This study was conducted to identify factors affecting nursing performance of delirium among nursing students. A total of 252 fourth year students were recruited from nursing department in Gwangju. Structured questionnaire was self-administrated from April to September, 2017. The used statistical analysis were t-test, ANOVA, Pearson's coefficient and multiple regression analysis. Knowledge of delirium 29.0±7.24, self-confidence in the care for delirium 71.65±28.55 and nursing performance level for patients with delirium was 41.16±8.97. Nursing performance of delirium had significant positive correlations with delirium knowledge, self-confidence of delirium care. In multiple regression analysis, nursing experience for delirium patients, self-confidence of delirium care, practice experience in intensive care unit, use of nursing diagnosis related to delirium, and satisfaction of clinical practice were significant factors of nursing performance of delirium explaining 29.8% of the variables. In conclusion, to enhance nursing performance of delirium, it is necessary to develop educational program for increasing nursing experience for delirium patients during clinical practice and self-confidence of delirium care.

Purpose: The aim of this study is to examine the relationships among hospice-palliative care (HPC) nurses' knowledge of delirium, self-efficacy and nursing performance. Methods: This study was participated by 174 nurses working in the HPC unit. The nurses were asked to fill out a questionnaire that was structured to measure their knowledge of delirium, a self-efficacy in clinical performance scale (SECPS) and nursing performance. Results: The mean score for knowledge was 32.83 out of 45, with correction rate of 73%. The mean score for self-efficacy was 7.08 out of 10. The mean score of nursing performance was 2.95 out of 4. Significant correlation was observed among the variables of knowledge (r=0.28, P<0.001), self-efficacy (r=0.51, P<0.001) and nursing performance. Conclusion: Nurses with high level of knowledge of delirium showed high level of self-efficacy, and consequently better HPC nursing performance. It is necessary to develop a training program on delirium considering nurses' needs of knowledge of the condition. The effectiveness of the training program should be also examined in future.

Delirium is a common symptom in patients with terminal cancer. The prevalence increases in the dying phase. Delirium causes negative effects on quality of life for both patients and their families, and is associated with higher mortality. However, some studies reported that it tends to remain unrecognized in palliative care setting. That may be related with difficulties to distinguish the symptom from others with overlapping characteristics such as depression and dementia, and a lack of knowledge regarding assessment and diagnostic tools. We suggest that accurate recognition with validated tools and early diagnosis of the symptom should be highly prioritized in delirium management in palliative care setting. After diagnosing delirium, it is important to identify and address reversible precipitants such as medication, dehydration, and infection. Non-pharmacological interventions including comfortable environment for the patient and family education are also essential in the management strategy. If such interventions prove ineffective or insufficient to control hyperactive symptoms, pharmacologic interventions with antipsychotics and benzodiazepine can be considered. Until now, low levels of haloperidol remains the standard treatment despite a lack of evidence. Atypical antipsychotics such as olanzapine, quetiapine and risperidone reportedly have similar efficacy with a stronger sedating property and less adverse effect compared to haloperidol. Currently, delirium medications that can be used in palliative care setting require more clinical trials, and thus, clinical guidelines are not sufficiently available. We suggest that it is warranted to develop clinical guidelines based on well-designed clinical studies for palliative care patients.

Delirium is among the most common mental disorders encountered in patients with a temporary cognitive impairment such as consciousness disorder, attention disorder, and poor speech, particularly among those who are older. Delirium is distressing for patients and families, can interfere with the management of symptoms such as pain, and is associated with increased elderly mortality. The purpose of this paper is to generate useful clinical knowledge that can be used to distinguish the outcomes of patients with delirium in long-term care facilities. For this purpose, we extracted the clinical classification knowledge associated with delirium using a local covering rule acquisition approach with the rough lower approximation region. The clinical applicability of the proposed method was verified using data collected from a prospective cohort study. From the results of this study, we found six useful clinical pieces of evidence that the duration of delirium could more than 12 days. Also, we confirmed eight factors such as BMI, Charlson Comorbidity Index, hospitalization path, nutrition deficiency, infection, sleep disturbance, bed scores, and diaper use are important in distinguishing the outcomes of delirium patients. The classification performance of the proposed method was verified by comparison with three benchmarking models, ANN, SVM with RBF kernel, and Random Forest, using a statistical five-fold cross-validation method. The proposed method showed an improved average performance of 0.6% and 2.7% in both accuracy and AUC criteria when compared with the SVM model with the highest classification performance of the three models respectively.

Purpose: The purpose of this study was to develop a delirium education program for nurses and assess its effects on knowledge of delirium, the importance of nursing intervention, and nursing practice. Method: Participants comprised 60 nurses in a university hospital. The experimental group participated in a 3-hour delirium education program. Data were collected using structured questionnaires. Chi square and independent t-tests were conducted to examine similarities in demographic and dependent variables, and an independent t-test was used to test the hypothesis. Results: The experimental group obtained significantly higher scores than the control group in knowledge of delirium(t=14.52, p<.001), importance of nursing intervention(t=13.76, p<.001), and nursing practice (t=13.71, p<.001). Conclusion: Results suggest that delirium education is an effective tool to improve knowledge of delirium, importance of nursing intervention, and nursing practice. Therefore, delirium education would be beneficial for general ward and recently graduated nurses as well as ICU and experienced nurses.

Purpose : This study aimed to identify the effects of a multifaceted pediatric delirium education program for pediatric intensive care unit (PICU) nurses on their delirium knowledge, confidence in delirium nursing, and delirium evaluation accuracy. Methods : This study used a one-group pretest-posttest design. The participants were 50 nurses in two units of the PICU at S General Hospital in Seoul. All participants took a 1-hour lecture with case-based practice for the first two weeks, and received feedback as they applied the program to clinical practice over the next two weeks. Test measures were completed before and after the four week intervention period for all participants. The delirium evaluation accuracy was measured using the Korean version of the Cornell Assessment of Pediatric Delirium. Data were analyzed using the chi-square and paired t-tests. Results : After the Pediatric Delirium Education Program, nurses' delirium knowledge (x²=11.65, p =.001), confidence in delirium nursing (t=9.71, p<.001), and delirium evaluation accuracy (t=6.07, p<.001) improved significantly. Conclusions : Pediatric delirium education programs for PICU nurses were effective. For active application of the program in clinical practice in the future, various cases of childhood delirium and specific strategies for each subject must be developed. To achieve this, long-term intervention and research for multiple organizations are required.

Purpose: This study was done to identify the level of knowledge on and stress from delirium among recovery room nurses, and correlations between these factors. Methods: In this study, 125 nurses agreed to participate in the study were surveyed from October 8 to October 28, 2013. Data were analyzed using t-test, ANOVA, $Scheff{\grave{e}}$ test and Pearson correlation. Results: Average percentage of correct answers to questions about delirium was 81.9% and the mean score was 26.22 (${\pm}5.01$). The mean score for recovery room nurses' work stress from emergency delirium was 3.86 (${\pm}0.99$). Extent of knowledge on delirium significantly differed by age (F=15.017, p<.001), length of clinical experience (F=22.132, p<.001), length of recovery room experience (F=10.538, p<.001), education (F=3.312, p =.040), and marital status (t=4.107, p<.001). Stress from ED was significantly related to age (F=9.185, p<.001), clinical experience (F=7.077, p=.001), and marital status (t=-2.027, p =.045). Knowledge on delirium had a negative relationship with stress from delirium (r=-.514, p<.001). Conclusion: Results show that nurses gained knowledge of delirium from their own clinical experience indicating a need to develop educational programs to improve knowledge on delirium and plans to reduce stress from delirium for recovery room nurses.
