Hazardous Drug Spills Put Cancer Nurses at Risk

While lifesaving to cancer patients, chemotherapy drugs can be hazardous for the health care workers who handle them, especially during a spill.

Inconsistent use of personal protective equipment when cleaning up a spill and problems with closed-system transfer devices — which are designed to prevent the release of toxic vapors and liquids — topped issues uncovered by a University of Michigan Rogel Cancer Center-led safety study involving nearly 400 nurses across 12 academic infusion centers.

The findings, which appear in the Clinical Journal of Oncology Nursing, highlight the need to improve reporting and training, and for additional research into the underlying causes of hazardous spills, the authors say.

“Our data show that there were more spills happening than might be expected and when they happen, nurses are often not following best practices to protect themselves from hazardous chemicals exposure,” says lead study author Christopher R. Friese, Ph.D., R.N., Elizabeth Tone Hosmer Professor of Nursing and a professor of Health Management and Policy at the University of Michigan. “There’s no national database for these type of spills, like there is for needle sticks, and our survey is a snapshot that points to a serious, widespread problem.”

Friese calls chemotherapy exposure an “invisible threat.” Health care workers can be exposed when they inhale chemical vapors or touch contaminated surfaces. Studies have found that nurses who reported handling hazardous drugs had twice the risk of reproductive problems. Other studies report incidences of rare cancers and various respiratory and skin conditions resulting from exposure.

The spill analysis was part of a continuing examination of data collected through a study called the Drug Exposure Feedback and Education for Nurses’ Safety, which launched in March 2015. Previously published work from the study explored efforts to increase the use of personal protective equipment.

In the new article, nurses at the 12 participating, high-volume ambulatory infusion centers reported 61 spills over the two-year study period. Only one facility reported zero spills, while one location reported 10.

Collectively, the reports revealed:

  • More than 65% of the spills occurred despite the use of a closed-system transfer device. And those devices reportedly didn’t function properly at least half of the time.
  • Recommended protective gear was only used a fraction of the time. Nurses donned two pairs of chemotherapy-rated gloves in 40% of the incidents. They wore a respirator, such as an N95 mask, in 30% of cases, and eye protection 20% of the time.
  • 11 of the incidents involved skin contact with a hazardous drug.

“I think there’s a sense in the health care community that these spills aren’t happening that often,” says Friese, who maintains a clinical practice in addition to his research program. “But these data show that this is a fairly common and serious threat to front-line cancer nurses.”

To understand how often these spills are happening and why, hospitals and clinics will need more robust data, Friese says.

“We need to make the reporting process easy, so that this can be a learning opportunity to improve practice,” he says. “It’s clear there are a multitude of factors involved in why these spills are happening and why nurses aren’t following guidelines meant to protect them during a clean-up.”

Additionally, with the current COVID-19 pandemic putting pressure on the availability of PPE, hospitals across the country are adapting their workflows to decrease the overall use of masks and gloves and gowns, Friese notes.

“But even during this challenging time, it’s important that nurses still wear the full complement of PPE when responding to a hazardous spill,” he adds. “Their future health may depend on it.”

Two years ago, U-M, through the support of the National Cancer Institute, developed a one day safety workshop for oncology nurses and pharmacists that includes training on handling hazardous drugs.

The study was supported by the National Institute for Occupational Safety and Health (R01OH010582), University of Michigan Center for Occupational Health and Safety Engineering (T42OH008455), the Rita and Alex Hillman Foundation, the Jonas Nurse Scholars Program and the American Cancer Society.

Additional authors on the paper include Mandy Wong of Northwestern University; Alex Fauer, Kari Mendelsohn-Victor and Marjorie C. McCullagh of the University of Michigan; and Martha Polovich of Georgia State University.
