Assessing the Potential Impact of Disruptions Due to COVID-19 on HIV Among Key and Lower-Risk Populations in the Largest Cities of Cameroon and Benin

Trends in different contraception methods among women attending the Melbourne Sexual Health Centre from 2011 to 2020

OBJECTIVES

The efficacy and availability of contraception have changed in the last several decades; however, unintended pregnancies continue to be an issue in Australia. This study aimed to describe trends in contraception in women attending a sexual health service over 9 years.

STUDY DESIGN

Repeated cross-sectional study.

METHODS

Women aged 16-49 years attending Melbourne Sexual Health Centre between 2011 and 2020 were included. Women were asked what methods of contraception they currently use. Contraception were categorised into long-acting reversible contraception (LARC; e.g. intrauterine devices and implants classified as highly effective), moderately effective contraception (e.g. oral contraception pill), less effective contraception (e.g. condom and withdrawal) and no contraception, as defined by US Centers for Disease Control and Prevention guidelines. Multivariable logistic regression was used to examine the factors associated with the use of moderate-high-efficacy contraception.

RESULTS

A total of 38,288 women were included with a median age of 25 (interquartile range: 22-29). Between 2011 and 2020, there was a decreasing trend in condom (63.3%-56.1%; Ptrend <0.001) and oral contraception (27.2%-20.5%; Ptrend <0.001) use, whilst there was an increasing trend in the use of LARCs: implant (4.6%-6.0%; Ptrend = 0.002) and intrauterine device (2.8%-11.8%; Ptrend <0.001). Increasing age was associated with decreased odds of using moderate-high-efficacy contraception (Ptrend <0.001). Compared with Oceanian-born women, Asian (adjusted odds ratios [aOR] = 0.63, 95% confidence interval [CI]: 0.56-0.72) and Middle Eastern-born women (aOR = 0.60, 95% CI: 0.48-0.74) had lower odds of using moderate-high-efficacy contraception, whilst European (aOR = 1.23, 95% CI:1.07-1.41) and North American-born women (aOR = 1.51, 95% CI: 1.22-1.87) had higher odds of using moderate-high-efficacy contraception.

CONCLUSIONS

Between 2011 and 2020, LARC use has increased, whilst less effective contraceptives, such as condom and oral contraception, have decreased among women at Melbourne Sexual Health Centre. Further research is required to understand age and ethnic disparities in contraception methods for future family planning programmes.

Scoping review of modelling studies assessing the impact of disruptions to essential health services during COVID-19

BACKGROUND

Studies assessing the indirect impact of COVID-19 using mathematical models have increased in recent years. This scoping review aims to identify modelling studies assessing the potential impact of disruptions to essential health services caused by COVID-19 and to summarise the characteristics of disruption and the models used to assess the disruptions.

METHODS

Eligible studies were included if they used any models to assess the impact of COVID-19 disruptions on any health services. Articles published from January 2020 to December 2022 were identified from PubMed, Embase and CINAHL, using detailed searches with key concepts including COVID-19, modelling and healthcare disruptions. Two reviewers independently extracted the data in four domains. A descriptive analysis of the included studies was performed under the format of a narrative report.

RESULTS

This scoping review has identified a total of 52 modelling studies that employed several models (n=116) to assess the potential impact of disruptions to essential health services. The majority of the models were simulation models (n=86; 74.1%). Studies covered a wide range of health conditions from infectious diseases to non-communicable diseases. COVID-19 has been reported to disrupt supply of health services, demand for health services and social change affecting factors that influence health. The most common outcomes reported in the studies were clinical outcomes such as mortality and morbidity. Twenty-five studies modelled various mitigation strategies; maintaining critical services by ensuring resources and access to services are found to be a priority for reducing the overall impact.

CONCLUSION

A number of models were used to assess the potential impact of disruptions to essential health services on various outcomes. There is a need for collaboration among stakeholders to enhance the usefulness of any modelling. Future studies should consider disparity issues for more comprehensive findings that could ultimately facilitate policy decision-making to maximise benefits to all.

Evaluation of the impact of COVID-19 in people coinfected with HIV and/or tuberculosis in low-income countries: study protocol for mixed methods research in Burkina Faso

BACKGROUND

An issue of particular concern is the impact of the 2019 novel coronavirus (2019 nCOV) on the people coinfected with the Human Immuno-deficiency Virus (HIV) and/or tuberculosis (TB). Unfortunately, this interaction has not been well explored in African despite the large proportion of these risk populations living with HIV and/or patients and/or tuberculosis (TB) in the African region. This study aims to design a research protocol for assessment of the impact of coronavirus disease 2019 (COVID-19) on these risk populations in response to COVID-19 strategic plans in Burkina Faso by generating serological, epidemiological, virological, clinical and socio-anthropological evidence-based data.

METHODS

A multidisciplinary research will be conducted in the city of Bobo-Dioulasso, Burkina Faso using mixed methods. Data will be collected from a cohort of people living with HIV and/or TB patients in the city (i) to determine the proportion of people with specific antibodies against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) using retrospective data ; (ii) to determine the proportion of people infected with Covid-19 and the dynamics of viral loads and antibodies in these people based on prospective data; (iii) to identify circulating SARS-COV-2 variants and novel biomarkers using prospective data ; (iv) to analyze perceptions, community experiences and response strategies during the public health emergencies imposed by COVID-19 through a qualitative study.

DISCUSSION

This study will generate factual and comprehensive data that will contribute in improving response strategies to COVID-19 and the other possible emerging diseases with keen interest on the risk populations living with HIV and/or TB infected patients.

Firth's Logistic Regression of Interruption in Treatment before and after the Onset of COVID-19 among People Living with HIV on ART in Two Provinces of DRC

The impact of the COVID-19 pandemic extends beyond the immediate physical effects of the virus, including service adjustments for people living with the human immunodeficiency virus (PLHIV) on antiretroviral therapy (ART). Purpose: To compare treatment interruptions in the year immediately pre-COVID-19 and after the onset of COVID-19 (10 April 2020 to 30 March 2021). Methods: We analyze quantitative data covering 36,585 persons with HIV who initiated antiretroviral treatment (ART) between 1 April 2019 and 30 March 2021 at 313 HIV/AIDS care clinics in the Haut-Katanga and Kinshasa provinces of the Democratic Republic of Congo (DRC), using Firth’s logistic regression. Results: Treatment interruption occurs in 0.9% of clients and tuberculosis (TB) is detected in 1.1% of clients. The odds of treatment interruption are significantly higher (adjusted odds ratio: 12.5; 95% confidence interval, CI (8.5−18.3)) in the pre-COVID-19 period compared to during COVID-19. The odds of treatment interruption are also higher for clients with TB, those receiving ART at urban clinics, those younger than 15 years old, and female clients (p < 0.05). Conclusions: The clients receiving ART from HIV clinics in two provinces of DRC had a lower risk of treatment interruption during COVID-19 than the year before COVID-19, attributable to program adjustments.

Using Microsimulation Modeling to Inform EHE Implementation Strategies in Los Angeles County

BACKGROUND

Pre-exposure prophylaxis (PrEP) is essential to ending HIV. Yet, uptake remains uneven across racial and ethnic groups. We aimed to estimate the impacts of alternative PrEP implementation strategies in Los Angeles County.

SETTING

Men who have sex with men, residing in Los Angeles County.

METHODS

We developed a microsimulation model of HIV transmission, with inputs from key local stakeholders. With this model, we estimated the 15-year (2021-2035) health and racial and ethnic equity impacts of 3 PrEP implementation strategies involving coverage with 9000 additional PrEP units annually, above the Status-quo coverage level. Strategies included PrEP allocation equally (strategy 1), proportionally to HIV prevalence (strategy 2), and proportionally to HIV diagnosis rates (strategy 3), across racial and ethnic groups. We measured the degree of relative equalities in the distribution of the health impacts using the Gini index (G) which ranges from 0 (perfect equality, with all individuals across all groups receiving equal health benefits) to 1 (total inequality).

RESULTS

HIV prevalence was 21.3% in 2021 [Black (BMSM), 31.1%; Latino (LMSM), 18.3%, and White (WMSM), 20.7%] with relatively equal to reasonable distribution across groups (G, 0.28; 95% confidence interval [CI], 0.26 to 0.34). During 2021-2035, cumulative incident infections were highest under Status-quo (n = 24,584) and lowest under strategy 3 (n = 22,080). Status-quo infection risk declined over time among all groups but remained higher in 2035 for BMSM (incidence rate ratio, 4.76; 95% CI: 4.58 to 4.95), and LMSM (incidence rate ratio, 1.74; 95% CI: 1.69 to 1.80), with the health benefits equally to reasonably distributed across groups (G, 0.32; 95% CI: 0.28 to 0.35). Relative to Status-quo, all other strategies reduced BMSM-WMSM and BMSM-LMSM disparities, but none reduced LMSM-WMSM disparities by 2035. Compared to Status-quo, strategy 3 reduced the most both incident infections (% infections averted: overall, 10.2%; BMSM, 32.4%; LMSM, 3.8%; WMSM, 3.5%) and HIV racial inequalities (G reduction, 0.08; 95% CI: 0.02 to 0.14).

CONCLUSIONS

Microsimulation models developed with early, continuous stakeholder engagement and inputs yield powerful tools to guide policy implementation.

The impact of COVID-19 on communicable and non-communicable diseases in Africa: a narrative review

The global pandemic of coronavirus disease 2019 (COVID-19) has disproportionately impacted global human health, economy, and security. Because of weaker health-care systems, existing comorbidities burden (HIV, malaria, tuberculosis, and non-communicable conditions), and poor socioeconomic determinants, initial predictive models had forecast a disastrous impact of COVID-19 in Africa in terms of transmission, severity, and deaths. Nonetheless, current epidemiological data seem not to have matched expectations, showing lower SARS-CoV-2 infection and fatality rates compared to Europe, the Americas and Asia. However, only few studies were conducted in low- and middle-income African settings where high poverty and limited access to health services worsen underlying health conditions, including endemic chronic infectious diseases such as HIV and tuberculosis. Furthermore, limited, and heterogeneous research was conducted to evaluate the indirect impact of the pandemic on general health services and on major diseases across African countries. International mitigation measures, such as resource reallocation, lockdowns, social restrictions, and fear from the population have had multi-sectoral impacts on various aspects of everyday life, that shaped the general health response. Despite the vast heterogeneity of data across African countries, available evidence suggests that the COVID-19 pandemic has severely impacted the control and prevention programs, the diagnosis capacity and the adherence to treatment of major infectious diseases (HIV, TB, and Malaria) - including neglected diseases - and non-communicable diseases. Future research and efforts are essential to deeply assess the medium- and long-term impact of the pandemic, and to implement tailored interventions to mitigate the standstill on decades of improvement on public health programs.

'We are not going anywhere': a qualitative study of Kenyan healthcare worker perspectives on adolescent HIV care engagement during the COVID-19 pandemic

INTRODUCTION

Adolescents living with HIV (ALHIV) may be vulnerable to widescale impacts of the COVID-19 pandemic and to health system responses which impact HIV care. We assessed healthcare worker (HCW) perspectives on impacts of the COVID-19 pandemic on adolescent HIV care delivery and engagement in western Kenya.

METHODS

We performed in-depth qualitative interviews with HCW at 10 clinical sites in the Academic Model Providing Access to Healthcare in Kenya, from January to March, 2021. Semistructured interviews ascertained pandemic-related impacts on adolescent HIV care delivery and retention.

RESULTS

Interviews were conducted with 22 HCWs from 10 clinics. HCWs observed adolescent financial hardships, unmet basic needs and school dropouts during the pandemic, with some adolescents relocating to rural homes, to partners or to the street. Marked increases in adolescent pregnancies and pregnancy complications were described, as well as barriers to family planning and antenatal care. Transportation challenges and restrictions limited access to care and prompted provision of multi-month refills, refills at local dispensaries or transfer to local facilities. Adolescent-friendly services were compromised, resulting in care challenges and disengagement from care. Clinic capacities to respond to adolescent needs were limited by funding cuts to multidisciplinary staff and resources. HCW and youth peer mentors (YPMs) demonstrated resilience, by adapting services, taking on expanded roles and leveraging available resources to support adolescent retention and access to care.

CONCLUSIONS

ALHIV are uniquely vulnerable, and adolescent-friendly services are essential to their treatment. The combined effects of the pandemic, health system changes and funding cuts compromised adolescent-friendly care and limited capacity to respond to adolescent needs. There is a need to reinforce adolescent-friendly services within programmes and funding structures. Support for expanded YPM roles may facilitate dedicated, scalable and effective adolescent-friendly services, which are resilient and sustainable in times of crisis.

Impact of COVID-19 on income, prevention attitudes, and access to healthcare among male clients in a Sexually Transmitted Infections clinic

BACKGROUND

Mobility restrictions and overloaded health services during the COVID-19 pandemic compromised services dedicated to the prevention and care of HIV and other sexually transmitted infections (STI). In this study, we present client's responses to standardized questionnaires applied during the COVID-19 pandemic period as part of the strategy to measure impacts on social and sexual vulnerability, access to STI prevention services, and access to STI care.

METHODS

The questionnaires included variables on sociodemographics, behavior, risk perception, prevention attitudes, barriers to service-based HIV rapid test, reasons for taking an HIV self-test, and access to health services for STI diagnosis and treatment. We explored demographic variables associated with income reduction, reduced access to HIV/STI testing/treatment and increased vulnerability to HIV/STI.

RESULTS

847 participants responded to the study questionnaire between May 2020 and January 2021. Most were young, cisgender male, and 63% self-reported as men who have sex with men. Income reductions were reported by 50%, with 30% reporting a decline over 50% of total income. An increase in heavy episodic drinking (>5 doses) was reported by 18%; 7% reported more sexual partners and 6% reported using condoms less often. Difficulties in obtaining HIV tests, tests for other STI and treatment for STI were reported by 5%, 6% and 6%, respectively. Lower schooling was significantly associated with income reduction (p = 0.004) and with reduced access to HIV/STI testing or STI treatment (p = 0.024); employment status was associated with income reduction (p < 0.001) and increased vulnerability to HIV/STI (p = 0.027). Having access to an expedite test result, avoiding physical attendance in health units during the pandemic, and undertaking the test with privacy with a trusted person were reported as motivators for HIV self-test.

CONCLUSIONS

Our findings are relevant to promote service improvements tailored to subgroups more likely to struggle with detrimental effects during and after the COVID-19 pandemic.
