BackgroundGabapentinoids increasingly utilized for neuropathic pain, possibly to curb opioid prescribing. At the same time, data suggest subsequent increases in misuse and overdose of gabapentinoids, often in mixed overdoses. We sought to determine national trends and characteristics of gabapentinoid prescribing, including co-use with opioids, from the emergency department (ED).MethodsThis is a retrospective review of the National Hospital Ambulatory Medical Care Survey (NHAMCS) from 2012 to 2021. Our primary outcome was the trend in ED visits in which gabapentinoids were prescribed at discharge. Secondarily, we identified trends in gabapentinoid and opioid co-prescribing and gabapentin and pregabalin prescribing at ED discharge. We examined demographic data and used descriptive statistics, Shapiro Wilke's test, Pearson's Spearman's rho (SR) or Pearson's correlation coefficient (PC) as applicable. Neural networks were used to identify the most important predictors of opioid utilization during the same visit.ResultsBetween 2012 and 2021, there were an estimated 7,242,694 (0.53% of all ED visits) visits in which gabapentinoids were prescribed at ED discharge. Prescriptions increased from a total of 138,479 (0.1%) in 2012 to 893,495 (0.63%) in 2021 (PC: 0.85, p < 0.001). Opioids were co-prescribed in 27.2% of all visits in which gabapentinoids were prescribed, with no change over time (PC: -0.47, p = 0.09). Pregabalin prescription increased linearly over time (PC: 0.64, p = 0.02). The most important predictors of opioid administration or co-prescribing were whether an alternative provider (e.g., consult or nurse practitioner) saw the patient (100%), insurance (94.4%), age (75.9%), and region (75.2%).ConclusionDespite an association of misuse and overdose, often associated with opioids, gabapentinoids were increasingly prescribed at ED discharge. While these agents may be safer alternatives to opioids, misuse may be an associated consequence of increased prescribing, which warrants further investigation.Copyright © 2024 The Authors.
