Background: The precise role of urine drug testing (UDT) in the practice of pain
medicine is currently being defined. Confusion exists as to best practices, and even to
what constitutes standard of care. A member survey by our state pain society revealed
variability in practice and a lack of consensus.
Objective: The authors sought to further clarify the importance of routine UDT as an
important part of an overall treatment plan that includes chronic opioid prescribing.
Further, we wish to clarify best practices based on consensus and data where available.
Methods: A 20-item membership survey was sent to Texas Pain Society members.
A group of chronic pain experts from the Texas Pain Society undertook an effort to
review the best practices in the literature. The rationale for current UDT practices is
clarified, with risk management strategies outlined, and recommendations for UDT
outlined in detail. A detailed insight into the limitations of point-of-care (enzyme-linked
immunosorbent assay, test cups, test strips) versus the more sensitive and specific
laboratory methods is provided.
Limitations: Our membership survey was of a limited sample size in one geographic
area in the United States and may not represent national patterns. Finally, there is
limited data as to the efficacy of UDT practices in improving compliance and curtailing
overall medication misuse.
Conclusions: UDT must be done routinely as part of an overall best practice program
in order to prescribe chronic opioid therapy. This program may include risk stratification;
baseline and periodic UDT; behavioral monitoring; and prescription monitoring programs
as the best available tools to monitor chronic opioid compliance.
