Associations between short-term ambient temperature exposure and emergency department visits for amphetamine, cocaine, and opioid use in California from 2005 to 2019.

Substance use disorder is a growing public health challenge in the United States. People who use drugs may be more vulnerable to ambient heat due to the effects of drugs on thermoregulation and their risk environment. There have been limited population-based studies of ambient temperature and drug-related morbidity. We examined short-term associations between daily ambient temperature and emergency department (ED) visits for use or overdose of amphetamine, cocaine and opioids in California during the period 2005 to 2019. Daily ZIP code-level maximum, mean, and minimum temperature exposures were derived from 1-km data Daymet products. A time-stratified case-crossover design was used to estimate cumulative non-linear associations of daily temperature for lag days 0 to 3. Stratified analyses by patient sex, race, and ethnicity were also conducted. The study included over 3.4 million drug-related ED visits. We found positive associations between daily temperature and ED visits for all outcomes examined. An increase in daily mean temperature from the 50th to the 95th percentile was associated with ED visits for amphetamine use (OR = 1.072, 95% CI: 1.058, 1.086), cocaine use (OR = 1.044, 95% CI: 1.021, 1.068 and opioid use (OR = 1.041, 95% CI: 1.025, 1.057). Stronger positive associations were also observed for overdose: amphetamine overdose (OR = 1.150, 95% CI: 1.085, 1.218), cocaine overdose (OR = 1.159, 95% CI: 1.053, 1.276), and opioid overdose (OR = 1.079, 95% CI: 1.054, 1.106). In summary, people who use stimulants and opioids may be a subpopulation sensitive to short-term higher ambient temperature. Mitigating heat exposure can be considered in harm reduction strategies in response to the substance use epidemic and global climate change.

Refusal to accept emergency medical transport following opioid overdose, and conditions that may promote connections to care.

BACKGROUND: Opioid overdose is a leading cause of death in the United States. Emergency medical services (EMS) encounters following overdose may serve as a critical linkage to care for people who use drugs (PWUD). However, many overdose survivors refuse EMS transport to hospitals, where they would presumably receive appropriate follow-up services and referrals. This study aims to (1) identify reasons for refusal of EMS transport after opioid overdose reversal; (2) identify conditions under which overdose survivors might be more likely to accept these services; and (3) describe solutions proposed by both PWUD and EMS providers to improve post-overdose care. METHODS: The study comprised 20 semi-structured, qualitative in-depth interviews with PWUD, followed by two semi-structured focus groups with eight EMS providers. RESULTS: PWUD cited intolerable withdrawal symptoms; anticipation of inadequate care upon arrival at the hospital; and stigmatizing treatment by EMS and hospital providers as main reasons for refusal to accept EMS transport. EMS providers corroborated these descriptions and offered solutions such as titration of naloxone to avoid harsh withdrawal symptoms; peer outreach or community paramedicine; and addressing provider burnout. PWUD stated they might accept EMS transport after overdose reversal if they were offered ease for withdrawal symptoms, at either a hospital or non-hospital facility, and treated with respect and empathy. CONCLUSION: Standard of care by EMS and hospital providers following overdose reversal should include treatment for withdrawal symptoms, including buprenorphine induction; patient-centered communication; and effective linkage to prevention, treatment, and harm reduction services.

"Caught with a body" yet protected by law? Calling 911 for opioid overdose in the context of the Good Samaritan Law.

BACKGROUND: To address soaring opioid overdose fatality rates, 41U.S. states have passed Good Samaritan Laws (GSLs) extending legal immunity to overdose bystanders who call for emergency assistance. This study, conducted during the period that followed implementation of a GSL, aimed to characterize current factors determining the decision to call for emergency medical help (911) at the scene of an overdose with specific attention to exploring the role of the GSL as one such factor in decision-making. METHODS: We conducted 22 in-depth interviews with needle exchange program clients in Baltimore, MD. RESULTS: Most participants reported calling 911 or witnessing a 911 call after drug overdose, but widely remained fearful of arrest for drug or paraphernalia possession, homicide, outstanding warrants, and/or trespassing. These concerns were underpinned by a history of police maltreatment and threat, and strong distrust of police; concerns which were specifically related to perceptions of police conduct at the scene of an overdose as well as perceptions of police conduct in general. Additional considerations included: fear of losing housing, informal shelter or custody of children; encountering social stigma; and facing violent and fatal repercussions at the hands of local drug dealers. Additionally, some participants did not perceive a significant enough medical risk to call 911. Two thirds of participants were unaware of the GSL. Some believed a GSL would positively impact law enforcement behaviour and increase the likelihood of a bystander call; but due to distrust of police, others believed the GSL would have little influence on bystander decisions. CONCLUSION: Insights from overdose bystanders during the post-implementation period of a Good Samaritan Law demonstrate persistent deterrents to bystanders calling 911 after overdose. Additional measures are needed to align policy aims with lived experiences of overdose bystanders, and to achieve overdose prevention aims.

Exploring Multilevel Factors for Family Engagement in Home Visiting Across Two National Models.

The associations of family, home visitor and site characteristics with family engagement within the first 6 months were examined. The variation in family engagement was also explored. Home visiting program participants were drawn from 21 Healthy Families America sites (1707 families) and 9 Nurse-Family Partnership sites (650 families) in New Jersey. Three-level nested generalized linear mixed models assessed the associations of family, home visitor and site characteristics with family receipt of a high dose of services in the first 6 months of enrollment. A family was considered to have received a high dose of service in the first 6 months of enrollment if they were active at 6 months and had received at least 50% of their expected visits in the first 6 months. In general, both home visiting programs engaged, at a relatively high level (Healthy Families America (HFA) 59%, Nurse-Family Partnership (NFP) 64%), with families demonstrating high-risk characteristics such as lower maternal education, maternal smoking, and maternal mental health need. Home visitor characteristics explained more of the variation (87%) in the receipt of services for HFA, while family characteristics explained more of the variation (75%) in the receipt of services for NFP. At the family level, NFP may improve the consistency with which they engage families by increasing retention efforts among mothers with lower education and smoking mothers. HFA sites seeking to improve engagement consistency should consider increasing the flexible in home visitor job responsibilities and examining the current expected-visit policies followed by home visitors on difficult-to-engage families.

Gender-based violence against adolescent and young adult women in low- and middle-income countries.

PURPOSE: Gender-based violence (GBV) is a global health and human rights issue with individual and social determinants. Youth are considered high risk; national influences include norms, policies and practices. By age, nation, and region, we contrast key GBV indicators, specifically intimate partner violence (IPV) and forced sexual debut among adolescent and young adult women using Demographic and Health Surveys across low- and middle-income countries. METHODS: National prevalence estimates were generated among adolescents (15-19 years) and young adults (20-24 years) for lifetime and the past-year physical and sexual IPV among ever-married/cohabitating women (30 nations) and forced sexual debut among sexually experienced women (17 nations). Meta-analyses provided regional estimates and cross-national comparisons, and compared the past-year IPV prevalence among adolescent and young adult women to adult women. RESULTS: An estimated 28% of adolescent and 29% of young adult women reported lifetime physical or sexual IPV, most prevalent in the East and Southern Africa region. Regional and cross-national variation emerged in patterns of violence by age; overall, young adult women demonstrated higher risk for the past-year IPV relative to adult women (meta-analysis odds ratio, 1.20; 95% confidence interval, 1.10-1.37) and adolescents had a comparable risk (meta-analysis odds ratio, 1.07; 95% confidence interval, .91-1.23). Forced sexual debut was estimated at 12% overall, highest in the East and Southern Africa region. CONCLUSIONS: GBV is pervasive among adolescent and young adult women in low- and middle-income countries. The unique risk to youth varies across nations, suggesting an age-place interaction. Future research is needed to clarify contextual determinants of GBV. Findings provide direction for integrating youth within GBV prevention efforts.

Depression outcomes associated with an intervention implemented in employment training programs for low-income adolescents and young adults.

IMPORTANCE: Recent estimates indicate that 6.5 million adolescents and young adults in the United States are neither in school nor working. These youth have significant mental health concerns that require intervention. OBJECTIVE: To determine whether a mental health intervention, integrated into an employment training program that serves adolescents and young adults disconnected from school and work, can reduce depressive symptoms and improve engaged coping strategies. DESIGN, SETTING, AND PARTICIPANTS: A quasi-experimental study was conducted; 512 adolescents and young adults newly enrolling in one employment training program site were intervention participants, while 270 youth from a second program site were enrolled as controls. Participants were aged 16 to 23 years and not in foster care. Study recruitment took place from September 1, 2008, to May 31, 2011, with follow-up data collection occurring for 12 months after recruitment. Propensity score matching adjusted for observed baseline differences between the intervention and control groups. MAIN OUTCOMES AND MEASURES: Depressive symptoms measured on a Center for Epidemiologic Studies Depression Scale (CES-D) and engaged coping strategies. RESULTS: The mean age of participants was 19 years, 93.7% were African American, and 49.4% were male. Six- and 12-month follow-up rates were 61.0% (n = 477) and 56.8% (n = 444), respectively. Males in the intervention group with high baseline depressive symptoms exhibited a statistically significant decrease in depressive symptoms at 12 months (5.64-point reduction in CES-D score; 95% CI, -10.30 to -0.96; P = .02) compared with similar males in the control group. A dosage effect was observed at 12 months after the intervention, whereby males with greater intervention exposure showed greater improvement in depressive symptoms compared with similar males with lower intervention doses (effect on mean change in CES-D score, -3.37; 95% CI, -6.72 to -0.09; P = .049). Males and females in the intervention group were more likely than participants in the control group to increase their engaged coping skills, with statistically significant differences found for males (effect on mean change in CES-D score, 0.32; 95% CI, 0.14-0.50; P = .001) and females (effect on mean change in CES-D score, 0.19; 95% CI, 0.01-0.37; P = .047) at 12 months. CONCLUSIONS AND RELEVANCE: Given the growing number of adolescents and young adults using employment training programs and the mental health needs of this population, increased efforts should be made to deliver mental health interventions in these settings that usually focus primarily on academic and job skills. Ways to extend the effect of intervention for females and those with lower levels of depressive symptoms should be explored.

Sexually transmitted infection risk behaviors in rural Thai adolescents and young adults: support for sex- and age-specific interventions.

Sexually transmitted infection (STI) prevalence and risks in a sample of rural Thai adolescents and young adults (14-29 years) were examined. Unprotected sex with a casual partner conferred the greatest risk for prevalent STIs, particularly for younger adolescents, and alcohol use increased the STI risk for women but not for men.

Predictors of incident and recurrent participation in the sale or delivery of drugs for profit amongst young methamphetamine users in Chiang Mai Province, Thailand, 2005-2006.

BACKGROUND: Despite Thailand's war on drugs, methamphetamine ("yaba" in Thai) use and the drug economy both thrive. This analysis identifies predictors of incident and recurrent involvement in the sale or delivery of drugs for profit amongst young Thai yaba users. METHODS: Between April 2005 and June 2006, 983 yaba users, ages 18-25, were enrolled in a randomized behavioural intervention in Chiang Mai Province (415 index and 568 of their drug network members). Questionnaires administered at baseline, 3-, 6-, 9-, and 12-month follow-up visits assessed socio-demographic factors, current and prior drug use, social network characteristics, sexual risk behaviours and drug use norms. Exposures were lagged by three months (prior visit). Outcomes included incident and recurrent drug economy involvement. Generalized linear mixed models were fit using GLIMMIX (SASv9.1). RESULTS: Incident drug economy involvement was predicted by yaba use frequency (adjusted odds ratio [AOR]: 1.05; 95% confidence interval [CI]: 1.01, 1.10), recent incarceration (AOR: 2.37; 95% CI: 1.07, 5.25) and the proportion of yaba-using networks who quit recently (AOR: .34; 95% CI: .15, .78). Recurrent drug economy involvement was predicted by age (AOR: 0.81; 95% CI: 0.68, 0.96), frequency of yaba use (AOR: 1.06; 95% CI: 1.02, 1.09), drug economy involvement at the previous visit (AOR: 2.61; CI: 1.59, 4.28), incarceration in the prior three months (AOR: 2.29; 95% CI: 1.07, 4.86), and the proportion of yaba-users in his/her network who quit recently (AOR: .38; 95% CI: .20, .71). CONCLUSION: Individual drug use, drug use in social networks and recent incarceration were predictors of incident and recurrent involvement in the drug economy. These results suggest that interrupting drug use and/or minimizing the influence of drug-using networks may help prevent further involvement in the drug economy. The emergence of recent incarceration as a predictor for both models highlights the need for more appropriate drug rehabilitation programmes and demonstrates that continued criminalization of drug users may fuel Thailand's yaba epidemic.

Variations in sexual risks in drug users: emerging themes in a behavioral context.

Drug users are an especially complex population among those studied in HIV risk behavior research. Although injection drug use accounts for over one third of the cumulative HIV transmission in the United States, the scope of the direct and indirect impacts of all drug use is difficult to quantify, especially in relation to attributing HIV to drug use directly, via parenteral exposures, or indirectly, through unsafe sex. Important behavioral issues such as social and drug network overlaps, partner selection, and the combinations of illicit drugs with erectile dysfunction medications have added complexity to the study of sexual behavior in drug users. This review covers recent substantive research in the United States and Canada on current themes in sexual risk behavior in injection drug and non-injection drug users. We address gender, situational, and sexual preference factors that may influence sexual behaviors affecting HIV risk by class of drug and route of administration. Special attention is paid to minority populations, both sexual and racial/ethnic, as their marginalized role in contemporary society places special barriers to risk reduction.

Heterosexual anal sex among female drug users: U.S. national compared to local Long Beach, California data.

Receptive anal sex is a well-studied Human Immunodeficiency Virus (HIV) high-risk behavior among gay and bisexual men, yet previous research indicates that more women than men may be at risk from heterosexual anal sex (HAS). 1991-1996 data from the National Institute on Drug Abuse (NIDA) Cooperative Agreement (CA) were analyzed to model risk for women who reported having had HAS in the 30 days prior to interview. This model was then tested on recent data (2001-2006) collected on women in Long Beach, California. The multivariate model predicting anal sex in the NIDA CA dataset included sex trading; risk perception for HIV; ever had gonorrhea; sex while high; and drugs used in the last 30 days. African American race/ethnicity and older age were inversely associated with HAS. Risk factors common to both samples of women were number of days used amphetamine in the last month and risk perception for HIV.
