Objective To understand the current status of information management in standardized residency training bases in Guangdong Province, and to provide a basis for the standardized residency training. Methods From April to July 2023, a questionnaire survey was used to investigate the current status of the information management function of residents in 61 residency training bases in Guangdong Province. Descriptive statistics and correlation analysis were used to analyze the results. Results The information system coverage rate of residency training bases in Guangdong Province was 98.4% (60/61). The overall functional score for the information management of residents across the 60 residency training bases was (63.18±11.64), with an average score of (59.71±12.22) for various subdivided functions. Among them, subdivided functions such as admission and admission education scored higher (76.45±24.10), while communication and feedback scored lower (38.70±30.84). The overall functional score for the information management of residents and the score for rotation management positively correlated with the pass rate of the residents' final assessment (r=0.33 and 0.37, both P<0.05). Conclusions The level of information management of residents depends on the degree of attention and investment of the residency training base, and the degree of attention given to the management of residency training under the guidance of the information system determines the quality of the training of residents. The study of information system construction standards can help residency training bases with a relatively weak foundation quickly realize the need of improvement in management system and training quality. The establishment of a provincial residency information management platform can promote high-quality development of residency training in the region.
