Declines and regional variation in opioid distribution by US hospitals

The United States is enduring a preventable opioid crisis, particularly involving a population being treated in a hospital setting, a subset of whom may escalate to illicit opioids. This project analyzed trends in distribution of opioids by hospitals in the United States. Opioids monitored included buprenorphine, codeine, fentanyl, hydrocodone, hydromorphone, meperidine, methadone, morphine, oxycodone, oxymorphone, powdered opium, remifentanil, and tapentadol. The Automation of Reports and Consolidated Orders System (ARCOS) reports on substances controlled by the Drug Enforcement Administration. National data from ARCOS reports 5 and 7 from 2000 to 2019 were used for an observational study on hospital opioid distribution. Morphine milligram equivalents (MMEs) were calculated using oral conversion factors. The MME per person per state was calculated to compare data from the peak year, 2012, with data from 2019. Opioid use peaked in 2012, with a -46.6% decline from 2012 to 2019. Half (25) of the states have seen a decrease of -50% or greater. Of the opioid compounds observed, buprenorphine has seen increased (+122.5%) hospital use from 2012 to 2019. All other opioids have been experiencing a decline (>= 50%), particularly hydromorphone (-49.9%), oxymorphone (-57.7%), methadone (-58.7%), morphine (-66.9%), codeine (-67.5%), and meperidine (-77.6%). There was a 6-fold difference in population-corrected use of opioids in 2019 between the lowest (6.8 MME/person in New Jersey) and highest (Alaska = 39.6) states. This study demonstrates the considerable progress made thus far by hospitals in curbing the U.S. opioid crisis.

Automated summary

This study analyzed the trends in opioid distribution by hospitals in the United States and found a decrease in opioid use since 2012. While buprenorphine has increased in hospital use, other opioids have shown a decline. There was a significant difference in opioid use between states in 2019.
