The results of the program, spearheaded by the National Association of Children’s Hospitals and Related Institutions (NACHRI) and led by Marlene Miller, M.D., M.Sc., director of Pediatric Quality and Safety at Hopkins Children’s, are published online in the November issue of Pediatrics.
The research involved 29 pediatric intensive-care units (PICUs) and examined whether and how low-tech steps involving proper daily care and maintenance of central lines might reduce infection rates.
Researchers found that proper daily care of the central line slashed the number of infections by more than half (56 percent) over three years.
A central venous catheter, or central line, is a tube inserted into a major blood vessel in the neck, chest or groin to serve as portal for medication, fluids or blood draws in patients who need them frequently. Because central lines also provide quick direct access into a patient’s bloodstream in emergencies, children in the PICU often have them for weeks or months. Inserted incorrectly or mishandled after insertion, the central line can become a gateway for bacteria or other germs to enter the patient’s bloodstream, causing invasive disease and organ damage in these already vulnerable patients.
Because the catheter is often accessed multiple times a day after insertion, proper handling is critical, the investigators say. Basic precautions, such as daily assessment of the actual need for a central line and prompt removal if no longer needed; regularly changing the dressing covering the central line; changing the tubes and caps attached to it; cleaning the line before and after each use; and hand washing before handling the line can go a long way to keep bacteria and other bugs at bay.
The results, the investigators say, are impressive because they showed sustained and continuous reduction in infections over a long period of time and across PICUs with varying staffing, sizes and protocols.
“The drastic reduction in infections sustained over time and across many different hospitals shows that proper catheter care, when practiced rigorously and systematically, can be a game-changer in the battle against catheter-related infections,” says Miller, the study’s lead investigator and vice president for quality transformation at NACHRI.
Sustaining the success long term and curbing infection rates further will require the continuing education of medical staff, Miller says, adding that constant reminders to follow catheter protocol should be a mainstay in every PICU.
“The lessons learned can be applied beyond the PICU floor and, if made a national priority for all pediatric hospitals, these basic steps could lead to many more saved lives and reduce healthcare costs even further,” added Miller.
In an 18-month-long sub-study, researchers examined two more steps: additional scrubbing of the device’s cap with antiseptic solution before each access and placing antiseptic-soaked sponges at the catheter insertion site. Neither strategy reduced infection rates further, they found.
The findings are part of NACHRI’s ongoing quality improvement program, which started in 2006 and now includes 88 pediatric hospitals. In September, member hospitals announced that in five years the quality improvement program has saved 355 children’s lives and nearly $104 million by preventing nearly 3,000 central line infections. The program originated in pediatric intensive-care units, with hematology and oncology units — two other frequent users of central lines in children — joining a few years later.
Each year, 250,000 central line infections occur in the United States, researchers estimate, and up to one-fourth of patients die from them. Among children, up to one in five patients who get such infections die from them, researchers say. Each infection carries a price tag of up to $45,000.
Other Hopkins investigators in the study included Elizabeth Colantuoni, Ph.D., and Gayane Yenokyan, M.D., Ph.D.

Founded in 1912 as the children’s hospital of the Johns Hopkins Medical Institutions, the Johns Hopkins Children’s Center offers one of the most comprehensive pediatric medical programs in the country, with more than 92,000 patient visits and nearly 9,000 admissions each year. Hopkins Children’s is consistently ranked among the top children’s hospitals in the nation. Hopkins Children’s is Maryland’s largest children’s hospital and the only state-designated Trauma Service and Burn Unit for pediatric patients. It has recognized Centers of Excellence in dozens of pediatric subspecialties, including allergy, cardiology, cystic fibrosis, gastroenterology, nephrology, neurology, neurosurgery, oncology, pulmonary, and transplant. Hopkins Children’s will celebrate its 100th anniversary and move to a new home in 2012. For more information, please visit www.hopkinschildrens.org
