Quantifying the Adequacy of Opioid Analgesic Consumption Globally: An Updated Method and Early Findings.

Opioid analgesics are the mainstay for treatment of moderate and severe pain but, in many countries, the consumption of these medicines is inadequate. Over time, various groups have published opioid analgesic metrics, including authors from the World Health Organization. They linked consumption to a level considered adequate based on the actual consumption in developed countries. In this study, we present our current results on the adequacy of opioid analgesic consumption. We included statistics for 18 controlled opioid medicines that are primarily used as analgesics, and we developed the Adequacy of Opioid Consumption (AOC) Index. The average of the 20 most developed countries for 2015 is set as equal to an AOC Index of 100. An AOC Index of 100 or higher is considered adequate consumption. The average opioid analgesic consumption of the top-20 countries of the Human Development Index increased from 84 morphine milligram equivalents per capita (2000) to 256 morphine milligram equivalents per capita (2015). The extremes we found for 2015 were Germany (AOC Index: 304) and Nigeria (AOC Index: 0.0069). These extremes differ by 44 000 times. Adequacy of opioid analgesic consumption continues to be problematic around the world.
