Background The WHO has set a goal to decrease viral hepatitis-related fatalities by 65% by 2030. Aims To locate and retrieve to care all individuals diagnosed with hepatitis B, D or C, and investigate why they were not linked to appropriate medical management. Methods We conducted a retrospective-prospective search for patients with hepatitis B, D or C virus (HBV, HDV and HCV) infection in the central laboratory database of the Barcelona northern health area (catchment population, 450,000). We reviewed records and contacted candidates for retrieval who were offered a specialist medical visit. Results We reviewed records of 3731 patients with viral hepatitis (January 2019–December 2022): 1763 HBsAg+, 69 anti-HDV+ and 1899 HCV-RNA+. Among these, 644 (37%) HBV, 20 (29%) HDV and 1116 (56%) HCV patients were not currently linked to care. The proportion of patients receiving appropriate care was higher in HBV and HDV (p < 0.0001), and a higher percentage of unlinked hepatitis C patients had low life expectancy/comorbidities (39%; p < 0.0001). After implementing the linkage strategy, 254 HBV, 16 HDV and 54 HCV patients were successfully reintegrated into care. Among 1780 patients requiring linkage, 638 (35.8%) had moved to another health area or were missing essential contact data. Conclusions Among patients with viral hepatitis who required appropriate specialist care and were eligible for contact, 64% with HBV, 100% with HDV and 27% with HCV were successfully reintegrated into care. Overall, 324 (47.2%) eligible patients were linked to care, indicating the success of this strategy.
