Comment: Doesn’t really remove methadone, so not useful in an overdose but also not problematic for patients on methadone undergoing light-chain removal.

Madah-Amiri D, Clausen T, Lobmaier P.
Drug Alcohol Depend. 2016 Apr 14. pii: S0376-8716(16)30034-5. doi: 10.1016/j.drugalcdep.2016.04.007. [Epub ahead of print]

Acad Emerg Med. 2016 Apr 21. doi: 10.1111/acem.12992. [Epub ahead of print]
Comment: Intriguing look at ED policies in New England. 18% had an opioid screening tool, 78% used the PDMP, 41% alerted the primary doctor when prescribing opioids, 70% gave substance use treatment referrals, and 12% offered take-home naloxone.

Pade P, Fehling P, Collins S, Martin L.

Comment: Naloxone in a residential treatment program. Hopefully the first bit of data with much more to come.

Comment: New Mexico study of 164 chronic pain patients on opioids who were provided naloxone. There were no overdoses.

Friedman MS, Manini AF.
J Med Toxicol. 2016 Apr 15. [Epub ahead of print]
Comment: Fascinating abstract – I don’t have full access. They set up “naloxone criteria” of (1) respiratory rate <12, miotic pupils, or drug paraphernalia, and (2) altered mental status by AVPU or GCS and then looked to see if those criteria predicted a beneficial effect of naloxone. They did – with an OR of 7 and 83% sensitivity. Miotic pupils were the best predictor of a response to naloxone. Authors also found that naloxone was underutilized – in only 44.2% of cases where it may have been beneficial. This is a fascinating area, as we don’t yet understand the reasons why naloxone is or is not administered in emergency services.

Darke S, Duflou J.
Addiction. 2016 Apr 15. doi: 10.1111/add.13429. [Epub ahead of print]
Comment: 6-MAM, the best way to confirm heroin as a cause of overdose death, is only present if the death occurs in under 30 minutes. In this study, 6-MAM was present in 43% of heroin overdose cases, suggesting that most people took longer to expire.

Lewis DA, Park JN, Vail L, Sine M, Welsh C, Sherman SG.
Am J Public Health. 2016 Apr 14:e1-e4. [Epub ahead of print]
Comment: Distribution program increased self-efficacy.

Chronister KJ, Lintzeris N, Jackson A, Ivan M, Dietze P, Lenton S, Kearley J, van Beek I.
Drug Alcohol Rev. 2016 Apr 13. doi: 10.1111/dar.12400. [Epub ahead of print]
Comment: First data on an Australian naloxone program. 83 people given naloxone. Among the 42% completing follow-up, 30 overdoses were successfully reversed and participants still felt informed and able to use naloxone.

Hoback J.
State Legis. 2016 Apr;42(4):9-13. No abstract available.
Comment: On a quick glance, seems a bit inflammatory.

Harned M, Sloan P.
Expert Opin Drug Saf. 2016 Apr 26:1-8. [Epub ahead of print]
Comment: Prospective trials are needed to evaluate longterm opioid therapy for chronic pain.

Lee JD, Friedmann PD, Kinlock TW, Nunes EV, Boney TY, Hoskinson RA Jr, Wilson D, McDonald R, Rotrosen J, Gourevitch MN, Gordon M, Fishman M, Chen DT, Bonnie RJ, Cornish JW, Murphy SM, O'Brien CP.
N Engl J Med. 2016 Mar 31;374(13):1232-42. doi: 10.1056/NEJMoa1505409.
Comment: Pretty good data on extended-release naltrexone and low overdose risk. Unfortunately, overdose wasn’t specifically asked about, but instead was treated as any other adverse events in a clinical trial and had to be reported by the participants.

Yablonsky TA, Thompson GL.
W V Med J. 2016 Mar-Apr;112(2):16-7. No abstract available.
Comment: Can’t access, but there are a lot.

Comment: Lockboxes.

Comment: This is apparently about police and naloxone.

Rudd RA, Aleshire N, Zibbell JE, Gladden RM.
MMWR Morb Mortal Wkly Rep. 2016 Jan 1;64(50-51):1378-82. doi: 10.15585/mmwr.mm6450a3.
Comment: Really well done. Discusses opioids in a sophisticated and honest manner. Impressive work from the CDC.

Ann Intern Med. 2016 Jan 5;164(1):1-9. doi: 10.7326/M15-0038. Epub 2015 Dec 29.
Comment: Patients who have an overdose usually continue to receive opioids. If opioids stop, they have a lower risk of recurrent overdose.

Sgarlato A, deRoux SJ.
Forensic Sci Med Pathol. 2015 Sep;11(3):388-94. doi: 10.1007/s12024-015-9699-z. Epub 2015 Aug 2.
Comment: 36.7% of decedents had a valid opioid prescription; benzos were involved in 68.4% of cases with alprazolam the most common (35.1%).

Comment: Heavy drinking was associated with overdose (OR 1.6).
