Screening for hepatitis C virus in the Dartmoor prison population: an observational study

BACKGROUND: Prisons are a potential setting for hepatitis C screening. This study describes prisoner flows through such screening for all prisoners entering Dartmoor prison between 1 January 1998 and 30 June 2001. METHODS: We identified numbers at each step of the screening pathway, from screening to result, referral, biopsy and outcome. We describe the proportions of those screened who were seropositive; seropositives who were confirmed virus-positive; virus-positive cases attending for biopsy; and virus-positive cases eligible for treatment. RESULTS: Of 3034 entries into Dartmoor, 12 per cent were screened, with 16 per cent of these seropositive. Seventynine per cent of seropositive prisoners with a polymerase chain reaction result were confirmed virus-positive, and 27 per cent of these prisoners had a biopsy. Two prisoners were eligible for treatment. CONCLUSIONS: Screening uptake is low. Attrition rates are high, especially at the referral interface between the prison and specialist care. Finally, the yield of individuals eligible for treatment is low, at 7/1000 tested.
