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.

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]

Emergency department

4) Emergency Department-based Opioid Harm Reduction: Moving Physicians From Willing to Doing.

Samuels EA, Dwyer K, Mello MJ, Baird J, Kellogg AR, Bernstein E.

Acad Emerg Med. 2016 Apr;23(4):455-65. doi: 10.1111/acem.12910.

Comment: There needs to be some high-level leadership in emergency medicine before we see real movement from emergency docs.

5) Why is it so hard to implement change? A qualitative examination of barriers and facilitators to distribution of naloxone for overdose prevention in a safety net environment.

Drainoni ML, Koppelman EA, Feldman JA, Walley AY, Mitchell PM, Ellison J, Bernstein E.

BMC Res Notes. 2016 Oct 18;9(1):465.

Comment: If you offer it from emergency departments, you’ll get reasonable uptake. Interesting in the context of our other ED naloxone papers from this month.

Corrections

7)  Randomized controlled pilot trial of naloxone-on-release to prevent post-prison opioid overdose deaths.

Parmar MK, Strang J, Choo L, Meade AM, Bird SM.

Addiction. 2016 Oct 24. doi: 10.1111/add.13668. [Epub ahead of print]

Comment: Interesting piece on the N-ALIVE trial, which was possibly our last real hope for a definitive randomized controlled trial of naloxone provision. Unfortunately it didn’t work out, but there is still room for some innovative trial designs to try to get close to such definitive data.

8) Stakeholder perceptions and operational barriers in the training and distribution of take-home naloxone within prisons in England.

Sondhi A, Ryan G, Day E.

Harm Reduct J. 2016 Feb 3;13:5. doi: 10.1186/s12954-016-0094-1.

Comment: If you don’t give them naloxone, they don’t go get it themselves. This is like a flu vaccination. People don’t go out of their way for preventive interventions.

Distribution program

10) Process evaluation of the Prevent Overdose in Toronto (POINT) program.

Leece P, Gassanov M, Hopkins S, Marshall C, Millson P, Shahin R.

Can J Public Health. 2016 Oct 20;107(3):e224-e230. doi: 10.17269/cjph.107.5480.

Comment: As above.

Law enforcement / emergency medical service response

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

Fisher R, O'Donnell D, Ray B, Rusyniak D.

Prehosp Emerg Care. 2016 Nov-Dec;20(6):675-680.

Kolinsky D, Keim SM, Cohn BG, Schwarz ES, Yealy DM.

J Emerg Med. 2016 Oct 18. pii: S0736-4679(16)30777-6. doi: 10.1016/j.jemermed.2016.09.015. [Epub ahead of print]

Comment: Probably per this paper. Yes per the parallel one that came out this month.

Miscellaneous

16) Can Naloxone Be Used to Treat Synthetic Cannabinoid Overdose?

Jones JD, Nolan ML, Daver R, Comer SD, Paone D.

Biol Psychiatry. 2016 Aug 18. pii: S0006-3223(16)32710-X. doi: 10.1016/j.biopsych.2016.08.013. [Epub ahead of print] No abstract available.

Comment: Interesting that naloxone seemed to help in these cases, in the absence of presence of opioids. There is an interaction between the opioid and cannabinoid receptor systems (which was actually an element of my undergraduate work with cannabinoids and pain – a theory suggested by the late J Michael Walker from Brown University).

Prescription opioids and chronic pain

17) Prescription drug abuse - A timely update.

Monheit B, Pietrzak D, Hocking S.

Aust Fam Physician. 2016 Dec;45(12):862-866.

Comment: Prescription opioids in Australia. And buprenorphine is really safe.

18) Opioid Misuse/Abuse and Quality Persistent Pain Management in Older Adults.

Chang YP, Compton P.

J Gerontol Nurs. 2016 Dec 1;42(12):21-30. doi: 10.3928/00989134-20161110-06.

Comment: Hopefully the new efforts at opioid prescribing will help. I remain concerned that, without substantial investments in funding other pain management strategies, feelings of patient abandonment will worsen.

19) Challenges to Treatment of Chronic Pain and Addiction During the "Opioid Crisis".

Krashin D, Murinova N, Sullivan M.

Curr Pain Headache Rep. 2016 Dec;20(12):65. Review.

Comment: Per title.

20) Turning the Tide or Riptide? the Changing Opioid Epidemic.

Kertesz SG.

Subst Abus. 2016 Nov 18:0. [Epub ahead of print]

Comment: A pointed analysis of issues with the continued focus on opioid prescribing, when reforms have been followed by explosions in the use and consequences of street opioids.

21) Risk factors for opioid overdose and awareness of overdose risk among veterans prescribed chronic opioids for addiction or pain.

Wilder CM, Miller SC, Tiffany E, Winhusen T, Winstanley EL, Stein MD.

J Addict Dis. 2016;35(1):42-51. doi: 10.1080/10550887.2016.1107264.

Comment: Everybody underestimates their overdose risk. The next question is what does this mean (e.g. does this apply to most medical disorders?) and what do we do with the information?

22) Opioid Overdose: Risk Assessment and Mitigation in Outpatient Treatment.

Lin LA, Hosanagar A, Park TW, Bohnert AS.

J Addict Med. 2016 Nov/Dec;10(6):382-386.

Comment: Can’t access this case report of a patient with comorbid chronic pain and substance use disorder who had a heroin overdose.

23) Declines in Opioid Prescribing After a Private Insurer Policy Change - Massachusetts, 2011-2015.

MMWR Morb Mortal Wkly Rep. 2016 Oct 21;65(41):1125-1131. doi: 10.15585/mmwr.mm6541a1.

Comment: Opioid stewardship interventions reduced opioid prescribing in Massachusetts. No surprise there. But no analysis of what happened to patients who were no longer prescribed opioids. We’re in the midst of a crisis and really need to go further than just looking at opioid prescribing.

24) Management of patients with issues related to opioid safety, efficacy and/or misuse: a case series from an integrated, interdisciplinary clinic.

Becker WC, Merlin JS, Manhapra A, Edens EL.

Addict Sci Clin Pract. 2016 Jan 28;11(1):3. doi: 10.1186/s13722-016-0050-0.

Comment: It takes a lot of work to manage patients well; many providers do not have the resources to pull this off.

25) Efficacy and safety of two methadone titration methods for the treatment of cancer-related pain: The EQUIMETH2 trial (methadone for cancer-related pain).

Poulain P, Berleur MP, Lefki S, Lefebvre D, Chvetzoff G, Serra E, Tremellat F, Derniaux A, Filbet M; EQUIMETH2 Study Group..

27) Mandatory Provider Review And Pain Clinic Laws Reduce The Amounts Of Opioids Prescribed And Overdose Death Rates.

Dowell D, Zhang K, Noonan RK, Hockenberry JM.

Health Aff (Millwood). 2016 Oct 1;35(10):1876-1883.

Comment: Wow this is complicated. And I’m unsure that amalgamated national data can appropriately reflect the reasons for such complicated results. The real impact in terms of overdose mortality, if there is one, is from prescribed opioids. It seems a stretch to say these data show a reduction in overall opioid overdose mortality.

Toxicology reports:

28) Risk Factors for Mortality and Endotracheal Intubation after Methadone Intoxication.

Hassanian-Moghaddam H, Soltaninejad K, Shadnia S, Kabir A, Movahedi M, Mirafzal A.

Basic Clin Pharmacol Toxicol. 2016 Mar;118(3):231-7. doi: 10.1111/bcpt.12476.

Toce MS, Burns MM, O'Donnell KA.

Clin Toxicol (Phila). 2016 Oct 19:1-6. [Epub ahead of print]

Comment: Effects are similar to other opioids for infants/toddlers, and duration of observation required is dependent upon dose.

Drug Alcohol Depend. 2016 Oct 19;169:117-127. doi: 10.1016/j.drugalcdep.2016.10.015. [Epub ahead of print]

Comment: Yup, the United States has issues with providing appropriate treatments for opioid use disorder. These issues are multi-faceted, ranging from the unbelievable stigma faced by a person who even admits to any drug use in a medical setting, to the finance issues in a fragmented, barely hung together healthcare system slated to be further trampled in the next couple of years.

Epidemilogy / qualitative results

Acad Emerg Med. 2016 Oct 20. doi: 10.1111/acem.13121. [Epub ahead of print]

Comment: ICD coding for opioid poisoning in a safety net hospital detected only a quarter of opioid overdose cases, suggesting that surveillance of this issue based on billing codes in emergency departments may vastly underestimate the number of cases. It is also possible that there is huge variation in how cases are coded. Unfortunately, this is another strike against using “big data” in substance use research. The reasons for poor coding are many, including stigma.

38) Risk of fentanyl overdose among clients of the Sydney Medically Supervised Injecting Centre.

Latimer J, Ling S, Flaherty I, Jauncey M, Salmon AM.

Int J Drug Policy. 2016 Oct 14;37:111-114. doi: 10.1016/j.drugpo.2016.08.004. [Epub ahead of print]

Comment: Nice work by this team! Fentanyl injection had twice the risk of overdose of heroin injection and eight times the risk of injection other prescribed opioids. Although this is observational, it’s the first data we have to start to paint the picture.

39) Communicating risk in the context of methadone formulation changes: A qualitative study of overdose warning posters in Vancouver, Canada.

Markwick N, McNeil R, Anderson S, Small W, Kerr T.

Int J Drug Policy. 2016 Jan;27:178-81. doi: 10.1016/j.drugpo.2015.10.013. No abstract available.

Heimer R, Lyubimova A, Barbour R, Levina OS.

Int J Drug Policy. 2016 Jan;27:97-104. doi: 10.1016/j.drugpo.2015.10.001.

Comment: Methadone use has increased from 4% in 2010 to 53% in 2012/13, and its use is associated with fewer HIV risk behaviors than heroin use.

41) Do drug seizures predict drug-related emergency department presentations or arrests for drug use and possession?

Wan WY, Weatherburn D, Wardlaw G, Sarafidis V, Sara G.

Int J Drug Policy. 2016 Jan;27:74-81. doi: 10.1016/j.drugpo.2015.09.012.
