Purpose: The study aims to assess the inter-rater reliability of the Korean Triage and Acuity Scale between the research nurses and the triage nurses. Methods: Interrater reliability was measured on 400 adult (≧15) and 400 pediatric (<15) patients who visited the emergency medical center from January 4 to June 30, 2018. Results: The study result showed that the inter-rater reliability of the Korean Triage and Acuity Scale was substantial, with κ=.73 (95% Confidence interval= .68-.78) and 77.0 percent agreement. The inter-rater of Pediatric Korean Triage and Acuity Scale was also substantial, with κ=.76 (95% Confidence interval= .71-.82) and 83.8 percent agreement. Conclusion: Although the inter-rater reliability of the Korean Triage and Acuity Scale was acceptable, the percent agreement was lower than the desirable level (<80.0%). It was confirmed that Pediatric Korean Triage and Acuity Scale had an acceptable level of inter-rater reliability and percent agreement for clinical use. Efforts should be made to improve the reliability in the future.

Objectives : To evaluate the predictive validity of three scoring systems; the acute physiology and chronic health evaluation(APACHE) III, simplified acute physiology score(SAPS) II, and mortality probability model(MPM) II systems in critically ill patients. Methods : A concurrent and retrospective study conducted by collecting data on consecutive patients admitted to the intensive care unit(ICU) including surgical, medical and coronary care unit between January 1, 2004, and March 31, 2004. Data were collected on 348 patients consecutively admitted to the ICU(aged 16 years or older, no transfer, ICU stay at least 8 hours). Three models were analyzed using logistic regression. Discrimination was assessed using receiver operating characteristic(ROC) curves, sensitivity, specificity, and correct classification rate. Calibration was assessed using the Lemeshow-Hosmer goodness of fit H-statistic. Results : For the APACHE III, SAPS II and MPM II systems, the area under the receiver operating characterist ic(ROC) curves were 0.981, 0.978, and 0.941 respectively. With a predicted risk of 0.5, the sensitivities for the APACHE III, SAPS II, and MPM II systems were 81.1, 79.2 and 71.7%, the specificities 98.3, 98.6, and 98.3%, and the correct classification rates 95.7, 95.7, and 94.3%, respectively. The SAPS II and APACHE III systems showed good calibrations(chi-squared H=2.5838 p=0.9577 for SAPS II, and chi-squared H=4.3761 p=0.8217 for APACHE III). Conclusions : The APACHE III and SAPS II systems have excellent powers of mortality prediction, and calibration, and can be useful tools for the quality assessment of intensive care units(ICUs).

The purpose of the present study was to assess the agreement of survival probability estimated by International Classification of Diseases l0th Edition(ICD-10) based International Classification of Diseases based Injury Severity Score(ICISS) with professional panel's judgment on preventable death. ICISS has a promise as an alternative to Trauma and Injury Severity Score(TRISS) which have served as a standard measure of trauma severity, but requires more validation studies. Furthermore as original version of ICISS was based ICD-9CM, it is necessary to test its performance employing ICD-10 which has been used in Korea and is expected to replace ICD-9 in many countries sooner or later. Methods : For 1997 and 1998 131 trauma deaths and 1,785 blunt trauma inpatients from 6 emergency medical centers were randomly sampled and reviewed. Trauma deaths were reviewed by professional panels with hospital records and survival probability of trauma inpatients was assessed using ICD-10 based ICISS. For trauma mortality degree of agreement between ICISS survival probability with judgment of professional panel on preventable death was assessed and correlation between W-score and preventable death rate by each emergency medical center was assessed. Results : Overall agreement rate of ICISS survival probability with preventable death judged by professional panel was 66.4%(kappa statistic 0.36). Spearman's correlation coefficient between W-score and preventable death rate by each emergency medical center was -0.77(p=0.07) and Pearson's correlation coefficient between them was -0.90(p=0.01). Conclusions : The agreement rate of ICD-10 based ICISS survival probability with of professional panel's judgment on preventable death was similar to TRISS. The W-scores of emergency medical centers derived from ICD-10 based ICISS were highly correlated with preventable death rates of them with marginal statistical significance.

The tools that classify the severity of patients based on the prediction of mortality include APACHE, SAPS, and MPM. Theses tools rely crucially on the evaluation of patients' general clinical status on the first date of their admission to ICU. Nursing activities are one of the most crucial factors influencing on the quality of treatment that patients receive and one of the contributing factors for their prognosis and safety. The purpose of this study was to identify the goodness-of-fit of CPSCS of critical patient severity classification system(CPSCS) and Glasgow coma scale(GCS) and the clinical usefulness of its death rate prediction. Data were collected from the medical records of 187 neurological patients who were admitted to the ICU of C University Hospital. The data were analyzed through $x^2$ test, t-test, Mann-Whitney, Kruskal-Wallis, goodness-of-fit test, and ROC curve. In accordance with patients' general and clinical characteristics, patient mortality turned out to be statistically different depending on ICU stay, endotracheal intubation, central venous catheter, and severity by CPSCS. Homer-Lemeshow goodness-of-fit tests were CPSCS and GCS and the results of the discrimination test using the ROC curve were $CPSCS_0$, .734, $GCS_0$,.583, $CPSCS_{24}$,.734, $GCS_{24}$, .612, $CPSCS_{48}$,.591, $GCS_{48}$,.646, $CPSCS_{72}$,.622, and $GCS_{72}$,.623. Logistic regression analysis showed that each point on the CPSCS score signifies1.034 higher likelihood of dying. Applied to neurologically ill patients, early CPSCS scores can be regarded as a useful tool.

Purpose: This study was a prospective survey to evaluate the Korean Triage and Acuity Scale (KTAS) inter-rater reliability and to identify discordant areas in the KTAS classification between nurses and paramedics in emergency department (ED). Methods: Inter-rater reliability were evaluated using triage deta from January 11 to May 31, 2019. A convinience sample of a total of 800 patients who visited an emergnecy medical center in Incheon (400 adult and 400 pediatric patients in this study) were selected. The triages of this study a pair of one nurse and one paramedic performed triage at the same time, using the KTAS, Inter-rater reliability for the KTAS was evaluated with the weighted kappa. Results: The inter-rater reliability of the KTAS evaluated by weighted Kappa between nurse-paramedic KTAS score of adult patients was .71, and .66 for pediatric patients. Both were in the level considered as substantial. Among causes of triage discordance, the most frequently identified discordant item in triaging adults was the difference in the measurement of pain intensity (28.0%). For both adult and pediatric patients, multiple chief complaint was identified as the major discordant factor. In triaging pediatric patients the body temperature assessment by subjective judgments was the highest discordant item (50.7%). Conclusion: The study result suggested that the KTAS demonstrated a reasonable level of inter-rater reliability and functioned as a standardized triage tool for emergency medical services. In order to improve the inter-rater reliability and classification competence, it is necessary to revise the current all-integrated KTAS provider course to be differentiated for each job group.

Purpose: The aim of this study was to identify the predictive validity of the Korean Triage and Acuity Scale (KTAS). Methods: This methodological study used data from National Emergency Department Information System for 2016. The KTAS disposition and emergency treatment results for emergency patients aged 15 years and older were analyzed to evaluate its predictive validity through its sensitivity, specificity, positive predictive value, and negative predictive value. Results: In case of death in the emergency department, or where the intensive care unit admission was considered an emergency, the sensitivity, specificity, positive predictive value, and negative predictive value of the KTAS were 0.916, 0.581, 0.097, and 0.993, respectively. In case of death in the emergency department, or where the intensive or non-intensive care unit admission was considered an emergency, the sensitivity, specificity, and positive predictive value, and negative predictive value were 0.700, 0.642, 0.391, and 0.867, respectively. Conclusion: The results of this study showed that the KTAS had high sensitivity but low specificity. It is necessary to constantly review and revise the KTAS level classification because it still results in a few errors of under and over-triage. Nevertheless, this study is meaningful in that it was an evaluation of the KTAS for the total cases of adult patients who sought help at regional and local emergency medical centers in 2016.
