What Happened
Joseph V. Amello, a paramedic for a Massachusetts ambulance company, stole hundreds of vials of fentanyl from ambulance stock and, separately, tampered with vials intended for patients by replacing the drug with saline.
Between approximately November 2014 and August 2015, Amello stole more than 650 5-milliliter vials of fentanyl for his own use. Beginning around July 1, 2015, he escalated the scheme: he removed fentanyl from a number of vials that were intended for use on ambulance patients and replaced the drug with saline, then returned the tampered vials to circulation, putting patients at risk of receiving no pain relief during medical emergencies.
Amello pleaded guilty on June 22, 2017, to one count of acquiring a controlled substance by deception, fraud, and forgery, and one count of tampering with a consumer product. He was sentenced in November 2017 to 30 months in federal prison and three years of supervised release.
What Went Wrong
A paramedic diverted hundreds of fentanyl vials over roughly nine months, then began tampering with patient-bound vials, before the scheme was caught. Key failures included:
- Ambulance fentanyl stock was not reconciled frequently enough to catch the loss of more than 650 vials before the scheme escalated to direct patient risk.
- No tamper-evident vial controls existed to flag vials that had been opened, drained, and refilled with saline.
- Individual paramedic access to and usage of controlled substances was not tracked closely enough to surface an outlier pattern over many months.
- There was no routine potency testing of returned or in-service ambulance narcotic stock to catch dilution before it reached a patient.
How It Could Have Been Prevented
- Reconcile ambulance controlled-substance stock against usage logs on a per-shift basis to catch losses quickly rather than over many months.
- Use tamper-evident vial seals or single-use sealed kits for ambulance narcotics, inspected at shift changes.
- Randomly sample and lab-test in-service ambulance narcotic stock for potency to catch dilution before it reaches a patient.
- Track individual paramedic controlled-substance usage patterns over time to flag statistical outliers for review.
- Require two-person verification for restocking and reconciling ambulance drug boxes.
