RESUMO
The objective of this study was to analyse data related to hospitalization, comorbidities, average stays and costs associated with the hospitalization cases of hepatitis A in Spain, during the period between 2000 and 2005. A retrospective, descriptive study of the epidemiological characteristics of hepatitis A patients admitted to Spanish hospitals was performed using, as an information source, the Minimum Basic Data Set. National hospitalization rates were calculated for hepatitis A. Comorbidities, mortality, average and median stays, and mean medical costs related to hospitalization were analysed. Costs were calculated using Diagnosis-Related Groups for the disease. The total number of hospitalized patients with hepatitis A diagnosis was 2351 subjects (rate 1.87/100,000 inhabitants). The highest rate corresponds to the group aged between 20 and 39 years (3.07/100,000 inhabitants). Some 60.1% of hospitalized hepatitis A cases were diagnosed in men. Twenty-two deaths (0.9%) out of the total of hospitalized subjects were reported. The average hospital stay caused by hepatitis A was 6.8 days. The trends in the rate of hospitalized hepatitis A cases in Spain, from the year 2000 to 2005, were not statistically significant. Differences were found neither in the hospitalization percentage, nor in the average length of stay. An increase of cost from 836,278 euro in the year 2000 to 1,272,608 euro in the year 2005 was observed. The rate of hospitalized hepatitis A subjects in Spain has not changed over the period 2000-2005. The total cost derived from these hospitalizations has increased by 52%.
