Study Participants Demographics
All 25 Key Informants were at least 18 years old and 84% (n=21) were males. Only 18% (n=5) of the key informants were heads of academic or research institutions, 40% (n=10) were trainers at tertiary institutions (i.e. professors or lecturers), 52% (n=13) were EID researchers including 7 senior and 4 early-career researchers, 28% (n=7) were government officials, 16% (n=4) were in-service professionals i.e. consultants or employees of non-government organizations involved in EID research, surveillance and control. A majority 88% (n=22) had graduate-level training (i.e. 10 masters and 12 PhDs or MDs), 48% (n=12) of key informants were public health specialists and 32% (n=8) were basic biomedical scientists practicing either microbiology, immunology, virology, genomics or bioinformatics. Only 28% (n=7) of key informants were medical doctors and 11% (n=3) were veterinarians.
Current Capacity for EID research, surveillance and control
The reviewed literature revealed that the vast majority of Uganda’s capacity for infectious disease research, surveillance and control is centered around HIV/AIDS, TB, Malaria and viral hemorrhagic fevers e.g. Ebola and Marburg [21,22,23,24,25,26,27]. In 2001, Uganda adopted the World Health Organization’s Integrated Disease Surveillance and Response (IDSR) and the Uganda Ministry of Health (MoH) coordinates most of the on-going activities which largely focus on surveillance and control to meet the 2005 International Health Regulations (IHR) core capacities to prevent, detect and respond to infectious disease threats [28,29,30,31,32]. The Global Fund Project and the U.S. President’s Emergency Plan for AIDS Relief (PEPFAR) fund and provide technical support for most of the on-going surveillance and control activities in HIV/AIDS, TB and Malaria [33,34], and the few on-going research activities mainly involve clinical or community-based studies and a limited number of pre-clinical studies [35]. In 2020, the Essence on Health Research ranked Uganda as having Upper Medium Research Capacity based on the number of clinical trials, international grants (World RePORT), publications (PubMED) and training institutions offering PhDs[36]. However, research output is still low mainly due to structural barriers including inadequate funding and government support and coordination [37,38,39,40,41].
Evidence from the desk review was further corroborated by a majority of key informants. All key informants mentioned that Uganda has some capacity for infectious disease research, surveillance and control with particular strengths in field epidemiology. Fourteen informants mentioned that there is limited funding especially for EID research; 12 mentioned a lack of adequate laboratory capacity, especially in detecting new pathogens and developing interventions such as diagnostic tools, vaccines and therapeutics; 9 highlighted the lack of adequate multisectoral coordination and/or One Health approach. Below are quotes from some key informants highlighting the gaps in EID research, surveillance and control capacity in Uganda:
The research component [of EIDs] is very weak, but surveillance and control is okay. (KI_06).
They [EIDs] are only taken seriously if they emerge, if they are not there, no one listens so that is a challenge in itself. There is no funding. (KI_09)
So, when you are as a nation, you don’t have that first-line of capacity to be able to detect any emerging disease or characterize a pathogen, or develop a diagnostic, then you are too dependent on other people [countries with better capacity]. (KI_20)
The most challenging [aspect of EID research, surveillance and control] is working with different partners that have got different interests and managing those interests. (KI_10)
Relevant Training in EID Research, Surveillance and Control
In Uganda, Mak, MUST, GU and a few other public and private tertiary institutions are the predominant source of the health workforce including medical, veterinary and social scientists [42,43,44,45,46,47]. However, many Ugandan tertiary institutions have a limited capacity to offer training in the latest advances in science and technology to address Uganda’s challenges with EIDs [48,49,50,51,52,53,[54]. Makerere University is the premier human and animal health training and research institution in Uganda with MakCHS, MakCOVAB and MakCHUSS offering about 33 undergraduate programs and 66 graduate (Masters and/or PhD) programs that are relevant to EID research, surveillance and control [55,56,57]. All masters programs at Mak are classroom-based and involve 1 to 1.5 years of didactic lectures and 1 year of research. A majority of the PhD programs are research only programs where students only need to (1) conduct independent research and publish set-required peer-reviewed articles, and (2) enroll in select cross-cutting core course units (i.e. advanced research methods; philosophy of method and scholarly writing communication skills) and electives (i.e. information competence and management, advanced gender research methodology, advanced quantitative data analysis, advanced qualitative data analysis and clinical epidemiology) at MakCHS[58]. There are only a handful of fully-taught PhD programs that offer didactic classroom-based training in advanced courses that are relevant to EID research, surveillance and control including PhD in bioinformatics and genomics[59], PhD in Health Sciences[60] and PhD in Public Health[61]. A majority of the advanced training and research are affiliated with or hosted at MakCHS [62,63,64] with a few schools dominating the space i.e. the Makerere University School of Public Health (MakSPH), Makerere University School of Medicine (MakSOM) and Makerere University School of Biomedical Sciences (MakSBS) [65,66,67].
The vast majority of the advanced training programs in EID research, surveillance and control are donor-funded through North-South collaborations where foreign institutions provide placements/rotations for advanced knowledge, mentorship, and hands-on training in new technologies [68]. Recently concluded and on-going training programs include but are not limited to: 1) Uganda Public Health Fellowship Program (UPHFP)[69]; 2) Fogarty International Center Research Training Programs [70]; 3) Training of Ugandans in Basic and Translational Research on TB and Emerging Infectious Diseases [71]; 4) Research Training and Mentoring Program for Career Development of Faculty at Makerere University College of Health Sciences [72]; 5) Mbarara University Research Training Initiative [73]; 6) Makerere University/Uganda Virus Research Institute Centre of Excellence for Infection & Immunity Research and Training (MUII) [74]; 7) The Field Epidemiology Training Program (FETP); and 8) Fogarty Global Health Fellows, Northern Pacific Global Health Fellows consortium (Fogarty-NP) [75]; and 8) Swedish International Development Cooperation Agency (SIDA)[76].
Knowledge and Skills Gaps in Uganda
Many of the basic and advanced training programs in Uganda that are relevant to infectious disease research, surveillance and control focus on knowledge and skills development in primary health care (including clinical/laboratory diagnosis and case management), public health courses (e.g. epidemiology), and community engagement [77,78]. Compared to other low- and middle-income countries (LMICs), Uganda has a relatively good number of knowledgeable and skilled professional health workers (i.e. doctors, pharmacists, nurses, midwives, clinical officers and medical laboratory staff): Uganda’s IHR scores for health workforce in 2021 ranged between 3 and 4 which implies developed and demonstrated capacity especially in epidemiology and public health [79]. However, the ratio of professional health workers per 1000 population is still below WHO recommendations [80] and many of the past and present health workforce capacity building programs focus on increasing the number and quality of primary health care providers [81] and only a few (e.g. MUII) specifically develop cutting-edge knowledge and skills for researchers [82]. There are even fewer programs that support advanced training for veterinary and social scientists [83].
Lack of adequate advance research training programs has left significant knowledge and skills gaps among researchers in Uganda which are especially highlighted by the low quantity and quality of research outputs including innovations and scientific publications with high h-index journals [84]. Many scholars have documented the need for capacity in advanced laboratory/basic biomedical sciences (e.g. genetics and bioinformatics) social sciences, implementation science, research leadership, research ethics, mentorship and professional scientific writing [85,86,87,88]. Evidence from the desk review was corroborated by a majority of key informants. Fourteen key informants commented on the lack of an adequate pool of researchers, and a majority stated that Uganda requires cadres with advanced training in epidemiology (n=13) and laboratory/basic biomedical sciences (n=12) including virology, microbiology, genomics, bioinformatics, molecular biology, vaccinology, and immunology. Below are quotes from some key informants:
The issue is most of the people [health workers] are not researchers and they are practitioners, but how do they apply research knowledge in their practice, that is power question. (KI_13).
Biostatistics, epidemiology, biological dynamics of the diseases and the sociological understanding of the [disease]; you have to understand them. (KI_11)
I would recommend a background in some basic science, actually going back to physics, but certainly chemistry. And some of the [Ugandan] students I worked with in Europe, it was really, it was surprising how little they really understood the methods they were using, they didn’t, they could barely tell me how PCR [polymerase chain reaction] was working and what the chemical structure of the base-pair was or how that is influenced by salt or temperature and things like that. (KI_18)
In addition, several key informants mentioned that multidisciplinary knowledge and skills are required including leadership (n=7), teamwork/interpersonal/soft skills (n=8), infection prevention and control (n=6), risk analysis (n=7), qualitative research and community engagement (n=7), and scientific writing (n=5). Sixteen key informants mentioned the relevance of knowledge and skills in research ethics. Below are quotes from some of the key informants:
You must have managerial and administrative skills because you can’t be head of those [EID research, surveillance and control] programs when you can’t supervise people. (KI_16)
It is very important to have an understanding of the society, how it perceives and sees and understands the infectious diseases. (KI_11)
People being able to write well is a rare skill in our part of the world. (KI_02)
One of the issues we have had is that these [EID] outbreaks come very quickly; they don’t give you time to write proposals, go to ethics and all that, we have to move very quickly. So, one of the, I think, approaches [to navigate ethical processes during EID outbreaks] that has been used and we are also using it, is to have ready protocols. In case there are any outbreaks, we can have quick approvals [if] the protocols are ready. (KI_23)
Present and Future Training Approaches
Constructivist approaches to pedagogy i.e. Problem-based learning (PBL) and community-based education and services (COBES) were introduced at MakCHS in the 2003/2004 academic year to replace traditional instructor-led approaches [89,90,91]. PBL is an effective student-centered approach that encourages critical thinking and independent learning [92] whereas COBES develops competencies to handle setting-specific and community-level health challenges [93,94]. To augment PBL and COBES, Blended Learning (BL) was also adopted at Mak and other tertiary institutions in Uganda. BL (also known as hybrid learning) integrates traditional instructor-led classroom-based training with digital technology including electronic-learning(e-learning) [95,96,97]. E-learning (e.g. on-line lectures and simulation-based medical education) gained widespread application during the COVID-19 pandemic, however the approach has several key drawbacks in LMICs including high costs and unreliable power and internet [98,99].
BL is particularly applicable in North-South collaborations where Ugandan students can attend on-line lectures and learn from subject-matter experts and peers from across the world without the need for travel [100]. In Uganda, BL has somewhat overtaken Joint Degree (sandwich) programs (e.g. the Mak and Karolinska Institutet program) where students had most of their training at Mak but traveled to Sweden for specialized PhD courses, data analysis, thesis writing and supervision [101] because sandwich programs may be costly and have low output [102]. The aforementioned training approaches are augmented by experiential learning (e.g. clinic, laboratory and field placements), continuous medical education (CME), training workshops covering various topics, fellowships (e.g. MUII and FETP), mentorship and multidisciplinary training programs (e.g. One Health Institute at Mak) [103,104,105,106,107,108,109]
Evidence about current training approaches in Uganda was corroborated by nearly all key informants. Key informants further recommended BL training programs that offer either (1) advanced graduate and post-graduate education that is abreast with contemporary advances in scientific knowledge and technology and aligned to Uganda’s setting-specific challenges with EIDs; or (2) robust short-term courses and experiential learning opportunities in multidisciplinary skills including data collection and leadership. Eleven key informants suggested that formative skills development should be achieved through long-term advanced graduate training i.e. masters, PhD and post-doctoral programs, 5 key informants recommended short-term didactic courses for in-service professionals who may need advanced training but may not be able to commit to full-time training programs. 5 key informants recommended that novel training programs should be aligned to target audiences and specific knowledge and skills required in Uganda. Below are quotes from some of the key informants:
Science is dynamic, things keep on changing. So, what we knew in the past is not exactly the same today. So because of that, we need to train people in conducting research because it is through research that we are able to understand things [EID outbreaks] better. (KI_03)
Masters [degree] is good but masters is not so transformative. But if you want to have a sustainable impact, then you have to train Ugandans at PhD level in that area [of EID research, surveillance or control] and in use of contemporary technologies to tackle them [EID outbreaks]. You rather train two or three PhD [students] and train them properly, say in USA, and tell them you go and come back [to Uganda] where we don’t have capacity than train fifteen masters, we will have the numbers but we won’t have an impact. (KI_09)
I guess different components [of EID research, surveillance or control] will require different things [trainings], but I think it will be very good to have people [health workers] in master’s laboratory training [and at] PhD level, because then, there you know people can do [the work]. At that level they can possibly develop either vaccines, or drugs and all that. But also, being able to manage [patients] and identify and understand the dynamics of the various infectious diseases in [a] given context [of the] people. So, but again maybe one important point is that all this is not about, I think, people in medicine [clinical and laboratory personnel], but also, we make sure we co-opt, we bring in multidisciplinary [practitioners]. (KI_11)
Don’t only look at university training [only], we may train a community health worker, may be for 3 months [and] we give them the necessary skills to collect information [about EID outbreaks]. (KI_01)
