Purpose: This study was aimed to develop the multicomponent intervention for preventing delirium among postoperative patients in a surgical intensive care unit (SICU). Methods: Using a quasi-experimental pre & post-test design with a non-equivalent control group, a total of 88 hospitalized patients in a SICU participated in this study. The 44 patients were allocated in each experimental and control group. The experimental group received the multicomponent intervention for delirium prevention including a delirium assessment and nursing intervention using a checklist, whereas the control group was provided with a standard care. The primary outcome of this study was the delirium incidence during the course of hospitalization. Results: There were no significant differences in the demographic and clinical characteristics between the two groups. The delirium occurred in 19.2% in the experimental group, whereas 38.6% in the control group ($x^2=4.526$, p<.05). Conclusion: The findings of the study demonstrated an effect of the multicomponent delirium prevention intervention in decreasing the delirium incidence rate over the standard care among the patients in SICU.

Background: The aim of this study was to investigate the effects of using a systematic approach to tracheostomy care by a clinical nurse specialist and surgical intensivists for patients with a tracheostomy who were transferred from the surgical intensive care unit (SICU) to the general ward. Methods: In this retrospective study, subjects were limited to SICU patients with a tracheostomy who were transferred to the general ward. The study period was divided into a preintervention period (January 1, 2007 to December 31, 2010) and a postintervention period (January 1, 2011 to December 31, 2014), and electronic medical records were used to analyze and compare patient characteristics, clinical outcomes, and readmission to the SICU. Results: The analysis included 44 patients in the preintervention group and 96 patients in the postintervention group. Decannulation time ($26.7{\pm}25.1$ vs. $12.1{\pm}16.0days$, P=0.003), length of stay in the general ward ($70.6{\pm}89.1$ vs. $40.5{\pm}42.2days$, P=0.008), length of total hospital stay ($107.5{\pm}95.6$ vs. $74.7{\pm}51.2days$, P=0.009), and readmission rate of SICU decreased due to T-cannula occlusion (58.8% vs. 5.9%, P=0.010). Conclusions: Using a systematic approach to tracheostomy care in the general ward led to reduction in decannulation time through professional management, which resulted in a shorter hospital stay. It also lowered SICU readmission by solving problems related to direct T-cannula.

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.

Purpose: The purpose of this study was to calculate the total daily nursing workload and the optimum number of nurses per intensive care unit (ICU) based on the nursing intensity and the direct nursing time per inpatient using the patient classification. Methods: Two ICUs at one general hospital were investigated. To calculate the nursing intensity, patient classification according to the nursing needs was conducted for 10 days in each unit during September 2018. We performed patient classifications for a total of 167 patient-days in the Medical Intensive Care Unit (MICU) and 86 patient-days in the Surgical Intensive Care Unit (SICU). The total number of person-days for nurses who responded to the Nursing Time survey was 151 for MICU and 85 for SICU. In each unit, direct and non-direct nursing hours, nursing intensity score, and direct nursing hours were analyzed using descriptive statistics such as frequency, percentage, and average calculated using Microsoft Excel. The amount of nursing workload and the optimum number of nurses were calculated according to the formula developed by the authors. Findings: For the MICU, the average direct nursing time per patient was 5.59 hours for Group 1, 6.98 hours for Group 2, and 9.28 hours for Group 3. For the SICU, the average direct nursing time per patient was 5.43 hours for Group 1, 7.21 hours for Group 2, 9.75 hours for Group 3, and 12.82 hours for Group 4. Practical Implications: This study confirmed that the appropriate number of nurses was not secured in the nursing unit of this study, and that leisure time such as meal time during nursing work hours was not properly guaranteed. The findings suggest that to create working environments where nurses can serve for extended periods of time without compromising their professional standards, hospitals should secure an appropriate number of nurses.

Purpose: Maximizing human comfort in design of medical environments depends immensely on specialized architects particularly critical care design; the study proposes Evidence-Based Design as an apparent analog to Evidence-Based Medicine. Healthcare facility designs are substantially based on the findings of study in an effort to design environments that augment care by improving patient safety and being therapeutic. On SPSS (Statistical Package for Social Science) t-test is applied to simulate two independent variables of PDR (Pre Design-Research) and POE (Post- Occupancy Evaluation). PDR is conducted on relatively new hospital Hallym University Dongtan Sacred Heart Hospital to analyse visibility from researchers' point of view, here the ICU is arranged in I-Shape. POE is applied on Dongguk University Ilsan Hospital to simulate walking on LogWare where two NS are designed based on L- Shape and Seoul St. Mary's Hospital, The Catholic University of Korea where five NS are functional for ICU Intensive Care Unit, Surgical Intensive Care Unit (SICU), Medical Intensive Care Unit (MICU), Critical Care Unit (CCU), Korean Oriental Medical Care Unit which are mostly arranged in U-Shape, and walking pattern is recognized to be in a zigzag path. Method: T-Test is applied on two dependent communication variables: walkability and visibility, with confidence interval of 95%. This study systematically analyses the Nurse Station (NS) typo-morphology, and simulates nurse horizontal circulation, by computing round route visits to patient's bed, then estimating minimum round route on LogWare stop sequence software. The visual connectivity is measured on depth map graphs. Hence the aim is to reduce staff stress and fatigue for better patients care by minimizing staff horizontal travel time and to facilitate nurse walk path and support space distribution by increasing effectiveness in delivering care. Result: Applying visibility graph and isovist field on space syntax on I- Shape, L- Shape and U- Shape ICU (SICU, MICU and CCU) configuration, I-shape facilitated 20% more patients in linear view as they stir to rise from their beds from nurse station compared to U-shape. In conclusion, it was proved that U-Shape supply minimum walking and maximum visibility; and L shape provides just visibility as the nurse is at pivot. I shape provides panoramic view from the Nurse Station but very rigorous walking.

Purpose: The purpose of the study was to evaluate the effect of the immediate postoperative nutritional status and calorie adequacy on clinical outcomes in liver transplant recipients. Methods: A total number of 99 patients who received liver transplants were recruited from a tertiary university hospital. Demography, subjective global assessment, clinical outcomes and calorie adequacy were evaluated through personal interviews, electronic medical records and dietary records. Anthropometric measures, body mass index and percent of ideal body weight were also obtained. Results: At admission to the Surgical Intensive Care Unit (SICU), the triceps skinfold thickness and mid-arm muscle circumference were significantly lower in the malnourished group than in the well-nourished group (p<.05, respectively). In the clinical outcomes, transfusion of red blood cells, mechanically ventilated hours, length of stay in the Intensive Care Unit (ICU), length of stay in the hospital, and prothrombin time were significantly higher in the malnourished group than in the well-nourished group (p<.05, respectively). The mechanically ventilated hour was significantly higher in the group with less than 50% of their required energy intake (p<.05). Conclusion: Therefore, it is important to assess the nutritional status of immediate postoperative patients. Furthermore, studies on nutritional interventions are urgently needed to provide adequate nutritional care for patients in ICUs.

Purpose: The purpose of this study was to investigate the motor subtypes of delirium in patients in a Surgical Intensive Care Unit (SICU), and identify the factors related to the characteristics of patients according to the motor subtypes of delirium. Methods: Data were collected in the SICU of a tertiary hospital in ^⁎ city from October 2018 to June 2019. Delirium was detected using the Confusion Assessment Method for the ICU (CAM-ICU) and motor subtypes of delirium were measured with the Delirium Motor Subtype Scale (DMSS)-4. Patients' characteristics were obtained by using the electronic medical records. Descriptive statistics were used to analyze the data. Results: Among 1,112 patients, 172 patients showed delirium (15.5%). After excluding dementia patients and patients refusing to participate in the study, 126 patients included in the final analysis. Delirium patients were classified as hyperactive delirium (32.5%), hypoactive delirium (42.9%), mixed delirium (11.9%), and non-motor subtype delirium (12.7%). Conclusion: The study results suggest that hypoactive delirium is the most prevalent motor subtype of delirium in SICU. More application of ventilators, more administration of sedatives, more use of catheters, and higher nursing severity were reported for hypoactive delirium cases than hyperactive ones. Therefore, it is necessary to assess early the motor subtypes of delirium using structured tools and develop appropriate nursing interventions suitable for each subtype of delirium.

연구배경: 균혈증은 중환자실에서 흔히 발생하는 문제로 일반 병실에서 보다 그 빈도가 더 높고 중환자의 사망률을 높이는 원인이 되며, 중환자실의 종류에 따라 감염의 선행요인, 원발부위, 원인 균주, 예후에 차이가 있다는 보고가 있다. 이에 저자 등은 본원의 내과계와 외과계 중환자들에서 발생한 균혈증의 임상적, 세균학적 양상과 예후 등에 있어서, 양 중환자 군 간에 차이가 있는지 알아보고자 본 연구를 시행하였다. 방법: 1990년 2월부터 1993년 12월까지 균혈증이 증명되었던 내과계 중환자 189예와 외과계 중환자 67예를 대상으로 병록을 후향적으로 검토하여 임상적, 세균학적 특징과 예후를 비교하였다. 결과: 1) 균혈증이 확인된 내과계 중환자는 전체 내과계 중환자에 비해 평균 연령이 높았으나, 외과계 중환자에서는 균혈증이 있었던 환자와 전체 외과계 중환자 간의 평균 연령의 차이는 없었다. 균혈증이 확인된 중환자는 전체 중환자에 비해 중환자실내 평균 재실 일수가 길었으며, 균혈증은 전체 평균 재실 기간을 초과한 상태에서 발생하였다. 2) 중환자의 균혈증 발생률은 내과계(7.9%)가 외과계(2.4%)보다 많았으나, 균혈증 환자의 평균 연령, 남녀비, 중환자실 재실 기간은 양 군 간에 차이가 없었다. 3) 외과계 균혈증 중환자는 내과계에 비해 균혈증 전 전신적 항생제나 부신피질 호르몬 사용, 감염과 연관된 경피적 장치, 침습적 조직이 선행되었던 경우가 많았다(전신적 항생제 사용: 내과계 45%, 외과계 63%, p<0.05; 부신피질 호르몬 사용: 내과계 14%, 외과계 36%, p<0.01; 기계장치: 내과계 19%, 외과계 39%, p<0.01; 침습적 조작: 내과계 19%, 외과계 61%, p<0.01). 4) 균혈증 획득 장소의 분포는 내과계의 경우 원외 균혈증 빈도(42%)가 외과계에 비해 상대적으로 높았고, 외과계는 중환자실내 획득 균혈증 빈도(78%)가 높았다(p<0.01). 5) 양 중환자실에서 균혈증의 원인 균주, 원발병소는 차이가 없었으며, 중환자실내 획득 균혈증의 경우 균혈증 발생 병일에도 차이가 없었다. 6) 균혈증의 원인 균주나 원발병소에 따른 예후의 차이는 없었다. 7) 균혈증 중환자의 사망률은 내과계(72.5%)가 외과(40.3%)보다 높았으며, 균혈증이 없었던 환자의 사망률에 비해 양 중환자군 모두 균혈증을 동반한 경우 사망률이 높았다(p<0.05). 결론: 균혈증을 가진 중환지는 일반 중환자에 비해 사망률이 더 높았으며, 평균 재실 기간을 초과한 상태에서 감염에 이환되고, 이는 다시 중환자실 재실 기간을 연장시키는 것으로 사료되었다. 내과 및 외과계 중환자에 따른 비교에서 내과계 균혈증 증환자는 선행 요인에 있어 간질환과 급성 호흡부전이 많았고 지역사회 획득 균혈증이 많았으며 사망율이 더 높았던 반면, 외과계 균혈증 중환자는 선행 요인으로 외상, 항생제나 면역억제제 시용 및 침습적 조작의 빈도가 많았으며 중환자질내 획득 균혈증의 빈도가 높았으나 사망률은 내과계보다 낮았다 양 균혈증군에서 균혈증의 원발 병소, 원인 균주 및 이에 따른 사망률에는 유의한 차이가 없었다.
