Colonoscopies Can Cause Greater Infection Risk
WEDNESDAY, June 6, 2018 (HealthDay News) — Getting a colonoscopy or an endoscopy may be riskier than you thought.
Researchers report that the rate of infections following these procedures at outpatient ambulatory surgery centers could be 100 times higher than previously believed, a new study finds.
Bacterial infections such as E. coli and Klebsiella can strike 1 in 1,000 patients after a screening colonoscopy, nearly 2 in 1,000 after a non-screening colonoscopy, and more than 3 in 1,000 after an endoscopy, the study authors said.
Using an insurance claim database, Hutfless and her colleagues gathered data from six states — California, Florida, Georgia, Nebraska, New York and Vermont. They tracked emergency room visits for infections and hospital admissions for seven and 30 days after a colonoscopy or endoscopy at an outpatient specialty center.
Hutfless’ team also found that people who had been hospitalized before one of the procedures had even a greater risk of infection.
In fact, nearly 45 in 1,000 patients hospitalized within 30 days before a screening colonoscopy went to the hospital within a month suffering from an infection. For those hospitalized before an endoscopy, the rate of infections was more than 59 per 1,000.
While the majority of these outpatient centers follow strict infection-control guidelines, the researchers found that rates of infections at some centers were more than 100 times higher than expected.
Endoscopy and colonoscopy have revolutionized treatment and prevention of gastric diseases, but patients should be aware of the risk of infection associated with these procedures, the researchers concluded.
The report was published June 1 in the journal Gut.
