The platform generates three Narx Scores based on a patient’s prescription activity involving narcotics, sedatives, and stimulants. A peer-reviewed study showed the “Narx Score metric could serve as a useful initial universal prescription opioid-risk screener.”
NarxCare’s algorithm-generated “Overdose Risk Score” draws on a patient’s medication information from PDMPs — such as the number of doctors writing prescriptions, the number of pharmacies used, and drug dosage — to help medical providers assess a patient’s risk of opioid overdose.
Bamboo Health did not share the specific formula behind the algorithm or address questions about the accuracy of its Overdose Risk Score but said it continues to review and validate the algorithm behind it, based on current overdose trends.
Guidance from the CDC advised clinicians to consult PDMP data before prescribing pain medications. But the agency warned that “special attention should be paid to ensure that PDMP information is not used in a way that is harmful to patients.”
This prescription-drug data has led patients to be dismissed from clinician practices, the CDC said, which could leave patients at risk of being untreated or undertreated for pain. The agency further warned that risk scores may be generated by “proprietary algorithms that are not publicly available” and could lead to biased results.
(Editor’s note: A citizen’s petition filed with FDA earlier this year alleged that NarxCare software “altered the practice of medicine in the U.S. to the detriment of patients,” and sought to have the software declared a misbranded medical device and recalled. The petition by the Center for U.S. Policy was rejected by FDA on technical grounds because it was “not within the scope” of the agency’s petition process.)
Impact on Patients
Bamboo Health says NarxCare’s rating system should never replace decisions made by physicians. But some patients say the risk scores have had an outsize impact on their treatment.
Bev Schechtman, 47, who lives in North Carolina, said she has occasionally used opioids to manage pain flare-ups from Crohn’s disease. As vice president of the Doctor Patient Forum, a chronic pain patient advocacy group, she said she has heard from others reporting medication access problems, many of which she worries are caused by red flags from databases.
“There’s a lot of patients cut off without medication,” according to Schechtman, who said some have turned to illicit sources when they can’t get their prescriptions. “Some patients say to us, ‘It’s either suicide or the streets.’”
The stakes are high for pain patients. Research shows rapid dose changes can increase the risk of withdrawal, depression, anxiety, and even suicide.
Some doctors who treat chronic pain patients say they, too, have been flagged by data systems and then lost their license to practice and were prosecuted.
Lesly Pompy, a pain medicine and addiction specialist in Monroe, Michigan, believes such systems were involved in a legal case against him.
His medical office was raided by a mix of local and federal law enforcement agencies in 2016 because of his patterns in prescribing pain medicine. A year after the raid, Pompy’s medical license was suspended. In 2018, he was indicted on charges of illegally distributing opioid pain medication and health care fraud.
“I knew I was taking care of patients in good faith,” he said. A federal jury in January acquitted him of all charges. He said he’s working to have his license restored.
One firm, Qlarant, a Maryland-based technology company, said it has developed algorithms “to identify questionable behavior patterns and interactions for controlled substances, and for opioids in particular,” involving medical providers.
The company, in an online brochure, said its “extensive government work” includes partnerships with state and federal enforcement entities such as the Department of Health and Human Services’ Office of Inspector General, the FBI, and the Drug Enforcement Administration.
In a promotional video, the company said its algorithms can “analyze a wide variety of data sources,” including court records, insurance claims, drug monitoring data, property records, and incarceration data to flag providers.
William Mapp, the company’s chief technology officer, stressed the final decision about what to do with that information is left up to people — not the algorithms.
Mapp said that “Qlarant’s algorithms are considered proprietary and our intellectual property” and that they have not been independently peer-reviewed.
“We do know that there’s going to be some percentage of error, and we try to let our customers know,” Mapp said. “It sucks when we get it wrong. But we’re constantly trying to get to that point where there are fewer things that are wrong.”
Prosecutions against doctors through the use of prescribing data have attracted the attention of the American Medical Association.
“These unknown and unreviewed algorithms have resulted in physicians having their prescribing privileges immediately suspended without due process or review by a state licensing board — often harming patients in pain because of delays and denials of care,” said Bobby Mukkamala, chair of the AMA’s Substance Use and Pain Care Task Force.
Even critics of drug-tracking systems and algorithms say there is a place for data and artificial intelligence systems in reducing the harms of the opioid crisis.
“It’s just a matter of making sure that the technology is working as intended,” said health economist Gibbons.
