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.

Rhabdomyolysis associated with psychogenic polydipsia and hyponatremia is a rare condition that can cause substantial morbidity and mortality. We report a 14-year-old boy with psychogenic polydipsia who experienced recurrent hyponatremia and subsequent rhabdomyolysis. Treatment involved intravenous fluids and restriction of oral water intake. This case emphasizes the importance of early recognition and management of this condition. The possibility of rhabdomyolysis should be considered in patients with hyponatremia who have myalgia.

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.

Purpose: This study was performed to investigate the gender differences in suicide attempts in adolescents. Methods: We reviewed the medical records of adolescents (≤ 18 years) who had visited a university hospital emergency department (ED) for suicide attempts from January 2018 through December 2019. General characteristics of the adolescents, details of the attempt, and outcomes were analyzed. The characteristics were age, gender, the Korean Triage and Acuity Scale, previous attempts, and psychiatric history. The details were initial Glasgow Coma Scale, attempt-arrival time, living alone, method, place, and motivation of the attempt, and concurrent use of alcohol. The outcomes included psychiatric consultation, ED length of stay, and ED outcomes. Results: A total of 86 adolescents were included. Their age ranged from 13 to 18 years, and girls accounted for 65.1%. The girls had more frequent psychiatric history than boys (66.1% vs. 30.0%; P = 0.001) without a significant difference in previous attempts (55.4% vs. 46.7%; P = 0.442). The most common methods of the attempt in the girls and boys were poisoning and sharp objects (53.3% [16 of the 30 boys] vs. 60.7% [34 of the 56 girls]; P = 0.002), respectively. No differences were found in the other details of the attempt and in the rate of psychiatric consultation. The girls had longer ED length of stay (247.0 minutes vs. 186.5; P = 0.033), a lower rate of discharge against medical advice, and higher rates of hospitalization (discharge against medical advice, 53.6% vs. 76.7%; non-psychiatric, 23.2% vs. 3.3%; psychiatric, 12.5% vs. 0%; P = 0.003). Conclusion Girls may make suicide attempts, usually by poisoning, and undergo relevant hospitalization, more often than boys. In contrast, boys usually use sharp objects, with a higher rate of discharge against medical advice and lower rates of the attempt and hospitalization.

In recent years, artificial intelligence (AI) technologies have greatly advanced and become a reality in many areas of our daily lives. In the health care field, numerous efforts are being made to implement the AI technology for practical medical treatments. With the rapid developments in machine learning algorithms and improvements in hardware performances, the AI technology is expected to play an important role in effectively analyzing and utilizing extensive amounts of health and medical data. However, the AI technology has various unique characteristics that are different from the existing health care technologies. Subsequently, there are a number of areas that need to be supplemented within the current health care system for the AI to be utilized more effectively and frequently in health care. In addition, the number of medical practitioners and public that accept AI in the health care is still low;moreover, there are various concerns regarding the safety and reliability of AI technologyimplementations. Therefore, this paper aims to introduce the current research and application status of AI technology in health care and discuss the issues that need to be resolved.

OBJECTIVES: The aim of this study was to compare differences in perception and knowledge of child abuse and child disciplinary practices according to the history of child abuse victimization. METHODS: A questionnaire survey on child abuse was conducted with 491 adults raising children. We compared the perception and knowledge of child abuse and child disciplinary practices between two groups of adults with and without a history of childhood abuse victimization. RESULTS: The group with a history of childhood abuse had lower levels of knowledge of child abuse (F=6.990, p<0.01) and engaged in more negative disciplinary practices (F=5.974, p<0.05) than those without. However, no differences in the perception of child abuse were observed between the two groups. CONCLUSION: The results suggest that adults with a history of childhood abuse have lower levels of knowledge of child abuse and use more negative disciplinary practices in raising their children. This highlights the need to administer not only educational but also more direct hands-on interventions to vulnerable parents in order to foster healthy parenting and disciplinary practices.

OBJECTIVE: The use of computed tomography (CT) in pediatric patients has decreased since the association between radiation and cancer risk has been reported. However, in adolescent patients being treated as adult patients, there has been a high incidence of CT use in emergency departments (EDs). Thus, this study aimed to evaluate the CT use in adolescent patients with complaints of headache or abdominal pain in the general and pediatric EDs of the same hospital.METHODS: A retrospective chart review of patients aged 15 to 18 years, who presented with headache or abdominal pain at the general and pediatric EDs of Seoul National University Hospital from January 2010 to December 2014, was conducted.RESULTS: A total of 407 adolescent patients with complaints of headache and 980 with abdominal pain were included in this study. The adolescent patients in the general ED were more likely to undergo CT scans than those in the pediatric ED, with both patients having headache (42.4% vs. 20.5%, respectively, P<0.001) and abdominal pain (29.0% vs. 18.4%, respectively, P<0.001). There was no statistical difference in the rates of positive CT findings between the general and pediatric EDs. The frequency of visits to the general ED was associated with high rates of CT use in adolescent patients with complaints of headache (odds ratio, 3.95; 95% confidence interval, 2.01 to 7.77) and those with abdominal pain (odds ratio, 1.76; 95% confidence interval, 1.18 to 2.64).CONCLUSION: The ED setting influences the use of CT on adolescent patients, and a child-friendly environment could reduce the radiation risks.

OBJECTIVE: The aim of this study was to investigate the effectiveness of a quality improvement activity for pain management in patients with extremity injury in the emergency department (ED). METHODS: This was a retrospective interventional study. The patient group consisted of those at least 19 years of age who visited the ED and were diagnosed with International Classification of Diseases codes S40–S99 (extremity injuries). The quality improvement activity consisted of three measures: a survey regarding activities, education, and the triage nurse’s pain assessment, including change of pain documentation on electronic medical records. The intervention was conducted from January to April in 2014 and outcome was compared between May and August in 2013 and 2014. The primary outcome was the rate of analgesic prescription, and the secondary outcome was the time to analgesic prescription. RESULTS: A total of 1,739 patients were included, and 20.3% of 867 patients in the pre-intervention period, and 28.8% of 872 patients in the post-intervention period received analgesics (P < 0.001). The prescription rate of analgesics for moderate-to-severe injuries was 36.4% in 2013 and 44.5% in 2014 (P=0.026). The time to analgesics prescription was 116.6 minutes (standard deviation 225.6) in 2013 and 64 minutes (standard deviation 75.5) in 2014 for all extremity injuries. The pain scoring increased from 1.4% to 51.6%. CONCLUSION: ED-based quality improvement activities including education and change of pain score documentation can improve the rate of analgesic prescription and time to prescription for patients with extremity injury in the ED.

OBJECTIVE: Many studies have proposed reducing unnecessary use of computed tomography (CT), and ongoing studies in pediatric populations are aiming to decrease radiation dosages whenever possible. We aimed to evaluate the long-term changes in the utilization patterns of CT and ultrasound (US) in pediatric emergency departments (PEDs). METHODS: This retrospective study reviewed the electronic medical data of patients who underwent CT and/or US in the PED of a tertiary referral hospital from 2000 to 2014. We compared the changes in utilization patterns of brain and abdominal CT scans in pediatric patients and analyzed changes in abdominal US utilization in the PED. RESULTS: During the study period, 196,371 patients visited the PED. A total of 12,996 brain and abdominal CT scans and 12,424 abdominal US were performed in the PED. Comparison of CT use in pediatric patients before and after 2007 showed statistically decreasing trends after 2007, expressed as the coefficient values of the differences in groups. The numbers of brain and abdominal CT scans showed a significant decreasing trend in children, except for abdominal CT in adolescents. The abdominal US/CT ratio in the PED showed a statistically significant increase (2.68; 95% confidence interval, 1.87 to 3.49) except for the adolescent group (5.82; 95% confidence interval, -2.06 to 13.69). CONCLUSION: Overall, CT use in pediatric patients has decreased since 2007. Pediatric US use has also shown a decreasing trend; however, the abdominal US/CT ratio in pediatric patients showed an increasing trend, except for adolescents.
