What Happened
A Massachusetts nursing home nurse tampered with a dementia patient's morphine during an overnight shift, and the diluted dose was later administered to the patient before anyone caught it.
A registered nurse was employed by a Worcester County nursing home. From approximately 11:00 p.m. on November 6, 2020, until 7:00 a.m. the following morning, she was on duty in a unit specializing in care for residents suffering from dementia. During her shift, while entrusted with the care of a resident suffering from dementia, she tampered with a bottle of morphine sulfate prescribed to the patient, removing some of the morphine and adding water to the remaining supply. A nurse on a subsequent shift administered the adulterated, diluted morphine to the patient before the tampering was discovered.
She pleaded guilty on March 8, 2022, to one count of tampering with a consumer product and one count of obtaining a controlled substance by fraud and deception. She was sentenced on January 13, 2023, in federal court in Worcester to 52 months in prison and three years of supervised release. The Northborough Police Department assisted in the investigation, alongside the FDA's Office of Criminal Investigations and HHS-OIG.
What Went Wrong
A diluted morphine bottle was administered to a vulnerable dementia patient by another nurse before the tampering was caught. Key failures included:
- The morphine bottle's fill level and seal were not checked against dispensing records before the next shift's nurse administered a dose from it.
- A single nurse on an overnight dementia-unit shift had unsupervised access to a resident's controlled-substance supply with no witness present.
- Because the patient had dementia, self-reporting of reduced pain relief from a diluted dose was not a realistic detection mechanism, and no other safeguard filled that gap.
How It Could Have Been Prevented
- Require two-person verification for accessing and administering controlled substances to residents in dementia and other cognitively impaired care units, where patients cannot reliably self-report tampering.
- Check bottle fill levels and seal integrity against the last recorded administration before each new dose is drawn, especially at shift handoff.
- Use tamper-evident packaging for liquid opioid formulations dispensed to long-term care units.
- Monitor dementia and cognitively impaired residents' pain and symptom control more closely as a compensating control, given their inability to report diversion themselves.
