Abstract: Objective To explore the establishment of an index system suitable for the assessment of neurosurgery specialists' standardized training completion. Methods The assessment indicators for neurosurgery specialists' standardized training completion was initially screened through literature research. A preliminary index system was established based on the Milestone system. Expert correspondence were carried out using the Delphi method to revise and score the assessment indicators. Results Two rounds of correspondence were conducted with 15 experts and 2 specialty physician standardized training administrators from three tertiary grade A comprehensive hospitals. After modification by experts, an assessment index system was ultimately formed. Six first-level indicators (professional ethics, knowledge and skills, lifelong learning, communication and cooperation, patient care, teaching and research), 18 second-level indicators, and 66 third-level indicators were included in this index system. The weights of each first-level indicator were determined to be professional ethics 16.62%, knowledge and skills 18.43%, lifelong learning 16.49%, communication and cooperation 16.66%, patient care 16.43%, and teaching and research 15.37%. The Cronbach's alpha coefficient of the expert correspondence was 0.985, and the content validity index was 0.940. Conclusions The constructed assessment index system for the completion of neurosurgery specialist standardized training was found to be scientifically and systematically reflective of the content that needs to be examined for the completion of standardized training for neurosurgery specialists and inform the assessment of standardized training completion for neurosurgery specialists.
