Voluntary medical male circumcision (VMMC) safely reduces the risk of female-to-male HIV transmission by up to 60%. Few men have any post-operative VMMC complication. However, current practice in Zimbabwe and throughout most of sub-Saharan Africa requires VMMC patients to return for multiple, in-person post-operative visits. With low complication rates, and severe healthcare worker shortages, these required visits are a burden for providers and patients — threatening achievement of critical HIV prevention targets. A two-way texting model studied by University of Washington researchers in Zimbabwe offers a new way to address this barrier by reducing provider workload while also safeguarding patient safety.
“These visits can be a barrier to male circumcision uptake and expansion in countries with severe health care worker shortages, as well as negatively impacting patients who needlessly pay for transport, miss work, and wait for unnecessary reviews,” said Principal Investigator Caryl Feldacker, PhD, MPH, at the International Training and Education Center for Health (I-TECH) in the University of Washington Department of Global Health.
The study included 721 VMMC patients in two locations in urban Zimbabwe. In the study, patients communicated directly with a health care worker through interactive text messaging for the critical 13 days post-VMMC, rather than returning for required in-person visits. By giving men the option to heal safely at home, or return to care when desired or if complications arose, the method dramatically reduced in-person visits by 85%. Texting also reduced follow-up costs by about one-third while improving the quality of care.
As compared to routine in-person care, the study yielded twice the number of reported complications. “This increased identification and reporting is a positive result that is likely attributable to improved counseling and men’s engagement in care. Through texting, men were empowered to observe their healing and report potential issues promptly, before they worsened,” said Feldacker.
Currently, most text-based health care efforts blast pre-defined messages to many people simultaneously, removing patients’ ability to communicate back with health care workers. In contrast, two-way texting between providers and patients provides interactive care, and the short time frame heightened participation: in the study, 93% of men responded to texts. Both providers and clients reported confidence in the texting option, feeling safe and highly recommending it for scale.
“With the current system, Zimbabwe could perform millions of unnecessary follow-up visits over the coming five years. The workload burden for health care workers and time lost for patients who are healing without complication is a significant burden for health care workers and clients alike,” said Feldacker. “Potential gains in efficiency and reduced costs through using two-way messaging are large.”
With funding from the U.S. Centers for Disease Control and Prevention (CDC), and in partnership with the Society for Family Health, the model will soon be tested in urban South Africa. The new, field-based research will further test two-way texting in a different geographical and patient context to better inform the model for adaptation and widespread scale-up.
Feldacker added that “while our findings are grounded in studies on male circumcision, our results are largely attributable to the methods rather than to a specific disease or condition.
“With minimal adaptation,” she continued, “two-way texting could streamline other post-operative care contexts or be re-configured for other similarly acute, episodic conditions where continuity of care within a short period is critical for patients, such as short-course TB treatment, post-operative healing, post-natal care or early childhood illnesses — diarrhea, pneumonia, malaria — laying the foundation for generalizing to other diseases and contexts.”

The study was led by Caryl Feldacker, and co-investigators are Vernon Murenje (International Training and Education Center for Health (I-TECH), Harare, Zimbabwe); Mufuta Tshimanga (Zimbabwe Community Health Intervention Project (ZiCHIRE), Harare, Zimbabwe); Scott Barnhart, Isaac Holeman, and Joseph B. Babigumira (Department of Global Health, University of Washington); Sinokuthemba Xaba (Ministry of Health and Child Care, Harare, Zimbabwe); and technology partner Medic Mobile (Nairobi, Kenya).
The Zimbabwe 2wT study was supported by the Fogarty International Center of the National Institutes of Health under Award Number R21TW010583.
I-TECH began the expansion of cervical cancer screening for women living with HIV aged 25-49 in Zimbabwe in 2019. I-TECH initially identified a provisional list of 89 sites for the implementation of visual inspection with acetic acid and cerviography (VIAC). The team then recruited, trained, and deployed dedicated VIAC nurses to 29 sites. Additionally, in an effort to improve service coverage in hard to reach areas without the necessary equipment, district teams carry VIAC equipment to outreach point facilities who have booked client appointments in advance. Random samples of images from clients are anonymized and sent to a gynecologist from the University of Zimbabwe for quality assurance.
Across all facilities, 9,664 HIV-positive women aged 25-49 years have been screened for cervical cancer with 93% testing negative, 6% testing positive for lesions, and 1% having suspected cancer.
Last Saturday, 1 December 2018, marked the 30th World AIDS Day, with a focus on urging all people to know their HIV status, as well as on ensuring access to prevention, care, and treatment services for those affected by the disease. Two programs at the International Training and Education Center for Health (I-TECH) are working in concert with local partners to help make those goals a reality in Zimbabwe.
A center in the University of Washington (UW) Department of Global Health, I-TECH has worked in Zimbabwe since 2003, starting with a $150,000 grant for an assessment of the need for HIV training in the country. Since then, work in the country has expanded to two awards totaling more than $24 million for the current year—one of which focuses on HIV testing, care, and treatment and the other on voluntary medical male circumcision (VMMC) for HIV prevention. Both projects are funded by the U.S. Centers for Disease Control and Prevention, through the President’s Emergency Plan for AIDS Relief (PEPFAR), and operate through consortia comprising I-TECH and local partners.
The consortium for the VMMC award, ZAZIC, will continue to be led by Dr. Scott Barnhart, Professor in the UW Department of Global Health and School of Medicine. However, the consortium for the care and treatment award, the Zimbabwe Partnership to Accelerate AIDS Control (ZimPAAC), has undergone a change in leadership: its new Principal Investigator (PI) is Dr. Stefan Wiktor, Professor in the UW Department of Global Health. Dr. Wiktor was handed the baton by the project’s previous Principal Investigator, Dr. Ann Downer, I-TECH Executive Director and also a Professor in the department, during a ceremony in Harare in October 2018.
“We are all so grateful to Dr. Downer for the past five years; for gently, but firmly leading us through the transition from a training and mentoring grant to a high-impact service delivery grant in five provinces,” said Dr. Batsi Makunike, I-TECH Zimbabwe Country Director. “Looking ahead, we welcome Dr. Wiktor to our team and the opportunity to tap into the wealth of experience that he brings as our new PI.”
Dr. Wiktor expressed hope that, through the continued hard work of the Zimbabwe consortium, the country will achieve its national and global targets. “Zimbabwe is one of the countries in Africa closest to reaching the UNAIDS 95-95-95 targets, and ZimPAAC is a critical partner to the Ministry of Health in that effort,” said Dr. Wiktor. “I am delighted to be working with such an outstanding team of public health professionals.”
Through ZimPAAC, I-TECH provides direct service delivery and site support for care and treatment at 372 public sector health facilities to strengthen health systems and improve the quality of care and treatment services and increase enrollment, initiation and adherence.
The VMMC project has already performed 313,267 VMMCs, as of October 2018, surpassing PEPFAR targets. The new award aims to circumcise 500,000 men over five years, resulting in the prevention of approximately 100,000 new cases of HIV.
“It has been such a privilege to work in Zimbabwe, a country that has a real chance to control the AIDS epidemic—both because of generous funding from PEPFAR and, more importantly, because of the caliber of the Zimbabwean people who live and work here,” said Dr. Downer at the handover ceremony.
“Our Zimbabwe team, consisting of both Harare- and Seattle-based members, is one of the finest I’ve ever worked with,” she continued. “Dr. Wiktor inherits a highly productive consortium that is partnering with ZAZIC and the Ministry of Health to propel Zimbabwe toward a healthier future and an AIDS-free generation.”
The International AIDS Society (IAS) held their 22nd international AIDS conference (AIDS 2018) in Amsterdam 23-27 July 2018. This year, the conference objectives focused on advancing knowledge of HIV through research findings, promoting evidence-based HIV responses tailored to key populations, activating and galvanizing political commitment and accountability, addressing gaps in and highlighting the critical role of HIV prevention, as well as spotlighting the epidemic and HIV response in Eastern Europe and Central Asia.
Representatives from I-TECH were at the conference to present and discuss their posters:
In addition to the two presentations above, I-TECH staff and faculty had a number of other abstracts accepted to the conference:
Scott Barnhart, MD, MPH, has an extensive background as Professor of Global Health and former Director of Global Health Programs for I-TECH at the University of Washington. He has had responsibility for leading nine country offices, projects in 14 countries, and more than 500 staff. This experience and training has included extensive clinical work, research and program management in pulmonary and environmental and occupational medicine, and more than eight years as Medical Director of a safety net/Level 1 Trauma Center hospital.
Ensuring health systems can quickly detect and respond to emerging health threats is a critical challenge in both domestic and global health. Dr. Barnhart’s major implementation projects include scale-up of voluntary medical male circumcision (VMMC) in Zimbabwe and Malawi, OpenMRS, and laboratory information systems. Dr. Barnhart deploys his expertise in multiple African countries and Haiti to strengthen health systems and health care.
A goal of Dr. Barnhart’s work is to promote country-led, country owned sustainable development. Consistent with the principles of the Paris Declaration, the goal is to transition the bulk of development work and the associated leadership, ownership, technical direction and control of funding into the countries where development occurs. This approach ensures that the entire continuum of skills necessary for development (technical expertise, administration (human resources, operations, and management and accountability for funds) is transitioned to local partners. A key indicator is to have 75% or more of a grant’s funding expended in-country on local programs and local citizens and to support the local economies in these highly resourced constrained countries. Dr. Barnhart has worked closely to advance this model through projects in Haiti with a goal to shift the majority of a project to a local organization and in Zimbabwe where the VMMC program is largely run through local partners.
On April 6, the International Training and Education Center for Health (I-TECH) headed to the 8th Annual Consortium of Universities for Global Health (CUGH) Conference in Washington, D.C. I-TECH Zimbabwe presented among many colleagues in the University of Washington’s Department of Global Health, including staff of the department’s E-Learning Program (eDGH), which has worked closely with I-TECH on a number of e-learning and blended learning training programs.
This year’s conference theme was “Healthy People, Healthy Ecosystems: Implementation, Leadership & Sustainability in Global Health,” and I-TECH’s entries highlighted its sustainable workforce development work worldwide.
I-TECH Zimbabwe’s Vivian Bertman shared results on the use of text messaging as a low-cost, sustainable platform for building health care worker skills and knowledge to care for children and adolescents with HIV.
The research, titled “Health Worker Text Messaging for Training Peer Support, and Mentoring in Pediatric and Adolescent HIV/AIDS Care: Lessons Learned in Zimbabwe,” assessed the use of WhatsApp in a blended learning program. Participants used the app for peer-to-peer learning and support, generating over 300 entries, continuing discussions after course completion, and creating spin-off groups, including a support group for teens.
Highlighting the flexibility of cost-effective e-learning approaches was an oral presentation by eDGH’s Leslie Wall and Anya Nartker titled “No internet? No problem! Creative approaches to cost-effective e-learning delivery in resource-constrained settings.” The research looked at five tablet-based training programs developed by eDGH, in partnership with I-TECH, and delivered in Namibia, Tanzania, and Zimbabwe.
For participants, time spent off the job decreased from four days to less than one day, and within training programs that used text messaging to keep learners engaged, all participants finished in the time allotted. The team plans to expand learning activities and incorporate additional real-time interactions via text-message-based discussion groups or added face-to-face interactions.
Caitlin O’Brien-Carelli, an MPH graduate from the UW Global Health program, explored additional sustainable training models. O’Brien-Carelli presented her MPH thesis work on behalf of I-TECH: “Training Healthcare Workers on the Use of Electronic Medical Records in HIV Clinics in Kenya: An Evaluation of Three Training Models.”
During I-TECH Kenya’s first years of training health care workers to use the KenyaEMR system, the team adjusted its training from 5 days to 3 days, and moved the training from off-site to on-site, to increase sustainability and maintain effectiveness. Results confirmed that with the adjustments, training quality was maintained, more people in more facilities were trained, and costs were reduced significantly.
Detailing innovations on the operations front, I-TECH HQ Managing Director Rob Lindsley presented at a conference satellite session titled “Global Operations 2017: Tools for Faculty & Administrative Leaders.” Lindsley’s presentation, “It’s About How Hard You Can Get Hit and Keep Moving Forward: Global Support and PLC Registration in India,” outlined I-TECH’s complicated, creative pathway to country office registration in India.
In Zimbabwe, health care workers often need to build confidence and skills in caring for HIV-positive infants and children. The International Training and Education Center for Health (I-TECH) has employed an innovative approach to support these front-line staff – a case-based, self-study PMTCT Client Retention training.
During the introductory session, participants are oriented to the course, given self-study tips, loaned tablets and instructed on their use, and given a pre-course assessment. Participants also attend a half-day classroom session at the beginning and end of the five-week course.
A WhatsApp discussion group is also set up to send messages of motivation and reminders and for participants to share issues during the course. WhatsApp is widely used in Zimbabwe as an inexpensive mobile phone platform to message individuals and groups.
WhatsApp for collaborative problem solving
Elizabeth is a primary care nurse who was among a cohort of 30 participants in one of these trainings, conducted in Mashonaland Central Province. About one week into the course, Elizabeth faced a situation at work where she was confused about how to apply national guidelines to one of her pediatric patient cases. Elizabeth chose to bring the issue to her training cohort. Below is a sample of the discussion that ensued among several members of the group, showing that a number of the cohort were similarly perplexed:
Elizabeth: A woman came to our clinic. She was ill. She wanted to get tested because she was ill for a long time on and off. The woman tested positive. Because she is breastfeeding an 11-month-old baby l commenced her on Option B+. l tested the baby with antibody RDT [rapid diagnostic test] and tested negative. l commenced the baby on cotrimoxazole prophylaxis. The question is: Was it necessary for the baby to be given NVP [nevirapine] prophylaxis since the baby tested negative and is now 11 months OR should l give the baby NVP prophylaxis for 6wks from now????
Elizabeth received a range of responses from her cohort:
One member of the cohort was a district nursing officer (DNO). He shared that he had deliberately delayed responding until others had weighed in. He not only gave advice but also encouraged the group to refresh themselves on the resources available on their tablets:
Sorry for a late response. Remember key things in your scenario: mother is positive, baby is breastfeeding and is 11 months. … Infant is still at risk, therefore cotri prophy, infant feeding counselling and a continuation of routine FCH [family and child health] care will help. Then 6wks after stopping breastfeeding conduct rapid HIV test again. If negative stop cotri prophy and continue routine care. If positive CT cotri prophy, initiate ART.
He then referred Elizabeth to an algorithm in the national ART guidelines, which were included for easy reference in an application on the participants’ tablets.
This exchange showed the potential use of WhatsApp for support in clinical decision making, in the absence of a warmline for consultation. Upon returning to the classroom, participants engaged in discussion around the WhatsApp conversations, with particular attention paid to the case that Elizabeth had brought to the group. Other members of the cohort reported that they had watched the exchange with interest though they did not contribute.
The cohort members reported that the case was educational for them, and many of them indicated that they would like to continue their group for ongoing support.
As for Elizabeth’s young client, a rapid test was collected and returned negative. Results of the DNA test are still being awaited by the group with much interest. As one member wrote: “We cannot afford to lose that child, wherever she is. … She is still our child.”
To the brass beats of the Prince Edward School Jazz Band, on Feb. 6, a crowd of approximately 150 government officials, health professionals, and members of the press celebrated the launch of three programs in Zimbabwe, two of which are implemented by I-TECH Zimbabwe and partners. These vital programs aim to build local capacity and provide comprehensive services to prevent and combat HIV/AIDS in the country.
Speaking at the festivities were David Bruce Wharton, U.S. Ambassador to the Republic of Zimbabwe; Dr. Owen Mugurungi, director of the AIDS and TB Unit at the Ministry of Health and Child Care (MOHCC); Dr. King Holmes, Chair of the Department of Global Health at the University of Washington; Dr. Ann Downer, Executive Director of the International Training and Education Center for Health (I-TECH); and Dr. Batsirai Makunike-Chikwinya, Country Director of I-TECH Zimbabwe.
“Preventing the spread of HIV/AIDS is important to all of us, as is providing the best level of care to those living with this disease,” said Amb. Wharton. “Today we celebrate the launch of programs that will help us reach these goals together – programs that were designed together, by dedicated teams of collaborating partners from Zimbabwe and from the United States.”
In this spirit of collaboration, the programs, totaling $65 million over five years, support the Zimbabwe MOHCC with grant funding by the U.S. President’s Emergency Plan for AIDS Relief (PEPFAR), technical support from the Centers for Disease Control and Prevention, and implementation by local and U.S.-based partners. These partners include I-TECH; Zimbabwe Association of Church-Related Hospitals; Zimbabwe Community Health Intervention Research Project; Compre Health Services; The Newlands Clinic and Newlands Clinic Training Centre; Pangaea Global AIDS Foundation, Zimbabwe; and the University of Zimbabwe-University of California, San Francisco Collaborative Research Programme.
The Training and Mentoring Program seeks to develop and deliver in-service training on antiretroviral therapy, including the medical management of HIV/AIDS, women’s reproductive health, tuberculosis (TB), and TB/HIV co-infection to 8,000 health care workers across the country over five years. A mentorship component will also provide health care workers with access to ongoing learning and feedback on clinical issues. Health workers will receive refresher trainings via distance learning technologies, and the effectiveness of the program will be measured through a training database.
Also celebrated – and accompanied by a ribbon-cutting and presentation of 17 new vehicles – was the launch of the Voluntary Medical Male Circumcision Program. The program, building on work that started last spring, seeks to deliver services to 412,000 men in Zimbabwe between the ages of 15 and 49 years over the next five years. Medical male circumcision has proved very effective in preventing the spread of HIV. Randomized controlled trials in Uganda, Kenya, and South Africa have shown that this intervention reduces the risk of female-to-male sexual transmission of HIV by approximately 60%.
“Together, these two programs will improve the effectiveness and quality of prevention, treatment, and care services for those affected by HIV/AIDS – and create better health systems for all Zimbabweans,” said Dr. Holmes.
A new award to I-TECH seeks to fight the spread of HIV in Zimbabwe by rapidly scaling up training and mentoring of the country’s medical staff.
