Economic impact of community- and nosocomially acquired rotavirus gastroenteritis in Austria

To determine the average costs per child for rotavirus (RV) acute gastroenteritis from different perspectives, from the hospital's, third-party payer's, pediatrician's and family's perspectives as well as in summary from the societal one.

This cost-of-illness study is based on data collected alongside a 6-month prospective, laboratory-confirmed epidemiologic study that evaluated the disease burden of RV infection in Austrian children < or =48 months of age. The study population at risk to contract a community- and nosocomially acquired acute gastroenteritis comprised 9,687 children. All of the 51 children with community-acquired and 33 with nosocomially acquired RV acute gastroenteritis were included in this analysis. The annual costs were estimated by means of extrapolation.

For community-acquired RV acute gastroenteritis, the average costs from the hospital's perspective were EURO (EUR) 97.8, from the third party payer's perspective 95.6 EUR, followed by 29.9 EUR and 9.8 EUR from the family's and pediatrician's perspectives, respectively. For nosocomially acquired RV acute gastroenteritis the average costs from the hospital's perspective were 1,494 EUR and from the third party payer's and family's perspectives 831 EUR and 116.8 EUR, respectively. In summary the average costs from the societal point of view for community-acquired RV acute gastroenteritis were 250 EUR and for nosocomial infections 2,442 EUR. After extrapolation the estimated total annual costs were 7.17 EUR million to 0.97 EUR million (13.6%) caused by community-acquired RV acute gastroenteritis and 6.2 EUR million (86.4%) caused by nosocomial RV acute gastroenteritis.

This cost-of-illness study clearly demonstrates the great impact of RV acute gastroenteritis, mainly of nosocomially acquired infection, on medical health care costs in Austria. To cut costs efforts in disease prevention should be encouraged.
