Neurosurgical Education in Tanzania: The Dar es Salaam Global Neurosurgery Course.

BACKGROUND: Postgraduate neurosurgical training is essential to develop a neurosurgical workforce with the skills and knowledge to address patient needs for neurosurgical care. In Tanzania, the number of neurosurgeons and neurosurgical services offered have expanded in the past 40 years. Training opportunities within the country, however, are not sufficient to meet the needs of residents, specialists, and nurses in neurosurgery, forcing many to train outside the country incurring associated costs and burdens. We report on the Dar es Salaam Global Neurosurgery Course, which aims to provide local training to neurosurgical health care providers in Tanzania and surrounding countries. METHODS: We report the experience of the Global Neurosurgery Course held in March 2023 in Dar es Salaam, Tanzania. We describe the funding, planning, organization, and teaching methods along with participant and faculty feedback. RESULTS: The course trained 121 participants with 63 faculty-42 from Tanzania and 21 international faculty. Training methods included lectures, hands-on surgical teaching, webinars, case discussions, surgical simulation, virtual reality, and bedside teaching. Although there were challenges with equipment and Internet connectivity, participant feedback was positive, with overall improvement in knowledge reported in all topics taught during the course. CONCLUSIONS: International collaboration can be successful in delivering topic-specific training that aims to address the everyday needs of surgeons in their local setting. Suggestions for future courses include increasing training on allied topics to neurosurgery and neurosurgical subspecialty topics, reflecting the growth in neurosurgical capacity and services offered in Tanzania.

The effect of the Dar es Salaam neurosurgery training course on self-reported neurosurgical knowledge and confidence.

Introduction: The Muhimbili Orthopaedic Institute in collaboration with Weill Cornell Medicine organises an annual neurosurgery training course in Dar es Salaam, Tanzania. The course teaches theory and practical skills in neurotrauma, neurosurgery, and neurointensive care to attendees from across Tanzania and East Africa. This is the only neurosurgical course in Tanzania, where there are few neurosurgeons and limited access to neurosurgical care and equipment. Research question: To investigate the change in self-reported knowledge and confidence in neurosurgical topics amongst the 2022 course attendees. Material and methods: Course participants completed pre and post course questionnaires about their background and self-rated their knowledge and confidence in neurosurgical topics on a five point scale from one (poor) to five (excellent). Responses after the course were compared with those before the course. Results: Four hundred and seventy participants registered for the course, of whom 395(84%) practiced in Tanzania. Experience ranged from students and newly qualified professionals to nurses with more than 10 years of experience and specialist doctors. Both doctors and nurses reported improved knowledge and confidence across all neurosurgical topics following the course. Topics with lower self-ratings prior to the course showed greater improvement. These included neurovascular, neuro-oncology, and minimally invasive spine surgery topics. Suggestions for improvement were mostly related to logistics and course delivery rather than content. Discussion and conclusion: The course reached a wide range of health care professionals in the region and improved neurosurgical knowledge, which should benefit patient care in this underserved region.

The use of intraoperative neurosurgical ultrasound for surgical navigation in low- and middle-income countries: the initial experience in Tanzania.

OBJECTIVE: Neuronavigation has become a crucial tool in the surgical management of CNS pathology in higher-income countries, but has yet to be implemented in most low- and middle-income countries (LMICs) due to cost constraints. In these resource-limited settings, neurosurgeons typically rely on their understanding of neuroanatomy and preoperative imaging to help guide them through a particular operation, making surgery more challenging for the surgeon and a higher risk for the patient. Alternatives to assist the surgeon improve the safety and efficacy of neurosurgery are important for the expansion of subspecialty neurosurgery in LMICs. A low-cost and efficacious alternative may be the use of intraoperative neurosurgical ultrasound. The authors analyze the preliminary results of the introduction of intraoperative ultrasound in an LMIC setting. METHODS: After a training program in intraoperative ultrasound including courses conducted in Dar es Salaam, Tanzania, and Aurora, Colorado, neurosurgeons at the Muhimbili Orthopaedic and Neurosurgical Institute began its independent use. The initial experience is reported from the first 24 prospective cases in which intraoperative ultrasound was used. When possible, ultrasound findings were recorded and compared with postoperative imaging findings in order to establish accuracy of intraoperative interpretation. RESULTS: Of 24 cases of intraoperative ultrasound that were reported, 29.2% were spine surgeries and 70.8% were cranial. The majority were tumor cases (95.8%). Lesions were identified through the dura mater in all 24 cases, with 20.8% requiring extension of craniotomy or laminectomy due to inadequate exposure. Postoperative imaging (typically CT) was only performed in 11 cases, but all 11 matched the findings on post-dural closure ultrasound. CONCLUSIONS: The use of intraoperative ultrasound, which is affordable and available locally, is changing neurosurgical care in Tanzania. Ultimately, expanding the use of intraoperative B-mode ultrasound in Tanzania and other LMICs may help improve neurosurgical care in these countries in an affordable manner.
