Abstract

Background and Objectives Preoperative assessment is one of the most important fields in surgery and anesthesia as it can reduce morbidity and mortality from surgery and detect abnormal findings not clinically observed through preoperative examination. However, excessive non-vital preoperative routine tests have been criticized. The aim of the study is to investigate the current use of elective preoperative evaluations using otorhinolaryngologic surgery covering patients of all ages with various levels of difficulty. Subjects and Method Using the Korean National Health Insurance Service National Sample Cohort data, we investigated 98890 subjects who underwent otorhinolaryngologic surgery during the year 2018. We evaluated sociodemographic characteristics, clinical characteristics, medical institutions, and operation characteristics of the subjects and analyzed in detail their routine blood and urine test items, sonographic exams and pulmonary function tests. Results There were differences in the implementation of preoperative blood and urine tests, sonographic exams and pulmonary function tests according to sociodemographic characteristics, types and locations of medical institutions. Old age, low socioeconomic status, comorbid condition, high Charlson's Comorbidity Index, tertiary hospital were the factors that increased preoperative evaluation tests. Conclusion Appropriate preoperative evaluation is needed for predicting and preparing for the possibility of treatment complications as well as improving treatment quality while reducing costs for perioperative management. © 2022 Korean Society of Otorhinolaryngology-Head and Neck Surgery.
