This study outlines what expert ACC providers across SSA, believe should be included in undergraduate anaesthesia education and training. The final list of 92 ‘essential’ topics and skills, along with identified effective pedagogical approaches, and most appropriate clerkship aims were all used to help build and deliver an inaugural ACC clerkship for MBBS students at UGHE in 2023.
There is a significant shortfall in PAP numbers in Rwanda. For a population of almost 13.8 million, there are currently just 30 physician specialists(3). This translates into the need for over 650 more physician anaesthesiologists in order for the country to meet the WFSA target of 5 providers per 100,000 of the population. This is a pattern, commonly observed across SSA and much of the Global South. This shortfall must be addressed through multiple avenues, with increased training of specialists an integral component (though not feasibly the only means of meeting this target). Interest in specialty training varies globally; one study in New Zealand identified that up to 15% of medical student cohorts were interested in undertaking postgraduate specialty training in anaesthesia(13), in contrast with just 0.7% of final year medical students in Nigeria according to a 2016 study(14). Chan et al. (15) surveying 79 medical students in Rwanda, found that 6% of final year students identified anaesthesia as one of their top 3 specialty choices. The authors in this study identified quality of exposure of students to anaesthesia practice during their medical school training as vital in shaping perceptions of and driving interest in anaesthesia specialisation - an observation paralleled across contexts and specialties in the existing literature(16–18). As such, the role of this Delphi study in helping to develop a high-quality expert-approved contextually relevant clerkship is vital. This approach was undertaken in part with the aim of increasing Rwandan students’ interest in entering into postgraduate training, thus helping to address the ongoing PAP shortfall. Furthermore, by specifically building a contextualised clerkship we hoped to address issues relating to medical students’ misperceptions regarding the practice of anaesthesia in Rwanda, highlighted by Tuyishime (19) in their response to Chan et al.. Tuyishime argued that reframing misperceptions of anaesthesia as a specialty was critical for improving enrolment numbers in postgraduate anaesthesia training for the country.
Whilst some have described current practice and subsequently extrapolated ‘best practice’ regarding the delivery of anaesthesia education for the undergraduate medical student(20–24), to date there have been few peer-reviewed publications describing the adoption of more systematic expert consensus-driven approaches to curriculum development. Some such studies have been undertaken in HICs where the model of clinical anaesthetic practice differs significantly from Rwanda and most of SSA(25–27). They therefore bear limited relevance for those striving to build a contextualised curriculum for Rwanda or elsewhere in SSA. In Ireland, Australia, and New Zealand, where these existing Delphi studies have been conducted, anaesthesia care is provided exclusively by PAP specialists with country-wide specialist workforce densities of 17.5, 20.6, and 18.3 per 100, 000 respectively; far in excess of the 0.22 per 100, 000 in Rwanda(2, 3). The vast majority of PAPs in Rwanda are located in urban-based teaching hospitals with the majority of anaesthesia care in rural district hospitals provided by NPAPs. As such, one might expect that the requirements of those graduating from medical school, the goals for an ACC clerkship, and the topics to be taught would differ across these contexts.
Overton et al.(26) found that the ideal duration of anaesthesia training for undergraduates should be 3–4 weeks with the most important aim being to produce safe interns, and the least important aim being the need to teach details of anaesthesia. Despite not explicitly identifying these parameters Rohan et al.(25) made similar recommendations, highlighting the optimal duration of 3–4 weeks and a clear emphasis on clinical exposure. Interestingly, in our study PAPs from across SSA felt a longer duration of placement was optimal with 31 of 51 respondents specifying that an 8 week placement was most appropriate. In line with the findings of Overton et al., our respondents from SSA felt that an ability to perform anaesthesia was least important. In contrast, gaining an understanding of the role of an anaesthesiologist and inspiring medical students to undertake anaesthesia specialty training were felt to be most important in our study - these goals were not identified in either of the other two Delphi studies. Understandably, there was a high degree of crossover of items identified across the 3 studies; airway management, cardiovascular resuscitation and fluid management, critical care, and pain assessment and management were integral content areas for all three contexts.
From the results of this Delphi study, three topics and skills stand out by their omission. Tracheal intubation (both as a knowledge topic and as a practical skill), spinal anaesthesia (as a practical skill), and perioperative medicine (as a knowledge topic) all did not meet consensus in the final round of the Delphi survey. Tracheal intubation and spinal anaesthesia (as practical skills) are included in the existing undergraduate curricula for Rwanda, at the University of Rwanda, whilst practical skill exposure during medical school has been shown to be associated with greater interest amongst graduating students in procedural specialties like surgery and anaesthesia(28). Perioperative medicine is increasingly considered to fall under the remit of the anaesthesiologist with the content of clear value for the students beyond just their ACC clerkship. For these reasons, and with the desire to produce graduates best equipped to provide high quality, holistic care for patients in rural settings, the clerkship delivery committee eventually opted to include all three topics and practical skills in the UGHE clerkship as ‘non-essential’ topics/skills.
Whilst 92 ‘essential’ topics or skills were identified through our Delphi study, notably the study also highlighted consensus from across the continent that undergraduate curricula should focus on inspiring students’ interest in ACC rather than ensuring the acquisition of specific knowledge and/or skills. In delivering a clerkship for students based on the results of this study, this was useful to consider given the long list of identified topics and skills combined with the relatively short period of time allotted. In operationalising the curriculum, a clerkship delivery committee utilised a range of educational approaches with the essential topics and skills highlighted as indicative content for the students ahead of commencement of the clerkship. An in-person intensive bootcamp week where students engaged in case-based classroom sessions along with simulation-based training was followed by 3-week clinical placements in the operating rooms and critical care units. During clinical placements, students engaged in regular hybrid format case presentations of patients they had helped care for. The bootcamp week sessions and content, the discussion points for case presentations, and both the formative and summative assessments were based primarily on the indicative content from the Delphi study.
Limitations
Given the fact that much of the anaesthesia care across SSA is provided by NPAPs, there may have been value in also surveying non-physician providers. This would have provided greater representation of those working in rural settings, rather than tertiary urban settings. The decision was made to limit distribution of the survey to physicians only as it is primarily physicians involved in medical education of undergraduate medical students and they thus are likely to have a greater understanding of educational needs, logistics, and feasibility of delivery. Furthermore, whilst the majority of physician providers are based in urban centres, they nonetheless do still have experience of delivering care in rural settings.
The number of survey respondents was sufficient and in line with standard Delphi methodology, however only 12 countries from across SSA were represented in the first two rounds of the survey. Respondents based across a broader spread of countries might have provided a more representative consensus. Attempts were made to distribute the survey as widely as possible but this may limit the generalisability of the results, particularly for less represented regions.
