AbstractUrine drug screen (UDS) is a useful test conducted in patients receiving opioids for chronic pain to aid in validating patient adherence to opioid treatment and to detect any nonmedical opioid use (NMOU). One controversial topic regarding its use in palliative care is whether to conduct the test universally and randomly in all patients who are receiving opioids for chronic pain irrespective of their level of risk for NMOU, or to conduct the test selectively in only those with a high risk for engaging in NMOU behaviors. In this "Controversies in Palliative Care" article, 3 expert clinicians independently answer this question. Specifically, each expert provides a synopsis of the key studies that inform their thought processes, share practical advice on their clinical approach, and highlight the opportunities for future research. They all agreed that UDS has some utility in routine palliative care practice but acknowledged the insufficient existing evidence supporting its efficacy. They also underscored the need to improve clinician proficiency in UDS interpretation to enhance its utility. Two experts endorsed random UDS in all patients receiving opioids regardless of their risk profile while the other expert recommended targeted UDS until there is more clinical evidence to support universal, random testing. Use of more methodologically robust study designs in UDS research, examination of the cost-effectiveness of UDS tests, development of innovative programs to manage NMOU behaviors, and investigation of the impact of improved clinician proficiency in UDS interpretation on clinical outcomes, were important areas of future research that the experts identified.Copyright © 2023 American Academy of Hospice and Palliative Medicine.
