Hospital-Acquired Infections Cost Patients Time, Money, and Even Their Lives
Two studies examine what it costs patients when they get an infection while at the hospital

July 24, 2019 (Arlington, VA) — Below are summaries of studies published online today in Infection Control and Hospital Epidemiology. These articles will be freely available for a limited time. SHEA members have full access to all ICHE articles through the online portal.

Title: Attributable Costs and Length of Stay of Hospital-Acquired Clostridioides difficile: A population-based matched cohort study in Alberta, Canada
Summary: Clostridioides difficile CDI places a significant economic burden on the healthcare system. In this study, we used a population-54 based dataset of over two million patients and a rigorous propensity score based design and micro-costing data to determine the attributable cost and length of stay of HA-CDI among adult inpatients in Alberta, Canada. In this population-based, propensity score matched analysis using micro-costing data, we determined HA-CDI is associated with substantial attributable cost. (Ronksley/Leal)

Title: Impact of Multiple Concurrent Central Lines on Central Line-associated Bloodstream Infection Rates
Summary: The current methodology for calculating central line-associated bloodstream infection (CLABSI) rates, used for pay-for-performance measures, does not account for multiple concurrent central lines. This study compared CLABSI rates using standard National Healthcare Safety Network (NHSN) denominators to rates accounting for multiple concurrent central lines. Using the number of central lines as the denominator decreased CLABSI rates in ICUs by 25%. Patients with multiple concurrent central lines were more likely to be in an ICU, to have a longer admission, to have a dialysis catheter, and to have a CLABSI.


About ICHE
Published through a partnership between the Society for Healthcare Epidemiology of America and Cambridge University Press, Infection Control & Hospital Epidemiology provides original, peer reviewed scientific articles for anyone involved with an infection control or epidemiology program in a hospital or healthcare facility. ICHE is ranked 41st out of 89 Infectious Disease Journals in the latest Web of Knowledge Journal Citation Reports from Thomson Reuters.

The Society for Healthcare Epidemiology of America (SHEA) is a professional society representing more than 2,000 physicians and other healthcare professionals around the world who possess expertise and passion for healthcare epidemiology, infection prevention, and antimicrobial stewardship. The society’s work improves public health by establishing infection-prevention measures and supporting antibiotic stewardship among healthcare providers, hospitals, and health systems. This is accomplished by leading research studies, translating research into clinical practice, developing evidence-based policies, optimizing antibiotic stewardship, and advancing the field of healthcare epidemiology. SHEA and its members strive to improve patient outcomes and create a safer, healthier future for all. Visit SHEA online at, and @SHEA_Epi.
