Improve Compliance

Background: Even though serious efforts have been undertaken by different medical societies to reduce opioid use for treating chronic benign pain, many Americans continue to seek pain relief through opioid consumption. Assuring compliance of these patients may be a difficult aspect of proper management even with regular behavioral monitoring. Objective: The purpose of this study was to accurately assess the compliance of chronic opioidconsuming patients in an outpatient setting and evaluate if utilizing repeated urine drug testing (UDT) could improve compliance. Study Design: Retrospective analysis of prospectively collected data. Setting: Outpatient pain management clinic. Methods: After Institutional Review Board (IRB) approval, a retrospective analysis of data for 500 patients was conducted. We included patients who were aged 18 years and older who were treated with opioid analgesic medication for chronic pain. Patients were asked to provide supervised urine toxicology specimens during their regular clinic visits, and were asked to do so without prior notification. The specimens were sent to an external laboratory for quantitative testing using liquid chromatography-tandem mass spectrometry. Results: Three hundred and eighty-six (77.2%) patients were compliant with prescribed medications and did not use any illicit drugs or undeclared medications. Forty-one (8.2%) patients tested positive for opioid medication(s) that were not prescribed in our clinic; 8 (1.6%) of the patients were positive for medication that was not prescribed by any physician and was not present in the Illinois Prescription Monitoring Program; 5 (1%) patients tested negative for prescribed opioids; and 60 (12%) patients were positive for illicit drugs (8.6% marijuana, 3.2% cocaine, 0.2% heroin). Repeated UDTs following education and disclosure, showed 49 of the 77 patients (63.6%) had improved compliance. Limitations: This was a single-site study and we normalized concentrations of opioids in urine with creatinine levels while specific gravity normalization was not used. Conclusions: Our results showed that repeated UDT can improve compliance of patients on opioid medications and can improve overall pain management. We believe UDT testing should be used as an important adjunctive tool to help guide clinical decision-making regarding opioid therapy, potentially increasing future quality of care.

Background: Patients treated for chronic pain may frequently undergo urine drug testing to monitor medication compliance and detect undisclosed prescribed or illicit drug use. Due to the increasing use and abuse of benzodiazepines, this class of medications is often included in drug screening panels. However, immunoassay-based methods lack the requisite sensitivity for detecting benzodiazepine use in this population primarily due to their poor cross-reactivity with several major urinary benzodiazepine metabolites. A High Sensitivity Cloned Enzyme Donor Immunoassay (HS-CEDIA), in which betaglucuronidase is added to the reagent, has been shown to perform better than traditional assays, but its performance in patients treated for chronic pain is not well characterized. Objectives: To determine the diagnostic accuracy of HS-CEDIA, as compared to the Cloned Enzyme Donor Immunoassay (CEDIA) and Kinetic Interaction of Microparticles in Solution (KIMS) screening immunoassays and liquid chromatography-tandem mass spectrometry (LC-MS/MS), for monitoring benzodiazepine use in patients treated for chronic pain. Study Design: A study of the diagnostic accuracy of urine benzodiazepine immunoassays. Setting: The study was conducted at an academic tertiary care hospital with a clinical laboratory that performs urine drug testing for monitoring medication compliance in pain management. Methods: A total of 299 urine specimens from patients treated for chronic pain were screened for the presence of benzodiazepines using the HS-CEDIA, CEDIA, and KIMS assays. The sensitivity and specificity of the screening assays were determined using the LC-MS/MS results as the reference method. Results: Of the 299 urine specimens tested, 141 (47%) confirmed positive for one or more of the benzodiazepines/metabolites by LC-MS/MS. All 3 screens were 100% specific with no false-positive results. The CEDIA and KIMS sensitivities were 55% (78/141) and 47% (66/141), respectively. Despite the relatively higher sensitivity of the HS-CEDIA screening assay (78%; 110/141), primarily due to increased detection of lorazepam, it still missed 22% (31/141) of benzodiazepine-positive urines. The KIMS, CEDIA, and HS-CEDIA assays yielded accuracies of 75%, 79%, and 90%, respectively, in comparison with LC-MS/MS. Limitations: This study was limited by its single-site location and the modest size of the urine samples utilized. Conclusions: While the HS-CEDIA provides higher sensitivity than the KIMS and CEDIA assays, it still missed an unacceptably high percentage of benzodiazepine-positive samples from patients treated for chronic pain. LC-MS/MS quantification with enzymatic sample pretreatment offers superior sensitivity and specificity for monitoring benzodiazepines in patients treated for chronic pain.

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.

Objective: The Centers for Disease Control and Prevention (CDC) recommend that clinicians prescribing opioids for chronic pain should consider at least annual urine drug testing (UDT). We evaluated whether shorter intervals for repeat UDT are associated with decreased rates of drug misuse.Design: Retrospective analysis of deidentified serial UDT and matched prescribing data.Setting: We analyzed Quest Diagnostics 2016-2017 UDT results from new patients being monitored for prescription drug adherence, in nonsubstance use disorder (SUD) treatment environments.Main Outcome Measures: Drug misuse was defined as the absence of a prescribed substance or the presence of a nonprescribed substance. Patients with ≥3 sets of the UDT results were included.Results: UDT results from 49,601 patients (148,803 specimens) were tested. Declines in misuse between the first and second UDT were highest for those tested at the shortest intervals: approximately weekly, 19 percent; monthly, 15 percent; bimonthly, 12 percent; quarterly, 9 percent; semiannually, 3 percent; misuse rates increased by 1 percent for patients tested annually. Declines in misuse were more pronounced for opioids than other drug groups. Substantial declines in positivity were noted for heroin (32 percent) and nonprescribed fentanyl (10 percent). Declines in misuse between the second and third UDT followed a similar pattern.Conclusions: UDT intervals of ≤ quarterly were associated with marked declines, but testing annually or semiannually was not associated with consistent decreases. Our findings suggest that clinical strategies that include serial testing conducted quarterly or sooner may be instrumental in decreasing drug misuse. Testing more frequently than “at least once annually” should be considered by clinicians monitoring potential drug misuse.
