Purpose To evaluate the efficiency of the pediatric emergency ward (PEW) through the outcomes of children hospitalized to the ward by the department of pediatric emergency medicine (PEM). Methods A chart review was completed for children (< 15 years) who were hospitalized to the PEW via the pediatric emergency center from March through May 2021. We compared the general characteristics and details regarding the outcomes depending on the departments they were hospitalized to, namely PEM, pediatrics (PED), and others. Results We analyzed a total of 606 hospitalized children: PEM, 91; PED, 456; and others, 59. In the order listed above, their median ages were 2 years (interquartile range, 1-6), 1 year (0-4), and 9 years (7-14) (P < 0.001). The numbers of children with Korean Triage and Acuity Scale of 1-3 were 71 (78.0%), 400 (87.7%), and 33 (55.9%) (P < 0.001). Median length of stay (LOS) in the emergency department (ED) and hospital tended to be shorter in PEM (ED LOS: PEM, 4.3 hours vs. PED and others, 4.0-6.3 hours; hospital LOS: PEM, 19.0 hours vs. PED and others, 58.5-63.8 hours; all Ps < 0.001). The differences in the LOS were prominent between others and PEM (ED LOS, 1.538 [95% confidence interval, 1.353-1.749]; hospital LOS, 3.375 [2.741-4.157]). Transfers to other departments occurred only in PEM (4.4%) and PED (3.9%) whereas intensive care was performed only in others (27.1%). Return visits showed no difference among the 3 departments. Top 5 chief complaints and primary diagnoses of the children hospitalized to PEM were vomiting, fever, abdominal pain, head injury, and poisoning, and gastroenteritis, concussion, syncope, poisoning, and upper respiratory infection, respectively. Conclusion Hospitalization to PEWs for short-term treatment or observation may relieve overcrowding in EDs or in hospitals, with comparable frequency of return visits.

Purpose The authors aimed to investigate the utility of blood culture (BC) for children with simple febrile seizure (SFS) in the emergency department (ED) in the post-10/13-valent pneumococcal conjugate vaccine (PCV) era. Methods This study was performed at the ED of a tertiary care university-affiliated women and children’s hospital, and involved 3,237 previously healthy children aged 6-60 months who visited the ED with SFS from January 2013 through December 2017. The SFS was defined according to the International Classification of Diseases, 11th Revision codes related to seizure. The children were divided into 2 groups according to the vaccination rates of the period of their visit: the 70-PCV (70%, 2013-2014) and 97-PCV (97%, 2015-2017) groups. The primary outcome was the yield, defined as a true positivity of BC. In addition, we collected information on baseline characteristics, ED length of stay, inflammatory biomarkers, and ED outcomes. Results Of the 1,578 children with SFS who underwent BC, 1,357 belonged to the 97-PCV group. The median age of the study population was 22 months (interquartile range, 16.0-30.0), and 935 children (59.3%) were boys. Of the 41 children (2.6%) with positive BC results, 3 had the yield (0.2%): Staphylococcus aureus in 2 children and Streptococcus pneumoniae in the other. All 3 children belonged to the 97-PCV group. There were 38 contaminated BCs (2.4%; 95% confidence interval, 1.6%-3.2%). The 97-PCV group showed a shorter median ED length of stay (166.0 minutes [108.0-279.5] vs. 143.0 [109.5-209.5]; P = 0.010) and a lower rate of hospitalization (39.4% vs. 12.8%; P < 0.001). No differences between the 2 groups were found in the baseline characteristics and biomarkers. Conclusion This study suggests a low utility of BC in previously healthy children with SFS in emergency settings in the post-10/13-valent PCV era.
