Are Rx Drug Databases ‘Trojan Horses’ for Law Enforcement?

By Pat Anson, PNN Editor

Prescription drug monitoring programs (PDMPs) were widely adopted in the U.S. over a decade ago to help identify patients who might be abusing opioid medication or other controlled substances. All 50 states now have databases that physicians and pharmacists can use to monitor a patient’s prescription drug history and look for possible signs of abuse.

Although widely billed as a way to improve patient safety and prevent diversion, critics say PDMP’s quickly became a surveillance tool for local and federal law enforcement --- in effect, ‘Trojan Horse’ technologies that turned pharmacists into undercover cops.

“Equipped with PDMPs, pharmacists readily police patients. Pharmacists use this surveillance tool to interrogate patients about their drug use, document interactions defensively, and let patients know they are being watched,” said Elizabeth Chiarello, PhD, an Associate Professor of Sociology at Saint Louis University.

“PDMPs are surveillance technologies, not healthcare tools, so they do not offer pharmacists new ways to deal with patients’ pain or substance use disorders, they simply empower pharmacists to view patients with suspicion and refuse to treat them.”

Chiarello conducted 118 interviews with pharmacists in six states, asking how PDMP’s have affected their work and relationships with patients. Her findings, recently published in American Sociological Review, suggest that many pharmacists now feel pressured to work with law enforcement to identify suspicious prescriptions.   

A pharmacist in Mississippi said she was approached by a DEA agent, who gave her his card and said, “Call me anytime you need me.”

“From then on, she called the DEA when she spotted a fake prescription and worked with them to arrest the patient,” wrote Chiarello. “Pharmacists have become more comfortable deciding which patients deserve opioids and turning away those deemed undeserving. PDMP use has also strengthened communication with law enforcement, so pharmacists now contact them about troubling patients.”

A pharmacist in Missouri told Chiarello that he and his colleagues “work pretty well” with local law enforcement:

“We get calls all the time from the police that say ‘Hey, can you find out if they’re actually on this?’… I’ll call the police if I ever need any help, especially with someone who is jumping from pharmacy to pharmacy or doing something that’s illegal. But they’ll come back to me as well saying, ‘Hey, can you check the fill dates for this guy or can you check where he’s been filling for me?’ And so they kind of use me as a PDMP resource as well.”

Congressional investigators recently reported that three pharmacy chains -- CVS, Kroger and Rite Aid – faced “extreme pressure” from law enforcement to immediately respond to requests for patient information, even without a warrant. In most cases, patients are not informed that their medical records have been shared with law enforcement or why they were being sought.

Only three states – Louisiana, Montana and Pennsylvania – have laws that require a warrant or subpoena before medical data is disclosed.  

‘We Don’t Go Fishing’

In a recent webinar with medical providers, a DEA investigator denied that the agency uses PDMPs to troll for suspicious patients and providers.

“This comes up sometimes, so I'll just address the elephant in the room. We don't go fishing in the (PDMP) data. Okay? Why do people think we have this open access to driving records and that we pull whatever we want? No. We have to have a case and we have to have a subpoena. We just don't go trolling through the records,” said Jed Nitzberg, a DEA Supervisory Diversion Investigator.

The DEA has long been interested in prescription drug records. In 2020, the agency solicited bids from contractors to create and operate a surveillance program that would identify patients, prescribers and pharmacies that may be involved in the diversion or abuse of drugs.

Under the proposed program, the DEA would have “unlimited access” to prescription data, including the names of prescribers and pharmacists. The names of patients would be redacted, but if investigators suspect a drug was being abused or diverted, they could get a subpoena to identify them. No contract was awarded by DEA and it’s unclear if the surveillance program was ever initiated.

Even without prompting from law enforcement, pharmacists are under enormous pressure to be alert to suspicious behavior by patients and physicians. Under the national opioid settlement, if a pharmacy has too much “Red Flag activity” such as patients paying for drugs in cash or a prescription written by a doctor in another zip code, it risks being terminated from receiving any more shipments of opioids and other controlled substances.

Ironically, the theft, loss and diversion of prescription opioids is at its lowest level in over a decade. In the DEA’s latest National Drug Threat Assessment, the agency said the number of “unaccounted-for” opioids had fallen by 80 percent, from 19.5 million pills/units in 2011 to just 4 million in 2023.
