Popis: | Background Implementing opt-out hepatitis C virus (HCV) screening across Canadian provincial prisons is crucial to achieving micro-elimination. Given short incarceration lengths, the most cost-effective screening strategy remains unknown. We compared the cost-effectiveness of current standard of care (venipuncture-based HCV-antibody+HCV RNA) and 13 alternative strategies in Quebec's largest provincial prison. Methods A prison cohort was simulated with a Markov micro-simulation model. Strategies differed in the biomarkers, sampling methods, and number of tests used. The model considered incarceration lengths, time to linkage to care (LTC), nursing costs, and tests’ costs, performances, acceptability and turnaround times. Outcomes included costs (Canadian dollars, CAD$), number of true positives linked to care, and incremental cost-effectiveness ratios (ICERs, additional $/additional TP-L). A one-year time horizon and health-payer perspective were adopted. Results Across all analyses, three strategies consistently provided the best value for money: venipuncture-based HCV-antibody+HCV-core antigen, venipuncture-based HCV-core antigen (base-case ICER=~ $720), and point-of-care HCV-antibody+HCV RNA (base-case ICER=$4,310). However, these strategies linked only 23%-29% viremic individuals to care. Main drivers of cost-effectiveness were the seroprevalence, proportion viremic, and time to LTC. Conclusion Alternative strategies would be more cost-effective than standard of care for implementing opt-out screening in provincial prisons. However, interventions to maximize LTC should be explored. |
