CONCORD, N.H. — The case of a medical technologist suspected of infecting patients with Hepatitis C could boost momentum for federal legislation requiring medical imaging and radiation therapy workers to meet standards before their employers receive Medicare reimbursements.

David Kwiatkowski is accused of stealing drugs and contaminating syringes used on patients at Exeter Hospital in New Hampshire, where 32 people have been diagnosed with the same strain of hepatitis C he carries. He previously worked at 18 hospitals in seven other states, moving from hospital to hospital despite having been fired twice over allegations of drug use and theft.

“Unbelievable,” said U.S. Rep. John Barrow, a Georgia Democrat and lead sponsor of the legislation. “That’s what happens when you have incredibly important, sophisticated work being done by folks who don’t have to be trained or certified or qualified to do it.”

Barrow’s comments came one day after a story by The Associated Press detailed how a lack of regulation, poor communication and Kwiatkowski’s own lies helped him slip through the cracks.

Kwiatkowski worked as a cardiovascular technologist, one of several specialized positions within a broader profession. According to the American Society of Radiologic Technologists, 45 states regulate at least one type of job involving medical imaging or radiation therapy. But education and certification standards vary widely. Alabama, Idaho, Missouri, North Carolina, South Carolina and Washington, D.C., have no regulations.

The organization has been advocating for years for a federal law that would direct the Department of Health and Human Services to create uniform standards that hospitals would have to meet if they receive Medicare payments. The latest version was introduced in June by Sens. Mike Enzi, R-Wyo., and Tom Harkin, D-Iowa. Barrow is one of 130 co-sponsors on the House side.

Though Congress failed to pass any of the previous versions, no significant opposition has emerged over the years, said Christine Lung, the society’s vice president of government relations. She hopes the Kwiatkowski case will add some traction.

“This is an issue that just hasn’t floated up into national prominence or attention,” she said. “I think it’s going to take situations like Mr. Kwiatkowski … to really make the public sit up and take notice.”

Members of New Hampshire’s congressional delegation were unanimous in calling the allegations about Kwiatkowski disturbing, but none have taken a position on the legislation.

Republican Sen. Kelly Ayotte said she would carefully consider any legislative remedies, but “the responsibility to help prevent such incidents ultimately rests with hospitals, which should conduct stringent background checks on potential employees and maintain strict oversight of narcotics and equipment.”

John Billings, chief of staff to Republican Rep. Charles Bass, offered a slightly different take.

“While medical licensing laws and regulations have traditionally been developed at the state level, Congress has an important oversight role in ensuring patient safety across the nation,” Billings said.

Kwiatkowski, who was arrested in July and charged with drug theft and tampering with a consumer product, told investigators he did not steal or use drugs. He has declined to comment, as have his court-appointed lawyers.
