Sociopolitical Diagnostic Tools to Understand National and Local Response Capabilities and Vulnerabilities to Epidemics and Guide Research into How to Improve the Global Response to Pathogens.

The AIDS and COVID-19 pandemics demonstrated that nations at similar economic development levels varied widely in their capacity to protect the health of their residents. For AIDS, Britain and Australia brought gay representatives into official counsels and adopted harm reduction far more rapidly than the United States or Spain, and East African countries responded more effectively than South Africa or the Democratic Republic of the Congo. National responses to COVID-19 varied widely, with New Zealand, China, and Vietnam more effective than Italy, Brazil, or the United States. Further, as phylogenetic research has demonstrated, these pandemics spread from one country to another, with those that responded poorly acting as sources for mutations and potentially sources of transmission to countries with more effective responses. Many observers expressed surprise at the poor responses of the United States to COVID-19, but in retrospect the cutbacks in public health funding at state and national levels made it clear that this was a predictable weakness even in addition to the political vacillations that crippled the US and Brazilian responses. In a time of global sociopolitical and climate instability, it is important to measure and conduct research into spatial and time variations in 1. public health and medical funding, 2. social influence networks, social cohesion and trust, and stigmatization, 3. income inequality, 4. social conflict, and 5. other factors that affect responsiveness to pandemics.

The urgent need to implement point-of-care RNA testing for hepatitis C virus to support elimination.

Hepatitis C virus (HCV) elimination is an important global public health goal. However, the United States (US) is not on track to meet the World Health Organization's 2030 targets for HCV elimination. Recently, the White House proposed an HCV elimination plan that includes point-of-care (POC) HCV RNA testing, which is currently in use in many countries, but is not approved in the US. POC HCV RNA testing is crucial for implementing community-based testing, and for enabling test-and-treat programs, assessing cure, and monitoring for reinfection.. In this commentary, we review the status of POC HCV RNA testing in the US, discuss factors that are needed for successful implementation, and issue specific public health and policy recommendations that would allow for the use of POC HCV RNA testing to support HCV elimination.

Syringe Service Program Perspectives on Barriers, Readiness, and Programmatic Needs to Support Rollout of the COVID-19 Vaccine.

BACKGROUND: We explored syringe service program (SSP) perspectives on barriers, readiness, and programmatic needs to support coronavirus disease 2019 (COVID-19) vaccine uptake among people who use drugs. METHODS: We conducted an exploratory qualitative study, leveraging an existing sample of SSPs in the United States. Semistructured, in-depth interviews were conducted with SSP staff between February and April 2021. Interviews were analyzed using a Rapid Assessment Process, an intensive, iterative process that allows for rapid analysis of time-sensitive qualitative data. RESULTS: Twenty-seven SSPs completed a qualitative interview. Many SSP respondents discussed that COVID-19 vaccination was not a priority for their participants because of competing survival priorities, and respondents shared concerns that COVID-19 had deepened participant mistrust of health care. Most SSPs wanted to participate in COVID-19 vaccination efforts; however, they identified needed resources, including adequate space, personnel, and training, to implement successful vaccine programs. CONCLUSIONS: Although SSPs are trusted resources for people who use drugs, many require additional structural and personnel support to address barriers to COVID-19 vaccination among their participants. Funding and supporting SSPs in the provision of COVID-19 prevention education and direct vaccine services should be a top public health priority.

Association between follow-up blood cultures for gram-negative bacilli bacteremia and length of hospital stay and duration of antibiotic treatment: A propensity score-matched cohort study.

OBJECTIVE: It remains unclear whether a follow-up blood culture (FUBC) for gram-negative bacilli (GNB) bacteremia should be routinely or selectively performed. To evaluate the value of the practice, we analyzed the association between current FUBC practices and length of stay, antibiotic treatment duration, and in-hospital mortality. DESIGN: Retrospective cohort study. SETTING: The study was conducted in 4 acute-care hospitals in New York City. PATIENTS: The study included hospitalized adults with GNB bacteremia between 2017 and 2018. METHODS: An FUBC was defined as a blood culture performed between 24 hours and 7 days after an initial blood culture positive for GNB. Using propensity scores for FUBCs performed, patients were matched 1:1 for outcome comparison. RESULTS: In total, 376 hospitalized adults with GNB bacteremia met eligibility criteria. Among them, FUBCs were performed in 271 patients (72%). After propensity score matching, we analyzed 87 pairs of patients with and without an FUBC to compare outcomes. The median length of stay was longer among patients with FUBCs than patients without FUBCs (9 days vs 7 days; P = .017). The median duration of antibiotic treatment was also longer among patients with FUBCs than patients without FUBCs (8 vs 6 days; P = .007). No statistically significant difference was observed in in-hospital mortality between patients with and without an FUBC (odds ratio, 0.37; 95% confidence interval, 0.08-1.36). CONCLUSIONS: Current FUBC practices for GNB bacteremia were associated with prolonged length of stay and duration of antibiotic treatment. Further data to better inform selectivity criteria for FUBCs in GNB bacteremia are needed.

Availability of and Obstacles to Providing COVID-19 Vaccinations at Syringe Services Programs in the United States, 2021.

Many syringe services programs (SSPs) have established trusting, long-term relationships with their clients and are well situated to provide COVID-19 vaccinations. We examined characteristics and practices of SSPs in the United States that reported providing COVID-19 vaccinations to their clients and obstacles to vaccinating people who inject drugs (PWID). We surveyed SSPs in September 2021 to examine COVID-19 vaccination practices through a supplement to the 2020 Dave Purchase Memorial survey. Of 153 SSPs surveyed, 73 (47.7%) responded to the supplement; 24 of 73 (32.9%) reported providing on-site COVID-19 vaccinations. Having provided hepatitis and influenza vaccinations was significantly associated with providing COVID-19 vaccinations (70.8% had provided them vs 28.6% had not; P = .002). Obstacles to providing vaccination included lack of appropriate facilities, lack of funding, lack of trained staff, and vaccine hesitancy among PWID. SSPs are underused as vaccination providers. Many SSPs are well situated to provide COVID-19 vaccinations to PWID, and greater use of SSPs as vaccination providers is needed.

Barriers to engaging people who use drugs in harm reduction services during the COVID-19 pandemic: A mixed methods study of syringe services program perspectives.

BACKGROUND: Syringe services programs (SSPs) provide critical evidence-based public health services that decrease harms from drug use for people who use drugs (PWUD). Many SSPs have experienced significant and evolving COVID-19-related disruptions. We aimed to characterize the impacts of COVID-19 on SSP operations in the United States approximately one year into the pandemic. METHODS: Participating sites, selected from a national sample of SSPs, completed a semi-structured interview via teleconference and brief survey evaluating the impacts of COVID-19 on program operations. Data collection explored aspects of program financing, service delivery approaches, linkages to care, and perspectives on engaging PWUD in services one year into the pandemic. Interview data were analyzed qualitatively using Rapid Assessment Process. Survey data were analyzed using descriptive statistics and triangulated with qualitative findings. RESULTS: 27 SSPs completed study-related interviews and surveys between February 2021 - April 2021. One year into the pandemic, SSPs reported continuing to adapt approaches to syringe distribution in response to COVID-19, and identified multiple barriers that hindered their ability to engage program participants in services, including 1) isolation and decreased connectivity with participants, 2) resource restrictions that limit responsiveness to participant needs, 3) reduced capacity to provide on-site HIV/HCV testing and treatment linkages, and 4) changing OUD treatment modalities that were a "double-edged sword" for PWUD. Quantitative survey responses aligned with qualitative findings, highlighting increases in the number of syringes distributed, increases in mobile and home delivery services, and reductions in on-site HIV and HCV testing. CONCLUSION: These data illuminate persistent and cascading risks of isolation, reduced access to services, and limited engagement with program participants that resulted from COVID-19 and continue to create barriers to the delivery of critical harm reduction services. Findings emphasize the need to ensure SSPs have the resources and capacity to adapt to changing public health needs, particularly as the COVID-19 pandemic continues to evolve.

Responding to a surge in overdose deaths: perspectives from US syringe services programs.

BACKGROUND: US overdose deaths have reached a record high. Syringe services programs (SSPs) play a critical role in addressing this crisis by providing multiple services to people who use drugs (PWUD) that help prevent overdose death. This study examined the perspectives of leadership and staff from a geographically diverse sample of US SSPs on factors contributing to the overdose surge, their organization's response, and ongoing barriers to preventing overdose death. METHODS: From 2/11/2021 to 4/23/2021, we conducted semi-structured interviews with leadership and staff from 27 SSPs sampled from the North American Syringe Exchange Network directory. Interviews were transcribed and qualitatively analyzed using a Rapid Assessment Process. RESULTS: Respondents reported that increased intentional and unintentional fentanyl use (both alone and combined with other substances) was a major driver of the overdose surge. They also described how the COVID-19 pandemic increased solitary drug use and led to abrupt increases in use due to life disruptions and worsened mental health among PWUD. In response to this surge, SSPs have increased naloxone distribution, including providing more doses per person and expanding distribution to people using non-opioid drugs. They are also adapting overdose prevention education to increase awareness of fentanyl risks, including for people using non-opioid drugs. Some are distributing fentanyl test strips, though a few respondents expressed doubts about strips' effectiveness in reducing overdose harms. Some SSPs are expanding education and naloxone training/distribution in the broader community, beyond PWUD and their friends/family. Respondents described several ongoing barriers to preventing overdose death, including not reaching certain groups at risk of overdose (PWUD who do not inject, PWUD experiencing homelessness, and PWUD of color), an inconsistent naloxone supply and lack of access to intranasal naloxone in particular, inadequate funding, underestimates of overdoses, legal/policy barriers, and community stigma. CONCLUSIONS: SSPs remain essential in preventing overdose deaths amid record numbers likely driven by increased fentanyl use and COVID-19-related impacts. These findings can inform efforts to support SSPs in this work. In the face of ongoing barriers, support for SSPs-including increased resources, political support, and community partnership-is urgently needed to address the worsening overdose crisis.

Toward a Theory of the Underpinnings and Vulnerabilities of Structural Racism: Looking Upstream from Disease Inequities among People Who Use Drugs.

Structural racism is increasingly recognized as a key driver of health inequities and other adverse outcomes. This paper focuses on structural racism as an "upstream" institutionalized process, how it creates health inequities and how structural racism persists in spite of generations of efforts to end it. So far, "downstream" efforts to reduce these health inequities have had little success in eliminating them. Here, we attempt to increase public health awareness of structural racism and its institutionalization and sociopolitical supports so that research and action can address them. This paper presents both a theoretic and an analytic approach to how structural racism contributes to disproportionate rates of HIV/AIDS and related diseases among oppressed populations. We first discuss differences in disease and health outcomes among people who use drugs (PWUD) and other groups at risk for HIV from different racial and ethnic populations. The paper then briefly analyzes the history of racism; how racial oppression, class, gender and other intersectional divisions interact to create health inequities; and how structural racism is institutionalized in ways that contribute to disease disparities among people who use drugs and other people. It examines the processes, institutions and other structures that reinforce structural racism, and how these, combined with processes that normalize racism, serve as barriers to efforts to counter and dismantle the structural racism that Black, indigenous and Latinx people have confronted for centuries. Finally, we discuss the implications of this analysis for public health research and action to undo racism and to enhance the health of populations who have suffered lifetimes of racial/ethnic oppression, with a focus on HIV/AIDS outcomes.

Lessons from the First Wave of COVID-19 for Improved Medications for Opioid Use Disorder (MOUD) Treatment: Benefits of Easier Access, Extended Take Homes, and New Delivery Modalities.

Background Medications for Opioid Use Disorder (MOUD) are associated with important public health benefits. Program changes implemented in response to COVID-19 hold promise as ongoing strategies to improve MOUD treatment. Methods: MOUD patients on buprenorphine or methadone, providers, government regulators, and persons who use drugs not in MOUD were recruited in the Northeast region of the United States between June and October of 2020 via advertisements, fliers, and word of mouth. Semi-structured qualitative interviews were conducted. Interviews were professionally transcribed and thematically coded by two independent coders. Results: We conducted interviews with 13 people currently on buprenorphine, 11 currently on methadone, 3 previously on buprenorphine, 4 previously on methadone, and 6 who used drugs but had never been on MOUD. In addition, we interviewed MOUD providers, clinic staff, and government officials at agencies that regulate MOUD. Most participants found increased take-home doses, home medication delivery, and telehealth implemented during COVID-19 to be favorable, reporting that these program changes reduced travel time to clinics, facilitated retention in care, and reduced stigma associated with clinic attendance. However, some participants reported negative consequences of COVID-19, most notably, decreased access to basic resources, such as food, clothing, and harm reduction materials that had previously been distributed at some MOUD clinics. Conclusion: Access to and retention in MOUD can be lifesaving for persons using drugs. COVID-19-impelled program changes, including increased take-home doses, home medication delivery, and telehealth generally improved participants' experiences with MOUD. Making these permanent could improve retention in care.

Harm reduction and health services provided by syringe services programs in 2019 and subsequent impact of COVID-19 on services in 2020.

OBJECTIVES: This study describes harm reduction and health services provided by U.S syringe services programs (SSPs) in 2019 and changes in provision of those services in 2020. METHODS: SSPs were invited to participate in the Dave Purchase Memorial survey in August 2020. We collected programmatic data on services provided in 2019 and at the time of the survey in 2020. We conducted descriptive analyses using Chi-square and McNemar's tests. RESULTS: At the time of the survey, > 60% of SSPs reported increased monthly syringe and naloxone distribution and expansion of home-based and mail-based naloxone delivery in Fall 2020 compared to 2019. Approximately three-quarters of SSPs decreased or stopped providing on-site HIV and HCV testing. Nearly half of SSPs offering on-site medications for opioid use disorder (MOUD) in 2019 increased provision of MOUD in 2020. The proportion of SSPs offering on-site mental health care services and primary care services statistically significantly decreased from 2019 to Fall 2020, but telehealth offerings of these services increased. CONCLUSIONS: Many SSPs that offered health services in 2019 and remained operational in 2020 increased telehealth provision of mental health and primary care services, increased MOUD provision, and expanded harm reduction services, but most SSPs reduced or stopped on-site HIV and HCV testing. Sustaining SSP growth and innovation is paramount for preventing overdose deaths and HIV/HCV outbreaks after the deadliest year of the opioid epidemic in 2020.

Emerging Zoonotic Infections, Social Processes and Their Measurement and Enhanced Surveillance to Improve Zoonotic Epidemic Responses: A "Big Events" Perspective.

Zoonotic epidemics and pandemics have become frequent. From HIV/AIDS through COVID-19, they demonstrate that pandemics are social processes as well as health occurrences. The roots of these pandemics lie in changes in the socioeconomic interface between humanity and non-human host species that facilitate interspecies transmission. The degree to which zoonoses spread has been increased by the greater speed and extent of modern transportation and trade. Pre-existing sociopolitical and economic structures and conflicts in societies also affect pathogen propagation. As an epidemic develops, it can itself become a social and political factor, and change and interact with pre-existing sociobehavioral norms and institutional structures. This paper uses a "Big Events" approach to frame these processes. Based on this framework, we discuss how social readiness surveys implemented both before and during an outbreak might help public health predict how overall systems might react to an epidemic and/or to disease control measures, and thus might inform interventions to mitigate potential adverse outcomes or possibly preventing outbreaks from developing into epidemics. We conclude by considering what "pathways measures", in addition to those we and others have already developed, might usefully be developed and validated to assist outbreak and epidemic disease responses.

Cost of Hepatitis C care facilitation for HIV/Hepatitis C Co-infected people who use drugs.

BACKGROUND: Using data from a randomized trial, we evaluated the cost of HCV care facilitation that supports moving along the continuum of care for HIV/HCV co-infected individuals with substance use disorder. METHODS: Participants were HIV patients residing in the community, initially recruited from eight US hospital sites. They received HCV care facilitation (n = 51) or treatment as usual (n = 62) for up to six months. We used micro-costing methods to evaluate costs from the healthcare sector and patient perspectives in 2017 USD. We conducted sensitivity analyses varying care facilitator caseloads and examined offsetting savings using participant self-reported healthcare utilization. RESULTS: The average site start-up cost was $6320 (site range: $4320-$7000), primarily consisting of training. The mean weekly cost per participant was $20 (site range: $4-$30) for care facilitation visits and contacts, $360 (site range: $130- $700) for supervision and client outreach, and $70 (site range: $20-$180) for overhead. In sensitivity analyses applying a weekly caseload of 10 participants per care facilitator (versus 1-6 observed in the trial), the total mean weekly care facilitation cost from the healthcare sector perspective decreased to $110. Weekly participant time and travel costs averaged $7. There were no significant differences in other healthcare service costs between participants in the intervention and control arms. CONCLUSION: Weekly HCV care facilitation costs were approximately $450 per participant, but approximately $110 at a real-world setting maximum caseload of 10 participants per week. No healthcare cost offsets were identified during the trial period, although future savings might result from successful HCV treatment.

Care Facilitation Advances Movement Along the Hepatitis C Care Continuum for Persons With Human Immunodeficiency Virus, Hepatitis C, and Substance Use: A Randomized Clinical Trial (CTN-0064).

BACKGROUND: Direct-acting antivirals can cure hepatitis C virus (HCV). Persons with HCV/HIV and living with substance use are disadvantaged in benefiting from advances in HCV treatment. METHODS: In this randomized controlled trial, participants with HCV/HIV were randomized between February 2016 and January 2017 to either care facilitation or control. Twelve-month follow-up assessments were completed in January 2018.Care facilitation group participants received motivation and strengths-based case management addressing retrieval of HCV viral load results, engagement in HCV/HIV care, and medication adherence. Control group participants received referral to HCV evaluation and an offer of assistance in making care appointments. Primary outcome was number of steps achieved along a series of 8 clinical steps (eg, receiving HCV results, initiating treatment, sustained virologic response [SVR]) of the HCV/HIV care continuum over 12 months postrandomization. RESULTS: Three hundred eighty-one individuals were screened and 113 randomized. Median age was 51 years; 58.4% of participants were male and 72.6% were Black/African American. Median HIV-1 viral load was 27 209 copies/mL, with 69% having a detectable viral load. Mean number of steps completed was statistically significantly higher in the intervention group vs controls (2.44 vs 1.68 steps; χ 2 [1] = 7.36, P = .0067). Men in the intervention group completed a statistically significantly higher number of steps than controls. Eleven participants achieved SVR with no difference by treatment group. CONCLUSIONS: The care facilitation intervention increased progress along the HCV/HIV care continuum, as observed for men and not women. Study findings also highlight continued challenges to achieve individual-patient SVR and population-level HCV elimination. CLINICAL TRIALS REGISTRATION: NCT02641158.

"It's like 'liquid handcuffs": The effects of take-home dosing policies on Methadone Maintenance Treatment (MMT) patients' lives.

BACKGROUND: Methadone Maintenance Treatment (MMT) is widely recognized as one of the most effective ways of reducing risk of overdose, arrest, and transmission of blood-borne viruses like HIV and HCV among people that use opioids. Yet, MMT's use of restrictive take-home dose policies that force most patients to attend their clinic on a daily, or near-daily, basis may be unpopular with many patients and lead to low rates of treatment uptake and retention. In response, this article examines how clinics' take-home dosing policies have affected patients' experiences of treatment and lives in general. METHODS: This article is based on semi-structured, qualitative interviews with a variety of stakeholders in MMT. Interviews explored: reasons for engaging with, or not engaging with MMT; how MMT is conceptualized by patients and treatment providers (e.g., as harm reduction or route to abstinence and/or recovery); experiences with MMT; perception of barriers to MMT (e.g., organizational/regulatory, social) and how MMT might be improved to support peoples' substance use treatment needs and goals. RESULTS: Nearly all of the patients with past or present MMT use were highly critical of the limited access to take-home doses and consequent need for daily or near daily clinic attendance. Participants described how the use of restrictive take-home dose policies negatively impacted their ability to meet day-to-day responsibilities and also cited the need for daily attendance as a reason for quitting or avoiding OAT. Responses also demonstrate how such policies contribute to an environment of cruelty and stigma within many clinics that exposes this already-stigmatized population to additional trauma. CONCLUSIONS: Take-home dose policies in MMT are not working for a substantial number of patients and are reasonably seen by participants as degrading and dehumanizing. Revision of MMT regulations and policies regarding take home doses are essential to improve patient satisfaction and the quality and effectiveness of MMT as a key evidence-based treatment and harm reduction strategy.

Chronic High Risk Prescription Opioid Use Among Persons With HIV.

Persons with HIV (PWH) are a population at risk for adverse sequelae of opioid use. Yet, few studies have examined correlates of chronic high risk opioid use and its impact on HIV outcomes. Trends in prescribing patterns and identification of factors that impact the use of opioid prescriptions among PWH are crucial to determine prevention and treatment interventions. This study examined electronic medical records (EMR) of patients receiving HIV care to characterize prescribing patterns and identify risk factors for chronic high risk prescription opioid use and the impact on HIV outcomes among PWH in primary care from July 1, 2016-December 31, 2017. EMR were analyzed from 8,882 patients who were predominantly male and ethnically and racially diverse with half being 50 years of age or older. The majority of the 8,744 prescriptions (98% oral and 2% transdermal preparations) given to 1,040 (12%) patients were oxycodone (71%), 8% were morphine, 7% tramadol, 4% hydrocodone, 4% codeine, 2% fentanyl, and 4% were other opioids. The number of monthly prescriptions decreased about 14% during the study period. Bivariate analyses indicated that most demographic and clinical variables were associated with receipt of any opioid prescription. After controlling for patient socio-demographic characteristics and clinical factors, the odds of receipt of any prescription were higher among patients with pain diagnoses and opioid use and mental health disorders. In addition, the odds of receipt of high average daily morphine equivalent dose (MED) prescriptions were higher for patients with pain diagnoses. Lastly, patients with substance use disorders (SUD) had an increased likelihood of detectable viral load compared to patients with no SUD, after adjusting for known covariates. Our findings show that despite opioid prescribing guidelines and monitoring systems, additional efforts are needed to prevent chronic high risk prescriptions in patients with comorbid conditions, including pain-related, mental health and substance use disorders. Evidence about the risk for chronic high risk use based on prescribing patterns could better inform pain management and opioid prescribing practices for patients receiving HIV care.

Big Events theory and measures may help explain emerging long-term effects of current crises.

Big Events are periods during which abnormal large-scale events like war, economic collapse, revolts, or pandemics disrupt daily life and expectations about the future. They can lead to rapid change in health-related norms, beliefs, social networks and behavioural practices. The world is undergoing such Big Events through the interaction of COVID-19, a large economic downturn, massive social unrest in many countries, and ever-worsening effects of global climate change. Previous research, mainly on HIV/AIDS, suggests that the health effects of Big Events can be profound, but are contingent: Sometimes Big Events led to enormous outbreaks of HIV and associated diseases and conditions such as injection drug use, sex trading, and tuberculosis, but in other circumstances, Big Events did not do so. This paper discusses and presents hypotheses about pathways through which the current Big Events might lead to better or worse short and long term outcomes for various health conditions and diseases; considers how pre-existing societal conditions and changing 'pathway' variables can influence the impact of Big Events; discusses how to measure these pathways; and suggests ways in which research and surveillance might be conducted to improve human capacity to prevent or mitigate the effects of Big Events on human health.

Acceptability and Effectiveness of Hepatitis C Care at Syringe Service Programs for People Who Inject Drugs in New York City.

Introduction/Objectives: The incidence of hepatitis C (HCV) infection is rising among people who inject drugs (PWID). Even in the context of known HCV prevention and treatment strategies, some PWID remain unengaged in HCV care. This study aimed to identify and characterize experiences and perceptions of PWID regarding the acceptability and effectiveness of HCV testing and treatment at a local syringe service program (SSP). Methods: A total of 36 PWID participated in semi-structured interviews at an SSP in New York City. Interviews were audio-recorded, transcribed, and coded by three coders, following a constructivist grounded theory approach. Relevant themes were identified as they emerged from the data. Results: Interviews with PWID revealed three themes related to the impact of SSPs on HCV care: (1) non-stigmatizing SSP environments, (2) the role of SSPs in improving HCV knowledge, and (3) acceptability of SSPs as sites for HCV care among PWID. Discussion: This paper contributes to the ongoing understanding that SSPs provide a well-accepted source of HCV services for PWID. Participants believed that SSPs are accessible and effective sites for HCV care, and suggested that stigma among PWID continues to affect receipt of HCV care in traditional settings. Conclusions: Understanding attitudes and beliefs of PWID regarding the effectiveness of SSPs as sites for HCV care is crucial for the development of focused strategies to reduce HCV transmission, and to ultimately achieve HCV elimination. Given this, further research is warranted investigating how best to improve HCV care at harm reduction sites such as SSPs.
