Characteristics of patients transferred from long-term care hospital to emergency department

Objective@#This study was undertaken to assess the appropriateness of transfer of patients from a long-term care hospital to the emergency department (ED). @*Methods@#We conducted a retrospective study in a Wide Regional Emergency Center in Gyeongsangnam-do between January 2019 and December 2019. The patients were divided into groups (direct visit, transferred from other hospitals, and transferred from long-term care hospitals [LTCHs]). The baseline characteristics, Korean Triage and Acuity Scale (KTAS), vital signs, length of stay, ED disposition, cost, clinical outcome, and instances of application of the “Act on decisions on life-sustaining treatment” were collected. @*Results@#A total of 30,142 patients were enrolled during the study period. Twenty-one thousand, nine hundred and sixty-five patients were in the direct visit group, 7,057 patients were transferred from other hospitals, and 1,120 patients were transferred from LTCHs. Hospital admission was higher in cases of transfer from other hospitals and LTCHs (LTCHs, 63.8%; transferred from other hospitals, 64.1%, direct visit, 30.1%; P<0.001). Re-transfer and mortality in the ED were much higher (re-transfer: LTCHs, 11.0%; transferred from other hospitals 3.8%, direct visit 1.9%; P<0.001 and mortality in ED: 2.9%, 0.8%, 1.4%; respectively P<0.001). In the LCTH group after admission, mortality was higher (mortality: 16.2%, 5.4%, 7.1% for LTCH transfers and direct respectively; P<0.001). The implementation rate of the “Act on decisions on life-sustaining treatment”, the well-dying law, was higher in the LTCHs (26.6%, 12.5%, and 11.4% LTCH transfers, and direct respectively; P<0.001). @*Conclusion@#In the LTCH group, re-transfer, mortality, and the implementation rate of the “Act on decisions on life-sustaining treatment” were higher than in the other groups.

The influence of symptom to balloon time in ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention

OBJECTIVE@#The current guidelines for the treatment of ST-segment elevation myocardial infarction (STEMI) recommends early reperfusion with a door to balloon (DTB) time of 90 minutes or less in patients undergoing primary percutaneous coronary intervention (PPCI). Therefore, the focus of most studies has been the DTB time. On the other hand, the ischemic time is related to the symptom to balloon (STB) time rather than the DTB time. This study examined the clinical effects of the STB time as well as the social and clinical factors affecting the STB time in STEMI patients.@*METHODS@#This study analyzed 286 patients diagnosed with STEMI from December 2008 to December 2016. The STB time (≤4 hours and>4 hours, ≤12 hours, and >12 hours) in the groups was compared. The mortality and ejection fraction were investigated. In addition, the characteristics of patients and socioeconomic factors affecting STB were analyzed.@*RESULTS@#The SBT time is inversely associated with the ejection fraction (R=−0.126, P=0.033), and the ejection fraction of the ≤12 hours group was higher than that of the >12 hours group (54% vs. 50%, P=0.047). On the other hand, there was no significant difference in mortality between the two groups (3.26% vs. 4.84%, P=0.506). In multivariate analysis, the variable related to SBT was only typical chest pain (adjusted odd ratio, 1.931; 95% confidential interval, 1.014-3.792; P=0.045).@*CONCLUSION@#The results of the study support the prognostic value of SBT in STEMI undergoing PPCI. Therefore, efforts should be made to shorten the STB time.

Factors associated hospital admission in patients with low acuity visiting emergency department

OBJECTIVE: Patients with low acuity who need hospitalization may be at risk if they do not receive proper treatment in overcrowded emergency rooms. This study was conducted to investigate factors affecting the hospitalization of patients with low acuity of Korean Triage and Acuity Scale (KTAS). METHODS: This study was a retrospective chart review analysis of patients aged 15 years or older who had triaged as KTAS 4 and 5 grades when visiting a local emergency medical center from January 1, 2016 to December 31, 2017. Multivariate logistic analysis was performed to analyze the effects of age, sex, reasons for visiting, visiting route, ambulance utilization, KTAS grade and major category on patient admission. RESULTS: A total of 10,540 patients were enrolled and the odds ratio (OR) increased with age from those aged over 34 years (P < 0.001). Patients that triaged as KTAS grade 5 (adjusted OR, 1.57; 95% confidence interval [CI], 1.36–1.82), had a condition caused by disease (adjusted OR, 2.31; 95% CI, 2.00–2.68), and visited by using an ambulance (public: adjusted OR, 1.05; 95% CI, 0.91–1.22; private: adjusted OR, 4.60; 95% CI, 3.85–5.49) were more likely to be hospitalized. Individuals in the “general” major category were more likely to be hospitalized than those falling into other major categories (P < 0.001). CONCLUSION: The factors influencing the hospitalization of patients with low acuity were age, reasons for visiting, visiting route, ambulance utilization, KTAS grade and major category on patient admission.

Recombinant Activated Factor VII as a Second Line Treatment for Postpartum Hemorrhage / 대한구급학회지

BACKGROUND: Severe or massive postpartum hemorrhage (PPH) has remained a leading cause of maternal mortality for decades across the world and it results in critical obstetric complications. Recombinant activated factor VII (rFVIIa) has emerged as a gold standard adjunctive hemostatic agent for the treatment of life-threatening PPH refractory to conventional therapies although it remains off-licensed for use in PPH. We studied the effects of rFVIIa on coagulopathy, transfusion volume, prognosis, severity change in Korean PPH patients. METHODS: A retrospective review of medical records between December 2008 and March 2011 indicating use of rFVIIa in severe PPH was performed. We compared age, rFVIIa treatment, transfusion volume, and Sequential Organ Failure Assessment (SOFA) score at the time of arrival in the emergency department and after 24 hours for patients whose SOFA score was 8 points or higher. RESULTS: Fifteen women with SOFA score of 8 and above participated in this study and eight received rFVIIa administration whereas seven did not. Patients' mean age was 31.7 ± 7.5 years. There was no statistically significant difference in initial and post-24 hours SOFA scores between patients administered rFVIIa or not. The change in SOFA score between initial presentation and after 24 hours was significantly reduced after rFVIIa administration (P = 0.016). CONCLUSIONS: This analysis aimed to support that the administration of rFVIIa can reduce the severity of life-threatening PPH in patients. A rapid decision regarding the administration of rFVIIa is needed for a more favorable outcome in severe PPH patients for whom there is no effective standard treatment.

Validity of the Newly Developed Five Level Pediatric Triage System Implemented in a Children's Hospital Emergency Department

PURPOSE: Korean Acuity and Triage Scale (KTAS) has been used nationally since 2016 for triage in emergency departments. After the newly developed triage tool was applied, there have been few studies of the validity of pediatric KTAS. The purpose of this study was to evaluate the validity of KTAS in children under the age of 15 who visited a single children's hospital. METHODS: This retrospective study was conducted on 7,011 pediatric patients under the age of 15 who visited a single child hospital between January 1 and December 31, 2016, the difference in the admission rate, intensive care unit admission rate, length of stay in the emergency department, and total hospital cost in emergency department were analyzed using the KTAS level. RESULTS: The number of patients triaged as KTAS IV was highest with 48.2%. The length of stay was longest in KTAS I and shortest in KTAS V. The medical cost in emergency department was highest in KTAS I and lowest in KTAS V. All dependent variables except for the intensive care unit admission rate showed significant differences according to the KTAS level. CONCLUSION: When the KTAS of the newly developed five level triage system was applied to pediatric patients, there were statistically significant difference in hospitalization, length of stay in emergency department, and total cost to the emergency department according to the KTAS level. Therefore, it will be necessary to evaluate the validity of KTAS through multicenter studies including hospitals with various characteristics.

Feature of Visiting Patients to a Wide Regional Emergency Center According to Insurance Status

PURPOSE: In Korea, emergency department overcrowding in large hospitals have caused social concern. Moreover, patients with low socioeconomic status visit the emergency department more frequently. This kind of visitation also causes a burden on the national budget, but emergent patient should be treated in emergency department regardless of economic state. So, on establishment of policy about the patient with low socioeconomic status, the frequency of emergency visitation alone is difficult to obtain a sufficient basis for policy-making. METHODS: We retrospectively analyzed adult patients with a disease who visited the Pusan Wide-regional Emergency Center in 2015. Korean Triage and Acuity Scale level I, II or III were defined as emergency, and level IV or V was defined as non-emergency. The ratio of emergency and non-emergency was compared in the National Health Insurance and Medicaid database. RESULTS: The number of patients with National Health Insurance was 16,208 (90.3%) and with Medicaid was 1,737 (9.7%). Among those with National Health Insurance, there were 12,720 (78.5%) emergency cases and 3,488 (21.5%) non-emergency cases. Among those with Medicaid, 1,379 (79.4%) emergency cases and 358 (20.6%) non-emergency cases. Between National Health Insurance and Medicaid, there was no statistically significant difference in the ratio of emergency and non-emergency (p=0.380) CONCLUSION: Accessibility of emergency and non-emergency patients with National Health Insurance and Medicaid to Pusan Wide-regional Emergency Center was not different.
