ObjectivesTo analyze the resident achievement assessment data of West China Hospital of Sichuan University in 2017, so as to provide experience for further realization of homogeneity in residency training.MethodsWe extracted the 381 residents' achievement assessment data of West China Hospital of Sichuan University in 2017, and compared data in the theory, skills and the overall passing scores of residents with different status types and different academic levels through χ2 test.ResultsThe results of the theory test (χ2=1.384 9, P=0.709 1), skills test (χ2=3.363 1, P=0.339 0), overall assessment (χ2=4.274 7, P=0.233 3) showed no statistically significant difference in residents with different status. The result of the theory test (χ2=0.417 5, P=0.811 6), skills test (χ2=0.461 4, P=0.794 0) and the overall assessment (χ2=0.680 0, P=0.711 8) showed no statistically significant differences in residents with different academic levels.ConclusionsIt can be concluded that the residency training in West China Hospital of Sichuan University has achieved homogeneity.
