Abstract: To improve the quality of rotation examinations of standardized training for residents, Zhongnan Hospital of Wuhan University adopted PDCA cycle based reform. This paper analyzed its effect. The compliance rate of rotation examinations, the quality of the proposition, the scores of Annual Business Level Test before and after adopting PDCA cycle based reform were statistically analyzed by t-test, rank sum test or χ² test. Post and pre- PDCA cycle based reform, the compliance rates of rotation examinations were 90.1% and 64.2%, the difficulty of theoretical exam were [0.69 (0.61, 0.74)] and [0.81 (0.70, 0.89)], the differentiation of theoretical exam were (0.35±0.10) and (0.32±0.09), the differentiation of skill exam were(0.28±0.07) and (0.26±0.06), the differentiation of comprehensive exam were (0.32±0.09)and (0.28±0.08), the scores of Annual Business Level Test were(95.3±12.5) and (89.3±13.3), respectively, and there were statistical differences (all P<0.05). Pre- and post PDCA cycle based reform, the difficulty of skill exam were [0.85 (0.81, 0.95)] and [0.80 (0.66, 0.84)], the difficulty of comprehensive exam were [0.86 (0.79, 0.96)] and [0.81 (0.72, 0.88)], respectively, and there were no statistical differences (all P>0.05). PDCA cycle based reform can effectively improve the quality of rotation examinations, which improves the quality of standardized training for residents.
