Half Of Americans Tested Misuse Their Prescription Medications, According To Quest Diagnostics Analysis
Published: Sep 06, 2017
MADISON, N.J., Sept. 6, 2017 /PRNewswire/ -- A majority of test results of patients taking prescription medications show signs of drug misuse, including potentially dangerous drug combinations, finds a new large-scale analysis of laboratory test results from Quest Diagnostics (NYSE: DGX), the world's leading provider of diagnostic information services.
The Quest Diagnostics Health Trends study is based on analysis of the company's de-identified laboratory data, believed to be one of the largest nationally representative datasets of objective laboratory information of patients prescribed opioids and other commonly abused medications. Physicians order laboratory services to aid their ability to monitor patients for signs of prescription or illicit drug misuse or abuse.
The report, titled "Prescription Drug Misuse in America: Diagnostic Insights in the Growing Drug Epidemic," was released today at the medical conference PAINWeek 2017, being held September 5-9 in Las Vegas. The examination of 3.4 million prescription medication monitoring lab tests performed by Quest Diagnostics between 2011 and 2016 paints a stark picture of the continuing epidemic of prescription drug misuse, and the dangerous, potentially deadly patterns of that misuse.

The study found that while evidence of misuse has declined in recent years, 52 percent of test results showed evidence of potential misuse in 2016, suggesting a majority of patients took their prescribed drugs in ways that were inconsistent with their physician's instruction. By comparison, in 2011, 63 percent of test results were inconsistent with a physician's orders.
"Over the past several years, federal and state government, clinician organizations, public health advocates and providers have all launched campaigns to educate the public about the perils of prescription drug misuse, which hypothetically should have yielded a significant rate of improvement. Yet our study shows that every other American tested for possible inappropriate use of opioids and other prescription drugs is potentially at risk," said lead author F. Leland McClure, PhD, MSci, F-ABFT, director, medical science liaison, medical affairs, Quest Diagnostics. "This finding is rather shocking, and speaks to the challenges of combating the nation's drug misuse epidemic."
Potentially dangerous drug combinations observed in many patient test results
The study also found disturbing patterns of concurrent drug use.
Among more than 33,000 specimens tested for opioids, benzodiazepines, and alcohol in 2016, more than 20% were positive for both opioids and benzodiazepines, more than 10% were positive for both opioids and alcohol, and 3% were positive for all three.
Opioids and benzodiazepines depress the central nervous system. When combined, respiratory suppression, cardiac distress and even death by overdose can occur. While physicians may prescribe the two drugs together for some patients, the practice is generally regarded as risky; in August 2016 the United States Food and Drug Administration (FDA) issued a "boxed warning" on prescription opioids and benzodiazepines alerting prescribers to the dangers of concurrent use. According to the Centers for Disease Control and Prevention (CDC), more than 30 percent of opioid-related deaths also involved benzodiazepines.
The study also found that one in five (19%) specimens positive for heroin in 2016 was also positive for non-prescribed fentanyl. Fentanyl is 50-100 times more powerful than morphine. When combined with heroin, fentanyl heightens the risk of drug overdose death.
"Accidental drug overdose is a serious problem in the United States. It appears from our analysis that many patients may be at risk of overdose or other adverse health effects caused by concurrent use of opioids including fentanyl and other drugs such as benzodiazepines," said Jeffrey Gudin, MD, medical advisor, Quest Diagnostics, and Director, Pain Management and Palliative Care, Englewood Hospital and Medical Center, New Jersey. "Opioid prescribing guidelines issued by the CDC in 2016 advocate for drug testing patients prescribed opioids to monitor for potential misuse. These guidelines also recommended limiting benzodiazepines simultaneously to avoid dangerous drug interaction. Careful vigilance by prescribing physicians may help to offset some of the risks for patients who may be unaware of the dangers of combining these and other medications."
Misuse rates vary by age but drug use by adolescents is improving
Quest researchers found drug misuse rates were high among most age groups and both genders. However, adolescents (10 17 years of age) showed a striking improvement, with the inconsistency rate dropping from 70% to 29% between 2011 and 2016.
Misuse rates were even higher for men and women of reproductive age (58%) than in the general study population (52%). The findings are significant because opioid and benzodiazepine use may decrease male fertility and, if taken during pregnancy, increase the risk of birth defects and other health concerns.
