ObjectivesIn parallel with the opioid epidemic, there has been a resurgence in abuse, medical complications, and deaths related to amphetamines. The opioid epidemic began with increasing rates of prescription products that evolved overtime to include heroin and more recently, fentanyl analogues. Current trends in amphetamine prescriptions are less well described. We sought to determine if there has been a change in amphetamine prescriptions given at discharge in U.S. emergency departments (EDs) in recent years.MethodsWe conducted a retrospective review of data provided by the National Hospital Ambulatory Medical Care Survey (NHAMCS) from 2012 to 2019. We computed total number of visits that were given amphetamine prescriptions (amphetamine salts, methylphenidate derivatives, and dexmethylphenidate) at discharge for each year. We computed the total number and rate of visits (of all ED visits) that had both amphetamines and opioids prescribed at discharge over the years. We computed data normality using Shapiro Wilke's test and used descriptive statistics such as mean to describe the data distribution as applicable. We used spearman's rho (SR) or pearson's correlation (PC) as applicable to describe trends in data. All p-values were one-tailed and were reported at a 0.05 significance level. All analyses were conducted in IBM SPSS version 28.Results/FindingsFrom 2012 to 2019, there were an estimated 817,895 ED visits where an amphetamine prescription was given at discharge, with an overall strong increase in rate over time (SR = 0.71, p = 0.02). At the beginning of the study period (2012) there were 83,503 (0.06%) visits and in 2019 there were 186,539 (0.12%) visits (123% absolute increase). On average, there were 102,237 (SD: 52,725) visits with discharge amphetamine prescriptions per year. There was a strong, linear increase in number of visits that involved a discharge amphetamine salt prescription (PC = 0.92, p = 0.001). In 2012, there were a total of 23,676 visits and in 2019, a total of 124,773 visits (427% increase). There was no trend in visits where both an amphetamine and opioid were prescribed (PC: 0.61, p = 0.06).ConclusionThere have been increases in discharge prescriptions for amphetamines in the ED over time. This was largely driven by prescriptions for amphetamine salts. Future research initiatives should continue to monitor this trend and in prescriptions and associated abuse in the setting of rising amphetamine abuse.Copyright © 2023 Elsevier Inc.
