What Happened
A registered nurse at SSM Health St. Mary's Hospital in Janesville, Wisconsin was sentenced to 15 months in prison after pleading guilty to tampering with fentanyl vials and returning them to the hospital's automated medication dispensing system for use on other patients.
Dawn Drum withdrew fentanyl from vials, replaced it with saline, and resealed the vial stoppers with what appeared to be superglue before putting the tampered vials back into the automated dispensing/monitoring system so they would be available to other patients at the hospital. Hospital management identified the scheme in November 2021 after an audit of dispensing transactions in Drum's name revealed an excessive pattern of fentanyl overrides and wastes compared to other employees. When confronted with the discrepancy and asked to submit to a drug test, Drum refused and resigned from her position instead.
Drum pleaded guilty in May 2023 to one count of product tampering. She was sentenced in September 2023 to 15 months in prison, one year of supervised release, and a $30,000 fine. At sentencing, the court noted her conduct was driven by opioid addiction but that stealing fentanyl, tampering with the vials, and returning them for use on other patients caused real harm that warranted imprisonment.
What Went Wrong
A nurse was able to divert fentanyl, disguise the tampering with a resealed stopper, and return the vials to circulation for use on other patients until a dispensing-pattern audit caught her months later. Key failures included:
- Tampered vials with resealed stoppers were not caught by visual inspection before being placed back into the dispensing cabinet.
- Fentanyl override and waste patterns were only reviewed periodically rather than through continuous, automated anomaly monitoring, letting an excessive pattern persist through most of 2021 before an audit flagged it.
- No routine potency or seal-integrity testing existed to catch a diluted vial before it reached another patient.
How It Could Have Been Prevented
- Run continuous, automated analysis of override, waste, and withdrawal patterns from the dispensing/monitoring system rather than relying on periodic manual audits.
- Inspect returned vials for tampering — resealed stoppers, altered fill level, or discoloration — before they re-enter the dispensing cabinet.
- Require witnessed waste, documented immediately, for any controlled substance not fully administered.
- Escalate an employee's refusal of a for-cause drug test to an immediate suspension of dispensing access pending investigation.
