Hospitalization and mortality due to hepatitis A in Taiwan: a 15-year nationwide cohort study

Summary Hepatitis A virus (HAV) is the most common food‐borne hepatitis in the world. The study objectives were (i) to describe the epidemiology of HAV‐related hospitalizations during 1997–2011 in Taiwan, (ii) to examine the age effect on the length of stay (LOS) in hospital and (iii) to study the f...

description Summary Hepatitis A virus (HAV) is the most common food‐borne hepatitis in the world. The study objectives were (i) to describe the epidemiology of HAV‐related hospitalizations during 1997–2011 in Taiwan, (ii) to examine the age effect on the length of stay (LOS) in hospital and (iii) to study the factors associated with death. The hospitalized cases were identified from the Taiwan National Health Insurance Research Database between 1997 and 2011 by ICD‐9‐CM code of 070.0/070.1. Patient sex, birthday, dates of hospitalization and death were analysed. A total of 3990 HAV‐hospitalized cases, males 2467 (62%), were identified. The LOS increased as patients’ age increased. The overall mortality rate was 16.8 per 1000 hospitalizations. Males had significantly higher case fatality rate than females (20.7 vs 10.5 per 1000 cases). The adjusted odds ratio (aOR) for death rose by age and increased rapidly over 40 years of age. The aOR and 95% confidence interval [95%CI] for aged 40–59 years and aged over 60 years were 7.89 (1.06–58.98) and 14.88 (2.02–109.40) compared to aged 0–19 years, respectively. Patients with chronic liver disease and cirrhosis had significantly higher risk of death (aOR=1.03 [1.01–1.04]), compared to those without liver disease. However, patients with liver disease, but no cirrhosis did not have higher risk of death (aOR=1.00 [0.99–1.01]). The aOR [95%CI] for LOS >9 day was 3.26 (1.96–5.40) compared to cases with LOS ≤9 days. Male sex, age over 40 years, cirrhotic liver and long LOS are significant factors associated with death in HAV‐hospitalized cases.
