Bloodstream infection surveillance inconsistent between institutions, U-M study shows

Differences have significant implications in era of mandatory public reporting and pay-for-performance

2010-10-10
(Press-News.org) The study, led by Matthew Niedner, M.D., assistant professor of Pediatrics and Communicable Diseases at U-M C.S. Mott Children's Hospital, was conducted by the National Association of Children's Hospitals and Related Institutions Pediatric Intensive Care Unit Focus Group. It appears in the October issue of the American Journal of Infection Control.

"There is an intense amount of attention being placed on measures of quality performance that have significant implications in pay-for-performance, and reimbursement," says Niedner, who led the study. "What you have is a desire to measure quality but a lack of perfect measures. Measures are often 'good enough' to enable quality improvement, but can leave undesirable ambiguity when used comparatively as a metric of clinical performance."

Bloodstream infections are the most common hospital-associated infections in pediatric intensive care units (PICUs) and a significant source of in-hospital deaths, increased length of stay and added medical costs. Both adult and pediatric patients who have catheters inserted into their blood vessels face increased risk of developing an infection along the invasive plastic devices. The infections can become deadly as they spread into the bloodstream.

One hundred forty-six respondents from five professions in 16 PICUs completed surveys with a response rate of 40%. All 10 infection control departments reported inclusion or exclusion of central line types inconsistent with the Centers for Disease Control and Prevention CA-BSI definition, half calculated line-days inconsistently, and only half used a strict, written policy for classifying BSIs. Infection control departments report substantial variation in methods, timing, and resources used to screen and adjudicate BSI cases.

More than 80% of centers reported having a formal, written policy about obtaining blood cultures, but less than 80% of these address obtaining samples from patients with central venous lines, and any such policies are reportedly followed less than half of the time.

All of the surveyed infection control practitioners in the study said they used the Centers for Disease Control and Prevention's definition for CA-BSI, but none actually did, says Niedner. This has significant implications in the era of mandatory public reporting, pay-for-performance and Medicare's 'never events.'" The Centers for Medicare & Medicaid Services lists CA-BSI as a never event, and no longer reimburses for such hospital-acquired infections.

The study also showed that more aggressive surveillance efforts correlate with higher catheter-associated bloodstream infections rates. This suggests "that the harder one looks for CA-BSIs, the more likely they are to find them," Niedner says.

"From an internal perspective, you want an aggressive surveillance system that is inclusive of all possible cases, but from a public reporting or pay-for-performance standpoint, you'd like to exclude as many cases as you can," Niedner says. "There are no definitive national standards as to how to go about doing CA-BSI surveillance at the clinical practice level. It leaves wiggle room that pits hospital economics and reputation against quality improvement teams."

"If you are interested in improving quality of care, you look hard, if you're interested in reputation and reimbursement, maybe you don't look so hard," Niedner adds.

The study's findings offer a compelling opportunity for hospitals to improve their CA-BSI surveillance as a means to promote valid comparison among institutions, Niedner says. Current publicly reported data show that some hospitals report a four-fold difference in CA-BSI rates.

The current system makes it difficult to identify best performers, he adds. "You have to ask yourself, 'Is it because their care practices are good or is it because their surveillance is weak?"'

Niedner hopes this work spurs further research into improving hospital surveillance for such infections. Improved understanding of this variability and awareness of the potential consequences provides an opportunity and rationale to define CA-BSI surveillance best practices and work toward standardizing them across institutions, he adds.

"Many problems become more manageable when we standardize procedures," he says. "Various professional bodies have put forward recommendations for CA-BSI surveillance, but not at the level that will give it real traction. It's going to take a national entity endorsing standardized surveillance practices to improve the validity of institutional comparisons."

Targeted therapy promising for HER2-positive metastatic breast cancer

2010-10-10
A new type of breast cancer treatment has shown encouraging activity as a first-line therapy in HER2-positive metastatic disease, researchers reported at the 35th Congress of the European Society for Medical Oncology (ESMO) in Milan, Italy. Principal investigator Edith Perez, MD, Mayo Clinic in Florida, presented the results of the first ever randomized trial of trastuzumab-DM1 (T-DM1) as a first-line treatment for metastatic breast cancer. T-DM1 is the first of a new type of cancer medicine known as an antibody-drug conjugate. It binds together two existing cancer ...

Neurons cast votes to guide decision-making

2010-10-10
NASHVILLE, Tenn.—We know that casting a ballot in the voting booth involves politics, values and personalities. But before you ever push the button for your candidate, your brain has already carried out an election of its own to make that action possible. New research from Vanderbilt University reveals that our brain accumulates evidence when faced with a choice and triggers an action once that evidence reaches a tipping point. The research was published in the October issue of Psychological Review. "Psychological models of decision-making explain that humans gradually ...

Studying illnesses caused by worms: Scientists are learning how immune cells communicate

2010-10-10
Saranac Lake, N.Y. – A billion people living in underdeveloped areas around the world are infected with parasitic helminthes, worms that survive by residing in and feeding on their hosts. These infestations can cause chronic intestinal (and occasionally systemic) illnesses leading to long-term disability. Irah King and Markus Mohrs, biomedical researchers at the Trudeau Institute, are investigating illnesses caused by these gut-dwelling worms in an effort to decipher how immune cells send and receive signals that determine the specific immune response to mount. In a study ...

2010-10-10
TEMPE, Az. - An international team of scientists, exploiting pioneering techniques at Arizona State University, has taken a significant step toward unlocking the secrets of oxygenation of the Earth's oceans and atmosphere. Evolution of the Earth's multitude of organisms is intimately linked to the rise of oxygen in the oceans and atmosphere. The new research indicates that the appearance of large predatory fish as well as vascular plants approximately 400 million years ago coincided with an increase in oxygen, to levels comparable to those we experience today. If so, ...

Taking a fresh look

2010-10-10
Educational policy is controversial: positions on achievement gaps, troubled schools and class size are emotionally charged, and research studies often come to very different conclusions. But what if there was a new way of looking at the problem -- a way that treats education as a complex system (taking into account all interactions) and uses computer modeling and network analysis to provide a comprehensive look at the outcomes of policy choices? Researchers at Northwestern University's McCormick School of Engineering and Applied Science and School of Education and ...

Texas Tech researcher: Bee colony collapse associated with viral, fungal infection

2010-10-10
The sudden death of bee colonies since late 2006 across North America has stumped scientists. But today, researchers may have a greater understanding of the mysterious colony collapse disorder, said a Texas Tech University biologist. Shan Bilimoria, a professor and molecular virologist, said the bees may be taking a one-two punch from both an insect virus and a fungus, which may be causing bees to die off by the billions. Bilimoria is part of a team of researchers searching for the cause of the collapse. Led by research professor Jerry Bromenshenk from the University ...

2010-10-10
NASA's James Webb Space Telescope continues to make significant progress, successfully completing a series of sunshield vent tests that validate the telescope's sunshield design. "While adequate venting is a design consideration for all spaceflight hardware, this was a particularly unique challenge for the sunshield given the large volume of trapped air in the membrane system at launch," said Keith Parrish, Webb telescope sunshield manager at NASA's Goddard Space Flight Center in Greenbelt, Md. "From the beginning of its development venting features have been a critical ...

Women's race and class impact contraception recommendations, UCSF study shows

2010-10-10
A woman's race/ethnicity and socioeconomic status impact whether health care providers recommend one of the most highly effective forms of contraception, a UCSF study confirms. The results also indicate that the interaction of both factors plays a role in clinicians' decisions. Recommendations by health care providers previously have been found to vary by patients' race and socioeconomic status, contributing to health disparities, according to the researchers. The team investigated the effect of these factors on recommendations for contraception. Study results appear ...

Alienated youths are more likely to lash out

2010-10-10
When people are rejected by peers, they often lash out. In children, that aggression occasionally takes horrifying directions, leading to school shootings or other deadly acts. Researchers in the Netherlands found that some children are more likely than others to lash out in response to acute peer rejection: children who already feel like outcasts. "It was inspired by the fact that we had these school shootings and wondered what the most important feature of these kids could be," says Albert Reijntjes of Utrecht University, who cowrote the study with five other psychological ...
