ContextThe annual consumption of opioid analgesics in the U.S. was more than 10 times the world average, whereas that in China was at a moderate level within Asia but much lower than the worldwide average. The opposite situations of opioid use in the U.S. and China revealed totally different problems in the developed versus developing world, that is, overuse versus underuse of opioids.ObjectivesThis study analyzed the clinical consumption, estimated the needs of pain treatment, and evaluated the adequacy of opioid analgesic consumption in mainland China and its seven regions.MethodsA retrospective analysis of the national and regional consumption of opioid analgesics in mainland China during 2006-2016 was conducted. The adequacy of consumption measure was used to gauge the overall adequacy of opioid analgesic consumption in morphine equivalents (MEs) for the treatment of moderate-to-severe pain in mainland China and compared with international data. Annual per capita consumption was adopted to measure the clinical consumption of opioid analgesics in MEs at a national level and across seven regions of mainland China. Needs of morphine for cancer pain treatment in mainland China and in its seven regions were estimated and compared with the clinical consumption of opioid analgesics in MEs.ResultsThe adequacy of consumption measure of mainland China ranged from 0.0041 to 0.0088 during 2006-2016, which was less than 1% of that in the reference countries. The poor North East region had only 10.85% of the cancer pain morphine needs fulfilled. The highest fulfillment rate was 36.02% in rich Southern China, which was 25.9% at the national level.ConclusionThe clinical consumption of opioid analgesics for the treatment of moderate-to-severe pain in mainland China was far below the international level. The annual per capita of clinical consumption was lower, and the adequacy of cancer pain treatment was poorer in less developed areas. All these findings call for actions to strengthen pain management.Copyright © 2019 American Academy of Hospice and Palliative Medicine. Published by Elsevier Inc. All rights reserved.
