Study finds 71 percent of medical scopes tainted by bacteria new hampshire youtube electricity

The paper, published last month in the American Journal of Infection Control, underscores the infection risk posed by a wide range of endoscopes commonly used to peer deep into the body. It signals a lack of progress by manufacturers, hospitals and regulators in reducing contamination despite numerous reports of superbug outbreaks and patient deaths, experts say.

“These results are pretty scary,” said Janet Haas, president of the Association for Professionals in Infection Control and Epidemiology. “These are very complicated pieces of equipment, and even when hospitals do everything right we still have a risk associated with these devices. None of us have the answer right now.”

Researchers said the findings confirm earlier work showing that these issues aren’t simply confined to duodenoscopes, gastrointestinal devices tied to at least 35 deaths in the U.S. since 2013, including three at UCLA’s Ronald Reagan Medical Center. Scope-related infections also were reported in 2015 at Cedars-Sinai Medical Center in Los Angeles and Pasadena’s Huntington Hospital.

The study’s authors said the intricate design of many endoscopes continues to hinder effective cleaning and those problems are compounded when health care workers skip steps or ignore basic protocols in a rush to get scopes ready for the next patient. The study identified issues with colonoscopes, bronchoscopes, ureteroscopes and gastroscopes, among others.

“Sadly, in the 10 years since we’ve been looking into the quality of endoscope reprocessing, we haven’t seen improvement in the field,” said Cori Ofstead, the study’s lead author and an epidemiologist in St. Paul, Minn., referring to how the devices are prepared for reuse.

The rise of antibiotic-resistant superbugs such as CRE (carbapenem-resistant Enterobacteriaceae), which can be fatal in up to half of patients, has made addressing these problems more urgent. About 2 million Americans are sickened by drug-resistant bacteria each year and 23,000 die, according to the federal Centers for Disease Control and Prevention.

“We’re not moving fast enough to a safer world of reusable medical devices,” Michael Drues, an industry consultant in Grafton, Mass., who advises device companies and regulators. “There is plenty of fault to go around on device companies, hospitals, clinicians, on basically everybody.”

Last month, the FDA issued warning letters to Olympus and two other scope makers for failing to conduct real-world studies on whether health care facilities can effectively clean and disinfect their duodenoscopes. The FDA ordered the manufacturers to conduct those reviews in 2015 after several scope-related outbreaks in Los Angeles, Seattle and Chicago made national headlines.

Among the safety issues: Hospital technicians wore the same gloves for handling soiled scopes fresh after a procedure and later, when they were disinfected and employees wiped down scopes with reused towels. Storage cabinets for scopes were visibly dirty and dripping wet scopes were hung up to dry, which is a known risk because bacteria thrive on the moisture left inside.

Ofstead and her co-authors recommended moving faster toward sterilization of all medical scopes using gas or chemicals. That would be a step above the current requirements for high-level disinfection, which involves manual scrubbing and automated washing.
