Recent trends in the prescription of opioids in the emergency department in patients with urolithiasis.

PURPOSE: Pain management is central in the treatment of urolithiasis. We aimed to estimate the impact of the 2017 Department of Health and Human Services declaration of an opioid crisis on prescribing patterns of opioids and NSAIDs in emergency department visits for urolithiasis. METHODS: The National Health Ambulatory Medical Care Survey (NHAMCS) was queried for emergency department visits of adults with a diagnosis of urolithiasis. The association between urolithiasis and narcotic and NSAIDs prescription patterns was evaluated and compared at pre-declaration (2014-2016) to post-declaration (2017-2018) periods. RESULTS: Opioids were prescribed in about 211 million (41.1%) out of 513 million emergency department visits, over a 5-year period. Diagnosis of urolithiasis accounted for 1.9% of the visits (6.0 million). The use of opioids was higher in urolithiasis (82.7%) compared to non-urolithiasis diagnosis (40.3%), as well as the use of multiple opioids per visit (p < 0.01 for all). There was an overall decrease in opioid prescriptions in the post-declaration period, - 4.3% for urolithiasis (p = 0.254) and - 5.6% for non-urolithiasis visits (p < 0.05). A decrease in the use of hydromorphone (- 47.5%. p < 0.001), an increase in the use of morphine (+ 59.7% p = 0.006), and an increase of 'other' opioids (+ 98.8%, p < 0.041), were observed. Opioids combined with NSAIDs comprised 72.6% of the opioid prescriptions and 62.3% of all analgesic prescriptions in visits with urolithiasis diagnosis. CONCLUSIONS: The use of opioids when managing urolithiasis decreased 4.3% after the crisis declaration; however, statistically are not different from pre-declaration numbers. Most often, opioids were prescribed with NSAIDs in urolithiasis patients.
