Study Shows Nationwide Declines in Central Line Infections and Ventilator-Associated Pneumonia

Hospitals across the country have seen sharp declines in rates of central line-associated blood stream infections (CLABSIs) and ventilator-associated pneumonias (VAPs) among critically ill neonates and children, according to a new study in the journal Pediatrics.

The study, "Healthcare-associated infections among critically ill children in the U.S.," analyzed incidences rates of CLABSIs, VAPs and catheter-associated urinary tract infections (CAUTIs) for 173 neonatal intensive care units (NICUs) and 64 pediatric intensive care units (PICUs) from 2007 to 2012.

"Central lines, ventilators and urinary catheters are commonly required as part of lifesaving medical care for critically ill neonates and children," said lead author Stephen Patrick MD, MPH, MS, assistant professor of pediatrics and health policy in the Division of Neonatology at Monroe Carell Jr. Children's Hospital at Vanderbilt. "When you use devices such as these in clinical care it makes children more vulnerable to infections. Over the last several years in neonatal and pediatric intensive care units around the country, we began to pay attention to the high rates of hospital-associated infections. Complications from these infections are serious, including death and long-term neurological injury and they are also costly to the healthcare system. For all of these reasons, hospitals began to develop protocols to reduce hospital-associated infections. For this study, we wanted to see how effective these efforts have been nationally in reducing these infections."

The study concluded that among the hospitals there was substantial decline in some infections during the investigation period. NICUs and PICUs both saw a 61 percent decline in central line-associated bloodstream infections. NICUs also saw a 50 percent reduction in ventilator-assisted pneumonias while PICUs rates dropped by 76 percent. Rates fell among neonates of all birth weights and among children.

Rates of catheter-associated urinary tract infections did not change significantly which could be attributed to variances in how CAUTIs are defined for surveillance purposes.

The study population included 174 hospitals reporting data to the Centers for Disease Control and Prevention for more than 5 million patient days, 1.2 million central line days and 380,000 ventilator days.

"For hospitals that participated in our study, we estimate that in addition to the harm that has been reduced there was approximately $131 million in savings of unnecessary healthcare expenditures," Patrick says.

Much of the changing tide over the years followed global calls for quality improvement efforts from concerned health organizations and systems. Nationally, a campaign called "Getting to zero" launched, while on the state level, the Tennessee Initiative for Perinatal Quality Care (TIPQC) was also implemented.

New policies and protocols were put into effect to reduce the unintended consequences of central lines and ventilators. Hospitals looked at various quality improvements including how and when lines were cleaned and used; if lines were necessary and for how long.

"This is a success story of multidisciplinary teams coming together to think, 'how do we make healthcare safer for America's children?' Our study shows these efforts appear to have been successful in reducing harm and saving millions of dollars for our healthcare system."

The study was supported by a grant from the Agency for Healthcare Research and Quality (R01HS018414-04).

This study was part of a collaborative effort between Vanderbilt University, Harvard Pilgrim Health Care, The Institute for Healthcare Improvement and the Centers for Medicare and Medicaid Services.
