1) Drugs, Guns and Cars: How Far We Have Come to Improve Safety in the United States; Yet We Still Have Far to Go.

Dodington J, Violano P, Baum CR, Bechtel K.

Pediatr Res. 2016 Sep 27. doi: 10.1038/pr.2016.193. [Epub ahead of print] Review.

Comment: Review of safety efforts in public health.

2) Primary Care Patient Experience with Naloxone Prescription.

Behar E, Rowe C, Santos GM, Murphy S, Coffin PO.

Ann Fam Med. 2016 Sep;14(5):431-6. doi: 10.1370/afm.1972.

Comment: This is a partner paper to the study results reported a couple of months ago. Mixed methods interviews with 60 randomly selected patients on longterm opioid therapy for chronic pain who had been prescribed naloxone. The co-prescribing effort reached a population that was not really accessing naloxone through other community distribution sites in San Francisco. Some reported improved safety with opioids since receiving naloxone and none reported more high-risk use behaviors. About half of those who had overdosed denied “overdose” and described it as a bad reaction.

3) Opioid Overdose Experience, Risk Behaviors, and Knowledge in Drug Users from a Rural versus an Urban Setting.

Dunn KE, Barrett FS, Yepez-Laubach C, Meyer AC, Hruska BJ, Petrush K, Berman S, Sigmon SC, Fingerhood M, Bigelow GE.

J Subst Abuse Treat. 2016 Dec;71:1-7.

Comment: Can’t access the paper, but the abstract suggests higher rates of overdose among rural drug users versus urban, while there were fewer overdose risk behaviors among rural users (potentially raising concerns about our risk behaviors, which were retrospectively developed).

4) Longitudinal changes in psychological distress in a cohort of people who inject drugs in Melbourne, Australia.

Scott N, Carrotte ER, Higgs P, Cogger S, Stoové MA, Aitken CK, Dietze PM.

Drug Alcohol Depend. 2016 Sep 11;168:140-146. doi: 10.1016/j.drugalcdep.2016.08.638. [Epub ahead of print]

Comment: People who inject drugs have more psychological distress than the general population. Not surprised that intentional overdose (i.e. suicide attempt) is associated with psychological distress.

5) Notes from the Field: Furanyl-Fentanyl Overdose Events Caused by Smoking Contaminated Crack Cocaine - British Columbia, Canada, July 15-18, 2016.

Klar SA, Brodkin E, Gibson E, Padhi S, Predy C, Green C, Lee V.

MMWR Morb Mortal Wkly Rep. 2016 Sep 23;65(37):1015-1016. doi: 10.15585/mmwr.mm6537a6.

Comment: Fentanyl in crack. Ugh.

1. Patterns and correlates of non-fatal heroin overdose at 11-year follow-up: Findings from the Australian Treatment Outcome Study.

Darke S, Marel C, Mills KL, Ross J, Slade T, Burns L, Teesson M.

Drug Alcohol Depend. 2014 Sep 16. [Epub ahead of print]

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.

Simonson W.

Geriatr Nurs. 2014 Sep-Oct;35(5):381-2.

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.

Rudd RA, Paulozzi LJ, Bauer MJ, Burleson RW, Carlson RE, Dao D, Davis JW, Dudek J, Eichler BA, Fernandes JC, Fondario A, Gabella B, Hume B, Huntamer T, Kariisa M, Largo TW, Miles J, Newmyer A, Nitcheva D, Perez BE, Proescholdbell SK, Sabel JC, Skiba J, Slavova S, Stone K, Tharp JM, Wendling T, Wright D, Zehner AM.

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.

Better late than never, right? 24 papers over two months.

1) Overdose rescues by trained and untrained participants and change in opioid use among substance-using participants in overdose education and naloxone distribution programs: a retrospective cohort study.

Doe-Simkins M, Quinn E, Xuan Z, Sorensen-Alawad A, Hackman H, Ozonoff A, Walley AY.

BMC Public Health. 2014 Apr 1;14(1):297. [Epub ahead of print]

Comments: Sometimes naloxone is used by bystanders who have not been formally educated (or “trained”) in administering naloxone. This innovative analysis suggests that the untrained witness does a good job in lay naloxone administration.

2) Easy-to-use overdose antidote earns fast-track approval.

Kuehn BM.

JAMA. 2014 Apr 23-30;311(16):1600. doi: 10.1001/jama.2014.4483. No abstract available.

Comments: The naloxone auto-injector – Evzio – has been approved and is expected to be available this summer.

3) Research gaps on methadone harms and comparative harms: findings from a review of the evidence for an american pain society and college on problems of drug dependence clinical practice guideline.

Weimer MB, Chou R.

J Pain. 2014 Apr;15(4):366-76. doi: 10.1016/j.jpain.2014.01.496.

Comments: Basic summary is that it’s not entirely clear why there was such a surge in methadone-related deaths in the early part of the 2000s. It’s important to remember that the surge came after a surge in oxycontin-related deaths, when many payers shifted their preferred agent from oxycontin to methadone. Mortality data seems to follow the trend of the most prescribed agent.

4) Paramedic-supplied 'Take Home' Naloxone: protocol for cluster randomised feasibility study.

Moore C, Lloyd G, Oretti R, Russell I, Snooks H.

BMJ Open. 2014 Mar 20;4(3):e004712. doi: 10.1136/bmjopen-2013-004712.

Comments: Outstanding, innovative design to reach those at very high risk of future overdose events. I anxiously await results.

News: FDA denies Reckitt's request to block generic buprenorphine/naloxone tablets

The U.S. Food and Drug Administration has roundly denied all requests from Reckitt-Benckiser to block approval of generic buprenorphine/naloxone tablets. This request was made at the time when the monopoly on the product was ending and was based on risks of pediatric exposures that the company claimed were higher with the tablet than their new film product. The FDA provided an excellent review of the issues and rejected all components of the request.

This is an enormous relief for public health agencies providing buprenorphine services, many of which would have dropped buprenorphine services altogether or would have ceased to provide the buprenorphine/naloxone formulation due to cost.
