What Happened
An ICU nurse at a Jacksonville hospital diverted fentanyl from syringes meant for critically ill patients and disguised the tampering by regluing the tamper-evident caps — until a hospital pharmacist noticed a damaged cap and traced a pattern in her dispensing records.
The nurse worked in the neurological intensive care unit of a Jacksonville hospital, providing care to patients with life-threatening neurological conditions who were prescribed intravenous fentanyl for pain control and anesthesia. To obtain drugs for personal use, she removed injectable fentanyl from syringes, replaced it with saline, and reglued the plastic tamper-evident caps back onto the syringes using adhesive she took from the hospital.
After her shift on September 28, 2021, a hospital pharmacist examining the ICU's fentanyl inventory found a syringe missing its tamper-proof cap, with foreign adhesive residue at the tip, and a second syringe with a cap that appeared reattached. Reviewing hospital records, a pharmacist supervisor found that she had checked out fentanyl doses and then cancelled the transactions, returning the syringes to inventory, 24 times between August 29 and September 28, 2021 — a pattern unique to her among nurses on the wing. When confronted the next day, she admitted tampering with fentanyl syringes since the summer of 2021; a search of her belongings turned up needles, saline syringes, and adhesive. She pleaded guilty to tampering with a consumer product, facing up to 10 years in federal prison.
What Went Wrong
- Checkout-then-cancel transactions weren't flagged in real time. Twenty-four cancelled fentanyl transactions from one nurse in a month were only caught retrospectively, after a physical defect was spotted.
- Tamper-evident packaging was defeated with ordinary adhesive. The caps' presence was checked visually rather than tested for integrity, allowing a reglued cap to pass as intact until closely examined.
- Diluted fentanyl reached critically ill patients. Patients dependent on IV anesthesia and pain control received a substance stripped of most of its potency without clinical staff or the patients being aware.
How It Could Have Been Prevented
- Generate automatic alerts for any single staff member's pattern of checking out and then cancelling controlled-substance transactions, rather than relying on a manual after-the-fact review.
- Physically inspect tamper-evident caps for reattachment or adhesive residue as part of routine inventory checks, not only when a defect is visually obvious.
- Restrict access to general-purpose adhesives and other cap/seal materials in areas where controlled substances are stored.
- Periodically test in-use vials and syringes of high-value diversion targets like fentanyl for actual concentration, especially in ICU settings where patients cannot report inadequate pain control.
