The increased risks of death and extra lengths of hospital and ICU stay from hospital-acquired bloodstream infections: A case-control study
Barnett, Adrian G., Page, Katie, Campbell, Megan, Martin, Elizabeth, Rashleigh-Rolls, Rebecca, Halton, Kate, Paterson, David L, Hall, Lisa, Jimmieson, Nerina L., White, Katherine M., & Graves, Nicholas (2013) The increased risks of death and extra lengths of hospital and ICU stay from hospital-acquired bloodstream infections: A case-control study. BMJ Open, 3, Article number-e003587.
- Hospital-acquired bloodstream infections are known to increase the risk of death and prolong hospital stay, but precise estimates of these two important outcomes from well-designed studies are rare, particularly for non-intensive care unit (ICU) patients. We aimed to calculate accurate estimates, which are vital for estimating the economic costs of hospital-acquired bloodstream infections.
- Case–control study.
- 9 Australian public hospitals.
- All the patients were admitted between 2005 and 2010.
Primary and secondary outcome measures
- Risk of death and extra length of hospital stay associated with nosocomial infection.
- The greatest increase in the risk of death was for a bloodstream infection with methicillin-resistant Staphylococcus aureus (HR=4.6, 95% CI 2.7 to 7.6). This infection also had the longest extra length of stay to discharge in a standard bed (12.8 days, 95% CI 6.2 to 26.1 days). All the eight bloodstream infections increased the length of stay in the ICU, with longer stays for the patients who eventually died (mean increase 0.7–6.0 days) compared with those who were discharged (mean increase: 0.4–3.1 days). The three most common organisms associated with Gram-negative infection were Escherichia coli, Pseudomonas aeruginosa and Klebsiella pneumonia.
- Bloodstream infections are associated with an increased risk of death and longer hospital stay. Avoiding infections could save lives and free up valuable bed days.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
