An unnerving case of a St. Paul nurse practitioner reusing syringes and exposing 161 patients to infection risk shows that unsafe injection practices still occur in U.S. health care. But the reasons remain a mystery.
In an era when contact lenses and mobile phones are disposable, researchers said they aren't sure why any health care providers deviate from long-standing practice and reuse syringes. But they do know the consequence: More than 150,000 people have been tested in the United States since 2001 for exposure to viruses such as HIV and hepatitis C due to unsafe injections by health care providers.
"I don't have a great answer for the why," said Dr. Melissa Schaefer, a leading researcher of unsafe injection practices for the U.S. Centers for Disease Control and Prevention. "But there are no acceptable reasons for the why."
Schaefer was surprised by her own national survey results last year, which showed that 12 percent of physicians believed that syringes had been reused in their facilities. Some providers might be trying to save money, she said, while others believe it is OK to use syringes if the needles are replaced, or if they don't pull back on the plungers to draw infectious material into the cylinder.
Trouble is, infections have spread despite these faulty assumptions, Schaefer said. "They do not protect against the contamination of the syringe or make it safe for reuse. The risk is still there."
Allina Health has tested 90 percent of patients who were exposed to infection risks at its St. Paul dermatology clinic by a nurse practitioner who started reusing syringes last October. So far, none appear to have infections that could have been transmitted via the syringes, an Allina spokesman said in a written statement.
While the risk is low, Allina officials will monitor these patients for months, because viruses such as hepatitis C can emerge slowly.
The nurse practitioner, who is no longer employed at the clinic, was first licensed as a registered nurse in 1978. She earned her NP license in 2014, according to records from the Minnesota Board of Nursing.
