Objective To investigate the effect of complication and treatment compliance on PDCA nursing pathway in children with bronchial pneumonia. Methods 126 children with bronchial pneumonia were divided into two groups by random number table. There were 67 children in observation group with PDCA nursing pathway and 59 children in control group with normal nursing pathway. The effects of nursing in two groups were observed, including complications, length of hospital stay, cost, nursing compliance and satisfaction of nursing. Results The total occurrence rate of complication in observation group was 4.5%(3/67), while in control group was 18.6%(11/59). There was significant difference between the two groups (χ2=6.375, P<0.05). Compliance rate of children in observation group was 62.7%(42/67) which was significantly higher than 44.1% (26/59) of control group (χ2=4.738, P < 0.05). Hospitalization time in observation group was (5.9±2.1) d and cost was (1 703±390) yuan, while those in control group were (6.9 ± 2.8) d and (2 012 ± 501) yuan respectively. Both in observation group were obviously lower than in control group, and the difference was significant (χ2=2.161, 3.668, P<0.05). The satisfaction of nursery in observation group was significantly higher than the control group, which were 82.1% (55/67) and 61.0% (36/59) respectively. The difference was significantly different (χ2=6.944,P <0.05). Conclusions PDCA nursing pathway could decrease complication and improve treatment compliance as well as satisfaction of patients, it′s worth popularizing.
