Background: While people with substance use disorders, including people who inject drugs (PWID), experience increased risk for COVID-19 infection and adverse outcomes, COVID-19 vaccination rates among PWID are consistently lower than those observed in the general population. Offering COVID-19 vaccines at syringe services programs (SSPs) has been proposed as a critical strategy to increase vaccine uptake among this population. We explored the experiences of frontline staff at an SSP in Miami, Florida implementing onsite COVID-19 vaccines.

Advances in antiretroviral therapy (ART) have made it possible for persons with human immunodeficiency virus (HIV) to live a lifespan approaching that of people without HIV, without progressing to AIDS or transmitting HIV to sexual partners or infants. There is, therefore, increasing emphasis on maintaining health throughout the lifespan. To receive optimal medical care and achieve desired outcomes, persons with HIV must be consistently engaged in care and able to access uninterrupted treatment, including ART.

Background: Buprenorphine is a first-line treatment for opioid use disorder (OUD), essential for reducing opioid overdose mortality and improving treatment retention. Despite federal policies that mandate the acceptance of buprenorphine in recovery residences, individuals in South Florida taking this medication often face significant barriers to admission. This study uses a secret shopper survey to examine whether federal policies regarding prescribed buprenorphine use are being violated in South Florida recovery residences.

Methadone is an opioid receptor agonist medication used in the treatment of opioid use disorder (OUD). Geographic distance to opioid treatment programs (OTPs) is a major barrier to treatment, given requirements for direct observation of dosing and periodic drug screens, and 'methadone treatment deserts' are defined as a public transit threshold of 30 minutes. The purpose of this study was to examine public transit access to methadone treatment for participants of a syringe services program (SSP) in Miami-Dade County, Florida.

Syringe Services Programs (SSPs) provide evidence-based services like drug use equipment to prevent infectious disease, overdose prevention education, and naloxone distribution to people who use drugs (PWUD). However, inadequate funding threatens provision of these interventions. This study aimed to document how the current funding landscape impacted determinants of SSP implementation, particularly describing financial and staffing barriers, facilitators, and proposed strategies, using qualitative methods informed by three implementation research frameworks.

People with HIV (PWH) frequently suffer from Opioid (OP) Use Disorder (OUD). In an investigation of the impact of OUD on underlying immune dysfunction in PWH, we previously reported that OP use exacerbates inflammation in virally controlled PWH followed in the Infectious Diseases Elimination Act (IDEA) Syringe Services Program (SSP). Unexpectedly, Flu vaccination-induced antibody responses in groups with OUD were superior to PWH without OUD.

Background: Syringe services programmes (SSPs) are an evidence-based strategy to reduce infectious diseases and deliver overdose prevention interventions for people who use drugs. They face regulatory, administrative, and funding barriers that limit their implementation in the US, though the federal government recently began providing funding to support these efforts. In this study we aim to understand whether the organisational characteristics of SSPs are associated with the provision of syringe and other overdose response strategies.

Introduction: Despite having a high risk of acquiring sexually transmitted infections, people who inject drugs (PWID) often do not receive recommended HPV screenings due to barriers to healthcare. Guideline-based cervical HPV screening and vaccination can prevent cervical cancer. Low-cost, low-barrier methods for cancer screening and prevention are important for vulnerable communities such as PWID.

Article Synopsis
  • - Xylazine, an alpha-2 adrenergic agonist, has become a contaminant in fentanyl and is associated with naloxone-resistant overdoses and unusual wounds in drug users; a unique case in Florida involved a woman with xylazine-induced wounds confirmed through a test strip at a syringe services program.
  • - The woman, 43, presented to a student-run clinic for care of multiple ulcerations on her forearms, and after receiving treatment, she returned seven weeks later with worsening wounds; xylazine was confirmed in her urine during this second visit.
  • - Many people who use drugs (PWUD) struggle to access traditional healthcare due to stigma and lack of insurance, highlighting the urgent need for improved access

To describe the current financial health of syringe services programs (SSPs) in the United States and to assess the predictors of SSP budget levels and associations with delivery of public health interventions. We surveyed all known SSPs operating in the United States from February to June 2022 (n = 456), of which 68% responded (n = 311). We used general estimating equations to assess factors influencing SSP budget size and estimated the effects of budget size on multiple measures of SSP services.

Background: Tele-harm reduction (THR) is a telehealth-enhanced, peer-led, harm reduction intervention delivered within a trusted syringe services program (SSP) venue. The primary goal of THR is to facilitate linkage to care and rapid, enduring virologic suppression among people who inject drugs (PWID) with HIV. An SSP in Miami, Florida, developed THR to circumvent pervasive stigma within the traditional healthcare system.

Background: People who use drugs (PWUD) experience elevated HIV risk and numerous barriers to facility-based HIV testing. HIV self-testing (HIVST) could circumvent many of those barriers and is acceptable among PWUD, yet HIVST implementation for PWUD is limited. Service providers' perspectives on specific HIVST delivery strategies could help increase availability for PWUD.

Article Synopsis
  • A study conducted at a student-run clinic in Miami found that 55.9% of patients who inject drugs tested positive for xylazine in their urine samples.
  • The presence of xylazine was linked to factors such as unsheltered homelessness, wounds, and positive tests for hepatitis C, fentanyl, and MDMA.
  • The findings highlight the growing prevalence of xylazine in the Southeastern U.S. and emphasize the need for better screening to address associated risks for people who inject drugs.

Introduction: The expanded capacity of syringe services programs (SSPs) in the USA to integrate telehealth services was largely related to flexibility of buprenorphine prescription in response to the COVID-19 pandemic. SSPs demonstrated the potential of using telehealth to reach participants with both medical and non-medical services. The present study examines the implementation of medical and non-medical telehealth-based health services in 2020 at SSPs in the USA and organizational characteristics associated with adopting specific telehealth services.
