title: Hospitalization stay and costs attributable to Clostridium difficile infection: a critical review.
abstract: In most healthcare systems, third-party payers fund the costs for patients admitted to hospital for Clostridium difficile infection (CDI) whereas, for CDI cases arising as complications of hospitalization, not all related costs are refundable to the hospital. We therefore aimed to critically review and categorize hospital costs and length of hospital stay (LOS) attributable to Clostridium difficile infection and to investigate the economic burden associated with it. A comprehensive literature review selected papers describing the costs and LOS for hospitalized patients as outcomes of CDI, following the use of statistics to identify costs and LOS solely attributable to CDI. Twenty-four studies were selected. Estimated attributable costs, all ranges expressed in US dollars, were $6,774-$10,212 for CDI requiring admission, $2,992-$29,000 for hospital-acquired CDI, and $2,454-$12,850 where no categorization was made. The ranges for LOS values were 5-13.6, 2.7-21.3, and 2.8-17.9 days, respectively. The categorization of CDI attributable costs allows budget holders to anticipate the cost per CDI case, a perspective that should enrich the design of appropriate incentives for the various budget holders to invest in prevention so that CDI prevention is optimized globally.
