Clinical trials show that doxycycline post-exposure prophylaxis (DoxyPEP) significantly reduces the risk of bacterial sexually transmitted infections (STIs), especially syphilis and chlamydia, in cisgender men who have sex with men and transgender women. Real-world data suggest DoxyPEP may be beneficial for other populations disproportionately affected by STIs. Given the ongoing STI epidemic we recommend discussing DoxyPEP with all eligible patients.

Background: Benzodiazepines and opioids are among the most frequently misused psychoactive substances, but their patterns of co-use (polysubstance use) in rural areas are unclear. As resources to address substance use are disproportionally scarce in rural areas, a better understanding of this polysubstance use is critical to allocate and direct interventions.

Methods: The Rural Opioid Initiative comprises 8 research cohorts spanning 10 states and 65 rural counties.

Introduction: People who use drugs (PWUD) are at risk of HIV infection, but the frequency and distribution of transmission-associated behaviors within rural communities is not well understood. Further, while interventions designed to more explicitly affirm individuals' sexual orientation and behaviors may be more effective, descriptions of behavior variability by orientation are lacking. We sought to describe how disease transmission behaviors and overdose risk vary by sexual orientation and activity among rural PWUD.

Background: Methamphetamine use is disproportionately high in rural settings, with rates increasing during the COVID-19 pandemic. While syringe service programs reduce disease transmission among people who inject drugs, limited research exists around the value of smoking equipment, specifically pipes, in minimizing harms associated with rural methamphetamine use.

Methods: We conducted semi-structured interviews with people who use methamphetamine in rural southern Illinois.

Article Synopsis
  • In recent rural U.S. studies, individuals who use drugs (PWUD) are increasingly combining opioids with stimulants like methamphetamine and cocaine.
  • Among 2,705 PWUD surveyed, 74% reported using both opioids and stimulants, with 76% having undergone hepatitis C virus (HCV) testing.
  • Those who used opioids alone had lower rates of HCV testing, and those using both opioids and stimulants were less likely to have received anti-HCV medication compared to those using other drugs.

Introduction: Recovery support workers (RSWs) who provide social support interventions for people who use drugs (PWUD) often face challenges that can jeopardize the well-being, efficacy and sustainability of this essential workforce. To date, little has been reported on the types of implementation strategies used to support RSWs. We describe and evaluate a multifaceted implementation strategy package to support Reducing Opioid Mortality in Illinois (ROMI), a paired peer recovery coach and case manager (PRC-CM) intervention for PWUD with recent criminal-legal involvement in urban and rural settings.

Background: Over the last two decades, houselessness and drug-related epidemics both have expanded from urban to rural regions across the United States (US). However, our understanding of the relationship between rural houselessness, drug use, and drug-related harms has not kept pace. The current study addresses this gap by describing houselessness among a large cohort of people who use drugs (PWUD) from rural communities across 10 states.

Background: The United States' (US) opioid overdose epidemic has evolved into a combined stimulant/opioid epidemic, a pattern driven in part by mitigating opioid overdose risk, variable substance availability, and personal preferences. This study aimed to investigate the association between self-reported substance preference (heroin or methamphetamine) and behavioral/health outcomes among individuals who used both heroin and methamphetamine in the rural US.

Methods: The Rural Opioid Initiative is a consortium of 8 research cohorts from 10 states and 65 rural counties that recruited individuals reporting past 30-day injection of any substance or opioid substance use by any route from 1/2018 to 3/2020.

Introduction: To expand access to naloxone, the state of Illinois implemented a standing order allowing registered pharmacies to dispense the drug without an individual prescription. To participate under the standing order, pharmacies were required to opt in through a formal registration process. In our study we aimed to evaluate the availability and price of naloxone at registered pharmacies.

The objective of this study was to understand barriers to healthcare and social service utilization among older adults residing in rural areas who use drugs. A cross-sectional survey of persons who use opioids or inject drugs in rural counties with high overdose rates across ten states was conducted. For this analysis, participants were restricted to only the 375 individuals aged 50 and older.

Article Synopsis
  • Accurate estimates of drug use and related health issues among marginalized populations, especially persons who use drugs (PWUD) in rural areas, are essential for effective intervention and understanding health disparities.* -
  • The study used respondent-driven sampling (RDS) to recruit PWUD and evaluated the assumptions behind RDS to ensure the reliability of its prevalence estimates, analyzing various drug usage variables and health indicators among participants.* -
  • Findings indicated a median participant age of 34, with opioids being the most commonly used drug; however, recruitment chains often lacked sufficient length for reliable sample representation, and different weighting methods showed minimal differences in prevalence estimates.*

Issues: To date, there has been no synthesis of research addressing the scale and nuances of the opioid epidemic in racial/ethnic minority populations in the United States that considers the independent and joint impacts of dynamics such as structural disadvantage, provider bias, health literacy, cultural norms and various other risk factors.

Approach: Using the "risk environment" framework, we conducted a scoping review on PubMed, Embase and Google Scholar of peer-reviewed literature and governmental reports published between January 2000 and February 2024 on the nature and scale of opioid use, opioid prescribing patterns, and fatal overdoses among racial/ethnic minorities in the United States, while also examining macro, meso and individual-level risk factors.

Key Findings: Results from this review illuminate a growing, but fragmented, literature lacking standardisation in racial/ethnic classification and case reporting, specifically in regards to Indigenous and Asian subpopulations.
