What Happened
A nurse working in a Massachusetts hospital emergency department tampered with carpujects — syringe devices used to administer injectable medication — containing hydromorphone and meperidine intended for patients in pain.
Over about two weeks in January 2016, the nurse used his credentials to enter false "cancel" or "return to stock" transactions in the emergency department's automated dispensing machine, which allowed him to remove carpujects without a legitimate administration record. He then used syringes to puncture the carpujects and withdraw portions of the hydromorphone and meperidine for his own use. In several instances he replaced the missing medication with saline and returned the diluted carpujects to the dispensing machine, where they remained available for other nurses to unknowingly administer to patients. A month before the tampering began, he had entered into an agreement not to practice nursing after being terminated from a previous job, but did not disclose that agreement to his new employer.
He pleaded guilty to tampering with a consumer product and to acquiring a controlled substance by deception and subterfuge. He was sentenced to one year and one day in prison, with the first year served in home confinement, plus three years of supervised release.
What Went Wrong
False transaction codes in the dispensing machine let a nurse pull medication out of the system without it ever appearing as administered to a patient. Key failures included:
- "Cancel" and "return to stock" transactions were not flagged for review even when used repeatedly by the same nurse in a short window.
- The nurse's prior agreement not to practice, reached with the state nursing board, was not disclosed to or discovered by his new employer before he was given access to controlled substances.
- Diluted carpujects were returned to the dispensing machine and administered to other patients without any tamper inspection catching the altered contents.
How It Could Have Been Prevented
- Flag and independently review "cancel" and "return to stock" transactions in automated dispensing machines, especially repeated use by the same staff member.
- Verify board-of-nursing status and any active practice agreements or restrictions as part of pre-employment and periodic re-credentialing checks.
- Inspect returned or reslotted syringes and carpujects for puncture marks or seal irregularities before they are made available for administration again.
- Reconcile dispensing-machine transaction logs against actual patient administration records on a routine basis in high-volume areas like the emergency department.
