The opioid epidemic continues to be a major public health crisis in the United States. According to the Center for Disease Control, approximately 8 million Americans reported misusing prescription opioids in 2023, with over 5 million Americans reporting that they suffer from opioid use disorder. The United States government estimates that 105,000 people died from drug overdose in 2023, and approximately 80,000 of those deaths can be attributed to opioids (\~76%). In acknowledgement of the opioid crisis, we wish to contribute to ongoing efforts to reduce unnecessary and excessive opioid prescription. In 2012, researchers in Iran published a randomized controlled trial comparing intravenous (IV) lidocaine to IV morphine for acute renal colic, reporting that 90% patients responded "successfully" in the lidocaine group versus 70% in the morphine group. They also concluded that there was a statistically significant difference between pain scores between the two groups at all time points, favoring the lidocaine group. However, the study was conducted at a single emergency department in Tabriz, Iran, with a relatively homogenous patient population, and the researchers did not explicitly define their primary outcome variable for what constituted a "successful" response in the treatment groups. The investigators of this study aim to build upon this preliminary evidence by recruiting a more diverse population to improve generalizability and by predefining pain-reduction thresholds to allow for more meaningful comparison between the interventions.
