Study Finds ‘Doctor Shopping’ Uncommon

Less than one percent of patients – about 135,000 people — who purchase prescription painkillers in the U.S. were classified as “doctor shoppers” in the first national study of opioid prescriptions and sales records.

But while they make up only a small proportion of the 48 million patients who are prescribed painkillers, researchers say patients who visit multiple doctors and pharmacies to obtain opioids are having an outsized impact on the system. Federal and state officials have cracked down on the illicit use of painkillers by making it harder for patients to obtain opioids – even ones with legitimate prescriptions.

“We estimate that a small outlying population of approximately one of every 143 patients who purchased opioids from retail pharmacies in 2008 obtained these prescriptions from a suspiciously large number of different prescribers. Patients in this population got an average of 32 prescriptions from an average of 10 different physicians,” wrote researchers Douglas McDonald and Kenneth Carlson of Abt Associates.

The study, published online in the journal PLOS ONE, analyzed records for over 146 million prescriptions dispensed in 2008 for opioids containing buprenorphine, codeine, fentanyl, hydrocodone, methadone, oxycodone, oxymorphone, propoxyphene, or tramadol.

The drugs were prescribed by over 900,000 doctors, dispensed by about 37,000 pharmacies, and given to over 48 million patients.

Patients classified as doctor shoppers purchased 4.3 million prescriptions, or nearly 2 percent of all opioid prescriptions sold in 2008. Some doctor shoppers saw over 200 different physicians that year, often crossing state lines to obtain prescriptions.

“The amounts of opioids purchased by patients in this extreme population are another strong signal of doctor shopping – an estimated average of 109 morphine equivalent milligrams per patient per day for the entire year. Even if these patients did not divert drugs for illicit purposes, obtaining opioids from such large numbers of prescribers may signal dangerously uncoordinated care,” the researchers said.

The risk of abuse was highest for oxycodone (2.8% of all prescriptions) and oxymorphone (2.3%). The lowest risk of abuse was for codeine (1.2%), fentanyl (1.2%), methadone (1%), and propoxyphene (1%).

To prevent abuse, most states have created prescription drug monitoring programs (PMPs) to collect sales records of painkillers. But studies have found that many physicians do not access PMPs before writing patients’ prescriptions. Many PMPs are not “user friendly” and often have rules that frustrate doctors. Physician awareness about the tools is poor, and some states restrict access, opening the database only to law enforcement officials.

“Ultimately, the front lines of defense against drug diversion by deceptive patients are manned by physicians and other healthcare providers who are authorized to prescribe scheduled drugs. Many of these providers are ill prepared,” the researchers said.

“Pain management has not been traditionally been a part of the curriculum in medical schools and surveys of physicians have found their knowledge of pain management principles to be deficient.”

The researchers said physicians could prevent doctor shopping by screening new patients for their risk of abuse and by monitoring their adherence to prescribed treatments. They also recommend that PMPs and health insurers scan prescription data to flag suspicious activity that may indicate doctor shopping, and then alert physicians and pharmacists about the patients.

The study found that most patients who were prescribed opioids did not abuse the drugs or used them sparingly.

Among patients using opioids during the first 2 months of 2008, 43% did not use the drugs for the rest of the year. Of those patients who continued to use opioids, 31% received their prescriptions from 1 physician and 14% from 2 physicians. About 3% of patients obtained prescriptions from 5 to 9 prescribers.

My doctor retired 4 yrs ago and I have not been able to find a doctor that would give me a prescription for pain meds.They will give me meds that I have had bad side effects from to the point I was admitted to the hospital several times.I’m going to do some more doctor shopping but If I can’t find a doctor then I’m going to look from the street.Chronic pain needs to be treated not ignored.


The Problem with my doctor and Physical medicine and rehab would not adjust my medical condition and pain for over 10 years,,So I was on gabapentin and norco 10/325 both now are causing tightening in my chest,, I plan on getting out of kaiser when the open enrollment for medicare to another pain managent

Unfortunately, those of us in the majority, who do not abuse our medications, or abuse the trust of our doctors, are paying the price for the tiny percentage that do.

It is unfortunate that because of the abuse by a few, the many have to suffer and not get adequate pain management. There is a big stigma against people that are chronic pain sufferers, that are on pain meds for extended use. What happened to being humane? My step-sister was dying of leukemia and was in horrible pain and the staff didn’t want to give her stronger meds for fear she would get addicted?! For God’s sake, she’s dying, she’s in bed crying and moaning in pain, just had a msmarrow transplant, make her comfortable and worry about addiction later. They did change needs finally. She died within the week.
