Global neurosurgery over a 60-year period: Conceptual foundations, time reference, emerging Co-ordinates and prospects for collaborative interventions in low and middle income countries.

Introduction: We evaluated salient initiatives invested in global neurosurgery over a 60-year period. Research question: What are the Phases, Achievements, Challenges, and Lessons of Global Neurosurgery. Methods: A 60-year retrospective study from 1960 to 2020 analyzing the major phases, lessons, and progress notes. We reviewed the foundational need questions and innovated tools used to answer them. Results: Three phases defining our study period were identified. In the early phase, birthing academic units and the onset of individual volunteerism were dominant concepts. The 2nd phase is summarized by the rise of volunteerism and surgical camps.The third phase is heralded by advocacy and strategies for achieving care equity. The defining moment is the Lancet commission for global surgery summit in 2015. Lessons include the need for evaluation of the resources of recipient and donor locations using novel global surgery tools. Conclusion: Global neurosurgery over the 60-year study period is summarized by indelible touchstones of personal and group efforts as well as triumphs derived from innovations in the face of formidable challenges.

Application of blended integrated revision course in clinical surgery in West Africa in response to Covid-19 pandemic: perception of trainee surgeons.

Background/Objective: This study assessed the surgery residents' evaluation of blended delivery of the 2020 Integrated Revision Course in Clinical Surgery (IRCCS) of the West African College of Surgeons undertaken as a result of COVID-19 pandemic. Methods: We performed a cross-sectional survey of 234 participants of the 2020 IRCCS using self-administered questionnaire. The survey assessed the previous traditional course and various aspects of the novel blended course using 5-point Likert scale. Results: Overall, 186 (79.5%) responded. The blended course had overall mean rating of 4.92 (on a 5-point scale) compared to 4.05 for the previous traditional course. Of the virtual aspect of the blended course, didactic lectures had the best mean rating of 4.32, while unmanned OSCE had the least with mean rating of 3.30. Aspects of the multicentre component of the blended course were rated highly with conduct of manned OSCE receiving the best mean rating of 4.26. The major challenge of the blended course format was poor internet connectivity (n =102; 54.8%). Conclusion: Blended format of surgical training course is well rated by the surgery residents, and may be an effective means of delivery of clinical and non-clinical course contents during periods of disruption.
