The Duke Division of Global Neurosurgery and Neurology (DGNN) was established to address these inequities by building sustainable neurosurgical capacity through strategic partnerships, training programs, and service initiatives. DGNN's framework evolved from the initial \"3-Ts\" approach-technology, twinning, and training-to a broader focus on service, research, and training, prioritizing local ownership of neurosurgical systems. Key challenges, such as resource limitations, cross-cultural collaboration, and the retention of trained professionals, were overcome through collaborative efforts and a commitment to capacity building. The introduction of digitized health records and data systems, along with research projects in epilepsy and traumatic brain injury, contributed to a comprehensive model of growth. Through these initiatives, DGNN has expanded neurosurgical services and increased the number of trained neurosurgeons in Uganda, creating a sustainable model that can be adapted to other countries.

Most patients were managed without neurosurgical operative intervention, with subsequent neurosurgical interventions linked to a higher mortality rate (HR 6.08, p < 0.001). The inpatient mortality rate was 29.3%, mainly from severe TBIs (69%). Patients needing intracranial pressure monitoring had higher inpatient mortality (p < 0.001).
