Item 1270. HIV Drug Resistance and Viral Outcomes after 2nd-line Antiretroviral Failure in Kenya(Oxford University Press, 2022) Ali, Shamim M.; Humphrey, John; Novitsky, Vladimir; Sang, Edwin; DeLong, Allison; Jawed, Bilal; Kemboi, Emmanuel; Goodrich, Suzanne; Gardner, Adrian; Hogan, Joseph W.; Kantor, Rami; Medicine, School of MedicineBackground: Program data on HIV drug resistance and clinical outcomes after 2nd-line antiretroviral therapy (ART) failure in resource-limited settings are limited, yet can inform care, particularly with better ART access and options. Methods: We examined resistance upon 2nd-line failure and subsequent viral outcomes at the Academic Model Providing Access to Healthcare (AMPATH) in Kenya. Charts of people with genotypes upon 2nd-line failure up to 6/2021 were reviewed; and associations with viral suppression (< 1000 copies/mL) closest to 12 months post-genotyping were determined using bi- and multivariate analyses, adjusting for age, sex, time on ART, switch to 3rd-line (darunavir-, dolutegravir-, and/or raltegravir-based ART), and any resistance to regimens upon viral load (VL) testing. Results: Of 194 participants (53% female; median age 41 years; median 3.3 and 4.1 years on 1st- and 2nd-line), 60% were on lopinavir/ritonavir and 40% on atazanavir/ritonavir-based regimens. Overall, 178 (92%) had any resistance: 19% mono-, 40% dual-, 41% triple-class; 79% to NRTIs; 81% NNRTIs; and 43% PIs - 33% of those on lopinavir/ritonavir; 58% on atazanavir/ritonavir (p< 0.001); 24% with intermediate-high predicted resistance to darunavir/ritonavir (12 upon LPV/ritonavir, and 8 upon atazanavir/ritonavir failure; p=0.98). Of 140/194 people with post-genotype VLs, 55% stayed on 2nd-line, and 45% switched to 3rd-line. Of those 140, 72% virally suppressed (89% who switched to 3rd-line; 58% who didn't), and 75% had any resistance to their regimen at post-genotype VL (90% who switched to 3rd-line; 62% who didn't). In bivariate analysis, suppression was associated with switching to 3rd-line, and with resistance upon VL testing (Table). In multivariate analysis, suppression remained more likely among those who switched to 3rd-line, and association with resistance was less pronounced. Conclusion: In a large Kenyan HIV program, high resistance upon 2nd-line failure, high failure rates, and suppression association with 3rd-line switch suggest the need for dedicated management of this vulnerable population. Potential association between resistance and better viral outcomes, similar to reports upon 1st-line failure, needs further data and suggests significance of inadequate adherence.Item A framework for reinitiating global academic exchange in the context of the COVID-19 pandemic(IJME, 2022-09-09) Kelly, Caitrin M.; Some, Fatma; Guiles, Daniel A.; Turissini, Matthew; Gardner, Adrian; Litzelman, Debra K.; Medicine, School of MedicineItem Career choices and global health engagement: 24-year follow-up of U.S. participants in the Indiana University-Moi University elective(Elsevier, 2015-12) Umoren, Rachel A.; Gardner, Adrian; Stone, Geren S.; Helphinstine, Jill; Machogu, Emily P.; Huskins, Jordan C.; Johnson, Cynthia S.; Ayuo, Paul O.; Mining, Simeon; Litzelman, Debra K.; Department of Medicine, IU School of MedicineBackground Global health experiences evoke a profound awareness of cultural differences, inspire learners to prioritize professional values, and provide a lens for addressing global health care challenges. This study compares the long-term career and practice choices of participants in a 2-month Indiana University-Moi University, Kenya elective from 1989–2013 with those of a control group. Methods Global health elective (GHE) participants and a random sample of alumni without GHE experience were surveyed on their clinical practice, public health and global health activities. Results Responses from 176 former participants were compared with a control group of 177 alumni. GHE participants were more likely than similar controls to provide care to underserved U.S. populations (p=0.037), spend time in global health, public health, and public policy activities (p=0.005) and be involved in global health advocacy (p=0.001). Using multivariable analysis, GHE participants were more likely to be generalists (p<0.05), report that healthcare costs influenced medical decision-making (p<0.05), and provide healthcare outside the U.S. for ≥1 week/year (p<0.001). Conclusions Many years out of training, GHE participants were more likely to be generalists working with underserved populations, to be cost-conscious in their healthcare decision-making, and to be involved in global health, public health or public policy. Implications With the primary care provider shortage and need for greater awareness among providers of healthcare costs, our study shows that that global health experiences may yield broader benefits to the U.S. medical system.Item Correction: [On Becoming a Global Citizen: Transformative Learning Through Global Health Experiences](Ubiquity Press, 2021-03-16) Litzelman, Debra K.; Gardner, Adrian; Einterz, Robert M.; Owiti, Philip; Wambui, Charity; Huskins, Jordan C.; Schmitt-Wendholt, Kathleen M.; Stone, Geren S.; Ayuo, Paul O.; Inui, Thomas S.; Cottingham, Ann H.; Umoren, Rachel A.; Medicine, School of Medicine[This corrects the article DOI: 10.1016/j.aogh.2017.07.005.].Item Developing Ethical and Sustainable Global Health Educational Exchanges for Clinical Trainees: Implementation and Lessons Learned from the 30-Year Academic Model Providing Access to Healthcare (AMPATH) Partnership(Ubiquity Press, 2020-10) Turissini, Matthew; Mercer, Tim; Baenziger, Jenny; Atwoli, Lukoye; Einterz, Robert; Gardner, Adrian; Litzelman, Debra; Ayuo, Paul; Medicine, School of MedicineBackground: There is strong interest among healthcare trainees and academic institutions in global health rotations. There are a number of guidelines detailing the ethical principles for equitable and ethical global health rotations and bilateral exchanges, but it is often challenging to know to implement those principles and develop longstanding partnerships. Objectives: The Academic Model Providing Access to Healthcare (AMPATH) is a 30-year continuous partnership between a consortium of 12 universities in North America and Moi University in Kenya. The AMPATH bilateral educational exchange has had 1,871 North American and over 400 Kenyan clinical trainees participate to date. The article describes the bilateral exchange of trainees including curriculum, housing, and costs and discusses how each is an application of the principles of ethical global engagement. Findings: The article takes the experiences of the AMPATH partnership and offers practical strategies for implementing similar partnerships based on previously published ethical principles. Conclusions: AMPATH provides a model for developing an institutional partnership for a bilateral educational exchange grounded in cultural humility, bidirectional relationships, and longitudinal, sustainable engagement.Item Do clinical decision-support reminders for medical providers improve isoniazid preventative therapy prescription rates among HIV-positive adults? Study protocol for a randomized controlled trial(BioMed Central, 2015-04-09) Green, Eric P.; Catalani, Caricia; Diero, Lameck; Carter, E. Jane; Gardner, Adrian; Ndwiga, Charity; Keny, Aggrey; Owiti, Philip; Israelski, Dennis; Biondich, Paul; Department of Medicine, IU School of MedicineBACKGROUND: This document describes a research protocol for a study designed to estimate the impact of implementing a reminder system for medical providers on the use of isoniazid preventative therapy (IPT) for adults living with HIV in western Kenya. People living with HIV have a 5% to 10% annual risk of developing active tuberculosis (TB) once infected with TB bacilli, compared to a 5% lifetime risk in HIV-negative people with latent TB infection. Moreover, people living with HIV have a 20-fold higher risk of dying from TB. A growing body of literature suggests that IPT reduces overall TB incidence and is therefore of considerable benefit to patients and the larger community. However, in 2009, of the estimated 33 million people living with HIV, only 1.7 million (5%) were screened for TB, and about 85,000 (0.2%) were offered IPT. METHODS/DESIGN: This study will examine the use of clinical decision-support reminders to improve rates of initiation of preventative treatment in a TB/HIV co-morbid population living in a TB endemic area. This will be a pragmatic, parallel-group, cluster-randomized superiority trial with a 1:1 allocation to treatment ratio. For the trial, 20 public medical facilities that use clinical summary sheets generated from an electronic medical records system will participate as clusters. All HIV-positive adult patients who complete an initial encounter at a study cluster and at least one return encounter during the study period will be included in the study cohort. The primary endpoint will be IPT prescription at 3 months post the initial encounter. We will conduct both individual-level and cluster-level analyses. Due to the nature of the intervention, the trial will not be blinded. This study will contribute to the growing evidence base for the use of electronic health interventions in low-resource settings to promote high-quality clinical care, health system optimization and positive patient outcomes. Trial registration ClinicalTrials.gov NCT01934309, registered 29 August 2013.Item Frequency and factors associated with adherence to and completion of combination antiretroviral therapy for prevention of mother to child transmission in western Kenya(Wiley, 2013-01-02) Ayuo, Paul; Musick, Beverly; Liu, Hai; Braitstein, Paula; Nyandiko, Winstone; Otieno-Nyunya, Boaz; Gardner, Adrian; Wools-Kaloustian, Kara; Medicine, School of MedicineIntroduction: The objective of this analysis was to identify points of disruption within the prevention of mother-to-child transmission (PMTCT) continuum from combination antiretroviral therapy (CART) initiation until delivery. Methods: To address this objective, the electronic medical records of all antiretroviral-naïve adult pregnant women who were initiating CART for PMTCT between January 2006 and February 2009 within the Academic Model Providing Access To Healthcare (AMPATH), western Kenya, were reviewed. Outcomes of interest were clinician-initiated change or stop in regimen, disengagement from programme (any, early, late) and self-reported medication adherence. Disengagement was categorized as early disengagement (any interval of greater than 30 days between visits but returning to care prior to delivery) or late disengagement (no visit within 30 days prior to the date of delivery). The association between covariates and the outcomes of interest were assessed using bivariate (Kruskal-Wallis test for continuous variables and the Chi-square test for categorical variables) and multivariate logistic regression analysis. Results: A total of 4284 antiretroviral-naïve pregnant women initiated CART between January 2006 and February 2009. The majority of women (89%) reported taking all of their medication at every visit. There were 18 (0.4%) deaths reported. Clinicians discontinued CART in 10 patients (0.7%) while 1367 (31.9%) women disengaged from care. Of those disengaging, 404 (29.6%) disengaged early and 963 (70.4%) late. In the multivariate model, the odds of disengagement decreased with increasing age (odds ratio [OR] 0.982; confidence interval [CI] 0.966-0.998) and increasing gestational age at CART initiation (OR 0.925; CI 0.909-0.941). Women receiving care at a district hospital (OR 0.794; CI 0.644-0.980) or tuberculosis medication (OR 0.457; CI 0.202-0.935) were less likely to disengage. The odds of disengagement were higher in married women (OR 1.277; CI 1.034-1.584). The odds of early disengagement decreased with increasing age at CART initiation (OR 0.902; CI 0.881-0.924). The odds of late disengagement decreased with increasing age at CART initiation (OR 0.936; CI 0.917-0.956). While they increased with higher CD4 counts at CART-initiation (OR 1.001; CI 1.000-1001) and in married women (OR 1.297; CI 1.000-1.695). Conclusions: In a PMTCT programme embedded in an antiretroviral treatment programme with an active outreach department, the majority (67.4%) of women remained engaged and received uninterrupted prenatal CART.Item Infective Endocarditis in Low- And Middle-Income Countries(Elsevier, 2017-02) Njuguna, Benson; Gardner, Adrian; Karwa, Rakhi; Delahaye, François; Department of Medicine, School of MedicineInfective endocarditis (IE) is a rare, life-threatening disease with a mortality rate of upto 25% and significant debilitating morbidities. Although much has been reported on contemporary IE in high income countries, conclusions on the state of IE in low and middle income countries (LMICs) are based on studies conducted before the year 2000. Furthermore, unique challenges in the diagnosis and management of IE persist in LMICs. This article is a review of IE studies conducted in LMICs documenting clinical experiences from the year 2000 to present. We present the causes of IE, management of patients with IE and the prevailing challenges in diagnosis and treatment of IE in LMICs.Item Leveraging the power of partnerships: spreading the vision for a population health care delivery model in western Kenya(BMC, 2018-05-08) Mercer, Tim; Gardner, Adrian; Andama, Benjamin; Chesoli, Cleophas; Christoffersen-Deb, Astrid; Dick, Jonathan; Einterz, Robert; Gray, Nick; Kimaiyo, Sylvester; Kamano, Jemima; Maritim, Beryl; Morehead, Kirk; Pastakia, Sonak; Ruhl, Laura; Songok, Julia; Laktabai, Jeremiah; Medicine, School of MedicineBACKGROUND: The Academic Model Providing Access to Healthcare (AMPATH) has been a model academic partnership in global health for nearly three decades, leveraging the power of a public-sector academic medical center and the tripartite academic mission - service, education, and research - to the challenges of delivering health care in a low-income setting. Drawing our mandate from the health needs of the population, we have scaled up service delivery for HIV care, and over the last decade, expanded our focus on non-communicable chronic diseases, health system strengthening, and population health more broadly. Success of such a transformative endeavor requires new partnerships, as well as a unification of vision and alignment of strategy among all partners involved. Leveraging the Power of Partnerships and Spreading the Vision for Population Health. We describe how AMPATH built on its collective experience as an academic partnership to support the public-sector health care system, with a major focus on scaling up HIV care in western Kenya, to a system poised to take responsibility for the health of an entire population. We highlight global trends and local contextual factors that led to the genesis of this new vision, and then describe the key tenets of AMPATH's population health care delivery model: comprehensive, integrated, community-centered, and financially sustainable with a path to universal health coverage. Finally, we share how AMPATH partnered with strategic planning and change management experts from the private sector to use a novel approach called a 'Learning Map®' to collaboratively develop and share a vision of population health, and achieve strategic alignment with key stakeholders at all levels of the public-sector health system in western Kenya. CONCLUSION: We describe how AMPATH has leveraged the power of partnerships to move beyond the traditional disease-specific silos in global health to a model focused on health systems strengthening and population health. Furthermore, we highlight a novel, collaborative tool to communicate our vision and achieve strategic alignment among stakeholders at all levels of the health system. We hope this paper can serve as a roadmap for other global health partners to develop and share transformative visions for improving population health globally.Item Mitigating The Burden Of Diabetes In Sub-Saharan Africa Through An Integrated Diagonal Health Systems Approach(Dove Press, 2019-10-31) Mercer, Tim; Chang, Alice C.; Fischer, Lydia; Gardner, Adrian; Kerubo, Immaculate; Tran, Dan N.; Laktabai, Jeremiah; Pastakia, Sonak; Medicine, School of MedicineDiabetes is a chronic non-communicable disease (NCD) presenting growing health and economic burdens in sub-Saharan Africa (SSA). Diabetes is unique due to its cross-cutting nature, impacting multiple organ systems and increasing the risk for other communicable and non-communicable diseases. Unfortunately, the quality of care for diabetes in SSA is poor, largely due to a weak disease management framework and fragmented health systems in most sub-Saharan African countries. We argue that by synergizing disease-specific vertical programs with system-specific horizontal programs through an integrated disease-system diagonal approach, we can improve access, quality, and safety of diabetes care programs while also supporting other chronic diseases. We recommend utilizing the six World Health Organization (WHO) health system building blocks – 1) leadership and governance, 2) financing, 3) health workforce, 4) health information systems, 5) supply chains, and 6) service delivery – as a framework to design a diagonal approach with a focus on health system strengthening and integration to implement and scale quality diabetes care. We discuss the successes and challenges of this approach, outline opportunities for future care programming and research, and highlight how this approach can lead to the improvement in the quality of care for diabetes and other chronic diseases across SSA.
