Critical appraisal of interventional clinical trials assessing heated tobacco products: a systematic review

OBJECTIVE

To critically assess the methodological characteristics and quality of interventional clinical trials investigating the effects of heated tobacco products (HTPs).

DATA SOURCES

Web of Science (Core collection and MEDLINE), Scopus, MedRxiv, ClinicalTrials.gov and ICTRP trial databases and transnational HTP manufacturer online publication libraries were searched for clinical trials on HTPs published between January 2010 and April 2022.

STUDY SELECTION

Interventional clinical trials of any design, in which at least one group of adult participants used a currently marketed HTP, were selected by two reviewers with good or very good agreement.

DATA EXTRACTION

Data relating to trial characteristics and effects of intervention on primary outcomes were extracted using a predesigned form. Risk of bias was assessed using Cochrane's Risk of Bias tool v1.

DATA SYNTHESIS

40 trials were included, 29 of which were tobacco industry affiliated. Methodological characteristics, such as registration, design, setting, comparator interventions, participants, outcomes and analyses, varied between trials, though there were few significant differences between industry-affiliated and independent trials. Of the 40 trials, 33 were judged to be at high risk of bias and 6 at unclear risk of bias. Trial findings were not significantly associated with either affiliation or risk of bias.

CONCLUSIONS

The conduct and reporting of HTP interventional clinical trials were poor in many respects and limited to investigating effects of short-term exposure. These trials fall short of what is needed to determine whether HTPs are beneficial to public health, meaning they may not be a sound basis for tobacco control policy decisions.

Pharmacist-only supply of nicotine vaping products: proposing an alternative regulatory model for Australia

Regulation of nicotine vaping products (NVPs) is an ongoing challenge across the world. Australia currently has a globally unique NVP regulatory model that requires a medical prescription to purchase and use NVPs, with further restrictions in progress in response to evidence of widespread illicit NVP sales. Against this background, we examine the new measures and consider a modification of the model to pharmacist-only supply as an option for increasing access to NVPs for smoking cessation, while retaining health practitioner oversight of supply. We describe the strengths and challenges of implementing a pharmacist-only NVP supply option in Australia. Compared with the current prescription-only model, pharmacist-only supply could increase access to a lower exposure nicotine product in a highly regulated therapeutic context while addressing youth access and purchasing for non-therapeutic use, reduce demand for illicit products for smoking cessation purposes and avoid overburdening medical services with consultations to obtain NVP prescriptions. This approach can also accommodate current government goals such as eliminating NVP advertising, youth-focused branding and supply from grocery and convenience stores.

Vaping in a heavily regulated setting: cross-sectional survey of e-cigarette use, perceptions and social media exposure

BACKGROUND

Singapore has completely banned e-cigarettes and the government's cautious stance against vaping has been consistent. Despite this, vaping appears to have gained popularity in Singapore, especially among younger people. With the heavy marketing of vaping products on social media, it is possible that such marketing, due to its cross-border nature, is reaching younger Singaporeans and driving changes in vaping-related perceptions or behaviours. This study examines their exposure to vaping-related content on social media, and whether such exposure is associated with more positive perceptions of vaping or e-cigarette ever use.

METHODS

Analysis of cross-sectional survey data of 550 adult (age 21-40 years) Singaporeans recruited via convenience methods in May 2022, using descriptive statistics, bivariate analyses, and multiple linear and logistic regression models.

RESULTS

16.9% of participants reported they had ever used e-cigarettes. 18.5% of those who used social media recalled seeing vaping-related content on a social media platform in the past 6 months, mostly from influencers or friends, and on Instagram, Facebook, TikTok and/or YouTube. Reporting exposure to such content was not associated with e-cigarette ever use. It was associated with having a more positive overall perception of vaping (β=1.47; 95% CI: 0.17 to 2.78), although no significant difference was observed when examining only health-related perceptions.

CONCLUSION

Even in a heavily regulated environment such as Singapore's, people appear to be exposed to vaping-related content on social media platforms and this exposure is, in turn, associated with more positive perceptions of vaping, but not e-cigarette ever use.

Impact of waterpipe tobacco taxation on consumption, government revenue and premature deaths averted in Jordan, Lebanon and Palestine: a simulation study

INTRODUCTION

Despite the high prevalence of waterpipe tobacco smoking in the Eastern Mediterranean region, evidence supporting its fiscal measures is limited. We modelled the impact of waterpipe tobacco-specific excise taxes on consumption, government revenue and premature deaths averted in Jordan, Lebanon and Palestine.

METHODS

We developed a simulation model using country-specific and market share-specific price, consumption and price elasticity data from WHO, UN Comtrade and nationally representative surveys. We modelled increases to specific excise taxes to meet a 35.9% tax burden on 20 g of waterpipe tobacco in Lebanon and Jordan, in line with the global average, and to double government revenues from excise duties in Palestine, which has surpassed this average.

RESULTS

Specific excise tax was raised by $1.14 ($0.18-$1.32) in Jordan, $2.41 ($0.03-$2.44) in Lebanon (alongside removal of ad valorem taxes) and $2.39 ($1.72-$4.11) in Palestine per 20 g of waterpipe tobacco. Government revenue increased by $126.3 million in Jordan, $53.8 million in Lebanon and $162.4 million in Palestine while waterpipes smoked decreased by 32.4% in Jordan, 71.0% in Lebanon and 16.3% in Palestine. The corresponding numbers of premature deaths averted annually were approximately 162 000; 1 000 000; and 52 000.

DISCUSSION

Increases in waterpipe tobacco-specific excise taxes substantially reduce smoking and increase government revenue and averted premature deaths in Jordan, Lebanon and Palestine. This has positive implications for both public health and financing and should be considered a policy priority.

Effects of liquid nicotine concentration and flavour on the acceptability of electronic nicotine delivery systems (ENDS) among people who smoke participating in a randomised controlled trial to reduce cigarette consumption

BACKGROUND

Research is needed to understand the acceptability of electronic nicotine delivery systems (ENDS) as a smoking reduction aid. This study examines the acceptability of ENDS by liquid nicotine concentration and flavour among people who smoke using ENDS to reduce their smoking.

METHODS

People who smoke cigarettes but were naïve to ENDS participated in a double-blind randomised controlled trial to reduce conventional cigarette smoking. Participants were randomised to either a control cigarette substitute (CS) or one of three ENDS groups; 0 mg/mL, 8 mg/mL or 36 mg/mL nicotine concentration. ENDS flavour was chosen by the participant (tobacco or menthol). Participants reported their CS, ENDS and cigarettes per day (CPD) from the past 7 days at 1-month, 3-month and 6-month follow-up visits. Participants also reported side effects and measures of satisfaction, psychological reward, aversion and craving relief. Outcome variables were modelled using linear mixed effects by the following groups: liquid nicotine concentration, flavour and a flavour-nicotine concentration interaction.

RESULTS

Participants (n=520) were 41.2% male, 67.3% white, had a mean age of 46.2 years and smoked a mean of 18.6 CPD (SD=7.74) at baseline. All flavour and concentration groups decreased CPD from baseline to all follow-up visits with the 36 mg/mL experiencing the greatest reduction, compared with the 0 mg/mL and 8 mg/mL groups. All groups except the 36 mg/mL group decreased their product use over time. The use of menthol flavour was associated with fewer side effects at 3 months (p=0.02) and lesser aversion at 1 month (p=0.03) compared with tobacco-flavoured ENDS. The 36 mg/mL group experienced the greatest craving relief and greatest aversion compared with other groups.

CONCLUSIONS

Both nicotine concentration and flavour appear to have independent, as well as interactive, effects that influence ENDS acceptability among people who use cigarettes.

Contribution of proactive management of healthcare risks to the reduction of adverse events in a maternity hospital

BACKGROUND

The risks of the childbirth assistance process are still very high, both for mothers and babies. According to the WHO, birth-related asphyxia accounts for 23% of all 3.3 million annual neonatal deaths and an even larger number of survivors with disabilities. On the other hand, maternal mortality is still a global challenge, affecting 17 mothers per 100 000 births in the USA. This is associated with the use of outdated technologies and a lack of well-defined processes in monitoring labour and early recognition of maternal clinical deterioration.

METHOD

This study used Lean methodology to map the care flow for pregnant women in a Brazilian maternity hospital (Hospital Israelita Albert Einstein) in order to identify the risks within this process and a set of actions to minimise them. The work team consisted of 29 individuals, including local medical and nursing leaders, as well as healthcare professionals. The What-if tool was used to categorise the levels of risks, and the proportion of severe and catastrophic adverse events was evaluated before and after the implementation of changes.

RESULTS

After the implementation of the actions, 100% of the extreme risks (28 risks) and 8% of the high risks (4 risks) were eliminated. This led to a reduction in the interval between severe/catastrophic events from 126 to 284 days, even with an increase in the average monthly number of visits from 367 to 449. Consequently, the weighted value of events decreased from 7.91 to 3.29 per 1000 patients treated, resulting in an annual cost savings of R$693 646.80 (US$139 000.00).

DISCUSSION

The construction of a process based on Lean methodology was essential for mapping the involved risks and implementing a set of actions to minimise them. The participation of the healthcare team and leadership seemed to be important in choosing the measures to be adopted and their applicability. The results found can be attributed to both the established changes and the safety culture brought about by this constructive process.

The role of IQOS risk perceptions on cigarette smoking behaviours: results from a prospective pilot study

BACKGROUND

IQOS is a heated tobacco product marketed as an alternative to combustible cigarette smoking. Little is known about cigarette smokers' IQOS health risk perceptions and if these risk perceptions impact IQOS use and cigarette smoking behaviour.

METHODS

Adult, daily, non-treatment-seeking cigarette smokers (n=27), naïve to IQOS, were recruited from Philadelphia, Pennsylvania, USA. Participants were introduced to IQOS and then completed measures of risk perceptions. Participants were given an IQOS 2.4 holder, charger and HeatSticks, and asked to switch completely from cigarettes to IQOS for 14 days. The effects of risk perceptions on changes in IQOS use, cigarettes per day (CPD), the substitution of IQOS for cigarettes and motivation to quit smoking were evaluated.

RESULTS

Over the 14-day switch period, CPD significantly decreased (B=-0.18, 95% CI=-0.26 to -0.09, p<0.0001), IQOS use significantly increased (B=0.02, 95% CI=0.00 to 0.03, p=0.042), as did the percentage IQOS HeatSticks that replaced CPD (B=0.02, 95% CI=0.01 to 0.03, p=0.005). Participants who perceived IQOS as less risky than cigarettes used fewer IQOS HeatSticks per day. A lower percentage of IQOS HeatStick substitution for cigarettes was observed for participants with higher versus lower risk perceptions (B=-0.14, 95% CI=-0.28 to -0.01, p=0.042). Motivation to quit increased from a mean of 5.53 to 6.79 on the contemplation ladder from baseline to day 14 (B=1.26, 95% CI=0.54 to 1.97, p<0.001).

CONCLUSIONS

Smokers reduced their smoking rate and increased motivation to quit smoking while using IQOS. IQOS risk perceptions did not directly account for reductions in smoking, although they may contribute indirectly through increased IQOS use.

PMI-funded foundation for a smoke-free world: application of criteria to assess funding models that include financial support from the tobacco industry

Recent changes to the leadership and the terms of tobacco industry financing of the Foundation for a Smoke-Free World (FSFW) have called for a revisiting of a paper published in 2009 where we proposed criteria and other considerations to assess possible funding models for research that include financial support from the tobacco industry. This paper reviews and attempts to apply the elements laid out in 2009 to the current state of FSFW. After discussing each criterion and consideration we conclude that, at this point in time, conducting a thorough assessment using our 2009 paper is not possible because critical details related to FSFW governance, decision-making and process have not been announced. Nonetheless, we hope this paper will remind the tobacco control community that the 2009 criteria exist and highlight the information needed and questions that might be asked of FSFW to help form judgements about this new iteration of the foundation. We further hope this will put the FSFW on notice that they need to address each of these criteria and speak publicly about their plans regarding the specific issues raised in the 2009 paper.

Addressing Perinatal Opioid Use at a Local Health Department in Florida

PURPOSE

Perinatal substance use disorders (SUDs) remain an urgent public health concern in the United States and are associated with increased maternal and infant morbidity and mortality. Establishing holistic prenatal care among this population allows for engaging or re-engaging the pregnant population in appropriate medical care, including treatment for SUD.

DESCRIPTION

The Florida Department of Health in Citrus County (DOH-Citrus) noticed an increase in SUD among their pregnant population and developed a pilot program that incorporates Medication for Opioid Use Disorder (MOUD) and mental health services during routine prenatal care appointments.

ASSESSMENT

Since the launch of the pilot program, DOH-Citrus has provided prenatal programs with buprenorphine assistance to 23 members of the community.

CONCLUSION

A growing number of local health departments (LHDs) provide harm reduction supplies, overdose prevention education, and local resources for treatment and other life-saving services. In many communities, LHDs are typically the most accessible sources of public health information and health care services. By framing the pilot program as a prenatal care center that incorporates SUD treatment as the prescribed standard of care, DOH-Citrus has implemented a holistic model for treating SUD and reducing barriers while improving continuity of care. LHDs are uniquely positioned to implement harm reduction strategies that address perinatal SUDs, treatment, and recovery within maternal and child health populations. As a health department located in a state without expanded Medicaid and with high rates of uninsured people, this pilot program has the potential to be replicated in other states facing similar challenges.

Drug-related deaths at Australian music festivals

BACKGROUND

Illicit drug use is overrepresented in music festival attendees compared with the general population. Drug use often involves a wide range of substances with the potential to cause drug toxicity. Law enforcement-centred strategies intended to deter drug use and supply at these mass gatherings have been implemented throughout Australia. However, many have been criticised for their lack of effectiveness, with evidence suggesting that they can inadvertently increase the risk of drug harm. Drug deaths are often multifactorial, providing added challenges in the development of prevention strategies. This study aimed to determine the frequency of deaths involving alcohol and other drugs at music festivals in Australia and to identify potential risk factors that may inform future harm reduction strategies.

METHODS

A descriptive case series study was conducted using the National Coronial Information System (NCIS) to investigate drug-related deaths at music festivals throughout Australia between 1 July 2000 (Queensland from 1 January 2001) and 31 December 2019, using a list of keywords comprising music festival names and terms.

RESULTS

There were 64 deaths, of which most involved males (73.4%) aged in their mid-20s (range 15-50 years). Drug toxicity was the most common primary cause of death (46.9%) followed by external injuries (37.5%). The drug most commonly detected or reported as being used was MDMA (65.6%), followed by alcohol (46.9%) and cannabis (17.2%), with most cases reporting the use of two or more drugs (including alcohol) and 36% reporting a history of drug misuse in the coroner's findings. Most deaths were unintentional, with less than a fifth of cases (17.2%) involving intentional self-harm. Clinical intervention was involved in 64.1% of cases and most festivals occurred in inner city locations (59.4%).

CONCLUSIONS

The findings suggest that drug-related deaths at music festivals in Australia typically involve young people using multiple illicit substances in combination with alcohol. Most are unintentional and could potentially be prevented through the implementation of a range of harm reduction strategies, including mobile medical care, drug checking services, and increased consumer education and awareness.

Effects of flavour and modified risk claims on nicotine pouch perceptions and use intentions among young adults who use inhalable nicotine and tobacco products: a randomised controlled trial

BACKGROUND

Availability of flavours and potential modified risk tobacco product (MRTP) claims may influence young adults' (YAs') perceptions of and intentions to use nicotine pouches ('pouches').

METHODS

YAs aged 21-34 years (N=47, M age=24.5, SD=3.1) with past-month nicotine/tobacco use (10.6% cigarette-only, 51.1% e-cigarette-only, 38.3% dual use) and no intention to quit were randomised to self-administer four Zyn 3 mg nicotine pouches in a 4 (flavour; within-subjects: smooth, mint, menthol, citrus) × 2 (MRTP claim on packaging; between subjects: present or absent) mixed-factorial design. After self-administering each pouch, participants reported appeal, use intentions and perceived harm compared with cigarettes and e-cigarettes. Three mixed-factorial analysis of variances (ANOVAs) examined main and interactive effects of flavour and MRTP claim on appeal, use intentions and comparative harm perceptions.

RESULTS

Mint (M=55.9, SD=26.4), menthol (M=49.7, SD=26.8) and citrus (M=46.6, SD=24.8) flavours were significantly more appealing than smooth (M=37.6, SD=25.4; p<0.001). MRTP claim did not significantly affect product appeal (p=0.376). Use intentions were greater for mint (M=2.6, SD=1.3) and menthol (M=2.0, SD=1.1) flavours than smooth (M=1.8, SD=1.0; p=0.002). Flavour did not affect comparative harm perceptions (p values>0.418). MRTP claims increased use intention (p=0.032) and perceptions of pouches as less harmful than cigarettes (p=0.011), but did not affect perceived harm relative to e-cigarettes (p=0.142). Flavour × MRTP claim interactions were not significant.

CONCLUSIONS

Flavoured (vs smooth) pouches were more appealing to YAs. MRTP claims reduced perceived harm of pouches compared with cigarettes; however, intentions to switch were low. To protect YAs' health, regulatory restrictions could target flavours and MRTP claims.

Opportunities to improve opioid use disorder care for hospitalised patients with endocarditis

BACKGROUND

Driven by increased injection opioid use, rates of hospitalisation for infective endocarditis, an infection associated with injection drug use, are increasing. In the USA, 1 in 10 hospitalised patients for opioid use disorder-associated infective endocarditis (OUD-IE) die in the hospital and 1 in 20 have a patient-directed discharge. Emerging models of care reveal opportunities for healthcare systems to meet the complex care needs of these patients. We characterised promising practices of staff who care for these patients and identified areas for improvement.

METHODS

We conducted a qualitative study with 1-hour semistructured virtual interviews between October 2021 and March 2022. Participants included 26 healthcare staff who care for patients with OUD-IE at the Hospital of the University of Pennsylvania. We used thematic analysis of interviews guided by an abductive approach. Interviews were digitally recorded and transcribed and analysed using NVivo software.

RESULTS

Interviews were characterised by three major themes: (1) care rooted in interdisciplinary collaboration; (2) managing OUD and its sequelae in a setting not designed to treat OUD; and (3) clinician needs and barriers to change.

CONCLUSIONS

These findings highlight the facilitators of high-quality treatment for patients with OUD-IE, as well as the key areas for improvement. Findings add context to the complexity that both the healthcare staff and patients navigate during and following hospitalisation for OUD-IE. Needed changes include training staff to talk with patients about preparing for a return to drug use following hospitalisation, and changing discharge facilities' practices that hinder access for patients with OUD-IE.

They Will Never Forget How You Made Them Feel: Implementing Harm Reduction in the Perinatal Setting

Harm reduction is a framework built upon respect for people who use drugs. Pregnancy is a priceless window of opportunity for positive change, when parents are driven to improve their health and well-being for their future child, and harm reduction can provide direction for this motivation. Perinatal harm reduction can include goals of abstinence, decreased use, safer use, or a goal unrelated to substance use, such as obtaining housing or employment. We engage in harm reduction, not only by promoting beneficial practices, but by eliminating harmful ones. Despite the science, effective program models, and overwhelming agreement that substance use disorder is a health condition and not deviant behavior, harm reduction programs for pregnant and parenting people are rare, and punitive treatment is the norm. To achieve equitable treatment for people with perinatal substance use disorder and protect the parent-infant dyad, we must stop harmful practices, respect the autonomy of people who use drugs, and address substance use disorders while increasing access to the social determinants of health.

Factors Associated with Gaps in Naloxone Knowledge: Evidence from a 2022 Great Plains Survey

Background

The rising prevalence of fast-acting opioids in the United States suggests the increased need for non-first responder administration of naloxone. Effective administration of naloxone during an overdose requires that bystanders are familiar with, have access to, and know how to use naloxone.

Methods

Drawing on the 2022 Nebraska Annual Social Indicators survey, we analyzed naloxone familiarity, access, and competency to administer among a statewide, address-based sample of Nebraskan adults.

Results

There were significant gaps in naloxone knowledge in Nebraska. Although 75.6% of respondents were familiar with naloxone, only 18.6% knew how to access naloxone and 17.6% knew how to use naloxone. We find that more frequent religious service attendance is associated with lower odds of naloxone familiarity. Among those familiar with naloxone, a higher perception of community stigma towards opioids generally is associated with lower odds of naloxone access and competency. Higher perception of community stigma towards heroin, methamphetamines, and cocaine, however, is associated with higher odds of naloxone access. Finally, past overdose experience, lifetime illicit opioid use, being close to a person who uses opioids, and having access to illicit opioids was not significantly associated with naloxone familiarity, access, or competency among respondents in Nebraska's two largest cities, Omaha and Lincoln. Outside of these cities, past overdose experience and access to illicit opioids was associated with higher odds of naloxone access and competency, but lifetime opioid use and being close to a person who uses opioids had no effect.

Conclusions

Our findings highlight the continued need for education on naloxone with a specific focus on access and competency to further reduce opioid-related overdose deaths. Education campaigns targeted at places of worship or individuals close to people who use opioids may further serve those with a lower likelihood of naloxone familiarity and promote knowledge of naloxone among those with higher odds of encountering an overdose. Further work is needed to understand differences in the relationship between substance-specific perceived stigma and its association with naloxone access.

Menthol versus non-menthol flavouring and switching to e-cigarettes in black and Latinx adult menthol combustible cigarette smokers: secondary analyses from a randomised clinical trial

BACKGROUND

As the US Food and Drug Administration takes regulatory action on menthol cigarettes, debate continues about how restricting menthol e-liquids might impact adult menthol smokers in switching to e-cigarettes.

METHODS

Switching patterns and e-cigarette acceptability were assessed at week 6 among 64 black and Latinx menthol cigarette smokers who used JUUL menthol (n=39) or non-menthol e-cigarettes ((n=25), primarily mint or mango) as part of a randomised switching trial.

RESULTS

No clear evidence of effects was found between menthol versus non-menthol e-cigarettes on use or subjective effects/acceptability, effect sizes for all comparisons were small (effect size=0.0-0.2), and Bayes factor ranged from 0.10 to 0.15. Specifically, 82.1% of participants who used menthol-flavoured e-cigarettes fully or partially switched to e-cigarettes compared with 88.0% of participants who used a non-menthol (p=0.75). Further, both groups demonstrated substantial reductions in cigarettes per day (menthol e-cigarettes: -8.5±10.4 vs non-menthol e-cigarettes: -8.8±5.8, p=0.87), comparable grams of e-liquid consumed (menthol e-cigarettes: 9.2±9.8 g vs non-menthol e-cigarettes: 11.0±11.0 g, p=0.47), and positive subjective effects, including 'just right' throat hit (menthol e-cigarettes: 70.7% vs non-menthol e-cigarettes: 66.7%, p=0.93) and flavour liking (menthol e-cigarettes: 75.6% vs non-menthol e-cigarettes: 66.7%, p=0.32).

CONCLUSIONS

Both menthol and non-menthol e-cigarettes were associated with high rates of use and acceptability among menthol smokers. Findings require confirmation in a fully powered non-inferiority or equivalence study but provide preliminary evidence to inform regulatory action on menthol e-cigarettes that could slow youth initiation without impacting black and Latinx menthol cigarette smokers interested in switching to e-cigarettes.

Development and Validation of a Protective Behavioral Strategies Scale for Individuals who use Opioids: Preliminary Findings and Future Directions

Background

Protective Behavioral Strategies (PBS) are individually implemented harm reduction (HR) strategies to reduce the frequency or severity of risks associated with drug use. Existing scales measuring PBS for alcohol and cannabis suggest PBS are associated with reductions in associated problems. Despite many HR strategies related to opioid use, no PBS scale has been developed in the context of opioid use. To address this gap, this study aimed to test and validate a PBS scale for individuals using opioids (PBSO).

Methods

An online survey utilized a 32-item PBS scale for individuals endorsing recent opioid use, and measured opioid use frequency, HR service use, and experience of opioid overdose. PBSO items were rated on a Likert scale ranging from "never" (0) to "always" (6), and an exploratory factor analysis (EFA) examined factor structure.

Results

In the current sample (n=499; 32% female), EFA suggested a 3-factor structure among the 28 items retained, accounting for 51% of total variance. Factor 1 reflected health-service seeking, Factor 2 reflected individually-implemented and dose-reduction strategies, Factor 3 reflected social strategies, and Factor 4 reflected strategies related to injection drug use. Endorsement of PBSO items were slightly above "occasional" (3). PBSO use appeared positively related to past-month HR service utilization and negatively related to opioid use frequency.

Conclusions

Findings provide preliminary support for the PBSO scale as a valid and reliable measure. Further work is needed to test this scale in larger samples, and future work should explore the association between PBSO and relevant health outcomes, and whether factor scores differentially impact these outcomes.

Public opinions and attitudes toward a state monopoly: a study of the finnish gambling system

BACKGROUND

Gambling regulated through a state monopoly is often justified for reasons of public health, that is, that monopolies are a more effective means of reducing potential harm. This focus on harm prevention has increased in recent years, particularly as a result of pressures arising from the growth of online gambling and of legislation designed to promote competition. While prior works have examined the role of stakeholders in influencing policy decisions and in public discussions of the monopoly systems, attention has been focused on those with direct financial interests; the opinions of the public have largely been absent from these discussions. In 2017 Finland restructured its monopoly order to improve efficacy of addressing gambling related harms; this restructuring offers a valuable insight into public perceptions of and attitudes toward the suitability of the Finnish system to address gambling-related harm.

METHODS

This work uses Structural Equation Modelling and compares attitudes toward the Finnish system between 2015 (pre-restructuring) and 2019 (post-restructuring).

RESULTS

Overall public opinion of the Finnish system as being suitable for addressing gambling harms declined between 2015 and 2019, despite the restructuring. Several predictors of attitudes were identified, however, the majority had small effect sizes, while the model explained little variance.

CONCLUSION

This work concludes that existing approaches to examining public opinions of gambling regulation should be amended to include additional predictors. Furthermore, it is likely that context-specific predictors should be included in models, in order to reflect the socio-cultural history of the population being investigated. Such predictors should be determined in respect to the population of interest but, for example, could include items measuring trust in authority, political orientation, cultural acceptance of gambling, or religious affiliation.

Association of drug overdoses and user characteristics of Canada's national mobile/virtual overdose response hotline: the National Overdose Response Service (NORS)

BACKGROUND

Several novel overdose response technology interventions, also known as mobile overdose response services (MORS), have emerged as adjunct measures to reduce the harms associated with the drug poisoning epidemic. This retrospective observational study aims to identify the characteristics and outcomes of individuals utilizing one such service, the National Overdose Response Service (NORS).

METHODS

A retrospective analysis was conducted using NORS call logs from December 2020 to April 2023 imputed by operators. A variety of variables were examined including demographics, substance use and route, location, and call outcomes. Odds ratios and 95% confidence intervals were calculated around variables of interest to test the association between key indicators and drug poisonings.

RESULTS

Of the 6528 completed calls on the line, 3994 (61.2%) were for supervised drug consumption, 1703 (26.1%) were for mental health support, 354 (5.42%) were for harm reduction education or resources, and 477 (7.31%) were for other purposes. Overall, there were 77 (1.18%) overdose events requiring a physical/ in-person intervention. Of the total calls, 3235 (49.5%) were from women, and 1070 (16.3%) were from people who identified as gender diverse. Calls mostly originated from urban locations (n = 5796, 88.7%) and the province of Ontario (n = 4137, 63.3%). Odds ratios indicate that using opioids (OR 6.72, CI 95% 3.69-13.52), opioids in combination with methamphetamine (OR 9.70, CI 95% 3.24-23.06), multiple consumption routes (OR 6.54, CI 95% 2.46-14.37), and calls occurring in British Columbia (B.C) (OR 3.55, CI 95% 1.46-7.33) had a significantly higher likelihood of a drug poisoning. No deaths were recorded and only 3 false callouts had occurred. The overall drug poisoning event incidence to phone calls was 1.2%.

CONCLUSION

NORS presents a complimentary opportunity to access harm reduction services for individuals that prefer to use alone or face barriers to accessing in-person supervised consumption services especially gender minorities with high-risk use patterns.

Patient aggression towards receptionists in general practice: a systematic review

OBJECTIVE

General practice receptionists provide an essential function in the healthcare system but routinely encounter acts of incivility and aggression from patients, including hostility, abuse and violence. This study was conducted to summarise what is known about patient-initiated aggression towards general practice receptionists, including impacts on reception staff and existing mitigation strategies.

DESIGN

Systematic review with convergent integrated synthesis.

ELIGIBILITY CRITERIA

Studies published at any time in English that examine patient aggression experiences of reception staff in primary care settings.

INFORMATION SOURCES

Searches of five major databases were performed (CINAHL Complete, Scopus, PubMed, Healthcare Administration Database and Google Scholar) to August 2022.

RESULTS

Twenty studies of various designs were included, ranging from the late 1970s to 2022 and originating from five OECD countries. Twelve were assessed as high quality using a validated checklist. Reviewed articles represented 4107 participants; 21.5% were general practice receptionists. All studies reported that displays of aggression towards receptionists by patients were a frequent and routine occurrence in general practice, particularly verbal abuse such as shouting, cursing, accusations of malicious behaviour and use of racist, ablest and sexist insults. Although infrequent, physical violence was widely reported. Inefficient appointment scheduling systems, delayed access to doctors and prescription denial appeared common precipitators. Receptionists adapted their behaviour and demeanour to placate and please patients to avoid escalation of patient frustrations at the cost of their own well-being and clinic productivity. Training in patient aggression management increased receptionist confidence and appeared to decrease negative sequalae. Coordinated support for general practice reception staff who had experienced patient aggression was generally lacking, with a small proportion receiving professional counselling.

CONCLUSIONS

Patient aggression towards reception staff is a serious workplace safety concern for general practices and negatively affects healthcare sector function more broadly. Receptionists in general practice deserve evidence-based measures to improve their working conditions and well-being for their own benefit and that of the community.

MRTP claim authorisation and General Snus sales in the USA: evidence from a difference-in-differences model

BACKGROUND

The 2009 Tobacco Control Act granted the US Food and Drug Administration (FDA) regulatory authority over tobacco products, including the ability to authorise modified-risk tobacco product (MRTP) claims. In October 2019, the FDA authorised the first-ever MRTP claim for General Snus, which allowed the product to be marketed as reduced risk (relative to cigarettes). MRTP authorisation may increase otherwise low rates of snus use in the USA (<0.5% for children and adults).

METHODS

Using 2017-2021 Nielsen sales data from 19 US states, we conducted a difference-in-differences analysis to determine whether logged unit sales of General Snus were affected by the MRTP authorisation, compared with (1) sales of other snus brands and (2) sales of non-snus smokeless products; we also examined (3) if sales of non-General Snus brands were affected by General Snus's MRTP authorisation, compared with sales of non-snus smokeless tobacco products.

RESULTS

Although sales declined in absolute terms, sales of General Snus relative to other snus brands were unchanged after MRTP authorisation (-9.0%, 95% CI -19.6% to 1.60%, p=0.098). However, compared with non-snus smokeless brand sales, sales of General Snus (+14.7%, 95% CI 5.23% to 24.2%, p=0.002) rose after MRTP authorisation. Compared with non-snus smokeless products, sales of non-General Snus brands also rose after MRTP authorisation (+23.7%, 95% CI 9.5% to 38.0%, p=0.001).

CONCLUSIONS

Although only General Snus received MRTP authorisation, this designation appears to have slowed declines for the entire snus category. This suggests consumers may make determinations regarding product risk to a product class rather than individual products.

Predicting the long-term effects of electronic cigarette use on population health: a systematic review of modelling studies

OBJECTIVE

To systematically review and synthesise the findings of modelling studies on the population impacts of e-cigarette use and to identify potential gaps requiring future investigation.

DATA SOURCE AND STUDY SELECTION

Four databases were searched for modelling studies of e-cigarette use on population health published between 2010 and 2023. A total of 32 studies were included.

DATA EXTRACTION

Data on study characteristics, model attributes and estimates of population impacts including health outcomes and smoking prevalence were extracted from each article. The findings were synthesised narratively.

DATA SYNTHESIS

The introduction of e-cigarettes was predicted to lead to decreased smoking-related mortality, increased quality-adjusted life-years and reduced health system costs in 29 studies. Seventeen studies predicted a lower prevalence of cigarette smoking. Models that predicted negative population impacts assumed very high e-cigarette initiation rates among non-smokers and that e-cigarette use would discourage smoking cessation by a large margin. The majority of the studies were based on US population data and few studies included factors other than smoking status, such as jurisdictional tobacco control policies or social influence.

CONCLUSIONS

A population increase in e-cigarette use may result in lower smoking prevalence and reduced burden of disease in the long run, especially if their use can be restricted to assisting smoking cessation. Given the assumption-dependent nature of modelling outcomes, future modelling studies should consider incorporating different policy options in their projection exercises, using shorter time horizons and expanding their modelling to low-income and middle-income countries where smoking rates remain relatively high.

Preliminary effectiveness of online opioid overdose and naloxone administration training and impact of naloxone possession on opioid use

BACKGROUND

Despite the demonstrated value of opioid overdose education and naloxone distribution (OEND) programs, uptake and utilization remains low. Accessibility to OEND is limited and traditional programs may not reach many high-risk individuals. This study evaluated the effectiveness of online opioid overdose and naloxone administration education and the impact of naloxone possession.

METHODS

Individuals with self-reported illicit use of opioids were recruited via Craigslist advertisements and completed all assessments and education online via REDCap. Participants watched a 20-minute video outlining signs of opioid overdose and how to administer naloxone. They were then randomized to either receive a naloxone kit or be given instructions on where to obtain a kit. Effectiveness of training was measured with pre- and post-training knowledge questionnaires. Naloxone kit possession, overdoses, opioid use frequency, and treatment interest were self-reported on monthly follow-up assessments.

RESULTS

Mean knowledge scores significantly increased from 6.82/9.00 to 8.22 after training (t(194)=6.85, p <0.001, 95% CI[1.00, 1.81], Cohen's d=0.85). Difference in naloxone possession between randomized groups was significant with a large effect size (p <0.001, diff=0.60, 95% CI[0.47, 0.73]). A bidirectional relationship was found between naloxone possession and frequency of opioid use. Overdoses and treatment interest were similar across possession status.

CONCLUSIONS

Overdose education is effective in online video format. Disparity in naloxone possession across groups indicates barriers to obtaining naloxone from pharmacies. Naloxone possession did not influence risky opioid use or treatment interest and its impact on frequency of use warrants further investigation.

Integrating Harm Reduction into Medical Care: Lessons from Three Models

BACKGROUND

Substance use disorders (SUDs) are at a national high, with significant morbidity and mortality. Harm reduction, a public-health strategy aimed at reducing the negative consequences of a risky behavior without necessarily eliminating the behavior, represents a useful approach to engage patients with SUDs in care. The objective of this article is to describe how 3 medical practices operationalized harm reduction as a framework toward patient care and identify the common practices undertaken across these settings to integrate harm reduction and medical care.

METHODS

We conducted a qualitative study using in-depth, semistructured interviews with 20 staff and providers at 3 integrated harm reduction and medical care sites across New York State from March to June 2021. Interview questions focused on how harm reduction approaches were implemented, how harm reduction philosophies were demonstrated in practice, and barriers to adoption.

RESULTS

The interviews resulted in 8 main themes of integrated harm reduction medical care: 1) role of provider as both learner and informer; 2) pragmatic measures of success; 3) collaborative and interdisciplinary care teams; 4) developing a stigma-free culture; 5) creating a comfortable and welcoming physical space; 6) low-threshold care with flexible scheduling; and; 7) reaching beyond the clinic to disseminate harm reduction orientation; and 8) creating robust referral networks to enhance transitions of care. These themes existed at the patient-provider level (#1 to 3), the organizational level (#4 to 6), and the level extending beyond the clinic (#7 to 8).

CONCLUSIONS

All 3 sites followed 8 common themes in delivering harm reduction-informed care, most of which are consistent with the broader movement toward patient-centered care. These practices demonstrate how medical providers may overcome some of the barriers imposed by the medical model and successfully integrate harm reduction as an orienting framework toward care delivery.

Older age is associated with greater misperception of the relative health risk of e-cigarettes and cigarettes among US adults who smoke

INTRODUCTION

The prevalence of cigarette smoking among adults aged ≥55 has remained stagnant over the past decade. National data modelling suggests no reduction in cigarette smoking prevalence attributable to e-cigarette use in the USA among people aged ≥45. Misperceptions about the absolute risks (ie, cigarettes are not harmful) and relative risks (ie, e-cigarettes are more harmful than cigarettes) of tobacco products may contribute to sustained smoking prevalence and hesitancy to switch from cigarettes to e-cigarettes among older adults.

METHODS

Participants reported cigarette use (n=8072) at Wave 5 (2018-2019) of the Population Assessment of Tobacco and Health Study. Weighted multivariable logistic regressions included six age categories (independent variable) and cigarette and e-cigarette risk perceptions (outcomes). Additional models assessed the associations between dichotomous age (≥55 vs 18-54), risk perceptions and an interaction term (independent variables) with past 12-month quit attempts and past-month e-cigarette use (outcomes).

RESULTS

Adults aged ≥65 were less likely than adults aged 18-24 to rate cigarettes as very/extremely harmful (p<0.05). Odds of rating e-cigarettes as more harmful than cigarettes among adults aged 55-64 and ≥65 were 1.71 (p<0.001) and 1.43 (p=0.024) greater than for adults aged 18-24. This misperception was negatively associated with past-month e-cigarette use and was stronger among adults aged ≥55 (p<0.001) than adults aged <55 (p<0.001).

DISCUSSION

Adults aged ≥55 are more likely to have misperceptions about the absolute and relative risks of tobacco products, which may contribute to continued smoking. Health communications targeting this age group could modify beliefs about the perceived harms of tobacco products.

Requirements for implementing a 'just culture' within healthcare organisations: an integrative review

PURPOSE

To identify requirements for implementing a 'just culture' within healthcare organisations.

METHODS

Using Whittemore and Knafl's methodology for integrative reviews, we searched PubMed, PsychInfo, Cumulative Index of Nursing and Allied Health Literature, ScienceDirect, Cochrane Library and ProQuest Dissertations and Theses. Publications were considered eligible when reporting requirements for implementing a 'just culture' within healthcare organisations.

RESULTS

After screening for inclusion and exclusion criteria, 16 publications were included in the final review. Four main themes were identified: leadership commitment, education and training, accountability and open communication.

CONCLUSION

The themes identified in this integrative review provide some insight into the requirements for implementing a 'just culture' within healthcare organisations. To date, most of the published literature on 'just culture' is theoretical in nature. Additional efforts are needed to conduct research to explore further what requirements must be addressed in order to successfully implement a 'just culture' which is needed to promote and sustain a culture of safety.

IQOS print magazine advertising characteristics and reach before and after FDA authorisation as a modified risk tobacco product

INTRODUCTION

IQOS is a heated tobacco product that was authorised as a modified risk tobacco product (MRTP) in July 2020. While it was removed from the US market in 2021 for legal reasons, as the first tobacco product to receive an 'exposure modification' MRTP order, surveillance of IQOS marketing is needed to inform regulation and policy for future MRTPs. The purpose of this study is to expand the current research on IQOS advertising in the USA by examining content and readership characteristics of IQOS ads in print magazines before and after US Food and Drug Administration MRTP authorisation.

METHODS

We merged content analysis data with Kantar Media data on magazine placement and expenditures. Magazine readership data were obtained from MRI-Simmons. We compared data from pre-MRTP authorisation with data post-MRTP authorisation. This study was conducted in 2021.

RESULTS

There was one unique ad and there were 13 observations pre-MRTP, and eight unique ads and 132 observations post-MRTP. Compared with pre-MRTP ads, more post-MRTP ads featured Marlboro HeatSticks, including Amber HeatSticks, and featured people. All ads contained a warning label-most warning labels were cigarette specific. IQOS ads were featured in magazines that are especially popular among women.

CONCLUSIONS

After receiving MRTP authorisation, IQOS increased ad expenditures in print magazines with a readership comprised of primarily women. If IQOS returns to the US market, it will be important for tobacco control to monitor their advertisement content, placement, and expenditures.

Industry marketing of tobacco products on social media: case study of Philip Morris International's IQOS

SIGNIFICANCE

Newer tobacco products might be particularly likely to use social media as they emerge in the global market. Little is known about the official use of social media in marketing heated tobacco products (HTPs). This study examined Philip Morris International's (PMI) social media marketing globally of its leading HTP, IQOS.

METHODS

PMI IQOS country-specific official websites were accessed (N=59) in May to September 2022 and social media accounts listed were recorded. Accounts were then coded for their number of posts in the past month and year and for their number of subscribers. Posts on online accounts with at least one past-month post were categorised to describe the post's function: instructional, general advertising, price promotions or event promotions.

RESULTS

Of the 59 country websites, 45 (76.3%) listed at least one social media account; of these, an average of 2.5 accounts (SD=0.8) were listed. Across websites, 111 accounts were identified: 42 Facebook, 23 YouTube, 21 Twitter, 19 Instagram, 2 Telegram, 1 LinkedIn, 1 KakaoTalk, 1 VK and 1 LINE. Across YouTube, Twitter and Instagram, accounts made 2550 past-year posts and had ~490 961 subscribers. Of the 165 past-month posts, 101 (60.1%) functioned as general advertising, 30 (17.9%) instructional, 29 (17.3%) event promotions and 8 (4.8%) price promotions.

CONCLUSION

Social media posts were used to engage consumers with advertising, event promotions, product use instructions and price promotions. The study provides evidence of the company-sponsored official marketing of an HTP via social media globally, underscoring the need for monitoring and tobacco control regulatory efforts in the digital arena.

Prescribe, Review, Now!: an assessment of adequate PRN analgesia and associated laxative prescribing using Hospital Electronic Prescribing and Medicines Administration (HEPMA)

INTRODUCTION

On HEPMA there is no way to notify a prescriber if patients are regularly accessing PRN (as-required) analgesia. We aimed to assess how well PRN analgesia use is identified, the WHO analgesic ladder and whether laxatives were prescribed with opioid analgesia.

METHODS

3 data collection cycles were carried out for all medical inpatients between February-April 2022. Medication was reviewed to determine: 1) PRN analgesia prescribed? 2) Is the patient accessing it >3 times in 24hours? 3) Con-current laxatives prescribed. Between each cycle, an intervention was implemented. Intervention 1: Posters were placed on each ward and circulated electronically as a cue to a review and change analgesia "Prescribe.

REVIEW

Now!" Intervention 2: A presentation on data, the WHO analgesic ladder and laxative prescribing was created, and circulated.

RESULTS

See Figure 1 - Comparison of prescribing per cycle. Cycle 1 - 167 inpatients surveyed, 58%female, 42%male, mean age 78(±13.4). Cycle 2 - 159 inpatients,65% female, 35% male, mean age of 77 (±15.7). Cycle 3 - 157 inpatients, 62% female, 38% male, mean age 78 (±15.7). Adequate prescriptions on HEPMA improved by a total of 31% (p<0.005), over 3 cycles and 2 interventions.

CONCLUSIONS

After each intervention there was a significant statistical improvement in prescribing analgesia and laxatives. However, there is still room for further improvement, especially in ensuring adequate laxative cover is prescribed for all patients either >65 years old, or those on opioid-based analgesia. Visual reminders on wards of regularly checking PRN medication showed to be an effective intervention.

Impact of smoking intensity and device cleaning on IQOS emissions: comparison with an array of cigarettes

SIGNIFICANCE

IQOS is a heated tobacco product that has been widely advertised by Philip Morris International (PMI) as a reduced-exposure product compared with cigarettes. Reduced exposure results from reduced emission of toxicants which could be influenced by product constituents and user behaviour. This study aims to assess the influence of user behaviour, including device cleaning and puffing parameters, on toxicant emissions from IQOS.

METHODS

IQOS aerosols were generated by a smoking machine using the combination of two cleaning protocols (after 1 stick vs 20 sticks) and five puffing regimes (including standard cigarette puffing regimes and IQOS-tailored regimes). The generated aerosols were analysed by targeted methods for phenol and carbonyl quantification, and by chemical screening for the identification of unknown compounds.

RESULTS

Puffing parameters significantly affected phenol and carbonyl emissions while device cleaning had no effect. Harsher puffing conditions like more, longer, and larger puffs yielded higher levels for most toxicant emissions. Comparing the obtained data with data reported by PMI on 50 cigarette brands smoked under different puffing regimes showed various trends for phenol and carbonyl emissions, with IQOS emissions sometimes higher than cigarettes. Also, the chemical screening resulted in the tentative identification of ~100 compounds in the IQOS aerosols (most of limited toxicity data).

CONCLUSION

This study showed that puffing parameters, but not device cleaning, have significant effects on carbonyl, phenol and other emissions. Data analysis highlighted the importance of comparing IQOS emissions with an array of commercial cigarettes tested under different puffing regimes before accepting reduced exposure claims.

Day-to-day impact of COVID-19 and other factors associated with risk of nonfatal overdose among people who use unregulated drugs in five cities in the United States and Canada

BACKGROUND

The COVID-19 pandemic has compounded the longstanding drug poisoning crisis in Canada and the United States (US). Research is needed to understand the contributions of COVID-19 and subsequent infection control measures. We sought to estimate the prevalence of and factors associated with nonfatal overdose among participants in nine prospective cohorts of people who use unregulated drugs (PWUD) in Canada and the US.

METHODS

Data were derived from nine cohorts of PWUD in urban centres in Canada (Vancouver, BC) and the US (Baltimore, MD; Miami, FL; Chicago, IL; Los Angeles, CA) between May, 2020 and April, 2021. Multivariable logistic regression was used to identify factors associated with nonfatal overdose among participants who used unregulated drugs in the past month.

RESULTS

Among 885 participants (including 253 females), 41 (4.6 %) experienced a non-fatal overdose in the past month, and 453 (51.2 %) reported being highly impacted day-to-day by the pandemic. In multivariable analyses, people who experienced a non-fatal overdose were more likely to be female (Adjusted Odds Ratio [AOR]=2.18;95 % Confidence Interval [CI]=1.10-4.30); unstably housed/homeless (AOR=2.16;95 % CI=1.11-4.26); engaged in medications for opioid use disorder (AOR=2.45;95 % CI=1.19-4.97); and highly impacted day-to-day (AOR=2.42;95 % CI=1.22-5.10).

CONCLUSION

Our findings may reflect characteristics of participants who experienced a compounding of vulnerabilities during the pandemic and thus are vulnerable to overdose, including women, those unstably housed/homeless, and those who perceived their daily lives were highly impacted by the pandemic. Multi-level interventions are needed to remediate the vulnerabilities and address the main driver of poisoning crisis.

Assessing toxicant emissions from e-liquids with DIY additives used in response to a potential flavour ban in e-cigarettes

SIGNIFICANCE

Electronic cigarettes (e-cigarettes) aerosolise liquids that contain nicotine, propylene glycol, glycerol and appealing flavours. In the USA, regulations have limited the availability of flavoured e-cigarettes in pod-based systems, and further tightening is expected. In response, some e-cigarette users may attempt to make their e-liquids (do-it-yourself, DIY). This study examined toxicant emissions from several aerosolised DIY e-liquids.

METHODS

DIY additives were identified by reviewing users' responses to a hypothetical flavour ban, e-cigarette internet forums and DIY mixing internet websites. They include essential oils, cannabidiol, sucralose and ethyl maltol. E-liquids with varying concentrations and combinations of additives and tobacco and menthol flavours were prepared and were used to assess reactive oxygen species (ROS), carbonyl and phenol emissions in machine-generated aerosols.

RESULTS

Data showed that adding DIY additives to unflavoured, menthol-flavoured or tobacco-flavoured e-liquids increases toxicant emissions to levels comparable with those from commercial flavoured e-liquids. Varying additive concentrations in e-liquids did not have a consistently significant effect on the tested emissions, yet increasing power yielded significantly higher ROS, carbonyl and phenol emissions for the same additive concentration. Adding nicotine to DIY e-liquids with sucralose yielded increase in some emissions and decrease in others, with freebase nicotine-containing e-liquid giving higher ROS emissions than that with nicotine salt.

CONCLUSION

This study showed that DIY additives can impact aerosol toxicant emissions from e-cigarettes and should be considered by policymakers when restricting commercially available flavoured e-liquids.

'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.

Integrating anti-violence efforts into sexual and reproductive health: reproductive coercion as a case example

Integration of anti-oppression approaches into clinical practice, including sexual and reproductive health, is needed. Reproductive coercion is a common form of violence that directly impacts sexual and reproductive health. Person-centered harm reduction strategies for reproductive coercion can be integrated readily into routine care utilizing clinicians' existing skill set. Interventions for reproductive coercion may serve as a proof of concept for the incorporation of anti-violence and healing justice efforts within medical care.

Simulating the impact of Addiction Consult Services in the context of drug supply contamination, hospitalizations, and drug-related mortality

BACKGROUND

Illicitly manufactured fentanyl (IMF) is increasing in international drug supply chains, and IMF-related opioid overdose deaths are rising in North America. Hospitalizations among patients with opioid use disorder (OUD) are also rising; and, hospitalized patients are at increased risk of overdose and death following hospital discharge. Hospitalization is a key opportunity to engage patients with OUD. Addiction consult services (ACS) can provide effective treatment for patients hospitalized with OUD. This study aims to estimate the effect of increasing IMF contamination on drug-related death among patients hospitalized with OUD, and simulate the role of ACS expansion to mitigate these effects.

METHODS

We used a Markov model to mirror care systems for adult patients hospitalized with OUD in Oregon, from the time of hospital admission through 12-months post-discharge, and simulated patients through modeled care systems to evaluate the expansion of Addiction Consult Services in the context of increasing IMF in the drug supply.

RESULTS

In a simulated cohort of 10,000 patients, we estimate that 537 patients would die from drug-related causes within 12-months of hospital discharge. In the context of increased IMF in the drug supply, this estimate increased to 913. ACS referral at baseline was 4%; increasing ACS referral to accommodate 10%, 50%, or 100% of hospitalized OUD patients in the state reduces drug-related deaths to 904, 849, and 780, respectively. The number needed to treat for ACS to avoid one drug-related death in the context of increased IMF was 73.

CONCLUSIONS

Hospitals should expand interventions to help reduce IMF-related opioid overdoses, including through implementation of ACS. In the context of rising IMF-related deaths, ACS expansion could help connect patients to treatment, offer harm reduction interventions, or both, which can help reduce the risk of opioid-related death.

Medical Student Screening for Naloxone Eligibility in the Emergency Department: A Value-Added Role to Fight the Opioid Epidemic

INTRODUCTION

Opioid overdose education and naloxone distribution (OEND) for use by laypersons are safe and effective at preventing deaths from opioid overdose, but emergency department (ED) implementation is challenging. Curricula addressing OEND could enable students to serve in value-added roles on the clinical team, overcome challenges of naloxone distribution, and improve patient care.

METHODS

We created a 1-hour didactic session on opioid use disorder and OEND for first-year medical students in the emergency medicine elective. During two clinical shifts, students used this knowledge to perform screenings to identify patients at high risk of overdose. If a patient screened positive, students performed patient education and then notified the physician, who ordered a naloxone kit.

RESULTS

Thirty students received the didactic and conducted screening shifts. Of 147 patients screened, 40% (n = 59) were positive for naloxone eligibility, 21% (n = 31) reported that someone close to them used opioids, 18% (n = 26) had witnessed an opioid overdose, 12% (n = 17) had previously overdosed themselves, and 12% (n = 18) previously knew what naloxone was. Fifty-nine naloxone kits were distributed over the 3-month pilot versus 13 naloxone prescriptions for patients discharged from the ED the prior year.

DISCUSSION

Through didactic training and structured patient engagement, medical students gained knowledge of and hands-on experience with addiction medicine, discussed sensitive topics with patients, and identified a high volume of patients eligible to receive naloxone. Medical student screening for OEND in ED patients is feasible and adds significant value to the clinical team.

Integrated Psychosocial Group Treatment: A Randomized Pilot Trial of a Harm Reduction and Preventive Approach for Patients with Chronic Pain at Risk of Opioid Misuse

OBJECTIVE

To examine the benefits of an integrated psychosocial group treatment (IPGT) model for patients with chronic pain at risk of opioid misuse.

DESIGN

This study was a small-scale, single-blinded, two-group randomized controlled trial.

SETTING

Outpatient.

SUBJECTS

Adults with chronic pain of >3 months' duration who were currently prescribed opioid medication and were at risk of opioid misuse.

METHODS

Patients with chronic pain who were at risk of opioid misuse (n = 30) were randomly assigned to IPGT or treatment as usual. IPGT consists of six group sessions of psychoeducation, motivational interviewing, cognitive behavioral therapy, mindfulness, and peer support. Participants were assessed at baseline, first follow-up at 6 weeks, and a posttreatment follow-up at 9 weeks. Outcomes included feasibility, acceptability, and preliminary efficacy. Data were analyzed with descriptive and multivariate analyses.

RESULTS

All intervention components were delivered to 87% of the participants, and IPGT recipients reported a high level of satisfaction. Results of the multivariate analyses demonstrated nonsignificant improvements in pain severity (β = 0.22, 95% CI: -0.24 to 0.66, P = 0.35). However, we observed significant treatment × time interactions on pain interference (β = 3.32, 95% confidence interval [CI]: 0.01 to 6.65, P = 0.05) and pain catastrophizing (β = 2.74, 95% CI: 0.49 to 4.99, P = 0.02). Lastly, we detected no significant differences in opioid misuse (adjusted odds ratio = 0.69, 95% CI: -0.26 to 1.64, P = 0.16).

CONCLUSION

This study provides support for the IPGT intervention being acceptable and feasible for delivery in patients with chronic pain at risk of opioid misuse. Efficacy was achieved in pain interference and pain catastrophizing.

Cannabis Significantly Reduces the Use of Prescription Opioids and Improves Quality of Life in Authorized Patients: Results of a Large Prospective Study

OBJECTIVES

This article presents findings from a large prospective examination of Canadian medical cannabis patients, with a focus on the impacts of cannabis on prescription opioid use and quality of life over a 6-month period.

METHODS

The Tilray Observational Patient Study took place at 21 medical clinics throughout Canada. This analysis includes 1,145 patients who had at least one postbaseline visit, with follow-up at 1, 3, and 6 months. Instruments included a comprehensive cannabis use inventory, the World Health Organization Quality of Life Short Form (WHOQOL-BREF), and a detailed prescription drug questionnaire.

RESULTS

Participants were 57.6% female, with a median age of 52 years. Baseline opioid use was reported by 28% of participants, dropping to 11% at 6 months. Daily opioid use went from 152 mg morphine milligram equivalent (MME) at baseline to 32.2 mg MME at 6 months, a 78% reduction in mean opioid dosage. Similar reductions were also seen in the other four primary prescription drug classes identified by participants, and statistically significant improvements were reported in all four domains of the WHOQOL-BREF.

CONCLUSIONS

This study provides an individual-level perspective of cannabis substitution for opioids and other prescription drugs, as well as associated improvement in quality of life over 6 months. The high rate of cannabis use for chronic pain and the subsequent reductions in opioid use suggest that cannabis may play a harm reduction role in the opioid overdose crisis, potentially improving the quality of life of patients and overall public health.

Delivering harm reduction to the community and frontline medical practitioners through the South Australian Drug Early Warning System (SADEWS)

Australia does not have a formal drug early warning system. A coordinated program of fixed or event-based drug-checking is expensive and provides harm reduction information to atargeted user group. The South Australian Drug Early Warning System (SADEWS) is an informal inter-agency collaboration which rapidly and confidentially exchanges contemporary,evidence-based information about drug seizures, usage trends and clinical outcomes associated with drug use in South Australia. Information is sourced from policing, forensic analysis,waste-water analysis, medical research, clinical data and directly from people using drugs. SADEWS exchanges information relating to new drug emergences and clusters of adverseoutcomes following drug use, amongst members via secure digital platforms. The diverse but complimentary expertise of members allows a comprehensive assessment of changes tothe baseline risk associated with drug use and, where a potential community harm is identified, enables the timely delivery of warnings through formal mechanisms existing withinmember agencies. It is expected that these warnings contribute to significantly reduced medical consequences associated with community drug use through decreased drug overdosefatalities and hospital presentations rates, contributing to reduced healthcare costs. Importantly, this drug early warning system is politically risk-free, is achieved simply and without external funding or significant administrative overheads.

Risk factors for loss to follow-up of persons who inject drugs enrolled at syringe services programs in Kentucky

BACKGROUND

Syringe services programs (SSP) are an effective strategy to reduce blood-borne infections of human immunodeficiency virus (HIV) and hepatitis C virus (HCV) in persons who inject drugs (PWID). The objectives of this study were to determine the frequency and risk factors for loss to follow-up (LTFU) in PWID enrolled at SSPs in Kentucky.

METHODS

A retrospective cohort study was conducted which included data of PWID enrolled at 32 SSP. Demographics, use of drugs, HIV testing, HCV testing, and medical services were analyzed. A generalized linear model (GLM), family binomial was used to determine risk factors for LTFU.

RESULTS

The analysis included 5742 PWID. LTFU by year of enrollment was 287/770 (37.3%) in 2017, 796/1874 (42.5%) in 2018, and 1479/3,098 (47.7%) in 2019. LTFU was significantly associated with distance to SSP from home of more than five miles (RR 1.25; 95%CI 1.09-1.43; p = 0.002) and SSPs housed in rural counties (RR 1.22; 95%CI 1.06-1.40; p = 0.004), adjusted by age, sex, and race. The use of buprenorphine was associated with less risk of LTFU (RR 0.79, p = 0.034).

CONCLUSION

The distance to an SSP from home and SSPs in rural counties were identified as risk factors for LTFU. Initiatives that bring health services closer to PWID homes and offer opioid use disorder treatment may improve repeated participation in SSPs.

[Public policies for people who use drugs: Strategies for the elimination of stigma and the promotion of human rights]

This paper aims to provide theoretically informed practical proposals for the improvement of current drug policies, which are based on a biological model of disease and the criminalization of people who use drugs. First, we present alternatives to a biologically-oriented scientific conception centered around neuroscientific postulates, which support the idea that the etiology of addiction materializes in the brain, in favor of models based on the social sciences where context plays a relevant role in the description and management approaches regarding different uses of psychoactive substances. Second, epistemological models and proposals are offered from a practical perspective to sustain or implement policies and programs in accordance with a more sustainable approach based on the elimination of stigma and the promotion of political participation of people who use drugs. In short, drug policies based on human rights.

Mental Health and Benzodiazepine Use Among Patients on Chronic Opioid Therapy

INTRODUCTION

Higher daily doses of opioids as well as co-prescription of benzodiazepines have been associated with risk of overdose. The current study characterizes prescribing patterns in a family medicine practice with regard to patient mental health diagnoses, benzodiazepine prescriptions, morphine milligram equivalent opioid dose, and patient demographics.

METHODS

Patients on chronic opioid therapy were studied in 2018 and 2019. Mental health diagnoses, opioid dose, benzodiazepine prescriptions and demographic characteristics were extracted from the electronic health record. Data were compared between years and logistic regression was used to determine which patient characteristics were associated with likelihood of decreased opioid dose.

RESULTS

A total of 387 patients were prescribed chronic opioid therapy in 2018, and 231 in 2019. In 2018, 49.9% of patients prescribed chronic opioids had mental health diagnoses. In 2019, this proportion rose to 92.2%. In 2019, 205 of the original 387 patients were still with the practice but were not prescribed chronic opioids. Among the factors studied, psychiatric diagnosis and higher opioid dose were associated with a significantly lower likelihood of tapering doses.

DISCUSSION

As practices taper or de-prescribe opioids, or implement harm reduction methods such as de-prescribing benzodiazepines, it is important to understand patient characteristics and their relationship to success with tapering. This study adds to the evidence that odds of successfully tapering opioids may be significantly impacted by patients' mental health diagnosis and opioid dose.

A qualitative study of repeat naloxone administrations during opioid overdose intervention by people who use opioids in New York City

BACKGROUND

Take-home naloxone (THN) kits have been designed to provide community members (including people who use drugs, their families and/or significant others) with the necessary resources to address out-of-hospital opioid overdose events. Kits typically include two doses of naloxone. This 'twin-pack' format means that lay responders need information on how to use each dose. Advice given tends to be based on dosage algorithms used by medical personnel. However, little is currently known about how and why people who use drugs, acting as lay responders, decide to administer the second dose contained within single THN kits. The aim of this article is to explore this issue.

METHODS

Data were generated from a qualitative semi-structured interview study that was embedded within a randomised controlled trial examining the risks and benefits of Overdose Education and Naloxone Distribution (OEND) training in New York City (NYC). Analysis for this article focuses upon the experiences of 22 people who use(d) opioids and who provided repeat naloxone administrations (RNA) during 24 separate overdose events. The framework method of analysis was used to compare the time participants believed had passed between each naloxone dose administered ('subjective response interval') with the 'recommended response interval' (2-4 minutes) given during OEND training. Framework analysis also charted the various reasons and rationale for providing RNA during overdose interventions.

RESULTS

When participants' subjective response intervals were compared with the recommended response interval for naloxone dosing, three different time periods were reported for the 24 overdose events: i. 'two doses administered in under 2 minutes' (n = 10); ii. 'two doses administered within 2-4 minutes' (n = 7), and iii. 'two doses administered more than 4 minutes apart' (n = 7). A variety of reasons were identified for providing RNA within each of the three categories of response interval. Collectively, reasons for RNA included panic, recognition of urgency, delays in retrieving naloxone kit, perceptions of recipients' responsiveness/non-responsiveness to naloxone, and avoidance of Emergency Response Teams (ERT).

CONCLUSION

Findings suggest that decision-making processes by people who use opioids regarding how and when to provide RNA are influenced by factors that relate to the emergency event. In addition, the majority of RNA (17/24) occurred outside of the recommended response interval taught during OEND training. These findings are discussed in terms of evidence-based intervention and 'evidence-making intervention' with suggestions for how RNA guidance may be developed and included within future/existing models of OEND training.

Communicating risk differences between electronic and combusted cigarettes: the role of the FDA-mandated addiction warning and a nicotine fact sheet

INTRODUCTION

The US Food and Drug Administration requires e-cigarettes to carry a nicotine addiction warning. This research compared the effects of messages communicating comparative risk of electronic and combusted cigarettes (CR messages) with and without the mandated warning and tested the effects of showing a nicotine fact sheet (NFS) before exposure to CR messages with warning.

METHOD

In an online experiment, 1528 US adult smokers were randomised to one of four conditions: (1) three CR messages, (2) three CR messages in condition one with an addiction warning, (3) an NFS followed by the three messages in condition 2 and (4) control messages. Outcomes included message reactions and perceived effectiveness, e-cigarette-related and cigarette-related beliefs and behavioural intentions and nicotine-related beliefs.

RESULTS

CR messages with and without an addiction warning did not differ. The NFS condition produced higher odds of correctly understanding the risk of nicotine and stronger beliefs that switching to e-cigarettes could reduce health risks (response efficacy) than other treatments. Compared with control, all messages made it more likely for people to report e-cigarettes are less harmful than cigarettes and increased response efficacy and switch intentions to e-cigarettes. Only NFS condition increased correct beliefs about the risk of nicotine and self-efficacy about switching to e-cigarettes.

CONCLUSION

Including an addiction warning on CR messages did not reduce intentions to switch to e-cigarettes. Communicating accurate risk of nicotine together with CR messages and addiction warning increased smokers' self-efficacy beliefs about switching completely to e-cigarettes, making it a potentially promising antitobacco communication strategy.

[Consumption of psychoactive substances: from punishment to care]

Although the consumption of psychoactive substances is a practice that dates back to the earliest days of humanity, in the last century it has become an issue that has gained attention from the scientific community, State agencies of control, professionals in a number of diverse settings, and society at large. Despite being a complex issue with multiple manifestations, there has been a tendency to reduce it to a question of disease or of crime; nonetheless, not all forms of consumption constitute problematic substance use, nor do they produce substance use disorders. Bearing this in mind, the call for papers on "the consumption of psychoactive substances: from punishment to care" brings together research that contributes both knowledge and actions that are contrary to punitive responses, which unfortunately remain prevalent in society.

Safer opioid distribution in response to the COVID-19 pandemic

COVID-19 has turned the world upside down in a very short period of time. The impact of COVID-19 will disproportionately effect people who are least able to protect themselves and this will include people who use drugs. The arrival of the COVID-19 pandemic comes at time when North America is in the midst of a protracted overdose epidemic caused by a toxic illegal drug supply. Overdose deaths are likely to rise when people are isolated, social support programs are cut back, and the illicit drug supply is further compromised. Safer opioid distribution in response to a toxic street drug supply is a pragmatic and effective way to reduce overdose deaths. COVID-19 makes such an approach even more urgent and compelling.

[Managing pleasures and harms: An ethnographic study of drug consumption in public spaces, homes and drug consumption rooms]

Drug consumption rooms (DCR) aim to facilitate consumption in hygienic and safe conditions. However, users also consume drugs in public spaces and homes generating incremental risk for health. To strengthen our understanding of consumption practices, we conducted an ethnographic study in different consumption locations in Barcelona, including DCRs, public spaces, and homes. Focusing on consumption practices and narratives, we conducted participant observation and interviewed 16 DCR users. Our findings show that different consumption spaces allow users to experiment different types of pleasures. In addition, consumption in each type of location is associated with various types of harms, which are managed by users by self-regulating their practices. These aspects, therefore, must be taken into account to design harm reduction action aligned with users' practices.

[Drug policies in the Brazilian context: an intersectional analysis of "Cracolândia" in São Paulo, Brazil]

From the analysis of a specific conjuncture, "Cracolândia" in São Paulo, Brazil, and the "De Braços Abertos" program, this article discusses the complex relationships between drug use and the formulation of public policies directed to the care of users. In methodological terms, this work is based on the qualitative research by using semi-structured interviews with thirteen key informants. The empirical material was analyzed from the content thematic analysis and the intersectionality perspective, especially from the theoretical contributions of the "difference" category. The results point out that "differences" are marked by gender, race and social position in the society, reinforcing stigmas and their different impacts on social relations. This paper contributes to the debate on the need to formulate different approaches to the specific needs and demands of populations or social classification categories regarding drug public policy.
