BACKGROUND: This study was designed to analyze the influences of ICU patients' experiences in the ICU setting and the effect of ICU patient families' stress derived from their needs and daily life stress on the patients' quality of life. METHODS: ICU patients' quality of life was evaluated with KQOLS surveying 144 patients alive. The data was classified into 2 groups according to severity of illness and analyzed with an ANOVA. With a t-test, comparative analysis was made to examine deficiency of responses on patient families' needs and patients' quality of life. RESULTS: The patients in the group of higher severity of illness showed lower quality of life. The APACHEII score had a negative correlation with all domains except health status change domain, health status perception domain, and spiritual domain. There was a negative correlation between patients' age and three domains of physical function, role limitation, and social function and a positive correlation between patients' hospital LOS and health status change domain. The families in the group of lower severity of illness showed higher level of deficiency of responses on their needs for medical treatment and nursing information, and emotional support. Also, patients' quality of life in lower daily life stress group was higher than that in higher stress group especially in psychological health domain. CONCLUSIONS: The findings show that ICU patients `quality of life was influenced by not only medical factors but also psychosocial factors and suggest that multidimensional intervention plans are required for improving patients' quality of life and recovering their health.

PURPOSE: This study aimed to identify multidimensional factors influencing burnout in intensive care unit(ICU) nurses. METHODS: A descriptive cross-sectional design was used. Data were collected during February 2016 from a convenience sample of 222 tertiary hospital ICU nurses and analyzed using t-test, ANOVA, correlation analysis, and multiple regression analysis. RESULTS: Burnout correlated positively with compassion fatigue (CF)(r=.37, p < .001), and negatively with compassion satisfaction (CS)(r=-.66, p < .001). The regression model explained 57% of the variance in burnout. For individual characteristics in the model, perceived health status (β=-.27, p < .001) and gender (β=.14, p=.028) were the most influential factors for ICU nurses' burnout. In the model with added work-related characteristics, nursing environment (β=-.22, p=.001), perceived health status (β=-.20, p=.001), and satisfaction with department (β=-.19, p=.007) were the most influential factors. Finally, for the model with psychological characteristics added, CS (β=-.56, p < .001) and CF (β=.35, p < .001) were the most influential factors. CONCLUSION: Results reveal that most ICU nurses have a moderate level of CF and a moderate to high level of CS and burnout, and that individual, work-related and psychological factors are relevant in ICU nurses' burnout. Programs or interventions to reduce burnout should be developed taking into account these multidimensional factors.

BACKGROUND: This study was conducted to compare two models of the pediatric logistic organ dysfunction (PELOD) score and the pediatric index of mortality (PIM) 2 score in the emergency department (ED) and intensive care unit (ICU). METHODS: 90 pediatric patients who were admitted to the ICU in ED from January 2003 to December 2008 were enrolled in this study. PELOD score and PIM 2 score calculations were performed in the ED and ICU. We classified these patients into either the survivor or non-survivor groups and analyzed the clinical variables between two groups. We used Hosmer-Lemeshow goodness-of-fit tests to evaluate calibration, receiver operating characteristic (ROC) curves and standardized mortality ratio (SMR). RESULTS: Among the 90 pediatric patients, 56 (62.2%) were male, and 9 (10.0%) patients died. Expected mortalities were PIM 2 = 10.35, PELOD = 8.33 in ED and PIM 2 = 8.84, PELOD = 8.26 in ICU. PIM 2 showed fit calibration (x(2) = 6.228, p = 0.622) in the ED. In the ICU, both PELOD and PIM 2 showed calibration (x(2) = 4.625, p = 0.185) and (x(2) = 7.616, p = 0.472), respectively. PIM 2 in ED showed the best discrimination, with area under the curve (AUC) = 0.949 (95% CI, 0.881-0.984). CONCLUSIONS: PIM 2 score in ED was fit. Also, PELOD and PIM 2 score in ICU was fit. But PELOD in ED was unfit.

INTRODUCTIONThis study aims to determine the attitudes of Asian elderly patients towards invasive life support measures, the degree of patient-surrogate concordance in end-of-life decision making, the extent to which patients desire autonomy over end-of-life medical decisions, the reasons behind patients' and surrogates' decisions, and the main factors influencing patients' and surrogates' decision-making processes. We hypothesize that there is significant patient-surrogate discordance in end-of-life decision making in our community.

MATERIALS AND METHODSThe patient and surrogate were presented with a hypothetical scenario in which the patient experienced gradual functional decline in the community before being admitted for life-threatening pneumonia. It was explained that the outcome was likely to be poor even with intensive care and each patient-surrogate pair was subsequently interviewed separately on their opinions of extraordinary life support using a standardised questionnaire. Both parties were blinded to each other's replies.

RESULTSIn total, 30 patients and their surrogate decision-makers were interviewed. Twenty-eight (93.3%) patients and 20 (66.7%) surrogates rejected intensive care. Patient-surrogate concurrence was found in 20 pairs (66.7%). Twenty-four (80.0%) patients desired autonomy over their decision. The patients' and surrogates' top reasons for rejecting intensive treatment were treatment-related discomfort, poor prognosis and financial cost. Surrogates' top reasons for selecting intensive treatment were the hope of recovery, the need to complete final tasks and the sanctity of life.

CONCLUSIONThe majority of patients desire autonomy over critical care issues. Relying on the surrogates' decisions to initiate treatment may result in treatment against patients' wishes in up to one-third of critically ill elderly patients.

PURPOSE: The purpose of this study was to evaluate the clinical usefulness of the Critical Patient Severity Classification System (CPSCS) and Glasgow Coma Scale (GCS) for critically ill neurological patients and to determine the applicability of CPSCS and GCS in predicting their mortality. METHODS: Data were collected from the medical records of 187 neurological patients who were admitted to the intensive care unit of C university hospital. The datawere analyzed through chi-square test, t test,Mann-Whitney, Kruskal-Wallis, goodness-of-fit test, and receiver operating characteristic curve. RESULTS: In accordance with patients' general and clinical characteristics, patient mortality turned out to be significantly different depending on intensive care unit stay, endotracheal intubation, central venous catheter, and severity by CPSCS. Hosmer-Lemeshow goodness-of-fit tests were applied to CPSCS and GCS. The results of the discrimination test using the receiver operating characteristic curve were CPSCS0, .743, GCS0 .583, CPSCS24, .734, GCS24 .612, CPSCS48, .591, GCS48 .646, CPSCS72, .622, and GCS72 .623. Logistic regression analysis showed that each point on the CPSCS score signifies a 1.034 higher likelihood of dying. CONCLUSION: Applied to neurologically ill patients, early CPSCS scores can be regarded as a useful tool.

BACKGROUND: The ability to accurately adjust for the severity of illness in outcome studies of critically ill patients is essential for clinical audits and trials. Several studies have been carried out to validate the acute physiology and chronic health evaluation (APACHE II) score in Korean ICUs. However, few reports have been presented that compare the performance of the APACHE II score and diagnostic category weighted APACHE II models in the surgical ICU population of Korea. The aim of this study was to validate APACHE II and compare the performance of the APACHE II and adjusted APACHE II models for emergency admission in a surgical intensive care unit (SICU) population. METHODS: A retrospective analysis of the prospective ICU registry was conducted in the SICU between October 2007 and February 2011. Calibration and discrimination were determined by the Hosmer-Lemeshow test and the area under the receiver operating characteristic (AUC) curve from patients. RESULTS: This study included 854 patients. SICU mortality was 9.4%. For APACHE II and adjusted APACHE II, AUCs were 0.791 and 0.757, respectively. Hosmer and Lemeshow C statistics showed good calibration for APAHCE II and for adjusted APACHE II (p > 0.05). CONCLUSIONS: The ability of the APACHE II system in predicting group outcome is validated in a surgical ICU population by a receiver operating characteristic curve and logistic regression analysis. Mortality rates predicted using APACHE II exhibited good calibration and moderate discrimination. Diagnostic category weighted adjusted APACHE II did not improve the mortality prediction.

PURPOSE: Despite improved quality of intensive care, acute respiratory distress syndrome (ARDS) significantly contributes to mortality in critically ill children. As pre-existing definitions of ARDS were adult-oriented standards, the Pediatric Acute Lung Injury Consensus Conference (PALICC) group released a new definition of pediatric ARDS. In this study, we aimed to assess the performance of PALICC definition for ARDS risk stratification. METHODS: Total 332 patients who admitted to the intensive care unit at Severance Hospital from January 2009 to December 2016 and diagnosed as having ARDS by either the PALICC definition or the Berlin definition were retrospectively analyzed. Patient characteristics and mortality rates were compared between the individual severity groups according to both definitions. RESULTS: The overall mortality rate was 36.1%. The mortality rate increased across the severity classes according to both definitions (26% in mild, 37% in moderate and 68% in severe by the PALICC definition [P<0.001]; 20% in mild, 32% in moderate and 64% in severe by the Berlin definition [P<0.001]). The mortality risk increased only for severe ARDS in both definitions (hazard ratio [95% confidence interval]: 2.279 [1.414–3.672], P=0.001 by the PALICC definition; 2.674 [1.518–4.712], P=0.001 by the Berlin definition). There was no significant difference in mortality discrimination between the 2 definitions (difference in integrated area under the curve: 0.017 [−0.018 to 0.049]). CONCLUSION: The PALICC definition demonstrated similar discrimination power on PARDS' severity and mortality as the Berlin definition.

To compare mortality rate, the adjustment of case-mix variables is needed. The Pediatric Index of Mortality (PIM) 3 score is a widely used case-mix adjustment system of a pediatric intensive care unit (ICU), but there has been no validation study of it in Korea. We aim to validate the PIM3 in a Korean pediatric ICU, and extend the validation of the score from those aged 0–16 to 0–18 years, as patients aged 16–18 years are admitted to pediatric ICU in Korea. A retrospective cohort study of 1,710 patients was conducted in a tertiary pediatric ICU. To validate the score, the discriminatory power was assessed by calculating the area under the receiver-operating characteristic (ROC) curve, and calibration was evaluated by the Hosmer-Lemeshow goodness-of-fit (GOF) test. The observed mortality rate was 8.47%, and the predicted mortality rate was 6.57%. For patients aged < 18 years, the discrimination was acceptable (c-index = 0.76) and the calibration was good, with a χ² of 9.4 in the GOF test (P = 0.313). The observed mortality rate in the hemato-oncological subgroup was high (18.73%), as compared to the predicted mortality rate (7.13%), and the discrimination was unacceptable (c-index = 0.66). In conclusion, the PIM3 performed well in a Korean pediatric ICU. However, the application of the PIM3 to a hemato-oncological subgroup needs to be cautioned. Further studies on the performance of PIM3 in pediatric patients in adult ICUs and pediatric ICUs of primary and secondary hospitals are needed.

PURPOSE: The purpose of the study was to describe the experiences of do-not-resuscitate (DNR) among nurses. METHODS: Data were collected by in-depth interviews with 8 nurses in 8 different hospitals. Conventional qualitative content analysis was used to analyze the data. RESULTS: Eight major themes emerged from the analysis: DNR decision-making bypassing the patient, inefficiency in the decision-making process of DNR, negative connotation of DNR, predominance of verbal DNR over written DNR, doubts and confusion about DNR, least amount of intervention in the decision for DNR change of focus in the care of the patient after a DNR order, and care burden of patients with DNR. Decision-making of DNR occurred between physicians and family members, not the patients themselves. Often high medical expenses were involved in choosing DNR, thus if choosing DNR it was implied the family members and health professionals as well did not try their best to help the patient. Verbal DNR permission was more popular in clinical settings. Most nurses felt guilty and depressed about the dying/death of patients with DNR. CONCLUSION: Clearer guidelines on DNR, which reflect a family-oriented culture, need to be established to reduce confusion and to promote involvement in the decision-making process of DNR among nurses.

PURPOSE: The purpose of this study was to describe the essence of the experiences of patients in an ICU, and to understand them from the patients' point of view. METHODS: Participants in this study were six patients in P hospital. Data collection consisted of in-depth interviews and an observation method done from January to April in 2005. The method was analysis using the phenomenological method proposed by Colaizzi(1978). RESULTS: The themes were classified into eight theme clusters. The eight theme clusters were finally grouped into four categories, 'shock', 'pain', 'gratefulness' and 'pleasure of revival'. CONCLUSION: The ICU patients had negative experiences in physical.mental critical situations, but also positive experiences in consolation and nurses and families' encouragement. Therefore, ICU nurses must support patients and their families to minimize the negative experiences and maximize the positive experiences.
