ABSTRACT

In many low- and middle-income countries, there seems to be a mismatch between graduate skills and healthcare industry requirements due to variability in curricula. With the current increased global demand for competent health profession graduates, harmonizing competency-based curricula (CBC) is necessary to address this mismatch. This paper describes how three health professions training universities in Tanzania and their two long-standing United States partners embarked on developing harmonized CBC for undergraduate medicine and nursing degrees. The main goal of the activity was to develop templates to harmonize curricula that would support graduates to acquire mandatory national Graduate Minimum Essential Competencies (GMEC) irrespective of the institution of their training. The paper describes the processes of engaging multiple institutions, the professions of medicine and nursing and various stakeholders to develop mandatory curricula generic competencies, creating milestones for assessing competencies, training faculty at each of the three partnering institutions in curriculum delivery and assessments, resulting in the adoption of the curricula by the University leadership at each institution. Ultimately the Tanzania Commission for Universities (TCU) a regulatory body required all schools of medicine and nursing in the country to adopt the curricula, thus creating a harmonized national standard for teaching medicine and nursing beginning October 2022.

ABSTRACT

Background: Effective implementation of new curricula requires faculty to be knowledgeable about curriculum goals and have the appropriate pedagogical skills to implement the curriculum, even more so if the new curriculum is being deployed at multiple institutions. In this paper, we describe the process of creating a common faculty development program to train cross-institutional faculty developers to support the implementation of national harmonized medicine and nursing curricula. Methods: A five-step approach was used, including a cross-institutional needs assessment survey for faculty development needs, the development of a generic faculty development program, the identification and training of cross-institutional faculty educators, and the implementation of cross-institutional faculty capacity-building workshops. Results: A list of common cross-cutting faculty development needs for teaching and learning was identified from the needs assessment survey and used to develop an accredited, cross-institutional faculty development program for competency-based learning and assessment. A total of 24 cross-institutional faculty developers were identified and trained in 8 core learning and assessment workshops. A total of 18 cross-institutional and 71 institutional workshops were conducted, of which 1292 faculty members and 412 residents were trained, and three cross-institutional educational research projects were implemented. Conclusion: The success attained in this study shows that the use of cross-institutional faculty developers is a viable model and sustainable resource that can be used to support the implementation of harmonized national curricula.

ABSTRACT

Background: In 2012, the Muhimbili University of Health and Allied Sciences (MUHAS) embarked on structured competency-based curricula (CBC) for its programmes. Other health profession training institutions continued with their traditional way of teaching and thus causing variability in the competencies of the graduates. We aimed to analyze the experiences of different stakeholders on the implementation of CBC specifically on biomedical sciences by MUHAS to inform the development of harmonized competency-based curricula in three health professional training institutions in Tanzania. Methods: We adopted an exploratory case study to analyse the implementation of CBC in programmes of Medicine and Nursing involving MUHAS graduates, immediate supervisors at the employment sites, faculty, and continuing students at MUHAS. Kiswahili guides were used to conduct the in-depth interviews (IDIs) and focus group discussions (FGDs). Qualitative content analysis was adopted for analysis. Results: From the 38 IDIs and 15 FGDs, four categories of human resources teaching and learning environment; curriculum content; and support systems emerged. Human resources were attributed to the shortage of an adequate number of faculty and teaching skills variation. The curriculum content category was linked to the redundancy of courses or topics, poor sequencing of some topics or courses, and limited time for teaching some essential courses or topics. Training and practice area mismatch, accommodation to students, teaching space, and library were the sub-categories linked to teaching and learning environment. Lastly, support systems related to teaching methods and opportunities for improving teaching and learning were revealed. Conclusion: The findings of this study highlight the challenges and opportunities for the implementation of CBC. The solutions to the revealed challenges are beyond the training institutions' capacity. The latter call for multi-stakeholder engagement including those from the public and private sectors in health, higher education and finance for common and sustainable solutions.

ABSTRACT

BACKGROUND: In Tanzania, the International Working Formulation [WF] rather than the WHO Classification is still being used in diagnosing malignant lymphomas (ML) and the biological characterization including the HIV/EBV association is sketchy, thus restraining comparison, prognostication and application of established therapeutic protocols. METHODS: Archival, diagnostic ML biopsies (N = 336), available sera (N = 35) screened by ELISA for HIV antibodies and corresponding clinical/histological reports at Muhimbili National Hospital (MNH) in Tanzania between 1996 and 2006 were retrieved and evaluated. A fraction (N = 174) were analyzed by histopathology and immunohistochemistry (IHC). Selected biopsies were characterized by flow-cytometry (FC) for DNA ploidy (N = 60) and some by in-situ hybridization (ISH) for EBV-encoded RNA (EBER, N = 37). RESULTS: A third (38.8%, 109/281) of the ML patients with available clinical information had extranodal disease presentation. A total of 158 out of 174 biopsies selected for immunophenotyping were confirmed to be ML which were mostly (84. 8%, 134/158) non-Hodgkin lymphoma (NHL). Most (83.6%, 112/134) of NHL were B-cell lymphomas (BCL) (CD20+), of which 50.9%, (57/112) were diffuse large B-cell (DLBCL). Out of the 158 confirmed MLs, 22 (13.9%) were T-cell [CD3+] lymphomas (TCL) and 24 (15.2%) were Hodgkin lymphomas (HL) [CD30+]. Furthermore, out of the 60 FC analyzed ML cases, 27 (M:F ratio 2:1) were DLBCL, a slight majority (55.6%, 15/27) with activated B-cell like (ABC) and 45% (12/27) with germinal center B-cell like (GCB) immunophenotype. Overall, 40% (24/60) ML were aneuploid mostly (63.0%, 17/27) the DLBCL and TCL (54.5%, 6/11). DNA index (DI) of FC-analyzed ML ranged from 1.103-2.407 (median = 1.51) and most (75.0%) aneuploid cases showed high (>40%) cell proliferation by Ki-67 reactivity. The majority (51.4%, 19/37) of EBER ISH analyzed lymphoma biopsies were positive. Of the serologically tested MLs, 40.0% (14/35) were HIV positive, mostly with high (> or =40.0%) Ki-67 reactivity. CONCLUSIONS: According to the 2001 WHO Classification, most subtypes are represented in Tanzanian ML. Extranodal presentation was common among MNH lymphoma patients who also showed high aneuploidy, tumor proliferation (KI-67) and EBER positivity. DLBCL was frequent and phenotype heterogeneity appeared similar to observations in Western countries suggesting applicability of established intervention approaches. HIV was apparently associated with high ML cell proliferation but extended studies are needed to clarify this.

ABSTRACT

ISSUES: The scarcity of pathologists in sub-Saharan Africa is a well established fact that is attributable to few training programmes in the region; this is further compounded by the lack of harmonised curricula, training and exams within and without member countries. DESCRIPTION OF THE INTERVENTION: Through the Association of Pathologists of East, Central and Southern Africa, the College of Pathologists of East, Central and Southern Africa (COPECSA) was formed with the clear-cut goal of establishing a regional and internationally recognised college to support and inform good quality medical and laboratory practice by promoting leadership, mentorship and excellence in the safe practice of pathology through training, exams, accreditation, advocacy and professional development for health. LESSONS LEARNT: Since its inception in 2010, COPECSA has conferred fellowships to 120 practising pathologists in the East, Central and Southern Africa in partnership with international organisations; the college has been awarded five competitive grants and conducted several quality improvement workshops. RECOMMENDATIONS: This paper describes the journey that COPECSA has made towards standardising the practice and training of pathology in the East Central and Southern Africa region.

ABSTRACT

This paper describes accelerating development of programs in global health, particularly in North American academic institutions, and sets this phenomenon in the context of earlier programs in tropical medicine and international health that originated predominantly in Europe. Like these earlier programs, the major focus of the new global health programs is on the health needs of developing countries, and perhaps for this reason, few similar programs have emerged in academic institutions in the developing countries themselves. If global health is about the improvement of health worldwide, the reduction of disparities, and protection of societies against global threats that disregard national borders, it is essential that academic institutions reach across geographic, cultural, economic, gender, and linguistic boundaries to develop mutual understanding of the scope of global health and to create collaborative education and research programs. One indication of success would be emergence of a new generation of truly global leaders working on a shared and well-defined agenda--and doing so on equal footing.

ABSTRACT

OBJECTIVES: To evaluate human herpesvirus 8/Kaposi's sarcoma associated herpesvirus (HHV-8/KSHV) viral load in diagnostic, (formalin fixed, paraffinised) biopsies and patient serum during tumour progression of oral and cutaneous AIDS-related Kaposi's sarcoma (AKS), and endemic Kaposi's sarcoma (EKS) by a sensitive and specific quantitative real time polymerase chain reaction (qRT-PCR) assay. STUDY DESIGN: Eighty six biopsies of both AKS (oral and cutaneous AKS, 68) and EKS (cutaneous EKS, 18) were evaluated by qRT-PCR and immunohistochemistry (IHC). The viral load in human tumour tissue and serum of some individual patients were compared. RESULTS: Higher viral load as well as frequency of latency-associated nuclear antigen (LANA)+ tumour spindle cells (SC) and number of LANA granules per SC was found in oral AKS compared to cutaneous AKS. Although few cases were available, serum viral load appeared to decrease compared to tumour tissue during KS progression. CONCLUSIONS: The higher viral load in oral rather than cutaneous AKS is consistent with the well recognised reservoir function of the oral mucosa. Decrease of serum HHV-8 load during KS progression may indicate decreased virus release and/or increased virus clearance.

ABSTRACT

Oral Kaposi's sarcoma (OKS) from Tanzanian patients (78) at Muhimbili National Hospital/Muhimbili University College of Health Sciences corresponding to approximately 10% of KS registered during 1990-2005, were diagnosed (ELISA) as HIV-infected (OAKS) (74/78) and endemic KS (4/78). Females were 69.2% (54/78) with median age 31 and males 30.8% (24/78) with median age 38. More males (50%) had systemic KS than females (37%) and 4-times more multicentric OKS. All tested (34) oral KS patients sera had HHV-8 antibodies. Available (31/78) blood showed very low CD4+ T-lymphocyte counts. Most OKS (61.5%) had nodular histology. Immunostaining showed adult male nodular OAKS to have a significantly higher frequency of viral LANA+, endothelial CD34+ tumour spindle-cells (SC) and more Ki-67+ (median =24.1%) proliferating cells compared to females (17.2%). Juvenile nodular OAKS had more LANA+ and Ki-67+ cells than corresponding adult cases. Significantly more LANA+ and Ki-67+ cells were found in nodular OAKS compared to cutaneous HIV/AIDS Kaposi's sarcoma (CAKS). A positive correlation (60%) was found between the proliferation index (Ki-67+ cell frequency) and LANA+/CD34+ SC. OKS in Tanzania is since 1990, mostly seen in females, associated with HIV/AIDS and advanced (nodular) histopathology. Males have more systemic tumour burden while more females develop primary OAKS. HHV-8+ cells were more frequent in nodular male than female and in juvenile than adult nodular OAKS than cAKS. Higher tumoral HHV-8 content appeared to be correlated to proliferation index.

ABSTRACT

BACKGROUND: It is still unclear if Kaposi's sarcoma (KS) is a monoclonal cell proliferation or a polyclonal, hyperplastic, reactive process. Reports on KS cytogenetics are few and restricted to late stage disease and cell lines. METHOD: We analysed 27 KS, early and late, AIDS related (AKS) and endemic (EKS) by laser microdissection, global DNA amplification and comparative genomic hybridization (CGH). RESULT: Loss of Y chromosome was detected in 20/23 male KS, which was the only recurrent chromosomal aberration in all nine male early (patch) KS. Only one patch EKS showed in addition to the Y loss a loss of Xq. Late (nodular) AKS and EKS showed recurrent copy number changes in chromosomes 16, 17, 21, X and Y, as well as other random changes. The loss of chromosome 16, 17 and Y was confirmed by interphase fluorescence in situ hybridization (FISH) on paraffin sections. EKS showed a higher number of chromosomal abnormalities than AKS, indicating that rapid growth of AKS is less dependent on genetic changes than is EKS, possibly because of the immunosuppressed host environment in AKS. CONCLUSION: Clonal loss of chromosome Y was detected in all early male KS, while additional chromosomal aberrations appeared during development to late KS. This increase in chromosomal abnormalities during tumour growth indicates genetic instability and the selection of survival cell clones establishing late, aggressive sarcoma growth. Our data support the view that KS (in males) develops into a clonal tumour yet initially is a hyperplastic reactive cell proliferation.

ABSTRACT

OBJECTIVE: Histologic chorioamnionitis has been associated with preterm birth and low birthweight. Our goal was to evaluate the relationship between polymorphonuclear cell and mononuclear cell placental infiltrations and adverse infant outcomes. STUDY DESIGN: Data from women who were enrolled in a trial of antibiotics for prevention of mother-to-child transmission of HIV-1 and of preterm birth were analyzed. Women who had HIV and women who did not have HIV were assigned randomly to either metronidazole 250 mg and erythromycin 250 mg at 20 to 24 weeks of gestation 3 times daily for 7 days and metronidazole 250 mg and ampicillin 500 mg every 4 hours during labor or identical placebos. Women with HIV were offered nevirapine at delivery for the prevention of mother-to-child transmission. At delivery, various placental sites were evaluated for polymorphonuclear cell and mononuclear cell infiltration. RESULTS: Polymorphonuclear and mononuclear cell infiltrations were common in the decidua (18% and 43%, respectively) and chorioamnion (28% and 34%, respectively). Gestational age and birthweight were lower among women with polymorphonuclear cell infiltrations, with these relationships generally stronger at earlier gestational age and birthweight. Mononuclear infiltrations were not associated with adverse outcomes. Neither polymorphonuclear cell nor mononuclear placental infiltrations were associated with mother-to-child transmission of HIV. Antibiotic use was not associated with reduced polymorphonuclear or mononuclear cell infiltrations. CONCLUSION: Polymorphonuclear cell infiltrations were associated with preterm birth and decreased birthweight and gestational age. Antibiotic use was not associated with reductions in polymorphonuclear or mononuclear cell infiltrations. In this nevirapine-treated population, neither polymorphonuclear nor mononuclear cell infiltration was associated with the mother-to-child transmission of HIV.

ABSTRACT

BACKGROUND: Faced with one of the lowest physician-to-population ratios in the world, the Government of Tanzania is urging its medical schools to train more physicians. The annual number of medical students admitted across the country rose from 55 in the 1990s to 1,680 approved places for the 2015/16 academic year. These escalating numbers strain existing faculty. OBJECTIVE: To describe the availability of faculty in medical schools in Tanzania. DESIGN: We identified faculty lists published on the Internet by five Tanzanian medical schools for the 2011/12 academic year and analyzed the appointment status, rank, discipline, and qualifications of faculty members. RESULTS: The five schools reported 366 appointed faculty members (excluding visiting, part-time, or honorary appointments) for an estimated total enrolled student capacity of 3,275. Thirty-eight percent of these faculty were senior lecturers or higher. Twenty-seven percent of the appointments were in basic science, 51% in clinical science, and 21% in public health departments. The most populated disciplines (more than 20 faculty members across the five institutions) were biochemistry and molecular biology, medicine, obstetrics and gynecology, pediatrics, and surgery; the least populated disciplines (less than 10 faculty members) were anesthesiology, behavioral sciences, dermatology, dental surgery, emergency medicine, hematology, ophthalmology, orthopedics, otorhinolaryngology, oncology and radiology, psychiatry. These figures are only indicative of faculty numbers because of differences in the way the schools published their faculty lists. CONCLUSIONS: Universities are not recruiting faculty at the same rate that they are admitting students, and there is an imbalance in the distribution of faculty across disciplines. Although there are differences among the universities, all are struggling to recruit and retain staff. If Tanzanian universities, the government, donors, and international partners commit resources to develop, recruit, and retain new faculty, Tanzania could build faculty numbers to permit a quality educational experience for its doctors of tomorrow.

ABSTRACT

BACKGROUND: There is a great need for physicians in Tanzania. In 2012, there were approximately 0.31 physicians per 10,000 individuals nationwide, with a lower ratio in the rural areas, where the majority of the population resides. In response, universities across Tanzania have greatly increased the enrollment of medical students. Yet evidence suggests high attrition of medical graduates to other professions and emigration from rural areas where they are most needed. OBJECTIVE: To estimate the future number of physicians practicing in Tanzania and the potential impact of interventions to improve retention, we built a model that tracks medical students from enrollment through clinical practice, from 1990 to 2025. DESIGN: We designed a Markov process with 92 potential states capturing the movement of 25,000 medical students and physicians from medical training through employment. Work possibilities included clinical practice (divided into rural or urban, public or private), non-clinical work, and emigration. We populated and calibrated the model using a national 2005/2006 physician mapping survey, as well as graduation records, graduate tracking surveys, and other available data. RESULTS: The model projects massive losses to clinical practice between 2016 and 2025, especially in rural areas. Approximately 56% of all medical school students enrolled between 2011 and 2020 will not be practicing medicine in Tanzania in 2025. Even with these losses, the model forecasts an increase in the physician-to-population ratio to 1.4 per 10,000 by 2025. Increasing the absorption of recent graduates into the public sector and/or developing a rural training track would ameliorate physician attrition in the most underserved areas. CONCLUSIONS: Tanzania is making significant investments in the training of physicians. Without linking these doctors to employment and ensuring their retention, the majority of this investment in medical education will be jeopardized.

ABSTRACT

AIDS-associated Kaposi's sarcoma (AKS) is particularly aggressive and it is one of the principal neoplasms in regions of Africa affected by both high endemic HHV8 and epidemic HIV infection. In this study, serum samples from 18 patients with Kaposi's sarcoma from Tanzania, mostly males (n = 15 vs 3), were subjected to analysis with respect to HHV8-DNA load and antibody spectrum against the HIV-1 tat protein. Of the 18 patients, 14 were HIV-1-positive. The median HHV8 virus load in the HIV-1-positive group was 2075 DNA copies/ml, compared to 450 copies/ml in the HIV-1-negative group. In the HIV-1-positive group, the males had a higher HHV8-DNA virus load as compared to females (median: 4600 vs 1400 genome copies per ml). Since tat can promote AKS development (4-6) by intercellular signalling pathways, and these signals can be abolished by anti-tat IgG (7-9), we have examined the anti-tat IgG spectrum in this study. It would be expected that the levels of serum HHV8-DNA are higher in KS patients who have low anti-tat IgG titer, or who are anti-tat IgG-negative. In the present study, seven out of fifteen AKS patients were positive for anti-tat IgG. Although, we have not seen a strict quantitative relationship between serum anti-tat IgG and HHV8-DNA levels, our data appear to suggest a correlation between the two parameters. In view of these observations and the published data, we suggest that cross-signalling pathways between the tat protein and HHV8-DNA are involved in the complexity of pathogenesis of Kaposi's sarcoma.

ABSTRACT

Human herpesvirus 8 or Kaposi's sarcoma-associated herpesvirus (HHV8/KSHV) is believed to be the most important etiopathological factor of Kaposi's sarcoma (KS) and some specific types of malignant lymphomas. The diagnostic and prognostic significance of serum viral load in endemic (African) areas is poorly understood. In AIDS-related KS (AKS) it has been shown that HIV-Tat may be of pathogenic importance and that immunoreactivity to Tat may have prognostic significance. Here we report on the quantitative analysis of HHV8 DNA in serum from Tanzanian patients with KS (n = 19), either AIDS-related (AKS) (n = 14) or endemic KS (EKS) (n = 5) and non-KS control individuals (n = 4). Fourteen AKS sera were also tested for HIV-tat antibodies by a direct ELISA assay. In AKS patients detectable (12 out of 14) serum HHV8 DNA levels showed a median of 1400 copies/ml as compared to a median of 200 copies/ml for EKS, but for one AKS case with an exceptionally high level (25,500 copies/ml). The serum HHV8 DNA levels were usually higher in males (n = 17; median 580 DNA copies/ml) as compared to females (n = 6; median 120 DNA copies/ml) and in early, patch stages (n = 8; median 2,750 copies/ml) as compared to late, nodular stages (n = 11; median 200 DNA copies/ml). Of fourteen sera from AKS patients, seven were positive for antibody against HIV-1 tat. Epitope analysis of the anti-tat antibody spectrum showed reactivity to various non-functional sites, but not towards the functional epitopes 46-60 (TAR-binding region).

ABSTRACT

BACKGROUND: Tanzania is among Sub-Saharan countries mostly affected by the HIV and AIDS pandemic, females being more vulnerable than males. HIV infected women appear to have a higher rate of persistent infection by high risk types of human papillomavirus (HPV) strongly associated with high-grade squamous intraepithelial lesions (HSIL) and invasive cervical carcinoma. Furthermore, although HIV infection and cervical cancer are major public health problems, the frequency and HIV/HPV association of cervical cancer and HSIL is not well documented in Tanzania, thus limiting the development of preventive and therapeutic strategies. METHODS: A prospective unmatched, case-control study of HIV-seropositive, ≥ 18 years of age and consenting non-pregnant patients attending the care and treatment center (CTC) at Muhimbili National Hoospital (MNH) as cases was done between 2005 and 2006. HIV seronegative, non-pregnant and consenting women recruited from the Cervical Cancer Screening unit (CCSU) at ORCI were used as controls while those who did not consent to study participation and/or individuals under < 18 years were excluded. Pap smears were collected for routine cytodiagnosis and P53 immunohistochemistry (IHC). Cervical lesions were classified according to the Modified Bethesda System. RESULTS: A total of 170 participants from the two centers were recruited including 50 HIV-seronegative controls were from the CCSU. Ages ranged from 20-66 years (mean 40.5 years) for cases and 20-69 years (mean 41.6 years) for controls. The age group 36-45 years was the most affected by HIV (39.2%, n = 47). Cervicitis, squamous intraepithelial lesions (SIL) and carcinoma constituted 28.3% (n = 34), 38.3% (n = 46) and 5.8% (n = 7) respectively among cases, and 28% (n = 14), 34% (n = 17) and 2% (n = 1) for controls, although this was not statistically significant (P-value = 0.61). IHC showed that p53 was not detectable in HPV + Pap smears and cell blocks indicating possible degradation. CONCLUSIONS: The frequency of SIL and carcinoma appeared to be higher among HIV-infected women on HAART compared to seronegative controls and as expected increased with age. HIV seropositive patients appeared to present earlier with SIL compared to those HIV seronegative suggesting a role of HIV in altering the natural history of HPV infection and cervical lesions. The absence of p53 immunoreactivity in HPV + lesions is indicative of the ability of HPV E6 proteins to interact with the tumor suppressor gene and pave way for viral-induced oncogenesis in the studied Tanzanian women.

ABSTRACT

With a severe shortage of highly trained health professionals, Tanzania must make the best possible use of available human resources and support training institutions to educate more graduates. We highlight the overlooked but significant role of universities in collecting, managing, and using human resources data in Tanzania and in other countries struggling to build their health workforces. Although universities, professional councils, ministries of health, education, and finance, and non-governmental organizations in Tanzania all maintain databases that include details of health professionals' education, registration, and employment, they do not make the information easily accessible to one another. Using as an example Muhimbili University of Health and Allied Sciences - the leading public institution for health professions education in Tanzania - we explore how training institutions can gather and use data to target and improve the quality of education for increasing numbers of graduates. We specifically examine the substantial challenge universities face in locating more members of each graduating class and conclude with recommendations about how the situation can be improved.

ABSTRACT

In 2005, Muhimbili University of Health and Allied Sciences (MUHAS) in Tanzania and the University of California San Francisco (UCSF) in the United States joined to form a partnership across all the schools in our institutions. Although our goal is to address the health workforce crisis in Tanzania, we have gained much as institutions. We review the work undertaken and point out how this education partnership differs from many research collaborations. Important characteristics include: (i) activities grew out of MUHAS's institutional needs, but also benefit UCSF; (ii) working across professions changed the discourse from 'medical education' to 'health professions education'; (iii) challenged by gaps in our respective health-care systems, both institutions chose a new focus, interprofessional team work; (iv) despite being so differently resourced, MUHAS and UCSF seek strategies to address growing class sizes; and (v) we involved a wider range of people - faculty, administrators, students, and residents - at both institutions than is usually the case with research. This partnership has convinced us to exhort other academic leaders in the health arena to seek opportunities together to enlighten and enliven our educational enterprises.

ABSTRACT

One of the major needs for medical schools and health systems in less affluent countries is system strengthening through the training and development of faculty, doctors, nurses, and other skilled health care workers. Partnering with medical schools in more affluent countries such as the United States is one potential approach for medical schools in underresourced areas, such as Sub-Saharan Africa. Most commonly, these partnerships have focused on research agendas or limited educational exchanges. In this perspective, the authors present an approach to strengthening collaborative relationships between three medical schools in the United States and four in Sub-Saharan Africa. The approach is explicitly focused on achieving partnerships that enable institutions to improve care. It developed from an initiative to fund partnerships or "collaboratives" that address 10 key learning questions determined to be central to focusing efforts on strengthening education systems and, in turn, improving health in Sub-Saharan Africa. The leaders of the schools involved in these partnerships met multiple times across three years to discuss how their collaboratives could address the ten learning questions including what is the best approach and what are the key ingredients for creating effective, multidimensional collaborations between academic institutions in the North and institutions in Sub-Saharan Africa. Collaboratively, they defined a framework of evidence that can be used for evaluating their current initiatives and, potentially, for structuring future partnerships.
