Background
This study examined the prevalence of screening and brief intervention (SBI) for alcohol use disorder (AUD) risk in samples of adult drinkers in three middle-income countries (Brazil, China, South Africa), and the extent to which meeting criteria for AUD risk was associated with SBI.
Methods
Cross-sectional survey data were collected from adult samples in two cities in each country in 2018. Survey measures included past-year alcohol use, the CAGE assessment for AUD risk, talking to a health care professional in the past year, alcohol use screening by a health care professional, receiving advice about drinking from a health care professional, and sociodemographic characteristics. The prevalence of SBI was determined for past-year drinkers in each country and for drinkers who had talked to a health care professional. Logistic regression analyses were conducted to examine whether meeting criteria for AUD risk was associated with SBI when adjusting for sociodemographic characteristics.
Results
Among drinkers at risk for AUD, alcohol use screening rates ranged from 6.7% in South Africa to 14.3% in Brazil, and brief intervention rates ranged from 4.6% in South Africa to 8.2% in China. SBI rates were higher among drinkers who talked to a health care professional in the past year. In regression analyses, AUD risk was positively associated with SBI in China and South Africa, and with brief intervention in Brazil.
Conclusion
Although the prevalence of SBI among drinkers at risk for AUD in Brazil, China, and South Africa appears to be low, it is encouraging that these drinkers were more likely to receive SBI.

In the US, medication assisted treatment, particularly with office-based buprenorphine, has been an important component of opioid dependence treatment among patients with iatrogenic addiction to opioid analgesics. The predictors of initiating buprenorphine for addiction among opioid analgesic patients have not been well-described.
We conducted a time-to-event analysis using data from the North Carolina (NC) Prescription Drug Monitoring Program (PDMP). Our outcome of interest was time-to-initiation of sublingual buprenorphine. Our study population was a prospective cohort of all state residents receiving a full-agonist opioid analgesic between 2011 and 2015. Predictors of initiation of sublingual buprenorphine examined included: age, gender, cumulative pharmacies and prescribers utilized, cumulative opioid intensity (defined as cumulative opioid exposure divided by duration of opioid exposure), and benzodiazepine dispensing.
Of 4.3 million patients receiving opioid analgesics in NC between 2011 and 2015 (accumulated 8.30 million person-years of follow-up), and a total of 28,904 patients initiated buprenorphine formulations intended for addiction treatment (overall rate 3.48 per 1,000 person-years). In adjusted multivariate models, the utilization of 3 or more pharmacies (HR: 2.93; 95% CI: 2.82, 3.05) or 6 or more controlled substance prescribers (HR: 12.09; 95% CI: 10.76, 13.57) was associated with buprenorphine initiation. A dose-response relationship was observed for cumulative opioid intensity (HR in highest decile relative to lowest decile: 5.05; 95% CI: 4.70, 5.42). Benzodiazepine dispensing was negatively associated with buprenorphine initiation (HR: 0.63; 95% CI: 0.61, 0.65).
Opioid analgesic patients utilizing multiple prescribers or pharmacies are more likely to initiate sublingual buprenorphine. This finding suggests that patients with multiple healthcare interactions are more likely to be treated for high-risk opioid use, or may be more likely to be identified and treated for addiction. Future research should utilize prescription monitoring program data linked to electronic health records to include diagnosis information in analytic models.

BackgroundProject Lazarus (PL) is a seven-strategy, community-coalition-based intervention designed to reduce opioid overdose and dependence. The seven strategies include: community education, provider education, hospital emergency department policy change, diversion control, support programs for patients with pain, naloxone policies, and addiction treatment expansion. PL was originally developed in Wilkes County, NC. It was made available to all counties in North Carolina starting in March 2013 with funding of up to $34,400 per county per year. We examined the association between PL implementation and 1) overall dispensing rate of opioid analgesics, and 2) utilization of buprenorphine. Buprenorphine is often used in connection with medication assisted treatment (MAT) for opioid dependence.MethodsObservational interrupted time series analysis of 100 counties over 2009–2014 (n = 7200 county-months) in North Carolina. The intervention period was March 2013–December 2014. 74 of 100 counties implemented the intervention. Exposure data sources comprised process surveys, training records, Prescription Drug Monitoring Program (PDMP) data, and methadone treatment program quality data. Outcomes were PDMP-derived counts of opioid prescriptions and buprenorphine patients. Incidence Rate Ratios were estimated with adjusted GEE Poisson regression models of all seven PL strategies.ResultsIn adjusted models, diversion control efforts were positively associated with increased dispensing of opioid analgesics (IRR: 1.06; 95% CI: 1.03, 1.09). None of the other PL strategies were associated with reduced prescribing of opioid analgesics. Support programs for patients with pain were associated with a non-significant decrease in buprenorphine utilization (IRR: 0.93; 95% CI: 0.85, 1.02), but addiction treatment expansion efforts were associated with no change in buprenorphine utilization (IRR: 0.98; 95% CI: 0.91, 1.06).ConclusionsImplementation of PL strategies did not appreciably reduce opioid dispensing and did not increase buprenorphine utilization. These results are consistent with previous findings of limited impact of PL strategies on overdose morbidity and mortality. Future studies should analyze the uptake of MAT using a more expansive view of institutional barriers, treating community coalition activity around MAT as an effect modifier.

Objective To examine the association of parental school involvement with reductions in adolescent substance initiation among Latino immigrant youth. Background Parental school involvement is an important determinant of children's academic achievement. Likewise, academic achievement is associated with multiple adolescent health risk behaviors. Little research has examined whether parental school involvement is associated with adolescent drug use, and no research has examined this link among Latino immigrant youth. Method Using a census of Latino students (N = 661; mean age = 13.1 years) in 12 urban middle schools, we used a multilevel model with zero‐inflated outcomes to test whether (a) parental school involvement is inversely associated with alcohol, tobacco, and other drug use; (b) school‐level parental involvement affects individual‐level drug use; and (c) child gender moderates these associations. Results Parental school involvement was negatively associated with lifetime prevalence of all substances and with increases in the age of first alcohol use. School‐level parental involvement was negatively associated with lifetime prevalence of substance use and age of first use for girls and marginally significant with boys. Conclusion Parental school involvement is a promising target for prevention efforts to reduce early‐onset substance use. Implications Parental school involvement may address multiple negative outcomes in youth even for youth whose parents are relatively uninvolved, and may increase program dosage.

Youth alcohol use (AU) is a major global health problem. Tomando Buenas Decisiones (TBD), an adapted family-based prevention program based on the existing Guiding Good Choices program, was piloted and tested in Zacatecas, Mexico. We examined the effects of the TBD program on reducing family risk for youth AU. We used a quasi-experimental design comprising a sample of 268 parents with children 8 to 16 years. All participants were working actively in one of five Zacatecan private companies. Inverse probability weighting based on intervention status, along with censoring propensity scores, was used to estimate the difference in risk levels between intervention participants and wait-listed controls. Latent growth curve modeling was used to analyze the intervention impact on three first-order risk factors (i.e., positive attitudes for drug use, family conflict, poor family management) and a combined measure of general family risk (i.e., a second-order factor using the three first-order risk factors) at baseline, post-intervention, and 3-month follow-up. Relative to wait-listed controls, the TBD program was efficacious in reducing positive attitudes for drug use, family conflict, poor family management, and general family risk levels. However, at the 3-month follow-up, effects on positive attitudes toward drug use were no longer significant. Findings from this study address a gap in establishing efficacious preventive interventions for youth AU in Latin America. We anticipate that our study’s findings could help inform prevention efforts to reduce leading youth alcohol-related harms such as drunk driving, and domestic violence among Mexican adolescents and their families.
Highlights
Tomando Buenas Decisiones
has the potential to reduce family risks associated with alcohol use among Mexican youth.
Inverse probability weighting improves the effect-estimation of preventive interventions in non-experimental conditions.
Testing the proximal effects of preventive programs is an appropriate strategy to validate its adaptability in other contexts.

BackgroundIn response to increasing opioid overdoses, US prevention efforts have focused on prescriber education and supply, demand and harm reduction strategies. Limited evidence informs which interventions are effective. We evaluated Project Lazarus, a centralised statewide intervention designed to prevent opioid overdose.MethodsObservational intervention study of seven strategies. 74 of 100 North Carolina counties implemented the intervention. Dichotomous variables were constructed for each strategy by county-month. Exposure data were: process logs, surveys, addiction treatment interviews, prescription drug monitoring data. Outcomes were: unintentional and undetermined opioid overdose deaths, overdose-related emergency department (ED) visits. Interrupted time-series Poisson regression was used to estimate rates during preintervention (2009–2012) and intervention periods (2013–2014). Adjusted IRR controlled for prescriptions, county health status and time trends. Time-lagged regression models considered delayed impact (0–6 months).ResultsIn adjusted immediate-impact models, provider education was associated with lower overdose mortality (IRR 0.91; 95% CI 0.81 to 1.02) but little change in overdose-related ED visits. Policies to limit ED opioid dispensing were associated with lower mortality (IRR 0.97; 95% CI 0.87 to 1.07), but higher ED visits (IRR 1.06; 95% CI 1.01 to 1.12). Expansions of medication-assisted treatment (MAT) were associated with increased mortality (IRR 1.22; 95% CI 1.08 to 1.37) but lower ED visits in time-lagged models.ConclusionsProvider education related to pain management and addiction treatment, and ED policies limiting opioid dispensing showed modest immediate reductions in mortality. MAT expansions showed beneficial effects in reducing ED-related overdose visits in time-lagged models, despite an unexpected adverse association with mortality.

Abstract
Objective
To examine the impact of three sequential statewide policy and legislative interventions on opioid prescribing practices among privately insured individuals in North Carolina.
Methods
An interrupted time series approach was used to examine level and trajectory changes of new and prevalent opioid prescription rates, days’ supply, and daily morphine milligram equivalents before and after implementation of a 1) prescription drug monitoring program, 2) state medical board initiative, and 3) legislative action. Analyses were conducted using individual-level claims data from a large private health insurance provider serving North Carolina residents, ages 18–64 years, from January 2006 to August 2018.
Results
Rates of new and prevalent prescription opioid patients were relatively unaffected by the prescription monitoring program but sharply declined in the months immediately following both medical board (−3.7 new and −19.3 prevalent patients per 10,000 person months) and legislative (−14.1 new and −26.7 prevalent patients) actions. Among all opioid prescriptions, days’ supply steadily increased on average over the study period but declined after legislative action (−1.5 days’ supply per year).
Conclusions
The voluntary prescription drug monitoring program launched in 2010 only marginally affected opioid prescribing patterns on its own, but its redeployment as an investigative and clinical tool in multifaceted public policy approaches by the state medical board and legislature later in the decade plausibly contributed to notable declines in prescription rates and days’ supply. This study lends new emphasis to the importance of enforcement mechanisms for state and national policies seeking to reverse this critical public health crisis.

Rapid reduction or discontinuation of long-term opioid therapy may increase risk of opioid overdose or opioid use disorder (OUD). Current guidelines for chronic pain management caution against rapid dose reduction but are based on limited evidence.
To characterize the association between rapid reduction or abrupt discontinuation of opioid therapy (vs maintained or gradual reduction) and incidence of opioid overdose and OUD among patients prescribed high-dose, long-term opioid therapy (HDLTOT).
This retrospective cohort study was conducted among patients aged 18 to 64 years who were prescribed HDLTOT (≥90 daily morphine milligram equivalents for ≥90% of 90 days) from January 2006 to September 2018, with follow-up up to 4 years after cohort entry. Claims data were drawn from a large private health insurer in North Carolina and analyzed from March 1, 2006, to September 30, 2018.
Time-varying exposure of rapid dose reduction or discontinuation (>10% dose reduction/week) vs maintenance, increase, or gradual reduction or discontinuation.
The main outcome was incident opioid overdose (fatal or nonfatal) or diagnosed OUD. Inverse probability-weighted cumulative incidence of outcomes were estimated using the cumulative incidence function and hazard ratios (HRs) using marginal structural Fine-Gray models as a function of rapid dose tapering or discontinuation (vs gradual reduction or discontinuation or maintained or increased), accounting for competing risks.
A total of 19 443 patients (median [IQR] age, 49 [41-55] years; 10 073 [51.8%] men) who received HDLTOT were identified. Rapid reduction or discontinuation was associated with higher risk of fatal and nonfatal overdoses compared with gradual reduction after the first year (year 1: HR, 1.43; 95% CI, 0.94-2.18; years 2-4: HR, 1.95; 95% CI, 1.31-2.90). There was no association between rapid reduction or discontinuation and diagnosed OUD through 2 years of follow-up; however, the hazard of incident OUD among patients exposed to rapid tapering or discontinuation was greater 25 to 48 months after the start of follow-up (HR, 1.28; 95% CI, 1.01-1.63).
In this cohort study, rapid dose reduction or discontinuation was associated with increased risk of opioid overdose and OUD during long-term follow-up. These findings reinforce prior concerns about safety of rapid dose reductions for patients receiving HDLTOT and highlight the need for caution when reducing opioid doses.

Underage drinking represents a major global health problem. Given the crisis that underage drinking represents, Tomando Buenas Decisiones, a family-based prevention program, was adapted and piloted in Mexico based on the existing Guiding Good Choices program. Although family-based interventions in the USA are promising for preventing underage drinking, little is known about how adapted versions of these interventions may work in low-middle income countries, such as in Latin America. The present study examined whether baseline individual, familial, and cultural factors predict participants’ engagement and attendance in an adapted program for preventing underage drinking in Zacatecas, Mexico. The study was conducted with a sample of 178 parents who participated in the adapted program and were employed at local private companies. Latent growth curve modeling was used to analyze (a) change in engagement, (b) predictors of engagement, and (c) predictors of attendance. Results indicated that perceived engagement evidenced a significant linear increase throughout the intervention. Participants’ familism values, such as perceived family as referents and family support, at baseline predicted both initial levels of and change in engagement. Perceived familial obligation also predicted change in engagement. Attendance was negatively predicted by male gender, by perceived stress, and by perceived familial obligations among women only. Poor family management, and perceived familial obligations among men, positively predicted attendance. Our findings have important implications for the conceptualization of engagement and attendance in family-based preventive interventions for underage drinking among Hispanics. Researchers interested in implementing interventions in Latin America can use these findings to better comprehend how and for whom adapted family-based preventive interventions work.

Locked Down: Economic and Health Effects of COVID-19 Response on Residents of a South African Township
2024
BackgroundLittle research has examined how pandemics affect residents in under-resourced communities. This study investigated how COVID-19 and lockdown policies affected residents of Alexandra, one of Johannesburg, South Africa’s lowest-income townships.MethodsWe conducted a telephone survey May 11–22, 2020, while the lockdown and alcohol ban were in effect, of a spatially stratified sample of 353 adult Alexandra residents drawn randomly from voter registration, credit card application, and prior studies’ sampling frames. We examined economic consequences; health experiences, including COVID-19 exposure and mental health symptoms; alcohol use; and personal experiences with violence.ResultsRespondents were aged 18 to 89 and 47% female. About 70% of those employed before the lockdown were no longer working. Over half of households lost at least one source of income. About 50% of respondents reported stockpiling food. A majority reported price rises and declines in availability of food. Smaller percentages reported such changes for other items. Over 80% reported stress or anxiety, or depression due to the pandemic. The prevalence of past-week alcohol use fell from over 50% before the lockdown to less than 10% during the lockdown. Self-reported physical violence victimization increased.DiscussionCOVID-19 and the lockdown disrupted Alexandra residents’ lives through unemployment, lost income, mental health problems, and increased violence. The differences between these outcomes and those in more advantaged communities deserve investigation. Research should also seek to identify tailored responses to effectively address the challenges of marginalized communities that often have limited resources to deal with pandemics and policies to contain them.
