Purpose: This retrospective chart review study was conducted to examine the frequency of delirium and to identify the risk factors of delirium in elderly surgical patients. Methods: The subjects of this study were 394 patients aged 65 years or older who underwent surgery. The diagnosis of delirium was based on the nursing assessment records with scores from the day of surgery to the 4th day after surgery. The collected data were analyzed by binary logistic regression analysis. Results: The incidence of delirium was 4.3%, and delirium occurred most frequently on the first day of surgery and lasted for 2.16 days on average. Of delirium patients, 76.5% underwent gastrointestinal surgery, and the most common delirium pattern was disorientation. In terms of the characteristics of the subjects, the occurrence of delirium was statistically different by age (𝝌²=10.79, p=.005), systemic-specific disease (𝝌²=9.63, p=.047), use of delirium-inducing drug(benzodiazepine) before surgery (𝝌²=15.90, p<.001), walking ability before surgery (𝝌²=7.65, p=.006), history of delirium (𝝌²=35.92, p<.001), and emergency surgery (𝝌²=16.40, p<.001). As risk factors of delirium, gastrointestinal surgery was found to increase the risk of delirium by 12.57 times (95% CI=2.45~64.46, p=.002), and the use of benzodiazepines before surgery was shown to increase delirium by 10.07 times (95% CI=2.21~45.87, p=.003). Conclusion: It is necessary for nurses to actively evaluate delirium using screening tools for early detection and prevention of delirium in elderly surgical patients with delirium risk factors.

Purpose: This study estimated the incidence of delirium and associated risk factors and outcomes in ICU patients with acute poisoning. Methods: Data were collected from ICU patients over 18 years of age that were admitted via the emergency center after presenting with poisoning from 2010 to 2015. Delirium was assessed retrospectively using the Intensive Care Delirium Screening Checklist (ICDSC). Risk factors were evaluated by univariate and multivariate analysis. Results: A total of 199 patients participated in this study and 68 (34.2%) were diagnosed with delirium based on the ICDSC score. The delirium group showed a significantly higher association with prolonged length of stay in the hospital and ICU in comparison with the non-delirium group. The delirium group was associated with greater use of physical restraint. A statistically greater number of patients with pharmaceutical substance poisoning developed delirium over a short period of time than those with non-pharmaceutical substance poisoning. There was no significant difference between the two groups with respect to age, sex, past history, GCS score, vital signs, application of ventilator care and renal replacement therapy. Conclusion: The finding that the delirium group had a greater length of stay in both the hospital and the ICU is consistent with the results of previous worldwide studies of the effects of delirium on the prognosis of patients who were admitted to the ICU, suggesting the possibility for domestic application. Additionally, use of physical restraint was positively related to the incidence of delirium. Thus, interventions for minimizing the use of physical restraints and considering alternatives are needed.

Purpose: This study reviewed screening and assessment tools that are used to measure delirium in patients with cancer in hospice and palliative care settings and examined their psychometric properties. Methods: Four databases were searched for studies using related search terms (delirium, tools, palliative care, cancer, and others). The inclusion criteria were a) studies that included screening/assessment tools for measuring delirium in cancer patients receiving hospice/palliative care, and b) studies published in English or Korean. The exclusion criteria were a) studies that were conducted in an intensive care setting, and b) case studies, qualitative studies, systematic reviews, or meta-analyses. Results: Out of the 81 studies identified, only 10 examined the psychometric properties of tools for measuring delirium, and 8 tools were ultimately identified. The psychometric properties of the Memorial Delirium Assessment Scale (MDAS) were the most frequently examined (n=5), and the MDAS showed good reliability, concurrent validity, and diagnostic accuracy. The Delirium Rating Scale had good reliability and diagnostic accuracy. The Delirium Rating Scale-Revised 98 also showed good reliability and structural validity, but its diagnostic performance was not examined in hospice/palliative care settings. The Nursing Delirium Screening Scale showed relatively low diagnostic accuracy. Conclusion: The MDAS showed evidence of being a valid assessment tool for assessing delirium in patients with cancer in palliative care. Few studies examined the diagnostic performance of delirium tools. Therefore, further studies are needed to examine the diagnostic performance of screening/assessment tools for the optimal detection of delirium in patients with cancer in hospice/palliative care.

Purpose: The purpose of this study was to evaluate the incidence of postoperative delirium in elderly patients with osteoarthritis surgery and identify risk factors for its development. Methods: This study enrolled 288 patients who underwent osteoarthritis surgery in a hospital between May and November 2014. Data were collected prospectively. The Nursing Delirium Screening Scale was used to detect delirium. Multivariable logistic regression analysis was used to identify independent risk factors for postoperative delirium. Patients were also followed for outcome. Results: Postoperative delirium developed in 42 patients (14.6%). Logistic regression analysis identified old age, low physical activity, antipsychotic agents, number of catheters, and intensive care unit admission as risk factors. Worse outcomes, including increased hospital mortality, reoperation, and discharge at care facilities, occurred in subjects who developed delirium. Conclusion: Osteoarthritis surgery in elderly patients was associated with a high incidence of postoperative delirium. The results of the this study regarding patient populations vulnerable to delirium should be taken into account so that such patients could be identified preoperatively or in the immediate postoperative period.

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: The purpose of this study was to investigate the predictors of delirium in patients after orthopedic surgery. Methods: Participants were 121 orthopedic surgery patients from one university affiliated hospital located in Seoul. The instrument of Delirium Observation Screening Scale (DOS) developed by Schuurmans et al. (2003) was utilized. Data were collected from September 1st, 2010 to March 31st, 2011 and analyzed using SPSS 12.0 with descriptive statistics, t-test, chi-square test and logistic regression. Results: The delirium in patients after orthopedic surgery was occurred in 9 (7.4%) out of 121 patients. Several factors were associated with the delirium occurrence age, admission route, preadmission Activity of Daily Living (ADL), preadmission hearing aid use, preadmission walking degree, diagnosis, type of surgery, Intensive Care Unit (ICU) stay after surgery, restraint, drainage tube, time of admission to surgery, preoperative albumin and preoperative sodium. Preadmission ADL, preoperative sodium and time of admission to surgery were the significant predictors of the delirium occurrence. Conclusion: Study results may help nurses predicting and detecting delirium early and providing preventive measures to the patients with high risk of delirium after orthopedic surgery.

In Korea, elderly population aged 65 and older are about 5.0% and 10.7% in 1990 and 2009, respectively. Since elderly people may experience physiologic changes with aging and their pharmacodynamic and pharmcokinetic parameters also have been undergone changes, several adverse drug reactions can occur more frequently than young people. Especially, neuropsychiatric adverse drug reactions such as delirium and drowsiness endanger elderly patients more. The purpose of this study is to evaluate the outpatient prescriptions using drug causing delirium and drowsiness in elderly patients aged 65 and older. We retrospectively reviewed prescriptions for elderly patients collected from four community pharmacies from January 2nd to February 1st, 2010. One pharmacy was located closed to a general hospital, and others were located closed to a internal medicine or an ENT clinic. The each number of the collected prescriptions was followings; Group A (n=496) from internal medicine department of a general hospital; Group B (n=44) from ENT department of general hospital; Group C (n=144) from internal medicine clinic; Group D (n=110) from ENT clinic. In result, in Group A, the average number of prescribed drugs causing delirium or drowsiness per Rx was 2.38 In Group B, the average number of prescribed drugs causing delirium or drowsiness per Rx was 2.09 In Group C, the average number of prescribed drugs causing delirium or drowsiness per Rx was 2.51. In Group D, the average number of prescribed drugs causing delirium or drowsiness per Rx was 2.72. Especially, in Group D, the percentage of prescription that drugs causing delirium or drowsiness per Rx prescribed more than 3 is 52.73% In all the 4 groups, over the 60% of drugs causing delirium and/or drowsiness per prescription of elderly patients were prescribed. It means elderly patients take 2 drugs causing delirium and/or drowsiness among 3 drugs, which is very serious. Frequently prescribed drugs causing delirium and/or drowsiness were followings; GI agents, antitussives & expectorants, histamine H1 antagonist, analgesics, antibiotics. Among these drugs, GI agents was high raking in all the 4 groups, and pharmacists should caution elderly patients when counseling. In the internal medicine groups (Group A,C), drugs concerning chronic diseases were prescribed frequently. In conclusion, pharmacist's role is important. Pharmacists are well informed of the drugs causing delirium or drowsiness and it is important to explain about ADRs slowly and easily to the elderly patients that receive drugs causing delirium or drowsiness. And institutional device is needed. For example, when doctors prescribe drugs for the elderly patients, message is needed that supply some informations about drugs causing delirium or drowsiness.

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.

Purpose: The purpose of this study was to examine the frequency and the course of delirium, and identify risk factors for the development of delirium in surgical intensive care unit (SICU). Methods: Subjects older than 19 years admitted to the SICU were recruited. After informed written consent, enrolled subjects had baseline cognitive and functional assessments. Subjects were assessed daily for delirium using the Confusion Assessment Method-ICU (CAM-ICU). Results: During the study period, 110 patients were enrolled. The overall incidence of delirium was 20% (22/110). The average time to onset of delirium was 3.04(${\pm}1.25$) days. Several variables were associated with an increased risk of delirium including older age (p<.05), higher admission APACHE II score (p<.001), use of opioid and analgesics (p<.01), using physical restraints (p<.001), and intraoperative hypotension (p<.05). In a multivariate logistic regression model, using physical restraints (p<.001), intraoperative hypotension (p<.05), and older age (p<.05) remained significant predictors of the delirium development. Conclusion: Using physical restraints, intraoperative hypotension and older age was strongly associated with development of delirium in the SICU. Prevention measures need to focus on identifying patients at higher risk for delirium development.
