Comment: This study (the ATOS) and the team of investigators have produced some of the most powerful and useful data in substance use research. Once again they have delved into heroin overdose by following treatment patients 11 years out. At least 10.2% of the cohort had died by that time and an additional 9.4% were unaccounted for. Among the 70.1% interviewed, 67.5% had overdosed, 24.4% had experienced five or more overdoses (again suggesting that there are “overdosers” out there who are at very elevated risk of the event). In the past year before the follow-up visit, 4.9% had overdosed (11.8% of those who had used heroin in that period), 95.2% of whom had overdosed previously. Those who overdosed were more likely to report higher levels of non-heroin opiate use, as well as benzodiazepine, cocaine, and methamphetamine use.

2. A new naloxone auto-injection device to treat opioid overdose.

Comment: A review of the role of take-home naloxone in the form of the new autoinjector.

3. Increases in heroin overdose deaths - 28 States, 2010 to 2012.

MMWR Morb Mortal Wkly Rep. 2014 Oct 3;63(39):849-54.

Comment: This report demonstrates declining prescription opioid deaths (-6.6%), but heroin deaths increased so much (+101.7%) that the data actually demonstrate an overall increase in opioid overdose mortality from 2010 to 2012 (+4.3%). There is disagreement as to what is driving the increase in heroin use and overdose. Is it an inevitable consequence of increased availability of opioids? Or is it the result of growing restrictions on access to those opioids? Clearly there are elements of both, leaving us with conflicting duties when it comes to managing those already reliant upon prescription opioids. Western medical ethics is clear on this point: our patient is the person we treat, who may have been harmed by the very same prescribing behavior we are now trying to change and who may be further harmed by those changes. If we truly believe that this epidemic is “iatrogenic” (i.e. caused by medical care, akin to a surgeon leaving scissors in an abdomen), then we have to be extremely cautious and thoughtful in fixing the problem and we can never abandon the patient.

4. Working together: Expanding the availability of naloxone for peer administration to prevent opioid overdose deaths in the Australian Capital Territory and beyond.

Lenton S, Dietze P, Olsen A, Wiggins N, McDonald D, Fowlie C.

Drug Alcohol Rev. 2014 Oct 1. doi: 10.1111/dar.12198. [Epub ahead of print]

Comment: It's taken an incredibly long time for take-home naloxone to reach Australia, especially given how innovative that country has been with respect to managing drug policy and overdose.

5. Responding to opioid overdose in Rhode Island: where the medical community has gone and where we need to go.

Green TC, Bratberg J, Dauria EF, Rich JD.

R I Med J (2013). 2014 Oct 1;97(10):29-33.

Comment: The first of three articles in this post from Rhode Island, US, which has been facing a surge in opioid overdose deaths and has been responding with expanded naloxone treatment availability. This and the next two articles are free at: http://rimed.org/rimedicaljournal-2014-10.asp.
