Preventing deaths from rising opioid overdose in the US - the promise of naloxone antidote in community-based naloxone take-home programs

Antidotes in Clinical Toxicology-Critical Review

Poisoning and overdose are very important aspects in medicine and toxicology. Chemical weapons pose a threat to civilians, and emergency medicine principles must be followed when dealing with patients who have been poisoned or overdosed. Antidotes have been used for centuries and modern research has led to the development of new antidotes that can accelerate the elimination of toxins from the body. Although some antidotes have become less relevant due to modern intensive care techniques, they can still save lives or reduce the severity of toxicity. The availability of antidotes is crucial, especially in developing countries where intensive care facilities may be limited. This article aims to provide information on specific antidotes, their recommended uses, and potential risks and new uses. In the case of poisoning, supportive therapies are most often used; however, in many cases, the administration of an appropriate antidote saves the patient's life. In this review, we reviewed the literature on selected antidotes used in the treatment of poisonings. We also characterised the antidotes (bio)chemically. We described the cases in which they are used together with the dosage recommendations. We also analysed the mechanisms of action. In addition, we described alternative methods of using a given substance as a drug, an example of which is N-acetylcysteine, which can be used in the treatment of COVID-19. This article was written as part of the implementation of the project of the Polish Ministry of Education and Science, "Toxicovigilance, poisoning prevention, and first aid in poisoning with xenobiotics of current clinical importance in Poland", grant number SKN/SP/570184/2023.

'It's the same thing as giving them CPR training': rural first responders' perspectives on naloxone

The Substance Abuse and Mental Health Services Administration’s (SAMHSA) Harm Reduction grant program expanded access to several harm reduction strategies to mitigate opioid overdose fatalities, including expanding access to naloxone. Interviews with first responders in a frontier and remote (FAR) state were conducted to understand their job responsibilities in relation to overdose response and prevention and their perceptions of training laypersons to administer naloxone. This study includes 22 interviews with law enforcement, EMS and/or fire personnel, and members of harm reduction-focused community organizations. The study finds widespread support for increasing access to naloxone and training laypersons in naloxone administration throughout Montana, due to rural first responders’ inability to meet the needs of residents and an overall lack of resources to address addiction and the effects of fentanyl. Participants from harm reduction-focused community organizations convey support for training lay persons, but also illuminate that real and perceived cultural opposition to harm reduction strategies could reduce the likelihood that laypeople enroll in naloxone training. This study adds to the literature because it focuses on first responders in a FAR area that would benefit from layperson naloxone education and administration training due to its geographic expansiveness and the area’s overall lack of access to medications for opioid use disorder or other treatment services. Expanding harm reduction approaches, like increasing access and training laypersons to administer naloxone, might be FAR residents’ best chance for surviving an opioid overdose.

Use and Perceptions of Opioids Versus Marijuana among Cancer Survivors

Public health concerns regarding opioids and marijuana have implications for their medical use. This study examined use motives and perceived barriers in relation to opioid and marijuana use and interest in use among US adult cancer survivors. Self-administered surveys were distributed using social media to assess use motives and perceived barriers among participants living with cancer. Overall, 40.9% of cancer survivors reported current (past 30-day) use of opioids, 42.5% used marijuana, and 39.7% used both. The most common use motives for either/both drugs were to cope with pain and stress/anxiety (>70%). Highest-rated barriers to using either/both drugs were missing symptoms of worsening illness and not wanting to talk about their symptoms. Controlling for sociodemographics, binary logistic regression indicated that current opioid use was associated with reporting greater barriers to use (OR = 1.17, p = .011; Nagelkerke R-square = .934) and that current marijuana use was associated with reporting greater barriers to use (OR = 1.37, p = .003; Nagelkerke R-square = .921). Cancer survivors report various use motives and barriers to use regarding opioids and marijuana. While use motives and barriers for both drugs were similar, these constructs were differentially associated with use and interest in use across drugs. Understanding patients' perceptions about opioids and marijuana is an essential component to effectively manage symptoms related to a cancer diagnosis and improve quality of life for cancer survivors.

Modeling dynamics of fatal opioid overdose by state and across time

Opioid overdose fatalities include deaths from natural opioids (morphine and codeine), semi-synthetic opioids (oxycodone, hydrocodone), synthetic opioids (prescription and illicit fentanyl, tramadol), methadone, and heroin. From 1999 to 2017, there were 702,568 drug overdose deaths in the U.S., with 399,230 attributed to opioids. This study aimed to assess the dynamics of opioid related fatalities throughout the U.S. from 2006-2016. This study is a secondary analysis of data obtained through the Kaiser Family Foundation's analysis of Centers for Disease Control and Prevention data, 1999-2016. The data obtained were from all 50 states and the District of Columbia. A total of 272,130 individuals were included in the analysis. This represents the number of opioid overdose deaths in the United States from 2006-2016. Descriptive analysis of overall rates was conducted and mapped for visualization. Novel predictive models of increase for each drug overdose category were developed and used to calculate rate changes. Finally, the elasticity of change in rate for each drug category was calculated annually for the past 11 years. The highest rate of opioid overdose-related death occurred in West Virginia (40.03 per 100,000). In our secondary analysis, we explored the change in the rate of opioid-related deaths from 2015 to 2016. The changing dynamics of fatal opioid overdose at the state level is critical to guiding policy makers in addressing this crisis. Rates of fatal opioid overdose vary across the states, but we identify some trends. Regional differences are identified in states with the highest overdose rates from all opioids combined.

A brief telephone-delivered peer intervention to encourage enrollment in medication for opioid use disorder in individuals surviving an opioid overdose: Results from a randomized pilot trial

BACKGROUND

Medication for opioid use disorder (MOUD) can decrease the risk of opioid overdose (OOD) in individuals with opioid use disorder. Peer recovery support services (PRSS) are increasingly used to promote MOUD engagement but evidence of their efficacy is limited. This study's objective was to evaluate a single 20-minute telephone-delivered PRSS intervention for increasing MOUD enrollment and decreasing recurring OODs.

METHOD

This single-site, randomized controlled pilot trial enrolled adults, primarily recruited from a syringe service program, with an opioid-positive urine drug screen (UDS) reporting having been treated for an OOD within the past 6 months. Participants (N = 80) were randomized to PRSS (n = 40) or Control (n = 40) condition with all participants receiving personally-tailored OOD education and naloxone. Outcome measures obtained at 3 (n = 66), 6 (n = 58), and 12 (n = 44) months post-randomization included verified MOUD enrollment (primary), self-reported OOD, and opioid use assessed by self-report and UDS.

RESULTS

Through 12-month follow-up, 32.5 % of PRSS, compared to 17.5 % of Control participants enrolled in MOUD (X² = 2.4, p = 0.12; odds ratio = 2.27 (0.79-6.49)). PRSS participants were significantly less likely to have experienced an OOD through 12-month follow-up (12.5 % of PRSS participants, 32.5 % of Control, p = 0.03). No significant treatment effect was found for opioid use through 12-month follow-up as measured by either opioid-positive UDSs or self-reported past month opioid use days. Based on self-report, PRSS had good acceptability for both the interventionists and participants.

CONCLUSIONS

The results suggest that further development and testing of this PRSS telephone intervention to encourage MOUD enrollment and reduce OOD may be warranted.

Use and Perceptions of Opioids versus Marijuana among People Living with HIV

Objectives: In this study, we examined use of and interest in using opioids and marijuana, particularly in relation to use motives and perceived barriers to use, among people living with HIV (PLWH). Methods: We analyzed online survey data from 304 PLWH in the United States recruited via social media in Summer 2018. Results: In this sample (Mage = 30.86, 40.5% male, 64.5% white), 16.1% reported current (past 30-day) use of opioids, 18.1% marijuana, and 15.8% both. Participants reported more use motives and fewer barriers to using marijuana versus opioids (p's < .001). The most frequently endorsed motive for using either/both drugs were to cope with pain and stress/anxiety. Highest-rated barriers to using either/both drugs were missing symptoms of worsening illness and addiction concerns. Regression analyses indicated that current opioid use correlated with reporting greater opioid use motives; among past-month opioid nonusers, greater interest in using opioids correlated with greater opioid use motives. Current marijuana use correlated with reporting greater marijuana use motives and greater barriers; among past-month marijuana nonusers, greater interest in using marijuana correlated with greater marijuana use motives and fewer barriers. Conclusions: Use motives and barriers differentially correlated with use and interest in use across drugs, thereby indicating different intervention approaches to address appropriate use.

The Role of Emergency Medical Services in the Opioid Epidemic

The opioid crisis is an ongoing public health concern and EMS agencies are in a critical position to reach at-risk populations. The traditional role of EMS in treating acute opioid overdoses has expanded to include preventative strategies as well as long-term treatment and recovery options. EMS agencies are uniquely positioned to partner with local community resources and hospitals to combine efforts in implementing harm-reduction strategies.

"Those People Count": Naloxone Media Coverage in Mississippi

There is a movement to promote naloxone adoption by law enforcement and other stakeholders in the state of Mississippi. The purpose of this study is to understand how local media are framing the conversation about naloxone products, and to better understand how it might affect naloxone adoption among law enforcement. We searched for news articles published in Mississippi from January 2012 to July 2018 mentioning the words Narcan^® and/or naloxone. Four main themes emerged from 25 articles: (a) positive and informative discussion of naloxone, (b) full articles persuading readers to use and/or advocate the use of naloxone, (c) government or organizational effort to increase the availability and use of naloxone products, and (d) negative or misleading information about naloxone. Better efforts to disseminate correct and persuasive information about the drug will have a profound and positive effect on the opioid epidemic in Mississippi and in the United States.

Addiction stigma and the production of impediments to take-home naloxone uptake

Opioid overdose deaths are a major health issue in Australia and around the world. Programmes to provide opioid consumers with 'take-home' naloxone to reverse overdose exist internationally, but uptake by mainstream health services and consumers remains inconsistent. Researchers have identified a range of important educational, training and logistical impediments to take-home naloxone uptake and distribution, yet they have focused less on the social dynamics that can enhance or limit access, such as stigma. In this article, we also explore impediments to uptake, drawing on qualitative interview data gathered for an Australian research project on take-home naloxone. Mobilising a performative approach to stigma, we argue that overdose and prevention are shaped by the social dynamics of stigma and, as such, responsibility for dealing with overdose, as with take-home naloxone, should also be considered social (i.e. shared among peers, the public, communities and governments). Our interview data illuminate the various ways in which addiction stigma limits the possibilities and capacities of take-home naloxone and overdose prevention. First, we focus on how stigma may impede professional information provision about take-home naloxone by limiting the extent to which it is presented as a matter of interest for all opioid consumers, not just those who consume opioids illicitly. Second, we explore how stigma may limit the scale-up and expansion of programmes and access points. From here, we focus on how stigma co-constitutes the politics of overdose and prevention, rendering take-home naloxone ill-suited to many social settings of overdose. In closing, we point out that stigma is not just a post hoc impediment to access to and use of take-home naloxone but is central to opioid overdose production itself, and to effective prevention. While take-home naloxone is an excellent life-saving initiative, uncritically valorising it may divert attention from broader goals, such as the de-stigmatisation of drug consumption through decriminalisation, and other ambitious attempts to reduce overdose.

Implementation of Online Opioid Prevention, Recognition and Response Trainings for Laypeople: Year 1 Survey Results

BACKGROUND

This article reports on the first implementation of an online opioid-overdose prevention, recognition and response training for laypeople. The training was disseminated nationally in November 2014. Between 2000 and 2014, U.S. opioid deaths increased by 200%. The importance of complementary approaches to reduce opioid overdose deaths, such as online training, cannot be overstated.

OBJECTIVES

A retrospective evaluation was conducted to assess perceived knowledge, skills to intervene in an overdose, confidence to intervene, and satisfaction with the training.

MEASUREMENTS

Descriptive statistics were used to report sample characteristics, compare experiences with overdose and/or naloxone between subgroups, and describe participants' satisfaction with the trainings. Z-ratios were used to compare independent proportions, and paired t-tests were used to compare participant responses to items pre- and posttraining, including perceived confidence to intervene and perceived knowledge and skills to intervene successfully.

RESULTS

Between January and October 2015, 2,450 laypeople took the online training; 1,464 (59.8%) agreed to be contacted. Of these, 311 (21.2% of those contacted) completed the survey. Over 80% reported high satisfaction with content, format and mode of delivery and high satisfaction with items related to confidence and overdose reversal preparedness. Notably, 89.0% of participants felt they had the knowledge and skills to intervene successfully posttraining compared to 20.3% pretraining (z = -17.2, p <.001). Similarly, posttraining, 87.8% of participants felt confident they could successfully intervene compared to 24.4% pretraining (z = -15.9, p <.001).

CONCLUSIONS

This study demonstrates the effectiveness of the GetNaloxoneNow.org online training for laypeople.

Sociodemographic factors, prescription history and opioid overdose deaths: a statewide analysis using linked PDMP and mortality data

BACKGROUND

Opioid overdose deaths have continued to rise in Tennessee (TN) with fentanyl emerging as a major contributor. Current data are needed to identify at-risk populations to guide prevention strategies. We conducted a large statewide observational study among TN adult decedents (2013-2016) to evaluate the association of sociodemographic factors and prescribing patterns with opioid overdose deaths.

METHODS

Among drug overdose decedents identified using death certificate data (n = 5483), we used logistic regression to estimate adjusted odds ratios and 95% confidence intervals for characteristics associated with prescription opioid (PO) (excluding fentanyl), fentanyl, and heroin alone overdoses. Among decedents linked to TN's Prescription Drug Monitoring Database using deterministic algorithms, we obtained prescription history in the year before death (n = 3971), which was evaluated by type of overdose using descriptive statistics.

RESULTS

Younger, non-White decedents had lower odds of PO overdose, while females and benzodiazepines as a contributing cause were associated with increased odds of PO overdose. Younger age, Non-Hispanic Black race/ethnicity, greater than high school education, and cocaine/other stimulants as a contributing cause were associated with increased odds of fentanyl or heroin overdoses. Over 55% of PO, 39.2% of fentanyl, and 20.7% of heroin overdoses had an active opioid prescription at death. For PO, fentanyl, and heroin decedents, respectively, 46.0%, 30.5%, and 26.2% had an active prescription for benzodiazepines at death.

CONCLUSIONS

Prescription opioid overdose deaths were associated with different sociodemographic profiles and prescribing history compared to fentanyl and heroin overdose deaths in TN. Data can guide prevention strategies to reduce opioid overdose mortality.

Risks of opioid abuse among uninsured primary care patients utilizing a free clinic

The annual number of opioid prescriptions for pain relief has been increasing in the United States. This increase has raised concerns about prescription opioid abuse and overdose. The purpose of this study was to examine opioid risks (risk factors that increase the chance of opioid abuse) among uninsured primary care patients utilizing a free clinic. Data were collected using a self-administered paper survey in the waiting room of the free clinic from May to July 2017 (N = 506). Higher levels of somatic symptoms were associated with higher levels of opioid risks. U.S.-born English speakers had higher levels of opioid risk than non-U.S.-born English speakers and Spanish speakers. Being employed was associated with higher levels of opioid risk while attending college or being postcollegiate was related to lower levels of opioid risk. Research surrounding best practices, prescription trends, and population risk is vital in driving health and social policy. Further research would benefit from examining where people are obtaining opioids. In addition, further research on opioid abuse among Hispanic populations would be beneficial. Finally, future studies should examine how prescribing practices are different among free clinic health professionals in comparison to health care professionals working in-patient or at for-profit clinics.

Pharmacists' role in harm reduction: a survey assessment of Kentucky community pharmacists' willingness to participate in syringe/needle exchange

BACKGROUND

Pharmacists' role in harm reduction is expanding in many states, yet there are limited data on pharmacists' willingness to participate in harm reduction activities. This study assessed community pharmacists' willingness to participate in one harm reduction initiative: syringe/needle exchange.

METHODS

In 2015, all Kentucky pharmacists with active licenses were emailed a survey that examined attitudes towards participation in syringe/needle exchange. Response frequencies were calculated for community pharmacist respondents. Ordinal logistic regression estimated the impact of community pharmacist characteristics and attitudes on willingness to provide clean needles/syringes to people who inject drugs and to dispose of used syringes/needles, where both dependent variables were defined as Likert-type questions on a scale of 1 (not at all willing) to 6 (very willing).

RESULTS

Of 4699 practicing Kentucky pharmacists, 1282 pharmacists responded (response rate = 27.3%); the majority (n = 827) were community pharmacists. Community pharmacists were divided on willingness to provide clean needles/syringes, with 39.1% not willing (score 1 or 2 of 6) and 30% very willing (score 5 or 6 of 6). Few were willing to dispose of used needles/syringes, with only 18.7% willing. Community pharmacists who agreed that pharmacists could have significant public health impact by providing access to clean needles expressed 3.56 times more willingness to provide clean needles (95% CI 3.06-4.15), and 2.04 times more willingness to dispose of used needles (95% CI 1.77-2.35). Chain/supermarket pharmacists (n = 485, 58.6% of community pharmacies) were 39% less likely to express willingness to dispose of used needles (95% CI 0.43-0.87) when compared with independent community pharmacists (n = 342, 41.4% of community pharmacies). Independent pharmacists reported different barriers (workflow) than their chain/supermarket pharmacist colleagues (concerns of clientele).

CONCLUSIONS

Kentucky community pharmacists were more willing to provide clean needles than to dispose of used needles. Strategies to mitigate barriers to participation in syringe/needle exchange are warranted.

Do more robust prescription drug monitoring programs reduce prescription opioid overdose?

BACKGROUND AND AIMS

In the United States, overdose deaths attributed to opioid pain relievers (OPR) have quadrupled since 1999, prompting many states to adopt Prescription Drug Monitoring Programs (PMP). This study aimed to: (1) estimate the relationship of PMP strength with OPR overdose deaths across states and over time; (2) measure what threshold in PMP strength is associated with the greatest reduction in OPR overdose; and (3) assess the relationship of medical marijuana dispensaries with OPR overdose deaths.

DESIGN

Panel data from the Centers for Disease Control and Prevention's (CDC's) Wide-ranging Online Data for Epidemiologic Research database (WONDER) were analyzed using fixed effects to regress state-year death rates on an index variable compiled from the Prescription Drug Abuse Policy System (PDAPS) while controlling for PMP administration, demographic factors and laws that might affect OPR overdose.

SETTING AND PARTICIPANTS

Age-adjusted opioid overdose death rates for all 50 states and the District of Columbia between 1999 and 2014 for a total of 816 observations.

MEASUREMENTS

PMP strength was calculated using legal data compiled by the Prescription Drug Abuse Policy System (PDAPS). In addition to demographic controls, other covariates included laws that regulate pain clinics, access to naloxone, use of emergency services (Good Samaritan Laws) and medical marijuana.

FINDINGS

PMP strength was associated negatively with OPR overdose deaths. Every 1-point increase in PMP strength was associated with a 1% [95% confidence interval (CI) = 0.2-2%] reduction in overdose deaths. When collapsed into quartiles, PMPs in the third quartile were associated with an approximately 18% (95% CI = 1.6-29%) reduction in OPR overdose death rates compared with states without a PMP. States with medical marijuana dispensaries reported a 16% (95% CI = 1-30%) reduction in OPR overdoses.

CONCLUSIONS

US states that have more robust prescription drug monitoring programs have fewer prescription opioid overdose deaths than states with weaker PMPs. States with medical marijuana dispensaries also report fewer opioid overdose deaths than states without these.

Opiate addiction and overdose: experiences, attitudes, and appetite for community naloxone provision

BACKGROUND

More than 200 opiate overdose deaths occur annually in Ireland. Overdose prevention and management, including naloxone prescription, should be a priority for healthcare services. Naloxone is an effective overdose treatment and is now being considered for wider lay use.

AIM

To establish GPs' views and experiences of opiate addiction, overdose care, and naloxone provision.

DESIGN AND SETTING

An anonymous postal survey to GPs affiliated with the Department of Academic General Practice, University College Dublin, Ireland.

METHOD

A total of 714 GPs were invited to complete an anonymous postal survey. Results were compared with a parallel GP trainee survey.

RESULTS

A total of 448/714 (62.7%) GPs responded. Approximately one-third of GPs were based in urban, rural, and mixed areas. Over 75% of GPs who responded had patients who used illicit opiates, and 25% prescribed methadone. Two-thirds of GPs were in favour of increased naloxone availability in the community; almost one-third would take part in such a scheme. A higher proportion of GP trainees had used naloxone to treat opiate overdose than qualified GPs. In addition, a higher proportion of GP trainees were willing to be involved in naloxone distribution than qualified GPs. Intranasal naloxone was much preferred to single (P<0.001) or multiple dose (P<0.001) intramuscular naloxone. Few GPs objected to wider naloxone availability, with 66.1% (n = 292) being in favour.

CONCLUSION

GPs report extensive contact with people who have opiate use disorders but provide limited opiate agonist treatment. They support wider availability of naloxone and would participate in its expansion. Development and evaluation of an implementation strategy to support GP-based distribution is urgently needed.

Community pharmacist knowledge, attitudes and confidence regarding naloxone for overdose reversal

AIM

Given the potential to expand naloxone supply through community pharmacy, the aim of this study was to estimate Australian pharmacists': (1) level of support for overdose prevention, (2) barriers and facilitators for naloxone supply and (3) knowledge about naloxone administration.

DESIGN

Online survey from nationally representative sample of community pharmacies.

SETTING

Australia, September-November 2015.

PARTICIPANTS

A total of 1317 community pharmacists were invited to participate with 595 responses (45.1%).

MEASUREMENTS

We assessed attitudes towards harm reduction, support for overdose prevention, attitudes and knowledge about naloxone. We tested the association between attitudes towards harm reduction and different aspects of naloxone supply.

FINDINGS

Pharmacists were willing to receive training about naloxone (n = 479, 80.5%) and provide naloxone with a prescription (n = 537, 90.3%). Fewer (n = 234, 40.8%) were willing to supply naloxone over-the-counter. Positive attitudes towards harm reduction were associated with greater willingness to supply naloxone with a prescription [odds ratio (OR) = 1.15, 95% confidence interval (CI) = 1.11-1.19] and over-the-counter (OR = 1.13, 95% CI = 1.09-1.17). Few pharmacists were confident they could identify appropriate patients (n = 203, 34.1%) and educate them on overdose and naloxone use (n = 190, 31.9%). Mean naloxone knowledge scores were 1.8 (standard deviation 1.7) out of 5. More than half the sample identified lack of time, training, knowledge and reimbursement as potential barriers for naloxone provision.

CONCLUSION

Community pharmacists in Australia appear to be willing to supply naloxone. Low levels of knowledge about naloxone pharmacology and administration highlight the importance of training pharmacists about overdose prevention.

Take-home naloxone treatment for opioid emergencies: a comparison of routes of administration and associated delivery systems

INTRODUCTION

Naloxone reversal of opioid-induced respiratory depression outside of medical facilities has become more prevalent because of the escalating opioid epidemic in the USA. Take-home naloxone for treatment of opioid emergencies is now being recommended by numerous federal, state, and professional organizations. Areas covered: The scope of the opioid overdose epidemic is reviewed along with practical, clinical, regulatory, and usability considerations for take-home naloxone routes of administration currently available and associated delivery systems. Specific opioid-related factors are discussed in detail with emphasis placed on life-threatening respiratory depression and naloxone antagonism. A clinical overview, including pharmacokinetic and FDA approval information for each take-home naloxone product is discussed in detail as well as the impact of take-home naloxone in the community. Finally, given these products are to be used in a panic-stricken, life-threatening opioid emergency, an analysis of available usability data is provided with proposed directions for further study. Expert opinion: Based on the available clinical evidence, auto-injectable naloxone should be the preferred administration route for take-home naloxone treatment until additional safety, efficacy, and comparative outcomes data are available for unconventional routes of administration that unequivocally provide equal or superior results.

Refining Measurement of Substance Use Disorders Among Women of Child-Bearing Age Using Hospital Records: The Development of the Explicit-Mention Substance Abuse Need for Treatment in Women (EMSANT-W) Algorithm

Substance use disorder (SUD) in women of reproductive age is associated with adverse health consequences for both women and their offspring. US states need a feasible population-based, case-identification tool to generate better approximations of SUD prevalence, treatment use, and treatment outcomes among women. This article presents the development of the Explicit Mention Substance Abuse Need for Treatment in Women (EMSANT-W), a gender-tailored tool based upon existing International Classification of Diseases, 9th Edition, Clinical Modification diagnostic code-based groupers that can be applied to hospital administrative data. Gender-tailoring entailed the addition of codes related to infants, pregnancy, and prescription drug abuse, as well as the creation of inclusion/exclusion rules based on other conditions present in the diagnostic record. Among 1,728,027 women and associated infants who accessed hospital care from January 1, 2002 to December 31, 2008 in Massachusetts, EMSANT-W identified 103,059 women with probable SUD. EMSANT-W identified 4,116 women who were not identified by the widely used Clinical Classifications Software for Mental Health and Substance Abuse (CCS-MHSA) and did not capture 853 women identified by CCS-MHSA. Content and approach innovations in EMSANT-W address potential limitations of the Clinical Classifications Software, and create a methodologically sound, gender-tailored and feasible population-based tool for identifying women of reproductive age in need of further evaluation for SUD treatment. Rapid changes in health care service infrastructure, delivery systems and policies require tools such as the EMSANT-W that provide more precise identification methods for sub-populations and can serve as the foundation for analyses of treatment use and outcomes.

Endogenous opiates and behavior: 2013

This paper is the thirty-sixth consecutive installment of the annual review of research concerning the endogenous opioid system. It summarizes papers published during 2013 that studied the behavioral effects of molecular, pharmacological and genetic manipulation of opioid peptides, opioid receptors, opioid agonists and opioid antagonists. The particular topics that continue to be covered include the molecular-biochemical effects and neurochemical localization studies of endogenous opioids and their receptors related to behavior, and the roles of these opioid peptides and receptors in pain and analgesia; stress and social status; tolerance and dependence; learning and memory; eating and drinking; alcohol and drugs of abuse; sexual activity and hormones, pregnancy, development and endocrinology; mental illness and mood; seizures and neurologic disorders; electrical-related activity and neurophysiology; general activity and locomotion; gastrointestinal, renal and hepatic functions; cardiovascular responses; respiration and thermoregulation; and immunological responses.

Methadone overdose and cardiac arrhythmia potential: findings from a review of the evidence for an American Pain Society and College on Problems of Drug Dependence clinical practice guideline

The number of deaths associated with methadone use increased dramatically in parallel with marked increases in its use, particularly for treatment of chronic pain. To develop a clinical guideline on methadone prescribing to reduce potential harms, the American Pain Society commissioned a review of various aspects related to methadone safety. This article summarizes evidence related to unintentional overdose due to methadone and harms related to cardiac arrhythmia potential. We searched Ovid MEDLINE, the Cochrane Library, and PsycINFO databases through January 2014 for studies assessing harms associated with methadone use; we judged 70 studies to be relevant and to meet inclusion criteria. The majority of studies on overdose and cardiac arrhythmia risk are observational and provide weak evidence on which to base clinical guidelines. In patients prescribed methadone for treatment of opioid dependence, data suggest that mortality benefits related to reduction in illicit drug use outweigh harms. Despite epidemiologic data showing marked increases in the numbers of methadone-related deaths that have been primarily attributed to increased use of methadone for chronic pain, evidence on methadone and mortality risk in this population has been somewhat contradictory. There is some evidence that recent initiation of methadone, psychiatric admissions, and concomitant use of benzodiazepines are associated with a higher risk for overdose. Evidence on cardiac risks is primarily limited to case reports of torsades de pointes, primarily in patients on high doses of methadone, and to studies showing an association between methadone use and prolongation of QTc intervals. Research is needed to understand the effectiveness of dosing methods, electrocardiogram monitoring, and other risk mitigation strategies in patients prescribed methadone.

PERSPECTIVE

This systematic review synthesizes the evidence related to methadone use and risk for overdose and cardiac arrhythmia. Findings regarding the association between methadone use and QTc interval prolongation and risk factors for methadone-associated overdose suggest potential targets for risk mitigation strategies, though research is needed to determine the effectiveness of such strategies at reducing adverse outcomes.

Development and implementation of an opioid overdose prevention program within a preexisting substance use disorders treatment center

This case study of the development and implementation of an opioid overdose prevention program is based on an actual clinic's experience, but information about the clinic, including details of implementation and outcome measures, has been changed. Four experts reflect on the medical, administrative, peer-support, community, and evaluation aspects of this case. This discussion highlights challenges and important considerations in the creation of programs to address the ever-increasing risk for opioid overdose.
