Exploring the impact of the COVID-19 pandemic on healthcare and substance use service access among women who inject drugs: a qualitative study.

BACKGROUND: The COVID-19 pandemic disrupted healthcare and substance use services engagement, including primary and mental health services as well as residential and outpatient drug treatment. Women who inject drugs (WWID) face known barriers to healthcare and substance use service engagement, which pre-date the COVID-19 pandemic. The impact of COVID-19 on WWID's engagement with healthcare and substance use services, however, remains understudied. METHODS: To explore the impact of the COVID-19 pandemic on service-seeking and utilization, we conducted in-depth interviews with 27 cisgender WWID in Baltimore, Maryland, in April-September 2021. Iterative, team-based thematic analysis of interview transcripts identified disruptions and adaptations to healthcare and substance use services during the COVID-19 pandemic. RESULTS: The COVID-19 pandemic disrupted service engagement for WWID through service closures, pandemic safety measures restricting in-person service provision, and concerns related to contracting COVID-19 at service sites. However, participants also described various service adaptations, including telehealth, multi-month prescriptions, and expanded service delivery modalities (e.g., mobile and home delivery of harm reduction services), which overwhelmingly increased service engagement. CONCLUSION: To build upon service adaptations occurring during the pandemic and maximize expanded access for WWID, it is vital for healthcare and substance use service providers to continue prioritizing expansion of service delivery modality options, like telehealth and the provision of existing harm reduction services through alternative platforms (e.g., mobile services), that facilitate care continuity and increase coverage.

Trends in handwashing behaviours for COVID-19 prevention: Longitudinal evidence from online surveys in 10 sub-Saharan African countries

Handwashing is essential for respiratory virus prevention, but uptake of handwashing in the context of the SARS-CoV-2 pandemic remains under-explored. This study examines trends in and determinants of handwashing practices for COVID-19 prevention in 10 countries in West, East, and Southern Africa. Data are derived from an online global Facebook survey assessing COVID-19 knowledge, attitudes, and practices, fielded in July (Round 1) and November 2020 (Round 2). Adults ≥18 years (N = 29,964) were asked if they practiced handwashing with soap and water in the past week to prevent COVID-19. Design-corrected F-statistics compared knowledge and practice of handwashing, at country and regional levels, between survey rounds. A country-level fixed-effects logistic regression model then identified socio-demographic and ideational correlates of handwashing at Round 2. Most participants were >30 years-old, men, post-secondary educated, and urban residents. Between survey rounds, handwashing prevalence declined significantly across regions and in each country, from a 14% decline (Δ84%–70%) in Tanzania to a 3% decline (Δ92%–89%) in South Africa. Handwashing was higher among participants aged >30 years (Adjusted Odds Ratio [aOR] = 1.25, 95% confidence interval [95%CI]: 1.15–1.35) and with post-secondary education (aOR = 1.62, 95%CI: 1.49–1.77) but lower among men (aOR = 0.71, 95%CI: 0.64–0.78). Ideational factors associated with handwashing included perceived effectiveness of handwashing (aOR = 2.17, 95%CI: 2.00–2.36), knowing someone diagnosed with COVID-19 (aOR = 1.28, 95%CI: 1.18–1.40), and perceived importance of personal action for COVID-19 prevention (aOR = 2.93;95%CI: 2.60–3.31). Adjusting for socio-demographic and ideational factors, country-level marginal probabilities of handwashing ranged from 67% in Tanzania to 91% in South Africa in Round 2. COVID-19 prevention messages should stress the importance of handwashing, coupled with mask use and physical distancing, for mitigating respiratory disease transmission. Behaviour change communications should be sensitive to resource heterogeneities in African countries, which shape opportunities for sustainable handwashing behaviours.

Safety in Solitude? Competing Risks and Drivers of Solitary Drug Use among Women who Inject Drugs and Implications for Overdose Detection.

BACKGROUND AND AIMS: Solitary drug use (SDU) can amplify risks of fatal overdose. We examined competing risks and drivers of SDU, as well as harm reduction strategies implemented during SDU episodes, among women who inject drugs (WWID). DESIGN: A cross-sectional qualitative study, including telephone and face-to-face in-depth interviews. SETTING: Baltimore City, Maryland, USA. PARTICIPANTS: Twenty-seven WWID, (mean age: 39 years, 67% White, 74% injected drugs daily) recruited via outreach and street intercept (April-September 2021). MEASUREMENTS: Interviews explored the physical (i.e., indoor/private, outdoor/public) and social (i.e., alone, accompanied) risk environments in which drug use occurred. Guided by the principles of emergent design, we used thematic analysis to interrogate textual data, illuminating women's preferences/motivations for SDU and strategies for minimizing overdose risks when using alone. FINDINGS: Many participants reported experiences with SDU, despite expressed preferences for accompanied drug use. SDU motivations clustered around three primary drivers: (1) avoiding opioid withdrawal, (2) preferences for privacy when using drugs, and (3) safety concerns, including threats of violence. Participants nevertheless acknowledged the dangers of SDU and, at times, took steps to mitigate overdose risk, including naloxone possession, communicating to peers when using alone ("spotting"), and using drugs in public spaces. CONCLUSIONS: Women who inject drugs appear to engage frequently in solitary drug use due to constraints of the physical and social environments in which they use drugs. They express a preference for accompanied drug use in most cases and report implementing strategies to mitigate their overdose risk, especially when using drugs alone.

Provider Perspectives on HIV Pre-Exposure Prophylaxis Service Disruptions and Adaptations During the COVID-19 Pandemic in Baltimore, Maryland: A Qualitative Study.

The COVID-19 pandemic continues driving unprecedented disruptions to health care provision, including HIV pre-exposure prophylaxis (PrEP) services. We explored service provider experiences promoting and prescribing PrEP to marginalized populations during the COVID-19 pandemic in Baltimore, Maryland. In February to April 2021, we facilitated four virtual focus group discussions with 20 PrEP providers, representing various professional cadres and practice settings. Employing an iterative, team-based thematic analysis, we identified salient enablers and constraints to PrEP promotion, initiation, and maintenance in the COVID-19 era, along with innovative adaptations to PrEP service delivery. Discussants described attenuated demands for PrEP early in the pandemic, exemplified by high PrEP discontinuation rates. This was attributed to changes in clients' sexual behaviors and shifting priorities, including caregiving responsibilities, during the pandemic. Substantial systems-level disruptions impacting PrEP provision were identified, including outreach service suspension, personnel shortages, and facility restrictions on face-to-face visits. Providers emphasized that these disruptions, though occurring early in the pandemic, had protracted impacts on PrEP accessibility. The transition to telemedicine rendered health care services, including PrEP, more accessible/convenient to some clients and expeditious to providers. However, structural barriers to telehealth engagement (telephone/internet access), coupled with limitations of the virtual care environment (difficulty establishing rapport), impeded efforts to equitably promote and prescribe PrEP. Expanding the PrEP outreach workforce and availing alternatives to telemedicine (e.g., community-based PrEP provision, specimen self-collection) could facilitate PrEP care continuity, especially as COVID-19 transitions from an acute to a protracted health crisis.

A Systematic Review of Coronavirus Disease 2019 Vaccine Efficacy and Effectiveness Against Severe Acute Respiratory Syndrome Coronavirus 2 Infection and Disease.

Billions of doses of coronavirus disease 2019 (COVID-19) vaccines have been administered globally, dramatically reducing severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) incidence and severity in some settings. Many studies suggest vaccines provide a high degree of protection against infection and disease, but precise estimates vary and studies differ in design, outcomes measured, dosing regime, location, and circulating virus strains. In this study, we conduct a systematic review of COVID-19 vaccines through February 2022. We included efficacy data from Phase 3 clinical trials for 15 vaccines undergoing World Health Organization Emergency Use Listing evaluation and real-world effectiveness for 8 vaccines with observational studies meeting inclusion criteria. Vaccine metrics collected include protection against asymptomatic infection, any infection, symptomatic COVID-19, and severe outcomes including hospitalization and death, for partial or complete vaccination, and against variants of concern Alpha, Beta, Gamma, Delta, and Omicron. We additionally review the epidemiological principles behind the design and interpretation of vaccine efficacy and effectiveness studies, including important sources of heterogeneity.

Family Planning in Zambia: An Investment Pillar for Economic Development: [version 2;peer review: 2 approved]

Family planning represents a ‘best buy’ in global efforts to achieve sustainable development and attain improvements in sexual and reproductive health. By meeting contraceptive needs of all women, significant public health impact and development gains accrue. At the same time, governments face the complex challenge of allocating finite resources to competing priorities, each of which presents known and unknown challenges and opportunities. Zambia has experienced a slow but steady increase in contraceptive prevalence, with slight decline in total fertility rate (TFR), over the past 20 years. Drawing from the Zambian context, including a review of current policy solutions, we present a case for making investments in voluntary family planning (FP), underpinned by a human rights framework, as a pillar for accelerating development and socio-economic advancement. Through multilevel interventions aimed at averting unintended pregnancies, Zambia – and other low- and middle-income countries – can reduce their age dependency ratios and harness economic growth opportunities awarded by the demographic dividend while improving the health and quality of life of the population.

Curating the Evidence About COVID-19 for Frontline Public Health and Clinical Care: The Novel Coronavirus Research Compendium.

The public health crisis created by the COVID-19 pandemic has spurred a deluge of scientific research aimed at informing the public health and medical response to the pandemic. However, early in the pandemic, those working in frontline public health and clinical care had insufficient time to parse the rapidly evolving evidence and use it for decision-making. Academics in public health and medicine were well-placed to translate the evidence for use by frontline clinicians and public health practitioners. The Novel Coronavirus Research Compendium (NCRC), a group of >60 faculty and trainees across the United States, formed in March 2020 with the goal to quickly triage and review the large volume of preprints and peer-reviewed publications on SARS-CoV-2 and COVID-19 and summarize the most important, novel evidence to inform pandemic response. From April 6 through December 31, 2020, NCRC teams screened 54 192 peer-reviewed articles and preprints, of which 527 were selected for review and uploaded to the NCRC website for public consumption. Most articles were peer-reviewed publications (n = 395, 75.0%), published in 102 journals; 25.1% (n = 132) of articles reviewed were preprints. The NCRC is a successful model of how academics translate scientific knowledge for practitioners and help build capacity for this work among students. This approach could be used for health problems beyond COVID-19, but the effort is resource intensive and may not be sustainable in the long term.
