Financial consequences of hospital-acquired bacteraemia in three Belgian hospitals in 2003 and 2004

SummaryThe financial and human costs of hospital-acquired infections are increasingly recognised in many healthcare systems. This study seeks to quantify excess expenditures on hospital-acquired bacteraemia (HAB) in three Belgian general hospitals in 2003 and 2004. Patients with HAB were compared with patients in the same All Patient Refined Diagnosis Related Groups (APR-DRGs) without HAB. Patient level costs were estimated using a hospital costing system developed by the ‘Université Libre de Bruxelles’, and compared with DRG-based funding for the three hospitals. HAB incidence was consistent with the national rate for two of the three hospitals, but considerably higher for the third. Both severity of illness and mortality were higher in the HAB group. Nosocomial bacteraemia was associated with an increased length of stay of 30 days and of 6.1 days in intensive care units. When compared with uninfected patients in the same DRG, treatment of HAB patients cost an additional €16,709. At current funding rates, hospitals made a mean profit of €446 for uninfected patients, but a mean loss of €2,431 for patients with HAB. Our findings suggest that hospitals have a financial interest in reducing the rate of HAB, even in a system which funds such complications through severity adjustments in the APR-DRG system. Growing international interest in pay for performance and other funding schemes will only strengthen these financial incentives.
