Trends in Hospitalizations of Patients with Hepatitis C Virus in Poland between 2012 and 2022

Abstract

Background: Analyzing hospitalizations of patients with hepatitis C virus (HCV) infection is essential for an effective action plan to eliminate hepatitis C as a public health threat. This study aimed to explore trends in hospitalizations of patients with HCV infection and factors related to these hospitalizations. Methods: This 11-year retrospective study (2012-2022) explored trends in hospitalizations of patients with HCV infection in Poland based on data from the Nationwide General Hospital Morbidity Study. Results: The mean age of individuals was 55 years, with hospitalization rates among men and women of 15.5 and 13.7 per 100,000 population, respectively. Hospitalizations were 1.8-fold higher among urban residents. The most frequent comorbidities were digestive (24%) and cardiovascular (18%) diseases. During the studied period, the hospitalization rates significantly decreased from 31.9 per 100,000 in 2012 to 5.0 per 100,000 in 2022, with stays requiring 0-3, 4-7, and ≥8 days becoming 8-fold, 6-fold, and 4-fold less frequent, respectively. The flattening of hospitalizations was apparent across all age groups, including children. Conclusions: While significant progress has been made in managing HCV in Poland, continued efforts are required to eliminate disparities in care and to sustain the momentum toward HCV elimination, particularly through enhanced political commitment and the implementation of comprehensive national screening programs.
