ICU-related image

Healthcare associated infections (HAI) are a major source of morbidity and mortality despite the fact that they are often preventable. Most HAI are associated with an invasive device during a hospitalization and disproportionately occur in elderly intensive care unit (ICU) patients. The cost of HAI to hospitals is estimated to be 25.0 to 31.5 billion dollars annually. Because of the magnitude of HAI and drug resistance problem in hospitals, many states now mandate hospitals to publicly disclose data about their performance and/or infection rates. However, the effect of mandatory reporting of HAI is unknown.

In August 2007, Columbia University School of Nursing embarked on a three-year, two-phase study "Prevention of Nosocomial Infections and Cost Effectiveness Analysis" (P-NICE Study) to describe infection control department staffing and interventions implemented in ICUs across the nation. We surveyed a sample of National Healthcare Safety Network (NHSN) hospitals (n = 289, 66% response rate) and received data on 415 adult ICUs.

We found few hospital characteristics to be associated with device-associated HAI rates. We did find that the intensity of processes was varied; and only when an ICU had 95% greater compliance with processes (e.g., Central Line Bundle Elements) did rates decrease. However, with increased HAI caused by methicillin-resistant Staphylococcus aureus (MRSA) and Clostridium difficile, growing state mandatory reporting of HAI, and in the process of conducting the PNICE study, we have identified a number of gaps in the research that we will inform with the results of the P-NICER Study.
