Brief summary

In the year of 2010, the Taiwan Ministry of Health and Welfare had implemented the 5-level Taiwan Triage and Acuity Scale(TTAS) in Taiwan emergency department. TTAS is a triage system that was modified from CTAS. It has a comprehensive chief complaint system and accomplished with an electronic decision support system (eTTAS) to help triage nurse to assign acuity level on emergency patients in emergency departments of Taiwan. TTAS has adult and children modifiers, but no modifier for the elderly. In emergency departments, the geriatric population have been increasing in many countries for the last few years. They often present with atypical symptoms or signs, and multiple comorbidities that complicate diagnosis and treatment and are at risk of under-triage. Although the TTAS has overall validity and reliability, its performance in geriatric patients has not been well studied. In order to reduce the chance to under-triage the geriatric patients in emergency departments and to improve the discriminatory and predictive power for triaged patients who require admission, the objective of the study is to examine the difference of urgency, admission rate and medical resource consumption of geriatric patients with different age group compared to non-geriatric patients, to develop predictive model for hospitalization and medical resource consumption among geriatric patients and to develop special geriatric modifiers.

Detailed description

Age and frailty have been demonstrated to be associated with clinical outcomes in the elderly presented to emergent departments (EDs). This study aimed to assess the association of age and frailty on admission rate and to find out whether the current Taiwan Triage and Acuity Scale (TTAS) under-triage elderly presented to EDs. This was a retrospective cohort study that reviewed medical records of adult patients from a single ED from 2016 to 2017. Data collected included patients' demographics, TTAS level, chief complaints, frailty status, and intensive care unit (ICU) admission rate. Adults patients included in the study were divided into three age groups of 18-\<65, 65-85, and \>85 years.
