Last month’s Pain Perspectives addressed the benefit of opioid agreements as an aspect of sound and prudent opioid prescribing. Many clinicians and academicians believe that stipulation for random urine drug testing (UDT) should be a part of any opioid agreement (1), with UDT serving the dual purposes of ensuring compliance with prescribed opioids as well as monitoring use of illicit drugs and non-prescribed medications (2).

In the modern era, UDT has its roots in the random testing of American soldiers to ensure abstinence from recreational drugs (3). The practice of drug screens in pain medicine was uncommon until the late 1990s, when a groundbreaking study by Fishbain and colleagues (4) determined that a significant proportion of patients with chronic pain were providing inaccurate information regarding their utilization of illicit drugs. Several years later Katz and Fanciullo performed a review on UDT (5), and concluded that it should be conducted routinely in patients with chronic pain being treated with opioids.

Despite being recommended in a number of pain management guidelines (6-8), research has indicated reluctance among many clinicians to conduct UDT. For example, in a 2001 study of primary care physicians treating chronic pain (9), only 8% were utilizing urine toxicology screens. In a 2006 study of primary care physicians (10), only 6.9% reported conducting UDT prior to prescribing and only 15% conducted testing on patients already prescribed opioids.

In a more recent article on the use of opioid risk reduction strategies in primary care (11), the authors determined that only 8% of patients receiving opioids received at least one UDT with only 24.4% of patients deemed to be at the highest risk receiving any urine toxicology screening. These figures are quite disturbing, particularly in light of the data that indicate that the prevalence of substance use disorders is 4 times higher among patients receiving opioid therapy than in the general population (12) and that as many as 44.6% of all patients with chronic pain prescribed opioids demonstrate at least some drug-related aberrant behavior (13).

It is important to consider what is not in the urine of patients prescribed opioids as well as what is in their urine. Much of the current opioid abuse crisis is due to diversion, and although “doctor shoppers” are often considered the primary perpetuators of diversion (14), data indicate that we cannot be too careful with any group of patients. Even populations that would not necessarily be thought to be at risk, such as seniors (15) and adolescents involved in organized sports (16), have been found to be at risk for diversion. When a urine drug test is negative for the prescribed opioid(s) in a patient who claims to be taking his/her opioids as prescribed, diversion certainly becomes a distinct possibility.

The bottom line is that urine drug testing is an important tool that should be used by all physicians whose pain management treatment regimens include chronic opioid therapy. For many years, UDT was extremely profitable for physicians, and was frequently abused as a means of increasing revenue (17). However, changes in the law (18) mandate that UDT is neither a profit generator nor a financial burden to the practitioner. Rather, it is a practice that will help save your patients’ lives, the lives of others in society, and protect your practice. In this era of DEA and state medical board scrutiny, the physician who exercises caution by requiring appropriate UDT is the legal, ethical, and effective pain manager.

I hope that you’ve found the information presented here thought-provoking. In next month’s column, I will address the important issue of how to effectively utilize UDT as an aspect of your pain management practice.
