Background: The World Health Organization predicts a striking rise in the burden of traumatic brain injury (TBI) burden in the next decades. A disproportionately large increase is predicted in low- and middle-income countries, which have brain injury rates 3 times higher than high-income countries. The aim of this study was to identify current TBI practices and treatment capacity in 3 low- and middle-income countries: Republic of Armenia, Georgia, and Republic of Moldova. Methods: After a national inventory of hospitals treating TBI, a situational analysis was conducted in the highest volume adult and pediatric hospital in each country. The situational analysis included key informant interviews with content analysis and a quantitative checklist of treatment resources. Results: All 3 countries follow international, national, and hospital protocols for TBI treatment, and the in-hospital management of patients with TBI is similar to international standards in all 3 countries. Although health care specialists were well trained, however, lack of proper equipment, a scant number of hospitals outside the capital region, lack of specialized personnel in regional areas, and lack of rehabilitation services were mentioned as difficulties in interviews from all 3 countries. Conclusions: Particular gaps were found in pre-hospital and rehabilitative care, as well as national leadership and data collection. Surveillance and standardized data collection are important measures to fill treatment gaps and reduce the burden of TBI.
