Abuse of the Korean Triage and Acuity Scale in the assessment of emergency medical facilities

ABSTRACT

The Korean Triage and Acuity Scale (KTAS) is a localized modification of the Canadian Triage and Acuity Scale (CTAS). Although CTAS was not intended for defining the severity of individual patients or to be used in reimbursement processes, the misuse of KTAS is commonplace in Korea. In particular, the national assessment of emergency medical facilities in 2019 includes several indicators based on the improper application of KTAS scores.
