Trends in opioid utilization in Hungary, 2006-2020: A nationwide retrospective study with multiple metrics.

This study was one of the recent opioid utilization studies using three volume-based metrics, covering a long time period. To our knowledge, this was also the first national, population level study describing opioid utilization in Hungary. National opioid utilization data suggested not an overuse but rather an underuse of opioid analgesics in a developed, Central European country.
