Implementing voluntary medical male circumcision using an innovative, integrated, health systems approach: experiences from 21 districts in Zimbabwe

Estimates of the prevalence of male circumcision in sub-Saharan Africa from 2010-2023-A systematic review and meta-analysis

BACKGROUND

Male circumcision (MC) is a key part of the package of interventions to prevent HIV, the biggest health challenge in sub-Saharan Africa.

OBJECTIVE

To estimate the male circumcision prevalence and to evaluate the progress towards meeting WHO targets in sub-Saharan Africa during the period 2010-2023.

METHODS

We carried out a systematic review and meta-analysis of studies published during the period 2010-2023. We searched PubMed, Scopus, Cochrane CENTRAL, Google Scholar, WHO and the Demographic and Health Survey for reports on MC prevalence in sub-Saharan Africa. MC prevalence was synthesized using inverse-variance heterogeneity models, heterogeneity using I2 statistics and publication bias using funnel plots.

RESULTS

A total of 53 studies were included. The overall prevalence during the study period was 45.9% (95% CI 32.3-59.8), with a higher MC prevalence in Eastern (69.9%, 95%CI 49.9-86.8) compared to Southern African (33.3%, 95%CI 21.7-46.2). The overall prevalence was higher in urban (45.3%, 95%CI 27.7-63.4) compared to rural settings (42.6%, 95% 26.5-59.5). Male circumcision prevalence increased from 40.2% (95% CI 25.0-56.3) during 2010-2015 to 56.2% (95% CI 31.5-79.5) during 2016-2023. Three countries exceeded 80% MC coverage, namely, Ethiopia, Kenya and Tanzania.

CONCLUSION

Overall, the current MC prevalence is below 50%, with higher prevalence in Eastern African countries and substantially lower prevalence in Southern Africa. Most of the priority countries need to do more to scale up medical male circumcision programs.

Implementing quality management strategies improves clinical quality as a voluntary medical male circumcision program in Namibia matures: a process analysis

BACKGROUND

Surgical voluntary medical male circumcision (VMMC) is a safe procedure; however, maintaining quality standards at scale, particularly during scale-up, is a challenge making ongoing quality management (QM) efforts essential. This study describes program quality measured by rates of adverse events (AEs) over four years of VMMC implementation in Namibia, compares AE rates over time, and discusses QM processes that contextualize AE trends and illustrate improvements in quality as the program matured. The International Training and Education Center for Health (I-TECH) assisted the Namibian Ministry of Health and Social Services (MoHSS) in expanding VMMC in three regions among boys and men over 10 years of age between January 2015 and September 2019.

METHODS

A comprehensive package of QM strategies was implemented by multi-disciplinary onsite teams with support from national and international technical advisors. Retrospective routine MoHSS data from the VMMC register, client forms, and monthly AE reports were collected during implementation in the three regions to assess the impact of QM interventions on AEs and to calculate the proportion of clients who experienced AEs over time. The proportion of clients who experienced an AE over time was compared using a Cochran-Armitage test for trend.

RESULTS

Between January 2015 and September 2019, 40,336 clients underwent VMMC and 593 (1.5%) clients experienced a post-operative AE in the three supported regions. The AE rate was highest in the first quarter of clinical service delivery in each region (January-March 2015 in Oshana and Zambezi, October-December 2017 in //Kharas) but declined over the implementation period as the program matured. This observed trend between program maturity and declining AE rates over time was significant (p < 0.001) when compared using a Cochran-Armitage test for trend.

CONCLUSIONS

As the I-TECH-supported VMMC program matured, QM measures were introduced and routinized, and clinical quality improved over time with the rate of AEs decreasing significantly over the implementation period. Applying systematic and continuous QM processes and approaches across the continuum of VMMC services and considering local context can contribute to increased clinical safety. QM measures that are established in more mature program sites can be quickly adopted to respond to quality issues in program expansion sites.

Preventing HIV Among Adolescent Boys and Young Men Through PEPFAR-Supported Voluntary Medical Male Circumcision in 15 Sub-Saharan African Countries, 2018-2021

Voluntary medical male circumcision (VMMC) is an HIV prevention intervention that has predominantly targeted adolescent and young men, aged 10-24 years. In 2020, the age eligibility for VMMC shifted from 10 to 15 years of age. This report describes the VMMC client age distribution from 2018 to 2021, at the site, national, and regional levels, among 15 countries in southern and eastern Africa. Overall, in 2018 and 2019, the highest proportion of VMMCs were performed among 10-14-year-olds (45.6% and 41.2%, respectively). In 2020 and 2021, the 15-19-year age group accounted for the highest proportion (37.2% and 50.4%, respectively) of VMMCs performed across all age groups. Similarly, in 2021 at the site level, 68.1% of VMMC sites conducted the majority of circumcisions among men aged 15-24 years. This analysis highlights that adolescent boys and young men are the primary recipients of VMMC receiving an important lifetime reduction in HIV risk.

Community engagement for the Voluntary Medical Male Circumcision (VMMC) program: an analysis of key stakeholder roles to promote a sustainable program in Zambia

Background: Within the Voluntary Medical Male Circumcision (VMMC) programme, community engagement has been central in facilitating the acceptance of VMMC, especially in non-circumcising communities. We used the case of the development of community engagement plans for sustainability of VMMC in Zambia to illustrate diversity of stakeholders, their power, roles, and strategies in community engagement. Methods: Data were collected using document review, in-depth interviews (n=35) and focus group discussions (n=35) with community stakeholders, health workers, health centre committees, counsellors, teachers, community volunteers and parents/caregivers. Data were analysed using thematic analysis. The analysis was guided by the power and interest model. Results: Differences were noted between the rural and urban sites in terms of power/influence and interest rating of community stakeholders who could be involved in the sustainability phase of the VMMC response in Zambia. For example, in the urban setting, neighbourhood health committees (NHCs), health workers, leaders of clubs, community health workers (CHWs), radio, television and social media platforms were ranked highest. From this list, social media and television platforms were not highly ranked in rural areas. Some stakeholders had more sources of power than others. Forms or sources of power included technical expertise, local authority, financial resources, collective action (action through schools, churches, media platforms, other community spaces), and relational power.   Key roles and strategies included strengthening and broadening local coordination systems, enhancing community involvement, promoting community-led monitoring and evaluation, through the use of locally recognised communication spaces and channels, facilitating ownership of VMMC, and improving local accountability processes in VMMC activities. Conclusions: By consulting with the most relevant stakeholders, and considering community needs in programme development, the VMMC programme may be able to leverage the community structures and systems to reduce long term demand generation costs for VMMC and increase the acceptability and frequency of male circumcision.

Opinions on integrating couple counselling and female sexual reproductive health services into Voluntary Medical Male Circumcision services in Lilongwe, Malawi

Background

Couples HIV Counselling and Testing (CHCT) has been found to be potentially beneficial than individual HIV Counselling and Testing for prevention and treatment of HIV. However, there are few health care opportunities for men and women to access health services together, leading to underutilization of CHCT service. Integrating female Sexual and Reproductive Health (SRH) services into male-dominated service could be more effective than trying to integrate men’s health services into female-dominated health services. A potential site for male-female service integration could be Voluntary Medical Male Circumcision (VMMC) centers.

Methodology

We conducted a qualitative study in Lilongwe, Malawi between June to August 2018. Twenty VMMC clients, 20 peers and 20 VMMC providers completed individual in-depth interviews to share their opinions on what they thought about integrating CHCT and other SRH Services into VMMC services. These proposed SRH services include family planning, cervical cancer screening, sexually transmitted infection management and pre-exposure prophylaxis (PrEP). Content analysis was used to analyze the results.

Results

All participants were receptive to integration of CHCT, and most accepted the integration of SRH services into VMMC Services. Most VMMC clients, peers and care providers said that CHCT integration would help couples to know their HIV status, prevent HIV transmission, encourage healthy relationships, and provide a chance for women to participate in VMMC counselling and wound care. However, integration of other services, such as family planning and cervical cancer screening, drew mixed opinions among participants. Most VMMC clients, peers and providers felt that integration of services would promote male involvement and increase men’s knowledge in feminine sexual reproductive health services. A few providers expressed concerns over service integration, citing reasons such as overcrowding, work overload, gender mixing, and lack of provider capacity and space. Most participants supported integrating PrEP with VMMC Services and felt that PrEP would complement VMMC in HIV prevention. Few providers, peers and VMMC clients felt the addition of PrEP to VMMC services would lead to high-risk sexual activity that would then increase the risk for HIV acquisition. A few participants recommended community sensitization when integrating some of sexual reproductive health services into VMMC Services to mitigate negative perceptions about VMMC services and encourage service uptake among couples

Conclusion

Most participants service providers, VMMC clients and Peers were receptive to integrating SRH services, particularly HIV prevention services such as CHCT and PrEP, into male dominated VMMC services. Adequate community sensitization is required when introducing other SRH services into VMMC services.

REDCap mobile data collection: Using implementation science to explore the potential and pitfalls of a digital health tool in routine voluntary medical male circumcision outreach settings in Zimbabwe

Background

Digital data collection tools improve data quality but are limited by connectivity. ZAZIC, a Zimbabwean consortium focused on scaling up male circumcision (MC) services, provides MC in outreach settings where both data quality and connectivity is poor. ZAZIC implemented REDCap Mobile app for data collection among roving ZAZIC MC nurses. To inform continued scale-up or discontinuation, this paper details if, how, and for whom REDCap improved data quality using the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework.

Methods

Data were collected for this retrospective, cross-sectional study for nine months, from July 2019 to March 2020, before COVID-19 paused MC services. Data completeness was compared between paper- and REDCap-based tools and between two ZAZIC partners using two sample, one-tailed t-tests.

Results

REDCap reached all roving nurses who reported 26,904 MCs from 1773 submissions. REDCap effectiveness, as measured by data completeness, decreased from 89.2% in paper to 76.6% in REDCap app for Partner 1 (p < 0.001, 95% CI: -0.24, -0.12) but increased modestly from 86.2% to 90.3% in REDCap for Partner 2 (p = 0.05, 95% CI: -.007, 0.12). Adoption of REDCap was 100%; paper-based reporting concluded in October 2019. Implementation varied by partner and user. Maintenance appeared high.

Conclusion

Although initial transition from paper to REDCap showed mixed effectiveness, post-hoc analysis from service resumption found increased REDCap data completeness across partners, suggesting locally-led momentum for REDCap-based data collection. Staff training, consistent mentoring, and continued technical support appear critical for continued use of digital health tools for quality data collection in rural Zimbabwe and similar low connectivity settings.

Adverse Event Trends Within a Large-Scale, Routine, Voluntary Medical Male Circumcision Program in Zimbabwe, 2014-2019

BACKGROUND

Between 2008 and 2020, over 22.6 million male circumcisions (MCs) were performed among men ≥10 years in 15 priority countries of East and Southern Africa. Few studies from routine MC programs operating at scale describe trends of adverse events (AEs) or AE rates over time.

SETTING

Routine program data from a large MC program in Zimbabwe.

METHODS

χ2 compared characteristics of patients with AEs. Univariable and multivariable logistic models examined factors associated with AE severity. Cochran-Armitage trend tests compared AE rate trends by year (2014-2019), age, and MC method (2017-2019).

RESULTS

From 2014 to 2019, 469,000 men were circumcised; of the total men circumcised, 38%, 27%, and 35% were conducted among individuals aged 10-14; 15-19; and ≥20 years, respectively. Most MCs (95%) used surgical (dorsal slit or forceps-guided) methods; 5% were device based (PrePex). AEs were reported among 632 (0.13%) MCs; 0.05% were severe. From 2015 to 2019, overall AE rates declined from 34/10,000 to 5/10,000 (P-value <0.001). Severe AE rates also decreased over this period from 12/10,000 to 2/10,000 (P-value <0.001). AE rates among younger clients, aged 10-14 (18/10,000) were higher than among older age men (9/10,000) aged ≥20 years (P < 0.001); however, there was no significant association between age and AE severity.

CONCLUSION

AE rates each year and over time were lower than the World Health Organization acceptable maximum (2% AEs). ZAZIC quality assurance activities ensured guideline adherence, mentored clinicians to MC competency, promoted quality client education and counseling, and improved AE reporting over time. Decreases in AE rates are likely attributed to safety gains and increasing provider experience.

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.

Cost-effectiveness analysis of two-way texting for post-operative follow-up in Zimbabwe's voluntary medical male circumcision program

Objective

Although adverse events (AEs) following voluntary medical male circumcision (VMMC) are rare, their prompt ascertainment and management is a marker of quality care. The use of two-way text messaging (2wT) for client follow-up after VMMC reduces the need for clinic visits (standard of care (SoC)) without compromising safety. We compared the cost-effectiveness of 2wT to SoC for post-VMMC follow-up in two, high-volume, public VMMC sites in Zimbabwe.

Materials and methods

We developed a decision-analytic (decision tree) model of post-VMMC client follow-up at two high-volume sites. We parameterized the model using data from both a randomized controlled study of 2wT vs. SoC and from the routine VMMC program. The perspective of analysis was the Zimbabwe government (payer). The time horizon covered the time from VMMC to wound healing. Costs included text messaging; both in-person and outreach follow-up; and AE management. Costs were estimated in 2018 U.S. dollars. The outcome of analysis was AE yield relative to the globally accepted safety standard of a 2% AE rate. We estimated the incremental cost per percentage increase in AE ascertainment and the incremental cost per additional AE identified. We conducted univariate and probabilistic sensitivity analyses.

Results

2wT increased the costs due to text messaging by $4.42 but reduced clinic visit costs by $2.92 and outreach costs by $3.61 –a net savings of $2.10. 2wT also increased AE ascertainment by 50% (92% AE yield in 2wT compared to 42% AE yield in SoC). Therefore, 2wT dominated SoC in the incremental analysis: 2wT was less costly and more effective. Results were generally robust to univariate and probabilistic sensitivity analysis.

Conclusions

2wT is cost-effective for post-VMMC follow-up in Zimbabwe. Countries in which VMMC is a high-priority HIV prevention intervention should consider this mHealth intervention to reduce overall cost per VMMC, increasing the likelihood of current and future VMMC program sustainability.

Reducing Provider Workload While Preserving Patient Safety: A Randomized Control Trial Using 2-Way Texting for Postoperative Follow-up in Zimbabwe's Voluntary Medical Male Circumcision Program

Supplemental Digital Content is Available in the Text.

Voluntary medical male circumcisions (MCs) are safe: the majority of men heal without complication. However, guidelines require multiple follow-up visits. In Zimbabwe, where there is high mobile phone ownership, severe health care worker shortages, and rapid MC scale up intersect, we tested a 2-way texting (2wT) intervention to reduce provider workload while safeguarding patient safety.

Usability and acceptability of a two-way texting intervention for post-operative follow-up for voluntary medical male circumcision in Zimbabwe

BACKGROUND

Voluntary medical male circumcision (MC) is safe and effective. Nevertheless, MC programs require multiple post-operative visits. In Zimbabwe, a randomized control trial (RCT) found that post-operative two-way texting (2wT) between clients and MC providers instead of in-person reviews reduced provider workload and safeguarded patient safety. A critical component of the RCT assessed usability and acceptability of 2wT among providers and clients. These findings inform scale-up of the 2wT approach to post-operative follow-up.

METHODS

The RCT assigned 362 adult MC clients with cell phones into 2wT; these men responded to 13 automated daily texts supported by interactive texting or in-person follow-up, when needed. A subset of 100 texting clients filled a self-administered usability survey on day 14. 2wT acceptability was ascertained via 2wT response rates. Among 2wT providers, eight key informant interviews focused on 2wT acceptability and usability. Influences of wage and age on response rates and client-reported potential AEs were explored using linear and logistic regression models, respectively.

RESULTS

Clients felt confident, comfortable, satisfied, and well-supported with 2wT-based follow-up; few noted texting challenges or concerns about healing. Clients felt 2wT saved them time and money. Response rates (92%) suggested 2wT acceptability. Both clients and providers felt 2wT was highly usable. Providers noted 2wT saved them time, empowered clients to engage in their healing, and closed gaps in MC service quality. For scale, providers reinforced good post-operative counseling on AEs and texting instructions. Wage and age did not influence text response rates or potential AE texts.

CONCLUSION

Results strongly suggest that 2wT is highly usable and acceptable for providers and patients. Men with concerns solicited provider guidance and reassurance offered via text. Providers noted that men engaged proactively in their healing. 2wT between providers and patients should be expanded for MC and considered for other short-term care contexts. The trial is registered on ClinicalTrials.gov, trial NCT03119337, and was activated on April 18, 2017. https://clinicaltrials.gov/ct2/show/NCT03119337.

Eligibility for hepatitis B antiviral therapy among adults in the general population in Zambia

INTRODUCTION

We evaluated antiviral therapy (AVT) eligibility in a population-based sample of adults with chronic hepatitis B virus (HBV) infection in Zambia.

MATERIALS AND METHODS

Using a household survey, adults (18+ years) were tested for hepatitis B surface antigen (HBsAg). Sociodemographic correlates of HBsAg-positivity were identified with multivariable regression. HBsAg-positive individuals were referred to a central hospital for physical examination, elastography, and phlebotomy for HBV DNA, hepatitis B e antigen, serum transaminases, platelet count, and HIV-1/2 antibody. We determined the proportion of HBV monoinfected adults eligible for antiviral therapy (AVT) based on European Association for the Study of the Liver (EASL) 2017 guidelines. We also evaluated the performance of two alternative criteria developed for use in sub-Saharan Africa, the World Health Organization (WHO) and Treat-B guidelines.

RESULTS

Across 12 urban and 4 rural communities, 4,961 adults (62.9% female) were tested and 182 (3.7%) were HBsAg-positive, 80% of whom attended hospital follow-up. HBsAg-positivity was higher among men (adjusted odds ratio [AOR], 1.37; 95% confidence interval [CI], 0.99-1.87) and with decreasing income (AOR, 0.89 per household asset; 95% CI, 0.81-0.98). Trends toward higher HBsAg-positivity were also seen at ages 30-39 years (AOR, 2.11; 95% CI, 0.96-4.63) and among pregnant women (AOR, 1.74; 95% CI, 0.93-3.25). Among HBV monoinfected individuals (i.e., HIV-negative) evaluated for AVT, median age was 31 years, 24.6% were HBeAg-positive, and 27.9% had HBV DNA >2,000 IU/ml. AVT-eligibility was 17.0% by EASL, 10.2% by WHO, and 31.1% by Treat-B. Men had increased odds of eligibility. WHO (area under the receiver operating curve [AUROC], 0.68) and Treat-B criteria (AUROC, 0.76) had modest accuracy. Fourteen percent of HBsAg-positive individuals were HIV coinfection, and most coinfected individuals were taking tenofovir-containing antiretroviral therapy (ART).

CONCLUSION

Approximately 1 in 6 HBV monoinfected adults in the general population in Zambia may be AVT-eligible. Men should be a major focus of hepatitis B diagnosis and treatment. Further development and evaluation of HBV treatment criteria for resource-limited settings is needed. In settings with overlapping HIV and HBV epidemics, scale-up of ART has contributed towards hepatitis B elimination.

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.

90-90-90 by 2020? Estimation and projection of the adult HIV epidemic and ART programme in Zimbabwe - 2017 to 2020

INTRODUCTION

The 90-90-90 targets set by the United Nations aspire to 73% of people living with HIV (PLHIV) being virally suppressed by 2020. Using the HIV Synthesis Model, we aim to mimic the epidemic in Zimbabwe and make projections to assess whether Zimbabwe is on track to meet the 90-90-90 targets and assess whether recently proposed UNAIDS HIV transition metrics are likely to be met.

METHODS

We used an approximate Bayesian computation approach to identify model parameter values which result in model outputs consistent with observed data, evaluated using a calibration score. These parameter values were then used to make projections to 2020 to compare with the 90-90-90 targets and other key indicators. We also calculated HIV transition metrics proposed by UNAIDS (percentage reduction in new HIV infections and AIDS-related mortality from 2010 to 2020, absolute rate of new infections and AIDS-related mortality, incidence-mortality ratio and incidence-prevalence ratios).

RESULTS

After calibration, there was general agreement between modelled and observed data. The median predicted outcomes in 2020 were: proportion of PLHIV (aged 15 to 65) diagnosed 0.91 (90% uncertainty range 0.87, 0.94) (0.84 men, 0.95 women); of those diagnosed, proportion on treatment 0.92 (0.90, 0.93); of those receiving treatment, proportion with viral suppression 0.86 (0.81, 0.91). This results in 72% of PLHIV having viral suppression in 2020. We estimated a percentage reduction of 36.5% (13.7% increase to 67.4% reduction) in new infections from 2010 to 2020, and of 30.4% (9.7% increase to 56.6% reduction) in AIDS-related mortality (UNAIDS target 75%). The modelled absolute rates of HIV incidence and AIDS-related mortality in 2020 were 5.48 (2.26, 9.24) and 1.93 (1.31, 2.71) per 1000 person-years respectively. The modelled incidence-mortality ratio and incidence-prevalence ratios in 2020 were 1.05 (0.46, 1.66) and 0.009 (0.004, 0.013) respectively.

CONCLUSIONS

Our model was able to produce outputs that are simultaneously consistent with an array of observed data and predicted that while the 90-90-90 targets are within reach in Zimbabwe, increased efforts are required in diagnosing men in particular. Calculation of the HIV transition metrics suggest increased efforts are needed to bring the HIV epidemic under control.

Reducing provider workload while preserving patient safety via a two-way texting intervention in Zimbabwe's voluntary medical male circumcision program: study protocol for an un-blinded, prospective, non-inferiority, randomized controlled trial

Background

Surgical male circumcision (MC) safely reduces risk of female-to-male HIV-1 transmission by up to 60%. The average rate of global moderate and severe adverse events (AEs) is 0.8%: 99% of men heal from MC without incident. To reach the 2016 global MC target of 20 million, productivity must double in countries plagued by severe healthcare worker shortages like Zimbabwe. The ZAZIC consortium partners with the Zimbabwe Ministry of Health and Child Care and has performed over 120,000 MCs. MC care in Zimbabwe requires in-person, follow-up visits at post-operative days 2,7, and 42. The ZAZIC program AE rate is 0.4%; therefore, overstretched clinic have staff conducted more than 200,000 unnecessary reviews of MC clients without complications.

Methods

Through an un-blinded, prospective, randomized, controlled trial in two high-volume MC facilities, we will compare two groups of adult MC clients with cell phones, randomized 1:1 into two groups: (1) routine care (control group, N = 361) and (2) clients who receive and respond to a daily text with in-person follow up only if desired or if a complication is suspected (intervention group, N = 361). If an intervention client responds affirmatively to any automated daily text with a suspected AE, an MC nurse will exchange manual, modifiable, scripted texts with the client to determine symptoms and severity, requesting an in-person visit if desired or warranted. Both arms will complete a study-specific, day 14, in-person, follow-up review for verification of self-reports (intervention) and comparison (control). Data collection includes extraction of routine client MC records, study-specific database reports, and participant usability surveys. Intent-to-treat (ITT) analysis will be used to explore differences between groups to determine if two-way texting (2wT) can safely reduce MC follow-up visits, estimate the cost savings associated with 2wT over routine MC follow up, and assess the acceptability and feasibility of 2wT for scale up.

Discussion

It is expected that this mobile health intervention will be as safe as routine care while providing distinct advantages in efficiency, costs, and reduced healthcare worker burden. The success of this intervention could lead to adaptation and adoption of this intervention at the national level, increasing the efficiency of MC scale up, and reducing burdens on providers and patients.

Trust but verify: Is there a role for active surveillance in monitoring adverse events in Zimbabwe's large-scale male circumcision program?

Introduction

Ensuring quality service provision is fundamental to ZAZIC’s voluntary medical male circumcision (MC) program in Zimbabwe. From October, 2014 to September, 2017, ZAZIC conducted 205,847 MCs. Passive surveillance recorded a combined moderate and severe adverse event (AE) rate of 0.3%; reported adherence to follow-up was 95%, suggesting program safety. Despite encouraging passive surveillance data, verification of data quality and accuracy would increase confidence in AE identification.

Methods

From May to August, 2017, ZAZIC implemented a focused quality assurance (QA) study on AE ascertainment and documentation at 6 purposively-selected, high-volume MC sites. ZAZIC Gold-Standard (GS) clinicians prospectively observed 100 post-MC follow-ups per site in tandem with facility-based MC providers to confirm and characterize AEs, providing mentoring in AE management when needed. GS clinicians also retrospectively reviewed site-based, routine MC data, comparing recorded to reported AEs, and held brief qualitative interviews with site leadership on AE-related issues.

Results

Observed AE rates varied from 1–8%, potentially translating to thousands of unidentified AEs if observed AE rates were applied to previous MC performance. Most observed AEs were infections among younger clients. Retrospective review found discrepancies in AE documentation and reporting. Interviews suggest human resource and transport issues challenge MC follow-up visit attendance. Post-operative self-care appears to produce generally good results for adults; however, younger clients and guardians need additional attention to ensure quality care. There was no evidence of missed severe AEs resulting in permanent impairment or morbidity.

Conclusions

Although results cannot be generalized, active surveillance suggests that AEs may be higher and follow-up lower than reported. In response, ZAZIC’s Quality Assurance Task Force will replicate this QA study in other sites; increase training in AE identification, management, and documentation for clinical and data teams; and improve post-operative counseling for younger clients. Additional nurses and vehicles, especially in rural health clinics, could be beneficial.

Incorporating Voluntary Medical Male Circumcision Into Traditional Circumcision Contexts: Experiences of a Local Consortium in Zimbabwe Collaborating With an Ethnic Group

Employing voluntary medical male circumcision (VMMC) within traditional settings may increase patient safety and help scale up male circumcision efforts in sub-Saharan Africa. In Zimbabwe, the VaRemba are among the few ethnic groups that practice traditional male circumcision, often in suboptimal hygienic environments. ZAZIC, a local consortium, and the Zimbabwe Ministry of Health and Child Care (MoHCC) established a successful, culturally sensitive partnership with the VaRemba to provide safe, standardized male circumcision procedures and reduce adverse events (AEs) during traditional male circumcision initiation camps. The foundation for the VaRemba Camp Collaborative (VCC) was established over a 4-year period, between 2013 and 2017, with support from a wide group of stakeholders. Initially, ZAZIC supported VaRemba traditional male circumcisions by providing key commodities and transport to help ensure patient safety. Subsequently, 2 male VaRemba nurses were trained in VMMC according to national MoHCC guidelines to enable medical male circumcision within the camp. To increase awareness and uptake of VMMC at the upcoming August-September 2017 camp, ZAZIC then worked closely with a trained team of circumcised VaRemba men to create demand for VMMC. Non-VaRemba ZAZIC doctors were granted permission by VaRemba leaders to provide oversight of VMMC procedures and postoperative treatment for all moderate and severe AEs within the camp setting. Of 672 male camp residents ages 10 and older, 657 (98%) chose VMMC. Only 3 (0.5%) moderate infections occurred among VMMC clients; all were promptly treated and healed well. Although the successful collaboration required many years of investment to build trust with community leaders and members, it ultimately resulted in a successful model that paired traditional circumcision practices with modern VMMC, suggesting potential for replicability in other similar sub-Saharan African communities.

Timing of adverse events among voluntary medical male circumcision clients: Implications from routine service delivery in Zimbabwe

BACKGROUND

Timing of routine follow-up visits after adult male circumcision (MC) differs by country and method. Most men do not attend all routine follow-up visits. This cross-sectional study aimed to further understanding of AE timing within a large-scale, routine, MC program to improve patient safety.

METHODS

From 2013-2017, ZAZIC consortium performed 192,575 MCs in Zimbabwe; the reported adverse event (AE) rate was 0.3%. Three scheduled, routine, follow-up visits intend to identify AEs. For surgical MC, visits were days 2, 7 and 42 post-procedure. For PrePex (device-based), visits were days 7, 14 and 49. Descriptive statistics explored characteristics of those patients with AEs. For each MC method, chi-square tests were used to evaluate associations between AE timing (days from MC to AE diagnosis) and factors of interest (age, AE type, severity).

RESULTS

Of 421 AEs, 290 (69%) were surgical clients: 55 (19%) AEs were ≤2 days post-MC; 169 (58%) between 3-7 days; 47 (16%) between days 8-14; and 19 (7%) were ≥15 post-MC. Among surgical clients, bleeding was most common AE on/before Day 2 while infections predominated in other follow-up periods (p<0.001). Younger surgical MC patients with AEs experienced AEs later than older clients (p<0.001). Among 131 (31%) PrePex clients with AEs, 46 (35%) were ≤2 days post-MC; 59 (45%) between 3-7 days; 16 (12%) between days 8-14; and 10 (7%) ≥15 post-MC. For PrePex clients, device displacements were more likely to occur early while late AEs were most commonly infections (p<0.001).

CONCLUSION

Almost 23% of surgical and 8% of PrePex AEs occurred after Visit 2. Later AEs were likely infections. Clinicians, clients, and caregivers should be more effectively counseled that complications may arise after initial visits. Messages emphasizing attention to wound care until complete healing could help ensure client safety. Younger boys, ages 10-14, and their caregivers would benefit from improved, targeted, post-operative counseling.

Systematic review of barriers and facilitators to voluntary medical male circumcision in priority countries and programmatic implications for service uptake

Voluntary medical male circumcision (VMMC) is an effective biomedical HIV prevention strategy. There is a need to identify key barriers and facilitators to VMMC uptake in priority countries to improve uptake. In this paper, we report findings from a systematic review of the barriers and facilitators of VMMC uptake, comparing them across countries in order to provide programmers critical information to design effective VMMC uptake interventions. Our review followed PRISMA protocol. Twenty three articles from 10 of the 14 priority countries were included. The top three barriers cited were: MC negatively perceived as being practiced by other or foreign cultures and religions, fear of pain caused by the procedure, and perceptions of VMMC as not helpful/needed. The top four facilitators cited in most countries were: Belief that VMMC reduces health risks and improves hygiene, family and peer support of MC, and enhanced sexual performance and satisfaction. The barriers and facilitators highlighted in this paper can help inform programmatic strategies in these countries. More research is needed to ensure that all sub-populations are being adequately reached. By applying this information to new research and programming, these countries can achieve greater VMMC uptake - and thus reductions in HIV transmission and prevalence.
