Consent Challenges and Psychosocial Distress in the Scale-up of Voluntary Medical Male Circumcision Among Adolescents in Western Kenya

Ethics of Mathematical Modeling in Public Health: The Case of Medical Male Circumcision for HIV Prevention in Africa

Mathematical modelling has played an increasingly prominent role in public health responses, for example by offering estimates of how infectious disease incidence over time may be affected by the adoption of certain policies and interventions. In this paper, we call for greater research and reflection into the ethics of mathematical modeling in public health. First, we present some promising ways of framing the ethics of mathematical modeling that have been offered in the very few publications specifically devoted to this subject. Second, to draw out some issues that have not yet been sufficiently considered, we bring in the case of mathematical modeling in voluntary medical male circumcision (VMMC) initiatives for HIV prevention in Africa. We argue that greater attention should be paid to ethical considerations in mathematical modeling, particularly as its use is becoming more widespread and its potential impacts are becoming greater in the 'big data' era, as witnessed during the COVID-19 pandemic.

A review of public health, social and ethical implications of voluntary medical male circumcision programs for HIV prevention in sub-Saharan Africa

Ideally, the benefits of public health interventions should outweigh any associated harms, burdens, and adverse unintended consequences. The intended benefit of voluntary medical male circumcision (VMMC) programs in eastern and southern Africa (ESA) is the reduction of HIV infections. We review the literature for evidence of reductions in HIV incidence, evaluate the extent to which decreases in HIV incidence can be reasonably attributed to VMMC programs, and summarize social harms and ethical concerns associated with these programs. Review findings suggest that HIV incidence had been declining across ESA since before the large-scale rollout of VMMC as a public health intervention, and that this decline may be due to the combined effects of HIV prevention and treatment interventions, such as expanded antiretroviral therapy. The independent effect of VMMC programs in reducing HIV infections at the population level remains unknown. On the other hand, VMMC-associated evidence is increasing for the existence of negative social impacts such as stigmatization and/or discrimination, and ethically problematic practices, including lack of informed consent. We conclude that the relationship between the benefits and burdens of VMMC programs may be more unfavorable than what has been commonly suggested by proponents of global VMMC campaigns.

Effects of Comfort-Oriented Nursing Care Based on the Comfort Theory on Perioperative Anxiety and Fear in Children Undergoing Surgical Circumcision: RCT

PURPOSE

This study explored the effect of comfort-oriented nursing care based on comfort theory on reducing perioperative anxiety and fear in children undergoing surgical circumcision.

DESIGN

Randomized controlled trial.

METHOD

The study was completed with the participation of children circumcised in a hospital in Turkey using the same surgeon, anesthesia, and surgical technique. A total of 120 children meeting the inclusion criteria and providing consent to participate in the study were randomly divided into two equal groups. The study was conducted between June and September 2019. The intervention group received comfort-oriented nursing care based on the comfort theory. The control group received routine nursing care. Data were collected using the Children's Anxiety Meter-State and Children's Fear Scale. Outcome variables were determined at seven measurement points, including baseline, five intermediate points, and at the follow-up visit on the 10th postoperative day.

RESULTS

A statistically significant difference in the fear of the group receiving comfort-oriented nursing care based on comfort theory was noted compared with the control group.

CONCLUSION

Comfort-oriented nursing care based on the comfort theory was effective in reducing perioperative anxiety and fear among children undergoing surgical circumcision. This study is important given that comfort-oriented nursing care based on the comfort theory may be applied to those receiving care in pediatric surgery.

Voluntary Medical Male Circumcision for HIV Prevention: a Global Overview

PURPOSE OF REVIEW

With the promise of HIV prevention, there has been a scale-up of voluntary medical male circumcision (VMMC) in high HIV incidence/low circumcision prevalence nations worldwide. Nonetheless, debates over the implementation and the effectiveness and safety of the VMMC in real-world settings persist. We revisit the role of VMMC in HIV prevention to inform health professionals, policymakers, and advocates or opponents in this new era.

RECENT FINDINGS

There has been substantial progress on VMMC scale-up to date, but this has varied considerably by region. The evidence of solid and direct protection of VMMC is available for heterosexual men and older adolescent boys in sub-Saharan Africa. The protective effect in men who have sex with men is suggested by systematic reviews but is not confirmed by clinical trials. Sexual partners, including women, likely benefit indirectly from the increased VMMC coverage through a decreased risk of exposure to infected male partners. Fortunately, the preponderance of studies does not suggest higher sexual risk behaviors among circumcised men, so-called risk compensation. VMMC requires health systems strengthening and continued promulgation of other evidence-based HIV prevention strategies to be successful. Health authorities in high HIV incidence areas that have low circumcision coverage should implement VMMC within a context of complementary biomedical and behavioral prevention strategies.

VMMC Programmatic Successes and Challenges: Western Kenya Case Study

PURPOSE OF REVIEW

The Nyanza region of western Kenya is lauded for impressive coverage of voluntary medical male circumcision (VMMC) and remains the bedrock of the VMMC program in Kenya. We conducted literature review on programmatic successes and challenges of implementing VMMC program in the region.

RECENT FINDINGS

Responsive stakeholders' engagement, robust policy environment, effective technical working groups, prompt capacity building of health facilities, government support, flexible implementation strategies, and sustained donor funding contributed to the successes of the program that saw circumcision prevalence in Nyanza reach between 75.6 and 85.3% among 15-29-year-olds by 2019. However, the lack of support for early infant circumcision, inadequate domestic financing, and slow pace of service integration into government health facilities continue to undermine the progress towards sustainability. While local ownership of the VMMC program has been demonstrated through its inclusion in county annual health workplans and progressive integration into routine health care, continued dependence on declining external funding threatens its sustainability. Furthermore, Kenya is experiencing a youth bulge with a projected high demand for VMMC which calls for increased resource inputs into the program. Strategies are therefore needed to increase domestic resource inflows into VMMC.

Genital Cutting as Gender Oppression: Time to Revisit the WHO Paradigm

The World Health Organization (WHO) condemns all medically unnecessary female genital cutting (FGC) that is primarily associated with people of color and the Global South, claiming that such FGC violates the human right to bodily integrity regardless of harm-level, degree of medicalization, or consent. However, the WHO does not condemn medically unnecessary FGC that is primarily associated with Western culture, such as elective labiaplasty or genital piercing, even when performed by non-medical practitioners (e.g., body artists) or on adolescent girls. Nor does it campaign against any form of medically unnecessary intersex genital cutting (IGC) or male genital cutting (MGC), including forms that are non-consensual or comparably harmful to some types of FGC. These and other apparent inconsistencies risk undermining the perceived authority of the WHO to pronounce on human rights. This paper considers whether the WHO could justify its selective condemnation of non-Western-associated FGC by appealing to the distinctive role of such practices in upholding patriarchal gender systems and furthering sex-based discrimination against women and girls. The paper argues that such a justification would not succeed. To the contrary, dismantling patriarchal power structures and reducing sex-based discrimination in FGC-practicing societies requires principled opposition to medically unnecessary, non-consensual genital cutting of all vulnerable persons, including insufficiently autonomous children, irrespective of their sex traits or socially assigned gender. This conclusion is based, in part, on an assessment of the overlapping and often mutually reinforcing roles of different types of child genital cutting—FGC, MGC, and IGC—in reproducing oppressive gender systems. These systems, in turn, tend to subordinate women and girls as well as non-dominant males and sexual and gender minorities. The selective efforts of the WHO to eliminate only non-Western-associated FGC exposes the organization to credible accusations of racism and cultural imperialism and paradoxically undermines its own stated goals: namely, securing the long-term interests and equal rights of women and girls in FGC-practicing societies.

Social complexities of informed consent and assent among young males undergoing voluntary medical male circumcision in Eswatini

INTRODUCTION

As part of an effort to meet ambitious male circumcision targets in Eswatini, programme implementers have increasingly focused on young males, raising questions about informed consent. Males aged 10-19 years account for more than two-thirds of those circumcised since 2008 when internationally funded circumcision campaigns began in Eswatini. The ethical guidelines of these programmes conform to international standards, requiring that informed consent or assent be obtained prior to surgery. This article examines clients' levels of circumcision-related knowledge following the assent process, as well as how ethical guidelines were enacted in everyday practice in a setting where family dynamics and norms relating to autonomy and consensus make obtaining informed consent complex, especially when clients are incentivised with football kits and other material goods to encourage circumcision.

METHODS

We conducted qualitative research in a health clinic where circumcision services for HIV prevention were being offered. Methods included focus group discussions, in-depth interviews, participant observation and informal interviews with young men undergoing circumcision in the clinic.

RESULTS

Implementers paid little attention to risks, focusing more on benefits of circumcision. Incentives, usually in the form of sporting goods, increased participation, while also limiting autonomy. We also found that parental authority overpowers young males' preferences regarding circumcision. Young males' understanding of the risks associated with circumcision was poor. Most assumed HIV testing was obligatory.

CONCLUSION

The drive to eliminate HIV infections in Eswatini has opened the door for interventions such as targeted circumcision campaigns. In contradiction to international ethical guidelines and the policies of the Ministry of Health and voluntary medical male circumcision (VMMC) implementers, we conclude that, in practce, respect for young males' rights and decision-making in the VMMC consent process is limited by complex social, economic and political realities.

Intervening for HIV prevention and mental health: a review of global literature

INTRODUCTION

Numerous effective HIV prevention options exist, including behaviour change interventions, condom promotion and biomedical interventions, like voluntary medical male circumcision and pre-exposure prophylaxis. However, populations at risk of HIV also face overlapping vulnerabilities to common mental disorders and severe mental illness. Mental health status can affect engagement in HIV risk behaviours and HIV prevention programmes. We conducted a narrative review of the literature on HIV prevention among key populations and other groups vulnerable to HIV infection to understand the relationship between mental health conditions and HIV prevention outcomes and summarize existing evidence on integrated approaches to HIV prevention and mental healthcare.

METHODS

We searched five databases for studies published from January 2015 to August 2020, focused on HIV prevention and mental health conditions among key populations and individuals with serious mental illness. Studies were included if they evaluated an HIV prevention intervention or assessed correlates of HIV risk reduction and included assessment of mental health conditions or a mental health intervention.

RESULTS AND DISCUSSION

We identified 50 studies meeting our inclusion criteria, of which 26 were randomized controlled trials or other experimental designs of an HIV prevention intervention with or without a mental health component. Behaviour change interventions were the most common HIV prevention approach. A majority of studies recruited men who have sex with men and adolescents. Two studies provided distinct approaches to integrated HIV prevention and mental health service delivery. Overall, a majority of included studies showed that symptoms of mental disorder or distress are associated with HIV prevention outcomes (e.g. increased risky sexual behaviour, poor engagement in HIV prevention behaviours). In addition, several studies conducted among groups at high risk of poor mental health found that integrating a mental health component into a behaviour change intervention or linking mental health services to combination prevention activities significantly reduced risk behaviour and mental distress and improved access to mental healthcare.

CONCLUSIONS

Evidence suggests that mental health conditions are associated with poorer HIV prevention outcomes, and tailored integrated approaches are urgently needed to address overlapping vulnerabilities among key populations and other individuals at risk.

The Ethics of Stigma in Medical Male Circumcision Initiatives Involving Adolescents in Sub-Saharan Africa

Ongoing global efforts to circumcise adolescent and adult males to reduce their risk of acquiring HIV constitute the largest public health prevention initiative, using surgical means, in human history. Voluntary medical male circumcision (VMMC) programs in Africa have significantly altered social norms related to male circumcision among previously non-circumcising groups and groups that have practiced traditional (non-medical) circumcision. One consequence of this change is the stigmatization of males who, for whatever reason, remain uncircumcised. This paper discusses the ethics of stigma with regard to uncircumcised adolescent males in global VMMC programs, particularly in certain recruitment, demand creation and social norm interventions. Grounded in our own experiences gained while conducting HIV-related ethics research with adolescents in Kenya, we argue that use of explicit or implicit stigma to increase the number of VMMC volunteers is unethical from a public health ethics perspective, particularly in campaigns that leverage social norms of masculinity.

Ethics of pursuing targets in public health: the case of voluntary medical male circumcision for HIV-prevention programs in Kenya

The use of targets to direct public health programmes, particularly in global initiatives, has become widely accepted and commonplace. This paper is an ethical analysis of the utilisation of targets in global public health using our fieldwork on and experiences with voluntary medical male circumcision (VMMC) initiatives in Kenya. Among the many countries involved in VMMC for HIV prevention, Kenya is considered a success story, its programmes having medically circumcised nearly 2 million men since 2007. We describe ethically problematic practices in Kenyan VMMC programmes revealed by our fieldwork, how the problems are related to the pursuit of targets and discuss possible approaches to their management. Although the establishment and pursuit of targets in public health can have many benefits, assessments of target-driven programmes tend to focus on quantifiable outcomes rather than the processes by which the outcomes are obtained. However, in order to speak more robustly about programmatic 'success', and to maintain community trust, it is vital to ethically evaluate how a public health initiative is actually implemented in the pursuit of its targets.

Balancing competing priorities: Quantity versus quality within a routine, voluntary medical male circumcision program operating at scale in Zimbabwe

Background

Since 2013, the ZAZIC consortium supported the Zimbabwe Ministry of Health and Child Care (MOHCC) to implement a high quality, integrated voluntary medical male circumcision (VMMC) program in 13 districts. With the aim of significantly lowering global HIV rates, prevention programs like VMMC make every effort to achieve ambitious targets at an increasingly reduced cost. This has the potential to threaten VMMC program quality. Two measures of program quality are follow-up and adverse event (AE) rates. To inform further VMMC program improvement, ZAZIC conducted a quality assurance (QA) activity to assess if pressure to do more with less influenced program quality.

Methods

Key informant interviews (KIIs) were conducted at 9 sites with 7 site-based VMMC program officers and 9 ZAZIC roving team members. Confidentiality was ensured to encourage candid conversation on adherence to VMMC standards, methods to increase productivity, challenges to target achievement, and suggestions for program modification. Interviews were recorded, transcribed and analyzed using Atlas.ti 6.

Results

VMMC teams work long hours in diverse community settings to reach ambitious targets. Rotating, large teams of trained VMMC providers ensures meeting demand. Service providers prioritize VMMC safety procedures and implement additional QA measures to prevent AEs among all clients, especially minors. However, KIs noted three areas where pressure for increased numbers of clients diminished adherence to VMMC safety standards. For pre- and post-operative counselling, MC teams may combine individual and group sessions to reach more people, potentially reducing client understanding of critical wound care instructions. Second, key infection control practices may be compromised (handwashing, scrubbing techniques, and preoperative client preparation) to speed MC procedures. Lastly, pressure for client numbers may reduce prioritization of patient follow-up, while client-perceived stigma may reduce care-seeking. Although AEs appear well managed, delays in AE identification and lack of consistent AE reporting compromise program quality.

Conclusion

In pursuit of ambitious targets, healthcare workers may compromise quality of MC services. Although risk to patients may appear minimal, careful consideration of the realities and risks of ambitious target setting by donors, ministries, and implementing partners could help to ensure that client safety and program quality is consistently prioritized over productivity.

Ethical considerations for epidemic vaccine trials

Vaccines are a powerful measure to protect the health of individuals and to combat outbreaks such as the COVID-19 pandemic. An ethical dilemma arises when one effective vaccine has been successfully developed against an epidemic disease and researchers seek to test the efficacy of another vaccine for the same pathogen in clinical trials involving human subjects. On the one hand, there are compelling reasons why it would be unethical to trial a novel vaccine when an effective product exists already. First, it is a firm principle of medical ethics that an effective treatment or vaccine should not be withheld from patients if their life may depend on it. Second, since epidemic outbreaks often emerge in settings with less-resourced health systems, there is a pronounced risk that any trial withholding an effective vaccine would disproportionately affect the vulnerable populations that historically have been exploited for biomedical research. Third, clinical trials for novel vaccines may be at odds with efforts to control active outbreaks. On the other hand, it may be justified to conduct a trial for a candidate vaccine if it is expected to have certain advantages compared with the existing product. This essay discusses key factors for comparing vaccines against epidemic pathogens, including immunological, logistical and economic considerations. Alongside a case study of the development of vaccines for Ebola, the essay seeks to establish a general framework that should be expanded and populated by immunologists, epidemiologists, economists and bioethicists, and ultimately could be applied to the case of COVID-19 vaccines.

Voluntary medical male circumcision for HIV prevention among adolescents in Kenya: Unintended consequences of pursuing service-delivery targets

Introduction

Voluntary medical male circumcision (VMMC) provides significant reductions in the risk of female-to-male HIV transmission. Since 2007, VMMC has been a key component of the United States President’s Emergency Plan for AIDS Relief’s (PEPFAR) strategy to mitigate the HIV epidemic in countries with high HIV prevalence and low circumcision rates. To ensure intended effects, PEPFAR sets ambitious annual circumcision targets and provides funding to implementation partners to deliver local VMMC services. In Kenya to date, 1.9 million males have been circumcised; in 2017, 60% of circumcisions were among 10-14-year-olds. We conducted a qualitative field study to learn more about VMMC program implementation in Kenya.

Methods and results

The study setting was a region in Kenya with high HIV prevalence and low male circumcision rates. From March 2017 through April 2018, we carried out in-depth interviews with 29 VMMC stakeholders, including “mobilizers”, HIV counselors, clinical providers, schoolteachers, and policy professionals. Additionally, we undertook observation sessions at 14 VMMC clinics while services were provided and observed mobilization activities at 13 community venues including, two schools, four public marketplaces, two fishing villages, and five inland villages. Analysis of interview transcripts and observation field notes revealed multiple unintended consequences linked to the pursuit of targets. Ebbs and flows in the availability of school-age youths together with the drive to meet targets may result in increased burdens on clinics, long waits for care, potentially misleading mobilization practices, and deviations from the standard of care.

Conclusion

Our findings indicate shortcomings in the quality of procedures in VMMC programs in a low-resource setting, and more importantly, that the pursuit of ambitious public health targets may lead to compromised service delivery and protocol adherence. There is a need to develop improved or alternative systems to balance the goal of increasing service uptake with the responsible conduct of VMMC.
