Application of clinical pathway using electronic medical record system in pediatric patients with supracondylar fracture of the humerus: a before and after comparative study

Background This study was performed to investigate the usefulness of clinical pathway (CP) using an electronic medical record (EMR) in pediatric patients undergoing closed pinning for supracondylar fracture of the humerus, by analyzing the length of hospital stay, hospital cost and satisfaction of the medical teams. Methods This before and after comparative study included consecutive children who underwent closed pinning for supracondylar fracture of the humerus since 2009. The pre-CP group consists of 90 patients with the mean age of 5.7 years, and the post-CP group consists of 32 patients with the mean age of 6.2 years. Multidisciplinary work-team developed CP using an EMR system in March 2011. The length of hospital stay was the primary outcome variable, and hospital cost and medical team’s satisfaction score were secondary outcome variables. The non-inferiority test was used to demonstrate the efficiency of the pathway. Results The length of hospital stay decreased from 2.9 ± 0.7 days to 2.4 ± 0.7 days by 15.0%, after the implementation of CP, and the lower bound of the 95% CI of the difference (0.14 day) was within the non-inferiority margin of −0.3 days. The hospital cost decreased from 1162.2 ± 236.7 US$ to 1139.8 ± 291.1 US$ by 1.9% and the lower bound of the 95% CI of the difference was −81.3 US$, which did not exceed the non-inferiority margin of −116.2 US$. Therefore, the post-CP group was not inferior compared with the pre-CP group in term of the length of hospital stay and total hospital cost. There was significant increase in the satisfaction score for doctors after implementation of CP (p < 0.001), but, no change in the satisfaction score for nursing staffs (p = 0.793). Conclusions The development and implementation of CP, using an EMR, in pediatric patients undergoing closed pinning for supracondylar fracture of the humerus enhances the treatment efficiency by streamlining the treatment process with no increases of the length of the hospital stay and total hospital costs.
