Training needs assessment: tool utilization and global impact.

Overall evidence shows that the TNA survey is widely used as a clinical practice and educational quality improvement tool across continents. Translation, cultural adaptation, and psychometric testing within a variety of settings, populations, and countries consistently reveals training gaps and outcomes of targeted continuous professional development. Furthermore, it facilitates prioritization and allocation of limited educational resources based on the identified training needs. The TNA tool effectively addresses the "know-do" gap in global human resources for health by translating knowledge into action.
