PubMed Update October/November 2016

43 papers this round, and there are some goodies in here for sure (don't miss #38!). Given the number and varied issues addressed, I divided them up into topic areas and, given the number on naloxone, I divided up the naloxone topic areas as well.

Naloxone interventions

Primary care

1) Co-prescription of naloxone as a Universal Precautions model for patients on chronic opioid therapy-Observational study.

Takeda MY, Katzman JG, Dole E, Bennett MH, Alchbli A, Duhigg D, Yonas H.

Subst Abus. 2016 Apr 19:1-6. [Epub ahead of print]

Comment: A pilot of naloxone co-prescribing.

2) Attitudes Toward Naloxone Prescribing in Clinical Settings: A Qualitative Study of Patients Prescribed High Dose Opioids for Chronic Non-Cancer Pain.

Mueller SR, Koester S, Glanz JM, Gardner EM, Binswanger IA.

J Gen Intern Med. 2016 Oct 31. [Epub ahead of print]

Comment: Shows that naloxone for patients prescribed opioids must be appropriately framed.

3) Acceptability of Naloxone Co-Prescription Among Primary Care Providers Treating Patients on Long-Term Opioid Therapy for Pain.

Behar E, Rowe C, Santos GM, Coffa D, Turner C, Santos NC, Coffin PO.

J Gen Intern Med. 2016 Nov 4. [Epub ahead of print]

Comment: When actually implemented, providers really like adding naloxone to opioid-related care. One of five papers out of the Naloxone for Opioid Safety Evaluation of a naloxone co-prescribing study in San Francisco.

PubMed Update September 2016

15 papers this month.

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.

PubMed Update August 2016

A robust 20 papers this month. There are some excellent manuscripts this month, including several on fentanyl. I want to draw particular attention to a few papers that will be important reads for some of you: #1 addresses concurrent use of methamphetamine with heroin, #12 explores different “types” of opioid overdose, #17 reviews the foundational papers upon which much overdose research/knowledge today is based, and #19 compares deaths due to heroin to those due to prescription opioids.

1) Prevalence and Correlates of Heroin-Methamphetamine Co-Injection Among Persons Who Inject Drugs in San Diego, California, and Tijuana, Baja California, Mexico.

Meacham MC, Strathdee SA, Rangel G, Armenta RF, Gaines TL, Garfein RS.

J Stud Alcohol Drugs. 2016 Sep;77(5):774-81.

Comments: Really interesting results with regard to methamphetamine – co-use of methamphetamine increased overdose risk in San Diego but not Tijuana, suggesting that risk may have been behavioral rather than pharmacologic.

2) Combating Opioid Overdose With Public Access to Naloxone.

Mitchell KD, Higgins LJ.

J Addict Nurs. 2016 Jul-Sep;27(3):160-79. doi: 10.1097/JAN.0000000000000132.

Comments: Review of naloxone literature with an eye toward how it influences nursing.

3) Prescription opioids prior to injection drug use: Comparisons and public health implications.

Al-Tayyib AA, Koester S, Riggs P.

Addict Behav. 2016 Aug 19. pii: S0306-4603(16)30296-9. doi: 10.1016/j.addbeh.2016.08.016. [Epub ahead of print]

Comments: Those who initiated injection with prescription opioids were higher risk than those who started with heroin in the Denver Colorado’s NHBS cohort.

4) Awareness and Attitudes Toward Intranasal Naloxone Rescue for Opioid Overdose Prevention.

Kirane H, Ketteringham M, Bereket S, Dima R, Basta A, Mendoza S, Hansen H.

J Subst Abuse Treat. 2016 Oct;69:44-9. doi: 10.1016/j.jsat.2016.07.005. Epub 2016 Jul 18.

Comments: Investigators asked patients and providers how they thought things *would* change if they gave/received naloxone kits and found quite a few thought use would increase. In contrast, looking at what “did” happen suggests the opposite (see next month’s PubMed Update).

PubMed Update July 2016

11 papers this month, including an announcement that naloxone is now over-the-counter in Australia.

1) Factors associated with knowledge of a Good Samaritan Law among young adults who use prescription opioids non-medically.

Evans TI, Hadland SE, Clark MA, Green TC, Marshall BD.

Harm Reduct J. 2016 Jul 26;13(1):24. doi: 10.1186/s12954-016-0113-2.

Comments: Less than half knew about it.

2) Reasons for Benzodiazepine Use Among Persons Seeking Opioid Detoxification.

Stein MD, Kanabar M, Anderson BJ, Lembke A, Bailey GL.

J Subst Abuse Treat. 2016 Sep;68:57-61. doi: 10.1016/j.jsat.2016.06.008. Epub 2016 Jun 16.

Comments: Important work, as there’s an effort to also reduce benzodiazepine prescribing among people who are on opioids. Understanding the drivers of BDZ use should be helpful in structuring interventions. Anxiety and managing opioid withdrawal were two main reasons.

3) Trends in Methadone Distribution for Pain Treatment, Methadone Diversion, and Overdose Deaths - United States, 2002-2014.

Jones CM, Baldwin GT, Manocchio T, White JO, Mack KA.

MMWR Morb Mortal Wkly Rep. 2016 Jul 8;65(26):667-71. doi: 10.15585/mmwr.mm6526a2.

Comments: Interesting analysis of methadone prescribing, overdose, and diversion. It seems that efforts to reduce methadone, beginning in 2006, corresponded with reduced diversion and overdose; unfortunate that opioid overdose death overall continued to escalate.

4) Determinants of willingness to enroll in opioid agonist treatment among opioid dependent people who inject drugs in Ukraine.

Makarenko I, Mazhnaya A, Polonsky M, Marcus R, Bojko MJ, Filippovych S, Springer S, Dvoriak S, Altice FL.

Drug Alcohol Depend. 2016 Aug 1;165:213-20. doi: 10.1016/j.drugalcdep.2016.06.011. Epub 2016 Jun 17.

Comments: Barriers to enrolling in agonist treatment in Ukraine.

PubMed Update June 2016

Summer holiday. A mere 10 articles this month!

1) Community pharmacist knowledge, attitudes and confidence regarding naloxone for overdosereversal.

Nielsen S, Menon N, Larney S, Farrell M, Degenhardt L.

Addiction. 2016 Jul 1. doi: 10.1111/add.13517. [Epub ahead of print]

Comment: Most pharmacists in Australia would provide naloxone, but a minority feel comfortable selecting patients and educating about naloxone use and overdose.

2) Nonrandomized Intervention Study of Naloxone Coprescription for Primary Care Patients Receiving Long-Term Opioid Therapy for Pain.

Coffin PO, Behar E, Rowe C, Santos GM, Coffa D, Bald M, Vittinghoff E.

Ann Intern Med. 2016 Jun 28. doi: 10.7326/M15-2771. [Epub ahead of print]

Comment: Naloxone can be successfully prescribed to primary care patients on longterm opioids for chronic pain, and receipt of naloxone is associated with a remarkable reduction in opioid-related emergency department visits.

3) Opioid Use Disorders.

Sharma B, Bruner A, Barnett G, Fishman M.

Child Adolesc Psychiatr Clin N Am. 2016 Jul;25(3):473-87. doi: 10.1016/j.chc.2016.03.002. Epub 2016 Apr 9. Review.

Comment: Review of opioid use disorder and treatments.

4) Predictors of seeking emergency medical help during overdose events in a provincial naloxone distribution programme: a retrospective analysis.

Ambrose G, Amlani A, Buxton JA.

BMJ Open. 2016 Jun 21;6(6):e011224. doi: 10.1136/bmjopen-2016-011224.

Comment: Respondents administering naloxone to overdoses on the street were more likely to call for medical assistance than those doing so in a private residence. This makes a lot of sense. Imaging if giving a breathing treatment for asthma in a home versus on the street – the latter setting is more likely to result in seeking assistance.

PubMed Update May 2016

19 this month. Enjoy!

1) Methadone-Related Overdose Deaths in a Liberal Opioid Maintenance Treatment Programme.

4) Patient Characteristics and Outcomes in Unintentional, Non-fatal Prescription Opioid Overdoses: A Systematic Review.

Elzey MJ, Barden SM, Edwards ES.

Pain Physician. 2016 May;19(4):215-28.

Comments: Non-fatal events are far more common, not well-predicted by risk factors, and in need of additional research.

5) Incorporation of poison center services in a state-wide overdose education and naloxone distribution program.

Doyon S, Benton C, Anderson BA, Baier M, Haas E, Hadley L, Maehr J, Rebbert-Franklin K, Olsen Y, Welsh C.

Am J Addict. 2016 Jun;25(4):301-6. doi: 10.1111/ajad.12384. Epub 2016 May 24.

Comments: Interesting case series of naloxone reversals reported to poison control. They report a 75.6% “response rate” although some of the remainder was “unknown” and was there were only 2 deaths among 78 cases, suggesting a rate closer to 97.5%. Response rate to heroin was higher than for prescription opioids. Of the 43 suspected heroin events, 31 went to the ED, 25 were discharged, and 5 required ICU care. Of 31 suspected prescription opioid 20 went to the ED, 9 were discharged, and 6 required ICU care. This is consistent with the more complicated nature of prescription opioid overdose.

6) Police Officers Can Safely and Effectively Administer Intranasal Naloxone.
