Abstract: To study the value of mini clinical evaluation exercise (Mini-CEX) in training respiratory residents, all 22 new respiratory residents of Shanghai Pulmonary Hospital were evaluated by Mini-CEX from July 2014 to July 2015. Each respiratory resident was evaluated for 6 times. The respiratory residents realized their weaknesses through Mini-CEX, and their clinical competence was improved by strengthening exercises. There was significant statistics difference between the first and the last Mini-CEX scores (P<0.01). Teachers’ and residents’ satisfaction rate with Mini-CEX was more than 90%. Mini-CEX is a convenient and effective medical teaching method. The implementation of Mini-CEX is benefitial to better development of the respiratory residents.
