Objective To study the application effect of PDCA management mode in the teaching process of practice nurses in spine surgery to reduce the occurrence of nursing errors. Methods A total of 35 practice nurses in spine surgery from March 2014 to March 2015 received the routine teaching mode were set as control group, and 35 practice nurses from April 2015 to April 2016 implemented PDCA management mode were set as intervention group. The occurrence rate of nursing adverse events in two years was observed, and the interns for clinical teaching evaluation model of quality and satisfaction and the intern examination results were summarized. Results The incidence of nursing adverse events was 22.86% (8/35) in control group, and 2.86% (1/35) in intervention group, the difference was statistically significant (χ2= 17.85, P= 0.00). The intern teacher for clinical teaching content arrangement, teaching attitude, detail guidance and skills training indicators evaluation score were (15.46±1.03), (14.18±1.06), (14.61±1.11), (13.30±1.07) points in control group, and (18.26±1.00), (18.48±0.51), (19.43±0.21), (19.16±0.28) points in intervention group, the differences were statistically significant (t= 11.54-31.34, P < 0.01). The interns given theory and skills examination results were (80.15±1.61), (85.16±1.02) points in control group, and (93.10±2.01), (91.06±2.03) points in intervention group, the difference was statistically significant (t=29.75, 15.36, all P=0.00). The clinical teaching satisfaction was 57.14% (20/35) in control group, and 80.00% (28/35) in intervention group, the difference was statistically significant (χ2= 12.12, P=0.00). Conclusions PDCA management model applied to clinical practice in department of orthopedics teaching process, can effectively improve the intern theory knowledge and skills to master the ability, most of the interns examination results are more optimistic, and for this kind of management pattern for the process of teaching evaluation of higher satisfaction, the teachers care under the guidance of intern nursing mistake, nursing adverse events is low, this method is worthy of promotion.
