An economic model to assess the cost and benefits of the routine use of silver alloy coated urinary catheters to reduce the risk of urinary tract infections in catheterized patients.
TL;DR: A model describes the extent of the burden of nosocomial urinary tract infections in terms of the number of patients affected and the costs incurred by the hospital sector; and identifies the potential benefits of the routine use of silver alloy coated catheters, as a means of reducing the incidence of this type of infection.
Journal Article
Economics and Preventing Hospital-Acquired Infection - Broadening the Perspective
TL;DR: In this article, the authors present a hypothetical model of the change in economic costs and health benefits to society that result from nosocomial infection-control programs, including costs incurred by the hospital sector, community health services and the private costs to patients.
The time-dependent bias and its effect on extra length of stay due to nosocomial infection
Adrian G. Barnett,Jan Beyersmann,Arthur Allignol,Victor D. Rosenthal,Nicholas Graves,Martin Wolkewitz +5 more
TL;DR: The time-dependent bias on the additive scale of extra length of stay of nosocomial infection is demonstrated, which shows examples where the time- dependent bias remains unchanged for the true discharge hazard ratios, but the bias for the extralength of stay is doubled because length ofStay depends on the infection hazard.
Journal ArticleDOI
