Urine Drug Test Interpretation: An Educational Program's Impact on Resident Knowledge and Comfort Level

INTRODUCTION: Following the release of the Centers for Disease Control and Prevention guidelines in 2016, institutions are encouraged to have controlled substance agreements that require the use of drug screens for appropriate opioid prescribing. Correct evaluation of urine drug tests (UDTs) is essential for appropriate chronic prescribing of controlled substances. Anticipating the increase in use of these tests, our institution developed and implemented an educational program to improve knowledge of and comfort level with UDT interpretation. METHODS: The educational program was 30 minutes in duration and consisted of a PowerPoint presentation followed by informal discussion. All internal medicine and medicine/pediatrics residents were encouraged to attend. A survey assessing knowledge of and comfort level with interpreting UDTs before, immediately after, and 2 months following the educational program was used as an assessment tool. RESULTS: A total of 44 out of 76 residents at our institution attended the educational program. The majority (81.8%) had no prior education on UDT interpretation; however, most (97.7%) stated they interpreted UDTs monthly, and 22.7% had refused refills within the prior month based on UDT results. Change in residents' knowledge and change in residents' comfort were both found to be significantly increased following the educational program (p < .0001 for both variables). DISCUSSION: Significant increases in both comfort with and knowledge of UDT interpretation occurred following the educational program provided for medical residents, which supports its expansion to other institutions as an easy and effective means of promoting appropriate UDT evaluation.
