ObjectivesOne of the most challenging areas of emergency medicine practice is the management and treatment of severe and persistent pain, including cancer-related pain. Emergency departments (EDs) in the United States frequently provide care for patients with cancer and an increasing concern is the potential for opioid misuse in this patient group. The authors determined the risk for opioid misuse among ED cancer patients with pain and assessed demographic and clinical factors associated with increased misuse risk. The Texas state prescription monitoring program was also queried for evidence of multiple opioid prescriptions for comparing low- and high-risk groups.MethodsThe Screener and Opioid Assessment for Patients with Pain-Revised (SOAPP-R) was administered to assess risk for opioid misuse among cancer patients presenting to the ED of a comprehensive cancer center in the United States. Eligibility criteria included: 1) presentation for treatment of chronic cancer-related pain while taking a prescribed schedule II opioid for analgesia, 2) age of 18 years or older, 3) ability to speak English, and 4) ability to understand the study and give written informed consent.ResultsOf 934 ED patients screened for the study, 290 were eligible and 209 participated (72% response rate). On the basis of the recommended SOAPP-R cutoff score of 18, a total of 71 of the 209 patients (34%) were categorized as having a high risk of misuse. Of note, 15% and 4% of all patients reported past or current use of illicit substances, respectively. The total number of annual opioid prescriptions (17.8 vs. 12.6; p = 0.023) differed between the high- versus low-risk groups. Multivariable analyses showed that depression (odds ratio [OR] = 3.06, 95% confidence interval [CI] = 1.45 to 6.48; p = 0.003), poor coping (OR = 1.08, 95% CI = 1.03 to 1.13; p = 0.001), and illicit substance use (OR = 28.30, 95% CI = 2.97 to 269.24; p = 0.029) were significantly associated with high risk of opioid misuse.ConclusionsThe risk of opioid misuse among cancer patients is substantial. Screening for opioid misuse in the ED is feasible.© 2016 by the Society for Academic Emergency Medicine.
