Objective　To observe the effectiveness of mini-clinical evaluation exercise (Mini-CEX) on the standardized training of residents in the department of nephrology. Methods　Mini-CEX was used to evaluate the 80 residents who received clinical standardized training in the department of nephrology from March 2017 to March 2018 in our hospital. The assessment mainly contained seven aspects: medical history taking

physical examination

clinical diagnosis

therapeutic regimen

doctor-patient communication

humanistic care

and overall clinical ability. Meanwhile

a Mini-CEX questionnaire was conducted among 9 teachers and 80 residents

including their viewpiont and satisfaction degree on Mini-CEX. The SPSS 21.0 was used for statistical analysis and the independent sample t-test was used for comparison between the two groups. Results　Through the Mini-CEX assessment

every aspect of clinical competence of residents at the end of this program was significantly higher than that at the early period

and the difference was statistically significant (P<0.05). The most obvious improvement in residents was their treatment plan

overall clinical ability and physical examination. About the assessment of therapeutic regimen

the average score at the end of the training was (7.525±1.062)

which was better than before (5.175±1.035)

and the difference was statistically significant (P=0.000). Besides

clinical diagnosis and humanistic care were significantly better than those at the beginning (P<0.05). About the assessment of clinical diagnosis

the average score after the training was (6.925±1.071)

which was better than before (5.425±1.238)

and the difference was statistically significant (P=0.000). According to results of Mini-CEX questionnaire

teachers thought that Mini-CEX was a better way of assessment (88.9%) and could promote self-learning (77.8%)

while residents believed that Mini-CEX was close to clinical practice and the ward-or-practice-based assessment was relatively comprehensive

which could significantly improve clinical skills (85.0%) and comprehensive quality (87.5%)

with a satisfaction degree of 92.5%. Conclusion　Mini-CEX is applied in the standardized training of residents in the department of nephrology

which can effectively improve clinical comprehensive ability of residents and improve Self-learning of teachers.
