Summary. The spread of hepatitis C virus (HCV) in Sweden in the 1970s indicated that serious liver complications (SLC) would increase in the 2000s. The aim of this study was to analyse the burden of HCV‐associated inpatient care in Sweden, to demonstrate the changes over time and to compare the findings with a noninfected population. The HCV‐cohort (n: 43 000) was identified from the national surveillance database 1990–2006, and then linked to national registers to produce an age‐, sex‐, and region‐matched noninfected comparison population (n: 215 000) and to obtain information on demographics, cancers, inpatient care and prescriptions. Cox regression was used to estimate the likelihood (hazard ratios) for admission to hospital in the HCV compared with the noninfected cohort. The hazard ratios were 4.03 (95% CI: 3.98–4.08) for all care, 77.52 (71.02–84.60) for liver‐related care and 40.74 (30.58–54.27) for liver cancer care. The admission rate in the HCV‐cohort compared with the noninfected cohort, the rate ratio (age‐ and sex‐adjusted) for all inpatient care was 5.91 (95% CI: 5.87–5.94), and the rate ratio for liver‐related care was 70.05 (66.06–74.28). In the HCV‐cohort, 45% of all episodes were for psychiatric, mostly drug‐related, care. Inpatient care for SLC increased in the 2000s. To conclude, drug‐related care was common in the HCV‐infected cohort, the demand for liver‐related care was very high, and SLC increased notably in the 2000s, indicating that the burden of inpatient care from serious liver disease in HCV‐infected individuals in Sweden is an increasing problem.
