Half of adolescents are misusing their prescription meds
MADISON, N.J. — Although prescription drug misuse is on the decline among adolescents, one in two patients tested between the ages of 10 and 17 years are not using their medications appropriately, according to an analysis by Quest Diagnostics. The analysis is based onon clinical lab testing performed by Quest Diagnostics laboratories as part of the company's prescription drug monitoring services.
“The Quest analysis shows that while our nation is making great strides to curb drug abuse and misuse, we have a long road ahead before we can declare victory on the prescription drug epidemic,” stated Leland McClure, director, medical science liaison, Quest Diagnostics. “By every means of slicing the Quest test data — age, gender, geography and payer type — we observed significant patterns of misuse in our nationally representative database. This is troubling because it strongly suggests, using objective lab data, that there truly is no good way to predict which patient may abuse a prescribed therapy — everyone is potentially at risk.”
Drug misuse is defined as evidence, based on lab test results, that a patient is using or combining non-prescribed drugs or skipping doses in a manner that is inconsistent with the ordering physician's directions. Quest's prescription drug monitoring test services help to identify evidence of use of up to 26 prescription and illicit drugs, such as opioids and marijuana.
However, patients in the 10-17 years age group also showed the greatest improvement in appropriate prescription drug use compared to all other age groups over a four-year period. In 2011, 70% of adolescents tested by Quest Diagnostics showed evidence of prescription drug misuse compared to 52% in 2014. These findings align with research from the National Institute of Drug Abuse, which revealed a decline in high school students' misuse of prescription drugs over the past two years.
The Quest Diagnostics Health Trends study, "Prescription Drug Misuse in America: Diagnostic Insights in the Continuing Drug Epidemic Battle," is based on an analysis of approximately 2.5 million de-identified test results on patients of all ages in 48 states and the District of Columbia. According to the analysis, the overall rate of prescription drug misuse for all ages was 53% in 2014, a decline of 16% relative to the rate of 63% in 2011.

Other key findings from the study:
All patients are at risk of prescription misuse. A high rate of prescription medication misuse (53%) was observed across all age groups and in both genders, as well as across patients enrolled in different types of health plans (Medicaid, Medicare and private payer);
The type of drugs misused varies by age. In adults 30 years of age and older, the two drug groups most likely to be misused, based on test results, were oxycodone and opiates. In children less than 10 years of age, amphetamines and opiates were most likely to be implicated in misuse. In patients 10-29 years of age, the leading drug groups associated with evidence of misuse were marijuana and opiates;
Some states and regions are curbing prescription drug misuse better than others. California, Florida, Georgia, Kentucky, New York, Pennsylvania and Tennessee all showed marked improvement in their inconsistency rates from 2011-2014. On a regional basis, the Mountain States and Great Plains states (Colorado, Montana, North Dakota, South Dakota, Utah and Wyoming) had the highest inconsistency rate, at 61%, while New York and New Jersey together had the lowest inconsistency rate, at 41%; and
Patterns of drug misuse shift over the past four years. The percentage of patients who did not take their medications consistently, suggesting they are skipping doses, increased from 40% in 2011 to 44% in 2014. Additionally, 35% of patients tested in 2014 showed evidence of combining drugs without a clinician's oversight, compared to 32% in 2011, indicating heightened potential for dangerous drug combinations.
