A Comparative Study on the Process of Hospital Visits according to the Characteristics of the Elderly Visiting to Emergency Medical Centers

Factors associated with the undertriage of patients with abdominal pain in an emergency room

INTRODUCTION

The triage process lasts for a very short time, which can result in over-triage and under-triage. Studies have explored factors related to under-triage among trauma patients. In Korea, the clinical characteristics and severity of cases of under-triaged patients have been investigated. However, there is limited research on the under-triage of patients experiencing abdominal pain. Therefore, this study aimed to determine the under-triage rate of emergency department (ED) patients with abdominal pain, as well as the factors associated with their under-triage.

METHODS

The participants of this retrospective cohort study were 3,030 adult patients at a single tertiary hospital in Korea, who were brought to the ED for abdominal pain as the chief complaint. Participants' general characteristics, pain-related information, and environmental information were obtained from their electronic medical records.

RESULTS

The under-triage rate of ED patients with abdominal pain was 31.0%. Factors related to the under-triage of these patients were sex, age, visit route, time from the onset of the pain to the visit, location of pain, and intensity of pain.

CONCLUSION

These findings provide a foundation for the understanding and mitigation of under-triage in EDs through the identification of factors associated with under-triage in patients with abdominal pain.

Epidemiology of drug hypersensitivity reactions using 6-year national health insurance claim data from Korea

Background Drug hypersensitivity reactions (DHRs) constitute a large portion of adverse drug reactions (ADRs), but studies for DHR incidence based on national data are scarce. Objective This study aimed to estimate the incidence and patterns of DHRs in a Korean population and the associated utilization of medical resources using the national claims data. Setting The retrospective cohort study performed using the national insurance claim database of the Health Insurance Review and Assessment (HIRA) in Korea. Methods The International Classification of Disease 10th revision code was used to identify DHRs with 20 drug induced DHR codes. The claim data with a diagnosis of DHR in the 2009-2014 periods were analyzed. Main outcome and measure The annual incidence and the 6-year incidence rates were calculated. Incidence rate coefficients were analyzed by sex, age, and year. DHRs following with visits of emergency department (ED) or intensive care unit (ICU) were assessed for utilization of medical resources and risk of ER or ICU visits by sex and age Results A total of 535,049 patients with 1,083,507 claims were assessed in the HIRA database for 6 years. DHR incidence was high in the elderly. The risk of ED and ICU visit with DHR was also higher in the elderly than in the young [highest relative risk, RR of ED 2.59 (1.65-4.07), ICU 5.04 (2.50-10.18)]. DHRs related to blood were high in the young age. Conclusion Incidence of DHRs in the real-world clinical practice was higher in the elderly and female. Clinical consequence was more severe in the elderly.
