Purpose : This study examined the prevalence of delirium-related factors in a surgical intensive care unit (SICU). Methods : This retrospective study enrolled 73 patients who were admitted to an SICU from October 1, 2016 to March 20, 2017 and who had been hospitalized for more than 72 hours. Data was collected by reviewing electronic medical records. Results : Delirium occurred in 46 (63.0%) patients. Its related factors were age, education, mechanical ventilator, sleep, narcotics, physical restraint, and central line catheters. Conclusion : The results indicate that sleep and physical restraint are significant factors related to delirium occurrence. The results of this study can help in developing guidelines for the prevention of delirium.

Background : Intensive care units (ICUs) are generally considered epicenters of antibiotic resistance and the principal sources of multi-resistant bacteria outbreaks. The antibiotic resistance in newly opened intensive care unit that has no microbial colonization on and around the devices was investigated. Materials and Methods : The authors analyzed the antibiotic resistance patterns for common hospital acquired-pneumonia pathogens in the ICUs(Staphylococcus aureus, Pseudomonas aeruginosa, Acinetobacter spp.) at the newly opened ICU of Hanyang University Medical Center, Kuri Hospital during 6 years(1995-2000). Results : 1) Regarding Staphylococcus aureus, the resistance rate to methicillin was 15% at 1995, 21% at 1996, 20% at 1997, 23% at 1998, 22% at 1999, 55% at 2000. 2) Regarding Pseudomonas aeruginosa, the resistance rate to $3^{rd}$ cephalosporin was 50% at 1995, 50% at 1996, 78% at 1997, 40% at 1998, 77% at 1999, 39% at 2000. Imipenam was 0% at 1995, 27% at 1996, 65% at 1997, 12% at 1998, 16% at 1999, 12% at 2000. Ciprofloxacin was 0% at 1996, 56% at 1997, 36% at 1998, 57% at 1999, 58% at 2000. Tobramycin was 7% at 1995, 10% at 1996, 67% at 1997, 36% at 1998, 65% at 1999, 12% at 2000. Gentamycin was 14% at 1995, 36% at 1996, 67% at 1997, 36% at 1998, 65% at 1999, 12% at 2000. Amikacin was 14% at 1995, 30% at 1996, 61% at 1997, 16% at 1998, 39% at 1999, 18% at 2000. 3) Regarding Acinetobacter spp., the resistance rate to $3^{rd}$ cephalosporin was 92% at 1996, 89% at 1997, 88% at 1998,84% at 1999, 77% at 2000. Imipenem was 50% at 1996, 48% at 1997, 45% at 1998, 49% at 1999, 50% at 2000. Ciprofloxacin was 0% at 1996, 48% at 1997, 33% at 1998, 27% at 1999, 71% at 2000.

The purpose of this study was to identify the effects of bed baths with 2% chlorhexidine on the incidence of Methicillin-resistant Staphylococcus aureus (MRSA) and blood stream infection (BSI) and to suggest guidelines on the therapeutic bed baths using skin cleaner. This study was designed to compare the incidence of MRSA and BSI of the experimental group(n=188) who received the bed baths with 2% chlorhexidine with the incidence of MRSA and BSI of the control group(n=199) who received the existing bed baths with soap and skin cleaner. A research design used in the study was a randomized control group posttest-only design. The experimental group had 6.7% decrease in MRSA acquisition than the control group (7.4% vs 14.1%, p=.036). The experimental group was decreased in the incidence density of MRSA than the control group (9.32 cases per 1,000 patient-days at risk of experimental group vs 15.44 cases per 1,000 patient-days at risk of control group; p=.099). The experimental group had 4.5% decrease in the rate of BSI than the control group (0.5% vs 5.0%, p=.011). The experimental group was decreased in the incidence density of BSI than the control group (0.67 cases per 1,000 patient-days at risk of experimental group vs 5.52 cases per 1,000 patient-days at risk of control group; p=.052). These finding indicated that bed baths with 2% chlorhexidine is an effective nursing intervention to decrease the incidence of MRSA and BSI.

Purpose: To examine the effects of the environmental nursing intervention using eye-shields and earplugs on the incidence of delirium, environmental stress and sleep among the patients with open-heart surgery in the post-cardiac ICU(intensive care units). Method: This study was a non-equivalent control group non-synchronized design. The subjects consisted of 93 patients who received ICU care after the cardiac surgery. Among those, 32 subjects was assigned in one experimental group with eye-shields, 31 in the other experimental group with earplugs, and 30 in the control group. ICU delirium was measured by CAM-ICU, environmental stress by ICUESS, and sleep by two sleep scales developed by Oh, et al. and Kim. The data were analyzed by the SPSS 13.0 program including frequency, percentage, t-test, $x^2$ test, ANOVA and ANCOVA. Results: There are no statistically significant differences in the incidence of delirium among three groups (p=.139). The ICU environmental stress scores from the subjects of two experimental groups demonstrated lower (F=6.731, p=.002) than the control group. Also, the degrees of sleep pattern (p=.000, p=.000) and sleep satisfaction (p=.000, p=.000) were greater than those of the control group. Conclusion: Although the environmental nursing intervention using eye-shields and earplugs did not demonstrate the effects in decreasing the incidence of ICU delirium, it has affirmative effects in decreasing environmental stress and improving the quality sleep among the patients with open-heart surgery while they stay in ICU. Further nursing implications are discussed.

This research aims to provide basic materials for assisting DNR patient cares by understanding ICU nurses' awareness and ethical attitude regarding DNR. A total of 154 results were analyzed which were collected from Aug. 1st to Sep. 5th in 2014 by surveying nurses working in ICU (from 1 advanced general hospital in G metropolitan city and other general hospitals of more than 700 beds in Cheolla provinces). (1) For the decision attitudes of DNR, there were both consent and objection. Consent for the patient's opinion of rejecting further treatment and life extension despite of bad prognosis. And objection for no conducting DNR in the case of the patient's wish, treatment requested by the guardian, and CPR for the patient who has no chance. (2) Objection for artificial respirator and other treatment requested by the patient's family and the entrance of guardians into ICU. Consent for the passive use of artificial respirator by the doctor and the decrease of basic care to stabilize patients physically and mentally. No specific opinion for treatment not following aseptic techniques. Objection for frequent reports to primary care physician requested by the family. (3) Acknowledging less interest by the doctor, while supporting the health care team in the case of the guardian's complaint, objection for the DNR decision mede by the primary care physician. Objection for the DNR decision by the guideline. Objection or neutrality for straightforward explanation to the patient of bad prognosis. Objection for straightforward explanation of the patient's status (even near to death) to the patient him/herself or the guardian. In conclusion, the subject of DNR is the patient and the patient's opinion should be fully reflected. The conflict arising from the scope of medical practice and decision processes should be minimized. The standard and guideline for DNR decision is required for the ethical decision making for the patient along with agreements based on full explanations.

Traumatic cardiac injury is very rare but mortality is very high when the diagnosis and management are delayed. We reviewed our case retrospectively. Material and Method: From March 1995 to July 2003, 17 patients were diagnosed as having traumatic cardiac rupture. Five patients were stabbed, seven patients were motor vehicle accidents, four patients had fallen down, and the cause was unknown in one patient. Emergency operations were done and six patients were operated under CPB. Result: Four patients died during or after operation. The mean ICU stay period was 3.86$\pm$3.35 days and the mean hospital stay was 18.27$\pm$14.99 days. No mortality was observed in those whose vital signs were stable in the operating room. Conclusion: Preoperative vital status was very important and thoracic traumatic patient should be suspected as having cardiac injury.

This study proposes CAOPI(Computer Aided Organ Prediction Index) system based on APACHE II(Acute Physiology And Chronic Health Evaluation) for classifying disease severity and predicting the conditions of patients' major organs. The existing ICU disease severity evaluation is mostly about calculating risk scores using patients' data at certain points, which has limitations on making precise treatments. CAOPI system is designed to provide personalized treatments by classifying accurate severity degrees of emergency patients, predicting patients' mortality rate and scoring the conditions of certain organs.

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.

Purpose: Relocation stress is a common phenomenon in patients discharged from an intensive care unit(ICU) to a ward. Therefore, nurses need to be aware of the problems that can arise during the transfer process. The aim of this study was to identify nurses' experiences in transferring critically ill patients from the ICU to a ward. Method: Focus group interviews were done with 13 nurses from wards and ICU, which participated in receiving and sending of ICU patients. The debriefing notes and field notes were analyzed using the consistent comparative data analysis method. Result: Seven major categories were identified in the analysis of the data. These were 'mixed feeling about transfer', 'lack of transfer readiness', 'increase in family burden', 'uncertainty with unfamiliar environment', 'difficulty in decision making', 'difference of perception of the relationships between patients and health care providers', 'need for continuity of nursing care'. Conclusion: Transferring out of the critical care area should be presented to the patient and family as a positive step in the recovery process. However, a more universal method of passing information from nurse to nurse is needed to assist in a smooth transition.

Purpose: The purpose of this study was to identify the factors influencing nurses' caring behavior. Methods: The descriptive study included 178 intensive care unit (ICU) nurses who completed a self-report structured questionnaire. The data were analyzed using descriptive statistics, independent t-test, one-way ANOVA, and Pearson's correlation and multiple regression analysis using the IBM SPSS/WIN 23.0 program. Results: Significant correlation existed between perception of Patient- and Family-Centered Care (PFCC) and nurses' caring behaviors (r=.36, p<.001). Multiple regression analysis showed that perception of support (β=.36, p<.001), total career length (β=.33, p<.001), and familiarity with PFCC (β=.15, p=.018) affected the caring behavior of ICU nurses. These variables explained 30.0% of the variance in caring behavior. Conclusion: Effective strategies are needed to improve perceptions of support as well as to promote PFCC for increasig the frequency of caring behavior among ICU nurses.
