Abstract

Objectives: Hepatitis C virus (HCV) poses a global public health threat. Prisons are a focus of prevention efforts due to high infection burdens. Expedition of treatment for incarcerated people is critical, as many are short- term sentenced. We evaluated point- of- care (PoC) HCV RNA testing in a maximum- security Scottish prison and assessed its impact on transition to treatment. We also evaluated costs and determinants of implementation.

Design: Mixed- methods evaluation of a single- centre care pathway pilot using National Health Service (NHS) data from 2018 to 2021. Descriptive statistics and survival analysis were undertaken. Cost analysis was assessed from a provider perspective. Healthcare staff participated in semistructured interviews and thematic analysis with a deductive approach was undertaken to identify implementation determinants.

Setting: A large maximum- security Scottish prison health centre administered by the NHS.

Participants: 296 incarcerated NHS patients (all men) and six NHS staff members (two men and four women).

Interventions: HCV testing using the Cepheid GeneXpert platform with Xpert HCV VL Fingerstick assay.

Outcome measures: The main outcome was survival (in days) from HCV test to treatment initiation. Secondary outcomes were cost- per- cure obtained and implementation determinants.

Results: During the pilot, 167 Xpert tests were administered, with an 84% completion rate, and treatment transition was superior for those who received it (p=0.014). Where PoC tests were administered, shorter survival to treatment was observed (19 vs 33 days: adjusted HR (aHR) 1.91 (1.03–3.55), p=0.040; 19 vs 50 days; aHR 3.76 (1.67–8.46), p=0.001). PoC was costlier than conventional testing. In qualitative analysis, most facilitators were observed among characteristics of individual domain while most barriers were noted in the inner setting.

Conclusions: Integrating PoC HCV RNA diagnosis into nurse- led HCV care in a maximum- security prison health centre shortens survival to HCV treatment. However, there are cost implications to this approach and multiple determinants that impact on implementation should be addressed.
