The case of a surgical technician exposing 6,000 patients in Colorado to Hepatitis C while feeding her drug addiction has prompted legislators to consider requiring surgical staff to register with the state, the Associated Press reports.

The House Health and Human Services Committee heard testimony Thursday on two bills designed to increase oversight of the medical staffers. The bills’ sponsors say more oversight could have prevented Kristen Diane Parker from injecting herself with painkillers and leaving behind the dirty needles to be reused on patients.
