Death by prescription painkiller

The number of deaths involving commonly prescribed painkillers is higher than the number of deaths by overdose from heroin and cocaine combined, according to researchers at McGill. In a first-of-its-kind review of existing research, the McGill team has put the spotlight on a major public health problem: the dramatic increase in deaths due to prescribed painkillers, which were involved in more than 16,000 deaths in 2010 in the U.S. alone.

pillsFirst major review provides evidence of sharp increase in deaths from painkillers in U.S. and Canada

The number of deaths involving commonly prescribed painkillers is higher than the number of deaths by overdose from heroin and cocaine combined, according to McGill researchers. In a first-of-its-kind review of existing research, the McGill team has put the spotlight on a major public health problem: the dramatic increase in deaths due to prescribed painkillers, which were involved in more than 16,000 deaths in 2010 in the U.S. alone. Currently, the U.S and Canada rank #1 and #2 in per capita opioid consumption.

“Prescription painkiller overdoses have received a lot of attention in editorials and the popular press, but we wanted to find out what solid evidence is out there,” says Nicholas King, of the Biomedical Ethics Unit in the Faculty of Medicine. In an effort to identify and summarize available evidence, King and his team conducted a systematic review of existing literature, comprehensively surveying the scientific literature and including only reports with quantitative evidence.

“We also wanted to find out why thousands of people in the U.S and Canada are dying from prescription painkillers every year, and why these rates have climbed steadily during the past two decades,” says King, “We found evidence for at least 17 different determinants of increasing opioid-related mortality, mainly, dramatically increased prescription and sales of opioids; increased use of strong, long-acting opioids like Oxycontin and methadone; combined use of opioids and other (licit and illicit) drugs and alcohol; and social and demographic factors.”

“We found little evidence that Internet sales of pharmaceuticals and errors by doctors and patients–factors commonly cited in the media — have played a significant role,” Prof. King adds.

The findings point to a complicated “epidemic” in which physicians, users, the health care system, and the social environment all play a role, according to the researchers.

“Our work provides a reliable summary of the possible causes of the epidemic of opioid overdoses, which should be useful for clinicians and policy makers in North America in figuring out what further research needs to be done, and what strategies might or might not be useful in reducing future mortality,” says King. “And as efforts are made to increase access to prescription opioids outside of North America, our findings might be useful in preventing other countries from following the same path as the U.S. and Canada.”

The results of this research are published in the American Journal of Public Health and can be read here.

“These determinants operate independently but interact in complex ways that vary according to geography and population, making generalization from single studies inadvisable. Researchers in this area face significant methodological difficulties; most of the studies in our review were ecological or observational and lacked control groups or adjustment for confounding factors; thus, causal inferences are difficult.”
Wow, so pretty much a complete lack of science.

Mr. Place’s quotation above is but one (albeit an essential one) of the many misleading inferences that riddle this “Systematic Review.” Several others: 1) The title refers to “Increased Opioid-Related Mortality in the United States and Canada,” but read a little further, and we learn that, “National data [for this type of mortality] are UNavailable for Canada…” (And what exactly is the relevance of mortality statistics from one province out of Canada’s ten?) 2) The selection process described under “Methods” is fraught with holes although readers are presumably meant to be reassured because, on a regular basis, “…all disagreements [between… Read more »
