a number of other conditions. They include flu-like symptoms, feeling tired and depression. People can get infected with the virus if they come into contact with the blood of an infected person, for example, by sharing drug needles. Due to the condition not having any obvious symptoms, regular testing is recommended for people considered to be in a high risk group, for example drug users. Here, we want to see if we can increase testing and diagnosis of people at an increased risk of hepatitis C virus (HCV) infection in the primary care setting (for example, at GP surgeries).
Who can participate?
Patients that have been approached by their GPs for HCV testing and attending a participating GP practice.
What does the study involve?
Participating GP practices are randomly allocated into one of two groups. Those in group one are given a complex intervention (or programme) consisting mainly of targeted case finding and inviting high risk patients to the practice for a test. Those in group two are not given the intervention and carry on as usual. We also look at how acceptable both patients and health care providers find the intervention and identify potential modifications that may be required to encourage HCV testing in primary care. At the end of the study we compare HCV testing, diagnosis, assessment and treatment rates between intervention and control sites. If the interventions are acceptable, work well and cost-effective then we will encourage their roll-out in primary care.
What are the possible benefits and risks of participating?
Some high risk HCV patients registered at the intervention practices may be given an earlier test or diagnosis as a result of the practice being involved in the study. For the participants involved in the qualitative study, although there may not be any direct benefit from taking part, they will be helping to improve future services and treatment accessibility for people living with HCV. We do not foresee any potential risks to the patients. For the qualitative interviews, the only risk we foresee is related to patient inconvenience related to consent procedures and participation in the interviews.
Where is the study run from?
Primary care practices in the South West of England (UK)
When is the study starting and how long is it expected to run for?
June 2015 to December 2016
Who is funding the study?
Department of Health - National Specialised Commissioning Team (UK)

Evaluation of interventions designed to increase diagnosis and treatment of patients with Hepatitis C virus infection in primary care
This study will determine whether we can increase testing and diagnosis of individuals at increased risk of HCV infection in primary care with a complex intervention consisting mainly of targeted case finding and inviting high risk patients to the practice for a test. We will also conduct a nested qualitative study with patients and health-care providers to assess the acceptability of the intervention and identify potential modifications that may be required to encourage HCV testing in primary care.
