Barriers to neurotrauma care in low- to middle-income countries: an international survey of neurotrauma providers.

Objective: Delays along the neurosurgical care continuum are associated with poor outcomes and are significantly greater in low- to middle-income countries (LMICs), with timely access to neurotrauma care remaining one of the most significant unmet neurosurgical needs worldwide. Using Lancet Global Surgery metrics and the Three Delays framework, the authors of this study aimed to identify and characterize the most significant barriers to the delivery of neurotrauma care in LMICs from the perspective of local neurotrauma providers.

Methods: The authors conducted a cross-sectional study through the dissemination of a web-based survey to neurotrauma providers across all World Health Organization geographic regions. Responses were analyzed with descriptive statistics and Kruskal-Wallis testing, using World Bank data to provide estimates of populations at risk.

Results: Eighty-two (36.9%) of 222 neurosurgeons representing 47 countries participated in the survey. It was estimated that 3.9 billion people lack access to neurotrauma care within 2 hours. Nearly 3.4 billion were estimated to be at risk for impoverishing expenditure and 2.9 billion were at risk of catastrophic expenditure as a result of paying for care for neurotrauma injuries. Delays in seeking care were rated as slightly common (p < 0.001), those in reaching care were very common (p < 0.001), and those in receiving care were slightly common (p < 0.05). The most significant causes for delays were associated with reaching care, including geographic distance from a facility, lack of ambulance service, and lack of finances for travel. All three delays were correlated to income classification and geographic region.

Conclusions: While expanding the global neurosurgical workforce is of the utmost importance, the study data suggested that it may not be entirely sufficient in gaining access to care for the emergent neurosurgical patient. Significant income and region-specific variability exists with regard to barriers to accessing neurotrauma care. Highlighting these barriers and quantifying worldwide access to neurotrauma care using metrics from the Lancet Commission on Global Surgery provides essential insight for future initiatives aiming to strengthen global neurotrauma systems.
