Is there a well-tested tool to detect drug-seeking behaviors in chronic pain patients?

Evidence summary

Drug-seeking behaviors—known as aberrant behaviors in chronic pain literature—may suggest a substance abuse disorder (TABLE).² At least 4 validated screening tools are available for predicting or monitoring aberrant behaviors in patients with chronic, nonmalignant pain disorders who are being considered for, or receiving, opioid therapy:

The Screener and Opioid Assessment for Patients with Pain (SOAPP-R) is a 24-item, self-administered questionnaire that stratifies patients being considered for opioid therapy into lower or higher risk for future opioid-related aberrant behaviors.² Each item queries frequency of behaviors and emotions consistent with opioid misuse and can be scored as 0 (never) to 4 (very often). The items on the SOAPP-R were developed by a consensus panel of pain and addiction experts.

In a multidisciplinary pain center study, the SOAPP-R was administered to 283 chronic pain patients who were followed for 5 months. At a cutoff score of ≥18, the test had a positive likelihood ratio (LR+) of 3.80 and a negative likelihood ratio (LR–) of 0.29 for detecting opioid misuse. At this cutoff, the SOAPP-R was 81% sensitive and 68% specific for predicting patients at high risk for aberrant behavior.

The Opioid Risk Tool (ORT) is a self-administered, 5-item questionnaire used to predict and monitor aberrant behavior.³ Potential scores range from 0 to 26. When administered to 185 consecutive new patients at a chronic pain clinic, a score of <4 had an LR– of 0.08 and a score of ≥8 had an LR+ of 14 for manifesting opioid-related aberrant behaviors. Some ORT scoring criteria have not shown consistent results in other studies.⁴

The Current Opioid Misuse Measure (COMM) is used to monitor aberrant behaviors in patients on opioid therapy.⁵ Scoring for the 17-item, self-administered test is similar to the SOAPP-R. In a study of 86 patients at a multidisciplinary pain center, a score of ≥9 detected opioid misuse with an LR– of 0.08 and an LR+ of 3.48, at a sensitivity of 77% and specificity of 66%.

The Addiction Behaviors Checklist (ABC) is a 20-item Yes or No questionnaire administered by staff.⁶ At a cutoff score of 3 positive items, it had a sensitivity of 88% and specificity of 86% for detecting opioid misuse in 136 consecutive patients at a multidisciplinary pain center.

Limitations of the studies

These studies have several limitations. The investigators who validated or evaluated the SOAPP-R and ORT included only patients at chronic pain clinics, so the instruments may not be applicable to patients in primary care settings^2-4; the ORT study lacked standard measures of addiction³; and the ABC was tested in a population that was predominantly male.⁶

Recommendations

A 2006 guideline of the American Society of Interventional Pain Physicians describes behaviors that suggest abuse or misuse of opioid medication.⁷ These behaviors, which are similar to those listed in the TABLE, include failure to experience pain relief from high-dose opioids, lying to obtain opioids, obtaining drugs from multiple prescribers, functional deterioration or lack of functional improvement, exaggerating pain, and forgery. The guideline recommends monitoring patients for such behaviors.
